将聚二甲基二烯丙基氯化铵(PDMDAAC)与聚合氯化铝铁(PAFC)复合制备了新型复合混凝剂PAFC-PDMDAAC (PAFC-PDM),对含藻的水库原水进行强化混凝处理研究.研究对比了PAFC-PDM,PAFC与预氯化工艺的除藻效果,并对其混凝除藻机理进行了初步探讨.结果表明,对于藻细胞数为7.98×106~1.17×107cells/L和浊度为2.56~3.59NTU的水库原水,当PAFC-PDM投加量为1.0mg/L时(以Al2O3计),藻类和浊度的去除率分别达到93.5%和81.7%,显著优于PAFC的混凝处理效果；对藻细胞进行扫描电镜和预氯化副产物分析表明,预氯化杀藻除藻方法,不仅破坏了藻细胞结构,而且产生了三卤甲烷类氯化消毒副产物,影响饮水水质；采用PAFC-PDM强化混凝工艺除藻,不破坏藻细胞,无消毒副产物.

The new coagulant PAFC-PDM composed of polydimethydiallylammonium chloride (PDMDAAC) and polyaluminum ferric chloride (PAFC) was used to investigate the effect of algae removal on the resource water. Experiments with prechlorination process to look into its effect on algae cell surface were also conducted. The results showed that the number of algal cells of 7.98× 106 ~ 1.17× 107cells/L and turbidity raw water reservoir for 2.56 ~ 3.59NTU, when PAFC-PDM dosing quantity is 1.0mg/L (Al2O3), algae and turbidity removal rate reached 93.5% and 81.7% respectively, significantly better than that of PAFC coagulation treatment effect; Scanning electron microscopy (sem) on the algal cells and pre chlorination by-products analysis showed that The latter not only destroyed the algal cell structure, but also produce trihalomethanes chlorination by-products, affected the water quality of drinking water. To remove the algae, the PAFC-PDM strengthening coagulation process does not destroy algal cells, and no disinfection by-products.
