摘　　要：对比了单独膜与膜生物反应器(MBR)对微污染原水的处理效果,并研究了投加氯化铵、葡萄糖和粉末活性炭等强化措施对MBR处理效果的影响。结果表明,单独膜工艺对CODMn和氨氮去除率只有16%和5%;而以粉末活性炭为生物载体的MBR工艺对CODMn和氨氮去除率提高到35.3%和44.5%;提高原水有机物浓度和氨氮浓度对CODMn和氨氮去除效率提高作用有限;更换10%的PAC后,提高了MBR对CODMn的去除效果,其去除效率可由原来的35.3%提高到50%。Comparison of treatment effect is investigated using individual membrane and membrane bioreactor（MBR） for micro polluted water.Hybrid of enhancement technique and MBR is also studied through ammonia chloride,glucose and powdered activated carbon（PAC） added.The results illustrate that the chemical oxygen demand（CODMn） and ammonia-N removal efficiency of individual membrane is 16% and 5% respectively.But the CODMn and ammonia-N removal efficiency of MBR reaches 35.3% and 44.5% respectively.Hybrid of microbial enhancement technique and MBR cannot obtain high removal efficiency for CODMn and ammonia-N by increasing the organic carbon and ammonia-N levels of raw water.10% PAC renewed raises the CODMn removal efficiency from 35.3% to 50%.
