超声辐射下废水中芳香族化合物降解的研究进展

Progress of Treatment on Aromatic Compound in Wastewater by Ultrasonic Radiation

芳香族化合物广泛存在于自然环境中,性质稳定,具有很大的毒性和致癌作用,难降解,是我国优先控制的污染物.综述了近几年来国内外利用超声波辐射方法降解芳香族化合物的研究现状,并阐述了超声辐射降解芳香族化合物废水的机理.

The aromatic compounds exist in natural environment extensively. They are stable,toxic and diffcult to be degraded. Furthermore, they have cancer-causing function. The aromatic compounds are among the prior contaminants to be controlled in our country. In this paper, progresses of degradation of aromatic compounds by ultrasonic radiation are reviewed, and the mechanisms of this method are discussed as well.
