Abstract

The invention belongs to the technical field of sewage treatment equipment, and particularly relates to a device and process of distributed domestic sewage treatment. The device comprises a cylindrical pool body, wherein the cylindrical pool body is internally provided with an anoxic tank, an aerobic tank and an inverted truncated conical tank, an air inlet pipe box is connected with an air inletpipe and a blower, and a water inlet pipe is arranged at the top of the left side of the anoxic tank, a water outlet is formed in the bottom of the right side of the anoxic tank, and a perforated aeration pipe is arranged in the anoxic tank; the aerobic tank communicates with the water outlet of the anoxic tank, a microporous aeration disc and a third gas stripping pump are arranged at the bottomof the aerobic tank, and a gap is formed in the side wall of the bottom of the inverted truncated conical tank; and a first gas stripping pump is also arranged at the bottom of the inverted truncatedconical tank, the outlet end of the first gas stripping pump is connected with a sludge returning pipe, the free end of the sludge returning pipe communicates with the anoxic tank, and a water outletpipe is arranged at the center of the top of the inverted truncated conical tank. The invention aims to solve the problems, which are caused by the structural defects of an existing sewage treatment device, of a poor effect of biological removal of nitrogen and phosphorus, poor quality of effluent, large floor space and no benefits for promotion of a distributed sewage treatment technology.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a distributed domestic sewage treatment equipment and a process thereof. Background technique [0002] With the rapid development of economy and society, people's living standards have improved significantly, which has driven the demand for sewage treatment. Sewage produced in the process of human life is one of the main sources of water pollution. Therefore, in order to alleviate the increasingly serious problem of water pollution, it is first necessary to treat the sewage produced in people's life in a harmless manner. In terms of treatment methods, it can be divided into centralized sewage treatment and decentralized sewage treatment. [0003] Centralized sewage treatment refers to the treatment of mixed wastewater such as urban domestic sewage collected by the municipal pipe network, industrial wastewater that has been pretreated and discharged...
