摘要 本文采用超滤膜法,使用美国 Amicon 超滤膜对钱塘江流域杭州地区两种水源水进行了有机物分子量分布的测定。结果表明,钱塘江水源水和贴沙河水源水中总有机碳的主体有机物的分子量都在3000以下,分子量小于3000的溶解性有机物占地表水总有机碳的80%左右,传统工艺对这类有机物的去除效率较低。混凝沉淀和生物活性碳滤池相结合的工艺是钱塘江水源水处理工艺的首选。 source water;ultrafihration;molecular weight distributions of organic matters Organic matter has been measured in Qiantanjiang valley Hangzhou area source water by ultrafihration.The result shows the main organic matter in Qiantanjiang and tiesahe source water is MW<3000,the content of organic matter of MW<3000 is about 80 percent.Therefore traditional treatment process can not remove the organic effectively,traditional treatment process combined with GAC filter is the preferred process.
