摘　　要：海水淡化是核电厂获得生产用淡水的一个经济有效途径,某核电厂设计采用“混凝沉淀池+V型滤池+细砂过滤+一级反渗透+二级反渗透”工艺实现海水淡化。其中,混凝沉淀池上升流速1.80 mm/s;V型滤池滤速6.86 m/h;细砂过滤器滤速8.33 m/h;一级反渗透装置回收率45%,平均膜通量13 L(/m^(2)·s);二级反渗透装置回收率85%,平均膜通量27 L(/m^(2)·s)。工程设计运行电费1.72元/t,药剂费1.43元/t。海水淡化全厂布置采用三维正向设计,以检查和避免系统内设备、管道、桥架等的碰撞,可提高设计正确率、缩短设计周期。Seawater desalination is an economical and effective way for nuclear power plants to obtain fresh water for production.The seawater desalination system process in a nuclear power plant consists of coagulation sedimentation,V-type filter,fine sand filter,seawater reverse osmo-sis and brackish water reverse osmosis.The ascending velocity of coagulation sedimentation is 1.80 mm/s.The filtration rate of V-type filter is 6.86 m/h,while the filtration rate of fine sand filter is 8.33 m/h.The average membrane flux of seawater reverse osmosis system is 13 L/(m^(2)·s)with the recovery rate is 45%.The average membrane flux of brackish water reverse osmosis is 27 L/(m^(2)·s)with the recovery rate is 85%.The electricity charge for engineering design is 1.72 yuan/t,and the chemicals charge is 1.43 yuan/t.The three-dimensional forward design is used to check and avoid the collision of equipment,pipeline and bridge in the system,which improves the design accuracy and shorts the design cycle.
