In recent years, the development of the environmental protection field, especially the guiding thought, in China gradually progresses from reduction to harmlessness to recycling. Under the guiding idea of resource utilization, the compost is used as a traditional solid garbage treatment process, and the importance of the compost is highlighted again. At present, the compost mainly takes organic garbage which is easy to degrade and harmless to the environment after degradation and is rich in N, P and other elements as raw materials.
Wherein the content of degradable organic matter components in the municipal solid waste is more than 56%, and the organic matter can be separated and aerobically composted. The organic matter source is mainly kitchen garbage and kitchen garbage. The kitchen waste has low salt content, good fertility when used as a composting raw material, relatively low invalid salt content, and is not easy to cause land salinization, so the kitchen waste is very suitable to be used as the composting raw material. The compost of livestock and poultry manure in rural garbage has a long history and is an excellent compost raw material. The aerobic composting is characterized by fast decomposition speed, short composting period and thorough degradation.
