水处理高级氧化技术研究进展

随着水污染问题的日益严重,可以产生大量自由基的高级氧化技术(AOPs)得到了越来越多人们的关注。对Fenton氧化法、臭氧氧化法、湿式氧化法、光催化氧化法、超临界水氧化法、超声波氧化法及过硫酸盐氧化法在废水领域的研究现状与发展进行了详细介绍。如何产生更多的羟基自由基(·OH)是AOPs应着手解决的首要问题。研究成本低廉、氧化效率良好的氧化剂和催化性能优异、稳定的催化剂以及高级氧化联合技术的开发是未来AOPs的主要发展趋势。

Research Progress in Advanced Oxidation Technology for Water Treatment

With the increasing problem of water pollution, advanced oxidation technologies (AOPs), which can generate a large amount of free radicals, have attracted more and more attention. This paper introduces the reaction mechanism and research progress of common advanced oxidation technology in wastewater treatment process. How to generate more hydroxyl radicals (.OH) is the primary problem that AOPs should solve. In the future, the main development trends of AOPs are as follows: The development of oxidants with low cost and good oxidation efficiency; excellent and stable catalysts; advanced oxidation combined technology.
