摘　　要：活化过硫酸盐氧化法是处理废水中有机污染物的重要手段,该法是通过活化过硫酸盐产生硫酸根自由基和羟基自由基对污染物进行有效降解。由于单一的活化方式具有一定的局限性,即可将不同的活化方式相结合,使其产生协同作用,超过单独使用某种活化方式的去除效果。综述了过硫酸盐高级氧化的相关活化技术,阐述了过渡金属与热联合活化、紫外与超声联合活化、碱与热联合活化等不同方式联合活化的作用机理,并结合联合活化过硫酸盐的应用现状,对该技术的发展前景作出展望,为同类问题的研究提供一定的借鉴与思考。Activated persulfate oxidation is an important method to treat organic pollutants in wastewater.This method can effectively degrade pollutants by activating persulfate to generate sulfate radicals and hydroxyl radicals.Because a single activation mode has certain limitations,different activation modes can be combined to produce synergistic effects,exceeding the removal effect of a certain activation mode alone.In this paper,the related activation technologies of advanced oxidation of persulfate were summarized,the mechanisms of transition metal and heat combined activation,ultraviolet and ultrasonic combined activation,alkali and heat combined activation were expounded,and combined with the application status of combined activated persulfate,the development prospect of this technology was prospected,providing some reference and thinking for the research of similar problems.
