摘　　要：采用NF90-4040膜组件对海水脱盐进行了实验研究,考察进水压力、温度、流量和进水含盐量对纳滤系统水收率、膜通量的影响。结果表明,随着进水压力的增大、温度的升高,膜通量均增大;而随着进水含盐量增大、进水流量的增大,水回收率降低。The study researched the applications of nanofiltration membrane module NF90-4040 in desalination, including the effects of water inflow pressure, temperature, flow and feed concentration on the water recovery rate and membranes flux of the nanofiltration system. The results showed that the water recovery and membranes permeations of the desalination system would increase withwater pressure and temperature rising. But the water recovery would decrease with the increase of feed flow and concentration.
