摘要
天然有机物(NOM)存在于地表水、地下水和土壤水中。超滤(UF)膜技术具有运行压力小、设备集成化程度高和占地面积小等优势,但NOM造成的复合污染使超滤膜在水处理的应用管理变得复杂。本文在概述NOM的来源、组成和化学性质的基础上,通过分析不同结构特征的NOM间的相互作用机制,阐述了不同结构特征的NOM的复合膜污染。从离子与NOM络合的影响因素、络合对NOM理化性质的影响等,分析了离子与NOM的复合膜污染。最后,分析了目前研究面临的挑战,并对未来的发展方向进行了展望。
Natural organic matter(NOM)is found in surface water,groundwater and soil water.Ultrafiltration(UF)membrane technology has the advantages of low operating pressure,high degree of equipment integration and small footprint,but the composite pollution caused by NOM makes the application management of UF membrane in water treatment complicated.Based on an overview of the source,composition and chemical properties of NOM,this paper describes the composite membrane fouling of different structural characteristics of NOM by analyzing the interaction mechanism between different structural characteristics of NOM molecules.From the factors affecting the complexation of ion and NOM and the effects of complexation on the physicochemical properties of NOM,the composite membrane fouling of ion and NOM was analyzed.In order to provide theoretical support for the optimization of ultrafiltration membrane processing technology.
