摘    要: 采用以粉末活性炭(PAC)作为填料的复合式膜生物反应器处理小区生活污水.该反应器在不人为排泥,不对膜进行任何处理(不空曝、不清洗)的情况下,连续运行100d.结果表明,系统运行稳定,出水水质优良(COD<25mg/L,NH4+-N<0.6mg/L,无色无味,无SS,没有检测出大肠杆菌).PAC不仅改善了膜生物反应器中的污泥混合液的沉淀性能与可过滤性,同时也改善了膜表面滤饼层的水力特性,从而达到了减小膜过滤阻力,延缓膜污染的目的,而且还降低了运行成本.

关 键 词:复合式膜生物反应器  粉末活性炭  污水处理

Abstract:The test studies of the domestic wastewater treatment in small area using hybrid membrane bioreactor with powdered activated carbon (PAC) as stuffing was introduced. This reactor had run continuously for 100d under the condition without artificial sludge discharge and any treatment of membrane (aeration, purification). The system operated stablely, with good effluent quality (COD<25mg/L, NH4+-N<0.6mg/L, without colour, smell and SS, and no coliform was detected). PAC improved not only the properties of the sludge mixed liquor in the reactor, but also the water power properties of cake layer on the surface of membrane; thus, the filtration resistance of membrane was reduced, the membrane pollution was lessened, and the operating cost was also decreased.
Keywords:hybrid membrane bioreactor  powdered activated carbon  wastewater treatment
