First, the generation of leachate and its treatment significance

Incineration is adopted for municipal waste treatment. With the increasing amount of garbage, a large amount of liquid will be produced in the combustion process, including toxic substances whose properties change under high temperature environment. The liquid content of the garbage in the kitchen is large, and the leachate produced in the incineration process is also large.

Piled up before burning rubbish is centralized, internal waste water are generated from the decomposition of fermentation, the leachate contains a lot of pollutants, the concentration and high, if not treated is wanton stream drip, will cause serious environmental pollution, pollution by leachate of the land is not conducive to the growth of plants, and city garbage disposal, leachate treatment is needed after burning, otherwise it will cause secondary pollution.

The leachate also gives off odor and pollutes the air. It is urgent to its management, water source, land, air and so on are affected by its, this also is what needs to be solved key at present. The significance of sewage treatment is mainly in the following three aspects. Water is a precious natural resource. Without treatment and discharge of water bodies, the deterioration of the environment endangers production and threatens people's health.

Second, the nature of leachate

Leachate mainly contains oil pollution and heavy metal pollution substances, if not treated, directly discharged into the river, will lead to the overall water quality will be affected, people's health and ecosystem balance will be affected. Therefore, leachate is a hazardous substance, and there are strict requirements for its treatment and discharge. It is also the focus of environmental protection work at present.

Leachate accounted for about 50% of moisture content, most of the rest of the material is the kitchen waste, oily substances more, also can produce odor after fermentation, understand its nature, can undertake the leachate treatment, from the aspect of all features that contain harmful substances, after treating leachate science for emissions, reduce the secondary pollution of the environment opportunity, the following will also discussing the specific measures of pollution control.
