Description
Technical Field

Therefore, the traditional sewage pipe network collection method has obvious defects, such as (1) the cost of the sewage pipe network system for communicating each household is high; (2) a large amount of power is consumed for transportation, and the cost is high; (3) sewage is easy to leak in pipe network transportation, and distributed residents are difficult to maintain; therefore, with the development of sewage treatment technology in China, the technology for treating sewage in rural areas is gradually developed, namely, the distributed sewage treatment technology. The technology can be subdivided into: a physicochemical treatment technology; biological treatment technology; ecological treatment technology;
the traditional treatment method of the rural domestic garbage can be divided into (1) simple composting, the livestock manure can be consumed by vast rural land after the simple composting treatment and (2) burning method, and the burning method is carried out in the open air or simply buried. The secondary pollution hidden trouble brought by the perishable garbage with a larger proportion (higher than 50%) in rural domestic garbage components according to the traditional simple treatment mode is highlighted, the perishable garbage is separated out and treated on site, the collecting and transporting treatment cost of the domestic garbage can be greatly reduced, and the on-site composting treatment is an effective measure for realizing the 'three-transformation' of the rural perishable garbage.
At present, the common idea of the rural domestic garbage and domestic sewage treatment technology is to separately treat the rural domestic garbage and the domestic sewage, a unified treatment process is not available, the cooperativity between the rural domestic garbage and the domestic sewage is neglected, and a large amount of energy is wasted. On the contrary, the excellent heat preservation performance of the soil can be used as a constant temperature material of the aerobic bioreactor to prevent temperature fault, insufficient aerobic reaction and the like. And abundant microbial activities in the soil can provide natural decomposition for odor attempted by the aerobic reactor. The microorganism activity in the soil is simultaneously provided with continuous carbon dioxide for the upper layer plants to promote the growth of the plants.
