Research Progress on Fenton oxidation mechanism in organic wastewater treatment

芬顿反应工艺是目前公认处理有机废水最有效的方法之一,而探索其反应机理对于高效芬顿催化反应体系的开发和应用至关重要。芬顿反应的复杂性导致其反应机理仍未得到完整的解释。该文综述了目前较受认可的均相芬顿、光助芬顿、电助芬顿和多相芬顿的反应机制,旨在帮助研究者比较全面及深入地认识不同体系中芬顿反应的机理,为芬顿反应的发展提供理论支撑。最后对芬顿过程的未来发展方向进行了展望。

Fenton oxidation is currently recognized as one of the most effective methods for organic wastewater treatment.And exploration on its reaction mechanism is crucial for the development and application of efficient Fenton processes.However,the mechanism is not fully clarified yet due to the complexity of Fenton reaction.In this review,the reaction mechanisms of homogeneous Fenton,photo-Fenton,electro-Fenton and heterogenetic Fenton in removal of organic pollutants were summarized to help researchers and engineers gain a comprehensive and in-depth understanding of the Fenton reaction mechanism in different systems,thus providing theoretical support for the development of Fenton reaction.Finally,the future development directions of Fenton process were discussed.
