China Environmental Science, 2003,23(2)：196~200 Abstract：The application of membrane bioreactor (MBR) in treating the water of micro-polluted water source has received much concerns recently in the domain of water environment. In this paper, the operation character of suspended growth type of MBR and three adhesive growth types of MBR in treating the water of artificially simulated micro-polluted water source was investigated. Experiment results showed that these 4 MBRs had ammonia nitrogen removal rate over 85%~90% . MBRs filled with nubby filler or powdered
