| 摘 要： | 用聚合硫酸铁(PFS)和聚二甲基二烯丙基氯化铵(PDM)制备了复合混凝剂—聚合硫酸铁-聚二甲基二烯丙基氯化铵(PFS-PDM),并对微污染的流溪河水源水进行了强化混凝处理,对比分析了复合混凝剂与PFS2种处理的混凝效果.结果表明,与单独用PFS相比,用复合混凝剂处理冬季微污染流溪河水源水时,其对浊度、UV254及藻类去除能力更强;当投加量为3mg/L(以Fe计)时,PFS-PDM复合混凝剂的去浊率、除藻率和UV254去除率,分别提高22.1%、19.5%、14.9%,表现出优良的强化混凝效果.

| Abstract: | The composite coagulant of PFS-PDM —was prepared by polyferric sulfate and poly (dimethyldiallylammonium chloride). The enhanced coagulation treatment of micro-pollution Liuxi River water was studied with the composite coagulant of PFS-PDM. The treatment efficiency of the Liuxi River water with PFS and PFS-PDM were compared and analyzed. The experimental results showed that the removal efficiency of turbidity, UV254, and algae from micro-polluted source water by the composite coagulant was higher than PFS. The removal efficiency of turbidity, algae and UV254 increased by 22.1%、19.5% and 14.9% respectively when PFS-PDM dosage was 3mg/L. The composite coagulant showed better enhanced coagulation performance. |
