摘　　要：采用膜-序批式生物反应器处理生活污水,在不排泥条件下考察了系统连续运行的稳定性。结果表明在气水比为35∶1、运行周期为5.75h时,系统出水稳定,COD_(Cr)、氨氮和浊度平均去除率分别为89.8%、99.3%、99.6%;膜自身的平均去除率分别为10.2%、0.1%、9.5%。膜分离过程强化了系统处理效果;膜操作压力(TMP)上升缓慢,出水水质优于生活杂用水水质标准。Membrane-sequencing bioreactor was used to treat residential sewage.The stability of system was investigated without sludge discharge.The result shows that the average removal efficiency of COD_(Cr) ,ammonia nitrogen and turbidity has reached 89.8%,99.3% and 99.6% respectively under the conditions of air-water ratio 35∶1,operation period 5.75 h.The membrane has a contribution to the removal efficiency of COD_(Cr) ,ammonia nitrogen and turbidity respectively with 10.2%,0.1% and 9.5%.The membrane separation process can enhance the waste water treatment effect and trans-membrane pressure(TMP) rises slowly.The effluent quality was superior to the standards for water reuse.
