WATER TREATMENT &

WASTE MANAGEMENT

Gimnazjum nr 1 im.T.Kościuszki w Zawierciu

Household waste

•plastic,

•paper,

• glass,

•metal,

•organic waste,

• chemicals.

Biodegradable waste: food and kitchen waste, green waste, paper (can

also be recycled).

Recyclable materials: paper, glass, bottles, cans,

metals, certain plastics, fabrics, clothes, batteries

etc.

Inert waste: construction and demolition waste,

rocks, debris.

The question is: what can we do???

We can:

REDUCE,

REUSE,

RECYCLE.

What is the best way to dispose of waste?

•Waste incineration is the method of neutralising municipal solid waste; (energy is gain in this

process)

•For many years domestic waste is incinerated in

company - MEDIEN PARTNER RECYKLING in

Poland

COMPOSTING

•Composting of municipal solid waste is the method

of organic matter recovery.

•Compost is organic matter that has been decomposed and recycled as a fertilizer.

Compost can be rich in nutrients and it’s a key ingredient in organic

farming.

It is usually used in gardens.

RECYCLING

Recycling is a process of:

•changing materials (waste) into new products to

prevent waste of potentially useful

materials,

• reducing energy usage,

• reducing air pollution (from incineration) and

water pollution (from land filling)

WASTE SORTING

Waste sorting is the process by which waste is separated into different

elements .

colourful glass, jars, bottles and glass packaging.

Paper, newspapers, notebooks, paper bags, carboard.

glass bottles, cosmetic packaging.

WILD waste dumps

Wild waste dumps

come into being in the forestes and near our

rivers and cause dangerous water and soil

contamination.

Wild waste dump is the source of:

• dangerous soil pollution,

• water contamination,

• epidemic of dangerous illness

• weak trees condition

• biogases lightening

• emision of CO2, NH4, H2S

• ecosystems disturbing

•destroying the natural environment

• deformation of the ground

Ecological Campaigns in Zawiercie

An expansion of Municipal Waste Company in

Zawiercie.

The main aim of this project was to reduce the

amount of waste and increase an ecological

awarness.

ECOLOGICAL CAMPAIGNS IN OUR SCHOOL

• In 2012 our school took part in ecological

competition

„ BATTERIES COLLECTION” – 12th

edition. We won the first prize and were very proud.

Every year we also

„Clean the World”

Water treatment

The Sewage Treatment Farm in Zawiercie

The Sewage Treatment Farm in Zawiercie was built at the turn of the 1960s and 1970s, and was

modernized in 1993-1998 and for second time in 2008-2009.

Its objective is to purify sewage in a process of removing

impurities from wastewater and

household sewage both runoff

(effluents), domestic, commercial and institutional.

It includes mechanical and biological processes to remove

chemical and biological contaminants.

During the first mechanical treatment process of

filtration constant pieces and sediments are

removed by using all kinds of bars and sieves.

Biological treatment process is based on nitrification and denitrification The purpose of this process is to reduce the amount of nitrogen,

phosphate and sediments. After that treated sewage is

discharged to the environment – the Warta River.

In this technological process two kinds of sediments come

into being, then they are treated in the process of fermentation in a closed

fermentation tank. The final product of this process is

biogas that can be used as a fuel, for any heating purpose.

Our trip to the sewage treatment farm

In May our guests from Spain, Malta, Tukey, Slovenia, Italy, Portugal, France, Romania

and pupils from our school visited The Sewage Treatment Farm.

We could learn about biological and mechanical

processes of puryfing water.
