摘要
印染废水排放量大、色度高、毒性大、难生物降解,是工业废水中难处理的高浓度有机废水.本文综述了基于自由基的高级氧化技术,包括羟基自由基和硫酸根自由基两种氧化技术的原理,以及硫酸根自由基的活化方法.并介绍了这两种技术对印染废水及难降解有机污染物处理的研究,并对硫酸根自由基的高级氧化技术研究进行了展望.
Abstract
Printing and dyeing wastewater is difficult to be biodegraded because of a large discharge volume,high chromaticity,high toxicity,which is a high concentration refractory organic wastewater in industrial wastewater.This paper summarizes the advanced oxidation process based on free radicals,including hydroxyl radicals and sulfate radicals,as well as the activation methods of sulfate radical.Furthermore,the research on the treatment of printing and dyeing wastewater and refractory organic pollutants by these two technologies are introduced as well.Finally,the future trends in advanced oxidation process for sulfate radical were proposed.
