水处理高级氧化技术研究进展

Research Progress in Advanced Oxidation Technology for Water Treatment

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。

With the increasingly severe water pollution,more and more attention have been paid to advanced oxidation processes( AOPs) which can generate a large amount of free radical. A detailed overview of the research status and development of Fenton oxidation,ozonation,wet oxidation,photocatalytic oxidation,supercritical water oxidation,ultrasonic oxidation and persulphate oxidation in the waste water field were presented. It is of the utmost importance for AOPs to generate more hydroxyl radical(·OH). It will be the main development tendency for AOPs to study oxidizer with low cost and good oxidation efficiency,stable catalyzer of good performance and advanced oxidation combination technology.
