Rural domestic sewage disposal plant

Abstract

The invention provides a rural domestic sewage disposal plant, mainly comprising a pool body with upper part thereof arranged with a water inlet pipe and a water outlet pipe. The invention is characterised in that: lower part of the pool body is an active sludge area and the upper part of the pool body is a light filter material area; water inlet pipe communicates with the active sludge area at the lower part of the pool body; and the water outlet pipe is arranged above the filter material area. Positive effects of the invention lie in that: multiple anaerobic biological treating technique combines anaerobic active sludge process and anaerobic contact process, effectively remove pollutants and has good water quality; the upper layer of the multiple anaerobic biological treating device is filled with light filter material which can well filter, prevent sludge flowing and reduce concentration of suspended solid of the disposed water; the multiple anaerobic biological treating device takes up small area, has no power consumed, has simple operation, convenient management and meets requirement of rural domestic sewage disposal.

Description

technical field [0001] The invention relates to the technical field of wastewater biological treatment, in particular to a rural domestic sewage treatment device and treatment method. Background technique: [0002] my country's "Eleventh Five-Year Plan" put forward the major historical task of building a new socialist countryside, and clarified the construction goals of "development of production, affluent life, civilized rural customs, clean and tidy village appearance, and democratic management". The wanton discharge of rural domestic sewage is an important factor that causes rural environmental pollution, endangers the physical and mental health of rural residents, and affects the development of rural economy. Strengthening the treatment of rural domestic sewage is the basis for improving the appearance and appearance of rural villages, the prerequisite for improving the living standards of rural residents, and an important part of the construction of a new socialist coun...
