Abstract

The electro-Fenton (EF) process is a powerful electrochemical advanced oxidation process. Its development has progressed over the past three decades as a clean and effective technique for wastewater treatment. Even though conventional EF has been shown to be a powerful process for efficient degradation/mineralization of toxic and/or persistent organic pollutants; it still suffers from some downsides for industrial-scale development. Recently, research has focused on improving its effectiveness and relevance, mainly by modifying certain operating parameters; improvements in electrode material and reactor configuration, as well as coupling with other treatment methods. Therefore, this review evaluates the current state of the EF process and presents the most recent advances such as 3D-EF, chelate-EF, self-powered EF, pulsed current EF, bio-EF, sono-EF, sulfite-EF, pyrite-EF, and ferrate-EF in addition to its emerging applications like disinfection, generation of value-added products, and removal of emerging pollutants from water. The suitability of different modified or hybrid-EF processes is discussed based on their performance in H2O2 generation, degradation kinetics, mineralization efficiency and cost effectiveness. This review article is intended to be comprehensive, critical and of general interest, covering recent developments and advances in EF process with the aim of providing a powerful method for the treatment of wastewater polluted with biorecalcitrant pollutants.

电芬顿过程及其新兴应用的最新进展

摘要

电芬顿 (EF) 工艺是一种强大的电化学高级氧化工艺。作为一种清洁有效的废水处理技术,它在过去三十年中取得了长足的发展。尽管传统 EF 已被证明是有效降解/矿化有毒和/或持久性有机污染物的强大过程;它在工业规模发展方面仍然存在一些不利因素。最近,研究集中在提高其有效性和相关性,主要是通过修改某些操作参数;电极材料和反应器配置的改进,以及与其他处理方法的结合。因此,这篇综述评估了 EF 过程的当前状态,并介绍了最新的进展,例如 3D-EF、螯合物-EF、自供电 EF、脉冲电流 EF、生物 EF、sono-EF、亚硫酸盐-EF、黄铁矿-EF 和高铁酸盐-EF 以及其新兴应用,如消毒、增值产品的产生以及从水中去除新兴污染物。不同改良或混合 EF 工艺的适用性根据它们在 H 中的性能进行了讨论2 O 2生成、降解动力学、矿化效率和成本效益。这篇评论文章旨在全面、批判和普遍关注,涵盖 EF 工艺的最新发展和进步,旨在提供一种强大的方法来处理被生物顽固污染物污染的废水。
