中文摘要：

采用空气鼓泡结合玻璃珠（鼓泡空化）的方法,对酸性红B等染料的降解进行了研究,考察了各种因素（鼓泡时间,初始浓度,玻璃珠直径,溶液酸度和气体流速等）对酸性红B降解的影响.结果表明,在室温（25℃）条件下,当鼓泡时间为5.0h、溶液初始浓度为10mg·mL^-1、玻璃珠直径为3.0～3.5mm、溶液酸度pH=6.0和气体流速4.5L·min^-1时,酸性红B的降解率可达97%以上.同时,还初步探讨了鼓泡空化的形成过程和降解有机污染物的机理,推测是气泡融合时气泡之间的内壁张力达到极限致使气泡破裂,放出大量能量,使水（H2O）和氧气（O2）反应生成氧化性极强的氢氧自由基（·OH）和超氧自由基（·O2^-）,使溶液中的有机污染物降解.

英文摘要：

Investigations into the degradation of dyes such as acid red B were carried out using air bubbling combined with glass balls （ bubbling cavitation）. In addition, the effects of bubbling time, ioitial concentration, glass ball diameter, solution acidity and gas flow rate on the degradation of acid red B were studied. The results showed that the degradation ratio of acid red B reached over 97% for a 5.0 h bubbling time, 10 mg· L^-1 initial concentration, 3.0- 3. 5 mm glass balls, pH = 6.0 and 4.5 L· min^-1 gas flow rate at room temperature （25℃）. Meanwhile, the mechanism of bubbling cavitation and the degradation mechanism of organic pollutants are discussed. We propose that when two small bubbles collapse into a large one, the inner wall tension between the bubbles reaches a maximum so that the bubbles break. The large amount of energy released in the process induces H2O and O2 to form · OH and · O2^- radicals which are strongly oxidizing. Thus, the organic pollutants in the solution are degraded.
