Background

Waste is a product of human production and life. With the development of economy and the modernization of material consumption, the generation of garbage increases year by year, which results in serious environmental pollution and the invasion of a large amount of land, and thus, garbage disposal has been one of the major problems facing the solution of environmental pollution. At present, the treatment modes of garbage in China mainly include a landfill treatment method, a compost treatment method and an incineration treatment method.

The filling treatment method is to fill the garbage into large pits or depressions to restore the landform and maintain the ecological balance. The method has the defects that the land occupation amount is large (about 3m2 land is needed for 1T garbage landfill), secondary pollution is easily caused after the landfill, for example, underground water source pollution, harmful gas scattering and polluting the atmosphere everywhere, an enrichment ring band can be formed in the range of about 50km of the radius of a landfill site by harmful metal, methane gas generated by the fermentation of the landfill garbage is easy to cause explosion, and the like.

The composting method is to transport the garbage to rural areas for fertilizing. The method can effectively improve soil, has low treatment cost and large treatment capacity, but is limited to a small scale at present because a lot of useful substances are wasted without separation, and a lot of non-fertile field components, such as glass, metal and plastic, cause secondary pollution to the environment.

The incineration treatment method is to incinerate the garbage to reduce the volume and the weight of the garbage. The method has the main advantages that the landfill amount of the garbage can be effectively reduced, only about 10 percent of the initial volume of the garbage needs to be buried after incineration, and the energy can be recovered and part of the sintering slag can be recycled. However, in the prior art, the garbage incineration equipment has high manufacturing cost and certain requirement on the calorific value of the garbage, and if the structure of the garbage treatment equipment is unreasonable, harmful gas is generated in the incineration process, so that secondary pollution is caused.
