Embodiment Construction

[0009] The process invention is composed of two subsystems of urban sewage treatment and urban domestic garbage treatment.

[0010] The domestic waste entering the factory enters the pre-sorting field, and the recyclables are sorted out and the landfill is drained at the same time, and then enters the first screening, the underscreen enters the second screening, and the overscreen enters the aerobic waste through magnetic separation. For composting, oxygen is supplied by a high-pressure fan, aerobic composting, sorting and draining, and leachate produced by the bin to be burned enter the sewage treatment system. Deodorization pool deodorization. After aerobic composting, the primary compost goes into three screenings, and the under-sieving is subjected to secondary composting and aging, and the matured finished compost is screened four times, and the under-sieving can be sold directly or made into finished fertilizer after removing impurities. The sieve of the first screening...

Abstract

The invention discloses an art for comprehensive processing urban sewage and urban domestic refuse. The said art combines single urban sewage processing and single urban domestic refuse processing together to compensate for the shortage of single processing art. The urban sewage processing is carried out by oxidation ditch method, and the urban domestic refuse processing is carried out by the comprehensive processing method of 'three parts in one piece'. The said processing comprises: burning the sludge refuse produced by sewage processing in an incinerator, conveying the sludge refuse to engage in burning or produce aerobic compost in the refuse processing, and conveying the leachate produced by refuse processing to the sewage processing stage.

Description

Technical field [0001] The invention relates to a process for comprehensively treating urban sewage and domestic garbage. It organically combines a single urban sewage treatment and a single urban domestic garbage treatment for comprehensive treatment, and achieves the purpose of making up for the shortcomings of a single treatment process. Background technique [0002] At present, various processes of urban sewage treatment in my country have been relatively mature, such as activated sludge method, oxidation ditch method, biological filter method, biological turntable method, etc., but they are all single sewage treatment, and their disadvantage is that the dirt removed by the grid And the sludge generated during the treatment process cannot be effectively treated. Similarly, the treatment of urban domestic waste in my country is also a single domestic waste treatment. The disadvantage is that the leachate generated during the treatment process must be transported to the se...
