[0002] Membrane bioreactor (MBR) is a new type of high-efficiency sewage treatment technology that combines membrane separation technology and biological treatment technology. It can effectively separate mud and water. Compared with traditional sewage treatment processes, it has membrane components that replace the terminal secondary sedimentation tank of traditional biological treatment technology, maintain a high concentration of activated sludge in the MBR, and increase the organic load of biological treatment, thereby reducing the biochemical hydraulic retention time and the floor area of ​​sewage treatment facilities, and reducing the amount of residual sludge by maintaining a low sludge load; secondly, the effective interception effect of MBR can retain microorganisms with a long generation cycle, which can achieve deep purification of sewage. At the same time, nitrifying bacteria can fully reproduce in the system, and its nitrification effect is obvious, which provides the possibility for deep phosphorus removal and nitrogen removal.
