System and method of coprocessing civil kitchen wastewater and civil household garbage

Abstract

The invention relates to a system and a method of coprocessing civil kitchen wastewater and civil household garbage. The system comprises a civil household garbage collecting device, a civil kitchen wastewater indoor drainage system, a civil residence drainage pipe network, an urban municipal drainage pipe network, an urban sewage plant, a natural water body, a civil kitchen wastewater/household garbage centralized treatment device, an urban biogas comprehensive utilization system, a supernate comprehensive utilization system, an urban household garbage sorting and transferring system, an urban household garbage landfill, a solid waste comprehensive utilization system and a mixture comprehensive utilization system. The system governs household garbage from the source, transforms a scaled household garbage treatment mode into a civil micro household garbage treatment mode and turns the kitchen wastewater/household garbage into wealth, so that the utilization efficiency of urban sewage/household garbage can be improved, the waste incineration efficiency can be improved, the emission of exhaust gas of a garbage power plant and a garbage landfill is reduced, the garbage is gradually reduced to zero landfill of the garbage, and the urban fuel gas amount and the electricity consumption are reduced.

Description

technical field [0001] The invention relates to the fields of domestic sewage treatment and solid waste treatment, in particular to a system and method for co-processing resident kitchen wastewater and resident domestic garbage. Background technique [0002] The final flow of the existing domestic sewage treatment process of urban residents is to enter the urban sewage treatment plant, and the final destination of the domestic waste treatment process of residents is the landfill. Currently, the two systems operate independently, and domestic sewage and domestic waste cannot be processed together at the same time. deal with. [0003] Through this treatment system and method, people's garbage collection methods can be completely changed, so that kitchen garbage (food-related garbage, excluding bones, seafood shells, and corn cobs) can be easily collected within the city at the same time. etc.) are completely separated from other domestic wastes, and thoroughly solve the long-...
