摘要:

研究了玻璃珠对超声空化效应的强化作用,探讨了玻璃珠粒径、剂量对超声辐照纯水产生H2O2的影响,研究了玻璃珠对超声氧化降解染料废水中亚甲基蓝的强化效果.结果表明,玻璃珠的加入能够强化超声空化作用.当玻璃珠粒径为0.120 mm、投加质量浓度为10 g/L时超声空化效果最好,H2O2的产量提高了1.8倍.在此条件下,超声氧化降解亚甲基蓝的去除率可达73.8%.

Abstract:

The enhancing effect of ultrasonic cavitation by adding glass balls has been studied. The influences of the granular size and dosage of glass balls on the yield of H2O2,which was produced from ultrasonic irradiation on pure water,are discussed,and the enhancing effect of glass balls on ultrasonic degradation of methylene blue contained in dyeing wastewater has been investigated. The results show that the addition of glass balls can enhance ultrasonic cavitation effect. The ultrasonic cavitation effect is the best,the yield of H2O2 increases 1.8 times,when the granular size of glass balls are 0.120 mm,and its mass concentration is 10 g/L. Under these conditions,the removing rate of methylene blue by ultrasonic oxidation degradation can reach 73.8%.

Key words: ultrasonic cavitation, glass balls, hydrogen peroxide, methylene blue
