An anaerobic membrane bioreactor for domestic sewage treatment

Abstract

The invention relates to an anaerobic membrane bioreactor for treatment of domestic sewage, relates to an anaerobic membrane bioreactor, and aims to solve problems that a conventional membrane bioreactor is high in membrane pollution speed, short in membrane pollution period and high in operation cost, and the application of the anaerobic membrane bioreactor is limited. According to the anaerobic membrane bioreactor, a round membrane component is arranged in an anaerobic reaction component, a water inlet tank is communicated with a water inlet of the anaerobic reaction component through a guide pipe, a peristaltic pump is communicated with the round membrane component through a connection guide pipe, and a vacuum pressure gauge is arranged on the guide pipe between the round membrane component and the peristaltic pump; the lower part of a stirring device is arranged in the round membrane component, and a control switch of the stirring device and a control switch of the peristaltic pump are controlled by the same time relay; a gas collecting bag is connected with a gas outlet of the anaerobic reaction component through a guide pipe; and a liquid level contact probe is arranged on a terminal of a liquid level relay, and a temperature probe is arranged on a terminal of a temperature controller. The anaerobic membrane bioreactor is used for treating domestic sewage.

Description

technical field

[0001] The invention relates to an anaerobic membrane bioreactor, in particular to an anaerobic membrane bioreactor used for domestic sewage treatment, and belongs to the technical field of sewage treatment. Background technique

[0002] Membrane bioreactor is a new sewage treatment process with the most development potential and application prospect developed at the end of the 20th century. It integrates high-efficiency membrane separation and biological treatment technology, and effectively realizes solid-liquid separation. Membrane bioreactor realizes the complete separation of hydraulic retention time and sludge retention time, and has the advantages of high effluent quality standard, stable quality, small footprint, and less residual sludge.

[0003] Anaerobic membrane biological reaction technology can not only solve the problems of low anaerobic treatment effect and serious sludge loss, but also use biogas to generate electricity, effectively reducing ...
