摘要
本研究采用双级纳滤技术对苦咸水进行脱盐淡化,探究一级纳滤和二级纳滤不同的压力条件,对纳滤膜通量、钙离子、硫酸根离子、氯离子、总硬度的影响。研究得出,一级纳滤工作压力保持在1.0-1.1MPa,二级纳滤工作压力保持在0.6-0.8MPa,可取得理想的淡化效果。
Dual-stage nanofiltration for brackish water desalination was adopted in this study, and the influence of different pressures on nanofiltration membrane flux, calcium, sulfate, chloride ion, total hardness were researched. Experimental results showed that nanofihration membrane for desalination can achieved ideal effect when the first-stage pressure was kept between 1.0-1.1MPa and the second-stage was 0.6-0.SMPa.
