摘　　要：慢速脱碳是指在天然水中加入三氯化铁、石灰乳等药剂通过混凝和沉淀等方式来去除水中碳酸盐硬度的过程。在某发电厂应用实践表明,采用慢速脱碳工艺处理循环水补充水,可使水中的碱度和钙硬度大幅降低,因而可大幅提高循环水的浓缩倍率,达到节水目的。The slow speed decarbonization is a process in which the chemicals,such as FeCl3,and lime milk etc.,are put into water,and the carbonate hardness in water being reduced through coagulation and precipitation etc..The application practice in one power plant shows that the adoptation of said slow speed decarbonization technology in treatment of make-up water for the circulating water can make the alkalinity and calcium hardness in water to be greatly recuced,thereby the enrichment factor can be enhanced by a big margin,achieving the goal of water-saving.
