基于过氧乙酸处理水中新污染物的研究进展

Research Progress on the Treatment of New Pollutants in Water Based on Peracetic Acid

为了解决新污染物(emerging contaminants,ECs)在地表水和饮用水中威胁人类健康的问题,探讨了过氧乙酸(PAA)处理水中有机污染物的高级氧化技术(AOPs)。活化PAA有多种方式,包括光催化(紫外线UV)、超声活化(US)、过渡金属离子(Fe、Co、Mn和Cu)活化等。综述了基于PAA的AOPs去除水中有机污染物的相关研究成果,探讨了联用技术存在的问题与发展前景,为开发活化PAA技术处理水中新污染物提供了参考。

In order to solve the problem of emerging contaminants(ECs)threatening human health in surface water and drinking water,the advanced oxidation technologies(AOPs)of peroxyacetic acid(PAA)for the treatment of organic pollutants in water are discussed.Activating PAA has various ways,including photocatalysis(ultraviolet UV),ultrasonication activation(US),and activation of transition metal ions(Fe,Co,Mn,and Cu).The research results related to the removal of organic pollutants in water by PAA-based AOPs are summarized,the problems and development prospects of the coupling technology are discussed,and it can provide a reference for the development of activated PAA technology to treat new pollutants in water.
