摘　　要：利用超声技术降解水中有机污染物是近年来备受关注的热点之一。超声空化产生三个区域:气泡内部、气液界面和本体溶液,为有机物的降解提供了适宜的物理化学环境,但降解效率也受到多重因素的影响,如超声频率及能量、温度、pH和空化气体等。因此,利用超声与臭氧氧化、电化学氧化、光催化氧化、芬顿技术联用产生协同作用,能够更加高效降解水中有机污染物。此外,本文综述了近年来超声及其联合技术处理水体中各种有机染料、农药和抗生素等典型的难降解有机物的研究进展。The use of ultrasonic technology to degrade organic pollutants in water has been one of the hot topics that has attracted much attention in recent years.Ultrasonic vacuum produces three areas:the interior of the bubble,the interface of the gas and liquid,and the body solution,which provides a suitable physical chemical environment for the degradation of organic matter,but the degradation efficiency is also affected by multiple factors,such as the frequency and energy,temperature,pH,and empty gas and so on.Therefore,the use of ultrasonic and oxidation,electrochemical oxidation,photocatalytic oxidation,and Fenton technology to produce synergy,which can more efficiently degrade organic pollutants in water.In addition,this article reviews the research progress in recent years in the treatment of typical refractory organic pollutants in water such as various organic dyes,pesticides and antibiotics using ultrasound and its combined technology.
