| 摘 要： | 采用混凝-砂滤-超滤膜的联用工艺对长江原水进行了中试研究，结果表明，混凝一砂滤作为预处理能有效地去除大分子的有机物．5个月的试验中，膜压差增长缓慢，实现了长期稳定运行．出水的浊度、CODMn和DOC的平均值分别为0．068NTU，1．23mg／L和1．3mg/L。

| Abstract: | A hybrid process of coagulation-sand filtration-ultrafiltration membrane for treatment of Yangtze River water was investigated in a pilot scale. The results demonstrated that coagulation-sand filtration as a pretreatment could remove organics effectively. The transmembrane pressure was increased slowly during running of 5 months, so that the long-term running had been achieved. The turbidity, COD_(Mn) and DOC in treated water were 0.068 NTU, 1.23 mg/L and 1.3 mg/L, respectively. |
