DEVICE AND METHOD OF SLUDGE REDUCTION AND WASTEWATER REUSE SYSTEM USING MEMBRANE BIO REACTOR

摘要

An apparatus for reusing wastewater and decreasing sludge using an MBR(Membrane Bio Reactor) is provided to remove effectively nutritive salts including nitrogen and phosphorus included in inflow water and remained sludge discharged from the MBR according to a concentration of the phosphorus in the inflow water and to re-use sewage treating water using a Nano-Filtration membrane. An apparatus for reusing wastewater and decreasing sludge using an MBR(Membrane Bio Reactor) contains a membrane separating an activated sludge unit, an MBR tub for decreasing sludge and a treated water regenerating unit. The membrane separation activated sludge unit removes materially nutritive salts such as nitrogen and phosphorus included in inflow water using an anaerobic anoxic deformation tub and an MBR(Membrane Bio Reactor) tub.
