摘　　要：试验考察了粉末活性炭的投加对超滤膜运行性能的影响,结果表明:随粉末活性炭投量的增加膜稳定运行时间延长,通量下降率降低。粉末活性炭的投加对膜过滤阻力影响不大。在此基础上又对PAC-UF组合系统去除有机物的效果进行了进一步研究,主要是对比研究了不同PAC投加量对5种不同配置水样中有机物的去除效果。得出如下结论:在相同PAC投加量下,CODMn值大的水样的CODMn平均去除率高,且出水CODMn值相近。说明了PAC-UF组合系统出水稳定,受水质差异的影响不大。Effect of the powder active carbon （PAC） dosage on ultrafihrafion （UF） membrane performance was investigated. The results showed that stable operation time of UF membrane was lengthened and the lowering rate of the flux decreased when the PAC dosage was increased. An addition of PAC has no obvious effect on the membrane filtration resistance. Based on above the experiments, the removal efficiency of organic components in drinking water by combining uhraflhration and PAC （PAC-UF） was further studied, and eontrastively investigated effect of different PAC dosages on the removal efficiency of organic components in 5 drinking water samples with different ingredients. The larger the water sample CODa. was, the higher the average removal efficiency of CODMn; while the CODMn value of outlet water was nearly same. This result indicates that PAC-UF system has a stale effluent and is influenced little by the water quality difference.
