摘要
在基于硫酸根自由基(SO_(4)^(·-))的高级氧化水处理技术中,SO_(4)^(·-)的来源主要集中于过硫酸盐,关于亚硫酸盐〔S(Ⅳ)〕的报道较少。对比分析了S(Ⅳ)和过硫酸盐(PS)产生自由基的特点,总结了由S(Ⅳ)活化产生SO_(4)^(·-)降解有机物的机理,介绍了过渡金属活化、光活化、电活化以及多种方式联合活化等方法活化S(Ⅳ)并用于废水处理的最新研究进展,讨论了不同活化方法的差异,并对基于S(Ⅳ)活化产生SO_(4)^(·-)的高级氧化水处理技术未来的研究方向进行了展望。
In the sulfate radical(SO_(4)^(·-))-based advanced oxidation process for water treatment,the main source of SO_(4)^(·-)mainly focuses on persulfate(PS),however,there are few reports about sulfite〔S(Ⅳ)〕.The characters of S(Ⅳ)and PS based advanced oxidation process were comparatively analyzed,and the production mechanism of SO_(4)^(·-)by S(Ⅳ)to degrade organic matters were summarized.Also,the mechanisms of the transition metal activa⁃tion,photo activation,electricity activation and combined activation methods were elaborated in detail,and the dif⁃ferences between activation methods were discussed.Moreover,the future research direction of advanced oxidation process based on S(Ⅵ)activation to produce SO_(4)^(·-)for water treatment was prospected.
