| 摘 要： | 强化混凝是去除水中消毒副产物的最佳方法之一。文章针对强化混凝技术,从去除水中有机物的角度出发,对不同聚合铝的处理效果进行了研究。结果表明,酸性条件、加大投药量有利于水中TOC及UV254的去除,且酸性条件更为有利。在pH=6.3,工业PAC投药量为1.5×10-4mo(l有效铝)时去除效果最佳,水中总有机碳(TOC)及紫外吸光度(UV25)4的去除率分别可达到46%及57%,实验室制备的聚合铝碱化度越高越有利于水中有机物的去除。

| Abstract: | Enhanced coagulation is one of the best methods to remove disinfection byproducts (DBPs) effectively. The effect on removal of organic substance from river water by different polymer aluminum chloride was investigated. Results showed that decrease of pH and increase of coagulant dosage can remove organic substance effectively, with acid conditions favorable for optimum removal rate. Under PAC dosage of 1.5×10-4mol and pH 6.3, the optimum removal efficiency of TOC and UV254 were 46% and 57% respectively. |
