摘　　要：介绍了过硫酸盐活化机理,综述了硫酸根自由基的产生途径,通过不同过硫酸盐活化方法如:热活化、碱活化、紫外光活化、过渡金属离子活化、微波活化、金属氧化物活化等方法可以产生硫酸根自由基,并且能够有效处理有机废水。基于硫酸根自由基的高级氧化技术拥有良好的应用前景,但该技术仍存在许多问题且具有一定的局限性。未来需要增加基于硫酸盐自由基的高级氧化工艺在实际情况下真实有机废水中的净化实验并且开发出价格低廉、处理高效、稳定且易回收的新型催化剂,探究天然有机物的催化性能,降低应用成本和二次污染。The mechanism of persulfate activation is introduced,and the production pathway of sulfate radical is reviewed.Sulfate radical can be produced by different persulfate activation methods,such as thermal activation,alkali activation,UV activation,transition metal ion activation,microwave activation,metal oxide activation,etc.,and can effectively treat organic wastewater.The advanced oxidation technology based on sulfate radical has a good application prospect,but it still has many problems and some limitations.In the future,it is necessary to increase the purification experiments of advanced oxidation process based on sulfate free radicals in real organic wastewater and develop new catalysts with low price,high efficiency,stability and easy recovery,so as to explore the catalytic performance of natural organic compounds and reduce application costs and secondary pollution.
