摘　　要：某滨海电厂制水采用反渗透海水淡化工艺,海水预处理系统采用加杀菌剂、凝聚剂和助凝剂处理,超滤反洗采用加酸、碱和杀菌剂进行加强反洗,反渗透系统进水采用加还原剂、阻垢剂处理,海水淡化产水水质调整采用加碱、杀菌剂、碳酸氢钠和氯化钙矿化剂处理。本文介绍电厂反渗透海水淡化加药系统的设计计算方法、详细配置情况和加药设备运行控制方式。Seawater reverse osmosis(SWRO)desalination system is adopted in a coastal power plant.The seawater pretreatment system is treated by bactericide,coagulant and flocculant dosing.The ultrafiltration(UF)backwashing is strengthened by acid,caustic and bactericide dosing.The SWRO system is treated by reductant and scale inhibitor dosing.The desalinated water is treated by caustic,bactericide,sodium bicarbonate and calcium chloride dosing.This paper introduces the design calculation,configuration and control mode of the SWRO chemical dosing system of the power plant,which will give a good reference and guiding significance for similar projects.
