摘　　要：将二级城市污水用作火电厂循环水补充水时,水中的微生物、氨氮、有机物等会对循环水系统的运行产生一定影响,尤其在系统高浓缩倍率运行时,这种影响将更为严重。对此,开发了合理、经济的循环水缓蚀与阻垢技术,解决了因此产生的问题。In case of reusing secondary urban sewage as make-up water for circulatory cooling water in thermal power plant, microorganism, ammoniacal nitrogen, and organics etc. in water may produce certain effects upon the operation of circulatory cooling water system, especially at the time of high enrichment rate operation of the said system, the above-mentioned effects will be more serious. For this reason, a reasonable and economic corrosion-and scale-retardation technique has been developed, having solved problems resulted from above-listed causes.
