摘　　要：通过在越南某电厂运行水源受海水倒灌影响的工程设计中,提出锅炉补给水处理系统采用反渗透装置作为预脱盐处理手段,并在设计中设置反渗透段间增压泵。在海水倒灌期间启用段间增压泵,可以提高反渗透第二段膜堆的产水量,从而提高反渗透系统膜的利用效率,降低系统能耗。Through the engineering design of boiler make-up water source affected by sea water invasion of a certain power plant in Vietnam, the reverse osmosis device was put forward as pre-desalination treatment method in boiler make-up treatment system and the inter-section booster was set between the two sections of RO system. When the water source was affected by salty tide, the inter-section booster should be started up. Thus the output of the second membrane stack can be raised greatly. Consequently the utility efficiency of RO membranes can be increased and the system＇s energy consump- tion can be lower.
