Abstract

The invention belongs to the technical field of sewage treatment, and discloses a rural domestic sewage treatment device, which comprises an upper pool body and a lower pool body. The lower pool bodycomprises a septic unit, and a sewage treatment unit and an adjusting unit which are arranged around the septic unit; the sewage treatment unit comprises a first anoxic unit, a first aerobic unit, a second anoxic unit, a second aerobic unit and a precipitation unit which are sequentially communicated, and a water collecting tank connected with a water outlet pipe is arranged at the top of the precipitation unit; a water inlet pipe is arranged on the septic unit, an airlift pump and an airlift pump water outlet pipe are arranged in the septic unit, a gas ejector pipe is arranged on the airliftpump, the airlift pump is connected with aeration ring pipes in the two aerobic units through aeration pipelines, and the precipitation unit and the two aerobic units are communicated with the two anoxic units through a sludge return pipeline by utilizing the airlift pump. The sewage treatment device is compact and reasonable in structure, good in treatment effect, low in mud suction work and energy-saving, treated discharge water can be used for irrigation, the problems that rural domestic sewage is dispersed and is not convenient to treat are solved, and waste can be turned into wealth.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a rural domestic sewage treatment device. Background technique [0002] With the progress of society, the living conditions in rural areas are getting better and better, and the types and concentrations of sewage pollutants produced in the living process are increasing. However, the location of each village is different. Some rural areas are far away from sewage treatment plants. Rural sewage collection and treatment are difficult and often costly. Some farmers have set up septic tanks for preliminary treatment of domestic sewage, the effect is limited, and the cleaning work is relatively frequent. Other rural areas have set up sewage treatment facilities, and these facilities are set up separately from the septic tanks, usually occupying a large area. This has been limited in the promotion process of on-site treatment of domestic sewage in rural areas: the ...
