Background
The household garbage has great resource utilization value, and the classified recycling has very important significance for promoting the reduction, harmlessness and resource utilization of the household garbage. The classification of garbage in China begins in the 90 s of the 20 th century, however, due to the reasons of weak policy constraint, weak public, and unsound garbage classification treatment circulation chain, the classification of garbage in most places only stays at the source throwing stage, and meanwhile, the phenomenon of first classification and then mixing in the garbage transportation process brings many problems to the subsequent garbage treatment. The treatment mode of the garbage in China mainly adopts sanitary landfill as a main policy, is assisted by other treatment methods of incineration and composting, and the mixed and collected household garbage enters a garbage landfill to cause resource loss and waste. With the rapid development of social economy, the yield of domestic garbage in China is continuously improved, according to relevant statistics, the annual yield of domestic garbage in China is about 4 hundred million tons at present, the daily yield is increased by about 8% every year, the traditional garbage throwing and treatment can not meet the current garbage treatment requirement, the requirement of constructing a resource-saving and environment-friendly society is accelerated in the face of such a severe form, a series of mandatory regulations are developed in China to comprehensively push the garbage classification work, and the Chinese garbage classification enters a mandatory era.
Researches show that wet garbage such as kitchen garbage, fruit and vegetable garbage and the like in the municipal solid waste in China accounts for 50% -60%, and the garbage is easy to decay and smell, and flies and mosquitoes are bred, so that the garbage can bring great negative effects on the treatment and utilization of other garbage. Because the population base of China is large, the garbage yield is increased day by day, and detailed garbage classification can not be popularized in a short period, so that the household garbage can be roughly classified into dry and wet garbage for recycling and treating, the garbage clearing and transporting amount and the final treating amount are effectively reduced, and the garbage recycling utilization efficiency is greatly improved.
