The invention relates to a membrane biological electrochemical reactor device with high-quality effluent and low membrane pollution, relates to the field of sewage treatment and is used for solving the problems of serious MBR (Membrane Bio-Reactor) membrane pollution, low nitrogen removal rate, poor treatment effect on sewage which is difficult to degrade and the like. The reactor device comprises a water box, a water-inflow peristaltic pump, an MFC (Microfunction Circuit) anode chamber, a stainless steel flat plate membrane, an MBR reactor, a conducting wire, an external resistor, an aeration head, an air flowmeter, an air compressor, a vacuum pressure gauge, a backflow peristaltic pump and an effluent peristaltic pump. As the reactor device is used, the sewage firstly enters the anaerobic MFC anode, and anaerobic electricity generating microorganisms perform hydrolytic acidification pretreatment; then the sewage enters the MBR, and the partial effluent are enabled to flow back into the anaerobic anode chamber, so that the denitrification of the sewage is further performed. Therefore, the energy source recovery and in-situ utilization of the electric energy performed by the MFC, the effective control of the membrane pollution and the efficient treatment of the sewage are realized. As a result, the reactor device is obvious in economic and environmental benefits. The reactor device provided by the invention is applied to the field of the sewage treatment.
