摘　　要：采用滤膜过滤法对杭州市钱塘江和苕溪两水源水四季的有机物分子质量(MW)分布进行了测定。结果表明,两水源水中有机物在不同分子质量区间的分布受季节变化的影响不是很显著;两水源水中的主体有机物为MW<1ku的小分子有机物,占总有机物的80%以上,其次为MW>10ku的有机物。与传统的混凝沉淀工艺相比,混凝沉淀与生物活性炭滤池组合工艺可明显提高对TOC和UV254的去除率,较适合用于杭州市水源水的处理。The molecular weight （MW） distributions of organic matters in Hangzhou Qiantanjiang and Tiaoxi source waters in four seasons were determined by membrane filtration method. The result shows no significant correlation is found between season and molecular weight distributions of organic mat- ters, the main organic matters in the source waters have MW less than 1 ku, being more than 80% of the total organic matters, and then are the organic matters with MW more than 10 ku. Compared with the tra- ditional coagulation sedimentation treatment process, the combined process of coagulation sedimentation and BAC filter can significantly improve the removal rates of TOC and UV254. The combined process is more suitable for treatment of Hangzhou source water.
