摘要
膜是膜技术的核心。在对废水进行膜分离过程中,对膜材料的性能往往存在着几个截然不同的要求,既要求有高的水通量,又要求有高的选择性,且具备良好的抗污染性能。因此开发具有某些需要的性能的膜分离材料是解决水污染治理中膜分离技术应用问题的关键。本文综述了当前国内外膜分离材料改性研究的主要方法和研究进展,提出通过共混合金的方法对膜材料进行改性是提高膜材料分离性能的捷径。
Membrane materials play a vital role in membrane science. In all separation process of wastewater treatment, membrane materials are required with higher water flux and solute rejection, and better hydrophilicity. Thus, developing some membrane materials with special characteristic function is the key to application of separation membrane technology in wastewater treatinentl In this paper, the ways of modification on polymer membrane materials were introduced, and a conclusion was made that to make two or more materials alloys was an effective and easy way to modify material properties and expanded the use of membranes.
