| 摘 要： | 为探讨刘湾水厂滤池反冲洗水回用的可行性，用聚丙烯酰胺（PAM）作混凝剂，通过电动搅拌器进行混凝沉淀试验，试验结果表明应采用阳离子型PAM作混凝剂，其最佳投加量为1mg／L，静沉5min时上清液的浊度为1．48NTU，明显低于原水浊度。因此，该滤池反冲洗水可直接回用于原水中。

| Abstract: | In order to study the feasibility of recycling filter backwash water in Liuwan waterworks,this paper carried out the coagulating sedimentation test by means of motor stirrer with PAM(polyacrylamide) as the coagulant. The test results show that cationic PAM should be used as coagulant with the optimum dosage of 1 mg/L,and with 5 min sediment the turbidity of supernatant is 1. 48,obviously lower than that of raw water. Therefore,the filter backwash water could be directly recycled into raw water. |

| Keywords: | filter backwash water polyacrylamide turbidity optimum dosage sediment time |
