摘　　要：全氟化合物(PFCs)因具有强稳定性、疏水疏油性、高表面活性等而被广泛应用,其远距离迁移及高水溶性加剧了水体污染,如何高效低耗处理含氟废水已成为水处理领域亟待解决的难题。其中,电催化氧化技术因其高效清洁、易操作、自动化程度高等优势,被广泛应用于PFCs的处理。而基于穿流式的电催化膜电极发挥了滤膜、电极和催化三重作用,解决了传统电催化氧化系统中传质传荷受限、活性物种利用率低、高能耗等难题,对PFCs深度降解研究意义重大。基于此,主要介绍不同类型电极对PFCs的降解,着重针对穿流式电催化氧化系统进行介绍,包括技术发展历程、膜材料、反应器类型等,探讨其强化机制、PFCs的降解机理和电催化膜电极污染防控策略,并对该技术的未来发展趋势进行总结展望。Perfluorinated compounds(PFCs)are widely used because of their strong stability,hydrophobicity and oil repellency,high surface activity,etc.Their long-distance migration and high water solubility aggravate water pollution.How to treat fluoride containing wastewater with high efficiency and low consumption has become an urgent problem in the field of water treatment.Among them,electro catalytic oxidation technology is widely used in the treatment of PFCs because of its advantages of high efficiency,cleaning,easy operation and high degree of automation.The electrocatalytic membrane electrode based on the flow-through type plays a triple role of filter membrane,electrode and catalysis,which solves the problems such as limited mass and load transfer,low utilization rate of active species,and high energy consumption in the traditional electrocatalytic oxidation system,and is of great significance to the research on the deep degradation of PFCs.Based on this,this paper mainly introduces the degradation of PFCs by different types of electrodes,and focuses on the introduction of the through flow electro catalytic oxidation system,including the technological development history,membrane materials,reactor types,etc..Besides,the enhancement mechanism,the degradation mechanism of PFCs and the fouling prevention and control strategy of electrocatalytic membrane electrode were discussed,and the future development trend of this technology was summarized and prospected.
