摘要：

A combination of cell immobilization and membrane aeration approaches was used in a biological reactor to treat NH4+ in wastewater. Nitrifying microorganisms, immobilized by polyvinyl-alcohol (PVA) and attached to the surface of a silicone membrane tube, were used to develop a novel reactor for nitrification. The immobilized biofilm had a rubber-like elasticity and resisted shear stress over 5 months of operation. The reactor removed 95% of ammonium, added at 1.97 g N m(-2) d(-1), with O-2 enriching the membrane.
