摘要:

随着工业化进程加快,废水的类型和排放量日益增加,对自然环境和人类社会造成了严重危害,因此亟需开发经济高效的废水处理技术。生物电芬顿(BEF)系统是将生物电化学系统与芬顿氧化工艺耦合的水处理技术,其因高效、绿色、节能的特点而受到广泛关注。本文综述了BEF系统的基本原理,讨论了阳极和阴极性能的主要影响因素(微生物胞外电子传递过程、阳极材料、阴极材料、芬顿反应催化剂和系统运行条件),总结了BEF系统在各类废水(染料废水、制药废水、垃圾渗滤液、煤化工废水、养猪废水等)处理中的应用,最后指出BEF系统当前面临的挑战及未来的研究方向,包括开发高效的电极材料和催化剂、耦合其他水处理工艺、降低膜材料成本和开展中试研究等,旨在为BEF系统的进一步发展提供参考。

Abstract:

With the acceleration of industrialization, the types and discharge of wastewater are increasing, which has caused serious harm to the natural environment and human society. Therefore, it is urgent to develop economical and efficient wastewater treatment technology. Bio-electro-Fenton (BEF) system is a water treatment technology which combines bioelectrochemical system with Fenton oxidation process. As a high efficiency, green and energy saving approach, BEF system is attracting a growing interest recently. Here, the work principle of BEF system was introduced. Main factors influencing the properties of anode and cathode were discussed, including the extracellular electron transport process of microorganisms, anode materials, cathode materials, catalysts of Fenton reaction and system operating conditions. The application of BEF system in various wastewater (dye wastewater, pharmaceutical wastewater, landfill leachate, coal chemical wastewater and swine wastewater) treatment was summarized. Finally, the current challenges and future research directions of BEF system were pointed out, including developing the efficient electrode materials and catalysts, coupling with other water treatment processes, reducing the cost of membrane materials and conducting pilot studies, in order to support its further development.

Key words: bio-electro-Fenton system, anode performance, cathode performance, influencing factors, wastewater treatment
