摘　　要：本研究采用混凝和超滤膜联用的处理工艺对淮河水进行了中试试验。试验结果表明，膜处理的浊度和COD_(Mn)均优于同期的自来水，对处理过程进行的有机物分子量分布的测定分析表明，膜能去除小分子量的非UV_(254)类的有机物。试验期间，膜压差没有上升，表明所采用的预处理是成功的。A combination of ultrafiltration (UF)membrane with coagulation was tested for treatment of Huaihe River water with pilot-scale. The results demonstrated that turbidity and COD_(Mn) in membrane-treated water was lower than those by traditional treatment in the same time. By mean of determining distribution of organic molecular weight, it was showed that the non-UV254 organics with less than 1k MW can be removed by membrane. During the time of experiment, the transmembrane pressure was not increased, showing that the pretreatment used in this study was successful.
