Abstract

Abstract:

Dynamic membrane bioreactor(DMBR)is regarded as a kind of the most promising and widely used wastewater treatment technology. Compared with traditional membrane bioreactor(MBR),DMBR has similar treat-ment effect,possessing higher membrane flux,and its membrane fouling can be controlled more easily. The courses of formation and regeneration of both self-forming dynamic membrane and precoated dynamic membrane are analyzed briefly. Furthermore,the research progress in the influential factors,such as membrane materials,activated sludge properties,operating conditions,etc.,on membrane fouling are summarized. The existing problems and future prospects in the research and application of DMBR process are pointed out.

Key words: dynamic membrane bioreactor, membrane fouling, trans-membran epressure difference, activated sludge
