Problems solved by technology

[0002] At present, the MBR membrane biochemical system has been widely used. However, during the operation of the MBR membrane biochemical system, due to equipment maintenance, membrane cleaning, membrane replacement and other reasons, it is inevitable that there will be a long period of shutdown, which often leads to front-end Situations where the backlog of sewage cannot be treated

Abstract

The invention relates to a quasi-precipitation type MBR membrane biochemical system and an operation method thereof, the quasi-precipitation type MBR membrane biochemical system comprises a biochemical pool, a quasi-precipitation type MBR membrane pool and a water collection and discharge area, the biochemical pool is provided with a water inlet, a biological filler, an aeration system and an overflow pipeline, the quasi-precipitation type MBR membrane pool comprises a precipitation area, a clear water area and a water collection tank; the water collection tank is provided with a discharging port communicating with the water collection and discharge area; the quasi-precipitation type MBR membrane pool further comprises an MBR membrane stack arranged in the clear water area, a water producing pipe which is arranged on the MBR membrane stack and leads to the water collection and discharge area, and an aeration pipe which is arranged on the MBR membrane stack and is communicated with an aeration system. The system has the advantage that when the MBR membrane stack cannot produce water normally, the sedimentation tank can be used for producing water through the water collecting tank.

Description

technical field [0001] The invention relates to a quasi-precipitation type MBR membrane biochemical system and an operation method thereof, belonging to the field of environmental protection water treatment. Background technique [0002] At present, the MBR membrane biochemical system has been widely used. However, during the operation of the MBR membrane biochemical system, due to equipment maintenance, membrane cleaning, membrane replacement and other reasons, it is inevitable that there will be a long period of shutdown, which often leads to front-end The backlog of sewage cannot be treated. Contents of the invention [0003] The purpose of the present invention is to provide a quasi-precipitation MBR membrane biochemical system, which can continue to produce water when the MBR membrane system cannot operate. [0004] The purpose of the present invention is achieved like this: [0005] 1. A quasi-sedimentation MBR membrane biochemical system, comprising a biochemical...
