功率超声在废水处理中的应用

Application of power ultrasound in waste water treatment

采用不同强度和频率的超声波,对几种生物难降解的有毒污染物（苯胺,硝基苯）废水进行超声处理,实验表明,降解效果主要取决于超声波在反应液中的声强及处理时间,同时,若辅以通氧气或加入催化剂,处理效果更好,这就为设计相应的超声废水处理设备提供了实验基础。

Through the alternation of frequency and intensity of ultrasonic. The degradation of hard biodegradable and toxic pollutant (Nitrobenzene and Aniline) were studied. The results show that. The degradation rate depends on the intensity and acting time of Ultrasound, In the presence of oxygen and calalst (Fenton). The efficiency was improved largely. These studies will be useful to the design of Ultrasonic water-treatment apparatus.
