超声与其他技术联合在废水处理中的应用

Application of the combinations of ultrasonic and other techniques to wastewater treatment

超声是一种处理有机污染物废水的新型技术,近10a来,超声降解水体中有机污染物的研究十分活跃,但由于此技术存在着费用高、降解效率低等一些局限性,而更有效的方法是将超声技术与其他水处理技术联合使用。所以作者系统地介绍了超声/臭氧法、超声/紫外/臭氧法、超声/过氧化氢法、超声/Fenton试剂法、超声/光化学法、超声/电化学法、超声/磁化学法、超声/湿法氧化法、超声/生物法、超声/脱附法等联用技术在水处理中的应用研究现状,并展望了今后的重点研究方向。

Ultrasonic is a new technique to destroy organic pollutants in water,in the last ten years,the study on the degradation of organic pollutants in water by ultrasonic is very active. However, owing to some limits of this technique, such as high power and low efficiency in degradation,more effective ways are in combinations with other wastewater treatment techniques. The paper systemically introduces some united techniques, such as US/O3,US/UV/O3,US/H2O2,US/Fenton,sonoelectrochemistry,sonophotochemistry,sonomagnetchemistry,SONIWO and so on. Finally, the future research emphasis are viewed.
