The invention discloses a sewage treatment device using a jet aeration integrated membrane bioreactor. The device comprises a peristaltic pump, a flow meter, a flat sheet membrane, a jet aerator, a support frame, a common aerator and a micro peristaltic pump, wherein the flat sheet membrane penetrates through an opening through a hose to be connected with an inlet of the peristaltic pump, an outlet of the peristaltic pump is communicated with the flow meter through a hose, and the other end of the flow meter is connected into a water tank at the upper end through a hose; the jet aerator is arranged on the support frame, the micro peristaltic pump is arranged above the common aerator, a hose is connected through a tee joint and communicated with the common aerator and the micro peristalticpump, and the hose on the micro peristaltic pump penetrates through an overflow hole. The device can effectively increase the membrane surface cross flow speed through jet aeration according to causesand control countermeasures of membrane pollution, so that membrane pollution is greatly retarded.
Description
technical field [0001] The present application relates to a sewage treatment device, in particular to a sewage treatment device using an integrated membrane bioreactor with jet aeration. Background technique [0002] At present, most of the membrane sewage treatment devices are composed of separation tanks, flow meters, water pumps, aerators, hoses, power supplies and PVDF flat templates connected in series, not integrated. When treating sewage, the pretreatment needs to be treated separately, and after treatment, it needs to be placed in a PVDF flat membrane device, which is inefficient and wastes resources; Under normal circumstances, the oxidation of sewage decomposes the organic pollutants in the wastewater, but it will cause greater membrane fouling. Contents of the invention [0003] In view of the above problems, the technical problem to be solved in this application is a sewage treatment device using an integrated membrane bioreactor with jet aeration. The purpose...
