Abstract：
The global focus on wastewater treatment has intensified in the contemporary era due to its significant environmental and human health impacts. Pharmaceutical compounds (PCs) have become an emerging concern among various pollutants, as they resist conventional treatment methods and pose a severe environmental threat. Advanced oxidation processes (AOPs) emerge as a potent and environmentally benign approach for treating recalcitrant pharmaceuticals. To address the shortcomings of traditional treatment methods, a technology known as the electro-Fenton (EF) method has been developed more recently as an electrochemical advanced oxidation process (EAOP) that connects electrochemistry to the chemical Fenton process. It has shown effective in treating a variety of pharmaceutically active compounds and actual wastewaters. By producing H2O2 in situ through a two-electron reduction of dissolved O2 on an appropriate cathode, the EF process maximizes the benefits of electrochemistry. Herein, we have critically reviewed the application of the EF process, encompassing diverse reactor types and configurations, the underlying mechanisms involved in the degradation of pharmaceuticals and other emerging contaminants (ECs), and the impact of electrode materials on the process. The review also addresses the factors influencing the efficiency of the EF process, such as (i) pH, (ii) current density, (iii) H2O2 concentration, (iv) and others, while providing insight into the scalability potential of EF technology and its commercialization on a global scale. The review delves into future perspectives and implications concerning the ongoing challenges encountered in the operation of the electro-Fenton process for the treatment of PCs and other ECs.
摘要：
由于废水处理对环境和人类健康的重大影响，全球对废水处理的关注在当代得到了加强。药物化合物（PC）已成为各种污染物中新兴的问题，因为它们抵制传统的处理方法并构成严重的环境威胁。高级氧化过程（AOPs）是一种有效且对环境无害的方法，用于治疗顽固性药物。针对传统治疗方法的不足,作为将电化学与化学Fenton工艺连接的电化学高级氧化工艺(EAOP),最近开发了一种称为电-Fenton(EF)法的技术。它已显示出有效处理多种药物活性化合物和实际废水。通过在适当的阴极上通过溶解的O2的两电子还原原位产生H2O2，EF过程最大化电化学的好处。在这里，我们已经严格审查了EF流程的应用，包括不同的反应堆类型和配置，涉及药物和其他新兴污染物(EC)降解的潜在机制，电极材料对工艺的影响。审查还讨论了影响EF过程效率的因素，如（i）pH值，(ii)电流密度，(iii)H2O2浓度，(iv)及其他,同时深入了解EF技术的可扩展性潜力及其在全球范围内的商业化。该审查探讨了未来的观点和影响，这些观点和影响涉及在处理PC和其他EC的电子Fenton过程的操作中遇到的持续挑战。
