摘　　要：高级氧化技术(AOPs)是目前很受人们关注的新型水处理工艺,特别是对难降解有机废水有其独到之处。着重介绍了Fenton法及类Fenton法、光化学氧化法和光催化氧化法、臭氧氧化法、电化学氧化法、湿式氧化法和湿式催化氧化法、超临界水氧化法及超临界水催化氧化法在水处理中的作用机理和研究进展。如何产生更多的羟基自由基(.OH)是AOPs面临的一个主要问题。研究价格低廉、氧化效率好的氧化剂和催化性能好、稳定性强的催化剂是今后AOPs的主要发展趋势。Advanced oxidation processes （AOPs）, as new technologies in water treatment fields, are very popular in recent years. Especially, AOPS have the advantage in the treatment of difficultly degraded organics. The research process and mechanism for water treatment by advanced oxidation processes, such as Fenton and technologies on Fenton, photochemical oxidation and photocatalysis oxidation, ozone oxidation, electrochemical oxidation, wet air oxidation and catalytic wet air oxidation, supercritical water oxidation and supercritical catalytic water oxidation, are summarized in this paper. How to produce more ·OH radicals is one of the most radical issues in AOPs. Comprehensive analysis manifests that researching the oxidants of higher cost-efficient as well as the catalysts of more catalytic activity and sustainable are the main development trend in AOPs. In addition, it is necessary that technologies which combine AOPs and sound, light, electricity, magnet and so on will further not only enhance wastewater removal but also expand its space for research in wastewater fields.
