| 摘 要： | 以不同碱化度(B)的聚合氯化铝(PAC)和二甲基二烯丙基氯化铵均聚物(PDMDAAC)制备聚合氯化铝-二甲基二烯丙基氯化铵均聚物复合混凝剂(PAC-PDMDAAC)，试验了其处理模拟水的除浊效果及水体的残余铝量。结果表明：PAG-PDMDAAC较PAC具有更低的投加量，更好的除浊效果，处理后水体具有更低的残余铝量。B和PDMDAAC质量百分含量(P％)对PAC-PDMDAAC除浊效果及水体的残余铝量有不同程度的影响。

| Abstract: | Composite flocculants of polyaluminum(PAC)-ploydimethyldiallylammonium chloride(PDMDAAC)was prepared by using PAC with different basicity(B)and PDMDAAC as raw materials.And the flocculating efficiency of PAC-PDMDAAC treating simulating water was preliminary examined by Jar-test.The experimental results show that the PAC-PDMDAAC is characterized by lower dosage and better coagulation efficiency and lower residual aluminum in treated water compared with PAC.The B value of PAC,the content(P%)of PDMDAAC and pH value effect on the coagulation efficiency and the residual aluminum. |

| Keywords: | composite flocculant removing turbidity residual aluminum. |
