摘要：

采用滤布为基材形成动态膜生物反应器在低温条件下(9～13℃)处理校园生活污水。结果表明动态膜能在滤布表面很快形成且稳定存在。出水浊度小于9.5NTU，TSS多数运行时间为零，最大不超过5.0mg/L，COD和氨氮去除率分别为72%～89%和66%～94%。动态膜的过滤阻力比微滤/超滤膜要低2～3个数量级，泥饼层阻力是主要的污染阻力。

Abstract:

The performance of a dynamic membrane bioreactor by using the filter cloth as main material for domestic wastewater treatment at lowtemperatures (9～13 ℃) has been studied. The dynamic membrane could be formed on the surface of the filter cloth soon and develop steadily. When the permeate turbidity is less than 9.5 NTU. TSS is zeroat the most operation time, and its highest level is 5.0 mg/L, the CODand NH 3 -Nremoval rates are 72%~89% and 66%～94%, respectively. The total resistance of the dynamic membrane is lower than that of the microfiltration/ ultrafiltration membrane 2～3 numeral classes. Cake layer resistance is the major pollution resistance.

Key words: dynamic membrane, domestic wastewater, membrane bioreactor
