摘　　要：膜分离技术是一种无相变、低能耗、高效率的水处理技术,在海水淡化、饮用水处理、污水深度处理和工业分离等领域已有广泛的应用。电化学阻抗谱(EIS)技术具有原位、快速、无损、可重复性高等优点,通过对反馈信号进行电路拟合可探究离子在膜表面及膜孔内部的分布状态和迁移行为,是深入研究水处理分离膜构效关系及运行状态的一种有力方法。本文简述了EIS技术应用于水处理分离膜研究中的基本原理,在此基础上综述了EIS技术在膜结构、膜性能及膜过程中产生的浓差极化、膜污染等问题研究中的应用进展。最后进行总结并对其发展作出了展望,以期为采用EIS技术对水处理分离膜进行更深入的研究提供参考。Membrane separation technology is a phase-change-free,low-energy,high-efficiency water treatment technology,which has been widely used in the fields of seawater desalination,drinking water treatment,deep treatment of sewage and industrial separation.Electrochemical impedance spectroscopy(EIS)has the advantages of in-situ,fast,non-destructive and reproducible,etc.By fitting the feedback signal to the equivalent circuit,it can investigate the distribution state and migration behavior of ions on the membrane surface and inside the membrane pores,and it is a powerful method for in-depth study of the constitutive relationship and operational status of water treatment separation membranes.This paper briefly describes the basic principles of EIS technology applied to the study of water treatment separation membranes,on this basis,the progress of the application of EIS technology in the study of membrane structure,membrane performance and the problems of concentration polarization and membrane contamination generated in the membrane process is reviewed.Finally,it is summarized and the outlook of its development is made,with a view to providing a reference for more in-depth research on water treatment separation membranes using EIS technology.
