负载型Fenton催化剂处理有机废水的研究进展

Research progress in the treatment of organic wastewater by supported Fenton catalyst

近年来,采用Fenton反应高效处理废水中的有机物引起了广泛关注。传统Fenton反应存在产生铁泥和适用p H范围比较小等问题,目前的研究倾向于选择稳定的Fenton催化剂进行非均相反应。综述了近年来非均相Fenton催化剂的制备及应用情况,其载体主要包括碳基、分子筛、黏土等,并讨论了催化剂的活性、稳定性以及对有机物污染物的降解机理。

In recent years,attention has widely been paid to the utilization of Fenton reaction for treating the organic substances in wastewater efficiently. The traditional Fenton reaction had problems ,such as producing iron sludge , having narrow suitable range for pH,etc. The present research is inclined to choose stable Fenton catalyst for carrying out heterogeneous reaction. The preparation and application of heterogeneous Fenton catalyst in recent years are summarized. Its carriers mainly consist of carbon-based materials,zeolite,clay,etc. The activity and stability of the catalyst and degradation mechanism of organic pollutants are discussed.
