Abstract

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fenton工艺研究进展及应用前景

电- fenton (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污水处理技术，它的发展在过去的三十年中取得了进展。尽管传统环境污染已被证明是有效降解/矿化有毒和/或持久性有机污染物的有力过程;在工业规模发展方面，它仍然存在一些缺点。最近，研究的重点是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耦合。因此，本文评估了EF工艺的现状，并介绍了最近的进展，如3D-EF、螯合-EF、自供电EF、脉冲电流EF、生物-EF、声波-EF、亚硫酸盐-EF、黄铁矿-EF和高铁酸盐-EF，以及它在消毒、产生增值产品和去除水中新污染物等方面的新兴应用。从H2O2生成性能、降解动力学、矿化效率和成本效益等方面讨论了不同改性或混合ef工艺的适用性。这篇综述文章的目的是全面的，关键的和普遍感兴趣的，涵盖了EF工艺的最新发展和进展，目的是为处理被生物顽固性污染物污染的废水提供一个强有力的方法。图形抽象

期刊介绍： Two of the most pressing global challenges of our era involve understanding and addressing the multitude of environmental problems we face. In order to tackle them effectively, it is essential to devise logical strategies and methods for their control. Critical Reviews in Environmental Science and Technology serves as a valuable international platform for the comprehensive assessment of current knowledge across a wide range of environmental science topics. Environmental science is a field that encompasses the intricate and fluid interactions between various scientific disciplines. These include earth and agricultural sciences, chemistry, biology, medicine, and engineering. Furthermore, new disciplines such as environmental toxicology and risk assessment have emerged in response to the increasing complexity of environmental challenges. The purpose of Critical Reviews in Environmental Science and Technology is to provide a space for critical analysis and evaluation of existing knowledge in environmental science. By doing so, it encourages the advancement of our understanding and the development of effective solutions. This journal plays a crucial role in fostering international cooperation and collaboration in addressing the pressing environmental issues of our time.
