摘要
概述了超声空化技术的国内外研究现状;介绍了超声空化技术的机理,超声场、溶液初始浓度、溶液pH值、溶液温度及溶液中溶解气体等因素对超声空化技术的影响;并对我国造纸工业污染存在的主要问题进行了简单的介绍;最后对超声空化技术降解造纸废水方面的应用进行了举例描述,并对该技术的应用前景进行了展望。
The present research situation of ultrasonic cavitation technology at home and abroad is outlined. The mechanism of ultrasonic cavitation and the influence of ultrasonic field, initial concentration, pH and temperature of solution and dissolved gases in solution on ultrasonic cavitation effect are introduced. The main problems of the pollution of China＇s paper industry are briefly introduced. Finally, the application prospect of the ultrasonic cavition technology in papermaking waste water treatment is described.
