本文论述了超声波(US)降解有机污染物技术的原理和效果、国内外现状与发展趋势，指出超声波的“空化”作用是其主要的作用机制，超声波与其它作用（紫外光辐射、催化氧化等联合运用），可以大大加速和提高有机污染物的矿化度，在处理难降解和有毒、有害有机污染物方面，特别是在净化环境、处理优先控制污染物方面有巨大的应用前景。
Abstract
The technique of degradation of organic pollutants by ultrasound is described, including its principle, effect and development at home and abroad. The interaction mechanism is Dased on the cavita?tion .Ultrasound technology,combined with ultraviolet irradiation, catalysis and oxidation, can greatly in?crease the degree of mineralization organic pollutants. The procedure has eminent prospects in the degrada?tion of unbiodegradable，toxic and hazardous organic pollutants，especially on those of environmental priori?
