摘要
采用超滤膜法考察了东江水源水中有机物分子量分布特点,研究了东江泄洪和不泄洪水源水中有机物分子量分布的变化特征。结果表明,东江水源水在不泄洪期间水源水中的溶解性有机物主要为小分子量的有机物。而在泄洪期间,东江水源水中溶解性有机物主要为大分子量的有机物。UV254的分布和有机物分子量分布一致,DOC与UV254具有良好的相关性。泄洪期间水源水中SUVA值小于3,水体中有机物很难通过常规混凝工艺去除,此结果与水厂的实际运行情况相吻合。
This paper adopts ultra- filtration membrane method to investigate the characteristics of organic matter molecular weight distribution in East River water source and the characteristics of organic matter molecular weight distribution variation in East River water source with or without flood discharge are also discussed. The results show that organic matter molecular weights during the flood are mainly small in East River water source and molecular weight of the source water organic matters are mainly high. The value of SUVA is less than 3 during flood. It＇s very hard to purify organic matter through conventional coagulation process.
