Abstract

The invention provides an efficient sewage treatment system. The efficient sewage treatment system comprises a pretreatment building structure, a biological tank, a membrane tank and a disinfecting tank which are communicated through pipelines; an anaerobic region, an anoxic region and an aerobic region are sequentially arranged in the biological tank along the flow direction; the membrane tank comprises a membrane tank wall body, a membrane tank aerobic region, a membrane region and a sludge reflux region are sequentially arranged in the membrane tank wall body, and the membrane tank aerobic region and the membrane region are separated through a first partition wall; the membrane region and the sludge reflux region are separated through a second partition wall; a water inlet pipe is arranged on the membrane tank wall body of the membrane tank aerobic region; multiple groups of micro-hole aeration devices are arranged in the membrane tank aerobic region; multiple groups of membrane units are arranged in the membrane region; two groups of adjacent membrane units are separated through a wall body. The efficient sewage treatment system is remolded by virtue of an existing sewage treatment plant; when the occupied area is not increased and the production is not stopped, the water quality of effluent is improved, the treatment capacity is doubled, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an efficient sewage treatment system. Background technique [0002] The problem of water resources is a major problem in today's society. It seriously affects the environment and restricts the sustainable development of economy and society. Especially at the current stage, a large amount of sewage is discharged outside, causing a greater burden on the sewage treatment work of the sewage treatment plant, and urgently needs to be improved to meet the greater demand. [0003] At present, most of the sewage water treatment process still adopts conventional treatment, including pretreatment, biological pool, membrane pool, disinfection and other procedures, among which the membrane pool is a relatively important part. It is one of the current problems to be solved urgently to improve the water treatment efficiency under the size of the structure. Contents of the invention ...
