摘要

本研究通过半批量实验研究了臭氧微泡(OMBs)在初始溶液pH、臭氧生成速率和初始mo浓度等不同反应条件下处理亚甲基橙水溶液的效率。结果表明:在酸性和碱性介质下,OMBs对MO的去除率都很高,当臭氧生成速率由0.498 mg/s提高到0.83 mg/s时,去除率在15 min内由75%显著提高到100%,氧化反应速率符合准一级动力学模型。结果表明,OMBs在降低亚甲基橙浓度和亚甲基橙总矿化方面是有效的。

Investigation of Ozone Microbubbles for the Degradation of Methylene Orange Contaminated Wastewater
In the present study, semi – batch experiments were conducted to investigate the efficiency of ozone microbubbles (OMBs) in the treatment of aqueous dye solutions methylene orange under different reaction conditions such as  effect of initial solution pH , ozone generation rate and initial MO-concentration. The results showed that the removal of MO by OMBs were very high at the acidic and alkaline media and upon increasing the generation rate of ozone from 0.498 to 0.83 mg/s, the removal efficiency dramatically increased from 75to 100% within 15 min. The rate of oxidation reaction followed a pseudo first- order kinetic model. The results demonstrated that OMBs is efficient in terms of the decline of methylene orange concentration and its total mineralization.
