摘要
臭氧(O_3)是一种强氧化剂,具有良好的杀菌消毒和降解污染物的能力,但臭氧与有机物的反应是选择性的。超声降解水体中有机污染物是近年来兴起的一项极具发展前景的新型水处理技术,能有效地降解废水中的难降解有机污染物。将超声与臭氧进行联合使用,可以提高降解有机物的效率。文章介绍了超声/臭氧联用技术降解有机物的机理,综述了国内外超声/臭氧联用技术在废水处理中的研究进展。并指出超声联合臭氧技术今后需解决的问题和发展方向。
Ozone is a very strong oxidant with good ability in disinfection, oxidization and degradation of pollutants. However, ozone selectively oxidizes organics. As a new technology of organic pollutant degradation, the ultrasonic method, which effectively decomposes nondegradable pollutants, is becoming increasingly important in wastewater treatment. Degradation is enhanced by ozone with ultrasonic. The mechanism of degradation is investigated, and recent advances in wastewater treatment using this integrated method reviewed. Problems to be solved and the direction of future development in applications of the combined ultrasound and ozone techniques in wastewater treatment are pointed out.
