Abstract

The invention relates to the field of water treatment, and in particular relates to a membrane bioreactor and microorganism fuel battery pack combination system. According to the system, the problems of high electric field treatment cost and suppression on microorganism activity of the conventional process for controlling membrane pollution by an additional electric field and the problem about sludge treatment are solved. A plurality of membrane wires are connected to a water collection pipe; the lower end of each membrane wire is closed; the other end of each first titanium wire extends out of the upper end of each membrane wire and penetrates into the water collection pipe; a plurality of first titanium wires are connected with one another and led out from a titanium wire outlet and then connected with one end of a lead wire; the other end of the lead wire is connected with the positive electrode of a microorganism fuel battery pack through a second titanium wire; a stainless steel net or a titanium metal net is connected with the negative electrode of the microorganism fuel battery pack through the lead wire and the second titanium wire; a membrane bioreactor is communicated with the microorganism fuel battery pack; and the microorganism fuel battery pack is communicated with the membrane bioreactor. The membrane bioreactor and microorganism fuel battery pack combination system is used for treating sewage.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a combined system of a membrane bioreactor and a microbial fuel cell group. Background technique [0002] Membrane bioreactor (Membrane bioreactor, MBR) combines the activated sludge method with membrane separation technology for the treatment and reuse of domestic sewage and industrial sewage. It is a very attractive treatment process. However, membrane fouling and its The resulting increase in maintenance and operating costs limits the wide application of MBR, and is still one of the most challenging issues facing the development of MBR. Research in this field at home and abroad mainly focuses on three aspects: membrane materials and membranes Component structure, reactor operating conditions, influent and activated sludge mixture characteristics. MBR membrane fouling is the result of the combined action of pollutants in the membrane and sludge mixture. Various components of the ...
