摘　　要：选用纳滤膜NF270、DK、DL对浓海水进行实验研究。考察了不同操作压力下3种纳滤膜的透过通量、截留性能和分离系数的变化,从而选出适宜软化浓海水体系的纳滤膜。The experiments of the concentrated seawater were studied with the NF270, DK, DL nanofiltration membrane. The changes were investigated on through flux, intercept performance and separation factor of three nanofiltration membrane under the different operating pressure. It is in order to choose the suitable nanofiltration membrane of softening water system.
