摘要:

聚酰胺反渗透膜具有选择透过性高、化学稳定性好等优点,在水处理领域应用广泛。但膜污染导致的通量下降、寿命降低等问题严重制约了其发展与应用,开发抗污染反渗透膜是缓解膜污染的重要手段。本文根据抗污染膜作用机理将抗污染反渗透膜分为抗黏附型、污染驱除型和杀菌型,综述了近年来相关方面的研究成果,并对合理组合多种机制制备抗污染反渗透膜的进展进行简要概括,最后对抗污染反渗透膜的发展前景进行了展望。

Abstract:

Polyamide reverse osmosis membrane has the aduantages of high seleetive permeability and good chemical stability, and is widely used in the field of water treatment. However, the problems caused by membrane fouling, such as decreased flux and reduced membrane life, have severely restricted its development and application. The development of antifouling reverse osmosis membrane is an important solution to alleviate membrane fouling. In this review, the mechanisms of antifouling reverse osmosis membrane are divided into fouling resistance, fouling release and antibacterial. The progress in inhibiting the membrane fouling by using single antifouling mechanism and integrating multi-mechanisms is introduced briefly. Finally, the prospects of antifouling reverse osmosis membranes are proposed.

Key words: reverse osmosis, membrane, fouling resistance, fouling release, antibacterial, surface, polymers
