摘　　要：介绍了10万m^3/d规模青岛某膜法海水淡化厂的设计。其工艺采用了自动清洗微孔过滤+超滤膜预处理系统,两级反渗透除硼系统,能量回收系统,二氧化碳+饱和石灰水后处理系统,浓盐水排海系统等,产水与自来水1∶5混合后进入市政给水管网。The process design of a membrane seawater desalination plant （capacity 100 000 m3/d） in Qingdao was investigated in this paper. The pre treatment system of self cleaning microporous filters and ultra filtration, two slage reverse osmosis system to remove boron, energy recover systern, post treatment system of carbon dioxide and lime dosing and brine discharge system werecombined for seawaterr desalination. The desalted water and water treatment plant output watcr 1 ： 5mixed into the urban water supply network.
