"Garbage Disposal" Environment and Us PPT Courseware 2

Option One

landfill

A simple landfill is to find an open space, dig a big pit, dump the garbage into it, and then cover it with soil.

Let me experiment:

Landfilling garbage is the most commonly used method of garbage disposal at present. Let us simulate such an experiment and see what happens?

Kind tips:

Experimental steps:

①Put in water first

②Put in the No. 1 material bag (slightly larger stones) and spread it as flat as possible;

③Put in the red-dyed napkin and place it as close to the wall of the glass container as possible;

④Put in the No. 2 material bag (slightly smaller stones);

⑤Sprinkle water, the speed should not be too fast;

⑥ Experiment, observe and record while doing so.

summary:

If the garbage is simply landfilled, the sewage in the garbage will spread, and the sewage will spread to the surrounding soil. If vegetables and food are grown in the contaminated soil, would you be willing to buy them and eat them?

What’s even more frightening is that as the sewage in the garbage spreads, it will also pollute the groundwater. And groundwater will flow around, so the germs and bacteria in the sewage will spread to a larger area with the groundwater, endangering people's health. Therefore, the spread of sewage in the garbage is a very serious hazard.

Liner: Separates the dump house from the surrounding soil.

Garbage filtering collection pool and treatment pool: The water that seeps into the garbage house from the ground and is contaminated by garbage is collected for treatment.

Monitoring Wells: Monitor soil and groundwater conditions near landfills at all times.

Gas discharge pipe: discharges flammable gases and toxic gases.

Option II

burn

Incineration is another common method of disposing of waste, which involves burning it in an incinerator.

The Deqing Canon waste incineration power plant located in Jiayuan Village, Deqing City, is an environmental protection project invested by China Power New Energy Development Co., Ltd. with a RMB 120 million investment. It is listed as a key project in Deqing County.

It is the first waste incineration power generation project built by China Power New Energy in Zhejiang.

It mainly handles domestic waste from 11 towns and development zones in Deqing County. The waste incineration equipment and flue gas treatment technology used are the most advanced in the country.

On March 31, grid connection for power generation was successfully completed.
