摘　　要：采用1种新型的管式膜-生物流化床工艺进行生活污水处理试验。结果表明,当调节HRT为3 h、曝气体积流量为60 L/h时,系统能长时间稳定运行,对COD、NH4+-N和TN的去除率分别达到95%、94.2%和84.6%,具有较好的降解有机物及脱氮能力。膜的截留对有机物和氮的去除起到一定的强化作用。A new type of tubular membrane-biological fluidized bed process was used to treat the domestic sewage. The results showed that the system can run stably for a long time under the condition of HRT of 3 h and aeration quantity of 60 L/h, and it had better removal effect in COD, NH4＋-N and TN, with the average removal rate of 95%, 94.2% and 84.6%, respectively. In addition, the membrane rejection enhanced the pollutants removal efficiency.
