Abstract

The invention discloses a sewage treatment device. The sewage treatment device comprises a regulating tank, an anoxic zone, an anaerobic zone, a mud membrane symbiotic aerobic zone and a solid-liquidseparation zone which are sequentially communicated. The regulating tank is communicated with an inlet pipe, and a supernatant of the solid-liquid separation zone is in communication with the outlet pipe. A one-way channel for unidirectional reflux of a mixed solution in the aerobic zone to the anoxic zone is provided at the bottom of the mud membrane symbiotic aerobic zone. A one-way channel forsludge to flow back to the anoxic zone is arranged at a bottom sludge sedimentation zone in the solid-liquid separation zone. The sewage treatment device is a decentralized double-pass mud membrane symbiotic integrated sewage treatment device, can make the mixed solution and the sludge have no power to flow back and achieve unattended automatic operation, is stable and reliable in treatment effect, has the advantages of simple structure, less land occupation, low investment, low energy consumption, low operating cost and convenient management, and is suitable for rural domestic sewage treatment in economically underdeveloped areas.

Description

technical field [0001] The invention belongs to the sewage treatment technology, and in particular relates to a distributed double-pass mud film symbiosis integrated sewage treatment equipment. Background technique [0002] Carrying out rural domestic sewage treatment is an important task to improve the quality of water environment in rural areas. Compared with cities, the treatment of domestic sewage in rural areas has the following characteristics: due to the relatively weak rural economic base, there is not much funding for water pollution control; the supporting infrastructure is poor, and there are no corresponding testing facilities and monitoring personnel; a single sewage treatment facility The scale is small, but the number of facilities is huge, and the operation and supervision are difficult. According to the analysis of data in the 2010 "China Urban and Rural Construction Statistical Yearbook", my country's urban sewage treatment rate has reached 87%, the county...
