超声协同Fenton法处理有机废水的研究进展

超声协同Fenton法是利用超声的空化效应及自由基效应强化Fenton法对废水的处理效率,实现两者对废水中有机污染物的协同降解。概述了超声与Fenton法处理废水的协同机制。综述了废水pH、催化剂和H₂O₂投加量、超声功率、温度等工艺条件的优化研究,催化剂的研发以及共存物质的影响研究等方面的进展。指出开发新型高效、可重复利用、廉价易得的催化剂是提高超声协同Fenton法降解有机污染物效率的关键,还可将超声、Fenton法或超声协同Fenton法与其他的氧化法或生化方法相结合,寻找更加安全、高效、低成本的新途径。

Research advances in organic wastewater treatment by ultrasound-Fenton synergy method

With the cavitation effect and free radical effect of ultrasound,the ultrasound-Fenton synergy method can improve the wastewater treatment efficiency by Fenton method,and thus the synergetic degradation of organic pollutants in wastewater is achieved. The synergistic mechanism of ultrasound and Fenton in wastewater treatment is summarized. And the advances in optimization of process conditions（such as：wastewater pH,catalyst and H₂O₂ dosage,ultrasonic power,temperature,etc.）,development of catalyst and research of coexisting substance effect are reviewed. It is pointed out that the development of new,efficient,reusable,cheap and available catalyst is the key to increase the degradation efficiency of organic pollutants by ultrasound-Fenton synergy method. And the ultrasound method,Fenton method,or ultrasound-Fenton synergy method can be also combined with other oxidation or biochemical methods for a new process with high safety,high efficiency and low cost.
