摘　　要：超声波技术广泛应用于医疗诊断、清洗、探伤、加工、无损检测、污水处理等领域,为了给超声波污水处理试验以及实际应用时选取合适的频率、声强、温度等环境提供理论依据,对超声波空化降解机理做了研究,从理论上分析了声强、频率、温度等因素对降解效果的影响,阐述了超声波技术在废水处理领域的研究现状和进展,并对今后这方面的研究予以展望.The ultrasonic wave technology was widely used in the medical diagnosis, cleaning, detecting crack, processing, undamaged inspecting, sewage treatment, and so on. In order to provide theory basis for sewage treatment experiment as well as practical application when selecting the appropriate frequency, acoustical power, temperature, and so on, the article has done the research to the ultrasonic degeneration mechanism, theoretically analyzes the factors that effect degrading such as acoustical power, the frequency and the temperature, elaborates the present situation and the progress in the waste water processing domain of ultrasonic technology. And future research in this area is also presented.
