摘　　要：采用粉末活性炭-超滤膜工艺对微污染原水进行处理.试验主要研究该工艺对有机物的去除效果,粉末炭改善膜通量以及防止膜污染的效果.投加粉末活性炭能有效地提高膜通量,通过反冲洗,膜通量能得到很好的恢复,说明粉末炭能防止膜污染.由于粉末炭去除小分子量的有机物效果良好,因此,该工艺能有效地去除有机物和消毒副产物.The powdered activated carbon(PAC)-ultrafiltration membrane process was used to treat micro-polluted water resources,in terms of the efficiency of organics removal,enhancing flux and effect of preventing membrane from fouling.It was found that PAC addition was effective in enhancing flux and that flux could be recovered by backwash,suggesting that PAC can prevent membrane from fouling.The process could remove organics and disinfections by-productions(DBPs)due to effective removal of lower molecular weight(MW)by PAC.
