RESEARCH ON MEMBRANE BIOREACTOR TREATING DOMESTIC WASTEWATER AND RELATED MECHANISMS

摘要

Experiments on treatment of domestic wastewater by membrane bioreactors were carried out. The results showed that this process could produce good quality effluent with low COD, turbidity and Total count of bacteria. With intermittent operation and continuous aeration, the membrane flux was kept Steady. The mechanisms of removing COD through membrane, the structure of membrane and filtration Resistance were also discussed.
