Embodiment Construction

[0032] The present invention classifies the urban garbage, performs comprehensive harmless treatment, regenerates and comprehensively recycles the waste, and completely solves the secondary pollution of urban garbage, and the landfill method of existing urban garbage occupies a large amount of land and pollutes the environment and groundwater resources. And turn harm into profit, turn waste into wealth, make the comprehensive management of municipal waste form a virtuous economic industry chain (see accompanying drawing). The specific steps of its classification and resource reuse are as follows:

[0033] The first step: transport the urban waste to the waste treatment plant by the waste transport trucks of different types of waste scattered in every corner of the city.

[0034] Step 2: Register and classify all kinds of garbage transported to the garbage treatment plant, and divide them into eight categories, namely: municipal solid waste, medical waste, branches and straw, ...

Abstract

The invention relates to a comprehensive treatment utilization technology for municipal domestic waste, which belongs to the technical field of treating and recycling municipal waste; the technology is as follows: the municipal waste is transported to a waste treatment plant so as to carry out harmless treatment, then is classified into eight kinds, that is, the municipal domestic waste, medical waste, branches and straws, floater on water surface, construction waste, aquatic plant, urban night soil and market waste, and is transported to a department belonging to one kind so as to be treated and recycled. The technology of the invention solves the problems of occupying a lot of lands, and polluting environment and groundwater resources caused by the landfill mode which is adopted to treat the municipal waste for a long time, solves the problems in municipal solid waste incineration that dioxin, a carcinogenesis gas, is released into air and 40 percent of waste residues still need to be land-filled, so that lands still needs to be occupied; therefore, the technology can change the municipal waste into valuables, recycle natural resources, give full play to the value of resource recycling, and realize the measures advocated by the country such as 'waste reduction', 'resource recycling' and 'harmlessness', thus being suitable for waste treatment in different cities.

Description

Technical field: [0001] The invention relates to a technology for comprehensive treatment and utilization of urban domestic garbage, which belongs to the technical field of classification, comprehensive treatment and resource recycling of urban garbage. Background technique: [0002] In recent years, the increasing amount of urban waste has become an urgent problem to be solved in all countries in the world, and our country is no exception. According to the current level of resource consumption and pollution control in our country, the pollution load will increase by 4-5 times, and the daily output of urban waste in our country is still increasing at a rate of 15% every year. If no treatment is done, no sanitary landfill will be made. It will seriously pollute the environment and produce secondary pollution, occupy a large amount of arable land, and waste a large amount of misplaced natural resources. It is estimated that in the next 15 years, my country's population will r...
