Technical Field

[0001] The utility model relates to the technical field of membrane bioreactors, in particular to reclaimed water equipment with a biofilm reactor as the main body. Background Art

[0002] Membrane bioreactor (commonly known as MBR) is a new type of efficient sewage treatment process that organically combines membrane separation technology with traditional sewage biological treatment processes. The membrane separation process replaces the secondary sedimentation tank in the traditional activated sludge method to achieve mud and water separation. The microbial flocs and relatively large molecular weight organic matter in the activated sludge mixed liquor intercepted by the membrane flow back into the bioreactor, so that a high concentration of biomass is obtained in the bioreactor, the average residence time of microorganisms is extended, and the oxidation rate of microorganisms to organic matter is increased. Compared with traditional biological treatment processes, MBR has the advantages of high biochemical efficiency, high organic load, low sludge load, good effluent quality, small equipment footprint, and easy automatic control and management.
