1 Foreword

Municipal solid waste (MSW) represents one of the major environmental woes all

countries are faced with and also a salient environmental concern in China. As the

economy develops, people’s wellbeing is elevated and the urbanization process accelerates,

the amount of MSW is ever-increasing and environmental pollution arising therefrom has

become ever serious. At the moment, general innocuous disposal of MSW includes

sanitary landfill, garbage power generation and comprehensive waste utilization. The

strong point of waste incineration is better decrement effect. Waste after incineration will

be 90% less in volume and 80% less in weight. In addition, the waste heat can be

effectively used to supply heat or generate power, thus, making waste new resources while

realizing MSW reduction, reutilization and reclamation. In this case, the social and

economic values are rather higher.

Pizhou City is home to one MSW yard located in the intersection of Pisui Road and

Huancheng W. Road in southwestern part of the city. The treatment process is simple

piling without the capacity of harmless disposal. The yard was completed in 1992 and

appears saturated for now. Over the years, as Pizhou realizes rapid economic and urban

development, the amount of MSW has been on the rise on a daily basis. It’s projected that

the MSW disposal capacity in Pizhou would reach 222,400t. By that time, Pizhou will be

struggled with the situation where MSW has nowhere to be absorbed. The findings of

research launched by relevant departments of Pizhou Municipal Party Committee and

Government showed that MSW of Pizhou is well-positioned to be used in power

generation and the technology has become mature. So a waste incineration power plant is

expected to be built in Pizhou.

Pizhou MSW Incineration Power Plant was invited and constructed by China

Everbright International Limited in the form of BOT. The project is located in the south of

Baiguo Road, east of Hongqi Road, west of Aishan Road in Qufang Village, Daixu Town,

Pizhou City. It is adjacent to Pingguo Road in the south and its planned area is 100 mu.



8

The expected MSW handling capacity is 600t/d with 2 mechanized grate furnaces with the

capacity of 300t/d. The installed scale is 1 straight condensing turbine of 12MW. The

equipment will be operational for 8,000hrs in a year and dispose of 220,000t/a MSW and

the annual electric energy production would be 68 MWh.

Environmental impact assessment must be carried out on the project during the

feasibility phase in accordance with the Environmental Protection Law of the People’s

Republic of China, the Environmental Impact Assessment Law of the People’s Republic

China and other laws and regulations on environmental stewardship. To this end, the

constructor entrusts Jiangsu Provincial Academy of Environmental Science to launch the

assessment, which then compiled the Environmental Impact Report on the basis of on-site

exploration, investigation, data collection and verification.

2.3 Assessment Grade and Priorities

2.3.1 Assessment grade

The environmental impact assessment grade is identified in accordance with

requirements in relevant guide rules, location, environment of the project, amount of

pollutants discharged during garbage treatment, and type of pollutants. The details are shown

in Table 2.3-1.

Table 2.3-1 Environmental Impact Assessment Rating Scale

Subjects Grade criterion Grade

identification

Ambient air

Grade distinguishment of environmental impact assessment on ambient air is

specified in Section 2.3.1.1.

Organized waste gas: the project selects NO2, SO2, PM10, HC1 and dioxins as

major pollutants to calculate the ratio of maximum ground concentration to

standard concentration Pmax ≤10％ (the maximum one is NO2, and Pmax

8.71％). The project discharges dioxins, the pollutant with serious impact on

human health or ecological environment. The assessment grade is lifted by

one grade. According to the guide rules of ambient air environmental impact

assessment (HJ/T2.2-2008), the assessment grade is Grade II.

Inorganized waste gas: specifically, as for NH3 discharged from the largest

percolate emission station, the largest Pi is 9.81%. According to the guide

rules of ambient air environmental impact assessment (HJ/T2.2-2008), the

assessment grade is Grade III.

Grade II

Surface water

Sewage water generated from the project will be discharged to

Pizhou Daixu Sewage Disposal Plant for advanced treatment and

discharge after reaching take-over standard via pretreatment in the

plant. The assessment only analyzes the feasibility of discharging to

Pizhou Daixu Sewage Disposal Plant and launches general analysis

on water environment impact.

General

impact

analysis

Noise

The acoustic functional zone of the project is Type 2 zone specified in

Acoustic Environmental Quality Standard (GB3096-2008); There are no

sensitive targets within 200m around the project upon completion (existing

sensitive targets will be removed). According to the guide rules, the

assessment type will be Type II if the acoustic functional zone of the project

is Type 1 and 2 zones specified in Acoustic Environmental Quality Standard

(GB3096), or the increase of noise level of sensitive targets within the

Grade II



24

Subjects Grade criterion Grade

identification

assessment scope before and after the construction of the project reaches 3dB

(A) to 5 dB (a) (including 5 dB (A)), or the number of population affected by

noise increases greatly”. The grade of this assessment is Grade II.

Solid waste Solid waste is only under impact analysis. /

Soil Soil is only under status quo analysis. /

Underground

water

The thickness of single layer of stratum (soil layer) of the project is ≥1.0m and the osmotic coefficient is 1.1×10

-6 to 1.26×10

-6cm/s, so the antifouling

property of theaeration zone is intermediate grade; the claypan of the

construction area is relatively thicker. The hydraulic connection among

aquifers is leak, so the aquifers are likely to be polluted; the construction site

is supply runoff area outside the water source conservation zone of drinking

water, so the level of environmental sensitivity is more sensitive; the sewage

discharge of the project is 1000m3/d, so the level of discharge is small; the

type of pollutants in sewage is = 2, the indicators of water quality calling for

predication is 6, the complexity of water quality is intermediate grade. All

in all, according to Guidelines for Environmental Impact Assessment –

Underground Water Environment (HJ610-2011), the underground water

assessment grade is Grade III.

Grade III

Environmental

risk

The environmental risk assessment type is Type II based on the type criterion,

dangerousness of materials, key hazards and identification results of

environmental sensitive areas.

Grade II

Ecology

The project site is mainly farmland, covering an area of 0.066667km2. The

ecological impact assessment is Grade III based on Guidelines for

Environmental Impact Assessment – Ecological Impact (HJ19-2011); so there

is only brief comment about ecological assessment.

Grade III

2.3.1.1 Judgment of ambient air environmental impact assessment

Criterion

The criterion for identifying ambient air environmental impact assessment is specified

in Table 2.3-2.

Table 2.3-2 The Criterion for Identifying Ambient Air Environmental Impact

Assessment

Assessment Grade Criterion

Grade I Pmax≥80% and D10%≥5km

Pmax≥80% and D10%≥5km

Grade II Others

Grade III Pmax<10% or D10%< the minimum range from pollution source to

boundary



25

Pollution source analysis

The pollution emission after the project is completed is demonstrated in Table 3.6-2,

Table 3.6-3 and Table 3.6-6 based on project analysis. The assessment selects organized and

inorganized exhaust emission sources in separate projections.

Estimation method used in result calculation

The estimation method in the recommended modes is selected according to Guidelines

for Environmental Impact Assessment – Atmospheric Environment (HJ2.2-2008); analysis

results are combined to calculate the minimum impact degree and farthest impact range of

various pollutants. The computational results are shown in Table 2.3-3, 2.3-4 and 2.3-5.

The project discharges dioxins which are pollutants with serious impact on human health or ecological

environment. The assessment grade is lifted by one grade according to the guide rules. The grade of

ambient air environmental impact assessment is finally defined as Grade II.

The Table above showed that among various pollutants discharged, the ratio of

maximum ground concentration to standard concentration Pmax of various pollutants doesn’t

surpass 10%. According to the Guidelines for Environmental Impact Assessment –

Atmospheric Environment (HJ2.2-2008), the grade of ambient air environmental impact

assessment should be Grade III. But the project discharges dioxins which is pollutant with

serious impact on human health or ecological environment. The assessment grade is lifted by

one grade to Grade II.

2.3.1.2 Grade of underground water assessment

This project is Pizhou MSW Incineration Power Plant. Sewage discharged during



30

project construction may lead to changes in underground water seepage field, water quality

and environmental issues; in the meantime, sewage will be discharged everyday. Despite of

seepage-proofing measures, there still remains danger of sewage seeping into underground

water. In this case, the planed project is Type I construction project according to Guidelines

for Environmental Impact Assessment – Underground Water Environment (HJ610-2011).

If seepage-proofing work concerning industrial waste water and domestic sewage

generated by the project is poor, it may lead to pollution to underground water quality. So

the planed project is Type I construction project. According to Guidelines for Environmental

Impact Assessment – Underground Water Environment, the assessment grade is Grade III

(Table 2.3-7) by determining the antifouling property of aeration zone, vulnerability to

pollution of aquifers of the project construction site, sewage emission intensity of the

construction project, and complexity of sewage water quality of the construction project.

(1) Antifouling property of aeration zone

The antifouling property of aeration zone is divided into three levels: strong, moderate

and weak based on the distribution of rock stratum (soil layer). The classification principle is

shown in Table 2.3-8.

Table 2.3-8 Classification of Antifouling Property of Aeration Zone

Classification Penetrating quality of rock-soil of aeration zone

Strong The thickness of single layer of rock stratum (soil layer)μ Mb≥1.0m; osmotic coefficientμ K≤10-7

cm/s; the distribution is continuous and stable

Moderate

The thickness of single layer of rock stratum (soil layer): 0.5m≤Mb<1.0m; osmotic

coefficient: K≤10-7cm/s; the distribution is continuous and stable;

The thickness of single layer of rock stratum (soil layer): Mb≥1.0m; osmotic coefficient: 10-7cm/s<K≤10-4cm/s; the distribution is continuous and stable;



31

Weak Rock stratum (soil layer) doesn’t meet the above “strong” and “moderate” conditions.

Noteμ “rock stratum (soil layer)” refers to the first rock stratum (soil layer) under the underground

foundation of the project construction site; the osmotic coefficient of rock stratum (soil layer) refers to the

vertical osmotic efficient of aeration zone in case of water saturation of rock-soil.

The burial depth of underground water level of the project is 1.1-1.2m and the elevation

of underground water level is 21.6-21.5m based on data collected and on-site exploration. So

the thickness of single layer of aeration zone is more than 1.0m. According to the rock-soil

exploration report, the second soil layer of the project area is silty clay which is featured by

continuous and stable distribution. The clay layer is relatively dense with medium

compressed earth and the thickness is 0.70-2.30m. The osmotic coefficient of the silty clay is

1.1×10-6

to 1.26×10-6

cm/s, which is smaller than 1.0×10-4

cm/s and larger than 1.0×10-7

cm/s.

According to the division principle in Guidelines for Environmental Impact Assessment –

Underground Water Environment (HJ610-2011), the antifouling property of the aeration zone

is moderate.

(2) Vulnerability to pollution of water containing stratum of the project construction

site

The feature is divided into three levels: easy, moderate and difficult. The classification

principle is shown in Table 2.3-9.

Table 2.3-9 Classification of Vulnerability to pollution of Water Containing Stratum of

the project Construction Site

Classification Location of the project site and vulnerability to pollution feature of water containing

stratum

Easy

Unconfined aquifer and area with strong permeability of lithology of aeration zone (such

as coarse sand and gravel); area with close contact between underground water and

surface water; area to the disadvantage of dilution and self-purification of pollutants in

underground water.

Moderate Area with multiple water containing stratum systems and close hydraulic connection

among different layers.

Difficult Other areas other than the above conditions

Monitoring data of underground water level demonstrated that the thickness of aeration

zone of the study area is 1.2m. As the lithology is mainly silty clay, the permeability is low.



32

This is the weak pervious bed. Experiment showed that the removal efficiency of silty clay

against pollutants (such as COD and NH3) is relatively strong. There are some rivers

surrounding the project site. At the bottom of the rivers is 20-200cm thick silt seam and we

believe it is through the seam that surface water and underground water are connected. But

the permeability is extremely low. So the connection between surface and underground water

is less closely.

Underground water in the study area mainly includes phreatic water and confined water.

Geological exploration data demonstrated that there are three layers of clay and two layers of

medium sand. The average thickness of claypan is about 5m and that of medium sand layer

is about 4m. As the permeability of claypan is small and the pollutants migrate very slowly

in the claypan, the connection among aquifers is less closely.

The above analysis showed that the aquifers of the project site are unlikely to be

polluted.

(3) Sensitivity of underground water environment

The project site isn’t a water source of centralized drinking water, but there is an

underground water well in the northwest side of the project (about 530m) (10#, refer to

Section 2.4.2 Underground Water Protection Targets), so the project site is identified as more

sensitive.

Table 2.3-10 Classification of Sensitivity of Underground Water Environment

Classification Features of sensitivity of underground water environment of the project site

Sensitive

Quasi protection area of centralized drinking water source (including active, back-up and

emergency water sources completed, active and planned water sources); other protection

areas set up by national or regional government about underground water environment

other than the concentrated drinking water source, such as special underground water

resource protection areas, including hot water, mineral water and hot spring.

More

sensitive

Supply run off area other than quasi protection area of centralized drinking water source

(including active, back-up and emergency water sources completed, active and planned

water sources); distribution area other than special underground water resource (such as

mineral water and hot spring), and scattered drinking water source, among other

environmentally sensitive area which isn’t listed into the above sensitivity classification. Insensitive Other areas other than the above areas

Noteμ 1. “environmentally sensitive area” in the Table refers to underground water related environmentally sensitive

area specified in Catalogue for Systematic Management on Environmental Impact Assessment on Construction Project. 2. If

the aquifer (water containing system) of the project construction site is located at the boundary between supply area and run

off area or between run off area and discharge area, the sensitivity class will be up by one level.



33

(4) Sewage discharge intensity of the construction project

The sewage discharge intensity of the project can be divided into three types of large,

moderate and small. The classification standard is shown in Table 2.3-11. The waste water

amount of the project is 149m3/d, which is all discharged into the municipal pipe network.

According to Table 2.3-11, the sewage disposal amount of ≤1000m3/d belongs to “small”

grade.

Table 2.3-11 Classification of Sewage Disposal

Classification Total sewage discharge (m3/d)

Large ≥10000

Moderate 1000～10000

Small ≤1000

(5) Complexity of the sewage water quality of the project

Based on the type of pollutants of waste water of the project and the number of

indicators of sewage water quality needed for projection, the sewage water quality is divided

into three types of complicated, moderate and simply. The classification principle is shown

in Table 2.3-12.

Table 2.3-12 Classification of Complexity of Sewage Water Quality

Classification Types of pollutants Indicators of sewage water

quality (number)

Complicate Number of types of

Moderate

Number of types of

pollutants ≥2

Waste waters generated from the production process of the planned project mainly

include industrial waste water containing COD, TP and ammonia nitrogen, and domestic

sewage. The types of pollutants are more than 2, the number of water quality indicators

needed for projection is less than 6. So it shall be moderate class according to Table 2.3-11.

2.3.2 Assessment priorities

Priorities of the assessment include project analysis, total quantity control, cleaner



34

production analysis, ambient air environmental impact assessment, comment on pollution

control measures and analysis of the rationality of site selection.

2.4Assessment Scope and Environmentally Sensitive Zone

2.4.1 Assessment scope

(1) Scope of ambient air assessment

According to the guide rules (HJ2.2-2008) that the diameter or length of the assessment

scope is no less than 2.5km, the assessment scope is the circle with the exhaust of incinerator

as the centre and 2.5km of radius. Please refer to Fig. 2.4-1.

(2) Scope of noise assessment

200m outside of the boundary of the construction project.

(3) Scope of underground water assessment: the assessment grade of underground water

is Grade III. The hydrogeological unit of the project location is identified based on

on-site investigation on hydrogeological conditions. According to the guide rules, the

scope of assessment is: the west side reaches Chenghe River, the east side reaches

Guanhu River, the south side reaches Beijing-Hangzhou Canal, and the north side

reaches Sanzhi Canal. It’s 6.5km long from east to west, and 7.0km long from south to

The survey showed that domestic water of Daixu Township is supplied by Wangchang

Water Plant which takes water from 10 wells in the surrounding area (7 are within the

assessment scope of the project, #4 to #10 wells) and 50m3/h is taken from every well. The

nearest #10 well is 530m from the northwest boundary of the project. It isn’t within Grade I

(30m surrounding the well) and Grade II (30-50m surrounding the well) protection range.

2.5Relevant Plans and Environment Function Zoning

2.5.1 Introduction of relevant plans

2.5.1.1 Urban Master Planning of Pizhou

Urban Master Planning of Pizhou (2011 2030) describes “urban environmental

sanitation engineering” as followsμ (1) Refuse disposal

Plan and construct Zhaodun Town Chenghe Village Refuse Disposal Plant.

Domestic wastes collected from villages and towns as well as the city proper will be

transported to Zhaodun Town Chenghe Village Refuse Disposal Plant for

comprehensive treatment.

Give priority to centralized incineration of household garbage and recycling of energy

resources; adopt new-type land-saving and sustainable waste landfill methods for residue

disposal; recycle the biogas produced by waste landfill.

(2) Refuse collection and transfer

Construct a modernized environmental health system in the city proper and put in place

a “collecting in village, transferring in town and disposing in city” garbage collection and disposal mode in villages.

Set up small-sized refuse transfer stations in villages and towns in line with local

reality. Each station has a daily disposal capacity of 100-200 tons and covers a land area

of 0.2 hectares. These stations would serve for transferring household refuse of various

villages and towns.

Establish waste collection points in villages and actively encourage rural households to

use organic refuse as organic fertilizer so as to realize reutilization of organic refuse.

We can see from the contents of the planning that the project (Domestic Waste Incineration

for Power Generation Project in Pizhou) is not included in the planning and construction

projects. But the planning mentions, “give priority to centralized incineration of domestic garbage and recycling, adopt the new-type land-saving and sustainable waste landfill method

for residue disposal, and recycle the biogas produced by waste landfill”. In addition, investigations show that the planned construction of Zhaodun Town Chenghe Village

Refuse Disposal Plant has yet to begin. According to the Introductions of the Stationing of

Domestic Garbage Incineration for Power Generation Project in Pizhou (Appendix 2)

issued by the People’s Government of Pizhou, the Pizhou MSW Incineration Power Plant will be incorporated into the revised Urban Master Planning of Pizhou (2011-2030) and the



38

project site selection conforms to the Urban Master Planning of Pizhou. Therefore, the

construction of the project does not contradict the Urban Master Planning of Pizhou

(2011-2030).

2.5.1.2 Special Plan for Environmental Health of Pizhou (2012-2030)

According to the Special Plan for Environmental Health of Pizhou (2012-2030), the

contents related to the project are as follows:

2.5.1.2.1 Planning period

The planning period is from 2012 to 2030, of which:

Short term: from 2012 to 2015;

Medium term: from 2016 to 2020;

Long term: from 2020 to 2030.

2.5.1.2.2 Planning area

The planning area is 2,085km2, covering the areas under the administrative jurisdiction

of Pizhou.

2.5.1.2.3 Plan for environmental health treatment and disposal facilities

1. Household garbage incineration plant

Accomplish the construction of the garbage incineration plant as soon as possible in an

effort to put the plant into operation by the end of 2013. The first phase of the project has a

disposal capacity of 600t/d and a reserved disposal capacity of 600t/d, of which 300t/d would

be added to the disposal capacity in the medium term and long term respectively. (That is the

project)

2. Emergency landfill site

The planning requires synchronous construction of a supporting emergency landfill.

The Phase One has a storage capacity of 300,000m3 that could meet the demand for medium

and long-term refuse disposal and reserves a storage capacity of 600,000m3 for future

expansion. The total land area will be 130,000m2. The planned emergency landfill site is

located in Lushan, Zhancheng Town.

3. Simple dump overhaul

There is a dump of domestic wastes in Pizhou at the moment. The dump covering a land

area of 59.4mu (1 mu = 0.0667 hectares) is situated in the junction of Pisui Road and



39

Huancheng West Road in the southwestern part of the city. Its treatment process is simple

dumping. This dump has now nearly one million tons garbage storage and has become

saturated. Considering effective utilization of garbage, the method of

“collection——ecological restoration” is adopted in the overhaul.

4. Fecal treatment and disposal facility

According to the plan, a fecal pretreatment plant will be constructed near the sewage

treatment plant in the northern part of the city in 2014. The plant is going to have a disposal

capacity of 100t/d and cover a land area of 4,500m2.

5. Construction of a garbage distribution site and a comprehensive treatment plant for

building wastes

According to the plan, the city would construct a building waste distribution plant in

2013 with a handling capacity of about 400t/d and covering a land area of 20mu. The site

will also be located near the Pizhou Refuse Incineration Plant. The long-term plan is to set

up a construction waste comprehensive utilization plant inside the distribution plant and

there is no plan of increasing additional land areas. The handling capacity of the plant would

be 300t/d, which will make the recycling and comprehensive utilization of building wastes of

the city a reality.

6. Kitchen waste disposal plant

A food waste disposal plant with a disposal capacity of 30t/d is planned to be

constructed in 2015. The site selected for the plant with a planned area of 15mu is located in

north of the sewage disposal plant in the northern part of the city. The project will be

expanded in the medium term. The plant’s disposal capacity is expected to be 50t/d after the

medium-term expansion and reach 80t/d after long-term expansion.

7. Water environmental health engineering facility

One water litter cleaning base is planned to be constructed in 2015. The site selected for

the base is located in the east of Beijing-Hangzhou Grand Canal and near Zhanglou. Its

planned area is 1,200m2 and its water front is no shorter than 80m.

Please see Fig. 2.5-1 for the current layout of household waste treatment facilities and

Fig. 2.5-2 for the short-term planning layout of environmental health engineering facilities.

2.5.1.3 Pollution control planning for the south-to-north water diversion project

The Pizhou Section of the Beijing-Hangzhou Grand Canal is a water sensitive area for

the East Route of the south-to-north water diversion project. Making the water delivery line

area of the East Route become a clean water way to ensure stabilization of water quality and

to meet the standard of Category is a top priority for pollution control of the Huai River

and the Hai River. For that to happen, the pollution control planning for the East Route of the

south-to-north water diversion project is to address issues related to clean water way of the

East Route and water safety in Tianjin and Jinan of the East Route. The pollution control

plan makes a clear-cut of zero pollutant draining into the water delivery line of the

south-to-north water diversion project. That means wastewater is forbidden to be drained

into the Beijing-Hangzhou Grand Canal directly.

Along the Beijing-Hangzhou Grand Canal, there are some river and canal networks and

irrigation systems that are good systems for water closure, storage, self-purification and tail

water recycling and digestion. Only a small amount of reconstruction engineering could

break up some of the current water irrigation networks and systems from the

Beijing-Hangzhou Grand Canal and other headwaters and water bodies and make them

become a relatively independent and closed system for “water closure, storage, recycling and

diversion”. The disposed tail water would be led to the system and thus can be reused in

irrigation seasons. The already existed irrigation systems could be utilized to branch and

digest tail water in motion. In the meantime, the utilization rate of tail water needs to be

increased gradually and the tail water that cannot be recycled and stored will be guided into

the Xinyi River ecological treatment system and then will be discharged to outside of the

region. The water body must be kept from major pollution incidents in the Xuzhou Section

of the East Route of the south-to-north water diversion project so as to meet the requirement

of the water quality standard of Category .

The pollutant intercepting and diversion project runs 170.28km in Xuzhou on the East

Route of the south-to-north water diversion project. This project is mainly to make use of



41

existing waterways and newly opened channels to transfer the tail water disposed by the

sewage treatment plant at the upstream to the tail water channel at the downstream and

finally discharge the tail water into deep water of the Xinyi River and then into the sea. In

this case, the tail water system on the Xuzhou Section could be separated from the delivery

line of the East Route of the south-to-north water diversion project to ensure that the water

quality of the Xuzhou Section on the East Route of the south-to-north water diversion project

meets the standard of Category . Please see Fig. 2.5-3 for the route of the Xuzhou

pollution intercepting and diversion project.

According to the Plan for Waste Treatment of South-to-North Water Diversion Project,

the Pizhou Section of the Beijing-Hangzhou Grand Canal is a water sensitive area of key

control areas. The Project makes rainwater drain into a main canal in the south of the plant.

Wastewaters are drained into Pizhou Daiwi Sewage Disposal Plant. Tail water of the plant

will not be discharged into surrounding water bodies. Rather, it will be discharged into the

sea through the diversion project.

The construction of the project meets the requirements of the Plan for Waste Treatment

of South-to-North Water Diversion Project.

2.5.1.4 Overview of Xuzhou pollution intercepting and diversion engineering in Pizhou of

the south-to-north water diversion project

The pollution intercepting and diversion engineering in Xuzhou of the south-to-north

water diversion project runs a total of 38.62 km in Pizhou, passing Suyangshan, Zhaodun,

Yunhesan Town and Zhanglou Office and running across Lijidagou, the Suzhan River, the

Shengli River, the Tantu River, the Zhong Canal and Dongfengdagou. The project is divided

into 7 tender sections, namely Zhanglou Zhong Canal Culvert Phase One, Tender 06, Tender

07, Tender 08, Tender 17, Tender 20 and Tender 25. The construction of the project with a

total investment of 180 million yuan (including relocation compensations for migrants)

started in October 2008. Please see Table 2.5-1 for specific engineering construction and

implementation and Fig. 2.5-4 for the schematic diagram of the pollution interception and

diversion engineering in Pizhou.

3.1.5 Personnel and working hours of the construction project

During peak of construction, about 131 of workers will be engaged by contractors. Most

of them are skilled 105 and unskilled 26. About 82 of workers will be contracted from



51

surrounding communities. The rest 49 will come from other areas such as Paoche town,

Guanhu town, Tiefu town and Yunhe town of Pizhou, Hongqi community, Xuzhou city and

Zibo City. Problems arising from influx of workers such as camp unauthorized camp

followers and conflict with the community is not expected. The workers accomodations are

located at Daiwei town which is approximately 5 km. from the settled communities. The

construction site is approximately 5 km. from the nearest residential house. Any adverse

impacts to the surrounding community will be mitigated through the following measures:

Control value and safety valve on the air exhaust pipelines of boiler shall be of low

noise type, air exhaust muffler shall be installed and damping treatment shall be

made for pipelines between the valve and muffler.

The fan shall be set in sound proof box and exhaust muffler shall be installed.

Vibration dampers such as rubber joint shall be installed on pumps; anti-vibration

pads shall be set on water pump and other foundations.

Building materials with good sound insulation and sound attenuation performance

shall be adopted in boiler room.

Tighten maintenance of management and mechanical equipment.

Main plant shall be arranged in a rational way to ensure concentrated distribution of

noise source; soundproof architectural structure shall be adopted in control room and

operation room.

Currently, most garbage transport vehicles of Pizhou are back loading compression

type which are airtight and prevent leakage, so the leakage of percolate along the

way can be prevented.

Upon completion, the project will employ 59 workers. These 59 new positions will be

filled up upon operations and will be open to qualified women and men.

The waste incineration and power generation process is operational 365 days every year.

It adopts the 4-team-3-shift system, with each working for 8 hours. The effective service time

of incinerators is about 8000h/y in view of equipment repair and maintenance.

3.1.6 Construction schedule

The construction schedule is 18 months.

3.1.7 Plane arrangement

The project covers an area of 66,667m2. Based on status quo and surrounding

environment of the project site, the plant is divided into four functional areas, namely major

production area (waste incineration and disposal area, power generation area), auxiliary

production area, area of transportation facilities and area of administration and living in front

of the plant. The plane arrangement is shown in Fig. 3.1-2.

Main incineration workshop is composed of waste unloading hall (warehouse, machine

maintenance room, spare parts & components room, air compression room, laboratory,

chemical water disposal room), waste warehouse, feeding area, incinerator/waste heat boiler

workshop, deslagging workshop, flue gas disposal workshop (including fly ash disposal

station and pulping workshop), turbonator workshop, deoxygenation workshop and master

control room of electrics.

Auxiliary production area includes percolate disposal workshop, circulating water pump

room, circulating water cooling tower, circulating water disposal workshop, chlorine dosing

room, industrial and fireproofing water pump workshop, industrial waste pool, fireproofing

water pool and oil tank/oil pump room. It is near the main workshop and connected by line

pipes.

The area of transportation facilities and area of administration and living in front of the

plant include plant service building, comprehensive service building (including canteen,

bathroom and living quarters for workers on work shifts), gate, entrance guard, parking lot,

accessorial building and landscape pond.

The plane arrangement is based on the principle of land conservation, compact layout

and for the benefit of construction and production management. Roads and green belts are

properly used to rationally lay out different functional zones.

3.1.8 Major public and auxiliary facilitates

(1) Water supply



53

Water sources of the project include two parts: domestic water and industrial water. The

domestic water is sourced from municipal tap water. Water used in production system,

fireproofing system, road and greenery and circulating cooling water comes from Chenghe

River (water intake permit is shown in Attachment 6 about prophase opinions). The water

delivery pipeline of the project is 3.79km long. The specific direction of water intake line and

pump station are shown in Fig. 3.1-3. The consumption of tap water is 18.2m3/d and that of

industrial water is 1,692m3/d.

Tap water

Municipal tap water is mainly used for daily lives and laboratory. Domestic water

supplies comprehensive building and water closets. The consumption is 18.2m3/d.

Industrial water

Industrial water is used for water supply of demineralized water equipment, water

supplement of circulating cooling water, flue gas cleaning and greenery. Industrial water of

the plant comes from Chenghe River. The water delivery pipes include 2 steel pressure pipes

with the pipe diameter of DN150mm. The water delivery range is about 3km. 1,692 m3/d of

water is supplied through the pipelines. There is a cleaning station in the plant and the water

treatment system is composed of coagulation, sediment and filtration system. The designed

disposal capacity is 1,700m3/d.

The project arranges chemical water preparation station to produce qualified treated

water as the make-up water for incinerator and waste heat incinerator. According to the water

load, the designed scale of the demineralized water system is 10m3/h, including two sets of

equipment, with one backup.

Based on the requirement for water quality of raw water and feed water of boiler, the

system plans to adopt reverse osmosis + EDI system to disposal of chemical water, so as to

ensure the production of stable and qualified pure water for usage.

The process for disposing of chemical water is as follows:

Raw water → raw water tank → raw water pump → multi-media filter → activated

carbon filter → heat exchanger →cartridge filter → high pressure pump → reverse osmosis



54

→ CO2 remover → intermediate water bank → intermediate water pump → EDI device →

demineralized water tank → demineralized water pump → user.

Circulating water system

Circulating water system of the plant provides cooling water for turbine condenser, air

cooler and oil cooler. Backwater for equipment cooling is returned back to reverse-flow

mechanical draft cooling tower by using overbottom pressure. The cooled water is sent to

turbine workshop for recycling via compression of circulating water pump.

The consumption of circulating water is 73, 464m3/d (3,06173464m

3/d). There are two

mechanical draft cooling towers with the type of 10NG-2000 which are arranged collectively.

The designed parameters are: temperature of inflowing water: 42℃; temperature of outlet

water: 32℃, difference in temperature: 10℃. The amount of circulating water replenished for

cooling is 1204.6m3/d.

There is one circulating water pump room installed with 3 circulating water pumps, with

2 operational and 1 backup.

Reused water system

The project uses surface water and the consumption of fresh water is lower than that of

projects of same kind; the drainage of circulating cooling water is reused to cool slag, solidify

fly ash, clean flue gas and wash garbage truck, unloading platform, ground and road; regular

drainage of boiler is used as make-up water for cooling tower. The water saving measures

help save water resources and reduce the emission of water pollutants.

(2) Drainage

Drainage of the plant area adopts the divided draindown system of industrial wastewater,

domestic sewage and rain water.

Domestic and industrial wastewater draindown system

Wastewater collection and draindown sytem of the plant includes two parts: one is low

concentration wastewater collection and draindown system which mainly collects domestic

sewage. The water quality can meet take-over requirement. This part of sewage will be

discharged to Pizhou Daixu Sewage Disposal Plant through municipal sewage pipe network



55

after being collected; the other is high concentration wastewater, mainly including waste

percolate, water used in washing ground of unloading hall. This part of wastewater will be

discharged to Pizhou Daixu Sewage Disposal Plant for retreatment after reaching take-over

standard through disposal in percolate disposal station in the plant.

Storm-water drainage system

There are rain water pipe and gutter inlet paved along two sides of roads. And the

outdoor site of buildings constitute natural slope (more than 0.3%) with roads of the plant,

that is, the outdoor site tilts naturally towards roadside and rain water will freely dredge to

gutter inlet on the road, flow into rain water well via storm sewer conduit and finally

discharge outside of the plant.

(3) Power transmission and supply

The project arranges 1 condensing steam turbine generator unit with the rated power

generation capacity of 12MW. A power generator is connected from units and boosts to 20kV

through a main transformer. 20kV bus is connected as single bus and linked to five-star

transformer substation with a 20kV circuit. The power generation is directly connected with

10kV bus which is wired by single bus section by section. The transformer used in the plant

obtains power from 10kV single bus.

(4) Automatic control

The project arranges a set of DCS and colored LCD/keyboard is used as the major

supervision and control method in the centralized control room, realizing centralized

supervision, management and decentralized control on 4 waste incinerators and supporting

waste heat boilers, flue gas cleaning system, 2 turbosets and supporting vapor water system,

and other supporting public systems.

(5) Vapor system

Every incinerator is equipped with one set of waste heat incinerator to absorb and utilize

heat generated in waste incineration and produce overheated steam necessary for turbosets.

(6) Compressed air station

It is responsible for supplying compressed air necessary for all operation points of the



56

plant, including compressed air system for plant use and compressed air system for instrument

use.

The project sets up three worm air compressors with the displacement of 24m3/min and

the pressure at expulsion is 0.75Mpa in the air compressor room with two operational and one

backup, and arranges freezing dryer and secondary filter behind the exhaust port of air

compressors to dry and filter compressed air, so as to ensure compressed air reaches the

quality for usage by various air using plots.

(7) Igniting and auxiliary fuel supply system

The system provides auxiliary fuel for incineration line and for the condition of low heat

value of waste. There is a centralized oil depot and oil pump room. 0# light diesel oil is used

as the auxiliary fuel. The annual diesel oil consumption is about 206t.

Each incinerator and boiler is equipped with 2 start-up burners and 2 additional burners.

The project arranges 1 steel oil tank above ground with the volume of 20m3, and 2 fuel

feed pumps, with one operational and one backup.

(8) Machine maintenance room

It is responsible for daily maintenance of all equipment of the plant, including repairing

components and parts, processing general non-standard components and seeking external

assistance for equipment overhaul. Frequently-used equipment is provided in the machine

maintenance room, including single girder overhead crane, engine lathe, milling machine,

planer, drilling machine, sawing machine, electric wielder and grinder.

(9) Lime slurry processor

The project directly uses lime power (CaO) as the raw materials for producing lime

slurry. Equipment of the system includes lime powder warehouse, quantified spiral conveyor

(frequency conversion control), digestion tank, slurry storage tank, lime slurry pump and

ventilation and dusty removal facility.

3.1.9 Preliminary conclusions of the Water Resources Argumentation Report

Qualified unit has been entrusted to compile the Water Resources Argumentation Report

of the project and has completed the first draft of it. The preliminary conclusions are as



57

follows:

3.1.9.1 Water taking program

The river body for the project to take water is the Cheng River. A new water pump house

will be constructed to convey water to the collecting tank inside the plant through pipelines;

domestic water is taken from city pipeline networks of tap water.

The total surface water taking volume of the project is 564,000 m3/a (70.5m

3/h) and the

maximum water draw rate is 0.02m3/s.

3.1.9.2 Water returning plan

The primary wastewater of the project includes refuse leachate, rinse wastewater and

domestic wastewater. The Project includes the construction of a leachate treatment station

with a disposal capacity of 250t/d. It is planned to adopt the “pretreatment + UASB anaerobic

reactor + MBR biological treatment system” treatment process. After being collected and

treated in the leachate treatment station, the up-to-standard garbage leachate and rinse

wastewater for taking over will be sent together with domestic sewage to Pizhou Daiwei

Sewage Treatment Plant for treatment. After the water quality meets the First Class Standard

A of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant

(GB18918-2002), the tail water will be discharged into the Xuzhou Tail Water Diversion

Engineering of the south-to-north water diversion project.

Rainwater, unpolluted waste water of circulating cooling system and desalted water

preparation system are discharged into rainwater pipe network.

The Project does not set sewage draining outlet to rivers and sewage and wastewater

enter into the emergency pool inside the plant under abnormal working conditions. The water

supply and drainage system in the plant must be constructed in strict accordance with the

“rainwater-sewage separation, clean water-sewage separation, multiple use of water” principle

to guard against mixed discharge of rainwater and sewage.

3.1.9.3 Rationality of taking and using water

The source of water of the river reach for taking water is in the Zhong Canal Xuzhou

Water Diversion Protection Zone. The water can be used for drinking, industry, agriculture



58

and shipping. Water taking of the project meets the requirements of water function zoning.

The water reuse rate and cooling water circulation rate basically meet relevant industrial

standards and the water consumption index is below the standard of Jiangsu Industrial Water

Quota (revised in 2010). The Project is rather advanced at home in water usage level and

basically rational in water taking volume. On top of that, the project is more effective in

saving water.

3.1.9.4 Reliability and feasibility of the source for taking water

(1) Reliability of water taking quantity

The total volume of surface water taken by the project is 564,000 m3 annually, relatively

less. Under the current condition of water diversion project facilities and in line with the

principle of scientific water diversion, the fact that the water administrative authority

rationally distributes water for households, shipping, electricity, industry and agriculture could

guarantee 97% of the 564,000m3 additional water supply quantity annually. After

implementing the first phase of the East Section of the South-to-North Water Diversion

Project, water taking can be more guaranteed. The Cheng River connects the Zhong Canal,

and thus the corresponding water level is at 20.64m and the watercourse depth at the intake is

2.48m when the guarantee rate is 97% based on the analysis of the average water level

between1986 and 2011. So long as the location of the water taking pump house and the floor

elevation of the water taking forebay are designed based on the water level and river bed

elevation under the guaranteed rate, then the requirement of the project for taking and using

water can be met.

(2) Reliability of the quality of water intake

According to statistics of all previous water quality analysis results in 2011, the Category

- water proportion of the source Zhong Canal was 100% throughout the year, during

flood season and non-flood season. The target rate of the water functional area is 83.3%

throughout the year, demonstrating good quality of water. The current water quality at the

water intake is Category . The content of suspended matters and the alkalinity in the water

source are greater than the requirement of circulated cooling water. The water for the project



59

needs to be treated by appropriate treatment process in the water purification station and by

the boiler make-up water treatment system and then the water quality could meet the

requirement.

With the implementation of the first phase of the East Section of the South-to-North

Water Diversion Project and the delivery of the tail water eastward diversion and recycling

project in the Xuzhou Section of the South-to-North Water Diversion Project, the water

quality in the water taking section could be further improved.

3 Feasibility of the source for taking water

The source for taking water is the Cheng River. Under the current condition of

engineering facilities of the South-to-North Water Diversion Project and in accordance with

the water supply principle of scientific diversion, 97% of the 564,000 m3 annual water

consumption volume of the project could be guaranteed. The lowest water level in the section

for taking water is lower than the daily average water level under the 97% guaranteed rate. As

long as the location of the pump house at the water intake and the floor elevation of the

forebay at the water intake are rationally designed, the requirement for taking water could be

met. The water quality could meet the requirement for production water after treatment.

In conclusion, the project’s taking water plan is feasible through optimized dispatching

of the hydraulic engineering.

3.1.9.5 Impact of taking and using water on the current status of water resource and on other

households for taking and using water

The maximum surface water draw rate of the project is 0.02m3/s. The approved annual

water taking quantity is 564,000 m3, accounting for about 0.04% of the total inflow volume in

2011 and about 0.1% of the total inflow volume under the 97% guarantee rate (2002). In this

sense, water taking of the project has little impact on the total inflow volume of the water

section for taking water.

Water taking of the project has little implication for existing water users in high flow

years and median water years and has short-term impact on agricultural water in dry season of

dry years. The Project has little influence on enterprises for taking water.



60

3.1.9.6 Water returning impact and water resource protective measures

The production and household sewage produced by the project will be discharged into

the municipal sewage pipe network after being pretreated in the leachate treatment station

inside the plant and finally into Pizhou Daiwei Sewage Treatment Plant for further treatment

to meet the First Class Standard A of the Discharge Standard of Pollutants for Municipal

Wastewater Treatment Plant (GB18918-2002). After that, they would be discharged into

Xuzhou tail water diversion engineering of the South-to-North Water Diversion Project.

Under normal discharge conditions, the tail water has little impact on water quality of the

diversion project and has no influence on water functional area and the third party nearby.

Sewage and wastewater produced under abnormal working conditions would be discharged

into the accident pool inside the plant and then into Daiwei Sewage Treatment Plant after

emergency treatment, and thus have little implications for surrounding water environment.

Clear sewage produced by the equipment circulating cooling system would be

discharged into the rainwater pipe network and the discharge volume of the entire plant is

11.0 m3/h (88,000m

3/a). The organic index content of clear sewage is low and only the

salinity is higher. The discharge of clear sewage to outside of the plant has little impact on

water environment.

The Project takes water in line with the principle of rational development, conservation

and effective protection and its water taking conforms to the plan of Jiangsu on water

resources protection and the approved plan and agreement on water distribution; supervision

and administration of water balance will be carries out, special organizations will be

established to monitor water quality, and wastewater will not be discharged to outside of the

plant; various water management systems of the plant will be set up and improved for

carrying out unified management, optimizing water allocation and ensuring the

implementation of water resources protection. After the up and running of the project, water

rates and the charge for water resources would be paid in time to guarantee normal operation

of the project.

3.2 Waste Source, Component and Heat Value Analysis

3.2.1 Amount and source of MSW

(1) Predication of MSW amount

According to the statistical data provided by Pizhou Urban Administration, the amount

of waste generated and cleaned in city area of Pizhou from 2007 to 2011 is shown in Table

3.2-1.

Table 3.2-1 Statistical Table of Waste Amount in City Area of Pizhou from 2007 to 2011

Unit: 10,000t

Year

2007 2008 2009 2010 2011

Yield 12.67 14.25 15.11 16.78 18.32

Amount of MSW cleaned in a year 8.4 8.8 9.2 9.9 10

Annual growth rate (%) — 4.8 4.5 7.6 1.0

Table 3.2-1 tells that the average annual growth rate of household refuse is around 9.7%.

Because the collection and transportation system in Pizhou is rather backward, the 5.8%

annual growth rate of waste collection and transportation capacity is still lagging behind the

growth rate of garbage output. All collection and transportation proportions keep decreasing

year-by-year. With the emphasis of the Municipal Party Committee and the Municipal

Government as well as competent departments on garbage collection and transportation

system and based on the plan on carrying out pilot programs of constructing waste centralized

collection and treatment system in Tiefu Town and Guanhu Town, the waste collection and

transportation quantity keeps rising rapidly and finally meets the requirement of Urban

Master Planning of Pizhou (2010-2030) for harmless treatment of domestic refuse.

According to Table 3.2-2, the urban per capital waste collection and transportation

quantity in Pizhou stood at 0.92 kg per person per day in 2011; the predicted per capital waste

quantity in 2010 calculated in Special Plan for Environmental Health of Pizhou is 0.81 kg per

person per day. These two data are not that much different. Based on the data of Special Plan

for Environmental Health of Pizhou, the urban per capita waste collection and transportation

quantity is 0.5 kg per person per day and the rural per capital waste collection and

transportation quantity is 0.25 kg per person per day.

According to the analysis of the waste collection and transportation quantity and growth

rate in Pizhou between 2007 and 2011 and considering the current development stage of the

city, the predicted waste growth rate in Pizhou is as follows:

The average growth rate of per capital waste collection and transportation quantity is 8%

between 2011 and 2015, 5% between 2016 and 2020, 2% between 2021 and 2030 and 1%

between 2031 and 2040.

65

We can learn from the calculated data of Table 3.2-4 that the 600t/d disposal capacity of

the first phase of the project can meet the current requirement of Pizhou for waste treatment.

However, the project needs to be expanded by constructing the third incineration line in due

time to meet the demand for waste treatment after 2016.

3.2.10 Constitutes of domestic refuse

According to the household garbage constituent report of Pizhou, the garbage in Pizhou

constitutes: 51.08% kitchen waste, 2.39% bamboo and wood waste, 8.23% fruit garbage,

8.79% paper waste, 0.45% waste metal, 12.61% waste plastic, 4.62% waste glass, 1.74%

waste fabric material, 5.62% soil sediment, 4.20% coal ash and 0.27% harmful waste. Please

see Table 3.2-5 for the numerical analysis of chemical elements of domestic wastes in Pizhou.

3.2.11 Waste heating value

According to the actual measurement result of domestic waste heating value in Pizhou in

2010, the lower heating value of household garbage in Pizhou reached 4614kJ/kg

(1104kcal/kg). After storage in garbage storehouse for 5 to 7 days and after discharging 15 to

25% leachate, the waste heating value in furnace would increase. Therefore, wastes of the

project after being stored in the storehouse for 5 to 7 days could meet the requirement that the

waste heating value should be higher than 5000kJ/kg as provided in Article 21 of Standard for

Municipal Domestic Waste Incineration Engineering Construction.

Pizhou is relatively developed in economy and has seen faster urban construction and

higher living standard. The waste heating value would rise with the economic development of

the city. Based on the common characteristics of the 1.5-2.5% annual growth rate of the

heating value of domestic waste in Chinese large and medium-sized cities, the predicted lower

heating value of waste would reach 5,127 kJ/kg by 2030.



66

With the improvement of people’s living standard and the urban waste management

standardization degree, the waste heating value would increase accordingly. Wastes would

ferment and discharge some leachate during storage, which will also result in certain increase

of the heating value. The project has identified the minimum heating value application range

of the incinerator to be 4600KJ/kg (1100kcal/kg) and the maximum heating value to

be7850kJ/kg (1875Kcal/kg).

3.4 Technological Plan to be Adopted in the project

3.4.1 Technique

(1) Process

Waste incineration method refers to the technique to dispose MSW under high

temperature in 800-1000℃ incinerator. During this process, flammable compositions of

waste undergo drastic chemical reaction with oxygen in the air, discharge heat, and turn into

high temperature combustion gas and a small amount yet stable solid residue. Combustion gas

can be recycled as heat energy while solid residue can be directly buried. This project strictly

selects process, including such systems as incinerator receiving, incineration (including

incineration and steam generation boiler, slagging and cooling, among other auxiliary

machines), flue gas cleaning, slag collection and treatment, water supply and waste heat

utilization system.

Major processes and unloading links are shown in Fig. 3.4-1.



68

Fig. 3.4-1 Process Flow Chart

(2) Process introduction

The waste will be transported to the entrance of waste receiving system by dedicated

vehicles, piled and fermented in the waste pit after weighting. In order to stabilize the

incineration process, grab bucket (crane) shall continuously spread and stir the waste to make

the waste homogenizing. After that, waste will be sent to the incinerator based on the load



69

requirement. The combustion air of the incinerator is draught from the upper part of the pit by

air blower, and be moved to the hearth as primary air. Secondary air is draught randomly from

the incinerator. When the incinerator is normally operated, waste completes the incineration

process after undergoing drying, combustion and burning up stages on the fire grate. The slag

will fall into the slag exactor and be correspondingly disposed by hydraulic device. Heat

generated in the incineration will be absorbed by the heating surface of the boiler, sent to the

power generator after generating mesothermal, medium voltage and overheating steam when

passing the superheater unit. The in-core denitrification system adopts the Selective Non

Catalytic Reduction (SNCR) method. The flue gas is purified through the flue gas cleaning

system, so that the pollutant therein is emitted into the air through the 80m high stack after the

content of pollutant in the flue gas is lower than the national limit.

3.4.2 Process design plan

(1) Selection of waste incinerator



70

At the moment, four kinds of MSW incinerators widely used at home and abroad with

mature technologies include fire grate waste incinerator, fluidized bed waste incinerator,

rotary kiln waste incinerator and waste thermal pyrolysis incinerator. Please refer to the

following table for comparison.

Compared with other furnaces, incinerator of mechanized fire grate is defined with the

following features:

Thanks to the mature technology, almost all large incineration plants use the furnace and

there are also success stories in China. It can better adapt to the features of high water content

and low heat value of wastes in China and ensure full combustion of waste. The operation is

reliable and convenient, and is highly adaptive to waste and it’s unlikely to trigger secondary

pollution. The economical efficiency is high. Waste directly enters into the furnace without

pretreatment, so the operating cost is relatively low. With long operating life, the equipment is

stable, reliable and enjoys convenient operation and maintenance. There are some supporting

technologies and equipment in China.

According to the requirement of Technical Policy for Disposal of Municipal Solid Waste

and Pollution Control issued by the Ministry of Construction, State Environmental Protection



72

Administration and the Ministry of Science and Technology, “mature technology based on fire

grate incinerator is supposed to be used in waste incineration and please remain prudent in

selecting other types of incinerators.”

Based on these reasons, incinerator of mechanized fire grate furnace is selected in the

project.

(2) Waste receiving, storage and transportation system

The system includes four parts, namely waste dump platform, waste dump gate, storage

pit, crane and grab bucket. The system is operated under enclosed condition without open-air

storage yard and manual sorting.

Waste dump platform

The platform is designed to accept various forms of trash masters so that they can

smoothly carry out waste dumping operating. The indoor platform is designed to avoid

offensive odor overflowing and rain inflow. When the trash masters will be backed off to the

positioning step at the platform which can ensure the trash masters are at proper unloading

position and prevent trash masters from falling into the trash storage pit.

Waste dump gate

Its major function is to prevent hazardous off-flavor and dust from entering into the air

from the storage pit. It separates the unloading platform from the storage and. To ensure gas

tightness and durability and rapid on-off, prevent dust and off-flavor diffusion and injurious

sects from entering into the platform, the unloading gate is an enclosed structure. It remains

closed at ordinary times and opens in case of unloading and closes upon completion. 6 waste

dump gates are arranged and adopt fluid power system which can automatically start and stop.

Waste cabin

It’s mainly designed to temporarily store wastes transported to the incineration plant. The

designed volume of the waste cabin is 10080m3

(40m long × 20m wide × 12m of average

height). According to 0.4t/m3

unit weight of waste stored in the waste pit and 600t/d of

handling capacity, it can store wastes for 7 days of disposal.

There is an exhausting inlet of primary air fan on the side near the incinerator above the



73

waste cabin which draws in off-flavor of the cabin as the combustion air, and makes the cabin

at the status of negative pressure to prevent the accumulation and overflow of off-flavor and

methane. On top of that, ventilation and deodorization system is set up on the roof of the

waste cabin so as to ensure that the off-flavor of the cabin doesn’t emit outside during the

blowing out period.

There is waste percolate collection system in the waste cabin. Percolate is discharged

from the cabin layer by layer. The side wall of the waste pool near the waste gate has been

arranged with 2 layers of grating rounds and 2 layers of rubber draining tubes, which dredge

waste percolate in the low and high places to the trench of underground vestibule and then to

the percolate collection tank. The percolate tank is near the waste cabin and seepage-proofing

measures are necessary to be taken.

Waste crane and grab bucket

The project is installed with 2 semi-automatic waste crane grabs and 3 buckets (one

backup). The volume of grab bucket is 10m3. Waste is delivered to the hearth of the feeder by

the grab bucket. There is enclosed and safeguarding observation window in the control room

of grab bucket crane which uses automatic or semi-automatic design. The crane is composed

of grab bucket, rolling up (lift-on) device, moving and sidesway device, power supply device,

operating device and feed measure device. The operation of the crane is remotely controlled

by the control room which is separated from the waste cabin and run by the operator.

(3) Waste incineration system

This system is composed of waste feeding device, incinerator body, deslagging system,

hydraulic transmission system, ignition system and combustion air system.

Process conditions of the incinerators that shall be ensured include: 850℃ or more of

flue gas temperature; no less than 2 seconds of staying time; the proportion of organics in the

slag (unburned part) shall be no more than 3%; the incinerator must be operated under

negative pressure of -50 to -30Pa.

(4) Waste incineration flue gas cooling and power generation system

A large mount of waste heat is generated in waste incineration and the temperature of

flue gas generated in the combustor of incinerator reaches 850-1,000℃. Waste incineration

system is often equipped with burning end gas cooling/waste heat recovery system with the



75

main aim of adjusting the temperature of burning end gas to fall between 200-220℃ so as to

enter into end gas cleaning system; heat energy can be used to generate power, thus reducing

the cost of incineration treatment. The project is equipped with waste heat boiler, heat

distribution pipeline and the power generator is condensing steam turbine with the power

generation capacity of 12MW.

Waste heat boiler

Every incinerator is arranged with one waste heat boiler to absorb heat generated from

waste incineration and produce overheating steam necessary for turbosets. The boiler uses

moderate temperate, pressure, single steam pocket, natural circulating boiler and the

parameters of overheating steam is 4.0MPa (G) and400℃.

The designed parameters of waste heat boiler are shown in Table 3.4-3.

(5) Flue gas cleaning system

“SNCR (in-core) + semidry method + dry method + activated carbon injection + sack”

group technology is used in flue gas cleaning.

One set of SNCR denitration device is set up which removes nitric oxide in chemical

reaction by injecting hartshorn in the first passage of the boiler, restores NOx to N2 and can

reduce the content of NOx in flue gas to somewhere below 200mg/Nm3.

Flue gas of incinerator with the temperature of 180-210℃ after heat recovery by waste

heat boiler enters into half-dry reaction tower where acid gas in flue gas undergoes neutral

reaction with Ca(OH)2 sprayed by rotary sprayer on the roof of the tower, and reduces the flue

gas temperature to somewhere between 140 and 160℃. A small amount of dust, resultant of

reaction (solid-state) and lime without full reaction gather together at the bottom of the

reaction tower while most of them enter into bag-type dust remover. Flue gas after

deacidification enters into the bag-type dust remover. The connecting tube is set with inlet for

injecting dry lime and activated carbon. And activated carbon sprayed can absorb heavy metal,

mercury vapor, dioxin and furan in the flue gas. Flue gas enters from external bag and

discharges from the roof of the separate cabin. Various particulars – dust, lime reactant and

resultant, condensed heavy metal, sprayed activated carbon – stick to the surface of the bag as

a layer of filter cake. Acid gas in flue gas reacts with excess reactant, making the removal

efficiency of acid gas higher; activated carbon further plays the absorptive role at the bag

surface. Fly ash at the external surface of the bag discharges into ash bucket of the dust

remover after back flushing of compressed air. Fly ash discharges to the embedded scraper

transporter of ash transmission system through rotary ash discharge valve. Dedusted flue gas

discharges into 80m high stack through draught fan.

(6) Lime slurry preparation system



77

It is composed of lime warehouse, slaked lime slurrying tank, dilution tank, circulating

pump and pipeline.

2 furnaces share one lime warehouse on which there is 1 bag-type dust remover which

can be automatically or manually operated when loading. Vibrator at the bottom of the

warehouse can ensure lime discharge; pneumatic turn-off valve at the discharge hole of the

storage tank is closed in case of underpart overhaul. The feeding of middle lime bucket is

controlled by starting and stopping rotation feeder and monitoring the high/low feed position.

In order to prevent the metering screw from being blocked, turn-off valve is set up at its outlet,

which ensures that the moisture of digestion tank will not penetrate when the metering screw

is brought to rest.

The lime concentration (20%) of the slurry tank is determined based on the discharge

amount of metering screw (frequency conversion control) and water added. The digested lime

flows to the dilution tank via effusion and be diluted to required concentration in the dilution

tank which is determined based on the amount of water added in the slurry tank and dilution

tank. Lime slurry circulating pump transmits the slurry to the absorption tower and the flow

speed of lime slurry in the circulating pipeline shall be calculated while taking into

consideration the efforts to prevent lime deposit and pipeline wearing. The designed flow

speed of circulating pump is much larger than the normal lime slurry use level, which

contributes to tiny change in the circuit transmission speed as a result of changes in lime

slurry consumption. In order to ensure constant pressure at the inlet of the sprayer, control

valve is used to control the pressure of the circulating pipeline. One back-up pump is arranged

which is connected to main circuit by flexible pipe.

(7) Waste water treatment system

High concentration wastewater of the project, including percolate is discharged into

municipal sewage pipe network after being disposed at percolate pretreatment station and then

reaching take-over standard. Please refer to Pollution Prevention Measures for the technique.

(8) Lime-ash disposal system

Every incinerator is arranged with 2 hydraulic slag extractors from which slag is



78

discharged and delivered to slag storage pit via vibrating conveyor, then loaded into the

carrier vehicle by the slag grab machine and shipped to resource utilization plan for

comprehensive utilization.

Fall ash collected by the ash bucket under the fire grate during the operation is delivered

to slag slot by a wet-type scraper conveyor, and discharged with slag generated by the fire

grate through hydraulic slag extractor. The wet-type scraper conveyor is set up with water

seal.

(9) Fly ash solidification system

Fly ash of the project is disposed with the technique of cement + chelant. The process is

shown in Fig. 3.4-2

Fig. 3.4-2 Fly Ash Solidification Technique

Cement is the most frequently used hazardous waste stabilizer and cement solidification

is a method of based on the cement’s function of hydration and hydraulic binding to solidify

and dispose wastes. Bulk fly ash and cement are delivered to cement solidification workshop

by dedicated carrier and stored separately. In case of cement solidification, dedicated sealed

cart is used to ship fly ash, byproducts and cement to the place near the blender. Fly ash and

cement are poured into the batch hopper according to specified proportion and certain amount

of chelant is added to increase the solidification effect. Partial ventilation is provided above

the hopper. Hoister transmits mixture to the hopper of the blender. After putting in water in

the water pool and blending for 10 minutes, solidified cement pieces will flow automatically

which will be transmitted to the storage area by the loader and maintained for days. Leaching

efficiency will be determined through sample check and qualified pieces will be transported to



79

dedicated sanitary landfill with double seepage-proofing layers.

(10) Monitoring system of the incinerator

The incinerator uses purely automatic monitoring system to supervise waste acceptance,

transportation, incineration and flue gas treatment, among various links. Online flue gas

monitoring system is set up to ensure normal operation of the incinerator and meet the

requirement for 850℃ of furnace temperature, and more than 2s of staying time of flue gas in

the hearth.

3.6 Pollutant Production, Emission and Prevention Measures

3.6.1 Major pollutant production and emission

3.6.1.1 Waste water

Wastewater of the planned project mainly includes waste percolate, domestic sewage,

wash used to clean waste unloading platform.

(1) Unpolluted waste water

Cooling system of the generator set adopts periodical feeding. In order to control the

concentration of calcium ion and magnesium in the water, some re-circulated water needs to

be discharged periodically, or condenser needs to be cleaned regularly. The cleaning waste

water stands at 343t/d, which contains a small amount of calcium ion and magnesium. Part of

the water (193m3/d) will be used for fly ash solidification, slag cooling, flue gas cleaning, and

washing ground, waste unloading platform and vehicles and the remaining part (150m3/d) will

be discharged as unpolluted waste water. Water regularly drained away from boiler is reused

for equipment cooling.

Part of reverse osmosis concentrate generated in preparing demineralized water and

drainage from water purification station will be used for greenery (36m3/d) and the remaining

part (113m3/d) will be discharged as unpolluted waste water.

(2) Amount of waste water and water quality

Waste water of waste storage system

The amount of waste percolate and composition are affected by a host of factors, and

subject to huge uncertainties. And waste percolate is one of the organic wastewaters with

more difficulty in disposal. Documentary records showed that percolate generated by

incineration plants in China accounts for 5-28% of waste disposed. Based on 600t/d of waste

disposed of the project, and 20% of percolate generated in a year, the amount of percolate is

120m3/d.

Waste perlocate is high concentration organic waste water and the concentration of major

pollution factor COD is 60,000mg/L. Waste percolate of the project is discharged to Pizhou

Daixu Sewage Disposal Plant for retreatment after reaching take-over standard through



83

disposal in percolate disposal station in the plant.

Waste water washing waste unloading platform, vehicle and waste passage.

Waste unloading area shall be cleaned to maintain a clean environment. The amount of

waste water washing waste unloading platform, waste passage and waste carrier vehicle is

about 12m3/d and the concentration of major pollution factor COD is 500mg/L. The water

will be integrated with waste percolate, discharged after reaching take-over standard through

disposal in percolate disposal station in the plant.

Domestic sewage

The discharge of domestic sewage is about 17m3/d.

The quantity and quality of waste water of various sources are shown in Table 3.6-1

according to their respective features. The water balance of the plant is specified in Fig. 3.6-1.

3.6.1.2 Waste gas

Major waste gas of the project comes from waste storage system and incineration

system. Flue gas of the incinerator merges into the flue gas cleaning system through waste

heat boiler. Flue gas of various incineration production lines adopts the combined cleaning

technique of "SNCR (in-core) + semidry method + dry method + activated carbon injection

+ bag + SCR". 2 suits of glue gas cleaning system are arranged in parallel. Standard flue

gas discharges into the air through the 80m high double-barreled cluster stack after

cleaning.

Apart from innocuous carbon dioxide and water vapor, combustion air generated from

waste incineration contains many pollutants, including dust, acid gas, heavy metal

pollutant and dioxins. The generation and emission of atmospheric pollutants are shown in

Table 3.6-2.

(1) Analysis of sources of components of glue gas is as follows:

Acid components:

HC1: MSW contains plastics and various organic chloride materials. HC1 is

generated from major chloric organics are generated after incineration and thermal

decomposition. For instance, PVC plastics, chloric waste after sterilization or whitening

generate HC1 during the waste incineration. Chlorine existing in kitchen waste in the form

of inorganic nitrogen salt (such as NaC1) doesn't generate HC1. Compared with similar

projects in Zhenjiang, Taizhou, Yangzhou and Suqian, the generation amount of HC1 of the

project is 20.01kg/h, or 160.08t/a and the emission of HC1 after flue gas cleaning

treatment is 1.00kg/h, or 8.00t/a.

HF: generates from the incineration of chlorofluorocarbons in waste, such as fluoric

plastic waste and fluoric coating. The formation mechanism is similar with HC1, but the

generation amount is relatively small.

SO2: some of SO2 comes from MSW incineration while another part comes from the

blowing out and ignition process of incinerator. Based on waste components of Pizhou and

surrounding areas, the sulfur-containing rate of waste in Pizhou is about 0.18%. If

calculated according to 80% of conversion rate of sulfur in waste is 80%, 636.6t/a of SO2

is generated during incineration. Given the sulfur-containing amount (≤0.3％) in light



88

diesel oil (annual consumption is about 60.8t/a) combusted in ignition, the total annual

amount of SO2 is 634.84t/a.

NOx: mainly comes from the thermal decomposition and oxygenated combustion of

nitrogen containing compounds, with few coming from the flame combustion of nitrogen

in the air composition (lower than 1100℃). By referring to similar projects in Zhenjiang,

Taizhou, Yangzhou and Suqian, we estimate that the generation of nitric oxide is 31.52kg/h,

or 252.16t/a. Based on similar projects, the denitrification rate of SNCR flue gas disposal

device is 40%, the emission of NOx is 151.28t/a.

CO: some comes from the thermal decomposition of carbide of waste while other

comes from incomplete combustion. The higher the waste combustion rate, the lower the

content of CO. The designed CO emission concentration of the project can be controlled at

80mg/m3, the emission of CO is 8.01kg/h, or 64.08t/a.

Smoke dust

Ash and inorganic substances of waste generate dust in combustion with some

discharged out of incinerator along flue gas flow. In addition, lime, activated carbon

powder injected during flue gas cleaning produce dust under high temperature drying of

flue gas. A larger part of ash content in waste incineration is discharged in the form of

bottom ash and smoke dust accounts for 3% to 4% of the waste. If calculated as per

incinerating 220,000t/a waste, the amount of smoke dust of the project is

7,700t/a(962.5kg/h). Large grain smoke dust can be removed through cleaning by half-dry

neutralizing tower, dry method and bag-type dust remover, discharged smoke dust is

mainly PM10.

Heavy metal

The emission identity of Hg, Cd and Pb of waste incinerator is 0.5mg/m3, 0.5mg/m

3

and 10mg/m3

respectively. The removing rate of heavy metal after flue gas cleaning

treatment can reach 90%, 90% and 99%. The generation and emission amount of heavy

waste in waste gas of the project are calculated and shown in Table 3.6-2.

Dioxin-like compound

Dioxin-like compound is the generic term of a type of compounds which can combine

with aromatic hydrocarbon receptor Ah-R and lead to a series of biochemical effects. It

app:ds:aromatic

app:ds:hydrocarbon

app:ds:receptor



89

mainly includes 75 types of polychlorinated dibenzopdioxin (PCDDs) and 135 types of

Polychlorinated Dibenzo-p-furans (PCDFs). Specifically, PCDDs and PCDFs are

collectively called dioxins. It also includes polychlorinated biphenyls (PCBs) and

Chlorinated diphenyl oxide. It's widely known that among all dioxin-like compounds, the

most toxic compounds include 7 types of PCDDs, 10 types of PCDFs and 12 types of

PCBs. And 2, 3, 7, and 8-TCDD are the most toxic. Dioxins are difficult to dissolve in

water, but easy to dissolve in fat, so they are accumulated in organism and difficult to

discharge. The biodegradability is very poor. Together with low vapour pressure, dioxins

are difficult to evaporate from the surface under normal temperature; they are thermal

arrest under 700℃ and will decompose under temperature higher than that. The three

properties determine the orientation of dioxins in the environment. They enter into

organism and accumulated via food chain, leading to transitive and accumulative

poisoning.

Dioxins have two sources: MSW includes a small amount of dioxins; Chloric

precursors generate dioxins during combustion, which include PVC, Chlorobenzene and

pentachlorophenol. Molecules of precursors generate dioxins through rearrangement,

radical condensation, dechlorination or other molecule reaction during combustion. Most

of the dioxins are decomposed under high temperature combustion. The project adopts

incinerators of mechanized fire grates and the combustion temperature in the incinerator is

maintained between 800 and 900 ℃. Flue gas can effectively decompose dioxins if

staying under 850 ℃ for more than 2 seconds.

When combustion is incomplete which generates excessive unburned matters in flue

gas, a good amount of accelerants (mainly heavy metal, especially copper) are contacted

and the temperature of environment is 300 to 500℃, decomposed dioxins under high

temperature combustion will be re-generated. So high temperature flue gas generated in

waste incineration of the project enters into flue gas cleaning system after cooling down to

200℃ in waste heat boiler, thus reducing the generation of dioxins.

Flue gas cleaning system adopts the technique of half-drying type (rotate fog)

absorbing tower + active carbon absorption + bag type dust remover. Flue gas initially



90

enters into absorbing tower and mixes fully with lime slurry of certain concentration and

reacts chemically. The acid gas in flue gas will be removed. Active carbon will be injected

between absorbing tower and bag-type dust remover so as to absorb heavy metal and

dixoins in flue gas. Flue gas reaching emission standard will be discharged into the air

through draught fan and chimney after the dust and reaction products by bag-type dust

collector the temperatures drops to 150℃.

Complicated factors are at play in generating dioxins and the concentration of dioxins

during MSW waste incineration is 5 to 10ngTEQ/Nm3. With cutting-edge technologies,

techniques and equipment, the concentration of dioxins of the project is 5ngTEQ/Nm3 and

the generation amount is about 0. 5×106ngTEQ/h.

The emission amount of dioxins of the exsting MSW incineration power generation

project of Everbright Environmental Energy (Jiangyin) Holdings Limited (handling

1,200t/d of waste) is 0.053ngTEQ/m3 (0.036～0.0996); and the figure of MSW

incineration power generation project of Everbright Environmental Energy (Changzhou)

Holdings Limited (handling 750t/d of waste) is 0.01ngTEQ/m3. The average emission

density of dioxins of Taicang Xiexin Project is 0.074ngTEQ/Nm3, that of Shanghai

Jiangqiao MSW Incineration Plant is 0.068ngTEQ/Nm3. It's projected that the dioxins

concentration of discharged flue gas can be controlled at the European and American

standard of 0.1ngTEQ/m3, and dioxins emission would be 1.0×10

4ngTEQ/h through a

series of pollution prevention measures, such as activated carbon absorption,.

(2) Waste gas of fly ash solidification workshop

Bag-type dust remover is separately set on the top of fly ash and cement cabinet,

which includes 14 filter bags and the filtration size is 24m2. Ash removal is done through

vibration. The designed wind amount is 800 to 6000Nm3/h, with 3000Nm

3/h on average.

The fly ash solidification process is all enclosed and the area is isolated from other areas.

The pollutants discharged in fly ash solidification are shown in Table 3.6-3.

(2) Odor

Project analysis showed that NH3, H2S and other odor pollutants during the project

operation mainly come from waste storage workshop, waste percolate disposal station and

ammonia water storage tank. The entire storage tank is an enclosed structure and adopts

negative pressure system, to ensure no odor outflow. Gas in the storage tank will be drawn

from the top of the waste storage pit and sent to the incinerator after preheating as primary

air for combustion supporting, so as to control the emission of foul gas. Major structures

generating foul gas during percolate disposal are sealed with cover. Foul gas is discharged

to negative pressure area of waste pit and no foul gas is discharged to the outside.

For conservative consideration, foul gases generated in waste warehouse under

abnormal conditions are estimated based on the measurement method for odor pollutants

generated in MSW landfill, mainly including NH3 and H2S. Foul gas generation

coefficients of waste warehouse are specified in Table 3.6-3.

Project expansion will add to the amount of fly ash disposal, amount of fly ash and

cement in the warehouse, and generation and emission of dust. Dust will be generated

when fly ash and cement enter the warehouse. Fly ash enters the warehouse continuously

and cement enters every 7 days for 1 hour every time. One bag-type dust remover is

separately set on the roof of fly ash storage bin and cement storage bin. Ash removal is

done through compressed-air pulse. Emission pollutants are shown in Table 3.6-6.

3.6.1.4 Solid waste

Solid wastes of the project mainly include slag, fly ash, used oil and domestic waste,

and the total amount of solid wastes is 57,685t/a.

1 Slag

Slag refers to substance left over on the hearth after combustion, including fire grate

slag and fall ash between fire grates. According to the designed data of the project, the

amount of slag of the project is 49,920t/a, accounting for 23% of the total waste. Slag of

the project will be sent to Pizhou Xutang New-type Building Materials Co., Ltd. for

comprehensive utilization to produce brick or roadbed and building materials.



95

(2) Fly ash

The project uses the technique of “SNCR (in-core) + semidry method + dry method +

activated carbon injection + bag” to dispose of flue gas generated by the incinerator.

Neutralized reactant, some under-reacted triethanolamine and waste activated carbon

collected by bag-type dust remover generate fly ash. Designed data of the project showed

that the amount of fly ash of the project is about 5520t/a (2.51% of the waste disposal

amount). The project adopts cement chelant. 7,342t/a wet ash would be generated after fly

ash stabilization. According to the National Catalogue of Hazardous Wastes, fly ash is

hazardous waste and its serial number is HW18 (802-002-18). The residue of incinerated

disposal after stabilization and solidification will be sent to Pizhou MSW Landfill upon its

completion. Please refer to Attachment 8 for the fly ash dispoal explanation produced by

Pizhou Urban Administration.

(3) Other production wastes

The project generates about 2t/a used oil.

(4) Domestic waste

It’s projected that 21t/a domestic waste could be generated, which will be incinerated

and disposed within the plant.

The amount of waste percolate and sludge of waste water is about 400t/d, which will

be incinerated and disposed with domestic waste after dehydration.

Generation and treatment of solid wastes are specified in Table 3.6-8.

3.6.2 Pollutant emission under abnormal working conditions

3.6.2.1 Fault of flue gas disposal facilities

It’s generally acknowledged that the concentration of dioxin-like matters generated

from MSW incineration is 2-10ngTEQ/Nm3. The concentration of dioxins of the project is

5ngTEQ/Nm3 while taking into full consideration technique control level of the project.

After activated carbon absorption and bag-type dust collection, the emission concentration

can be controlled below 0.1ngTEQ/Nm3.

Due to many reasons such as no injection of activated carbon or fault of draught fan,

the project needs to change spare parts or start using back-up draught fan, which lasts

about 30 minutes and will be no longer than 1 hour. This will happen 1 to 2 times every

year. Under normal conditions, bag type can be replaced in batch based on product life

cycle during blowing out overhaul. Online monitor can immediately detect bag leakage

during the operation. Bag-type dust collector of the project has several independent storage

bins which can be replaced one by one on the basis of isolated examination. In this case,

dust disposal still remains effective. This will happen no more than 2 times a year. So



97

when activated carbon and bag-type dust collection are subject to fault, disposal of dioxins

absorbed on particulates remain effective. According to research results of relevant

literatures 1

([1] Jin Yiying, Tian Honghai, Nie Yongfeng, Yin Huimin, Haiying, Chen

Zuosheng, Analysis on Dioxins in Fly Ash of 3 MSW Incinerators, Environmental Science,

V0J, 24. No. 3, 21-25), when activated carbon is added to bag-type dust collector, the

overall concentration of dioxins in fly ash rises from 254ng/g to 460ng/g. This can be

attributed to the fact that activated carbon power is collected into fly ash by bag-type dust

remover, leading to increased content of dioxins in fly ash. The above research results

showed that even without activated carbon injection, the amount of dioxin absorption in fly

ash amounts to 55% of the condition with activated carbon. The effect of dioxin disposal is

about 50-55%.

On top of that, waste incineration and disposal system of Xinmin Thermoelectricity

Co., Ltd. is half-dry method + activated carbon injection + bag dust collection and Aquatic

Dioxin Inspection Room of the Chinese Academy of Sciences detects the purified tail gas.

The test result is [2]

(Lu Gang, Technical Practice of Zero Dioxin Emission in Flue Gas of

Waste Incineration, Electric Power Environmental Protection, Vol. 21, Edition 3, 39-40):

dioxin in ash is 0.00482TEQng/m3, dioxin in gaseous phase is 0.00023TEQng/m

3. At this

rate, in case of having activated carbon injection, 95% of dioxins are absorbed in fly ash;

without activated carbon injection, some dioxins are absorbed in fly ash based on the rate

55% of absorption of with activated carbon. When activated carbon injection is subject to

fault, absorbed dioxin is 50-55% of total dioxins. The dust collection rate of bag-type dust

removal of the project would be more than 99.8%. So dioxin absorbed on fly ash can be

totally removed. Monitoring statistics showed that the highest concentration of smoke dust

would be 3 times of normal conditions, in case of leakage of bag-type dust remover. Dust

removal rate can reach 99.4% at this time; the disposal rate of dioxin can be about 50%.

This is basically consistent with the above analysis result. If the project is subject to fault

of both bag-type dust collection and activated carbon injection, it’s conservatively

estimated that more than 45% of dioxins can be disposed. The dust removal efficiency of



98

the project can reach more than 99.8%, so dioxins absorbed on fly ash can be totally

removed. According to survey and statistics, if leakage happens in bag-type dust remover,

the highest concentration of smoke dust can be 3 times of that under normal conditions. So

the dust removal efficiency at that time can still reach 99.4%, meaning that the dioxins

disposal efficiency can be about 50%, which is basically consistent with the above analysis

result. If stoppage happens to both bag-type dust remover and activated carbon injection,

it’s conservatively projected that the dioxins disposal efficiency can be more than 45%.

Under the most unfavorable conditions, that is, fault of activated carbon and bag-type

dust collection of flue gas cleaning facilities break down (lasting for about 1 hour), dioxin

emission reaches the highest amount during blowing out, if the removal rate is estimated at

45%, the emission concentration is 2.75ngTEQ/m3

and emission amount is

0.275×106ngTEQ/h.

When half-dry neutralizing reaction tower breaks down, blowing out measures would

be taken. If we consider hydrogen chloride emits abnormally which lasts for about 1 hour,

and the removal rate is 70%, then the emission of hydrogen chloride would be 6.003kg/h.

3.6.2.2 Start-stop of incinerator

When the incinerator is initiated (temperature rise), the temperature rise process of

incinerator from cold status to normal operation of flue gas disposal system lasts for 2-4

hours (temperature rise). Theoretically, a vast majority of organics can be totally burned up

in the incinerator without dioxin generation when flue gas stay 2 seconds under 850℃.

Dioxin-like matters will be generated when temperature isn’t high enough when

incinerator is initiated and closed (shut down).

Auxiliary combustion system will be started up in case of ignition (shut down), but if

measures aren’t taken properly, dioxin concentration and amount will be higher than

normal working conditions. Relevant data of Britain’s test on abnormal working conditions

when incinerator is start up of six companies showed that the concentration of dioxins at

the outlet of incinerator when incinerator is started up is 2-3 times higher than normal

standard. If no oil injection auxiliary injection measures are taken, the designer verified



99

that the dioxin concentration may reach 20ngTEQ/Nm3, most of which can be removed

through flue gas treatment and the emission intensity will not exceed 1.0ngTEQ/Nm3.

Under the most unfavorable conditions when two incinerators need to shut down

simultaneously, the waste gas amount is lower than normal conditions at about 70,000m3/h.

Dioxins emission is 70,000ngTEQ/h, which will last for no more than 1 hour.

3.6.2.3 Foul odor emission under abnormal working conditions, such as incinerator

overhaul

There are three reasons, making foul odor pollution prevention measures unusable and

invalid: when incinerator is shut down, primary air fan stops drawing gas from the waste

tank, air curtain device is subject to fault and stops operating, waste tank is damaged in a

large scale and isn’t enclosed any more. The first one exerts the largest impact, happening

one or two times at most every year and lasting 2-4 days.

When one of the two incinerators is overhauled, foul odor of waste pit will be drawn

by fair fan to another incinerator and burned by it. But in unexpected cases, 2 incinerators

are shut down, major foul odor comes from waste pit which couldn’t be burned by the

incinerators. The project plans to set up activated carbon deodorization device on the

platform of the side wall of waste pit. Foul odor of the waste pit will be drawn by the

draught fan to the device, deodorized by the device and discharged from 80m exhaust

funnel (main stack).

When the incinerator is overhauled, the project plans to use activated carbon

deodorization device. Activated carbon’s deodorization rate can be more than 80%, and its

foul odor absorption and cleaning effect is much higher than other methods and can purify

several types of smelly substances. It’s suitable for continuous use for short term. The foul

odor pollutant emission of the project is shown in Table 3.6-9 which shows that NH3 and

H2S can meet the requirement of Odor Pollutants Emission Standard (GB14554-93).

4 Survey and Report on Environmental Status Quo

4.1 Profile of Natural Environment

4.1.1 Geographical location

Pizhou City is located in the north of Jiangsu Province, just between Xuzhou and

Lianyungang. On the east of Pizhou is Xinyi City, the west is Tongshan County and

Jiawang District of Xuzhou City, with Suining County and Suyu County of Suqian in

the south, and bordering Shandong Province to the north. Pizhou City’s east longitude is

117°35 50 118°10 40 , and north latitude is 34°07 -34°40 48 . The City is 52

kilometers long from east to west, and 61 kilometers from south to north.

The planned site of the project is to the north of Qufang Village of Daiwei County,

Pizhou City, the south of Baiguo West Road, east of Hongqi Road, West of Taishan

Road, with Pingguo Road to its south. The site is about 4500m south to the border of

Pizhou urban area, 4000m southwest to the Middle Canal, 3500m west to the Chenghe

River, 2500m east to the Guanhu River, and 9500m north to the Aishan 220kV

transformer substation of Chengxi Village, Picheng County.

Please refer to Fig 4.1-1 for the geographical location of the project.

4.1.2 Topography and landform

4.1.2.1 Topography and landform

Xuzhou is part of the large-scale descending areas of Northern Jiangsu Plain.The

terrain there is low and flat, with deep sendiments inside the graben basin (hundreds to

thousands of meters), featuring co-shaking characteristics.

Pizhou City, in which the project is located, situated at the edge of alluvial fan plain

in front of the Yimeng mountain area, to the north of Xubang uplifted zone.The entire

area tilts from northwest to southeast, the higheast being 20 – 33m.The northwestern

and southwestern parts are limestone denuded hills, which is mountainous, with other

mountains scattered in the south, middle and north.In Pizhou City, plain lowlands are

the main terrain, about 51.7% of the total area, plain slops being 27.1%, mountain area



103

being 4.9%,and water areas being 16.3% of the total area.

The site where the project locates is of flat terrain, with average elevation of 19 to

30m (Fig. 4.1-2). There are water source supply wells, the rate of flow of each can be 50

m3/h.

Fig. 4.1-2 Figure of the topography and landform of the research area

4.1.2.2 Regional stratum

The main exposed stratums within the area: Neoproterozoic Qingbaikouan system,

simian system, Cambrian system of Paleozoic Eratherm, middle and lower parts of

Ordovician system,carboniferous system,Permian system,and the fourth system of

Cenozoic Erathem.The unconsolidated sediments of the fourth system are mainly

diluvial mild clay, sandy loam, and silt, with the depth of 0 to 30m typically,where

Liuxin and Jiahe areas to the west are deeper, of about 60m, while in Pantang area in the

southeast,it is about 40m deep; the bedrocks in the area are mainly carbonate rocks of

Cambrian system and Ordovician system.

The stratum of Pizhou City is incomplete, with the Tumen group of Neoproterozoic

Qingbaikouan system and the Simian system being the oldest stratum,Cambrian system

the only one of Paleozoic Erathem,and cretaceous system being the only one of



104

Mesozoic Era. The Cenozoic Erathem is well developed.

4.1.2.3 Regional Tectonics

The main fault in this region is the ancient Yellow River fault zone, composed of

four 28 km long, 800 to 1000m wide paralleled faults, which are mainly tensional and

tension-shear faults.The breaking of rocks and development of fracture and karst in the

fault zone make it a serious fracture karst development zone. The fold in this region is

mainly anticlinorium in Xuzhou, the axial trend of which starts from 50°-60°, to

20°gradually north to south, and protrudes to the northwest, forming an arch shape. The

core part of the zone is Tumen group stratum of Qingbaikouan System, stratums of

Ordovician system and cambrian system on both wings; the karst water system in the

entire region is divided by the water blocking structure of the core part of Xuzhou

anticlinorium, into two subsystems to the east and west, which are connected by the

ancient Yellow River fault zone.

The main tectonic types in Pizhou are north-east direction tectonics, east-west

direction tectonics and north-west direction tectonics.

1 North-east direction tectonics:

Aishan Mountain compound anticline: the core runs along Yashang Mountain

to Aishan Mountain, which is Tumen group and Chenshan formation; both wings are

Zhaowu and Zhangqu formation.

Zhaodun - Guomanshan Mountain compound syncline: Spread along

Guomanshan Mountain, the core is Jingdingshan formation, and both wings are Niyuan

formation.

Zhancheng - Zhanglou anticlinorium: core is Chengshan formation, and both

wings are Zhaowu formation, Niyuan formation and Jiudingshan formation.

Picheng fault zone: spread from north to south along Picheng to Xulou, its

section is tilting from south to east, the angle of inclination is 70° There is breccia

development in the fault zone, with the feature of multi-phase activity.

Bayiji depressions: along Bayiji to Xuliu area, extending outside of the region



105

to the southwest. It is about 22km long and 2 - 5km wide within the region. Inside of the

depression zone is Wangshi formation from Cretaceous Period, and both wings are

Sinian system.

Gangshang fault depression trough: Baibu - Gangshang area, 24km long and

10km wide, lying below the upper cenozoic group. Sediments inside are Beishan

formation.

(2) East-west direction tectonics

The tectonic feature of east-west tectonics is Sihu depression, spreading along

Xingloubei - Sihu- Zouzhuang, with the upper being covered by the quaternary system,

and the lower being composed of the paleogene system.

(3) North-west direction tectonics

The north-west tectonics are mainly faulting tectonics, and the main tectonic

feature is Tushan fault, which spreads along Tushan - Balu, with both ends extending

outside of this region. The fault zone within the region is about 33km long, its section is

tilting from south to east, the angle of inclination is 45 - 48°, cutting through all

north-east tectonics, and is of the feature of multi-phase activities.

4.1.3 Weather

Pizhou belongs to the typical northern temperate zone, with four distinguished

seasons. The prevailing wind directions every year is northeaster and east wind, with the

maximum wind speed of 27.2 m/s. The yearly average temperature is 14.2℃, and the

highest is 39.8℃, and the lowest is 17℃ below zero. The average annual rainfall is

867.8mm, the highest being 1365.8mm

4.1.4 Surface Water Resource

The rivers in this region belongs to the Yishusi water system of Huaihe River Basin.

Yishusi water system originates from Yimeng mountain area of Shandong Province,

mainly composed of Yihe River, Shuhe River, Sihe River. Yihe River flows through

Linyi all the way south into Jiangsu Province, to the Luoma Lake; one stream of Shuhe

River flows all the way south into the new Yihe river, and the other flows east through



106

Shuhe River into the Yellow Sea; Sihe is also called Nansihu water system, which is the

general name of four interconnnected lakes — Nanyang Lake, Dushan Lake, Shaoyang

Lake and Weishan Lake. A secondary dam project was built at the narrow point of the

middle of the lakes in 1960, dividing the lakes into upper lake (Shaoyang Lake)and

lower lake (Weishan Lake). There are two outlets for the flood of Nansihu river

system— Hanzhuang and Jiaba. The flood flows through Middle Canal, Yijia River and

Grand Canal (Bulao River section) into Middle Canal. Through the storage of Luoma

Lake, most of the flood flows into the sea through New Yihe River, and a small part of

the flood flows south along Middle Canal and into the sea through ancient Yellow River.

Normally, the rivers flow from west to east, and from north to south, and will be

adjusted to be from east to west and from south to north during South-to North water

diversion period. The Grand Canal, Bulao River and Middle Canal are the rinsing

channel for South-to-North water diversion.

At the project location, Guanhu River and Xuma River are for irrigation and water

draining. The ancient canal is only for sightseeing. The ancient canal and Xuma River

flow into Guanhu River. There are control sluices where Guanhu River enters Middle

Canal, which will only be open for drainage. The industrial water of the project is taken

from Guanhu River, and the water drained from the project will be reused after being

treated in the sewage treatment plant. Only rainwater will be discharged into nearby

channels, with no influence on the South-to-North water diversion project.

The distribution of water systems in the region where the project is located is

specified in Fig. 4.1-3.

4.1.5 Underground Water Resource

The types of underground water in Pizhou area are pore water hosted in the

unconsolidated formation of upper Cenozoic Group, fracture karst water hosted in

the carbonate stratum, and fracture water hosted in the magmatic rock.Based on the

lithological association characteristics of the aquifers and the burial conditions,

pore water can be divided into upper holocene series - middle pleistocene series



107

shallow pore phreatic water - weak confined water, and lower pleistocene -

Neogene system deep confined water. Since the fracture karst water and fracture

water are not really important to water supply, thus we will only discuss the

relevant hydrogeologic conditions for pore water.

(1)Upper holocene series - middle pleistocene series shallow pore phreatic

water - weak confined water: distribute in all area except bedrock hilly regions. Its

aquifer is 10 - 65m deep, and is mainly sand,conglomeratic sand, sand loam and

silty clay with calcium-iron-module.The aquifer is rich in groundwater, the water

inflow per well in the regions to the west of Chefu Mountain - Suyang Mountain -

Bayiji - Tushan Mountain, is 100 - 1000m3/d and 1000 - 3000m

3/d in regions to the

east the line. The main recharge sources are the infiltrat ion of atmospheric

precipitation and irrigation water. Evaporation, artificial pumping and leakage

recharge to lower aquifer are the main way of water draining. The main form of

underground water movement is vertical water exchange, and horizontal runoff i s

rather slow. The burial depth of the underground is typically 2 to 5 meters.The

groundwater dynamic belongs to the type of infiltration-evaporation, is mainly

controlled by the meteorological condition, and only fluctuates with the change of

meteorological cycle, with no tendency to rise or fall. Except 16 counties,

including Tushan, Pizcheng, Sihu, Chahe, Daizhuang, Yunhe, Yitang, Suyangshan,

Paoche, Nianzhuang, Guanhu, Daiwu, Zhancheng, Bayiji, Chenlou, Tiefu, the

water is mainly 2-A and 4-A water, with degree of mineralization less than 1g/L,

the total hardness around 300mg/L, and F- less than 1mg/L, generally meets the

water quality requirements of domestic water and industrial and agricultural water

supply.

(2) Lower pleistocene - Neogene system deep confined water: distribute

mainly in the regions to the east of Zouzhuang - Chahe - Lianfang - Baibu - Hongqi

- Bayiji - Zhaodun - Xutang - Xinhe.The burial depth of the top layer of the aquifer

is 50 - 70m deep, and the burial depth of the lower layer is less than 100m, 10 -



108

60m thick, mainly silty clay, mixed with silt and sand layer. The aquifer is low in

water richness.The water inflow per well at the east of Gangshang, Paoche and

Xinhe is relatively higher, over about 1000m3/d, and around 1000m

3/d in other

areas. The burial depth of waterhead is usually less than 5m. The main recharge

sources are the leakage recharge from aquifers above it and the lateral runoff from

the direction of Shandong in the north.The underground water runs from north and

northwest to south and southeast. Artificial pumping and external flow to the

outside of the region are the main way of water draining. The water level is smooth,

with no tendency of rise or fall.The water is mainly 4-A and 1-A water, with degree

of mineralization less than 1g/L, the total hardness around 100mg/L, and F- less

than 1mg/L, suitable for drinking.

4.1.6 Soil Resources

The total area of Pizhou City is 2088 square kilometers (3,127,700mu), where

arable area takes up 54.07% (1,691,300 mu), forest and garden fields takes up 11.19%

(350,000 mu), with arable land per capita about 1.34 mu.

4.1.7 Biological Resources

The main vegetation species in this region are mainly wheat, rape, corn, bean,

cotton and other commercial crops; but types of animals are few. The biodiversity of

this region is not high.

Note: not detected is expressed as “detection limit L”.

We can conclude from Table 4.3-4 that hourly and daily average concentration of

normal factors SO2, NO2 and PM10 reaches the Grade 2 standard requirement in The

Ambient Air Quality Standard (GB3095-1996); special factors HCl and Hg are not

detected. H2S , HCl, Cd, NH3, and Pb all meet the maximum acceptable concentration

requirement for harmful substances in the air of residential community specified in

Hygienic standards for the Design of Industrial Enterprises (TJ36-79).

4.3.1.2 Status review (based on The Ambient Air Quality Standard (GB3095-1996))

Status review on atmospheric environmental quality is carried out by the simple

factor appraisal method and the computational formula is as follows:

i

i

iS

CP

Where,

Pi – evaluation number of certain pollution factor i

Ci – concentration value of certain pollution factor i, mg/m3

Si – standard value of atmospheric environmental quality of certain pollution factor

i, mg/m3

The calculation result of the ratio of maximum ground concentration is shown in

Table 4.3-4.

The calculation results show that the ratio of maximum ground concentration of

PM10, SO2, NO2, HCl, NH3, H2S, Hg, Pb and Cd of various monitoring sites is less than

1. Major indicators of atmospheric environmental quality is better than Grade 2 standard



116

requirement in The Ambient Air Quality Standard (GB3095-1996) and the requirement

in Hygienic standards for the Design of Industrial Enterprises (TJ36-79), which means

that the environmental quality remains sound in the evaluation region.

4.3.1.3 Status review (based on The Ambient Air Quality Standard (GB3095-2012))

Compared with The Ambient Air Quality Standard (GB3095-1996), The Ambient

Air Quality Standard (GB3095-2012) is only different in the standard value of NO2

when it comes to status quo monitoring factors. So only NO2 is evaluated according to

the new standard.

(1) Evaluation standard

The standard value of monitoring factor NO2 (GB3095-20112) is specified in

Table 4.3-5. And the evaluation conclusion of other monitoring factors, including SO2,

PM10, HCl, NH3, H2S, Hg, Pb and Cd is similar with that in Section 4.3.1.2.

(3) Evaluation conclusion

Table 4.3-6 showed that the ratio of maximum ground concentration of NO2 of all



117

monitoring sites is less than 1, meeting the Grade 2 standard requirement in The

Ambient Air Quality Standard (GB3095-2012).

(2) Evaluation result

Table 4.3-10 shows that, monitoring factors of Chenghe River meet type III standard

requirement specified in Surface Water Environmental Quality Standard (GB3838-2002),

except ammonia nitrogen, total phosphorus and BOD5. Monitoring factors of Guanhu River

meet type III standard requirement specified in Surface Water Environmental Quality

Standard (GB3838-2002), except total phosphorus, ammonia nitrogen, potassium

permanganate index and BOD5.

Reasons for exceeding the standard:

With the development of middle and small-sized corporations and private

enterprises in the water basin, the environmental protection facilities can not meet the water

treatment requirements, and the environmental management is ineffective either.

With the rapid growth of population, sanitary sewage cannot be treated totally, thus

affecting the water body.

Polluted by the objects dropped during the port handling process, waste from inland

water transportation and the use of chemical fertilizer in the farmlands on both sides.

For the purpose of improving the water quality of Grand Canal, besides the tail water

diversion projects, the government of Pizhou City has also developed comprehensive water

environment regulation scheme, mainly:

Perpare to construct Daiwu Sewage Treatment Plant, to treat the industrial sewage from

coking and chemical plants in the economic development area of Pizhou, and the treated tail

water will flow into the Tail Water Diversion Project of Xuzhou.

Strengthen the environmental management of the Grand Canal transportation, build

ship garbage collection point and access facilities in Pizhou port, to collect domestic garbage

on ships into the port. Oily sewage and sanitary sewage will be pumped ashore through tubes

into the sewage pipe network of the City. No sewage from the ships shall be discharged into

the Canal.

Strength the control over the disposal of solid waste on the bottomland and



126

agricultural nonpoint source pollution of both sides. Adopt regional nutrient management

and precise fertilizing technology. Displace certain chemical fertilizer with organic fertilizer,

to reduce the application rate of chemical fertilizer; displace chemical pesticide with

biopesticide, to reduce regional agricultural nonpoint source pollutant emissions.

Through the above measures, the water environment of Grand Canal Pizhou section will

be improved significantly. Comprehensive water environment regulation scheme is specified

in the Attachment.

Compared with Table 2.2-10 Underground Water Quality Standard (GB/T14848-93),

we can find that underground water quality of five monitoring sites meets Type III water

quality requirement in Underground Water Quality Standard (GB/T14848-1993).

Underground water environment remains sound.

4.3.6 Status quo monitoring and review on dioxin

According to the requirement of Document No. H. F. [2008] 82, before the trial run of

any waste incineration power plant, monitoring sites shall be arranged at the nearest sensitive

spot in downwind area to the yearly prevailing wind direction of the plant site, and at the

spot with the highest pollutant ground level concentration, to monitor the dioxin in the

air(According to Chapter 2.3.1.1 Determination of Level of Assessment of Atmospheric

Environment Influence, the highest ground level concentration of pollutants from incinerator

off-gas emission shall not be higher than 850m); one monitoring site shall be arranged at the

upwind and downwind area of the prevailing wind direction of the plant site respectively, to

monitor the dioxin in the soil. For the downwind area, planting soils near the spot with the

highest pollutant ground level concentration are recommended. Status quo monitoring and

review on dioxin shall be carried out according to the above arrangement.

The constructor entrusted Taizhou Environmental Monitoring Center to launch status

According to the survey, the completed enterprises around the project are Jiangsu

Yizhou Coking Co., Ltd, three wood processing plants to the south(Xufu, Jinxin and Jialin),

and Li Hua Livestock & Poultry Co., Ltd.; the project in process is National Bio Energy

Group Pizhou Biomass Power Generation Project. Refer to Fig. 4.4-1 for detailed

information. Due to their characteristics and small size, the sewage water from the three

wood processing plants (Xufu, Jinxin, Jialin) and Li Hua Livestock & Poultry Co., Ltd.

(which is a trading enterprise, and doesn't carry out producing activities, including

livestock breeding) is mainly sanitary sewage, which can be discharged into the

surrounding river after simple treatment; National Bio Energy Group Pizhou Biomass

Power Generation Project is still in progress, and according to the official reply to the

environment assessment, the sewage water from it shall be pre-treated to meet the

take-over standard and then be treated in the Cheng Bei Sewage Treatment Plant before



137

being discharged. Jiangsu Yizhou Coking Co., Ltd. has already been put into service, but

has not gone through the acceptance inspection. According to the official reply to the

environment assessment, he sewage water from it shall be pre-treated to meet the take-over

standard and then be treated in the Cheng Bei Sewage Treatment Plant before being

discharged. However, due to the long distance between the Jiangsu Yizhou Coking Co., Ltd.

and Cheng Bei Sewage Treatment Plant, and because the pipe network has not been

connected yet, certain amount of the sewage water is treated and reused within the

company, and the rest which cannot be reused is entrusted to be transported and treated by

qualified organization.

With Daiwu Sewage Treatment Plant be completed and put into service, the sewage

water from the above enterprises will be treated and discharged after being pre-treated

within the company respectively.

The emissions from various sewage pollution sources within the evaluated area are

5 Environmental Impact Prediction and Assessment

5.1 Analysis on Environmental Impact during the Construction Period

The construction period and equipment installation period of the project is 18 months.

Factors affecting the construction period of the plant include earth-rock excavation,

construction of main workshop, office building and assorting facilities, equipment

installation, transport and piling of decoration materials and construction site cleaning.

5.1.1 Influencing factors of the construction period and control measures

5.5.1.1 Influencing factors of the construction period

(1) Noise

Noise during the construction period includes noise of construction machinery and

transport vehicle. Analogy analysis demonstrated that the noise value of the machines falls

between 75 and 115 dB (A). In most cases, mixed noise value is above 90dB (A),

negatively impacting the builders and surrounding environment.

(2) Raise dust

Dust mainly comes from rock excavation, filling, concrete blending, earth taking at

the stock ground, bulk cement work and vehicle transportation. Major pollutant is TSP.

Dust generated from earth-rock excavation, concrete blending, earth taking at the stock

ground and waste slag piling is discharged step by step. And raise dust and waste gas

generated from bulk cement work, vehicle transportation and operation of construction unit

is discharged linearly.

(3) Solid wastes

Solid wastes produced during construction include muck and gravel during earth

excavation, material consumed during transportation process, including dinas, concrete;

consumption and abandoning of building stones, ash and building materials during road

pavement and maintenance, and domestic waste of builders.

(4) Waste water

Industrial waste water includes dewater of foundation pit, alkaline waste water of



139

concrete blending and maintenance which are discharged step by step, and domestic

sewage of builders.

5.1.1.2 Control measures for impact during the construction period

In order to cut back on the impact on surrounding environment, the following control

measures are to be taken to minimize the negative impact.

(1) Noise control measures

Noise of construction machineries shall be controlled. Protective measures shall be

taken for builders with regard to uncontrollable noise. Means of transportation shall be

vehicles meeting acceptable noise requirement. The specific control measures include the

following:

Rationally arrange construction time: try to avoid simultaneous construction of a

large number of strong noise equipment when developing construction plan, avoid the time

when surrounding environment is sensitive to noise, reduce nighttime construction;

accelerate construction schedule and shorten the overall work period.

Reduce the sound level of equipment: adopt low noise equipment, reduce noise

through silencer of exhaust pipe and isolating vibrating parts of engine; repair and maintain

motive power machine, reduce the noise because of the vibration of easily untight parts;

immediately shut down idle equipment; transportation vehicles shall slow down on the site

and reduce whistling.

(2) Raise dust and waste gas control measures

Sprinkle water on the construction site at a fixed time every day to avoid floating

dust; sprinkle more water and do more sprinklings during high wind days.

Clean and wash transportation passage of the construction site in a timely fashion to

reduce raise dust when vehicle is moving.

Transportation vehicle shall be steered slowly or under limited rate in the

construction site to reduce the amount of raise dust.

Earth yard shall be rationally selected which shall not be at the upwind direction of



140

the living area of builders. Concrete mixer shall be placed inside the workshop and isolated

wall and wind blocking board shall be arranged. Falling cement and sand during mixture

shall be cleaned regularly; piled earth shall be cleaned and transported timely; vehicles

going out of the plant shall be covered with paulin to reduce scattering along road.

Avoid open-air piling of cement, sand, lime and other dusting raw materials.

Dusty materials to and from the construction site shall be covered with canvas and

shipped by vehicle with fan cover.

Builders shall be responsible for cleaning road before the construction site and

clean earth and building materials scattered in a timely fashion.

Take very seriously waste gas emission pollution as a result of fuel oil of

construction machineries and vehicles which shall use clean energy fuel meeting national

standard, install tail gas purifier to reduce the emission of exhaust emission.

(3) Solid waste control measures

When vehicle transports soil, try to avoid scattering of earth; wide off earth on the

wheels before putting out of the construction site to avoid scattering of earth and affect

environment cleanness.

Construction waste shall be placed at designated site, cleaned and disposed timely.

Builders shall do a good job in professional ethics education on drivers who shall transport

materials on required routes while examining the plan implementation on an irregular basis.

MSW shall be recovered in a classified manner to ensure same day generation and

cleaning; littering is prohibited.

In case of finding harmful and hazardous wastes, construction shall be stopped

immediately. Builders shall contact local environmental watchdog and only continue

construction after taking measures.

(4) Waste water control measures

Builders and constructors shall value the management on construction sewage

discharge to avoid undisposed and unorgnaized discharge of sewage water and avoid



141

impact on environment after sewage emission. Major control measures include the

following:

Build site drainage to ensure foundation water is discharged orderly into

surrounding river.

Waste water of concrete blending and maintenance includes suspended matter,

silicate and oil type. A waste water desilter will be built to collect wastes which will be

reused instead of discharged after sedimentation and neutralized treatment.

Domestic sewage mainly includes SS, COD and animal or vegetable oil. Sewage

collection facility will be built in the temporary living area of builders. Feces and dirts will

be cleaned regularly and shipped outside as farmland compost.

Oil and chemicals shall be loaded and unloaded with closed container. Transportation

process shall be strictly managed to avoid transportation pollution. Builders shall

coordinate with transportation management authorities to transport equipment. Vehicles

shall be used rationally for centralized transportation to avoid peak time transportation and

reduce impact on traffic.

5.1.2 Analysis on environmental impact during the construction period

5.1.2.1 Noise impact analysis

Construction is always carried out in the open without sound insulation and reduction

measures, so noise is transmitted farther and affects a larger area. The sound level of various

construction stages falls between 75 and 115 dB (A). Major noise sources come from strong

sound construction machines and various construction stages witness the operation of several

machinery equipment. In addition, the sound level of stand-alone equipment is always higher

than 90dB (A). Together with changes in the location of equipment in the construction site,

and in the number of equipments under operation at different times of the same construction

stage, it’s hard to correctly predict the noise value of various boundaries of the plant.

Based on the projected conclusion of similar noise impact of machineries, the impact

range during day time is 60m and that in the nighttime is 180m. Since there are no residents

within 200 meters around the project site, so the project construction will not disturb

residents. Strong sound construction during nighttime is not allowed (no nighttime

construction during the piling stage is allowed). Day and night time construction shall do well



143

in taking protective measures. Construction noise shall strictly comply with the limit

requirement in Noise Emission Standard for Boundary of Industrial Enterprise

(GB12348-2008) to avoid negative impact on nearby residents.

5.1.2.2 Atmospheric impact analysis

Major source of atmospheric pollution is TSP. Surface structure is damaged during

ditching, pile laying and road pavement process and raise dust will pollute the environment.

Mound and earth-rock piled in the open also generate raise dust. In addition, increase in

transportation during the construction period also adds to the amount of raise dust along the

road. Earth-rock excavation and raise dust impose impact on local environment in the short

term, which may disappear when the construction is completed. Transportation raise dust

appears in 30m range on the two sides of the dust source road and is different depending on

roads. The TP of packway is 2-3times higher than cement road. Raise dust shall be sprinkled

with water regularly. As most of the nearby site of the project is open space and farmland, the

impact of raise dust isn’t very huge.

Secondary pollution source impacting atmospheric environment comes from waste gas

of construction machineries and transportation vehicles using diesel oil and gasoline. So tail

gas emission of construction vehicles shall meet relevant requirements. Due to short

construction period and small construction site, the waste gas pollution is localized and

temporary and will not expert impact on the surrounding environment.

5.1.2.3 Impact of solid waste on environment

Solid wastes of the construction mainly include domestic waste of builders, muck and

broken stone of earth excavation, materials consumed during material transportation process,

including dinas and concrete; losses and abandoning of building stones, ash and building

materials during road pavement and maintenance. As the project is basically constructed

within the plant boundary, solid waste generated is piled at designated site and management,

so there is slight impact on surrounding environment.

On top of that, soil fallen during transportation and soil on wheels will make the

highways filled with dirt. So builders shall pay attention to the disposal of mould on the road

and clear mould in a timely fashion.



144

Domestic waste generated during the construction period shall be cleaned timely and

collected by municipal environmental sanitary department.

5.1.2.4 Analysis on the impact on water environment

Foundation dewatering of the project is mainly underground and water is discharged via

open channel into nearby river; waste water of concrete blending and maintenance is

collected in a concentrated manner and will not be discharged outside after sediment and

neutralized treatment; Sewage collection facility will be built in the temporary living area of

builders. Feces and dirts will be cleaned regularly and shipped outside as farmland compost.

The amount of waste water discharged outside during the construction period is very small,

imposing little negative impact on the surrounding surface water environment.

5.1.2.5 Analysis on the impact of ecological environment

The planned construction site of the project is mainly farmland covering an area of

0.066667km2. According to Guidelines for Environmental Impact Assessment – Ecological

Impact (HJ19-2011), the assessment on ecological impact is Grade 3, so the assessment only

makes a brief comment.

5.1.2.5.1 Analysis on the impact of ecological environment

According to the basic process of engineering construction, heavy excavation

construction technology is adopted on the basis of leveling the construction plant during the

initial period to excavate the foundation of main workshop, stack, incineration equipment and

other major facilities. Based on the construction experience of similar projects, construction

activity imposes multiple negative impacts on the environment and ecology of the plant area,

including biodiversity, vegetation cover, land use, water and soil loss during the construction

period. But the most severe impact is the vegetation deterioration, and exacerbated water and

soil loss.

(1) Analysis on the loss of biomass

The planned project will damage the original vegetation during the construction process.

The planned project covers an area of 66667m2, mainly farmland.

(2) Analysis on water and soil loss



145

The surface soil will be destroyed during the construction period and earth and stone

excavated from the foundation may lead to water and soil loss during the temporary piling

process. Loose soil temporarily piled around the structures will trigger water erosion during

precipitation, especially torrential rain, leading to severe water and soil erosion; dried loose

soil may generate wind erosion, soil particles will be carried away in case of high wind,

leading to soil erosion. Excavated soil will easily fall during the transportation process, and

form thick dust layers after repeated grinding. Dust will blow during wind time, triggering

severe air pollution and affecting normal production and life of builders.

Type of water and soil loss

Precipitation during the flood season of the assessment area accounts about 2/3 of the

yearly precipitation, showing concentrated and strong rains. Major external agent leading to

water and soil loss is precipitation when the original surface isn’t damaged or under new

topography as a result of construction activity. The type of water and soil loss is water erosion

whose major forms include splash erosion, surface erosion and liner erosion. During the dry

and windy spring, the type of water and soil loss is wind erosion

Features of water and soil erosion

After the construction is started, the vegetation cover of surface will be totally peeled off

and damaged. Except that a small area is covered by buildings (structures) of the living area,

most of the plant is exposed. When it comes to the foundation excavation process, foundation

ditch soil and temporary waste soil as a result of foundation excavation of main workshop

and other facilities must be piled at designated place, forming a temporary reshaped

geomorphology with larger side. All of these may trigger water and soil loss.

Precipitation of the area mainly happens in the summer. The amount of rain during the

three months of summer accounts for 2/3 of the total, the plant area without vegetation cover

will surely be subject to water and soil loss if without viable protective measures during

windy or rainy days, exerting negative impact on local ecology. In this case, the construction

of the plant area will disrupt the vegetation cover and exacerbate water and soil erosion.



146

Water and soil loss hazards

Foundation excavation and other activity add to the slope of the original terrain, change

the surface structure, so the water solidification and water conservation capacity is weakened.

Without slope protection, the open and loose side may be subject to soil erosion in case of

stronger rainfall and high wind.

If concentrated rainfall or strong rainstorm happens during the flood season, it’s more

likely to worsen soil erosion, lead to channel blockade, and exacerbate water and soil loss,

which not only affects water delivery via channel, but also deals a heavy blow to the local

ecology and environment and heavy impacts the production and lives of surrounding

residents.

A large amount of water and rock would be excavated during the construction process,

which destroys original vegetation, changes original landform and disturbs surface. 66667m2

of original landform, land and vegetation will be disturbed and destroyed by the project. The

prediction of possible water and soil loss of the project is based on method of empirical

formula. The computation formula is as follows:

Soil erosion of surface disturbance:

iii TMFW

Where, W1 – surface erosion (t);

Fi – erosion area (km2);

M – module of soil erosion (t/km2·a);

Ti – time interval of construction (a).

According to the weather and soil feature of the project location, project disturbance

method, and analysis result of status quo of soil erosion, and by referring to the standard of

environmental impact assessment of relevant projects and research results, the project

provides corresponding probable value of module of soil erosion based on different

construction contents. The excavation value is 4200t/km2·a. The natural erosion module of

the project location is 2100t/km2·a.

560t water and soil will be lost during the construction period (about 18 months), or 560t



147

every year, almost 2 times of the status quo of water and soil erosion (140t). If water and soil

protective measures can be taken during the construction period, the probably value of

module of soil erosion may be 1.2 times of natural erosion module and the water and soil loss

is 336t/a.

5.1.2.5.2 Ecological protection measures

The most important ecological problems during the project construction period is water

and soil erosion, so priority shall be given to the prevention and treatment of water and soil

loss.

(1) Provention and treatment target

To reduce and control water and soil loss by taking both engineering and biological

measures based on the guiding ideology of “prevention first, all-round planning,

locality-oriented, integrated prevention and treatment, efficiency valued and tightened

management, with the aim of preserving water and soil and improving ecological

environment, and in line with the principle of “developers protect, and influencers pay”.

(2) Prevention and treatment task

According to the Law of the People’s Republic of China on Water and Soil Conservation,

construction projects shall do well in water and soil loss prevention and treatment: prevent

and cure water and soil loss in the expropriated, rent and administrative area and protect land

and water resources during the production process; minimize the damage to vegetation,

provide dedicated storage yard for waste soil and rock and take blocking measures;

excavation, discharge and filling yards shall undergo slope and land renovation; bare land

generated from development shall be restored with vegetation cover

(3) Preventative measures system

Engineering measures

Based on the realities of the planned project, the following works shall be done: build

retaining wall and drainage ditch in the outskirts of the site with huge earth excavation and

filling; try to reduce the disturbance to site if the change in terrain isn’t required by the



148

project to cut back on damage to original vegetation; try to restore vegetation cover to bare

land, build grassing plant case, and brick, water seepage “L” shaped floor tile; afforest side

slopes within and without the site

Land reclamation project

The assessment area is cultivated land before the construction; “three supplies and one

leveling” method shall be combined to reduce the soil bareness time and minimize the water

and soil loss. Upon completion, mechanized and manual methods shall be used to clean the

topsoil, remove gravel in the soil, construction waste and other sundries to the disadvantage

of tree and greenery growth, then plant grasses and trees to restore the water and soil

conservation function of the earth’s surface.

Recycling of earth for growing

Preferable earth for growing will be transported to the green area and effective

maintenance and management are needed during the construction period to put an end to dust

emission, soil erosion, and provide necessary for future greenery, which can not only save

investment, cut back on water and soil erosion. And the earth can also be reutilized, basically

meeting the demand for land of plant.

Control construction land use and plan vehicles into and out of the plant area

Construction organization design shall be compiled before the construction according to

national construction code. Construction land use shall be strictly controlled to minimize

damage to surface land. In the meantime, the scheme shall also plan well vehicles into and

out of the plant area, avoid unnecessary grinding of soil and damaging vegetation growth.

5.1.3 Summary

Construction activities of various kinds produce noise, waste water, raise dust and solid

waste during the construction period, leading to short term and partial impact on surrounding

environment. Pollution control measures shall be taken so as to minimize the impact on

surrounding environment.

5.2.2 Ambient air impact forecast assessment

5.2.2.1 Forecast mode and parameters

1. Forecast mode

The forecast adopts AERMOD (steady-state plume model), and it can simulate

short-term (hourly average, daily average) and long-term (annual average) concentration

distribution of pollutants discharged from point source, surface source and body source

based on atmospheric boundary layer data characteristics, which is applicable for rural areas

or cities with simple or complex terrains. The mode can simulate concentration distribution

within one hour or longer than one hour by utilizing hourly continuous pre-processed

meterological data, so it is applicable for grade one and two assessment projects with the

assessment scope of no more than 50km.

2. Meterological condition selection and the corresponding parameters

Meterological condition selection

Routine ground meterological data in 2011 of Pizhou Observatory Station is used for

calculation by day and by times.

Parameter calculation

In this project, grid point is set at 2500km away from stack, and the interval between

grids is taken as 50m.

3. Source intensity parameters

According to the engineering analysis, Table 5.2-8 lists the project point source discharge

parameters under normal and abnormal working conditions. See Table 5.2-9 for the project

surface source emission parameters. Based on investigation, the Pizhou Biomass Power

Generation Project of National Bio Energy Group is under construction to the west of the

project site. Please refer to Table 5.2-10 for source emission parameters.

5.2.2.2 Forecast scenario and forecast source intensity

(1) Forecast scenario

Based on engineering analysis and surrounding pollution source analysis of the project,

waste gas pollution source under normal working conditions of the project mainly come

from incinerators, and organized emission of solidification workshop, as well as unorganized

emission of waste storage workshop, waste percolate disposal station and ammonia water

storage tank. Waste gas pollution sources under abnormal working conditions come from

incinerators. The forecast scenario combination of atmospheric environmental impact is

5.2.3 Analysis on the forecast result of environmental air quality under normal working

conditions

(1) Forecast on the impact on unorganized foul gas emission under normal production

Analysis on target hitting at the plant boundary

The routine meteorological data of Pizhou in 2011 is used to calculate the impact of

unorganized foul gas emission. The forecast results are shown in Table 5.2-12. It

demonstrated that the maximum concentration of H2S and NH3 at the project boundary is

evidently lower than Grade 2 standard for newly renovated and expanded project in the

standard value of foul gas pollutants at plant boundary specified in Odor Pollutants Emission

Standard (GB14554-93). The maximum concentration of NH3 and H2S appears inside of the

plant boundary. The concentration of NH3 and H2S outside of the plant boundary meets the

environmental quality standard.

(2) Forecast of maximum concentration of major pollutants of the assessment area

The contribution value of pollutants of the project in the assessment area and protection

target is calculated by hour and by day based on the yearly meteorological data of Pizhou in

2011. The largest environmental impact and analysis of the assessment scope and protection

target are shown in Table 5.2-13, Table 5.2-14 and Table 5.2-15. The layout of concentration

isoline corresponding to largest contribution value of hourly, daily and yearly concentration

of NO2 is shown in Fig. 5.2-6 to Fig. 5.2-8; the layout of concentration isoline corresponding

to largest contribution value of hourly, daily and yearly concentration of SO2 is shown in Fig.

5.2-9 to Fig. 5.2-11; the layout of concentration isoline corresponding to largest contribution

value of hourly, daily and yearly concentration of PM10 is shown in Fig. 5.2-12 to Fig.

5.2-13; the layout of yearly concentration isoline of dioxin is shown in Fig. 5.2-14.

The Tables indicated that the average maximum hourly and daily concentration of

major pollutants of the project within the assessment range - SO2, NO2 and HCl – reaches

the standard after background concentration is overlaid; the average maximum daily

concentration of PM10, Hg, Pb and Cd reaches the standard after background concentration is

overlaid; the average maximum yearly concentration contribution value of SO2, NO2, PM10

and dioxin meet standard.

(3) Forecast of maximum concentration of protection targets

We can find from Table 5.2-14 and Table 5.2-15 that the average maximum hourly

concentration of protection targets SO2, NO2, CO and hydrogen chloride, as well as the



163

average maximum yearly concentration of dioxin appears in Xinchang, and the average

maximum daily concentration of PM10, Hg, Pb, Cd and the average maximum hourly

concentration of NH3 and H2S appears in Qufang Village. The maximum contribution of

hourly, daily or yearly concentration of various pollutants is lower than the limit value of the

assessment standard. The concentration of SO2, NO2, HCl, PM10, Hg, Pb and Cd meets the

standard after overlaying background concentration; the maximum impact contribution value

is far lower than the limit value of the assessment standard.

5.2.4 Forecast of environmental air impact under abnormal working conditions

5.2.4.1 Forecast of the impact of abnormal pollutant emission in case of fault of waste gas

disposal device (plan 1), and start (stop) of incinerator (plan 2)

According to The Notice on Strengthening Management on Environmental Impact

Assessment on Biomass Power Generation Projects (H. F. [2008] No. 82), the assessment

standard of dioxin accident risk refers to the daily surmountable intake of 4pgTEQ/kg and

the acceptable intake through aspiration is implemented by 10% of daily surmountable

intake.

If calculated as per 60kg of the average weight of every healthy adult, the limit value of

hourly acceptable intake through aspiration is 1pgTEQ/person/h.

Relevant data showed that the minute ventilation of average person at quiet time is

0.0042m3, and the hourly ventilation is 0.252m

3. The limit value of dioxin concentration

through aspiration is 3.97pgTEQ/m3. From Table 8.1-12, we can find that the maximum

hourly ground level concentration of dioxin under is lower than the limit standard in case of

an accident.

Based on the calculation results, the average hourly maximum concentration of the

assessment scope and protection targets is shown in Table 5.2-16 and Table 5.2-17. The

averagely hourly maximum concentration of major protection targets and ground

concentration overlay are specified in Table 5.2-18.

It showed that the abnormal emission of dioxins and hydrogen chloride exerts greater

impact on the outside environment than under normal working condition, but they all meet

the corresponding standard requirement; it has less impact on the downtown Pizhou, and the

predicted concentration is obviously lower than environmental quality standard value of the

functional area.

5.2.4.2 Analysis on impact of foul gas emission under abnormal conditions such as blowing

out repair (working condition 3)

Engineering analysis indicated that there are three reasons, making foul odor pollution

prevention measures unusable and invalid: when incinerator is shut down, primary air fan

stops drawing gas from the waste tank, air curtain device is subject to fault and stops

operating, waste tank is damaged in a large scale and isn’t enclosed any more. The first one

exerts the largest impact, happening one or two times at most every year and lasting 2-4 days.

Accident draught fan will be used to discharge gas of the waste pit (foul gas) to the air via

stack. When 2 incinerators are stopped (no foul gas of the waste gas is drawn for auxiliary

combustion), accident draught fan draws foul gas of the waste pit and discharges the foul gas

via exhaust funnel after deodorization by the deodorization device, which reduces the impact

on surrounding environment and maintains the waste tank enclosed. The emission

concentration of NH3 and H2S are 0.158mg/m3 and 0.015mg/m

3 respectively, which are far

lower than the emission standard, and the organized emission of NH3 and H2S will have less



179

impact on the surrounding environment, and its impact on the main protection targets meets

assessment standard.

5.2.5Analysis on the environmental impact of foul gas

Waste would be stored for 3-5 days before incineration to ensure normal operation of

the waste incineration plant, dehydrate part of the waste and increase heat value. Hydrothion,

mercaptan and other asphyxiant foul gas and toxic substance would be generated when the

waste is piled.

People can smell out more than 4000 malodorous substances via sense of smell,

including 40-plus substances affecting ecological environment and human health. Major

components of foul gas generated from MSW are sulfide and lower aliphatic amine. Foul gas

stimulates people’s sense organs, making people feel unpleased and disgusting. Hydrogen

sulfide, mercaptan, amine, ammonia and other components impose severe impact on

respiratory system, endocrinium system, circulatory system and nervous system. Long term

exposure to the stimulation of one or more low concentration odorants will trigger smell

fatigue and loss and other impediments, and even exciting and suppressive maladjustment of

regulatory function of cerebral cortex.

Foul gas generated in garbage power plant mainly comes from waste unloading

platform (including waste tank), waste delivery belt and sewage treatment station. According

to the survey on local residents about the flue gas of incineration, the impact of foul gas is

small. After high temperature combustion, the foul gas intensity of ash is smaller. With

regard to waste warehouse, as incinerator primarily supplies air and utilizes air in the

warehouse and the sewage treatment station, there is negative pressure in the warehouse, so

the distribution of foul gas is small. Waste foul gas is serious when incinerator is stopped for

overhaul. During waste incinerator overhaul, foul gas will be emitted after meeting certain

standards after being absorbed by activated carbon, thus reducing its impact on the

surrounding environemt.

The distribution of foul gas has something to do with weather. In case of clear and dry

weather, foul gas intensity is smaller, with smaller impact; but under rainy, low temperature

and high humidity conditions, the foul gas intensity and impact becomes larger.



180

5.2.6Environmental protection distance

NH3, H2S and odor pollutants during the project operation process mainly come from

waste storage workshop. The entire waste warehouse is enclosed structure and adopts

negative pressure environment, ensuring no outflow of bad smell. Gas in the storage tank

will be drawn from the top of the waste storage pit and sent to the incinerator after

preheating as primary air for combustion supporting, so as to control the emission of foul gas.

But foul gas will out flow when the gate of waste warehouse is opened during unloading,

under incomplete air draft and accidents. Survey on waste incineration system of similar

plants demonstrated that there is peculiar smell distributing in the plant area and along the

boundary. Under some working conditions (vehicles entering and leaving the waste

warehouse, blowing out for overhaul), the smell is thick, so certain protection distance must

be set for the garbage power plant.

Protection distance of atmospheric environment

Protection distance of atmospheric environment: set outside of the project boundary to

protection human health, reduce the impact of atmospheric pollutant on residential

community under normal emission conditions.

The protection distance of various unorganized source atmospheric environment is

calculated based on the mode as recommended in Guidelines for Environmental Impact

Assessment – Atmospheric Environment (HJ2.2-2008). Waste warehouse and sewage

treatment station of the project have the protection distances calculated respectively. Table

5.2-19 lists calculation parameters and the result.

Pizhou Observatory Station). Based on calculation of foul gas emission under normal

condition by taking foul gas control measure (Table 5.2-20), the maximum protection

distance shall not exceed 50m.

Calculated values of sanitary protection zone of NH3 and H2S generated in waste pit

and waste unloading hall are 0.774m and 1.68m respectively; calculated values of sanitary

protection zone of NH3 and H2S generated in sewage treatment station are 6.464m and

3.686m respectively; calculated values of sanitary protection zone of NH3 generated in

ammonia water storage tank is 6.603m. A 100m sanitary protection zone shall be set in the

waste warehouse and percolate disposal station; the sanitary protection zone of the ammonia

water storage tank shall be 50m.

H. F. [2008] No. 82 Document

According to H. F. [2008] No. 82 document, the environmental protection zone of the

project shall be no less than 300m. Based on the calculation result of atmospheric

environment protection zone and width of sanitary protection zone and H. F. [2008] No. 82

document, the farthest distance is used as the environmental protection zone of the project.

Please refer to Fig. 5.2-17.



183

We can find from Fig. 5.2-17 that waste warehouse and percolate disposal station of the

project shall set 100m width of sanitary protection area. And the figure for ammonia water

storage tank area shall be 50m. This is within the 300m range outside of the plant boundary.

As a result, the final environmental protection zone of the project is 300m outside of the

plant boundary. At present, there are no environmentally sensitive protection targets within

the 300m protection zone. There are 31 temporary houses in the southwest side of the plant

site (the north of Hongqi Community), and one old couple now live in it. The temporary

housing is temporary transition occupancy for Hongqi Community demolition. Currently, the

relocation housing is put into overall operation, and the temporary housing will be

dismantled before the end of December 2013. See Attachment 12 for details.

Land within the environmental protection zone shall not be used to build settlements,

schools, hospitals and other sensitive targets, and food processing, drug, cosmetics and other

projects with demanding requirement for air quality.

5. 2.7 Stack height demonstration

Stack height during waste incineration process not only matters a lot to the investment

of construction fund, but more importantly, the transmission range of flue gas and ground

concentration of pollutants after waste incineration.

The planned stack height is 80m, meeting the requirement in Standard for Controlling

Pollution from Municipal Solid Waste Incineration (GB18485-2001).

The height of buildings within 200m radius of the stack is ≤40m and stack is 40m

higher than the buildings, meeting the requirement that “5m higher than buildings within 200

radius”.

The Technical Guidance for Domestic waste Disposal stipulates for that “the stack of

incinerator with more than 300t/d of handling capacity shall be no less than 60m. When there

are structures within 200m radius of the stack, the stack must be 3m higher than the highest

building.” The stack height of the project meets relevant requirements.

In addition, based on the atmospheric environmental impact forecast result, the impact

of 80m high stack on the atmospheric environment within the assessment area meets relevant



184

standard.

So it’s rational that the project builds 80m high stack.

5.2.8Summary

(1) Forecast of environmental impact of unorganized discharged foul gas

The meteorological data of Pizhou in 2011 is used to calculate the impact of

unorganized discharged foul gas. Please refer to Table 5.2-10 for the forecast result. The

Table indicated that the maximum concentration of H2S and NH3 at the boundary is much

lower than Grade 2 standard for newly renovated and expanded project in the standard value

of foul gas pollutants at plant boundary specified in Odor Pollutants Emission Standard

(GB14554-93). The maximum concentration of NH3 and H2S appears within the plant

boundary. The concentration of NH3 and H2S outside the plant boundary meets the

environmental quality standard.

(2) Forecast and analysis on impact on ambient air under normal working conditions

The contribution value of pollutants of the project in the assessment area and protection

target is calculated by hour and by day based on the yearly meteorological data of Pizhou in

2011. The average maximum hourly and daily concentration of major pollutants of the

project within the assessment range - SO2, NO2 and HCl – reaches the standard after

background concentration is overlaid; the average maximum daily concentration of PM10,

Hg, Pb and Cd reaches the standard after background concentration is overlaid; the average

maximum yearly concentration value of SO2, NO2, PM10 and dioxin meets the standard.

The average maximum hourly concentration of protection targets SO2, NO2, CO and

hydrogen chloride, as well as the average maximum yearly concentration of dioxin appears

in Xinchang, and the average maximum daily concentration of PM10, Hg, Pb, Cd and the

average maximum hourly concentration of NH3 and H2S appears in Qufang Village. The

maximum contribution of hourly, daily or yearly concentration of various pollutants is lower

than the limit value of the assessment standard. The concentration of SO2, NO2, HCl, PM10,

Hg, Pb and Cd meets the standard after overlaying background concentration.

(3) Environmental protection zone



185

It’s required that 300m environmental protection zone shall be set outside of the project

boundary. Please refer to Fig. 5.2-17 for the sketch map. At present, there are no

environmentally sensitive protection targets within the 300m protection zone. There are 31

temporary houses in the southwest side of the plant site (the north of Hongqi Community),

and one old couple now live in it. The temporary housing is temporary transition occupancy

for Hongqi Community demolition. Currently, the relocation housing is put into overall

operation, and the temporary housing will be dismantled before the end of December, 2013.

Land within the environmental protection zone shall not be used to build settlements, schools,

hospitals and other sensitive targets, and food processing, drug, cosmetics and other projects

with demanding requirement for air quality.

(4) Forecast of environmental air impact under abnormal working conditions

The average hourly concentration of hydrogen chloride under abnormal working

condition is lower than the standard and it’s projected that at this moment, dioxin inhaled by

ordinary adult in the protection area is lower than the acceptable intake, thus meeting the

requirement of “H. F. [2008] No. 82 Document”. The impact of abnormal working condition

on surrounding environment and sensitive targets is higher than normal working conditions.

Therefore, mangement shall be tightened and effective measures shall be taken to

ensure normal operation of waste gas treatment facilities; in case of ignition, shut down or if

furnace temperature fails to meet requirements due to other reasons, raise temperature by

injecting diesel to support combustion and reduce generation of dioxin.

5.3Water environmental impact analysis

The project shall be equipped with self-built percolate disposal facility. Once such

pre-treated high concentration waste water as waste percolate and other waste water reach

take over standard, they will be connected to Daixu Sewage Treatment Plant through sewage

pipe network. After meeting Grade IA standard as specified in Discharge Standard of

Pollutants for Municipal Wastewater Treatment Plant, waste water treated in the Daixu

Sewage Treatment Plant, tail water will be introduced into tail water diversion channel in

Xuzhou section of South-to-North water diversion project the through special pipe network,



186

instead of being discharged into the surrounding water body like Beijing-Hangzhou Canal.

According to analysis on pollution control measure in the report, high concentration

waste water in this project can meet take over standard requirement of Daixu Sewage

Treatment Plant in Pizhou.

Based on environmental impact statement on Daixu Sewage Treatment Plant in Pizhou,

after Daixu Sewage Treatment Plant is put into operation, tail water under normal discharge

condition will have less impact on the diversion project water quality and no impact on the

Beijing-Hangzhou Canal.

5.4 Acoustic Environmental Impact Assessment

5.4.1 Noise sources

Noises of the proposed project mainly include noise of machinery equipment, air power

noise and noise of transportation device. Strong noise equipment of the project includes

turbo generator unit, gas fan, draught fan, blender, steam emission of boiler and cooling

tower.

Major strong noise source turboset is set within a main workshop, making the workshop

a dimensional noise source. Integrated consideration is necessary to predict based on surface

source. Cooling tower produces stable, continuous and low frequency noise and the noise of

steam emission of boiler is high frequency and intermittent noise source which could be

110dB(A) during operating. It exerts great impact on surrounding impact and transmits

farther.

Major acoustic equipment and noise level of the project is shown in Table 3.6-6.

5.4.2Forecast of acoustic environmental impact

The forecast mode is the model recommended by Guidelines for Environmental Impact

Assessment – Acoustic Environment (HJ2.4-2009) which will be simplified if necessary

during the application process.

use the sound barrier decrement formula:

A ｒ 10 ｇ 3 20N

N 2δ

δ SO OP—SP is the path different (see the picture blow),

is the wave length of sound wave.

When the predication point is far from the noise source, sound decrement as a result of

air, ground and vegetation absorption shall be taken into consideration:

A ｔｒｒ 100

Where, a is the decrement factor. It’s dereference is linked with specific environmental

status, which is about 1-2dB(A)/100m.

(2) Prediction results

The calculation mode is simplified based on the features of the project and existing

data. In order to fully estimate the impact of noise source on surrounding environment, petty

positive decrement which doesn’t meet calculation condition may be ignored to calculate

sound level of various prediction sites. The prediction results are specified in Table 5.4-1.

We can find from Table 5.4-1 and Table 5.4-2 that the noise predication value of

various prediction sites after Pizhou Biomass Power Generation Project of National Bio

Energy Group is overlaid can meet Type 2 requirement in Noise Emission Standard for

Boundary of Industrial Enterprise (GB12348-2008).

The isogram of noise contribution, day time noise prediction value, night time noise

prediction value are shown in Fig. 5.4-1, Fig. 5.4-2 and Fig. 5.4-3 respectively.

5.4.3 Assessment standard

Noise emission standard within the boundary of the planned project is based on Type 2

standard of Noise Emission Standard for Boundary of Industrial Enterprise

(GB12348-2008).

5.4.4 Assessment result

The assessment showed that noise at various points within the boundary upon the

project is completed can meet the standard. Noise at various points within the boundary after

Pizhou Biomass Power Generation Project of National Bio Energy Group is overlaid can still

meet Type 2 standard. There are no environmentally sensitive targets within 20m outside of

the project boundary. So there won’t be noise disturbing residents when the project is

completed.

5.5 Prediction and Assessment on the Impact on Underground Water

Environment

5.5.1 Hydrogeologic introduction of the study area

5.5.1.1 Type of underground water and distribution

Underground water of Xuzhou is divided into three major types: pore water, karstic

water and fissure water, the corresponding storage media are pore aquifer of loose rock,



196

karstic aquifer of carbonatite and aquifer of clastic rock. The underground water type within

the impact scope of the project belongs to quaternary pore water, dynamic type of the

underground water is penetration - evaporation flow, with the main supply source from side

run off supply and meteoric water penetration, discharged way include evaporation,

underground run off and manual extraction underground water.

Fissure water has poor water yield property, pore water is mainly recharged by

atmospheric precipitation infiltration, and supported by infiltration recharge of Yellow River

and downstream water. Carbonate rocks exposure zone in the area can be divided into low

mountain hill karst area and plain hidden-karst area based on different burial conditions of

carbonate rock stratum and aquifer structure. In the low mountain hill karst area, carbonate

rocks directly outcrop the surface or the quaternary system is thin, there is direct hydraulic

connection between the quaternary system pore water and karstic underground water, and

karstic underground water can directly recharged by atmospheric precipitation infiltration, so

it belongs to Karst bare type or Karst connected type, karstic water belongs to water. The

plain hidden-karst area is covered by a unconsolidated formation of 30 to 80m thick, and the

bottom of the quaternary system (middle pleistocene) has dense and hard plastic clay pan,

carbonate rock stratum is scattered, with complex water-bearing structure and karstic

underground water can not be directly recharged by precipitation infiltration, so it belongs to

leakage and run off type, and karstic water belongs to confined water.

5.5.1.2 Underground water regime and supply relation

The main water enrichment rock in the project site include stratum silty clay, stratum

silty clay, stratum -1 silt and stratum moderate sand as well as stratum -1 silt

and stratum -2 moderate sand in the form of lenticle.

The investigation is conducted during dry season, burial depth of stable underground

water level is between 1.10m and 1.20m, and the corresponding elevation is between 21.60m

and 21.50m. According to local hydrological and meteorological conditions, the

underground water level is mainly affected by seasons, with the maximum level reaching the

earth surface during wet season (rainy season) and amplitude of variatio nof around 1.20m.



197

zone. It has poor watery and water permeability. Water-bearing stratum in the study area

mainly include pore water and stratum 2 confined water; average thickness of the

5.5.3.2 Rule of dynamic changes of underground water level of the study area

Long-term underground water level observation wells include three monitoring wells in

Tongshan District of Xuzhou. Underground water level of the monitoring well is observed

every 5 days. The curve of underground water changes from 2010 to 2012 is shown in Fig.

5.5-1. We can find from the figure that underground water level remains high between June

and November each year and remains low in other month.



201

Fig. 5.5-1 Curve of Dynamic Changes of Shallow Underground Water Level of Xuzhou

5.5.3.3 Supply-run off-drainage relationship of underground water

The underground water supply comes from vertical and lateral supply. Vertical supply

mainly stems from infiltration of meteoric water and the average precipitation is 867.8mm/a

as the main supply source for underground water. The relationship between underground

water level and precipitation is closely and the underground water level increases along

increase in precipitation and drops along decrease in precipitation.

Drainage method includes evaporation. Meterological data showed that the water

surface evaporation is 1210.5mm/a, but the evaporation of underground water is closely

linked with the burial depth of underground water level and the burial depth of underground

water level of the study area is 1.1-1.2m. The amount of evaporation has something to do

with the limit depth of evaporation. The figure is 5m in the study. When the depth exceeds

5m, the impact of evaporation may be ignored. In addition, the actual underground water

evaporation is much smaller than water surface evaporation. The second drainage method is

pump water from water source area, with pump output per well is about 1200m3/

d.

According to Guidelines for Environmental Impact Assessment – Underground Water



202

Environment (HJ610-2011), the status quo observation of underground water arranged 12

drill holes in the plant site and surrounding area which monitored the status quo of

underground water level of the drill holes, and identified the location and underground water

level of every well (Table 5.5-2).

According to the underground water level of observation holes, we got the underground

water flow field figure (Fig. 5.5-2) of the entire assessment area from which we can find that

higher water level appears in one side of Gonghu River (mainly in the northeast of Hezhuang

Village) and the water level in west and north part is lower (Fig. 5.5-3). The drainage mainly

includes evaporation and artificial water taking.

5.5.4 Survey and assessment on environmental geological conditions

5.5.4.1 Survey and analysis on regional pollution sources

Field visit and survey showed that some villagers are located in the surrounding area of

the project location, without evident pollution discharge sign. Water source site is located in

the north side of the project location, and there are no plants and enterprises. So possible

pollution source in the area is percolate in the waste landfill.

5.5.4.2 Status quo of underground water pollution

There are 5 underground water quality monitoring points in project location and the

surrounding area. Water quality monitoring factors include water temperature, pH, Cr6+,

ammonia nitrogen, As, Pb, Cd, total fecal escherichia coli, Hg, nitrate nitrogen and nitrite

nitrogen. Please refer to chapter 4.3.2 for details. We can learn from the table that heavy

metal content is low while the content of other factors is high, but all of these factors satisfy



206

type III water quality requirement.

The concentration contour map of ammonia nitrogen and potassium permanganate

index in underground water of the study area is drawn based on the measured underground

water quality indicators (background value) (Fig. 5.5-4). From the Figure, we can find that

ammonia nitrogen concentration near Xinchang is higher while that near Hezhuang

Village is lower; potassium permanganate index near Shizhuang Village is higher while

that near the project site is lower.

(a) Ammonia nitrogen



207

(b) Potassium permanganate index

Fig. 5.5-4 Concentration Contour Map of Major Pollutants of the Study Area

5.5.4.3 Major pollution assessment factors

Major pollutants of waste water of the project include COD, BOD5, SS, NH3-N, TP and

trace elements Hg, Cd, Cr, Pb and Ni. Data of underground water quality supervision

indicated that the amount of trace elements in underground water is low which may not be

the major assessment factors; in addition, SS and TP are easily absorbed by the soil in

aeration zone before entering underground water. So small amount of them enter

underground water and they may not be major assessment factors. Major assessment factors

cover COD and ammonia nitrogen. Despite of high content of COD in earth’s surface,

experimental data reflected that the content of COD in underground water is low and

consumed by organisms along the route. So we replace it with potassium permanganate



208

index whose content may reflect the size of organic pollutants in underground water. The

concentration of COD is 300mg/L and years of data accumulation showed that COD is

always 3-5 times of potassium permanganate index, so the ceiling limit value of potassium

permanganate index is taken in simulated prediction, the concentration is 150mg/L. The

concentration of ammonia nitrogen is 35mg/L.

5.5.5 Prediction and assessment of underground water environmental impact

5.5.5.1 Prediction method

The study adopts numerical method to simulate the water flow and pollutant migration

in the study area and FEFLOW (Finite Element Subsurface Flow System) software is

applied. The numerical simulation software was developed by Germany WASY (water

resource plan and system research institute) at the end of 1λ70s. It’s one of the underground

water simulation software packages with the most complete functions by now and defined by

rapid and precise numerical method and advanced image visualization technology.

Major applied fields include: simulate underground water flow field, underground water

resource planning and management scheme; simulate the impact of open or underground

extraction in mineral area on regional underground water and optimized countermeasures

plan; simulate sea water of deep saline invasion issue triggered by underground water

excavation near the coast or underground water drainage in mineral area; simulate

underground water flow and temperature distribution in non-saturated zone and saturated

zone; simulate the migration process of pollutants in underground water and time, space

distribution rule (analyze and review the impact of industrial pollutants and urban waste

storage on underground water resources and ecological environment, and study on optimized

countermeasures and plans); simulate “precipitation – surface water – underground water”

resource system combining precipitation – run off model, analyze interdependence of

various components of the water resource system, study on rational water resource

utilization and plan for the impact plan of ecological environment protection.



209

5.5.5.2 Conceptual model of hydrogeology

Conceptual model of hydrogeology is to scientifically summarize and process

hydrogeological conditions based on a comprehensive analysis of underground water system,

including geography, actual boundary conditions of aquifer, internal structure, permeability,

hydraulic characterstics, and supply and drainage, so as to generalize the complicated

hydrogeological body, which will help for mathematical or physical simulation. In this case,

when building conceptual model of hydrogeology, the following aspects shall be taken into

consideration: the generalized model shall be equipped with the function of reflecting the

prototype of hydrogeology of the study area; the generalized boundary conditions shall

comply with the features of underground water flow field; generalized model boundary shall

try to utilize natural boundary; the manual determination of boundary features shall consider

from unfavorable factors.

The east, south and west sides of the study area are generalized as the type 1 boundary,

or water head boundary; the northern boundary is type 2 boundary. The bottom of

unconfined aquifer is water proof boundary. As a result, we get the conceptual model of

hydrogeology (Fig. 5.5-5).

5.5.5.4 Deference of model parameters

(1) Determination of specific yield

The specific yield of unconfined aquifier has something to do with the lithology of

aeration zone, and changes alongside changes in drainage time, burial depth of phreatic



212

water, variation range of water level and water quality. The empirical value of various

lithologies is shown in Table 5.5-3. The lithology of the study area is silty clay and clay, so

the deference of specific yield of the study is 0.03.

(2) Determination of porosity

The size of porosity of rock and soil is linked with the arrangement type, size of

particles, sorted behavior, shape of particles and glue degree. The porosity of various

lithologies is shown in Table 5.5-4. The lithology of the study area is mainly silty clay and

clay, so the porosity of the study is dereferenced at 0.45.

(3) Determination of osmotic coefficient

The main lithology of the study area is silty clay and clay, and see Table 5.5-1 for

dereference of osmotic coefficient.

(4) Determination of feed coefficient of precipitation infiltration and rainfall infiltration

The feed coefficient of precipitation infiltration means the ratio between

precipitation infiltration volume and the total precipitation, is dependent on the lithology

of the earth surface stratum, stratum structure, gradient, vegetation coverage and volume and

form of precipitation, and it is a dimensionless coefficient varying between 0 and 1. See

Table 5.5-5 for feed coefficient of precipitation infiltration under different precipitation

volume and lithology conditions.Since the average annual precipitation in the study area is

867.8mm, with main lithology of clay, so is taken as 0.12.

(5) Determination of phreatic water evaporation coefficient and phreatic water evaporation

Phreatic water evaporation coefficient is mainly related to annual water surface

evaporation, lithology and burial depth of underground water level. Please refer to Table

5.5-6. The annual water surface evaporation is 1210.5mm, the burial depth of underground

water level is 1.1-1.2m and major lithology is clay, so the d ereference of evaporation

coefficient is 0.08.

Phreatic evaporation is mainly related to the burial depth of phreatic water level,

lithology of aeration zone, land vegetation, weather and other factors. According to previous

research results, we believe that the phreatic water evaporation in region with more than 5m

of burial depth of water level is very small (Table 5.5-7).

Table 5.5.-7 Limit Burial Depth of Phreatic Water Evaporation of Different Lithologies

(6) Determination of dispersity

The project is located in Xuzhou, so we carried out field dispersion test in Kuihe

River area (Fig. 5.5-6), based on this, we calculated dispersity of silty clay (clay) by

taking into account scale effect of diversity (Fig. 5.5-7). According to the indoor

dispersity experiment, and the dereference of vertical dispersity and horizontal dispersity

of the unconfined aquifer within the assessment scope is 50m and 5m respectively.

5.5.5.5 Initial and boundary conditions

(1) Regional disperse

The computational area takes the central area of the project location as the origin of

coordinates, true north direction is the forward direction of y axis, and true east direction is

the forward direction of x axis, pure vertical is the forward direction of z axis. We consider 4

layers of pure vertical, 7216 nodes of disperse and 8243 units. Please refer to Fig. 5.5-8 for

subdivision map of the study area.

Fig. 5.5-8 Subdivision Map of the Study Area

(2) Initial and boundary conditions

Boundary conditions: the study area is a relatively independent hydrogeological unit.

The northwest side is type 2 boundary condition and other boundaries are type 1 boundary

conditions. The bottom of aquifer is water proof boundary. The roof receives precipitation

supply. The drainage is mainly through evaporation and pump.

Initial conditions: the water level of monitor wells is taken as the initial water level of

simulated predication, the background value of pollutants observed by the monitoring well is

the initial value. The initial time is June 2012.

Source sink term: the daily discharge of waste water under normal conditions is 149m3,



218

according to the equation in D.1 appendix table of Guidelines for Environmental Impact

Assessment – Underground Water Environment (HJ610-2011), the vertical infiltration

coefficient is 0.01, based on this, we can work out the daily infiltration of waste water of

the project location is 1.5m3, in case of emergencies, we assume 30% of waste water

infiltration is discharged, that is, 45m3/d.

5.5.5.6 Working condition calculation during operation period

According to the schedule, the project construction lasts for about 18 months. In view

of short term construction, domestic sewage and water used for machines, there won’t be

impact on underground water. So this research only takes into consideration the impact of

percolate, industrial waste water and domestic sewage generated during the operation period

of garbage power plant on underground water. The model calculation considers the following

working conditions: (1) the construction project is operated normally, and by taking into

consideration the project location and the surrounding underground water flow field and

pollutant transport rule, the forecast time is 20 years. (2) In case of an accident, part of

anti-seepage measures do not work, flow of waste water penetrated into underground water

becomes larger. Based on 30% of the total amount, the forecast time is 100 days (around

0.27 years), and see Table 5.5-8 for simple list of working condition calculation.

5.5.5.7 Analysis on simulated prediction results

(1) Analysis on seepage field

By using the underground water level monitored in June 2012, the simulation results

showed that the underground water level at the waste water seepage place witnessed a small

increased, but the increase range was rather limited near the waste water tank. Compared

with no waste water infiltration, water level increased by 0.2m (Fig. 5.5-9), up by 0.01m



219

every year. In case of accidents, waste water infiltration reached 45m3/d, up by 0.58m in 100

days, higher than the water level increased in 20 years under normal conditions. It showed

that the impact on underground water seepage field under accidents is larger within small

range surrounding the waste waster seepage place. The above analysis indicated that waste

water infiltration will lead to increase in part of underground water level, but it’s within a

small range of the project location. Under normal conditions, the range of water level

increase is small. Water level increases rapidly in case of accidents.

(2) Analysis on pollutant migration

Pollutant migration mainly takes into consideration potassium permanganate index and

ammonia nitrogen pollution factors. The migration features under normal and accident

conditions are shown in Table 5.5-9.

Note: Line 0.27 year (100 days) in the Table indicates the simulated result of accidents, Line 1, 5, 10 and

(a) Potassium permanganate index

The concentration of potassium permanganate index at the pollutant source place is

maintained at 150mg/L. Judging from the plane, the maximum migration distance of

pollutant source at the project location 10 years later is about 55m (Table 5.5-9). The

concentration of pollutants will increase and the diffusion range of pollutants will be further

as time goes by (Fig. 5.5-10 and Fig. 5.5-11). If looking at from the impact range of

pollutants is 3-5m, the simulation proved that the diffusion of pollutants in vertical direction

is slow. This is mainly because the waste water emission of the study area is small, the

variation range of underground water level is small and the pollutants are unlikely to diffuse.

Due to precipitation and waste water infiltration, underground water level increases slightly,

but the migration of pollutants is mainly via molecular diffusion. In addition, the study area

is mainly composed of claypan with small permeability, so the pollutant diffusion is slow. In

case of emergencies, the waste water infiltration increases to 45m3/d, which is farther than

the pollutant migration range in 1 year under normal conditions (Table 5.5-9). It



222

demonstrated that pollutants in underground water can expand to a large area in case of

accidents.

(b) Ammonia nitrogen

The concentration of ammonia nitrogen at the pollutant source place is maintained at

35mg/L. Judging from the plane, the maximum migration distance of pollutant source at the

project location 10 years later is about 43m (Table 5.5-9), which is smaller than the

maximum distance of potassium permanganate index migration because the higher

concentration of potassium permanganate index source. The concentration of pollutants will

increase and the diffusion range of pollutants will be further as time goes by (Fig. 5.5-12 and

Fig. 5.5-13). If looking at from the impact range of pollutants is 6-8m. In case of

emergencies, the waste water infiltration increases to 45m3/d, which is farther than the

pollutant migration range in 1 year under normal conditions (Table 5.5-9). It demonstrated

that pollutants in underground water can expand to a large area in case of accidents (Fig.

5.5-14).

The above analysis indicated that the pollutant migration range and range of exceeding

the standard are small in either plane or profile. This can be attributed to two reasons: first,



227

underground water flow field controlled the pollutant migration; from hydrogeological units,

the project location is within the drainage area of underground water, so it’s difficult for

pollutants to migrate with water flow; second, the stratum of the study area is mainly silty

clay with small permeability and strong absorption power, so pollutants migrate slowly in

the area.



228

5.5.5.8 The impact of pollutant migration on water resource area

There is water source area around the project site, with a total of ten wells. This

underground water assessment area involves seven of them (Fig. 2.4-3), of which, 10# well

is 530m away from the pollution source, the nearest one.

The analysis is carried out from several aspects, including geomorphology, lithology,

geologic structure, hydrogeological conditions, and simulated predication results of

pollutants.

Geomorphology: the project site is flat, with less underground water level difference, so

the underground water flow rate is slow, mainly adopting vertical supply and drainage;

atmospheric precipitation serves as the main supply source, drainage is realized mainly

through evaporation and supported by artificial pump. Such water supply, run off and

drainage method makes it hard for pollutants to diffuse to the surrounding area of the project

site, thus it has less impact on wet land.

Lithology: geological exploration and regional stratum data indicated that the

thickness variation of loose stratum of the study area is 30m and the lithology is mainly

silty clay and clay with low permeability. The pollutants migrate slowly in the medium.

The absorption power and self-purification capacity are strong. Together with sound

seepage-proofing measures at the place storing waste water, in fact, pollutants entering

underground water are very small.

Geologic structure: there is no clear major dislocation from the project site, the regional

stability is strong. Waste water leakage as a result of the role of geologic structure is unlikely

to take place, so it will have less impact on water quality of the water resource area.

Hydrogeological conditions: major types of underground water of the study area include

phreatic water and confined water. Geological exploration data indicated that there are three

stratums of clay and two stratums of moderate sand, with average depth of the clay stratum

of 5m and average depth of moderate sand of 4m; due to small permeability of clay stratum

and slow pollutants migration rate, the connection between two aquifers is weak. Mainly



229

unconfined aquifer has close connection with pollutants. So there will not be impact on

confined water and water quality of the conservation area.

Simulated predication results of pollutants showed that the overproof range of

pollutants will be 4298m2 and the maximum migration range is 74m after 20 years operation

of the project. Pollutants are basically controlled within the project site, with little impact on

surrounding environment. 10# pump well is 530m away from the project site, which is much

larger than the maximum migration range of pollutants. So the waste water of the planned

garbage power plant will not cause pollution to the water resource area.

5.5.6 Brief summary

5.5.6.1 Conclusion

(1) According to Guidelines for Environmental Impact Assessment – Underground

Water Environment (HJ610-2011), the planned project is Grade I project, the grade of

underground water environment impact assessment is Grade III and the size of the

assessment region is 45.5km2.

(2) The calculation results of pollutant source intensity indicated that the pollution load

ratio of waste percolate reaches 99.97%, which are key area for pollution prevention and

treatment and major pollution sources of underground water. Combined with the load ratio

and status quo of underground water quality survey, the pollutant assessment factors are

ammonia nitrogen and permanganate index.

(3) Assessment on hydrogeological conditions: the types of underground water of the

assessment area is defined as hole phreatic water based on filed study, water level monitoring

and geological exploration data. The annual dynamic variation range of underground water is

very small. Underground water mainly receives precipitation supply, runs off to the project

site and low lying region and discharges from evaporation and manual extraction.

(4) Status quo assessment of underground water environment: 5 water quality

monitoring sites are set up in the project site and surrounding area to know the underground

water quality condition of the project site and surrounding area. The underground water



230

quality around the project site is good and free from nitrogen pollution, it meets Type IIII

standard requirement in Underground Water Quality Standard (GB/T14848-93) and is

unsuitable for drinking. So the water quality will not have impact on human health.

(5) Prediction of underground water environmental impact

The simulated prediction results of water flow showed that waste water infiltration

will lead to increase in part of underground water level within a small area of the project site.

Under normal conditions, the range of underground water level increase as a result of waste

water infiltration is very small. The water level increases rapidly in case of accidents. The

hydraulic gradient increases and the diffusion speed of pollutants is rapid.

The simulated prediction results of pollutants (permanganate index and NH3) showed

that the maximum migration distance of pollutants in horizontal direction in the project site

20 years later is about 74m; the distance in vertical direction is 6-8m, showing that the range

of vertical diffusion of pollutants is much smaller than the range in horizontal direction. This

is because the osmotic coefficient in vertical direction is smaller than that in horizontal

direction. Generally speaking, pollutants migrate slowly in underground water, with almost

no impact on underground water in surrounding environment (villages and water resource

area). High concentration pollutants mainly appear in underground water within small area

of the waste water discharge place of the project site.

In case of accidents, underground water level increases rapidly, the hydraulic gradient

increases, the pollutant diffusion range increases rapidly within short term. At the same time,

the concentration of pollutants in surrounding area of the project site also increases rapidly.

Therefore, accidents shall be handled immediately to avoid the expansion of the impact

range of pollutants.

The diffusion range of pollutants is mainly related to stratum structure, permeability,

hydrogeological conditions, waste water infiltration, and background value of certain

pollutant concentration. Among others, stratum structure, permeability and hydrogeological

conditions are major factors. The stratum of the study area is mainly silty clay, with small



231

permeability and strong absorption power. Pollutants migrate slowly in the area.

5.5.6.2 Suggestions

(1) Although the pollutant emission does not exert impact on surrounding villages and

water resource conservation area. For security reason, builders are suggested to arrange

monitoring well in the north side of the project site or the surrounding area during the project

construction and operation process, so as to determine the range of pollutant diffusion into

pump well defensive line and concentration and protect water quality of water resource area.

(2) The pollutant diffusion range has something to do the amount of waste water

infiltration, so when building waste water tank, builders shall enhance the seepage proofing

function of waste water tank to reduce the infiltration of waste water in sewage pool and

effectively control pollutants from entering underground water.

5.6 Analysis of impact on soil

In the solid waste generated in the project, content of such harmful substances as heavy

metal and organic matter is high, so if no waste stack place is arranged or no proper

anti-leakage measure is taken, harmful components will generate high temperature and toxic

liquid which will seep into soil after weathering, rainwater leaching and surface water run off,

kill microorganism in the soil, damage the balance between the microorganism and the

surrounding environment, leading to no trees and grass and crop output reduction in a large

area. Meanwhile, water permeated into underground water through soil can also pollute the

underground water quality. Therefore, solid waste generated in the project must be properly

stored and handled with.

The exhaust gas generated by the project during its operation period is typically the

smoke generated from incineration that contains trace heavy metal and dioxin that may

subside into the surface soil of surrounding evaluation areas. Heavy metals may accumulate

in soil, which will change physical-chemical properties of soil, lead to soil fertility

degradation and probably make heavy metals enter into the food chain via crops, and thus



232

affect people’s health. Dioxin-like organics could be decomposed in a few days after the

settlement on soil if they are exposed to the sunlight. But dioxin-like organics are likely to

contaminate the soil if they settle into the soil because their half-life period is more than 10

years. The project is set with flue treatment workshop and stringent flue control measure is

taken to ease the impact of flue on the soil environment.

In this project, multiple layers of anti-seepage materials are set at the bottom of waste

tank, percolate tank bottom and side wall, thus the pollution of soil caused by waste

percolate can be minimized.

5.7 Eco-environmental Impact Analysis

(1) Impact of local regional climate

The project site is now farmland, part of the land will be hardened by using cement and

part will be manually greened after the project is completed. Due to small thermal capacity

and large reflectivity, evaporation heat consumption is almost zero; the lower pad surface has

high temperature and quick temperature increase rate, thus forming a "heat wave band", all

of these will change small environment of the construction site and deteriorate local micro

climate. Since land occupation in this project is less compared with the whole large area, it

will have very small impact on the whole climate.

(2) Impact on vegetation

Vegetation within the project location are mainly artificial vegetation like farmland. The

impact of the project on the plant resources are mainly demonstrated in low vegetation

coverage rate locally due to project land occupation and reducing biomass. However, its

impact on the unit area biomass in the whole area is not large, and will not cause loss of plant

species.

(3) Impact on agricultural plants

Pollutants generated during waste incineration and emission mainly include dust, SO2,

NO2 and other atmospheric pollutants. Atmospheric pollutants intrude or adhere to leaves

and damage lamina organization and its normal function, weaken photosynthesis, and affect



233

growth and output. Due that various atmospheric pollutants emitted from waste incineration

have combined actions on plants, for instance, joint action of SO2 and nitrogen oxides will

cause more damage on plants than single gas.

Pollutant emission volume will be reduced greatly after flue going through half-dry

treatment, and together with the adoption of 80m high stack, ground level concentration of

pollutants is lower, thus waste gas emitted after meeting certain standards will have less

impact on the surrounding agricultural crops.

5.8 Analysis of Waste Transportation Influence and Recommended Practices

5.8.1 Transport volume analysis

The transport volume analysis of the project is as follows:

Transport into the project site

Domestic waste: 600t/d

Transport out from the project site

Fly ash 22.1t/d

Slag 149.9 t/d

Total: 772t/d

Transport vehicle and volume analysis

Domestic waste: the transport vehicle adopts 8t breech-loading compression refuse

collector; small transfer station is equipped with 5t and 8t van vehicle in the near term and 8t

van vehicle in the middle and long ter. Carrying capacity of 5t van vehicle is 3.5t/set, 6t/set

for 8t van vehicle. Domestic waste transportation: about 63 vehicle times per day.

Fly ash: 8t cover automatically sealed vehicle. Carrying capacity is 6t/set, about 4

vehicle times per day.

Slag: 10 cover-sealed truck is adopted. Carrying capacity is 8t/set, about 10 vehicle

times per day.

Domestic vehicle: about 4 vehicle times

Total: 90 vehicle times per day

If we calculate based on 8 hours, and assume that 70% of transport tasks can be



234

completed in 4 hours during peak hour, hourly peak traffic volume is 16 vehicle times per

hour, or one vehicle time every 3.8 minutes in average.

5.8.4 Analysis of garbage transportation impact and proposed measures

Waste transportation routes are defined by wide roads and good traffic performance. But

sensitive targets are concentrated in urban sections as on both sides of roads there are mainly

commercial, office and residential complex. In order to alleviate urban traffic pressure, preset



238

transportation time may be taken into consideration, such as increasing transportation density

at night. Based on current transportation routes, the transportation conditions for this project

can be guaranteed.

What on both sides of the transportation routes of the project are commercial,

residential and office buildings and waste leachate in case of leakage will generate stink odor.

In this case, construction units must pay enough attention to the waste transportation process,

improve the sealing performance of refuse vehicles, keep an eye on the check and

maintenance of these vehicles and eliminate leakage trucks so as to protect city appearance

and sanitary environment.

(1) Noise effect

The noise source of refuse carrier vehicles is about 85dB(A). Under the circumstances

without any obstacles, the calculated equivalent continuous sound level is 69dB(A) 6 meters

away from both sides of the roads. That means the traffic noise 6 meters away from both

sides of the road accessing to the plant meets the requirement that the equivalent continuous

sound level on both sides of arterial traffic at daytime must be lower than 70dB(A). But, the

noise at night is above the standard level of 55dB(A). The equivalent continuous sound level

is 55dB(A) in areas 30 meters away from the roads. It’s thus clear that the traffic noise in

areas 30 meters away from the road accessing to the plant meets the requirement that the

equivalent continuous sound level on both sides of arterial traffic at both daytime and night

must be lower than the standard value of 55dB(A). The office and residential complex within

30 meters from both sides of the roads may feel the impact of traffic noise.

(2) Stink and environmental and sanitation impact

Protein of animals and plants in the natural world can create odor pollutants during the

process of bacterial decomposition. Smells of hydrogen sulfide, ammonia and methanthiol

generated from the dump and storage of refuge make people feel uncomfortable.

Wastes will have compressing treatment before transportation and will be transported

by fully sealed garbage trucks. The leakage of stinks, wastes and leachate from trucks will be

controlled during the transportation process. On top of that, the transportation volume of the

project is rather huge and the haul distance is quite long, so garbage leaked is likely to



239

generate stinks once a traffic accident occurs during the transportation process and thus

affects local environment and sanitation.

(3) Wastewater influence

When the sealing performance is good, the leakage of refuge leachate from garbage

trucks will be effectively controlled during the transportation process and will have little

impact on the quality of water on both sides of roads along the way. That said, in the event of

the leakage of wastewater from transportation trucks along the way, the water body nearby

will be polluted after rain scouring.

(4) Measures on preventing environmental pollution along garbage transportation

routes

As part of the effort to mitigate the transportation impact along the way, the following

measures are suggested:

Using sealed carrier vehicles with wastewater seepage storage tank to load and transport

refuge; strengthening vehicle maintenance and repair; replacing old vehicles with new ones

on a timely basis in a bid to guarantee a strong sealing performance;

Carrying out periodic cleaning of transportation vehicles; doing a good job in the

cleaning of roads and on both sides of the roads;

Shortening the stopping time of vehicles near sensitive points as much as possible;

refraining from building new office and residential buildings and other sensitive complex on

both sides of the road accessing the plant;

Equipping each vehicle with necessary means of communication for emergency contact;

transportation workers must inform competent departments as soon as possible for proper

treatment once an accident occurs during the transportation process;

Enhancing ideological education and technical training for drivers to avoid road

accidents;

Preventing transportation noise at night that will disturb local residents;

Adopting informatization management means for transportation vehicles; reinforcing

the tracking and supervision of waste carrier vehicles; establishing an information

management base for transportation trucks; implementing the information feedback system



240

for measuring control and rubbish transportation.

6 Social Impact Analysis

6.1 Social Impact Analysis on Demolition and Relocation

There are no environmentally sensitive protection targets such as residents within the

300m protection zone. There are 31 temporary houses in the southwest side of the plant site

(the north of Hongqi Community), and one old couple now live in it. The temprorary

housing is temporary transition occupancy for Hongqi Community demolition. Currently,

the relocation housing is put into overall operation, and the temperoray housing will be

dismantled before the end of December 2013.

Since the 31 AHs moved into the new community in the end of 2008, there is no

person living there. In fact, these houses should have been demolished by the end of 2008 as

they were built on the cultivated land which is not permitted. This is a special case approved

by the government in order to solve the transition for people. According to the survey, only

an elderly couple is raising livestock (only 10 chicken) here after the transition period. This

household has another house and a courtyard in Hongqi Community for stockbreeding,

which is 800 meters away.

The existing transmission lines and substations will be utilized. There is no need to

acquire new land.

6.2 Impact Analysis on Human landscape

The project construction will cause vegetation deterioration and water losses & soil

erosion, which will exert adverse effect on landscape. The project is designed with a green

space of 19030m2, or green coverage ratio of 29.5%. As greening improves, the project will

be in harmony with its surrounding environment and its impact on landscape environment

will be decreased constantly.

6.3 Impact Analysis on Population Health

Based on feasibility analysis on the project pollution prevention and control measures

and various special environmental impact analysis, treatment measures for waste gas, waste



242

water, solid waste and noise are rational and feasible, with less impact on the environment

during the project operation period.

The project is set with an 300-meter environmental protection distance outside of the

plant boundary. There are no environmental sensitive protection targets within the 300m

scope.

In summary, the project will have less impact on social environment where it locates if

sound pollution prevention and environmental management measures are taken.

6.4 Positive effect of Waste Incineration for Power Generation

Waste represents one of the important pollution sources threatening ecological

environment and human health, if piled up at will without taking effective treatment

measures, waste will seriously affect and damage the water environment, air environment

and soil environment, and even pose a direct threat on personal safety and health. As a public

welfare environmental protection project, the project has significant social benefits in the

following aspects:

(1) It settles environment pollution caused by waste and improves life quality of the

general public

In accordance with the “reduction, reutilization and reclamation" waste treatment policy

of China, waste incineration is a relatively feasible urban waste treatment method. In recent

years, waste incineration power plants have been built in many Chinese cities, and some of

which are operating well and have generated considerable environmental benefits. The

project conforms to Chinese waste treatment policy, firstly, weight of slag and fly ash only

account for 20% and 4.5% respectively of domestic waste after incineration, thus realizing

the requirement of waste reduction by large margin, and leaving out vast waste piling field.

Secondly, a vast number of harmful substances in waste will have less toxicity after being

incinerated in incinerator at a high temperature, thus reducing environmental pollution.

The common practice of waste disposal plants in Pizhou is simple, mainly adopting

landfill, with nearly saturated processing capacity and low sustainable development level.



243

Concentrated waste processing facilities are adopted in this project, with complete

professional technology, equipment and management ability as well as high professional

level and disposal condition, thus realizing better processing effect, saving operating cost

and disposal expense, and improving high pollution prevention level. The project will greatly

ease domestic waste absorption difficulty in Pizhou, realize the goal of waste "reducation,

reutilization and reclamation", effectively reduce waste pollution, improve urban living

environment and guarantee public health. Timely transport and incineration of urban waste

are critical for pubic health and life quality. The project is an important move to guarantee

health of Pizhou people, improve life quality, bring benefits to people and create a civilized

and hygienic city.

(2) It provides waste disposal method

At present, there is one domestic waste piling field in Pizhou, which is located at the

junction of Pisui Road and west road in the southwest of Pizhou. Process is simply piled,

without harmless treatment capacity. The Field was completed in 1994 and now is tending to

saturation. As economic & urban construction develops rapidly, domestic waste in Pizhou

keep growing and domestic waste disposal volume in Pizhou will reach 222400t/d by 2012,

but the existing landfill sites fail to dispose all the waste generated, so the project

construction is imperative.

Waste disposal capacity of a city reflects appearance and spirituality of the city. In

China, many environmental protection model cities and spiritual civilization cities are

developed from hygienic cities. Better urban hygienic environment, city appearance and

spirituality will improve investment environment of Pizhou, boost urban economic

development, attract more investment, promote development of tourism industry and other

tertiary industries and generate huge indirect economic benefits.

(3) It reduces waste land occupation and improves investment environment

Urban development causes increasing urban waste, and waste disposal site selection is

also limited. Waste incineration has such advantages as small land occupation, long service



244

life, significant waste reduction effect and complete harmless treatment. In particular, waste

incineration can save more precious land resources compared with sanitary landfill method

at a time when land resources are increasingly in short supply.

In this project, waste incineration volume is reduced, which will significantly decrease

waste disposal area, eliminate hidden danger of urban safety and social stability, and

improve urban infrastructure as soon as possible.

(3) It increases electric energy production and offer job opportunities

Annual on-grid energy of the project is designed as 68 million kWh, which will satisfy

local growing electricity demand to some extent, ease local power supply tension and

contribute to local socioeconomic growth. Besides, the project will offer job opportunities.

(4) Project evaluation

In a word, the project belongs to an environmental protection and public welfare project.

Waste incineration has such advantages as complete harmless-free treatment, significant

waste reduction and comprehensive utilization of waste heat and slag, and it is a good urban

domestic waste disposal method which can meet increasing urban waste disposal demand.

Therefore, the implementation of the project will bring about significant benefits to

sustainable social and economic development of Nanjing.

7 Environmental Risk Analysis

7.1 Purposes and Focus of Environmental Risk Assessment

(1) Purposes of environmental risk assessment

The purposes of the environmental risk assessment are to analyse and predict the impact

of leaked poisonous & harmful and flammable & explosive substances on personal safety

and environment and the damage degree, propose reasonable and feasible prevention,

emergency and mitigation measures so that accident rate, loss and environmental impact of

the project stand at an acceptable level. The leakage poisonous & harmful and flammable &

explosive substances are caused by potential dangers, harmful factors, as well as sudden

events or accidents occurred during the project construction and operation period (generally

excluding man-made destructions and natural disasters).

(2) Focus of environmental risk assessment

The environmental risk assessment will be focused on forecast and prevention of

damages to population outside of the plant (site) boundary and deterioration of environment

quality caused by accidents as well as its impact on ecological system. The environmental

risk assessment shall highlight the impact of accidents on the environment outside of the

plant (site) boundary.

248

The table above suggests that light diesel is flammable liquid, HCl, CO, NH3 and H2S

belong to general toxic dangerous substances, CO, NH3 and H2S combustible gases and

dioxin acute dangerous substance.

Major hazard installation identification

The substance to be stored and transported is light diesel, an inflammable and explosive

substance. Light diesel is characterized by high vapor pressure, high volatility, low flashing

point and wide explosion limit, so it tends to cause combustion and explosion in usual

environment. If not properly transported, stored, loaded and unloaded, light diesel might

cause leakage and detonation as a result of accident, cause great harm and serious

environment pollution, and bring about huge economic losses and casualties. Oil depot for

this project is installed with one 20m3 oil tanks with volume filling ratio of 0.85 and the

maximum storage of around 14.5 tons, and density is taken as 0.85g/cm3.

Light diesel, HCl, CO, NH3 and H2S are selected as identification factors in the project,

and refer to relevant regulations in Table 2 and 3 in Attachment of Guidelines for

Environmental Risk Assessment on Construction Projects (HJ/T169-2004) and Identification

of Major Hazard Installations for Dangerous Chemicals (GB 18218-2009). Table 7.2-3 lists

the major hazard installation identification results, which illustrates that oil depot of the

proposed project belongs to a major hazard installation.

7.3 Risk Identification

7.3.1 Dangerous material identification

Based on Attachment A (normative appendix) of Guidelines for Environmental Risk

Assessment on Construction Projects (HJ/T169-2004), toxic, flammable and explosive

substances involved in this project are light diesel, HCl, CO, NH3 and H2S. Diesel oil leaked

from the diesel storage tank will cause fire and even explosion accident in the presence of

open fire. Accidental emission of HCl, CO, NH3 and H2S will have certain impact on the

environment.

Leaked waste percolate will pollute underground water and soil.

7.3.1 Hazard analysis on main production processes

In accordance with engineering analysis, environmental risks during the production

process of the proposed project mainly cover four aspects, firstly, the supporting flue gas

treatment facility of incinerator has fault; secondly, in case of an accident, two incinerator

stop working simultaneously; thirdly, explosion accident caused by excessive CO amount in

the incinerator will have impact on the environment; fourthly, odor pollutants accidental

emission is occurred if odor prevention measure is not implemented normally.

7.4 Source term analysis

7.4.1 Accident source term analysis

Based on analysis, accident source terms of this project are as follows:



254

(1) The supporting flue gas treatment facility of the incinerator will have impact on the

surrounding environment if it fails to reach normal treatment efficiency;

(2) Malodorous gases emitted under abnormal conditions such as incinerator blown

out for overhaul will have impact on the surrounding environment;

(3) Fire and explosion risk due to leakage of light diesel from storage tank will have

impact on the surrounding environment;

(4) Explosion accident caused by excessive CO amount in the incinerator will have

impact on the surrounding environment;

(5) If odor prevention measure is not implemented normally, odor pollutants

accidental emission will have impact on the surrounding environment.

(6) Ammonia volatilized from leaking ammonia water storage tank will have impact on

the surrounding environment.

7.4.2 Maximum credible accident

According to design, two light diesel storage tanks with the maximum volume of 20m3

are provided, accident cofferdam is set around the tanks to retain diesel within the cofferdam

instead of entering into surface water environment in case of an accident. When the

incinerator is initiated or shut down, production control is unfavorable, incinerator

temperature is extremely low and CO content in flue gas is excessively high, while the

chance that both activated carbon adsorption device and flue gas purification bag filter can

not work normally is very slim.

In contrast, if the supporting flue gas treatment facility of incinerator fails to reach

normal treatment efficiency, excessive waste gases emission will cause air pollution and

even exert serious impact on the environment. Therefore, the fault that the supporting flue

gas treatment facility of the incinerator does not reach normal treatment efficiency is

determined as the maximum credible accident in this assessment. After referring to data and

making analogy analysis, the occurrence probability of such accident is 1×10-5

/a.



255

7.5 Accident Consequence Analysis

7.5.1 Atmospheric environment accident risk forecast and calculation under abnormal

condition

Atmospheric environment accident risk forecast and calculation under abnormal

condition cover two circumstances, firstly, waste gas is emitted as the supporting flue gas

treatment facility of incinerator fails to reach the normal treatment efficiency; secondly,

dioxin is emitted unusually during the process of incinerator startup (temperature rise) and

shut down (fire off) due to insufficient incinerator temperature, short retention time of flue

gas, or management or human factors. Please see section 5.2.4.1 for relevant forecast and

assessment.

7.5.2 Fire and explosion risk caused by diesel leakage

The most possible accident in oil depot is fire and explosion as a result of stored oil

leakage. Once the oil storage tank is on fire, radiant heat generated from burning oil will

affect on the surrounding tank or building, or even lead to another fire accident, thus exerting

a certain destructive effect on the surrounding environment.

Based on main risk factors and harmful factors analysis for this project, fire and

explosion risk assessment on oil tank is carried out as per Dow Chemical Fire and Explosion

Risk Index Assessment Method (7th

version).

Table 7.5-1 and 7.5-2 respectively calculate related indexes for each unit and safety

measures compensation coefficient based on the Dow Chemical Fire and Explosion Risk

Index Assessment Method. Risk grades of all units are listed in Table 7.5-4 by referring to

Dow Chemical Fire and Explosion Risk Index Grade Table (Table 7.5-3). Table 7.5-4

suggests that risk grade of each unit lowers by a grade after safety compensation, so fire and

explosion risk grade of oil tank in this project is "lighter" and within the acceptable scope;

impact scope is mainly within the plant area of the project.

Exposure radius can be obtained by referring to figure or through calculation based the

calculated fire and explosion index. Exposure radius and exposure area of each unit is

calculated and listed in Table 7.5-5.

7.5.3 Environmental impact analysis of odor pollutant accidental emission due to abnormal

implementation of odor pollutant prevention measures

Once an accident occurs, exhaust gas (stench) in the waste tank to upper air through

stack and by adopting emergency fan, turning unorganized emission into organized one and

reducing its impact on the surrounding environment. Beyond that, deodorant shall be

injected in waste tank to reduce odor generation as much as possible. Please refer to 5.2.4.2

for relevant forecast and assessment.

Therefore, constructor shall reinforce daily management and maintenance of supporting

activated carbon adsorption device of waste bin to ensure normal operation of the device in

case of an accident. Incinerator operation and maintenance shall also be strengthened to

prevent the four incinerators from stop working simultaneously; if the two incinerators stop

working at the same time, immediately use emergency fan and activated carbon adsorption

device to minimize the impact.



260

7.5.4 Environmental impact analysis of explosion accident due to excessive CO amount in

the incinerator

Generation concentration of CO in the incinerator is generally around 80mg/m3, and its

volume ratio is 6.74×10-5

, which is far lower than explosion limit of CO (v%) 12.5-74.2, so

no explosion accident will happen under normal circumstances. The probability of explosion

due to excessive CO amount is also very slim, as there is no report on this up to now. The

main reasons of excessive CO amount are: insufficient blowing rate of blowing fan (primary

and secondary air fans) leads to incomplete combustion and generation of a large amount of

CO, meanwhile, air exhaust volume of induced draft fan is not significantly improved, so

that a large amount of CO is concentrated in the furnace and waste heat boiler. The

probability of such situation is also very small for this project, and it will not last for a long

time, one hour at most; CO concentration then is far lower than the explosion limit (v%)

12.5-74.2, so explosion probability is very small; if explosion occurs, HCl and other

pollutants in the waste gases will be emitted into the surrounding environment, exerting

larger impact.

7.5.5 Environmental impact analysis of methane explosion accident

When all the three incinerators stop operating and when waste is stored in waster pit,

methane explosion accident might occur, but the chance is small. Actually, the possibility of

methane explosion in percolate collection chamber is larger. The occurrence of methane

explosion accident must meet two conditions: methane concentration is within its explosion

concentration range and there occurs combustion source in methane gas within its explosion

concentration range. The probability of such case is very small and can be completely

prevented by adopting precautionary measures.

7.5.6 Environmental impact analysis of ammonia water storage tank leakage

(1) Calculation of quality evaporation of ammonia water storage tank

Chemical leakage includes leakage of chemical in production equipment, excessive

storage tank pressure or heating may cause fusible plug melting and leakage or valve leakage



261

caused by mis-operation. In actual production process, due to limited feeding material,

leakage crack area of production facilities is generally small. In contrast, storage tank

leakage volume is larger, with the storage tank bottom leakage as the most serious situation.

In this assessment, we select the most serious case of storage tank bottom leakage as a basis

of chemical leakage volume.

Ammonia water storage tank volume in the proposed project is 10m3 and we calculate

quality evaporation rate of leaked ammonia Q3 based on the following formula:

Where:

Q3——quality evaporation rate, kg/s

a,n——Atmospheric stability coefficient; E-F stability conditions, n=0.3,

a=5.285×10-3

;

p——surface vapor pressure of liquid, Pa;

R——gas constant, J/mol·k;

T0——ambient temperaturek; it is taken as 288.4K here;

u——wind speed, m/s; it is taken as small static wind of 1.0m/s here;

r——liquid tank radius, m.

According to calculation, quality evaporation rate of leaked ammonia water (ammonia)

is 0.006kg/s, and it is assumed that accident will be handled with within ten minutes.

population health. The maximum concentration in the downwind direction in case of an

accident is 112.76mg/m3 which is far lower than 1390mg/m

Note: the concern point concentration is considered in the downwind direction.

When an accident happens, impact of ammonia on the sensitive points can still meet

the standard limit requirement. After the accident is finished, since pollution source has

stopped emitting pollutants, pollutant concentration will return to normal gradually.



265

However, impact of ammonia pollution will involve the plant area and the area around

pipeline in case of accidental emission of ammonia, so effective emergency measure must be

adopted and emergency plan launched so as to control pollutant emission volume and

continuous emission time, shorten pollution duration and ease its impact on the environment.

7.6 Accident Risk Precautionary Measures

7.6.1 Countermeasure of incinerator waste gas treatment system contamination accidental

emission risk

Special personnel responsible for daily environment management shall formulate

“Environmental Management Responsibilities” and “Environmental Pollution Prevention

and Control Measures” and strengthen supervision and management of incinerator waste gas

treatment facilities.

Periodic inspection and maintenance of the waste gas treatment facility and

equipment shall be reinforced, and hidden danger of accident shall be timely settled once

discovered.

Incinerated flue gas is equipped with automatic monitoring system for SO2, NOx,

CO, HCl, HF and smoke dust, and on-line monitoring of waste gas pollution control effect

shall be carried out.

Advanced and efficient waste gas control equipment and facilities shall be

introduced to ensure pollutant up-to-standard emission.

Carry out electric preheat bag-type dust remover until the required temperature is

reached, and start up incinerator and the bag-type dust remover simultaneously.

Light diesel shall be used to support combustion when the incinerator temperature is

relatively low; the incinerator temperature shall be 850℃ at least to avoid abnormal

emission of dioxin.

Centralized control shall be strengthened, distributed control system (DCS) shall be

adopted for centralized supervision and control of key devices of the main body; in case of

global or major fault of DCS, emergency blow out and shut down operation shall be carried



266

out; supervision and independent operation of system process and operation condition shall

be available in the centralized control room; communication or hard wire interface is adopted

to realize information exchange between DCS and systems such as waste and slag pit hoist

bucket, rotary atomizer control system, pneumatic and auxiliary burner control system,

bag-type dust remover control system, turbine digital electric hydraulic control system and

turbine emergency trip system.

Measures to reduce flue gas accidental emission

a. Half-dry injection acid-absorption system fault precautionary measure

Maintenance of atomizer motor and coupler of spray reaction tower shall be tightened

during production process to ensure their normal operation. Replace time shall be as short as

possible in case of fault to reduce the impact of the accidental emission on the environment.

b. Activated carbon injection system fault precautionary measure

During the incineration process, activated carbon injection system shall operate

normally to ensure absorption of heavy metals, dioxin, etc. The activated carbon injection

system can carry out automatic control and real-time monitoring; fans shall be maintained

during peace time to reduce the possibility of fan damage. Once the activated carbon

injection system has fault and the fan is damaged, timely replace spare parts and start up

standby fan. Activated carbon reaction layer is accumulated on the surface of successive

bag-type filter, so it can absorb heavy metals and dioxin; therefore, short-time fault of the

activated carbon injection system will not have great impact on heavy metals and dioxin

removal.

c. Bag-type dust remover leakage fault precautionary measure

When incinerators are blown out for overhaul, the bags will be replaced in batches as

per their using periods to ensure filter efficiency. During the operation, the on-line monitor

can detect leaked bag according to its concentration change, and examine one by one and

replace the leaked bag while not causing smoke dust emission exceeding standard.

Safety precautions for incineration flue gas treatment process shall be implemented.



267

Once the flue gas treatment system is abnormal, automatic alarm system will automatically

send alarm. Under this circumstance, no combustibles are allowed to enter into the

combustion furnace, the furnace enters into close procedure, and reducing valve of secondary

combustion chamber opened. Metal device shall be grounded to reduce fire caused by static

electricity. Temperature of combustion section of incinerator must meet process requirement

to ensure complete combustion of waste.

storage safety technical measures and follow Class B industrial design fire regulations and

norms.

Establish sound safety production responsibility system and carry out regular safety

inspection, and examine and repair regularly pipelines and valves of oil storage tank to

discover hidden dangers and eliminate them promptly.

Enhance safety consciousness and safety education, elevate personnel safety

awareness, carefully follow through safety laws & regulations and systems to avoid wrong

behavior and outline emergency measures.

Diesel storage tanks shall be a certain distance away from the incinerator.

prevent leaked material from entering into the rainwater system, and then cut off all leakage

sources as much as possible.

(4) In case of fire or explosion, firstly close rainwater discharge valve and plug all

gutter inlets which might be polluted; fire waste water shall be drained into fire water

collection tank; besides, pollutants such as CO and dust generated as a result of the fire

accident shall be injected by fire water to ease its impact on the environment, and all fire

water shall be drained into emergency tank.

7.6.4 Sewage accident precautionary measures

(1) Countermeasures of Inlet water pollution accident

In order to ensure stable operation of the sewage treatment engineering, sewage

discharge pipe shall be closed in case of waste percolate accidental discharge of waste

percolate, and directly drain the waste percolate into accident storage tank to prevent it from

causing shock load on Daixu Sewage Treatment Plant.

(2) Countermeasures of sewage treatment engineering accident

Improve accident buffering capacity

To restore normal operation of the sewage treatment engineering in case of accident,

main hydraulic structures must be reserved with sufficient buffer space, and the

corresponding treatment equipment (return pump, return piping, instruments and valves, etc.)

shall also be available.

If percolate treatment system in the plant fails to operate normally, waste percolate



269

generated will be firstly stored in accident tank. In this project, 500m3 adjusting tank (also

serving as accident tank) can store waste percolate water generated in 2 to 3 days, and it will

be discharged after being treated and meeting certain standard after the fault is cleared;

percolate accident collection tank shall have rational size.

which might cause accident.

7.6.5 Precautionary measure for explosion accident due to excessive CO amount in

incinerator

The following precautionary, mitigation and emergency measures shall be taken to

avoid explosion accident due to excessive CO amount in incinerator: (1) in case of

incomplete combustion based on monitoring of oxygen amount in the incinerator, timely

adjust combustion to allow complete combustion of waste; (2) induced draft fan and blower

shall be interlocked, once the induced draft fan has fault and stops work, the blower and

incinerator shall also be stopped; (3) observe negative pressure of the furnace to prevent

from positive pressure; (4) in case of incinerator blow out due to explosion accident in

incinerator, immediately stop air supply and exhaust air with induced draft fan for a longer

time; (5) do well daily repair and maintenance of the incinerator to avoid accidents.



270

7.6.6 Precautionary measure for methane explosion accident

Concentration monitoring instrument shall be set in waste tank and percolate

chamber to conduct real-time monitoring of methane concentration; when methane

concentration reaches a certain level, start exhaust fan to decrease the concentration;

Operation regulation on waste tank and percolate chamber shall be strictly followed

by, in particular, no combustion source is allowed to occur in the waste tank; if it is

necessary to carry out welding operations in the waste tank and percolate chamber which

might generate spark flame, firstly start up accident exhaust fan to lower methane

concentration to a certain level;

Special air supply and exhaust system shall be set in the percolate chamber, and

7.8 Summary

Toxic, flammable and explosive substances involved in this project include light diesel,

HCl, CO, NH3 and H2S. Environment risks during the production process of the proposed

project mainly include: firstly, fault of the supporting flue gas treatment facility of the

incinerator; secondly, all the two incinerators stop working in case of an accident; thirdly,

explosion accident due to excessive CO amount in the incinerator has impact on the

surrounding environment.

Accident cofferdam is set around the light diesel storage tank to ensure that diesel in

these tanks will not be leaked out of the cofferdam in case of an accident, nor will it enter

into surface water environment. The flue gas treatment facility fault accident forecast results

suggest that, under accidental emission situation, pollutants like dioxins will exert more

impact on the surrounding environment than normal conditions, but it is lower than daily



276

tolerable intake of human body 4pgTEQ/kg, allowable intake through inhalation shall be

10% of the daily tolerable intake, meeting the relevant assessment standard. Under accidental

status, malodorous gas will be emitted through 80m high stack after being absorbed by

activated carbon, with less total emission volume and less impact on the surrounding

environment.

The project management shall be intensified, various accident risk prevention measures

proposed in the report shall be strictly followed through, accident emergency plan shall be

formulated, thus avoiding occurence and development of accidents and preventing local

environment from being polluted.

In a word, after the project is completed, its risk level is acceptable if the

environment risk prevention measures are taken.



277

8. Pollution Prevention & Control Measures and Technical & Economic Feasibility

Demonstration

8.1 Waste Water Treatment Measure

Water drainage system for this project is adopted with water-sewage separation system.

The waste water of the proposed project is mainly waste percolate and cleaning wastewater

and domestic sewage. The waste percolate and cleaning wastewater produced in this project

shall be drained into Daiwei sewage treatment station of Pizhou together with the domestic

sewage to be treated after being collected and treated in the self-built percolate treatment

station till they are compliant with the influent requirement.

8.1.1 In-plant Pretreatment Measures

(1) Waste Percolate Treatment Process

Waste percolate produced in this project shall not be directly sprayed back to the

incinerator, because if the waste percolate is directly sprayed back to the incinerator, the

furnace box temperature will be reduced, which will not only cause insufficient burning of

garbage, but also produce large amounts of dioxin; otherwise, auxiliary fuel must be added,

which will not only increase conventional energy losses, but also increase the operating

expenses. The waste percolate shall be drained into Daiwei sewage treatment station of

Pizhou after being compliant with the influent requirement of Daiwei sewage treatment

station of Pizhou through pretreatment. The “pretreatment + UASB + MBR biochemical

treatment” treatment process is adopted in the percolate treatment station. The treatment

process is shown in Figure 8.1-1.



278

Figure 8.1-1 Waste Percolate Treatment Process Flow

Description on the treatment process:

The waste percolate in the garbage pit shall be drained into the percolate collecting tank

in the main plant, and the discharge hall and garbage channel cleaning water shall also be

discharged into the collecting tank, then drained into the percolate regulating pool through

pumps. Effective volume of the regulating pool is 2500m3.

Sewage in the regulating pool is drained into the pretreatment system which is

composed of mixed reaction pond, sedimentation tank and discharged water heating pool

after being elevated through basket filter by pumps. Main functions of the pretreatment

system are to dose coagulant, to remove part of the suspended solids, COD and BOD, so as

to reduce the load of subsequent processing; the heating tank is added with some steam to

regulate anaerobic water inlet temperature to make it comply with the requirements of

anaerobic reaction.

Pretreated effluent is drained into the bottom of the UASB reactor after being elevated

by pumps through the water distributor. The effluent flows from bottom to top at a certain

flow rate. When it gets through the suspended sludge layer and granular sludge layer to get

sufficient contacts with the anaerobic sludge, organic matters are adsorbed and decomposed;

and the biogas thus produced is discharged via the gas collecting chamber of the three-phase



279

separator at the upper of UASB, the effluent containing suspended sludge enters the

depression area of the three-phase separator, sludge with good sedimentation properties

returns to the main part of the reactor through the sedimentation surface, and the sewage

containing a small amount of lighter sludge is discharged from the upper part of reactor.

The anaerobic reactor can granulate the sludge within the reactor, and has good

sedimentation properties and higher methanogenic activity. Sludge in the reactor is of higher

concentration and longer age, which greatly improves the COD capacity load, and achieves

good contacts between the sludge and water. Due to the adoption of high COD load, the

biogas production is high, so that the sludge is under the expanding and fluidizing state, mass

transfer effect is enhanced, and the purpose of sufficient contact between sludge and water is

achieved. Sludge at the sludge bed is mainly micro-particle sludge and flocculent sludge, two

UASB reactors are set. Effluent treated through the anaerobic reactor shall be drained into

the MBR system for further treatment.

MBR reactor is composed of the A/O reaction tank and UF system. In the A/O tank, the

high-efficient jet aeration system is adopted, the oxygen utilization rate can be as high as

25%, in the O tank, through highly active aerobic microbial action, it can degrade most of

the organic matters, and oxidize the ammonia and organic nitrogen into nitrate and nitrite to

backflow to the front A tank and to be discharged after being reduced to nitrogen under

oxygen-deficient environment, so as to achieve the purpose of denitrification. The MBR

reactor separates the purified water and thallus through the ultrafiltration membrane.

Backflow of sludge can make the sludge concentration in the biochemical reactor reach

15g/L, and microbial flora produced through constant domestication can also gradually

degrade part of the non-biodegradable organics in the percolate. In this dump, BOD/COD of

the percolate pit = 0.5, which means the biodegradability is good, the designed COD removal

rate is 96%, and ammonia nitrogen removal rate is 99%.

Effluent of the A/O tank is drained into the ultra-filtration system through the

ultra-filtration water inlet pump. For the ultra-filtration treatment process of this project,



280

ultra-filtration membrane with membrane hole diameter of 0.02-0.05 m is adopted, in which

the inner and outer surfaces are dense layer densely covered with micro holes, and the

middle part is the multi-hole support layer. Purified water is separated from the thallus

through the ultra-filtration membrane, ultra-filtrated concentrate carries the activated sludge

to directly return to the A/O system at the front end. Because the relative retention time of

the refractory organics in the biochemical processing system is extended, the

microorganisms are effectively domesticated, and part of the refractory organics can also be

transformed into biodegradable ingredients. The remaining sludge is discharged back to the

sludge thickening tank.

Various indicators of the effluent of MBR have reached the standards, and completely

met the requirements for discharging of the Grade Three Standard as stipulated in the

Integrated Wastewater Discharge Standard (GB8978-1996).

Sludge of the sewage treatment station is the residual sludge from the biological

treatment. In order to play the biological absorption role of the residual sludge from

biological treatment and improve the dewatering performance of sludge, in the design, the

residual sludge from the biological treatment is discharged into the sludge thickening tank;

through coagulating sedimentation and sludge concentration, the supernatant liquor is

discharged back to the regulating reservoir through the clear liquid reflux pump; and the

concentrated sludge is transported to the incinerator for incinerating disposal after being

dewatered through the dewatering system.

After going through the pretreatment through the process of “pretreatment + UASB +

MBR”, the waste percolate in the proposed project can reach the influent requirement of

Daiwei sewage treatment plant of Pizhou City.

(2) Accessibility analysis on treatment effect of waste percolate

Table 8.1-1 shows the designed pretreatment efficiency of main process units after

being treated as per the sewage treatment process illustrated in Figure 8.1-1.

It can be seen that after going through the treatment measures of “pretreatment +

plant of Pizhou City.

(3) Comparative investigation on successful operation practice of similar enterprise

(1) Comparability analysis

The project of waste percolate and other sewage treatment by Taicang Xiexin Waste

Incineration Power Generation Co., Ltd. is used as a comparison project. Figure 8.1-2 shows

the waste percolate and other sewage treatment process. Compared to this project, the

difference is that the domestic sewage is treated together with such sewage with high

concentration as waste percolate, but its core treatment process is the same as that of this

project, and MBR technique is adopted for treatment in both the two projects.

(2) Result of comparison

According to the inlet monitoring data of sewage pretreatment facilities of



282

Taicang Xiexin Waste Incineration Power Generation Co., Ltd. provided by the

Environmental Monitoring Center of Jiangsu Province, it can be seen that the

pollutants can reach the level-three standard of Table 4 of Integrated

Wastewater Discharge Standard (GB8978-1996) and standard of Table 1,

which can explain that MBR technique can treat such high-concentration

sewage as waste percolate and waste platform flushing water, thus, the waste water

treatment measures used in this project are feasible.

In addition, for domestic waste percolate (including landfill) treatment, more treatment

plants adopt the sewage treatment process based on MBR, plants adopting MBR process

include: Qingdao Xiaojianxi Refuse Landfill, Beijing Gao'antun Refuse Landfill, Beijing

Beishenshu Refuse Landfill, Central Waste Incineration Plant of Zhongshan City, Shanghai

Jiangqiao Waste Incineration Plant, Changshu Waste Incineration Plant, Refuse Landfill of

Foshan City, Wuhan Chenjiacun Refuse Landfill, Shanghai Pudong Waste Incineration Plant

etc., and good effects are achieved in these plants.

Therefore, the adoption of MBR-based sewage treatment process is suitable for the

treatment of waste percolate of waste landfill and waste incineration plants, to adopt the

process of “pretreatment + UASB + MBR” in this project can make the discharge of such

high-concentration sewage as waste percolate reach the standard.

8.1.2 Sewage influent feasibility analysis of this project

(1) Treatment process and effects of Daiwei Sewage Treatment Plant of Pizhou

According to the On the Reply to the Environmental Impact Assessment Report of

Daiwei Sewage Treatment Plant Project of Pizhou (XHXS [2012] No. 22), the scope of

service of Daiwei, Pizhou includes the industrial wastewater produced in the west and north



284

area of Guanhu River of Pizhou Economic Development Zone, domestic sewage of township

of Daiwei Town, part of the wastewater of chemical enterprises in the east of Guanhu River,

Pizhou Economic Development Zone, and sewage produced by the Jinfenghuang

Furnitureland and textile enterprises in the east of Jianshe North Road. The sewage treatment

plant is under construction currently and is expected to be completed by the end of 2012. Via

the process of “Coagulating sedimentation + hydrolysis and acidification + A/O + secondary

sedimentation + anti-nitrification + disinfection”, the tail water is guided to the tail water

guidance project of Xuzhou City through a dedicated pipeline.

Figure 8.1-3 shows the sewage treatment process flow diagram.

Figure 8.1-3 Sewage Treatment Process Flow Diagram of Daiwei Sewage Treatment

Plant of Pizhou



285

Inflow water of Daiwei Sewage Treatment Plant of Pizhou performs the Level-three

standard as stipulated in the Integrated Wastewater Discharge Standard (GB8978-1996), and

the quality of effluent shall execute the primary standard (Class A) as stipulated in the

Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant

(GB18918-2002).

(2) Influent feasibility analysis on the project sewage

The planned sewage treatment capacity of Daiwei Sewage Treatment Plant of Pizhou is

20,000 m3/d, the sewage treatment plant is under construction currently and is expected to be

completed and put into operation by the end of 2012. The total length of the supporting pipe

network of Daiwei Sewage Treatment Plant is 89.4 km, in which the first-phase pipe network

is 13.78 km long, which are respectively the sewage pipelines of the five roads, i.e. Huashan

North Road, Taishan Road, Pingguo West Road, Liaohe West Road and Qiantang River Road.

Its service covers such settled enterprises as in the National Bio Energy, Yizhou Coking Ltd,

its service area is approximately eight square kilometers. The main network pipeline, 8.68

km long, has been fully completed. Currently, the sewage pipe network has been paved in the

south road section (Pingguo West Road) of the place the project is located, upon the

completion of this project, it will be directly accessed to this pipe network.

Sewage discharge quantity of this project is about 149m 3/d, accounting for 0.75% of

the treatment capacity of the sewage treatment plant. Meanwhile, waste percolate of the

proposed project can reach the influent standard of Daiwei Sewage Treatment Plant of

Pizhou through pretreatment, therefore, the wastewater produced in the proposed project can

be drained into Daiwei Sewage Treatment Plant of Pizhou. Daiwei Sewage Treatment Plant

of Pizhou has agreed to accept the wastewater of this project (see Annex 11).

Therefore, from the analysis on the water quantity, quality and scope of service, the

access of wastewater produced in this project into Daiwei Sewage Treatment Plant is

feasible.

8.2 Waste Gas Treatment Measures

8.2.1 Incinerator waste gas treatment measures

8.2.1.1 Treatment process

Waste incineration means that combustible components of waste produce chemical

reaction with oxygen in the air in 800～1000℃ incinerator, releasing heat and transforming

into high temperature combustion gas and solid residue. Apart from harmless CO2 and water

vapor, the combustion gas contains many pollutants which shall be disposed properly to

avoid secondary pollution. Although tail gas treatment equipment used for the incineration

system is the same as ordinary air pollution prevention facility, tail gas and pollutants

produced from waste incineration have special properties, so special treatment system shall

be adopted to realize up-to-standard emission.

(1) Control generation and emission of dioxins

Urban domestic waste contains many chlorine-containing high polymer materials such

as plastic, rubber and synthetic fiber, which provides precondition for generation of dioxin.

Therefore, inappropriate process and technique and improper operation during the domestic

waste incineration treatment process might cause pollution of air, water resource and soil. In

this project, pollution control equipment adopts "SNCR (inside incinerator) + half-dry + dry

+ activated carbon injection + bag" to reduce dioxin amount by reducing generation of

dioxin in incinerator and preventing re-synthesis of dioxin outside of the incinerator under

low temperature. Incineration combustion chamber shall have sufficient combustion

temperature and gas residence time to ensure proper oxygen content in the waste gas, so that

dioxins in the waste can be decomposed and damaged; secondly, re-synthesis of dioxins out

of the incinerator shall be avoided.

Dioxins are compounds with high boiling point and low vapor pressure. When flue gas

temperature is low, they are more likely to be translated into fine particles; therefore,

bag-type dust remover can more effectively remove dioxins under low gas phase temperature.

Table 8.2-1 lists data of dioxins measured in commercial incineration plant (full continuous

combustion system) of the Mitsubishi Heavy Industries/Martin Consortium.

When combustion condition of incinerator remains unchanged, and after the flue gas

temperature decreasing from 200℃ to 150℃, concentration of dioxins at the outlet of the

bag-type dust remover will be further lowered; under the operating temperature of 200℃,

outlet concentration is between 0.23 TEQng/m3 and 0.29 TEQng/m

3, while under the

operating temperature of 150℃, outlet concentration is 0.01 TEQng/m3, much lower than

that under the operating temperature of 200℃.

Table 8.2-2 lists the data of dioxins generated from dry flue gas treatment system under

the temperature of 200℃ in urban waste incineration plant (full continuous combustion

system).

Table 8.2-2 suggests that the concentration of dioxins at inlet is between 0.92

TEQng/m3

and 1.55 TEQng/m3, and that at emission outlet is between 0.03 TEQng/m

3 and

0.04 TEQng/m3. Dioxin emission standard for this project is 0.1TEQng/m

3, so emission

concentration of dioxins is far lower than national emission standard.

In this project, the following measures are taken to curb generation of dioxin:

Optimize waste storage pit design and intensify operation management to increase

heat value of waste entering into incinerator and ensure normal and stable combustion of

waste in the incinerator, and the specific measures are:



288

――Increase capacity of the waste storage pit, and the effective capacity shall be

designed as that the pit can store waste of more than 7 days to ensure that water in the waste

can be fully leached;

――Sound percolate drainage and collection system enables smooth drainage of

percolate in the waste pit;

――Through scientific management on feeding waste, for instance, transfer stack and

handle waste in the storage pit, so that heat value of waste feeding into incinerator can be

elevated.

By adopting the above measures, heat value of waste entering into incinerator can be

effectively elevated even when waste water content is high in summer, thus ensuring full and

stable combustion of waste in incinerator.

During grate design, lengthen grate dry section, strictly control mechanical load of

the grate, select incinerator that best suits low heat value waste combustion, and optimize

grate design to enhance thermal radiation inside incinerator, thus guaranteeing dry and

complete combustion of waste in the incinerator and ensuring that furnace temperature is

above 850℃.

Steam air pre-heater in this project can elevate combustion air temperature;

heat-insulating materials are applied on the lower half of furnace and the first channel,

together with unique front and back arch and secondary air which disturb combustion,

burning flue gas and combustion air can mix completely to ensure that glue gas residence

time exceeding two seconds when the temperature is higher than 850℃, thus facilitating

decomposition of dioxin in large amount.

Each incinerator is equipped with one set of diesel fuel auxiliary combustion

system composing oil storage tank, filter, oil pump, nozzle, automatic ignition, flame

monitoring, fire alarm and restarting equipment. As the incinerator can operate continuously

for over 8000 hours per year, the auxiliary fuel system is basically out of operation under

normal condition. But under a few circumstances, excessive low waste heat value will lead



289

to automatic operation of the auxiliary burner if the temperature inside the furnace is lower

than 850℃.

Based on practices of foreign incineration plants, concentrations of CO and

elemental carbon have certain relevance to concentration of dioxin, concentrations of CO

and elemental carbon in flue gas represent one of important index measuring whether waste

is completely burned, the lower the concentrations of CO and elemental carbon are, the more

complete the combustion is. For this project, concentration of dioxin is reduced by adjusting

air flow, speed and injection position to reduce concentrations of CO and elemental carbon.

By control combustion well, temperature of flue gas in the furnace or that of flue

gas before entering into waste heat boiler will be no lower than 850℃, residence time of flue

gas in the furnace and secondary combustion chamber is no less than two seconds and O2

concentration is no less than 6%. Rationally control air rate, temperature and injection

position of combustion air, or the "Three-T" control method. Practices of foreign waste

incineration plants suggest that the majority of primary dioxin in waste can be decomposed

under the above conditions.

During flue gas treatment and emission process, time duration when flue gas

temperature is between 300℃ and 500℃ shall be shortened as much as possible, and

exhaust gas temperature of waste heat boiler shall be controlled within 200℃. Bag filter is

adopted to remove dust in flue gas and reduce re-synthesis of dioxin.

A complete set of advanced, perfect and reliable automatic control system is

adopted in this project to facilitate sound operation of incineration and flue gas purification

system. Flue gas treatment system combining "SNCR (furnace) + half-dry + dry + activated

carbon injection + bag + " is adopted. As a high boiling point substance, dioxin is fine

particle in flue gas (at temperature of 150～180℃) near the bag-type dust remover; when it

passes through the remover, it will be filtered and gradually accumulated on powder layer, so

that dioxin can be removed from the flue gas. In this project, waste gas is cooled in the

half-dry neutralizing tower and the inlet temperature of the remover is controlled at 160℃,



290

so that harmful organic pollutant can be condensed on fly ash and removed by the remover

while collecting dust. Meanwhile, activated carbon injection device is set along the flue

entering into the remover, the activated carbon (with size below 100 m) will be sent into

reaction tower through compressed air to further absorb dioxin. Relevant data suggests that

activated carbon can effectively remove dioxins in the flue gas after incineration, with

removal efficiency reaching over 98%.

(2) Control of heavy metals in waste gas

Heavy metals in this project are absorbed by activated carbon. Taking Hg as an

example, the majority of Hg in the flue gas exists in gaseous status, mainly oxidized HgCl2

and part of gaseous element Hg. Blow the activated carbon into the upstream of the flue gas

pipeline of the bag filter and remove heavy metals through absorption reaction, and the

removal efficiency can reach 90% at least.

(3) Flue gas purification system

"SNCR (furnace) + half-dry + dry + activated carbon injection + bag " flue purification

system is adopted in this project. Flue gas emitted from boiler tail will enter into flue gas

purification device, see Figure 8.2-1. Slaked lime slurry will be injected into dry absorption

tower from bottom up or from up bottom using high efficient atomizer. Tail gas and injected

slurry shall fully contact concurrently or reversely and have neutralization reaction; acidic

gases are removed in the half-dry neutralization tower, and its main role is deacidification

and neutralization, thus removing such acidic gases as hydrogen chloride, hydrogen fluoride,

sulfur dioxide and sulphur trioxide in the flue gas; to protect the subsequent bag-type dust

remover, one flue gas cooling tower is set to reduce the temperature of flue gas to 160℃ by

spraying water. Inject slaked lime powder and activated carbon between the cooling tower

and the bag-type dust remover to remove acidic gases, heavy metal and dioxin in the flue gas,

the main system equipment include lime powder storage device, activated carbon storage and

conveying device. Directly inject slaked lime powder and activated carbon powder into

pipelines through high efficient nozzle. Slaked lime transported from outside the plant will



291

be transported to storage bin through tank car, and dust remover is set at the bin top to collect

dust; flue gas after reaction and absorption will enter into the bag-type dust remover,

particulate pollutants in the waste gas will absorb on filter layer when they passing through

filter bag, and then remove them by means of vibration, reverse flushing or pulsating

flushing. The dust removal effect is related to waste gas rate, temperature, dust content and

filter bag material, particles with size between 0.05 and 20 m can be removed. The bag-type

dust remover will trap and emit fine dust grains, neutralizer and acid reaction product

particles, activated carbon particles adsorbing dioxins and heavy metals.

Figure 8.2-1 Flue Gas Purification Process Chart

(4) Denitrification system

In-furnace denitrification system is adopted in this project.

Selective non-catalytic reduction process (SNCR) is adopted in the in-furnace

denitrification system. A set of SNCR (selective non-catalytic reduction method) denitration device is

equipped to remove nitrogen oxides, reduce NOx to N2 through chemical reaction by injecting ammonia



292

solution in the first passage of boiler, which can drop the content of NOx in fuel gas to lower than

200mg/Nm3. By adopting selective non-catalytic reduction (SNCR) process in the incinerator for

denitrification, the purification efficiency can reach 30%-50%.

8.2.1.2 Actual operation condition of similar project

In this project, "SNCR (furnace) + half-dry + dry + activated carbon injection + bag "

flue gas purification system is adopted. Same as this project, the flue gas purification process

of Everbright Environmental Energy (Suzhou) Co., Ltd. adopts the process of "SNCR

(furnace) half-dry + dry + activated carbon injection + bag-type dust removal" to treat waste

gas, and see Table 8.2-1 for waste incinerator flue gas measurement results. Based on actual

operation condition of Everbright Environmental Energy (Suzhou) Co., Ltd., pollutants are

controlled as per relevant requirements. In summary, the project adopts the "SNCR (furnace)

+ half-dry + dry + activated carbon injection + bag" flue gas purification system and all

pollutants can meet the stringent control requirement of EU 2000 standard.

8.2.2 Odor control measure review

(1) Waste incineration plant odor prevention & control measures

Malodorous gas of waste incineration plant is mainly from waste itself, basically near

waste storage pit, waste unloading hall, percolate storage pit and incinerator. To prevent

malodorous gas from spilling over, the following control measures shall be taken targeting

at main odor pollution sources such as the waste storage pit and waste unloading hall:

Air figure

Draw air in the waste storage pit, percolate storage pit and waste unloading hall with

primary fan, and use it as incinerator combustion air. Air drawn firstly goes through dust

removal by filtration and then enters into furnace through preheater, and malodorous gas

will be removed through decomposition and oxidation during the combustion process.

Block curtain

Inlet and outlet of waste unloading hall shall be set with air curtain to prevent

malodorous gas and dust from releasing to the outside.

Isolate the waste unloading hall and waste storage pit

Several unloading doors which can be quickly opened and closed shall be set between

the waste unloading hall and waste storage pit to enclose malodorous gas and dust into the

waste storage pit area; the waste unloading doors shall be airtight during peacetime to

enclose malodorous gas into the storage pit. The place above the waste storage pit shall

have a negative pressure.

Strengthen operation management on the waste storage pit

Operation management on the waste storage pit shall be regulated, constantly mix

and stir waste with grab bucket to make heat value of waste entering into the furnace

uniform and avoid anaerobic fermentation of waste and generation of malodorous gas.

Closed residue treatment system

Carry out closed negative pressure operation on residue storage pit using the closed

residue conveying system, and malodorous gas will be sent to the waste storage pit through

fan as primary combustion air.

During the operation stage, malodorous gas management shall be intensified, for



295

instance, reduce stop production frequency across the plant as much as possible, keep

normal operation of primary air figure system, waste carts entering the plant shall be closed

ones, close the waste storage tank unloading door if not used to close the waste pit.

(2) Stench prevention and control measures during waste transportation

Measures preventing waste percolate from leaking from waste truck include:

The newly purchased waste truck must be totally-enclosed automatic unloading

ones so as to prevent stench from spreading, dripping and leaking.

After finishing collecting operation in the project area, firstly drain the percolate

in sewage collection box into centralized sewage treatment facility through sewage pipeline

network of waste transfer station, and the percolate shall be transported after water drain

valve of drip-proof device is closed. Conduct daily supervision and examination on

percolate anti-dripping facilities of waste trucks, replace rubber seal strip at a regular basis

and replace damaged parts.

Environment and health department shall intensify daily road supervision and

examination, such phenomena as flying waste, scattering and dripping percolate are strictly

prohibited during transportation. Arrange more cleaning personnel and increase cleaning

shift of road where waste transportation passes, increase frequency of cleaning, flushing

and water sprinkling.

3 Prevention and control of stench in percolate treatment station

Waste percolate collection system is composed of percolate tank, percolate pump

room and trench, setting with mechanical air supply and exhaust system. Exhausted air will

be sent to waste bin through two deodorization fans.

Capped sealing of the waste percolate treatment structure. Stench shall be

exhausted to the negative pressure zone of the dump pit.

8.2.3 Summary

Based on a comprehensive analysis of the waste gas treatment measure taken in this

project, and by comparing with the actual treatment effect of incineration plant under

operation, dioxin emission can be controlled at 0.1ng (TEQ)/m3

after the project is put into

operation, and up-to-standard emission of heavy metals, fly ash, acidic gases and other



296

pollutants can also be achieved; stench control measures taken can ease its impact on the

surrounding environment, and waste gas from the fly ash solidification workshop can be

emitted according to standard after going through the bag-type filter. Therefore, by taking

comprehensive and effective treatment technology and measures, waste gas treatment

technology adopted in this project can protect the surrounding environment and air quality

to the maximum extent.

8.3 Noise Control Measures and Overview

The noise sources of this project are mainly aerodynamic equipment (for instance,

fan), high power pump, etc. Based on the equipment situation, the following noise

reduction measures will be taken:

(1) Control value and safety valve on the air exhaust pipelines of boiler shall be of

low noise type, air exhaust muffler shall be installed and damping treatment shall be made

for pipelines between the valve and muffler.

(2) The fan shall be set in sound proof box and exhaust muffler shall be installed.

(3) Vibration dampers such as rubber joint shall be installed on pumps; anti-vibration

pads shall be set on water pump and other foundations.

(4) Building materials with good sound insulation and sound attenuation performance

shall be adopted in boiler room.

(5) Tighten maintenance of management and mechanical equipment.

(6) Main plant shall be arranged in a rational way to ensure concentrated distribution

of noise source; soundproof architectural structure shall be adopted in control room and

operation room. In control room where operating and management personnel are

concentrated shall be set with acoustic device (for instance, sealed door and window) at

doors and windows, and acoustic suspended ceiling shall be adopted to reduce the impact

of noise on operating personnel and make the working environment meeting the allowable

noise standard.

(7) Rationally arrange general layout and strengthen plant area greening to reduce

the impact of noise on the surrounding environment.



297

Meanwhile, in response to traffic noise generated by transportation vehicle in the

plant area, such measures as overload restriction, regular vehicle maintenance and no

horning in the plant area will be taken to reduce traffic noise.

By adopting the above treatment measures, plant boundary noise satisfies Class III

standard as stipulated in Emission Standard for Industrial Enterprises Noise at Boundary

(GB12348-2008); therefore, noise in this project will have small impact on sensitive points.

8.4 Solid Waste Pollution Control Measures and Overview

During the production process, many solid wastes will be generated. The main solid

wastes include slag, fly ash, sewage treatment sludge and domestic waste.

(1) Slag

Slag-drip opening of the incinerator is at the bottom of grate, slag will be sent to slag

pit through remover. Slag conveyor is equipped with automatic humidifying device to

prevent slag from flying.

Slag can be used as fuel for brick making, aggregate of silicate products, road or roof

insulation material, or as cement raw materials. Slag produed in this project is sent to

Pizhou Xutang New Building Materials Co., Ltd. for comprehensive utilization, to be used

as brick making materials or roadbed, building materials.

(2) Fly ash

According to Technical Policy for Prevention and Control of Hazardous Waste Pollution (H. F.

[2001] No. 199), fly ash generated during domestic waste incineration process must be collected

separately, and it shall not be mixed with domestic waste, slag, other wastes and hazard wastes; it shall

not be stored in generation place for a long time, nor shall it be disposed simply or emitted.

Fly ash disposal method

In this project, chelant and cement stablization technology is adopted to treat fly ash,

of which, cement as solidifying material will be mixed with chelant to stablize hazardous

matter in fly ash. The purpose of chelant stablization is to facilitate heavy metals in fly ash

in generating stable compounds like sulfide, hydroxide, chelate and other complex

compounds under the action of drugs, so as to reduce emission of heavy metal in fly ash



298

into the environment and stablize fly ash. DTC chelants developed by Tsinghua University

upon years of research are adopted in this project. DTC chelants are odorless and

non-corrosive transparent liquids. During cement stablization process, dicalcium silicate

and tricalcium silicate in cement will be turned into CaO·SiO2·mH2O gel and Ca

(OH)2·CaO·SiO2·mH2O gel through hydration reaction, which will cover fly ash before

gradually hardening and forming CaO·SiO2 stabilized body of high mechanical strength.

The presence of Ca (OH)2 lead to higher PH value, so that most heavy metal irons generate

insoluble hydroxide or carbonate and be fixed on cement matrix lattice, thus effectively

preventing heavy metal from leaching. Relevant test data suggests that fly ash solidification

effect is the best when cement ratio is 0.33. The stablized products shall undergo landfill

treatment after hydration process is completed after a certain time of curing and standard

requirements are satisfied.

Fly ash property analysis

According to leaching toxicity test on solidified fly ash sample of Yixing Domestic Waste

Incineration Plant, concentrations of pollutants in solidified leaching liquid of incinerated fly ash sample

are: Yixing Solid Waste Incineration incineration fly ash sample leaching results of toxicity tests, the

burning of the pollutant concentration in the fly ash sample leaching solution: Hg <0.02mg/L, Zn

0.031mg/L, Ba 0.422mg/L, As 0.569mg/L, total Cr 0.314mg/L, hexavalent chromium 0.314mg/L, Pb

0.479 mg/L, Ni 0.012 mg/L; copper, cadmium, beryllium, selenium are not detected, all these figures

meet requirements of Table 1 of Pollution Control Standards in the Domestic Waste Landfill

(GB16889-2008).

Both the major construting company of this project and Yixing are the subsidiary companies of

Everbright Group; they have similar methods of fly ash disposal and management. Upon the completion

of the project, after fly ash is solidified, concentrations of all pollutants in leaching liquid can meet the

control requirements; then the fly ash is intended to be sent to Suqian Xiaoling waste landfill for

landfilling.

According to leaching toxicity test on solidified fly ash sample of Qidong Domestic

Waste Incineration Plant, water content of solidified incineration fly ash sample is between

2.92% and 2.96%, content of dioxin is between 1.160 g TEQ/Kg and 1.4λ2 g TEQ/Kg.



299

Properties of fly ash of this project are close to those of Qidong Domestic Waste

Incineration Plant, the water and dioxin content of solidified incineration fly ash can meet

the control requirements.

Feasibility analysis on fly ash solidified body landfill

According to Pollution Control Standards in the Domestic Waste Landfill (GB16889-2008), fly

ash produced from domestic waste incineration can be landfilled in the domestic waste landfill only if

they meet the following conditions after being treated: (1) Water content shall be less than 30%; (2)

content of dioxin shall be lower than 3 gTEQ/Kg; (3) concentrations of hazardous ingredients in the

leaching solution prepared according to HJ/T300 are lower than the prescribed limits.

In accordance with the analysis on the properties of fly ash, water content, dioxin content and

hazardous components of leaching liquid after fly ash solidification can satisfy control requirements.

According to the Technical Guide of Domestic Waste Disposal: fly ash which can meet the Pollution

Control Standards in the Domestic Waste Landfill GB16889 after being treated can be landfilled in the

domestic waste landfill.

Upon the completion of this project, the major unit conducting the identification after fly ash

solidification is Everbright Environmental Energy (Pizhou) Co., Ltd. (i.e. the construction unit). Fly ash

shall be sent to Suqian Xiaoling Refuse Landfill for landfilling after fly ash solidification. Domestic

Waste Landfill of Xiaoling Village is located in Xiaoling Village, Caoji County Suyu District Suqian

City, its environment impact assessment was replied by Suqian Municipal Environmental Protection

Agency in 2008. Xiaoling Waste Landfill has a capacity of 1.15 million cubic meters, in which 0.45

million cubic meters has been used, 0.7 million cubic meters are not used. Annex 8 shows the agreement.

Upon the completion of Pizhou Municipal Domestic Waste Landfill, domestic waste shall be sent there

for landfilling. Pizhou Municipal Domestic Waste Landfill has a proposed scale of 200 000 t/a, covers an

area of 75Mu, and is planned to be built in Lushan Village Zhancheng Town Pizhou City; it is planned to

be completed and put into operation in November 2013. Pizhou Urban Management Bureau is

responsible for the construction and operation of this project.

(3) Others

Other solid wastes include used oil, sewage treatment sludge and domestic waste.

Used oil belongs to a kind of hazardous solid waste, and it will be disposed by Suqian



300

Kelin Solid Waste Disposal Co., Ltd. (see Annex 10 for agreement and qualifications).

Sewage treatment sludge and domestic waste shall be disposed at incinerator in this

project.

The constructor shall set special stacking site. The constructor shall store and manage

as per Standard for Pollution Control on Hazardous Waste Storage (GB18597-2001) and

to prevent spreading, losing and leaking; special personnel shall be assigned to operate,

separately collect, store and transport wastes, pollution prevention and accident emergency

measures for hazardous waste transfer and transportation shall be formulated, and relevant

procedures shall be handled with in strict accordance with the requirements.

If the above solid wastes are disposed as per the measures mentioned, they will not

impact the surrounding environment and human body, nor will they cause secondary

pollution, therefore, treatment measure taken is feasible and effective.

8.5 Groundwater Pollution Control Measures and Overview

(1) Control groundwater pollution from the source

In order to protect the groundwater environment, measures are taken to control the pollution of

groundwater from the source.

Cleaner production and circular economy are implemented (see Chapter 9 for details), to reduce

314

Therefore, the project construction conforms to national and local industrial policies.

9.2 Cleaning Production Analysis

9.2.1 Advancement of furnace selected

Advanced mechanical grate furnace is adopted in this project. At present, main mature

domestic waste incinerator applied the most include mechanical grate furnace, fluidized bed

incinerator, pyrolysis incinerator and rotary kiln incinerator.

(1) Mechanical grate furnace

Mechanical grate furnace adopts stratified combustion technology, and it has such

advantages as low requirement on waste pre-treatment, wide applicable range of waste heat

value, simple to operate and maintain. It represents the most commonly used urban domestic

waste incinerator with the largest handling capacity, and has been widely used in Europe,

America and Japan, the maximum handling capacity per set is 1200t/d, so the technology is

mature and reliable. Wastes will go through two combustion sections on the grate, wastes

burn on the grate, heat energy comes from radiation and flue gas above as well as the

internal of waste layer. Waste burned on the grate lead to violent stirring and agitation of the

waste layer through special action of the grate, causing combustion at waste bottom.

Continuous stirring and agitation loose the waste layer, improve permeability and facilitate

waste combustion and burning out.

(2) Fluidized bed incinerator

The fluidized bed technology was developed some 70 years ago, it was used for

industrial sludge incineration in 1960's and for domestic waste incineration in 1970's, and it

was popularized in Japan in 1980's, with market share of over 10%. However, in the late

1990's, application of fluidized bed incinerator in domestic waste incineration reduces by

large margin due to elevated flue gas emission standard, high fly ash volume and hot burning

lapse rate of the fluidized bed and difficult to control.

Incineration mechanism of fluidized bed incinerator is similar to that of coal fired

fluidized bed, waste combustion and buring out are guaranteed by large heat capacity of bed



315

material. Generally the bed material shall be heated to 600℃ before putting waste into the

incinerator, and the bed layer temperature is kept at 850℃. The fluidized bed incinerator can

treat all types of waste, and it can realize complete combustion of waste, but its demand on

crushing pre-treatment is strict, so it is prone to have fault. In China, the fluidized bed

incinerator is applied in recent years, but for some types of the fluidized bed incinerators,

coal needs to be added to realize normal incineration, so there is still dispute on its

application in waste incineration, which needs further improvement.

(3) Pyrolysis incinerator

Pyrolysis incinerator means to decompose organic matter in the absence of oxygen or

non-oxidation atmosphere under a certain temperature (500℃～600℃), then the organic

matter will have thermal cracking process and turn into pyrolysis gas (combustible gas

mixture), the pyrolysis gas then will be introduced into combustion chamber to burn and

decompose organic pollutants, waste heat is used for power generation and heat supply.

Pyrolytic technique is widely applied to treat various wastes. However, due to waste

characteristics and unstable subsequent pyrolysis gas features (heat value, composition, etc.),

combustion is hard to be controlled, slag is hard to burn out, and environmental protection

goal is difficult to be realized. This technology is applied in some small cities in Canada and

USA, but advanced regions do not apply it.

Beyond that, pyrolysis incinerator is mostly applied in rotary kiln incinerator and

fluidized bed incinerator in Europe and Japan, added with the adoption of smelting furnace,

ash slag will be completely burned out and melted into vitreous slag. This technology is

partly applied in advanced economies, but it has disadvantages like high waste heat value,

high cost of plant construction and high operating cost (which is twice of that of the

mechanical grate).

(4) Rotary kiln incinerator

Combustion mechanism of the rotary kiln incinerator is similar to rotary kiln applied in

cement industry. It is mainly composed of an inclined steel cylinder, the inner wall of the



316

cylinder is built with fire resistance material, or pipe type water cooled wall is adopted to

protect the cylinder. Waste enters into the cylinder through inlet, and rolls over and moves

forward as the cylinder rotates, and drying, burning, combustion and buring out process of

waste will be completed in the cylinder. Residence time of waste in the kiln can be adjusted

by changing cylinder rotation speed. Currently, the rotary kiln incinerator is often used for

incineration of toxic and hazardous industrial waste and medical waste with complicated

composition, and there are a few cases of its application in waste incineration.

Table 9.2-1 lists analysis and comparison result of mechanical grate furnace and

fluidized bed incinerator, two types of large-size incinerators which are universally applied

in China now.

Analysis suggests that mechanical grate furnace has the following features:

The technology is mature, almost all large-sized incinerators adopt the mechanical

grate furnace, and success precedents can be found in China.

It can adapt to characteristics of waste which has high water content and low heat

value, and ensure complete combustion of waste.

Operation is reliable and convenient, well adapted to waste, and it is not easy to

cause secondary pollution.

Highly economic, waste can directly put into incinerator without pre-treatment, so

operating cost is relatively low.

The equipment has long service life, and it is stable and reliable, convenient to

operate and maintain, and part of supporting technology and equipment are available in

China.

In Technical Policy for Disposal of Municipal Solid Waste and Pollution Control issued



318

by the Ministry of Construction, the Ministry of Science and Technology and the State

Environmental Protection Administration, it stipulates that "waste incineration shall adopt

grate furnace with mature technology, and be prudent in utilization of other types of

incinerators."

Based on the above reasons, the project adopts mechanical grate furnace which is

techncially mature.

9.2.2 Advancement of flue gas incineration treatment process

The flue gas purification process is determined according to composition and

concentration of pollutants in waste gas generated during waste incineration, as well as

emission standard to be adopted. Generally, such substances as acidic gases (HC1, SO2),

particles, heavy metals and organic poison (dioxin and furan) shall be controlled, of which,

aicd gases removal and particulate trap are key of process design. At present, main flue gas

purification processes include dry purification, half-dry purification, wet purification, NOx

purification, activated carbon injection. Each process can be combined in many ways, and all

purification processes are briefed as below.

(1) Dry purification process

The typical process combination is dry absorption reaction tower + bag-type dust

remover. Flue gas generated during incineration will directly enter into dry absorption

reaction tower where it has chemical neutralization reaction with the injected Ca(OH)2

particle in the reaction tower, generating harmless neutral salt particles, and then enter into

downstream bag-type dust remover, in which the reaction product, dust and absorbent not

involved in the reaction will be trapped, thus realizing the goal of purification.

The dry purification process is simple, with low investment, small equipment corrosion,

high flue gas temperature and without generating waste water and white smoke. Its

advantage is large agent dosage.

(2) Half-dry purification process

Half-dry purification process represents a waste incineration flue gas treatment process

which is commonly applied in Chinese and foreign waste incineration plants. The process



319

adopts Ca(OH) 2 solution as absorbent, and its typical process combination is half-dry

neutralization reaction tower and bag-type dust remover. Ca(OH) 2 solution atomizes as it

rotates in the reaction tower, forming very fine alkaline particle, and aicd gaseses turn into

salt through reaction and drop to the bottom of the tower. Aicd gaseses carring a large

amount of particles go out from the reaction tower and enter into the downstream bag-type

dust remover, some lime not reacted attach to the filter bag and react again with aicd gases

passing through the filter bag, thus further removing removal efficiency.

Half-dry purification process has similar aicd gases removing effect as that of the dry

purification process, and its advantages include low drug dosage and no waste water

generating, but its atomizing disc is prone to wear, and white smoke will be generated when

the flue gas temperature is lowered.

(3) Wet purification process

Wet purification process is widely applied in economically and technically developed

countries, and its typical process combination is wet scrubber tower and bag-type dust

remover. The wet scrubber tower is optimal for SO2 and HC1 control. Since absorption

efficiency is determined by the speed of aicd gaseses spreading to alkaline absorption liquid

drop, the process design shall be focused on gas-liquid contact area and time, as well as

increase of absorbent concentration in elevating liquid drop. The alkaline solution adopted in

the wet scrubber tower is generally NaOH solution or Ca(OH) 2 solution. Slaked lime is

cheap, so it is normally used to prepare alkaline solution. The slaked lime solution and aicd

gaseses react to form calcium salt, and cycle washing water shall be settled, concentrated and

filtered to prevent it from settling in the equipment.

The biggest advantage of the wet purification process is that it can realize high acid

removal rate, and it can also effectively remove various organic pollutants and heavy metals.

However, it is difficult to treat waste water containing high concentration inorganic chlorine

salt and heavy metals, with high equipment investment and operating cost.

(4) Activated carbon injection adsorption



320

To ensure up-to-standard emission of heavy metals (especially Hg) and organic poisons

(dioxin and furan), some foreign companies have adopted activated carbon injection

adsorption as a supporting flue gas purification measure.

Activated carbon has large specific surface area, so it has strong absorption capacity to

heavy metals and dioxin. The activated carbon injection is generally used in combination

with the bag-type dust remover. The activated carbon nozzle is set at the inlet end of the

remover (in front as much as possible), so that the activated carbon can mix with flue gas

and absorb a certain amount of pollutants, even saturated absorption is not realized, it can

absorb on filter bag and re-contact with flue gas passed to increase absorption purification

effect of pollutants and realize minimum emission.

(5) NOx purification process

The above processes can effectively purify acid gases and particles, and can also

remove heavy metals, dioxin and furan effectively, but their NOx removal effect is not

apparent. In this project, Selective Non-Catalytic Reduction (SNCR) process is adopted for

in-furnace denitrification, the principle is to reduce by injecting reducing agents in the

second burning area of the waste incinerator, and its purification efficiency can reach 30％

to 50％.

9.2.3 Automation control system

11. Environmental Economic Cost-Benefit Analysis

The development and construction of the proposed project will boost local social and

economic development, but the project construction will exert a certain adverse impact on

the construction site and the surrounding environment. During the development and

construction process, necessary environmental protection measures taken can partly

mitigate the adverse impact on environment and economic loss. In this chapter, we will

make brief analysis on environmental economic cost-benefit of the project based on the

analysis of social, economic and environmental benefits as well as environmental loss

analysis.

11.1 Analysis on Economic Benefits of the Project Investment

The project will be built by means of loan and self-raising, the total investment is 330

million Yuan. See Table 11.1-1 for main economic indicators.

Table 11.1-1 Main Economic Indicators

Items Unit Value

Unit cost of power sold

Investment payoff period (after-tax) Year 12.94

Note: Unit cost of power sole, sales revenue and sales profit are tax exclusive price; investment payoff

period includes two years of construction period.



332

Table 11.1-1 suggests that the internal rate of return, investment payoff period and

other indexes of the project are good, with small overall risk.

11.2 Environmental Investment

Based on project analysis and environmental impact forecast results, waste water,

waste gas and noise generated after the project is put into operation will have certain

impact on the surrounding environment, so the corresponding environmental protection

measures shall be taken to mitigate the impact, and environmental input shall be guaranteed

to minimize the impact of various pollutants on the surrounding environment. Table 8.7-3

lists environmental investment of the proposed project based on preliminary estimate. The

total investment is 330 million Yuan, including 66.46 million Yuan which accounts for

20.1% of the total investment.

11.3 Environmental Economic Cost-Benefit Analysis

By taking complete and reliable waste gas, waste water, noise and solid waste

treatment measures in the project, pollutants emitted into the environment can be reduced

to the maximum extent, bringing about obvious environmental benefits. In particular, it is

planned to use "SNCR (furnace) + half-dry + dry + activated carbon injection + bag "

process for flue gas purification to ensure up-to-standard emission of incinerated fuel gas;

waste percolate and flushing waste water generated in this project will be treated in the

in-plant sewage treatment station, and discharged into Daiwai Sewage Treatment Plant for

advanced treatment after it meets the influent standard; After taking a serious of

noise-reduction measures, plant boundary noise will meet standard; solid waste generated

shall be properly disposed or utilized in a comprehensive way. The impact of "three wastes"

generated in the project on the environment can be lowered significantly, thus meeting

environmental requirement. In addition, heat energy generated during waste incineration

can be used to generate power, thus achieving better environmental and economic benefits.

their response. No one objected the project. According to their questions, we concluded:

(1) Reasons for building the waste treatment plant

It is predicted that daily waste which is necessary to be removed of Pizhou in 2012 is

approximately 674 tons/day, therefore, no matter from environmental protection or health

appearance change in urban and rural areas, it is necessary to effectively dispose these garbage.

There is only one simple waste treatment plant in Pizhou, and what’s worse, it is saturated.

Currently, whether in the domestic or at abroad, the method of waste disposal is

incineration, and waste incineration technology has been matured; In view of this, Pizhou

Municipal Government decided to build a waste incineration power plant, to carry out harmless,

recycling and minimization disposal on the waste of Pizhou.

(2) Does the project affect the peripheral environment (Malodorous gas prevention and

treatment)

Malodorous gas of waste incineration plant is mainly from waste itself, basically near

waste storage pit, waste unloading hall, percolate storage pit and incinerator. To prevent

malodorous gas from spilling over, the following control measures shall be taken targeting at

main odor pollution sources such as the waste storage pit and waste unloading hall: (1) Adopt

enclosed self-discharging garbage transportation vehicle, and set waste unloading door at the

inlet and outlet of the main plant unloading platform of waste incineration plant. (2) Waste pit

is adopted with closed structure, the primary air used for combustion supporting in the

incinerator shall be drawn from the top of waste storage pit; in normal operation, waste pit

shall be kept slight negative pressure state to prevent the escape of malodorous gas. (3)

Operation management on the waste storage pit shall be regulated, constantly mix and stir

waste with grab bucket to avoid anaerobic fermentation of waste and generation of malodorous



376

gas. (4) Carry out closed negative pressure operation on residue storage pit using the closed

residue conveying system, and malodorous gas will be sent to the waste storage pit through fan

as primary combustion air. (5) During the operation stage, malodorous gas management shall

be intensified, for instance, reduce stop production frequency across the plant as much as

possible, keep normal operation of primary air figure system, waste carts entering the plant

shall be closed ones, close the waste storage tank unloading door if not used to close the waste

pit. (6) When the operation is stopped or the system is examined due to a boiler accident, the

waste storage pit shall be kept closed, and air exhaust of waste storage pit shall be deodorant

treatment with the ventilation frequency of approximately 1 to 1.5 times/hour; activated carbon

exhaust gas purification device shall be applied for deodorization, and deodorization device

shall be installed on the roof of the building next to the waste pit.

(3) Percolate and wastewater treatment

The project adopts clean water-sewage and rainwater-sewage separation for the in-plant

drainage system. Water drained from the boiler shall be used as ash cooling water, and not

discharged outside. Waste percolate shall be pre-treated through the self-built percolate

treatment facility with the main treatment process of “pretreatment + UASB + MBR

biochemical treatment” to ensure that sewage meet municipal wastewater nanotube standard

(BOD5 ≤ 300 mg/l, COD ≤ 500 mg/l, SS ≤ 400 mg/l, ammonia nitrogen ≤ 35 mg/l, pH = 6-9)

after being pre-treated; and then it shall be sent to Daiwei Sewage Treatment Plant for

integrated treatment through the municipal sewage pipe network. Other cleaning wastewater

and domestic wastewater shall be directly discharged into the municipal sewage network.

(4) Up-to standard emission

Pollutants produced from waste combustion mainly include dioxins, acid gases (SO2, HCl,

NOx), smoke dust and heavy metals. Fuel gas treatment system of the waste incineration

project for power generation in Pizhou adopted the combined disposal system of “half-dry +

dry reaction Tower + SNCR” and “de-nitrification + activated carbon + bag filter”. 1. Source

control of dioxin: 3T technology is adopted in this project to reduce and control the generation

of dioxin from the source. Through “three T” control method, the temperature can be



377

controlled more than 850 ℃, residence time of fuel gas in furnace is more than 2S, flue gas

with high temperature may fully disturb to produce turbulent flow so that no temperature

corners of flue gas are ensured, thus the majority of primary dioxin in waste can be

decomposed. 2. Fuel gas adopts the “half-dry + dry reaction tower” process for de-acidification

disposal to remove such acid gases in fuel gas as SO2 and HCL; SNCR de-nitrification device

is to inject a certain amount of ammonia water in the furnace chamber to do de-nitrification

treatment on NOx in fuel gas; the purpose of activated carbon injection is to adsorb heavy

metals in dust and further adsorb the dioxin; bag filter is mainly used to filter the smoke; after

being treated through the above environmental protection methods, emission indexes of fuel

gas can meet the stringent control requirement of EU 2000 standard.

(4) Supervision of waste incinerator

The entire process of design, construction and operation management of the waste

incineration project for power generation shall be supervised; supervision is divided into

government and public supervision. 1. Functional departments of government shall strictly

supervise the project’s review, design and construction process, to ensure up-to-standard

emission of wastewater and fuel gas; the project shall be in real-time networking with the

environmental protection department, and shall be under the government’s 24-h supervision;

emission data shall be publicized in real time on the on the electronic display screen at the

plant door. 2. The project shall be under the supervision of public at all times and places; any

violations or accident polluteing the environment shall be reported immediately. 3. Everbright

International shall take the initiative to accept social supervision, listen to the views of the

public, continuously improve the management, and implement in real earnest the responsibility

of environmental protection.

13.6 The public participated in the research conclusion

(1) According to provisions of Interim Procedures for Public Participation in

Environmental Impact Assessment, the hearing accords to the principle of publicity and fairness.

The public can participate in the survey through the ways of checking the notice on the Internet,

issuing the questionnaires, media report and holding a hearing.



378

(2) The issuing range of questionnaires should be within 3000 meters of the project. The

emphasis is the surrounding residents. The effective questionnaires are 167. Through the

analysis, the age, education and the occupational structure distribution should be

representative.

Among these 167 people, 50.3% support the project, and 49.7% will also support if their

requirements can be satisfied. They hope that we can strengthen the power of the supervision

and protection on environment, enhance the treatment technologies, improve the process

equipments, reinforce the check on exhaust air and make the information public. No one

objects the project.

(3) As for the requirements that the residents put forward and their worry about the

environment, in the process of construction, we must emphasize on the environmental

protection and take measures to control the waste water, exhaust gas, noise, and solid waste.

The pollutants can not be emitted until they meet the standards of steadiness and functional

zone. Strengthen the management on environment and ensure the full feasibility of the project.

At the same time, the enterprise should strengthen the advertisement of the project and make

the data of surrounding environment public. So the public can have a clear and right

understanding about the prevention measures and the impacts on environment.

(4) Attitude of the contractor: let the residents participate in the research through many

ways and we can see that the contractor pays more attention to the suggestions of the public.

The contractor adopts some feasible suggestions. In the process of construction, we must

strength environmental awareness and put every measure of protecting environment into

practice. Strengthen the management on environment and try to reduce the impacts on

surrounding environment. So the related competent departments should strengthen the

supervision to ensure the running of the project according to the design principle and the

implementation of all measures of protecting environment.

The public participate in the research, and they are satisfied with the general

environmental quality of the region. Most residents will support the project if the contractor

can meet their requirements. At the same time, all measures of pollution prevention must be

taken. Strengthen the management on environment, and the pollutants should be emitted when



379

they reach the steady standard. Avoid disturbing the normal life of residents.

13.7 Grievance Redress Mechanism

Pizhou Project has established an online monitoring system to make sure all

environmental data comply with the national and regional laws and regulations. Monitor many

relevant parameters such as concentration of flue dust (particulates), SO2, NOx and CO, flue

gas flow rate, temperature, humidity and oxygen content, etc, and record the discharge rate and

total discharge amount ,etc. Pizhou Environment & Municipal Administration Bureau and

Urban Management Bureau are in charge of supervision. If there is excessive discharge or

pollution accident, Pizhou Environmental Protection Bureau and Construction Bureau will

conduct investigation. Local citizen will directly make complaint to local government.

Hold meeting with environmental protection bureau and surrounding villages and citizens.

Set up complaint call: 0516-86221213

Public survey during the environmental impact assessment has been carried out. There are

many ways for public participation. Public participation in the environmental assessment

adopts online notice, newspaper notice and public participation questionnaire and public

hearings, and the investigation is combined by representativeness and randomness. Set up

complaint call: 0516-86298208

At construction phase of project, strengthen the environmental protection awareness,

eliminate the illegal acts, implement different environmental protection management measures,

strengthen environmental management and reduce the impact to the surrounding environment

as much as we can. The environmental protection administrative department will strengthen the

supervision, guarantee the project operation according to the design principles and implement

different environmental protection measures. Set up complaint call: 0516-86298958

When any dispute arises from project construction and operation, public may file an

appeal with competent authorities. Assigned person will responsible for record and documents

file. Authority, Project Company, local citizen and the complainants will implement on-site

inspect. Related to the complaint from Environmental Protection Bureau, Project Company

will cooperate with local authorities on supervision and inspection. The results and amend

must report to the relevant departments and publics.

14 Feasibility Analysis of Site Selection

According to H. F. (2008) No. 82 Document, as for the waste incineration and electric

power project, there are some formulations on conformance of plan, susceptibility of site

environment, equipment selection, emission standard of pollutants and so on. This chapter will

analyze the feasibility of the project according to the provision of the document.

14.1 Site Selection of Incinerator

14.4.1 Basis principles and requirements of site selection

(1) According to the related contents of Standard for Pollution Control on the Municipal

Solid Waste Incinerator (GB18485-2001), “when we choose the site, we must accord with the

overall plan of urban and rural development, environmental protection program and the special

plan of environmental sanitation. Accord with the requirements of air pollution control, water

resources protection, natural conservation and related standard of nation”.

(2) According to the provisions of “The construction standard of urban waste

incineration and processing project”, site selection should accord with the following

requirements: Accord with the overall plan of urban and rural development, the special

plan of environmental sanitation and related standards of nation. The impacts on the

surrounding environment of waste incineration power plant should accord with the related

requirements of environmental protection. The waste incineration power plant should

accord with air pollution control, water resources protection, natural conservation. The

transportation is convenient and the distance is reasonable. The cost of land acquisition is

less and the construction is easy. Density of population is small and the value of land use is

less. It is located at the downwind direction of prevailing wind in summer. In addition, consider

the change of the quantity of rubbish and the site should have extent scope to develop.

(3) According to “Notice of strengthening the management on the environmental

assessment of bioelectrogenesis project” (H. F. 2008 No. 82), “the land use should accord

with urban development plan, environmental protection program and land policy of nation.

Besides the areas being forbidden to as the site of pollutional project by national and local



381

provisions, standards and policies. The following areas generally are forbidden to build waste

incineration power projects.

Built-up areas in big and medium cities and city planning area

Upwind direction of leading wind in town or big concentrated residential area;

The areas in which the environmental protection objects in sensitive area can not reach

the corresponding standards and requirements.

14.1.2 Comparison and selection of the sites

According to the actual situation, the contractor, Pizhou Urban Management Bureau and

other related departments made on-the-spot surveies on the site suitable for building waste

incineration power generation project, and determined three sites suitable for the construction.

The locations are seen in picture 14.1-1.

1) Site 1: Qufang Village, Daiwei Town

The site is located in Qufang Village of Daiwei Town (south of Baiguo West Road, east of

Hongqi Road, west of Taishan Road, and facing Pingguo Road in the south); it has an available

land area of about 100 mu; the nature of land is construction land; and the park already has

sewage pipe network. The site is located at the downwind direction of prevailing wind of the

main urban area; there are no residents living within the surrounding range of 300m; it is 6km

from the water source, 7km from Zhaodun Power Substation, thus the investment amount in

power access system is large. If a plant is built here, transportation of materials will become

convenient during the construction period, and waste transport channel will be smooth after the

plant is put into operation.

2) Site 2: Paoche Industrial Park, Paoche Town

Site 2 is located in Paoche Industrial Park of Paoche Town; it has an available land area of

about 80 mu; and the nature of land is for construction. The site is located at the upwind

direction of prevailing wind of the main urban area; there are small amount of residents living

within the surrounding range of 300m; it is 6km from the water source, 3km from Hongwei

Power Substation, thus the investment amount in power access system is small. If a plant is

built here, transportation of materials will become convenient during the construction period,



382

and waste transport channel will be smooth after the plant is put into operation.

3) Land for Third-Phase Construction of Fushan Medical Products Co., Ltd in Yitang

Town

Site 3 is the land for third-phase construction of Fushan Medical Products Co., Ltd. in

Yitang Town; it has an available land area of about 80 mu; and the nature of land is for

construction. The site is located at the downwind direction of prevailing wind of the main

urban area; there are small amount of residents living within the surrounding range of 300m; it

is 6km from the water source, 4km from Yitang Power Substation, but the site passes through

the residential area, circuit is complex, thus the investment amount in power access system is

moderate. If a plant is built here, transportation of materials will become convenient during the

construction period, and waste transport channel will be smooth after the plant is put into

operation.

Through a comprehensive analysis on the three proposed sites, it can be seen that the

nature of land of site 1 is for construction, there are no residents within the surrouding range of

300m, Site 1 is located at the downwind direction of the urban area, water taking and sewage

drainage are convenient, power supply is far but the access is convenient; there are residents

living within the surrounding range of 300m of Site 2 and Site 2 is located at the upwind

direction of the urban area, which is not in line with the requirements for plant construction;

although Site 2 is located at the upwind direction of the urban area, there are residents living

within the surrounding range of 300m, which is also not compliant with the requirements for

plant construction. Upon a comprehensive comparison, it is suggested Site 1, i.e. Qufang

Village of Daiwei Town (south of Baiguo West Road, east of Hongqi Road, west of Taishan

Road, and facing Pingguo Road in the south), be the proposed site of the project.

14.2 Analysis of Conformity with Relevant Planning and Provisions

(1) Conformity with Urban Master Planning of Pizhou (2011-2030)



384

According to the description on “environmental protection project in municipality” (see

section 2.5.1.1 for details) in Urban Master Planning of Pizhou (2011-2030), this project (i.e.

domestic garbage incineration project for power generation in Pizhou) has not been included in

the planned construction project, but the planning mentioned that “give priority centralized

incineration for the domestic waste, utilize energy in a cyclic manner, adopt new land-save,

sustainable waste landfilling method for slag disposal, recycle the biogas produced from

landfilling”. In addition, according to the the survey, proposed City River Waste Disposal Sites

in Zhaodun Town has not yet been built. According to “Description on the Distribution of

Pizhou Domestic Waste Incineration Power Generation Project” issued by Pizhou People’s

Government (Attachment 2) and Urban Master Planning of Pizhou (2011-2030) which will be

edited and revised by domestic waste incineration power generation plant in Pizhou, site

selection of the project is compatible with Urban Master Planning of Pizhou. Therefore,

construction of this project does not conflict with Urban Master Planning of Pizhou

(2011-2030).

Picture 14.2-1 shows Urban Master Planning of Pizhou.

(2) Conformity with Special Plan for Environmental Health of Pizhou (2012-2030)

On June 5, 2012, Pizhou Urban Management Bureau organized the demonstration on

Special Plan for Environmental Health of Pizhou (2012-2030); and agreed the planning

contents proposed in the Planning in principle. See Attachment 5 for details of review opinions,

which mentioned that “domestic waste incineration disposal contents are appropriately added

in the planning according to the reality and urban development needs; reutilization,

minimization and hazard-free treatment of waste resources are achieved; and sufficient

augumentation and comparison of programs are made on waste production, waste disposal

methods, the size and location of treatment plant, thus, the planning is feasible.” In addition,

the planning contents of domestic waste incineration power generation plant in Pizhou

described in “Description on the Distribution of Pizhou Domestic Waste Incineration Power

Generation Project” issued by Pizhou People’s Government will be included in Special Plan



385

for Environmental Health of Pizhou. Therefore, site selection of the project is compatible with

Special Plan for Environmental Health of Pizhou.

Therefore this project meets relevant requirements of Special Plan for Environmental

Health of Pizhou (2012-2030).

(3) Conformity with landing planning

It can be seen from Picture 14.2-1 that site of the project is located in the planned industrial

land. According to “Description on the Distribution of Pizhou Domestic Waste Incineration

Power Generation Project” (Attachment 3) issued by Pizhou People’s Government, the project

is compatible with the requirements of overall planning of land utilization, and production and

living requirements met for the surrounding roads, water supply, communications, and other

supporting facilities. A preliminary site selection opinion was issued by Pizhou Planning

Bureau and Pizhou Land and Resources Bureau. See Attachment 3 for the details of “Opinion

on Site Planning of Pizhou Domestic Waste Incineration Power Plant” issued by Pizhou

Planning Bureau; see Attachment 4 for “Primary Opinion on Land Use in the First Phase

Domestic Waste Incineration Power Generation Project of Pizhou” (P.G.T.Z.[2012] No.1)

issued by Pizhou Land and Resources Bureau.

(4) Analysis of conformity with Ecological Function Reserves Planning of Jiangsu

Province

Based on Ecological Function Reserves Planning of Jiangsu Province., the proposed

location of this project does not belong to Jiangsu important ecological functions protected

areas.

Therefore, this project is compatible with Ecological Function Reserves Planning of

Jiangsu Province.

(5) Analysis of conformity with South-to-North Water Diversion Waste Treatment

Project Planning

Pollutant interception and river diversion project of Eastern South-to-North Water

Diversion Route in Xuzhou is totally 170.28 km long; its main task is to use the existing canals

and newly opened channels to transport the tail water treated through the upstream sewage

treatment plant into the downstream tailrace, eventually discharge it into Beipianhong mouth of



386

Xinxi River, to separate the tail water system in Xuzhou and water delivery trunk line of

eastern south-to-north water diversion route, so as to water quality of the eastern south-to-north

water diversion route in Xuzhou reach standard of surface water.According to the

South-to-North Water Diversion Waste Treatment Project Planning, the section of canal in

Pizhou belongs to a water quality sensitive area in major control areas. Clear water of this

project shall be discharged into the main canal on the south side of the plant area. Wastewater

shall be discharged into Daiwei Sewage Treatment of Pizhou after being pre-treated until it

reaches the standard for draining; tial water of sewage treatment plant shall be drained into the

sea through the stream guidance project, and shall not be emitted into the surrounding water

body.

This project is compatible with South-to-North Water Diversion Waste Treatment Project

Planning.

(6) Analysis of conformity with Regulations of Jiangsu Province on Prevention and

Control of Solid Waste Pollution

Regulations of Jiangsu Province on Prevention and Control of Solid Waste Pollution puts

forward special provisions to the pollution prevention of urban and rural household garbage,

requiring as followsμ “the governments of municipality and county with sub-districts should

plan as a whole, build transport system for urban and rural household garbage and harmless

disposal facility, gradually achieve urban and rural communal building and sharing; for the

construction of disposal system of household garbage, the governments should adopt advanced

technology and equipment, and advocate to adopt advanced technologies such as incineration

power generation, etc.

Nanjing is a county-level municipality with sub-districts. This project is household

garbage incineration power generating project which will become Pizhou household garbage

disposal facility once built, therefore it is in conformity with the requirements of Prevention

Regulations for Jiangsu Solid Wastes Pollution Environment.



387

14.3 Analysis of Conformity with H. F. 2008 No.82 Document

H. F. 2008 No.82 Document puts forward relevant requirements to household garbage

incineration power generation in plant location, equipment selection, pollutants control,

garbage collection and transport, environmental risk, environmental protection distance, public

participation, etc. This report puts forward requirement of measures in relevant section around

these aspects; now, we will list the conformity between this project and H. F. 2008 No.82

document for comparison, see Table 14.3-1.

According to the comparison in Table 14.3-1, The project planning satisfy relevant

planning requirments and waste heat value and amount meet project demand. The project site

is not selected in city and town or large and concentrated residential area which are in upwind

direction under prevailing wind direction, added with advanced and reliable process and

equipment as well as feasible pollution control measures, pollutants can be emitted under

certain standard. The environmental quality of the project site is good, and the project

construction will not decrease the environmental functions. Feasible odor control measure can

minimize its impact on the surrounding environment; the 300-meter environmental protection

distance is set outside of the plant boundary, there are no sensitive targets within the distance

range. The environmental risk is generally acceptable. In summary, the project meet H. F.

[2008] No. 82 Document requirements.



388

Table 14.3-1 Analysis of Conformity between This Project and H. F. 2008 No.82 Document

SN Document Requirements Implementation

1. Plant location

Garbage incineration power generation applies to the

developed areas, where average lower calorific value of

feeding garbage is higher than 5000 kilojoule/kg, and

where lack of sanitary landfill.

Current household garbage disposal of Pizhou mainly relies on a

simple landfill. With the increase of garbage day by day, current

sanitary landfill cannot meet the requirement of garbage disposal.

According to the research of the project, standard lower calorific

value of household garbage of Pizhou is set as 4614 kJ/kg

(1104kcal/k). The heat value of waste in the furnace will increase

after discharging 15-25% of percolate when storing in the waste

warehouse for 5 to 7 days, meeting the requirement in Article 21 of

Standard for Building MSW Incineration Project that the heat value

of waste shall be higher than 5000kJ/kg. Therefore, the fuel of this

project can be guaranteed in quantity of supply and calorific value.

Plant location must be in line with master planning,

land utilization planning and sanitation professional

planning (or centralized disposal planning of urban

household garbage, etc) of its city, and should meet the

requirements of Planning Specification for Urban

Sanitation Facility (GB50337-2003), Code for

Municipal Solid Waste Incineration Processing Project

(CJJ90-2002),.

In addition to the areas that national and local laws and

regulations, standards, policies prohibit the location for

pollution projects, the projects of household garbage

On relevant planning: According to the documents issued by

Pizhou People’s Government, this project meets the requirements of relevant planning such as Urban Master Planning of Pizhou, Special

Plan for Environmental Health of Pizhou (2012-2030), etc.

Upon the completion of the project, it has a positive significance in promoting

the development of circular urban economy, effectively controlling pollution

and improving people’s living environment.

On land utilization: The plant is located at Qufang Village,

Daiwei Town, Pizhou, where does not belong to urban built-up areas,

and the land has obtained preliminary permission of Pizhou Planning

Bureau, Land Department (see Attachment).

Prevailing wind direction of the plant location is east wind; plant



389

incineration power generation must not be newly built

in following areas: (1) Urban built-up area; (2) The

areas where environmental quality cannot meet the

standard and have no effective reduce measures; (3)

The areas which may cause that environmental

protection target of sensitive area cannot reach to

corresponding standard.

location of this project meets the requirement that it is not in the

upwind of prevailing wind direction of towns or large residential

areas.

Water quality of the water bodies such as Guhu River, and City River which

are monitored this time are poor with some indicators exceeding the

requirements of evaluation criteria, for this, Pizhou Municipal People's

Government issues the “Integrated Improvement Program on Water

Environment of Pizhou”; relevant management department will strengthen

local environmental management, and take comprehensive environmental

remediation measures, thus, there will be a significant improvement in water

environment in the area of Pizhou. In general, environmental quality of

plant location is preferable; during operation, it will not cause

environmental function of sensitive target in surrounding

environment decreases through prediction if preventions of various

pollution are put in place.

Therefore, this project meets the requirement that it should not be

built in urban built-up area, areas where environmental quality

cannot reach to the standard and have no reduce measures, and areas

which can cause environmental protection target of sensitive area

cannot meet corresponding requirements.

Standard (0.1TEQng/m3 at present) is implemented; this project

adopts Selective Non-Catalytic Reduction (SNCR) denitration in

incinerator, and the removal rate to nitrogen oxides is 40%; this

project is equipped with fumes automatic continuous monitoring

device.

The report clearly states in the chapter of monitoring plan that

burning temperature, CO, oxygen content in incinerator should be

monitored, and networking with environmental protection

department should be made to meter the application rates of active

carbon.

Disposal measures of acidic and alkaline waste water,

cooling water sewerage and other industrial sewage

should be rational and feasible; for the disposal of

garbage percolate, recycling spraying should be taken

into account; if the percolate cannot be recycled, it

should assure that the dewatering reaches to state and

local relevant emission standard; garbage percolate

collecting pond with enough volume should be set up;

generated sludge or concentrated solution should be

voluntarily incinerated in plant and not be transported to

other place for disposal.

Treatment Plant of Pizhou until it reaches the influent standard

through being disposed by self-built water treatment system.

If the garbage percolate is directly recycled and back sprayed into

the incinerator, which causes the temperature of furnace cavity

decreases, not only cannot the garbage be fully burned, but also may

large amount of dioxin be generated. Otherwise auxiliary fuel must

be added, which may increase the loss of conventional energy

resources, and also increase operating expenses. Therefore, direct

recycling spraying is not considered for percolate at present. A set of

500m3 garbage percolate collecting pond is set up.

Generated sludge and concentrated solution are fully sent back to

the incinerator for incineration, and it is not allowed to be transported

to outside.

Incineration slag and incineration fly ash collected by

dust-cleaning apparatus should be collected, stored,

transported and disposed respectively. Because

incineration slag is ordinary industrial solid wastes, the

project should set up corresponding magnetic separator

to separate and recycle the metals, and then conduct

comprehensive utilization, or dispose of and store

according to the requirements of Standard for Pollution

Control on the Storage and Disposal Site for General

Industrial Solid Wastes (GB18599—2001); fly ash

resulting from incineration is hazardous wastes, which

should be stored, disposed according to Standard for

Incineration slag generated from the project and fly ash collected by

dust-cleaning apparatus are collected, stored, transported and

disposed respectively. Parts of the slag are comprehensively utilized;

the project sets up corresponding magnetic separator to separate and

recycle metals and then comprehensively utilizes them; all indicators

of fly ash meet the requirements of Table 1 of Standard for Pollution

Control on the Landfill Site of Municipal Solid Waste

(GB16889-2008) after being solidified and stabilized in the plant; the

fly ash will be sent to Jiangning Shuige Landfill for disposal through

partition after its stable solidification meets above standards. Once

Jiangnan Ecological Landfill is built, the fly ash will be sent to this

landfill after being solidified.



393

Pollution Control on Hazardous Waste Storage

(GBl8597-2001) and Pollution Control Standards for

Hazardous Wastes Landfill (GB18598-2001);

positively encourage comprehensive utilization of fly

ash from incineration, but adopted technology should

assure complete break of dioxin and effective fixation

of heavy metals, and secondary pollution will not be

caused during production and application. After

Standard for Pollution Control on the Landfill Site of

Municipal Solid Waste (GB16889-2007) is put into

effect, the disposal for incineration slag and fly ash can

be implemented according to the new standard.

Measures to prevent and control the stink: Garbage

discharging, garbage transport system and garbage

storage pool and others should adopt sealed design, of

which, garbage storage pool and garbage transport

system adopt operation mode of negative pressure;

structures of disposing garbage percolate should be

sealed with a cover. Under abnormal conditions,

effective measures of removing the stink must be taken.

Garbage discharging, garbage transport system and garbage

storage pool and others adopt sealed design, of which, garbage

storage pool and garbage transport system adopt operation mode of

negative pressure; structures of disposing garbage percolate should

be sealed with a cover.

When overhaul the incinerator, this project is designed to adopt

active carbon deodorization device to remove the stink, and the

efficiency of active carbon for removing stink can be up to over

80%; treated NH3, H2S can meet the requirements of Emission

Standards for Odor Pollutants (GB14554-93).

4. Garbage

Collection,

It is advocated that the garbage should be collected at

Transport and

Storage

the calorific value of garbage, percolate generated from

garbage transfer station is not suitable for entering

garbage incineration plant.

combustible garbage, recoverable matter, hazardous garbage and

large garbage at the source; in the view of transport routes of

garbage, the mode of collection by areas and sections is adopted; for

transport mode, the combination of large transfer station and small

transfer station is adopted; garbage percolate from transfer station is

discharged through urban sewage pipe network, and it will not enter

garbage incineration plant, which effectively assure calorific value of

incoming garbage.

Transport route for garbage should be rational; the

transport vehicle must be airtight and equipped with

measures for preventing the leakage of garbage

percolate; back loading compression type garbage

transport vehicle which meets key indicators and

technical requirements of Catalogue on the

Environmental Protection Equipment (Products)

Currently Encouraged by the State to Develop (the First

Batch) (Revised in 2007) should be adopted.

Currently, most garbage transport vehicles of Pizhou are back

loading compression type which are airtight and prevent leakage, so

the leakage of percolate along the way can be prevented. Once this

project is built, the range of garbage collection is larger than the

previous one, and the transport routes are rational on the whole. After

relevant measures are taken, it will not cause that environment

function of sensitive target along the way of garbage transport

decreases.

The bottom and four sides of walls of garbage storage

pool and percolate collecting pond should take the

measures to prevent the leakage of garbage percolate;

In this project, garbage storage pool, percolate collecting pond and

their four sides of walls are equipped with impervious barrier.

Take effective measures to prevent odor pollutants from

escaping.

Hazardous wastes are not allowed to enter household

garbage incineration power plant for disposal.

On the prevention of stink: This project takes measures such as air

draft, separated curtain to main odor gas pollution source such as

garbage storage pool, garbage discharging lobby, and takes measures

such as isolation, standardizing operation and management of

garbage storage pool and slag disposal closed system to unloading



395

lobby and garbage storage pool (please see the section of preventions

for details) to minimize the effect of stink.

On the entering of hazardous wastes: Strengthen management,

and prevent hazardous pollutants from entering garbage incineration

plant from the source.

5.

Environmental

Risk

Environmental Impact Report must set special chapter

for environmental risk impact assessment to emphasize

the effect of dioxin and odor pollutants.

Accident and risk evaluation criterion should be

implemented by referring to acceptable daily intake of

human body 4pgTEQ/kg. Allowable intake of human

body through inhalation should be implemented

according to 10% acceptable daily intake of human

body.

This report should present possible effected range

according to calculated results, and draw up prevention

of environmental risk and emergency plan to

completely eradicate environmental contamination

accident.

According to relevant prediction of Section 5.2, the effect of

pollutants such as dioxin on neighboring environment of proposed

project under abnormal condition and accident discharge is higher

than that under normal condition, but it can still meet the standard of

relevant assessment which is lower than acceptable daily intake of

human body 4pgTEQ/kg, i.e.10% acceptable daily intake of human

body. Under accident condition, total emissions of odor gas is little

and correspondingly its effect on neighboring environment is also

little after being collected through exhaust funnel, absorbed by active

carbon. In order to prevent accident and reduce harm, contractor will

draw up emergency plan. When accident takes place, emergency

measures are taken to effectively control the accident and reduce the

harm to environment. On the whole, the level of risk can be accepted.

Environmental

Protection

Distance

According to the calculation result of fugitive emission

source intensity which generates odor pollutants

(ammonia, hydrogen sulfide, methyl mercaptan, odor,

etc) under normal working condition and appropriately

consider the conclusions of environment risk

assessment, the project should put forward rational

According to Section 5.2 and its relevant prediction, and combine the

requirements of H. F. 2008 Document, the project is set with a

300-meter environmental protection distance. There are no sensitive

targets within this protection distance (See the attachment for the

temporary makeshift shelters which will be demolished).



396

environment protection distance as the control space

between it and surrounding residents and schools,

hospitals and other public facilities, and as the basis of

plan control. The environment protection distance of

newly reorganized and expanded project should be not

less than 300m.

7. Total

Pollutants

Control

The project must put forward regional balance plan to

newly increased pollutants emissions and define the

source of total emissions to realize “Increase Output and Decrease Pollutants”.

Total pollutants of the project can be balanced in Pizhou.

8. Public

Participation

The work of public participation should be carried out

strictly according to Interim Procedures for Public

Participation in Environmental Impact Assessment (H.

F. [2006] No. 28). The object of public participation

should cover affected publics representatives, experts,

technicians, representatives of grassroots government

organization and relevant benefited publics. We should

increase the transparency of public participation;

appropriately organize symposiums, exchange meetings

to make the publics communicate with relevant

personnel. We should conclude and analyze public

opinions, communicate with the publics who disagree,

and feed back to contractor to put forward

improvements, finally put forward advice to whether to

take public opinions. For the projects with environment

Public participation of this project adopts media publicity,

questionnaire, filed visits, media report, public hearing and other

forms, and the object of public participation covers affected publics

representatives, experts, technicians, representatives of grassroots

government organization and relevant benefited publics. We

conclude and analyze public opinions, communicate with the publics

who disagree; contractor takes parts of advice and explains the

reason why some opinions are not taken. Therefore, public

participation of this project meets the requirements of Interim

Procedures for Public Participation in Environmental Impact

Assessment (H. F. [2006] No. 28).



397

sensitivity, large dispute, local governments at all levels

should conduct interpretation work to the publics; when

necessary, convene public hearing.

9. Monitoring

and Impact

Prediction for

Current Status

of

Environmental

Quality

Besides relevant requirements of guide rule of

environmental impact assessment, we should do well

following work: (1) Current status monitoring:

rationally determine monitoring factors according to

emission standard. It is necessary to set two monitoring

points, with one at the closest sensitive point of

downwind of prevailing wind direction and the other

nearby the maximum ground level concentration point

of pollutants, so as to monitor dioxin in atmosphere;

separately set a monitoring point for dioxin in soil at

upwind and downwind of prevailing wind direction; for

downwind, it is suggested to choose the planting soil

nearby the ground with maximum concentration of

pollutants.

According to relevant requirements, the unit of environmental impact

assessment issues monitoring plan for dioxin, and Taizhou

Environmental Monitoring Central Station carries out monitoring for

current status of dioxin in atmosphere and soil. The result of

monitoring indicates that the dioxin of environmental background

can meet relevant standard of environmental quality.

(2) Impact prediction: before the state has not

formulated the standard for environmental quality of

dioxin, the assessment should be implemented by

referring to Japan annual average concentration

0.6pgTEQ/m3 . Enhance environmental impact

prediction of odor pollutants, adopt long-term

meteorological condition, calculate successively day by

day, and present the maximum qualified distance

The standard for environmental quality of this project is implemented

by referring to the standard of Japan annual average concentration

0.6pgTEQ/m3 . The project predicates environmental impact of

odor pollutants. Environmental impact assessment of atmosphere

adopts long-term meteorological condition to successively calculate

day by day, and the maximum qualified distance is calculated

according to the standard of environmental impact assessment.



398

according to relevant environmental assessment

standard; the environmental impact of qualified plant

can be determined according to odor concentration

research and monitoring analogy of garbage power

plant with similar technology and scale.

(3) Daily monitoring: after garbage incineration power

plant is put into operation, at least annual monitoring of

dioxin in atmosphere and soil should be conducted to

fumes emission and above monitoring points of current

status so as to timely understand and master the

condition of garbage incineration power generating

project and the dioxin of its surrounding environment.

In environmental monitoring plan this report requires that regular

monitoring of fumes and dioxin should be carried out after the

project is built. Contractor undertakes to at least conduct annual

monitoring of dioxin in atmosphere and soil to fumes emission and

monitoring points of current status according to the requirements of

H. F. 2008 No. 82 Document after garbage incineration power pant

is put into operation.

10. Water

The water of garbage power generating project should

accord with state water policy. Advocate to process

reclaimed water of the plant with urban sewage. For the

northern areas lacked of water, surface water is

prohibited to use, and underground water is strictly

prohibited to use.

This project adopts surface water, rather than underground water.

Fresh water consumption is lower than the index of similar projects.

Each portion of waste water in plant is discharged into municipal

sewage pipe network after being collected and treated and reaching

to the standard of discharging. The plant saves water resource and

reduces the emission of water pollutants after taking these measures

for saving water.

15. Conclusions

15.1 Project Overview

Currently, there is one garbage dump in Pizhou, which is located at the junction between

Pisui Road in the southwest of the urban area and Huancheng West Road; it adopts the disposal

process of simple stacking, and has no hazard-free treatment capability; it was built in 1994

and has been satured currently. In recent years, with the rapid development of economy and

urban construction in Pizhou, domestic waste in Pizhou keeps growing, and domestic waste

disposal volume in Pizhou will reach 222,400 tons in 2012, then a situation in which there are

no places for disposing domestic waste in Pizhou will be faced. Relevant research results by

Pizhou municipal party committee and government departments show that conditions of

incineration for power generation is available, and waste incineraton for power generation

technology is mature, so it is planned to build domestic waste incineration power plant in

Pizhou.

In April 2012, the construction of first-phase domestic waste incineration project for

power generation in Pizhou was invested by China Everbright International Co., Ltd. in the

way of BOT. Site selection is located in Qufang, Daiwei Town of Pizhou (south of Baiguo

Road, east of Hongqi Road, west of Aishan Road, and facing Pingguo Road in the south);

planned plant area is 100 mu. The constructon scale is designed to handle 600 tons of urban

domestic waste every day, and 220,000 tons of domestic waste every year. The project mainly

composes of production and ancillary works, as well as utilities, which cover new garbage

receiving, storage and transport system, burning system, flue gas treatment system, waste heat

utilization system. Two mechanical grate furnaces with a daily handling capacity of 300t will

be adopted, two waste heat boilers with the maximum continuous evaporation capacity of

25.4t/h, and one condensing steam turbine generator unit with installed capacity of 12MW are

also used, with annual generation capacity of 68,000,000 kWh. The total investment of the

project stands at 0.33 billion Yuan, including 66,460,000 Yuan of environmental protection

investment or 20.1% of the total investment.



400

Envrionmental assessment on water supply network and other supporting facilities shall

be formulated separately.

15.2 Current Environmental Quality Basically Meets Standard

In this environmental quality status assessment, air, surface water, groundwater, sound

environment and soil samples on the site are taken and tested. The environmental quality status

monitoring has been completed by Huai’an Environmental Monitoring Central Station. the

monitoring result indicates that:

Atmospheric environment: hour (primary) concentrations of SO2, NO2, PM10, HCl, NH3,

H2S, Hg, Pb, Cd at each monitoring points in the assessed area satisfy the Class II standard as

stipulated in the Ambident Air Quality Standard (GB3095-1996) and relevant requirements of

Sanitary Standard for the Design of Industrial Enterprise (TJ36-79). Odor concentration is less

than 10, meeting class II plant boundary standard as stipulated in Emission Standards for Odor

Pollutants (GB14554-93).

In this assessment, water quality of Chenghe River and the surrounding Guanhu River

where water is taken is poor. Of the monitoring factors of Chenghe River, ammonia nitrogen,

total phosphorus, BOD5 can not meet category water standard requirement as stipulated in

Environmental Quality Standards for Surface Water (GB3838-2002), but others can meet. Of

the monitoring factors of Guanhu River, SS, COD, total phosphorus, ammonia nitrogen,

permanganate index, BOD5 can not meet category water standard requirement as stipulated

in Environmental Quality Standards for Surface Water (GB3838-2002), but others can.

In view of this, Pizhou Municipal People's Government issues the “Integrated

Improvement Program on Water Environment of Pizhou”; relevant management department

will strengthen local environmental management, and take comprehensive environmental

remediation measures, thus, there will be a significant improvement in water environment in

the area of Pizhou.

Acoustic environment: acoustic environment around the project site is better, and the

acoustic environment quality in the project area meet type II standard as stipulated in



401

Environmental Quality Standards for Noise.

Ground water: of all monitoring factors for ground water environment of the five

monitoring points, pH, permanganate index, Cr6+

, ammonia nitrogen, As, Pb, Cd, total fecal

coliform, nitrate nitrogen and nitrite nitrogen satisfy type III water quality requirements as

specified in Quality Standard for Ground Water (GB/T14848-1993), ground water environment

quality is good.

Soil: all monitoring factors (PH, nickel, chromium, lead, cadmium, mercury, arsenic,

copper and zinc) at the project site and surrounding area meet class II standard requirement as

specified in Environmental Quality Standard for Soils (GB15618 95), and soil environment at

the project site and surrounding area is good.

Beyond that, the constructor has entrusted Taizhou Environmental Monitoring Central

Station to carry out dioxin status monitoring and analysis. Based on the monitoring point

distribution principle as stipulated in concerning document, two dioxin sampling points are set

in the assessment range to monitor soil and dioxin contents in the atmospheric air. The

monitoring result suggests that concentrations of dioxin in the air and soil do not exceed

relevant standard requirements.

respectively, meeting the assessment standard; the maximum annual ground level

concentration occurs at place near 560m; average annual concentrations of SO2, NO2, PM10 and

dioxin at environmental sensitive protection targets meet assessment standard.

Under abnormal conditions: impact of abnormal emission of hydrogen chloride and

dioxin on external environment is greater than that under normal conditions. The maximum

contribution value of average hour concentration of hydrogen chloride under abnormal

conditions exceeds standard (around 1,,500m), the maximum impact predicted value of

hydrogen chloride at each protection targets meet the maximum allowable concentration in

residential area as specified in Sanitary Standard for the Design of Industrial Enterprise

(TJ36-79); the amout of dioxin inhaled by normal adults in protected residential area is lower

than the allowable intake of human body through respiration.

Therefore, mangements shall be tightened and effective measures shall be taken to ensure

normal ooperation of waste gas treatment facilities; in case of inition, shut down or if furnace

temperature fails to meet requrements due to other reasons, raise temperature by injecting

diesel to support combustion and reduce generation of dioxin.

(4) Environmental protection distance



404

A 300-meter environmental protection distance is set outside of the plant boundary. There

are no sensitive environmental protection targets such as residents within the protection

distance, only on the southwest side of the plant site (north side of Hongqi Community) there

are 31 temporary houses, and only one is lived by an elderly couple. The temporary housing is

temporary transitional houses for demolition of Hongqi Community. Currently resettlement

houses for demolition (Hongqi New Village) have been fully put into use, thus all temporary

houses will be demolished before the end of December 2013. Land within the environmental

protection distance shall not be used for construction of settlement, school, hospital and other

sensitive targets, and food processing, medicine and cosmetics projcts which have demanding

requirements on air environment quality shall not be constructed in the site.

(5) The 80m stack adopted in this project is feasible in terms of impact on ambient air

15.3.2 Surface water environmental impact

Waste percolate of this project will be discharged into Daiwei Sewage Treatment Plant of

Pizhou for disposal with other sewage after being pretreated through the self-built

“pretreatment + UASB + MBR biochemical treatment” disposal device. The scale of Daiwei

Sewage Treatment Plant of Pizhou after it is completed is 20,000m3/d, it is predicted to be put

into operation by the end of 2012. Sewage emission amount of this project is approximately

149m3/d, accounting for 0.745％of the disposal capacity (20,000m3/d) of the existing sewage

treatment plant; sewage of this project can be drained into Daiwei Sewage Treatment Plant of

Pizhou through pipelines.Wearing dike Pizhou City sewage treatment plant built 20,000 m3 / d,

is expected to be operational by the end of 2012. Of the project's sewage discharge is about

149m3 / d, accounting for the existing sewage treatment plant capacity (20,000 m3 / d) 0.745%,

and may take possession of the emissions to Pizhou City wearing dike sewage treatment plant.

15.3.3 Sound environment impact

After the project is completed, plant boundary sound environment can meet standard by

rationaly arrange noise euqipment and taking effective acoustic noise reduction measure. There

are no sensitive sound environmental protection targets within 200 meters away from the plant



405

boundary, so the project will not disturb residents after it is completed.

15.3.4 Impact of soild waste on environment

All solid wastes generated in the project can be effectively treated or disposed, so the

project will not cause secondary pollution.

15.3.5 Acceptable environmental risk level

Environmental risks during the production process mainly include three conditions: under

abnormal condition: firstly, supporting flue gas treatment facilities of incinerator fails to meet

waste gas emission standard under normal treatment efficiency; secondly, abnormal emission

of dioxins are cuased by incinerator start up (temperature rise), shut down (flame out) or due to

management or human factor, for instance, abnormal emission of dioxin in case of insufficient

furnace temperature; thirdly, excessive CO amount in incinerator lead to explosion accident

and impact the surrounding environment. Under abnormal condition and accident emission,

impact of dioxins and hydrogen chloride on the surrounding environment is greater than that

under normal conditions, but it can stil meet relevant assessment standard. In case of maximum

credible accident, environmental sensitive protection targets around the project site can be

affected to different degrees. It is necessary to tighten sudden accident pollution monitoring

and precaution, and emergency plan shall be formulated to handle with accidents, and social

emergency measures shall be taken if necessary to control the impact of accident on

environment. Risk level is acceptable after the enrionmental risk precaution measures are put

into place after the project is put into overall operation.

section of canal in Pizhou belongs to a water quality sensitive area in major control areas.

Rainwater of this project is discharged into a main canal on the south side of the plant area.

Wastewater is discharged into Daiwei Sewage Treatment of Pizhou; tial water of sewage

treatment plant is drained into the sea through the stream guidance project, and is not emitted

into the surrounding water body. Therefore, the project construction is compatible with the



408

South-to-North Water Diversion Waste Treatment Project Planning.

(6) Conformity with the requirements as stipulated in Regulations of Jiangsu Province on

Prevention and Control of Solid Waste Pollution

Nanjing is a county-level municipality with sub-districts. This project is household

garbage incineration power generating project which will become Pizhou household garbage

disposal facility once built, therefore it is in conformity with the requirements of Prevention

Regulations for Jiangsu Solid Wastes Pollution Environment.

(6) The project planning satisfies relevant planning requiments and waste heat value and

amount meet project demand. The project site is not selected in city and town or large and

concentrated residential area which is in upwind direction under prevailing wind direction,

added with advanced and reliable process and equipment as well as feasible pollutin control

measures, pollutants can be emitted under centain standard. The environmental quality of the

project site is good, and the project construction will not decrease the environmental functions.

Feasible odor control measure can minimize its impact on the surrounding environment; the

300-meter environmental protection distance is set outside of the plant boundary, there are no

sensitive environmental protectioin targets within the distance range. In summary, the project

meet H. F. [2008] No. 82 Document requirements.

15.4.3 Advanced cleaning production level

The project adopts advanced and rational production process, heat energy generated

during waste incineration is used for power generation to supplement insufficient power supply

capacity, and thus it has significant energy-saving effect. The adoption of advanced process

equipment and production control technology enables that pollutants generation and emission

amount as well as pollution control measure reach advanced domestic level, some indexes even

reach advanced international level.

15.4.4 Feasible pollution prevention and control measures

15.4.4.1 Feasible waste water pollution prevention and control measure

Water drainage system for this project is adopted with water-sewage separation system.



409

Drained circulating cooling water (193t/d) is reused for slag cooling, fly ash solidification, flue

gas purification and garbage truck washing, unloading platform rinsing and ground road

rinsing. Waste percolate 120m3/d and cleaning wastewater 12m

3/d are pre-treated through

self-built percolate treatment facilities, domestic wastewater 17m3/d is directly discharged into

the municipal pipe network, and Daiwei Sewage Treatment Plant of Pizhou.

By comparison with other waste percolate treatment examples, it can be concluded that

percolate produced in this project can fully meet the influent standard of Daiwei Sewage

Treatment Plant of Pizhou after being pretreated through the self-built “pretreatment + UASB

+ MBR biochemical treatment” processing device. Wastewater produced in this project can

meet the requirements as stipulated by Daiwei Sewage Treatment Plant of Pizhou in terms of

water quantity and quality.

15.4.4.2 Feasible waste gas pollution control measures

(1) Incinerator waste gas control measures

Flue gas purification system

Flue gas purification in this project adopts the combined process of “half-dry + dry

reaction tower + SNCR denitration + activated carbon + bag filter”. Slaked lime slurry will be

injected into dry absorption tower from bottom up or from up bottom using high efficient

atomizer, thus effectively reducing gas temperature and neutralizing acidic gases. Inject

activated carbon to absorbe dioxins and heavy metals and then send them into the bag-type

dust remover where fine dust particles, neutralizer, deacidification reaction product particles,

activated carbon particles absorbing dioxins and heavy metals are trapped and emitted, and

dust content of flue gas at outlet of the bag-type dust remover meets emission standard.

Meanwhile, furnace denitrification system is adopted to ensure nitric oxides be emitted under

certain standard.

The main measures for dioxin and furan emission in the project include:

a. Each incinerator is set with a set of diesel fule auxiliary combustion system;

b. Mature and reliable furnace and grate structure are adopted to ensure complete



410

combustion of waste in the incinerator. In the process for this project, concentration of dioxin is

reduced by adjusting air flow, speed and injection position to decrease concentrations of CO

and elemental carbon.

c. The majority of original dioxin is decomposed by adopting the “Three T" control

method, i.e. control of temperature, time and turbulence.

d. Residence time of flue gas under the temperature of between 300℃ and 500℃ during

treatment and emission process shall be shortened as much as possible, and exhaust gas

temperature of waste heat boiler shall be controlled within 200℃. Bag filter is adopted to

remove dust in flue gas and reduce re-synthesis of dioxin.

e. Flue gas treatment system is adopted with a combined process of half-dry neutralizing

tower/bag-type dust remover, so that harmful organic pollutants can be condensed on fly ash

which will be removed by the bag-type dust remover during dust collection process. Activated

carbon injection device is set along the flue entering into the remover to further absorb dioxin.

Control of heavy metals in waste gas

a. Do well source control and collect waste separately.

b. Inject activarted carbon to absorb heavy metals. Taking Hg as an example, blow

activated carbon into upper reach of the flue gas pipeline in the bag filter and remove Hg

through absorption reaction, and the removal efficiency is around 90%. Accoridng to foreign

data, the combined process of half-dry neutralizing tower+bag filter has an optimal removal

efficiency of 99% in actual tests.

Incinerator denitrification system

In this project, furnace denitrification system is adopted. Selective Non-Catalytic

Reduction (SNCR) process is adopted for denitrification, anad its purification efficiency can

reach 30％～50％. After the above treatment, NOx concentration can be lowered to below

190mg/Nm3.

(2) Overview on stench control measure

The main odor pollution source is raw waste. Main compoents of malodorous gases



411

emitted from the waste truck during unloading process and from the wate storage pit are H2S

and NH3. The following methods are adopted to control malodorous gas emission: adopt

enclosed waste truck; the waste unloading hall and waste storage pit shall be arranged in

an enclosed way; air curtain shall be set at entrance and exit of the waste unloading hall in

main incineration plant; all doors of the waste storage pit leading to toher areas shall be of

double-layer enclosed ones; automatic unloading enclosed door is set to enclose the waste

storage pit; exhaust air above the waste storage pit and slag storage tank is used as

combustion air to form negative pressure in the storage pit and slag storage tank and prevent

odorant from overflow; regulate operation management on waste storage pit, constantly

mix and sstir waste through grab bucket to avoid anaerobic fermentation of waste and

generation of odorants; spray bactericidal agent and deodorant in the waste storage pit

regularly; during incinerator blown out for overhaul, open electrically operated valve and

deodorization fan, and then malodorous gas will be absorbed and filtered by activated carbon

deodorization device and emitted into the atmosphere after meeting standard.

Based on comprehensive analysis on waste gas treatment mesures, and by comparing with

the actual treatment result of similar incinerator in operation, dioxins emitted in the project can

fully meet the standard requirement of 1.0 ng(TEQ)/m3

as specified in Standard for Pollution

Control on the Municipal Solid Waste Incinerator (GB18485-2001) and 0.1ng(TEQ)/m3 as

specified in European and American standards, and pollutants such as heavy metals, fly ash

and acidic gases emission can be meet standard requirement; odor control measures taken can

alleviate the impact of odorant on the surrounding environment. Atmospheric environmental

impact forecast results show that plant boundary concentration of malodorous gas emitted

inorganically in the project satisfy standard emission requirements. Waste gas treatment

technology adopted by this project is guaranteed by comprehensive and effective treatment

technology and measures, thus protecting the surrounding environment and improve the air

quality.

(3) Noise control measures



412

The noise sources of this project are mainly aerodynamic equipment (for instance, fan),

high power pump, etc. Based on the equipment situation, the following noise reduction

measures will be taken: control value and safety valve on the air exhaust pipelines of

boiler shall be of low noise type, air exhaust muffler shall be installed and damping treatment

shall be made for pipelines between the valve and muffler; the fan shall be set in sound

proof box and exhaust muffler shall be installed; vibration dampers such as rubber joint

shall be installed on pumps; anti-vibration pads shall be set on water pump and other

foundations; building materials with good sound insulation and sound attenuation

performance shall be adopted in boiler room; tighten maintenance of management and

mechanical equipment; Main plant shall be arranged in a rational way to ensure

concentrated distribution of noise source; soundproof architectural structure shall be adopted in

control room and operation room. In control room where operating and management personnel

are concentrated shall be set with acoustic device (for instance, sealed door and window) at

doors and windows, and acoustic suspended ceiling shall be adopted to reduce the impact of

noise on operating personnel and make the working environment meeting the allowable noise

standard.; rationally arrange general layout and strengthen plant area greening to reduce

the impact of noise on the surrounding environment.

(4) Solid waste treatment and disposal measures

During the production process, many solid wastes will be generated. The main solid

wastes include slag, fly ash, used oil, sewage treatment sludge and domestic waste.

Based on similar domestic waste slag leaching test data, slag belongs to general solid waste

which is planned to be utilized comprehensively by sending it to Pizhou Xutang New

Building Materials Co., Ltd.; fly ash belongs to hazardous waste, and fly ash after

solidification treatment can satisfy Pollution Control Standards in the Domestic Waste Landfill

(GB16889-2008), and then sent to Suqian Xiaoling Waste Landfill for treatment; after Pizhou

Domestic Waste Landfill is completed, fly ash will be sent to Pizhou Domestic Waste Landfill

for landfill disposal; used oil belongs to a kind of hazardous solid waste, and it will be



413

disposed by Suqian Kelin Solid Waste Disposal Co., Ltd.; waste treatment sludge and

domestic waste will be sent into the incineration system of the project for disposal.

15.4.5 Total amount balance in the area

二、建设单位及环评机构所做项目环境影响报告书概要说明

⒛12年 3月 2日 ,邳州市城管局与中国光大国际有限公司

(下简称“光大国际

”)通过特许经营权协议谈判,确定由光大

国际作为投资人,建设邳州市垃圾焚烧发电项目工程。项目总投

资 3.3亿元人民币 ,建设“2× 300td垃圾焚烧炉 +1× 12MW汽轮

发电机组”,其中环保设备及处理投资超过总投资的 ⒛%。

光大国际作为中国光大集团实业投资之旗舰公司,以环保能

源、环保水务和新能源三大领域为业务发展重点,己在大陆投资

250多亿元,落实项目70多个,包括苏州、宜兴、江阴、常州、

镇江、宿迁、惠东、新沂、济南、青岛、淄博、滨州、德州、砀

山、福州等地。截至 ⒛10年底,总设计规模为年处理生活垃圾

385万吨,总处理其他工业固体废物约 62.5万立方米;年处理

污水约 5.6亿立方米,基本实现一级 A排放标准。

光大环保,作为光大国际拓展绿色环保产业的投资管理平

台,遵循“一流的设计、一流的技术、一流的设备、—流的工艺、

一流的管理”,在江苏省内先后投资建设了苏州光大国家静脉产

业示范园、宜兴、江阴、常州、镇江、宿迁、江阴水务等多个环

保项目。从己建成项目来看,均与项目周边群众建立了良好的互

信关系,且项目运行高标准、严要求,至今未发生任何环境风险

问题。 ^

负责环境影响报告书编制的江苏省环境科学研究所具有建

设项目环境影响评价甲级资质,曾受委托对江苏省内多座生物质

发电、填埋场及大型电厂等项目进行环境影响评价,具有丰富的

环境影响评价经验。

作为邳州市 ⒛12年市政重点工程,通过邳州市垃圾焚烧发

电项目工程的建设,邳州市生活垃圾焚烧发电项目将真正进一步

提高邳州市环境承载力,实现邳州城市快速可持续健康发展,这

符合国家、江苏省、邳州市产业政策。邳州市垃圾焚烧发电项目

工程将确保工艺、技术先进性,焚烧尾气采用“半干法+干法反

应塔+SNCR脱硝+活性炭+布袋除尘器”方式处理,所有烟气排放

均执行欧盟 ⒛00标准。项目排水采用清污分流,渗滤液经渗滤

液处理站处理后接管至戴圩镇污水处理厂处理;炉渣综合利用、

飞灰螯合固化送至填埋厂处置,不会产生二次污染。预测表明该

工程正常排放的污染物对周围环境和环境保护目标的影响较小 P

环境风险可接受。在落实各项环保措施要求,严格执行环保“三

同时”前提条件下,本项目建设具有环境可行性。

三、会场提问及解释

根据听证会公众代表对建设项目环境影响报告书提出的问

题和意见,建设单位、环评单位、专家和政府有关部门将其归纳

为以下几类问题,分别进行了解释、说明和辩论,其要点如下 :

为什么要建垃圾处理Γ

建设单位吴永新对此问题做了如下回答 :1、我市每天还新

产生约 ω0吨的垃圾。无论从保护环境还是改变城乡卫生面貌考

虑,这些垃圾都需要采取有效的办法进行处理。垃圾的无害化处

理关系全市民生。2、邳州市目前仅有一个垃圾处理厂一彭河桥

垃圾处理厂,彭河桥垃圾处理厂的垃圾量目前己经饱和 ,堆积约

㈨万吨。3、垃圾的无序简易处理会严重影响的邳州市的环境 ,

影响人民的身体健康 ;4、目前无论是国内还是国际垃圾的无害

化、资源化、减量化处理的最好的方式是焚烧 ,而且现在的垃圾

焚烧技术已经相当成熟 :5、鉴于以上几个原因市政府决定邳州

市的垃圾处理选择焚烧发电的方式,通过对国内垃圾焚烧发电多

家企业的考察,我市最终选择了光大国际。

居否对鼠边环境有影昀 (恶臭钅体防轫

省住建部专家吴德水作出了回答:垃圾焚烧厂恶臭主要来源

于垃圾本身,基本发生在垃圾储坑、垃圾卸料大厅、渗沥液储坑

和焚烧炉等附近。为避免臭气外溢,本项目对垃圾储坑、垃圾卸

料大厅等主要臭气污染源采取下列控制措施:(1)采用压缩封闭

的自卸式垃圾运输车 ,并在垃圾焚烧厂主厂房卸料平台的进出口

处设置垃圾卸料门。本项目的垃圾运输线路与现有运输路线一

致,对沿线环境影响不大。(2)垃圾坑采用密闭结构,焚烧炉助

燃用的一次风从垃圾储坑顶部吸取,正常运行时垃圾坑保持微负

压状态以免臭气外逸。(3)对垃圾库规范操作管理,降低臭气产

生。利用抓斗对垃圾的搅拌翻动,可避免垃圾的厌氧发酵 ,减少

恶臭气体的产生。(4)利用封闭的残渣输送系统,对残渣储坑实

行密闭负压操作,臭气经风机送至垃圾储坑作为燃烧一次空气。

(5)运彳阶段,主要通过加强管理来对臭气进行控制,如尽量

减少全厂停产频率、一次抽风系统保持正常运转、进厂垃圾车采

用封闭式车辆、垃圾贮存池卸料门不用时关闭,使垃圾坑密闭化

等。(6)锅炉事故停运或检修时,垃圾储坑保持密闭,垃圾贮坑

排气需经除臭处理,换气次数约为 1~1.5次小日寸,采用活性炭

废气净化器装置除臭,除臭装置安装在垃圾坑旁的建筑物屋顶。

渗滤液及历幻囫鬯

江苏省环科院崔小爱作出回答 :本项目厂内排水系统采用清

污分流、雨污分流体制。锅炉排水作为灰渣冷却用水,不外排。

垃圾产生的渗滤液经自建的渗滤液处理设施预处理 ,主要处理工

序为,渗滤液处理采用“预处理+UASB厌氧反应器+MBR生化处理

系统+NF纳滤膜”工艺,确保污水预处理达到市政污水纳管标准

l),ph=6四后进市政污水管网送进戴圩污水处理厂统一处置。

其余清洗废水及生活废水直接排入市政污水管网。

达标捃卜放问题

东南大学建筑设计研究院苏凯作出了回答 :垃圾燃烧产生的

有害物资主要有二嗯英,酸性气体 S02,HCL,NOx,火因尘及重金属等 ,

邳州垃圾发电项目的烟气处理系统采用了“半干法+干法反应塔

+SNCR脱硝+活 J性炭+布袋除尘器”相结合的处理系统。 1.二嗯

英的源头控制:本项目采用 3T技术从源头削减、控制二嗯英的

产生。通过“三 T” 控制法,温度控制在 850°C以上,超过 2S,

高温的烟气充分扰动,产生湍流保证烟气无温度死角,这样垃圾

中的原生嗯英绝大部分得以分解 ,2、烟气采用了半干法+干法

反应塔经行脱酸处理,去除烟气中的 S02、 HCL等酸性气体;SNCR

脱硝装置是向炉膛内喷射一定量的氨水 ,对烟气中的 NOx进行脱

氮处理;活性炭喷射的目的是吸附烟尘中的重金属及进一步吸附

二嗯英;布袋除尘器主要是过滤烟尘,通过上述环保措施进行处

理后,烟气的各种排放指标将确保达到欧盟 ⒛00标准,这—目

前最高排放标准。

垃圾旨问题

邳州市城管局陈怀亚对此问题作出回答 ,光大国际必须严格

按照与邳州市政府在 3月 2日签署的特许经营权协议的要求对垃

圾电厂进行建设,邳州市政府会对垃圾发电项目从设计、建设及

运行管理进行全过程的监管,监管分为政府监管和公众监管。1、

政府的职能部门如安检、环保、卫生等部门在项目的审批、设计、

建设的过程进行严格监管,确保项目的建设高标准,项目运营后

政府的监管更会加大力度,派驻厂监督代表,确保污水、烟气达

标排放,与环保部门实时联网,接受政府 24小时监督,在厂区

门口电子显示屏上实时公布排放指标数据。2、公众监督,厂址

周边百姓随时随地对焚烧电厂进行监督,发现项目有违规行为或

污染环境的情况,可马上举报。也可选出代表定期或不定期的对

电厂的的运行情况进行监督,如检查项目环保设施是否正常运
