介绍了沙特延布水泥厂海水淡水系统的设计方法及工艺流程,设计出2级多介质过滤器加2级反渗透的海水淡化工艺系统,叙述了海水预处理系统、一级反渗透系统、二级反渗透系统、产水输送系统、加药系统、辅助系统等6大子系统的相关设备和重要参数。调试运行结果表明,该系统产水水量达到125 m3/h,水质符合世界卫生组织控制要求,产水合格,解决了水泥厂用水短缺问题。
The design method and technological process of seawater freshwater system in Yanbian cement plant in Saudi Arabia were introduced. A desalination process system of 2 - stage multi - media filter plus 2 - stage reverse osmosis was designed. The seawater pretreatment system, primary reverse osmosis system, Level reverse osmosis system, water delivery system, dosing system, ancillary systems and other six major subsystems related equipment and important parameters. The results of commissioning showed that the water volume of the system reached 125 m3 / h, the water quality conformed to the control requirements of the World Health Organization, and the qualified water was produced, thus solving the problem of water shortage in cement plants.
