摘要
超声与臭氧联用在处理水中难降解有机物方面具有广阔的应用前景。归纳了超声与臭氧联用处理各种难降解有机物的概况、氧化机理和模型发展,介绍了超声与臭氧联用处理各种难降解有机污染物的中间产物,分析了臭氧投加量、pH值和难降解有机物的初始浓度对降解过程的影响,最后针对该技术存在的问题提出了今后的研究方向。
The combined ultrasonic-ozone process is the most promising method for treating refractory organics in waste water. The degradation of refractory organics by using the combined ultrasonic-ozone process, oxidation mechanism, and model development are reviewed. The intermediates and the effects of ozone dosage, pH and the initial concentration of refractory organics are introduced. Finally, the research directions are indicated based on the problems of the combined ultrasonic-ozone process.
