摘　　要：吲哚散发粪便恶臭气味,广泛存在于焦化、染料、化工、制药和农药等工业废水中。由于其特殊的双环稠合结构,靠传统的生物水解断环提高吲哚的降解效果难以为继。本文全面介绍了吲哚的来源、毒性、危害及传统生物降解技术的缺陷,特别论述了高级氧化法(AOPs)中·OH的形成反应及降解吲哚的作用机理。传统AOPs能够高效降解吲哚,但价格昂贵,操作复杂,且使用剂量常受到其他物质的干扰,易引入新的污染物,难以在大规模的水处理工程中应用。因此,认为将AOPs预氧化与生物处理技术进行高效耦合是降解吲哚经济有效的办法。本文最后介绍了硫酸根自由基的高级氧化技术(SR-AOPs)耦合厌氧生物技术降解吲哚的研究及其优点。这些研究对丰富AOPs耦合生物处理技术理论、含氮杂环污染物高效降解及资源化利用有一定的参考价值。Indole widely exists in industrial wastewater such as coking,dyes,chemicals,pharmaceuticals and pesticides.Due to bicyclic fused structure of indole,it is difficult to improve the degradation efficiency of indole by traditional biohydrolysis.This paper is dedicated to offering a comprehensive picture of the indole degradation by advanced oxidation processes(AOPs).Accordingly,sources,toxicity,hazards and defects of traditional biodegradation technology are introduced.Moreover,the formation reaction of·OH in the AOPs and the mechanism of indole degradation are analyzed.Traditional AOPs can efficiently degrade indole,but they are difficult to apply in large-scale water treatment projects due to their high cost,complicated operation,and the easy introduction of new pollutants.Therefore,it is considered that the efficient coupling of AOPs pre-oxidation and biological treatment technology is a cost-effective way to degrade indole.Finally,the research on indole degradation by advanced oxidation technology of sulfate radicals(SR-AOPs)coupled with anaerobic biotechnology is introduced,along with its advantages.These studies have a reference value for enriching the theory of AOPs coupled biological treatment technology,efficient degradation and carbon resource utilization of nitrogen heterocyclic compounds(NHCs).
