Abstract

Fenton process is a highly promising technology for wastewater treatment, but its operational potential is limited by pH sensitivity and excessive sludge production. The bio-electro-Fenton (BEF) system combines the cost-effectiveness of biotechnology with the sludge reduction effects of electro-Fenton, offering greater economic benefits and treatment potential compared to other enhanced Fenton processes. However, challenges persist in terms of stringent pH control, low electricity production efficiency, and limited reaction efficiency when applied at a large scale. Therefore, this paper introduces the BEF mechanism, examines key factors influencing its efficiency in terms of biological and catalytic performance, and highlights recent innovations in electrode materials, catalysts, and reactor design. The discussion focuses on the challenges and limitations faced by the BEF system in catalysts and reactor configurations for large-scale industrial applications. Strategies are proposed to overcome key technical constraints and enhance the cost-effectiveness of the process. It is recommended to integrate BEF with biological methods, develop highly efficient catalysts, and leverage modeling technologies such as Matlab/Simulink and artificial neural networks to accelerate the full-scale application of BEF technology.

期刊介绍： The Journal of Electroanalytical Chemistry is the foremost international journal devoted to the interdisciplinary subject of electrochemistry in all its aspects, theoretical as well as applied. Electrochemistry is a wide ranging area that is in a state of continuous evolution. Rather than compiling a long list of topics covered by the Journal, the editors would like to draw particular attention to the key issues of novelty, topicality and quality. Papers should present new and interesting electrochemical science in a way that is accessible to the reader. The presentation and discussion should be at a level that is consistent with the international status of the Journal. Reports describing the application of well-established techniques to problems that are essentially technical will not be accepted. Similarly, papers that report observations but fail to provide adequate interpretation will be rejected by the Editors. Papers dealing with technical electrochemistry should be submitted to other specialist journals unless the authors can show that their work provides substantially new insights into electrochemical processes.
