摘　　要：文章主要从动力学角度论述了超声波降解有机污染物的机理及其降解途径,分析影响有机物超声降解效果的基本因素,如粘度、表面张力系数、蒸汽压、温度、溶解气体、超声频率、声功率及pH等;并描述了超声波在水处理领域,特别是与传统生物处理法联用处理难降解、有毒有机废水方面的发展应用前景。The mechanism of ultrasonic degrading of organic contaminants and the way of degradation are studied from the kinetic point of view. Some basic factors which affect the efficiency of degradation such as viscosity,coefficient of surface tension,steam pressure,temperature,dissolved gas,ultrasonic frequency,power and pH are analyzed. The application prospect of ultrasound in the field of wastewater disposal is described,especially the prospect of the ultrasonic method combining with the biological method in treating the toxic organic wastewater hard to degrade.
