超声与臭氧协同作用对水中污染物的脱除研究

Studies on removal of water pollutants by synergistic reaction of ultrasonic and ozone technology

采用超声、臭氧和两种方法联用技术,进行废水中对硝基苯酚等几种有机污染物的降解研究。超声和臭氧具有明显的协同作用,联合起来使用,可有效提高有机污染物去除率。降解曲线基本上符合一级动力学方程,线性相关系数大于0.99。

Ultrasonic, ozone and their synergetic technique were employed respectively for degradation of water pollutants. It was found that the combination of ultrasonic and ozone possessed significant synergetic effect on the degradation, and the removal rate of organic pollutants was improved compared with the re- sults of the single methods of ultrasonic and ozone. The degradation followed first-order kinetics, the linear correlation coefficient was more than 0.99.
