过硫酸盐高级氧化技术在染料废水中的应用

Application of Persulfate Advanced Oxidation Technology in Dye Wastewater Treatment

染料废水普遍具有色度高、含盐量大,总有机碳含量高、分子量大,有毒的特点,难以用常规的生物法降解,是工业废水中公认的难处理废水之一。基于过硫酸盐的高级氧化技术因能产生有效去除难降解有机物的过硫酸根自由基(SO_(4)^(•-)),而备受人们的关注。随着研究人员不断深入地研究,过硫酸盐高级氧化体系种类也日趋丰富。论文总结了不同种类的过硫酸盐高级氧化体系在染料废水处理中的应用,分析了存在的问题及展望。

Dye wastewater generally has the characteristics of high chromaticity,high salt content,high total organic carbon content,large molecular weight and toxicity.It is difficult to be degraded by conventional biological methods.It is recognized as one of the difficult to treat wastewater in industrial wastewater.The advanced oxidation technology based on persulfate obtains much attention because it can produce persulfate radical(SO_(4)^(•-))which can effectively remove refractory organics.With the deepening of research,the types of persulfate advanced oxidation systems are becoming more and more abundant.In this paper,the application of different kinds of persulfate advanced oxidation systems in dye wastewater treatment was summarized,and the existing problems and prospects were analyzed.
