摘要
选择了NE和HL两种纳滤膜对NaCl、KCl、Na2SO4、MgCl2、CaCl2及MgSO4等6种无机盐水溶液体系进行分离实验;考察纳滤膜分离性能随操作压力、料液浓度、无机盐种类等变化的影响及纳滤膜脱盐的稳定性,得到纳滤膜一些脱盐的规律。
Desalination experiments of six inorganic salt solutions (NaCl?KCl?Na2SO4?MgCl2?CaCl2 and MgSO4) were carried out by using two kinds of nanofiltration membranes (NE and HL membranes).The effects of the species and the concentration of salts as well as the operation pressure on the separation performance and the stability of nanofiltration membranes were investigated,and some rules of salt removal with nanofiltration membranes were gained.
