Description
Technical Field
The invention relates to the technical field of garbage treatment, in particular to a garbage classification treatment comprehensive utilization method and application.
Background
With the development of social productivity, the variety and yield of wastes are increasing, and the severity of garbage pollution and the resource availability of part of materials have become hot issues of global concern. In the face of the reality of the flood of solid wastes, the view of all countries in the world does not stay on the problem of how to control and destroy urban solid wastes, but adopts active attitude and beneficial measures to carry out scientific treatment, recycles the urban solid wastes, and classifies the urban solid wastes as 'second resources'.
The municipal solid waste is solid waste generated in the processes of resident life, commercial activities, municipal construction and maintenance, office work and the like, and is generally divided into municipal domestic waste, industrial solid waste and harmful substances. From an ecological perspective, municipal solid waste is inherently a source of pollution, while from a resource perspective, it is the only growing resource on earth. Facing two problems of worsening of garbage pollution and shortage of natural resources, how to reasonably treat garbage and recycle the garbage becomes an increasingly important focus in the process of urbanization in China.
At present, environmental pollution caused by various wastes and control of the environmental pollution become a major environmental problem commonly faced by countries in the world; because the selection of the municipal solid waste treatment mode and technology is influenced by the factors such as waste components, economic development level, energy structure, natural conditions, traditional habits and the like, the selection of each municipal solid waste treatment technology is different, and a unified and fixed mode does not exist. At present, landfill is also a garbage disposal mode which is commonly adopted at home and abroad, and the garbage disposal mode, garbage incineration and garbage compost are listed as three most garbage disposal modes which are adopted by various countries in the world at present.
The garbage treatment development in China is late, the 20 th century is just beginning in the early 90 th, the domestic garbage treatment in small towns in China is mainly simple landfill or direct stacking, the biggest defects are that the site selection is difficult, the occupied area is large, and the generated leachate and landfill gas pollute underground water, atmosphere and the like, so that land occupation, environment pollution, underground water pollution, river pollution and the like are caused.
Garbage compost is developed earlier in foreign developed countries and starts to be simpler static aerobic compost. The domestic composting technology is also developed earlier, the economy for China is laggard before decades, the agriculture rarely uses chemical fertilizers, organic fertilizers are main agricultural fertilizers, the municipal domestic garbage (mainly vegetable leaves and coal ash) is mainly subjected to simple composting, and the treated products are sold to rural areas and are in short supply. Along with the development of economy and the improvement of the living standard of residents, the quantity of non-degradable substances in garbage is increased, the composting difficulty is increased, the composting quality is poor, and the sale of the compost is poor. On the other hand, with the increase of the supply of high-efficiency fertilizers, farmers are reluctant to spend money to buy garbage compost with low fertilizer efficiency. Therefore, garbage compost has been going down the slope since the late 80 s of the 20 th century. In recent years, with the improvement of awareness of environmental protection and resource recycling, a batch of garbage compost plants with higher mechanization degree are built in some cities, but because the domestic garbage is not classified and collected, the sorting effect of some screening devices configured in the compost plants on the mixed garbage is not ideal, and the production is stopped.
At present, the garbage disposal industry in China is still in the beginning stage, and the garbage disposal of a plurality of large and medium-sized cities is just started. From the national scale, only a few small towns develop garbage disposal, such as the eastern developed small towns and national key watersheds (such as the three gorges reservoir region and the like), the collection and disposal of the garbage in the small towns are still basically blank in most places, and the garbage is basically unordered in management. Therefore, the phenomenon that the plastic trees hang up in winter still at the roadside of the melon rind in summer in cities and towns is caused. The daily garbage yield of each small town in each region is 0.8-1.3kg, and the total average garbage yield is 10kg/d. Therefore, the harmless, resource and reduction treatment of the small-town garbage is imperative.
