摘　　要：北京市自来水集团有限责任公司第三水厂地表水处理工艺原用混凝剂为FeCl3,运行中出现了活性炭吸附池反冲洗水呈黑色及处理团城湖原水时砂池、炭池出水浊度偏高的问题。为此,第三水厂进行了大量工艺参数调整工作,但都没有彻底解决这些问题。利用混凝搅拌试验和过滤性能试验进行混凝剂比选,结合试验数据和问题原因分析,将地表水混凝剂由FeCl3更换为PAC。经过6个月的运行,以上两个问题得到较好解决。The surface water treatment process in Third Waterworks of Beijing Waterworks Group adopted FeC13 as coagulant. There were two problems in the operation： one was the black backwash water in activated carbon adsorption tank ; the other was the high outflow turbidity of V-filter and activated carbon adsorption tank. To this end, a lot of adjustments to the process parameters were carried out, but these problems were not completely solved. The coagulants were compared by coagulating mixing examination and filtering performance examination. FeC13 was replaced by PAC based on the analysis of experi- mental data. After 6 months of operation, the problems were solved.
