摘　　要：将热电厂循环冷却排污水进行旁流过滤脱盐处理,既可以提高循环冷却水的浓缩倍数,改善循环冷却水的运行工况,又可以减少排污水量和新鲜补水用量,提高电厂水利用率。该处理工艺由两级过滤、反渗透脱盐、加药等部分组成,处理后再生水达到循环冷却水补水的水质标准。The circulated cooling water from a thermal power plant was treated by means of filtration and desalination,which could increase the concentration multiples of the circulated cooling water,also could reduce sewage water and fresh water supplement dosage,increasing water use rate in the power plants.The treatment process was comprised of the two filters,reverse osmosis desalination,and addition of chemical agents.After the processing,the reclaimed water could be used as supply water to the circulating cooling water.

关 键 词：循环冷却排污水 脱盐 连续动态过滤器 反渗透
