| 摘 要： | 以温州市内桌一富营养化水体为研究对象，考察本地粘土矿物高岭土联合聚合氯化铝（PAC）混凝沉降工艺的除藻效能，并获得处理工艺的最佳条件，为恢复河流水体生态自净功能提供理论基础。试验结果表明，PAC最佳投加量为40mg／L；高岭土的最优投加方式为在混凝剂PAC前5rain投加；其最佳投加量为3g／L；最佳搅拌方式为200rpm搅拌4min；最佳静置时间为20min；在酸性或中性水体的处理效果尤佳。

| Abstract: | This paper studied the effect of Kaolin as coagulation on freshwater algae removal in eutrophic waters in Wenzhou through PAC flocculation. The optimum condition for static treatment is determined by single factor process, which can provide the fundamental basis for recovering the water self - purification capacity of rivers. The optimum results can be described as ：PAC dos- age 40 mg/L, adding 3 g/L Kaolin as coagulation 5 min earlier than adding PAC. The stirring intensity was 200 rpm for 4 min, the settling time was 20 min and the water pH value was acidic or neutral. |
