中文摘要：

从超声降解有机废水的机理入手，对当前单频和多频（二维正交和三维）超声以及超声技术与其他技术联用降解污水的原理、影响因素和效果和国内外研究现状进行了总结和回顾，同时对该技术在处理有机废水方面的研究趋势进行了展望。

英文摘要：

Based on the mechanism of degradation of organic waste water by ultrasonics, the principle and effect and the influencing factors in using mono-frequency or multi-frequency ultrasonics （two-dimension or three-dimension orthogonal） and the combination of ultrasonics with other technologies for the degradation both domestic and abroad overseas are reviewed. The future research trend about this technology in the degradation of organic waste water is also forecasted.
