| 摘 要： | 活化过硫酸盐氧化法因具有经济、高效、环保、安全稳定等优势，近年来在酚类污染物的降解中备受关注。目前活化过硫酸盐降解酚类污染物的方法主要包含外加能量活化和外加催化剂活化两大类。其中单一的热活化、光活化、超声活化、电化学活化、等离子体活化等外加能量活化过程能量消耗较大，且对酚类污染物不易达到满意的降解效果。过渡金属活化和碳质材料活化等外加催化剂活化方式，由于环境污染小、操作成本低、降解率高等优点，越来越受到科研工作者的重视。为了提高对酚类污染物的降解率，不同的过硫酸盐活化方式不断融合，逐渐形成多种耦合活化方式，例如，碳质材料与过渡金属的耦合活化、电化学与过渡金属催化剂的耦合活化以及光与外加催化剂的耦合活化等。本文论述了活化过硫酸盐氧化法降解酚类污染物的研究进展，概述了活化过硫酸盐的影响因素，分析了活化过硫酸盐降解酚类污染物存在的问题，展望了活化过硫酸盐降解酚类污染物的发展方向。

| Abstract: | The degradation of phenolic pollutants by activated persulfate (PS) has attracted much attention due to its economical, efficient, environmentally friendly, safe and stable advantages. Presently, there are two main activated methods for PS such as external energy and catalyst activation. The single external energy activation for PS which contains heat, light, ultrasound, electrode and plasma activation, etc. exhausts more energy but gains poor degradation effect of phenolic pollutants. More and more researchers begin to focus on external catalyst activation of PS owing to its little environmental pollution, low operation cost and high degradation efficiency. In order to increase the degradation efficiency of phenolic pollutants, different activation methods of PS gradually have mixed together and they finally have brought about hybrid technologies such as combination of carbon materials and transition metals, combination of electrode and transition metals, and combination of light and catalysts. The research progress on degradation of phenolic pollutants by activated PS were reviewed systematically. Then, the influencing factors of activated PS were sketched. Furthermore, the existing problems of degradation of phenolic pollutants by activated PS were analyzed. Finally, the development trends of degradation of phenolic pollutants by activated PS were forecasted. |
