摘要:

根据纳滤膜分离不同性质的物料,评述了纳滤膜分离机理研究进展。纳滤膜分离非电解质时描述模型有立体阻碍-细孔模型;分离电解质和离子时包括空间电荷模型、固定电荷模型、静电阻碍模型和道南-细孔模型。综述了纳滤膜应用于染料废水处理的现状。

Abstract:

The separation mechanism of nanofiltration, its application in dye wastewater treatment are reviewed. The three-dimensional hindrance pored model can be applied to characterize the nonelectrolyte separation. The space charge model, the fixed-charge model, the electrostatic and three-dimensional hindrance model, Donnan-steric pore model can be applied to characterize electrolyte and ion separation. Recent development of the dye wastewater treatment with nanofiltration membrance are introduced.

Key words: nanofiltration membrance, separation mechanism, dye wastewater
