摘　　要：根据电厂循环水排污水低碱度高硬度的水质特点,采用聚合硫酸铁作为混凝剂,聚丙烯酰胺作为助凝剂,CaO、Na2CO3、NaOH分别作为软化剂,对电厂循环水进行混凝实验,结果表明,NaOH处理比CaO处理、Na2CO3处理、CaO+Na2CO3处理具有明显的优势。According to the power plant circulating waste water of low alkalinity and high hardness water quality characteristics, using of PFS as a coagulant, polyacrylamide as coagulant aid, lime, sodium hydroxide and sodium carbonate were used as the softener in coagulation tests. The results showe that from the treatment effect, operating costs and investment costs, for such a low alkalinity high hardness circulating waste water, sodium hydroxide had more advantages than lime, sodium carbonate, and lime ＋ sodium carbonate.
