活化过硫酸盐体系降解去除水中有机污染物的研究进展

Study on the progress in degradation of organic pollutions in water by persulfate activation based processes

近年来,基于活化过硫酸盐(Persulfate,PS)的高级氧化技术因其操作简单和高效环保而被广泛应用于降解水体中多种有机污染物.总结了活化PS的方式以及其降解去除有机污染物的主要影响因素如pH、PS和活化剂剂量等,梳理了活化PS高级氧化技术降解去除有机污染物的自由基和非自由基两种主要机制,并分析了活化PS高级氧化技术当前可能存在的问题和展望了未来的发展方向.

In recent years,persulfate(PS)activation based advanced oxidation technology has been widely used to degrade various organic pollutants in water due to its simple operation,high efficiency and environmental friendliness.In this paper,the ways of activating PS and the effects of the main factors including pH,PS and activator dosage on the degradation of organic pollutants were summarized,and the free radical mechanism and non-free radical mechanism of the degradation of organic pollutants by activating PS process was discussed.Finally,the possible problems of PS activation based advanced oxidation technology at present and to the future development direction were also discussed.
