Effectiveness of application of negative DC electrical potential to electro-conductive MF/UF membranes with cross flow filter was investigated to remove aqueous materials and solids having negative electric potential in raw water of water supply. A solution of humic acids with TOC 3 mg/L was used as model feed solution on MF membrane filter and falvic acids extracted from leaf mold with 5 mg/l was used on UF.The removal efficiency of TOC and E260 in MF and UF membrane filters increased as applied electric potential increased. The removal efficiency of TOC on MF was 76% at 75mA and on UF reached nearly 100% at 30mA.And the removal efficiency of E260 on MF was 80% at 75mA.The filtration flux of MF membrane did not change with electric potential increased and kept 4m/day, but flux of UF membrane decreased with electric potential increased by miropore blockade by bubble of electrolysis and reached nearly zero m/day at 30mA.

研究了直流负电位对导电MF/UF膜错流过滤器去除供水原水中具有负电位的含水物质和固体的效果。以TOC为3 mg/L的腐殖酸溶液为MF膜过滤器的模型料液，以5 mg/L的叶霉病菌中提取的镰孢酸为UF膜过滤器的模型料液，MF和UF膜过滤器对TOC和E260的去除率随外加电位的增大而增大。超滤膜在30 mA时对TOC的去除率接近100%;超滤膜在75 mA时对TOC的去除率接近80%;超滤膜的过滤通量不随电位的增加而变化，保持在4 m/d，而超滤膜的通量随着电位的增加而减小，在30 mA时，膜通量接近于零m/d。
