高级氧化法处理氯酚类污染物的研究进展

Research Progress of Advanced Oxidation Process on the Treatment of Chlorophenol Pollutants

氯酚类污染物(CPs)具有污染范围广、生物难降解等特点。传统的处理方法(生物、物理、化学)存在处理效率低、有二次污染等缺点。高级氧化技术因其具有氧化性强、无二次污染等特点,能够高效处理CPs而得到广泛关注。文章综述了湿式氧化技术、臭氧氧化技术、电催化氧化技术、光催化氧化技术、Fenton/类Fenton氧化技术等,并对以上技术的优缺点进行了阐述,结合近年来高级氧化技术在氯酚类污染物处理中的应用进展,对它们的原理进行了分析。最后对高级氧化技术处理氯酚类污染物的未来前景做出展望。

Chlorophenolic pollutants(CPs)have a wide range of pollution and are difficult to biodegrade.The traditional methods,such as biological,physical and chemistry methods,have low degradation efficiency for CPs,and may cause secondary pollution.The advantages of advanced oxidation processes(AOPs)are no secondary pollution,and high removal efficiency for the treatment of CPs,which were attracted widely attention.This paper briefly introduced all kinds of AOPs,such as wet oxidation,ozone oxidation,electrocatalytic oxidation,photocatalytic oxidation,and Fenton/Fenton-like oxidation technology.The advantages and disadvantages of the above technologies were explained,combined with the application progress of AOPs on the treatment of CPs in recent years,the reaction principles were analyzed.Finally,the development of AOPs to treat chlorophenol pollutants is prospected.
