摘　　要：连云港市饮用水源蔷薇河近年来污染现象频发,文中对水源水进行分析测定,以确定不同时期(正常期与污染期)有机物分子量的分布特征:原水中的有机污染物主要为类酪氨酸和类腐植酸等,同时也包含芳香化合物和微生物代谢物。在水厂进行生产性试验,铁锰强化混凝可有效去除CODMn,在不同时期的去除率均达到10%以上,且其对浊度和色度的去除亦有很大效果。Pollution incidents in Qiangwei River, which is the drinking water sources of Lianyungang City, outbreak frequently recent years. The source water was analyzed to determine the characteristics of organic molecular weight distribution in different periods （ normal and pollution period ）. Results showed that organic contaminants in the water mainly were classes of trrosine and humie, while some aromatic compounds and microbial metabolites were also included. Production experiments were performed, indicating that enhanced coagulation by Fe and Mn could remove CODMn effectively The romoval of turbidity and color was also greatly improved.
