MEMBRANE BIOREACTOR (MBR) AND STRUCTURE OF MOVING BED BIOREACTOR (MBBR) FOR WASTE WATER TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide a system for extending a washing interval of a membrane and reducing maintenance costs in a membrane separation activated sludge method.

SOLUTION: In membrane separation activated sludge treatment of the membrane bioreactor and a moving bed type bioreactor, a hydrodynamic separator is used as a pretreatment device of inflow water for reducing loads on membrane filtration and lowering energy costs by previously removing the most part of total suspended solids (TSS) in the inflow water, and then, treating it by a membrane separation activated sludge water treatment system.
