1. Landfill treatment: Landfill is an effective way to absorb a large amount of municipal solid waste, and it is also the final treatment method for the residues of all waste treatment processes. Direct landfill is generally used in China. The so-called direct landfill method is to fill the garbage into the prepared pit, cover it and compact, make it undergo biological, physical and chemical changes, decompose organic matter, and achieve the purpose of reduction and harmlessness.

2. Composting treatment: pile up domestic garbage into piles, keep it at 70℃ for storage and fermentation, and decompose organic matter into inorganic nutrients with the help of the ability of microorganisms in the garbage to decompose. After the domestic waste treatment equipment is composted, the domestic waste becomes hygienic and odorless humus. It not only solves the way out of garbage, but also achieves the purpose of recycling. However, the amount of compost of domestic garbage is large, and the nutrient content is low. Long-term use can easily cause soil compaction and deterioration of groundwater quality, so the scale of composting is not easy to be too large.

3. Incineration treatment: The incineration method is a method in which the garbage is placed in a high-temperature furnace to fully oxidize the combustible components, and the heat generated is used for power generation and heating. During incineration, garbage with a humidity of 7% can be turned into dry solids for incineration. The incineration efficiency is more than 95%. At the same time, the high temperature energy on the surface of the incinerator converts heat energy into steam, which can be used for heating, air conditioning equipment, and steam turbine power generation. . The advantage of incineration treatment is that the reduction effect is good, the volume of the residue after incineration is reduced by more than 90%, the weight is reduced by more than 80%, and the treatment is thorough.
