摘要
臭氧对生化降解性差的有机废水和废水生化处理后的微污染物可以有效地氧化降解。但臭氧处理技术存在设备和运行费用较高,臭氧利用率较低等缺陷,因此臭氧耦合技术应运而生,并且部分臭氧耦合技术已经广泛应用于给水和污废水处理。系统总结了臭氧联合技术在废水处理领域的应用和发展,并着重介绍了臭氧联合技术中的金属催化臭氧氧化技术在废水处理领域的现状和前景。通过比较均相催化臭氧氧化和非均相催化臭氧氧化技术,指明了未来废水处理领域金属催化臭氧氧化技术的发展方向。
The ozone can effectively oxidatively degrade the organic wastewater with poor biodegradability and the micro-pollutants after the biochemical treatment of the wastewater.However,the ozone treatment technology has the disadvantages of high equipment and operating costs,low ozone utilization,etc.Therefore,the ozone coupling technology emerges as the times require.And part of the ozone coupling technology has been widely used in water supply and sewage treatment.The application and development of ozone in the field of wastewater treatment,advantages and disadvantages,and the status and prospects of metal-catalyzed ozone oxidation in the field of wastewater treatment were discussed in this article.Additionnally,the article pointed out the development direction of metal-catalyzed ozonation technology in the field of wastewater treatment in the future by comparing the homogeneous and heterogeneous catalytic ozonation technologies.
