· 58· 膜 科 学 与 技 术 第 32卷 concentration of sodium chloride in the feed solution;the rej ection of salt was hardly affected by these factors.The water permeate flux could reach 6.8 L/(m ·h)and the water G0R could reach 12.5 when the',concentration of sodium chloride in the feed solution was low;when the salt concentration was higher than 15 0.6,the water permeate flux was stil more than 5.2 L/(m ·h)and the water GOR was more than 6.2,the rejection of salt could reach 99.99 .Thus multi—efect membrane distilation process could efficiently deal with concentrated aqueous solution.
