Integrated membrane bioreactor for sewage deep denitrification

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a sewage deep denitrification integrated membrane bioreactor which comprises a tank body and a membrane component, the tank body is internally provided with an anoxic filler area, the inner wall of the tank body is fixedly connected with an annular baffle plate, the annular baffle plate is internally provided with an aerobic filler area, and the bottom end of the inner wall of the tank body is provided with a group of aeration discs; the side wall of the tank body is communicated with a group of feeding pipes; the rotating shaft is driven by the servo motor to rotate forwards and backwards repeatedly, when the rotating shaft rotates forwards, the connecting wire is wound on the rotating shaft, the connecting wire pulls the adjusting pipe to move upwards, the connecting disc moves upwards, water sprayed out of the water outlet holes can be comprehensively sprayed to the membrane assembly, and when the rotating shaft rotates backwards, the connecting wire is loosened, so that the water outlet holes can be completely sprayed to the membrane assembly. At the moment, the connecting disc moves downwards, the connecting disc is driven to move up and down repeatedly through the connecting wire, so that water discharged from the water outlet hole flushes the membrane module repeatedly, and the cleaning effect on the membrane module is greatly improved.
