摘　　要：在不增加任何构筑物和设备的前提下,利用水厂工艺特点,在同一水厂,使用硫酸铝(AS)、聚合氯化铝(PAC)、聚合硫酸铁(PFS)3种混凝剂,通过混凝搅拌试验结合实际应用,总结出这3种混凝剂的优缺点及最佳投量范围和使用时间。针对不同季节,不同原水水质,选择使用不同的混凝剂,成功应对了原水水质变化,达到了优质、低耗的供水目标。Under the premise of not adding any structure and equipment, based on the technological characteristics of a waterworks, three kinds of coagulants of aluminum sulfate （AS）, polyaluminium chloride （PAC） and polymeric ferric sulfate （PFS） were adopted at the same waterworks. The advantages, disadvantages, optimal dosing range and usage time of the three coagulants were summarized by coagulation mixing experiment combined with the practical application. According to different seasons and different raw water quality, different coagulants were used, and the change in the raw water quality was successfully dealt with, thus achieving the target of water supply with high quality and low consumption.
