| 以三氯化铝和有机高分子PGA为原料，制备了复合混凝剂CPAC，并探讨了该种混凝剂对含藻水的强化混凝去除作用.结果表明：复合混凝剂混凝效果优于单独的无机混凝剂PAC，当混凝剂投加量（以Al质量计）为4.5 mg/L时，PAC的浊度去除率为84.3%，而CPAC的浊度去除率达到93.1%；CPAC对高浊度原水的去除效果好于低浊度原水，当原水浓度从30 NTU提高到1 000 NTU时，混凝剂投加量为4.5 mg/L，其浊度去除率相应的由81%提高到98.2%；混凝剂最挂投加量约为4.5 mg/L，在此浓度下，浊度和叶绿素a 的去除率达到最高，分别为93.1%和82.5%；pH在5.0～9.0范围内，混凝效果均比较稳定. |

| Composite polymeric aluminum chloride (CPAC) was prepared by using polymeric aluminum chloride (PAC) and cationic polymer flocculant PGA.The enhanced coagulation with CPAC was carried out in micro- polluted reservoir water.The experiment results show that CPAC is better than PAC in treating wastewater.When Al dosage is 4.5 mg/L,the turbidity removal rate of PAC is 84.3% and 93.1% of CPAC;When the turbidity asscends from 30 to 1000,the removal rate ascends from 81% to 98.2% at the condition of 4.5 mg/L Al dosage.The optimum Al dosage is 4.5 mg/L according to the quality of raw water,and the removal rate of the turbidity and chlorophyll a is 93.1% and 82.5%.The optimum pH of CPAC ranges from 5.0 to 9.0,so it does not need to adjust the pH of the raw water in experiment. |
