摘　　要：通过研究提出了一种相对经济安全高效的处理高浓度、难降解有机污水“超声聚焦裂解”新方法,即利用超声波作用使污水中的微气泡产生空化泡崩溃现象,对液体中的一些大分子物质进行超声裂解。通过对液体的结构强度、空化阈和空化泡崩溃时间的研究,提出了通过动态加压溶气的方法,来提高液体中的溶气量;从节约能源,提高场强角度出发又提出了超声聚焦方法;通过研究构建了超声裂解动力学模型。在理论研究的基础上设计了一套实验装置,并通过实验研究,进一步深入地探讨了有机污水超声裂解效果和影响因素,为经济高效地处理高浓度、难降解有机污水探索了一条新途径。According to organic wastewater of high consistence and difficult decomposition, a new ultrasonic focalize decomposition method is provided. In this article, the ultrasonic is used to generate micro-bubble with ultrasonic cavitation effect. On this effect, some big molecules in fluid are decomposed. Through studying on theliquid structure strength, cavitation value and collapse time of cavitation bubbles, the dynamic adding pressure and dissolving air method are advanced to increase the amount of air in fluid. To save energy and enhance field intensity, ultrasonic focalization is applied. Then the dynamic model of ultrasonic focalization decompesition is constructed. Based on the theory research, a experiment device is designed. We use to do some experiments. It is a new way to process the organic wastewater of high consistence and difficult decomposition.
