The domestic garbage treatment project is first collection-transportation-garbage building-transfer station-garbage dump. When you arrive at the garbage dump, it depends on the type of garbage dump, whether it is a landfill, an incineration plant, a composting plant, or a comprehensive treatment plant. After the landfill is weighed, it is poured directly into the pit and buried. After the incineration plant is weighed, a certain proportion of coal is mixed and then poured into the incinerator to generate electricity. After the compost plant is screened, the organic matter is piled up to make fertilizer. Now the composting plant has basically withdrawn from the waste treatment industry.

At present, most domestic treatment processes are landfills, but landfills occupies a lot of land and secondary pollution is large. Now waste incineration power plants are being built all over the country. This process can reduce the amount of waste, but the investment is very large and the operating cost It is also very high. It takes more than 100 yuan to process a ton of garbage. The little electricity produced is nothing. What is more important is that the incineration power generation process produces dioxin gas that is 900 times more toxic than arsenic.

Domestic waste treatment refers to the treatment of various wastes discharged by residents, including processing for transportation and recycling. The purpose of treatment is to make the shape and composition of the garbage more suitable for disposal requirements. For example, in order to facilitate transportation and reduce costs, compression treatment is often carried out; in order to recover useful substances, it is often necessary to undergo crushing treatment and sorting treatment. If incineration or landfilling is used as the final disposal method, it is also necessary to properly crush and sort the garbage first to make the disposal more effective.
