摘要
针对目前比较关注的致嗅物质污染问题,选用Fenton高级氧化技术研究了其对水中致嗅物质2-甲基异莰醇(2-MIB)的去除,探讨了Fenton反应对水中致嗅物质的去除效能及H2O2/Fenton摩尔比、Fe2+浓度、反应时间和溶液pH值各因素对氧化反应的影响。提出了Fenton氧化反应去除2-MIB的最佳反应条件。实验结果表明:Fenton高级氧化能有效去除水中的2-MIB。在H2O2/Fenton摩尔比为3.0、Fe2+浓度10 mg/L、反应时间10 min和溶液pH值为3.0时,去除效率达到97.9%。Fenton氧化反应的操作条件(浓度、pH值等)比较容易实现,因此Fenton氧化技术在实际污染处理中有很大的应用前景。
Aimed at the pollution problem of substance that cause odor in water has been greatly concerned by many people in recent days,the paper investigated the removal of odor-causing substance such as 2-methyl isobutyl（ 2-MIB） by Fenton advanced oxidation process,and studied the effectiveness of the Fenton oxidation,the effect of various factors such H2O2： Fe2 ＋molar ratio,Fe2 ＋concentration,reaction time and solution pH on removal efficiency. The optimum condition of Fenton advanced oxidation process for removal of 2-MIB was proposed. In summary,Fenton oxidation is effective for removing 2-MIB. Removal efficiency reached as high as 97. 9% at conditions of H2O2/ Fenton ratio of 3. 0,Fe2 ＋concentration of 10 mg / L with reaction time of 10 min and solution pH of 3. 0. Overall,these conditions are relatively easy to realize which means that Fenton process shows wider promise in the treatment of pollutant.
