| 摘 要： | 强化混凝去除有机物的效果与水源的分子量分布特性有着密切的关系.由于黄浦江水中低分子量的溶解性有机物占多数,因此,强化混凝处理有机物效果有限.对于＜1k分子量区间的有机物.增加混凝剂投量可有效去除紫外吸光值(UV254),但去除溶解性有机碳(DOC)的效果很差.尽管增加混凝剂投量和降低pH都能有效地去除有机物,但决定强化混凝效果的主要因素是pH,去除黄浦江水有机物的最佳pH范围为6～5.

| Abstract: | Effect on removal of organics by enhanced coagulation was closely related to the distribution of molecular weight (MW) in water source. Effect on removing organics from Huangpu River by enhanced coagulation was limited, due to the great majority of low MW of dissolved organics. For the organics in the presence of <1k MW region, effect on removal of organics by increasing dose of coagulant was good for UV354but poor for DOC. Although both increased dose of coagulant and reduced pH could remove organics effectively, the determining factor in removal efficiency was pH. The optimal pH for removing organics were ranged 6-5. |
