摘要
文章简要介绍了超声波主要作用机理:机械效应、空化作用、热效应,论述了超声波作用的主要影响因素,即介质理化性质、超声系统参数及超声波反应器条件等,并分析了超声波技术在当代水处理中降解有机物的应用,考察了超声波技术与多种水处理技术协同作用的应用现状并展望了该技术的应用前景和需要解决的问题。
The mechanism of ultrasonic is briefly introduced in this paper.The main mechanism including mechanical effect,cavitations and heating effect is further explained.Factors of ultrasonic effect,viz,the chemical and physical properties of media、system parameter and the condition of reactor are also discussed in the paper.The application of ultrasonic removal of organic matters is compendiously introduced and a review of present application with cooperation between ultrasonic and other water treatment technology is made in the paper.
