摘要:
焦化废水具有高浓度、成分复杂、生物毒性高等特点,采用常规处理方式处理焦化废水具有很大的挑战性。与传统生物法、电化学相比,生物电化学系统(Bioelectrochemical System, BES)不仅具有同时去除焦化废水中碳质和氮质污染物的能力,而且可以通过电强化微生物的协同作用,节省整个处理过程的能量消耗。但是,鲜有综述对生物电化学系统在处理焦化废水中的研究进行系统总结。因此,文章在回顾BES原理、类型、电极材料的基础上,总结了BES在焦化废水处理中的研究进展,并分析了其在去除有机污染物、氨氮等污染物方面的强化效果。通过这些系统的回顾,本综述不仅阐述了电强化微生物促进焦化废水中污染物的作用机理,提出了未来关于BES的研究方向,还展望了BES用于焦化废水处理的前景和挑战,从而促进了BES在焦化废水处理中的实际应用。Coking wastewater is characterized by high concentrations, complex composition, and high biological toxicity, making its treatment challenging using conventional methods. Compared to traditional biological and electrochemical processes, the Bioelectrochemical System (BES) not only have the capability to simultaneously remove carbon and nitrogen pollutants from coking wastewater but also enhance microbial activity through electrical stimulation, thereby reducing energy consumption in the treatment process. However, there is a lack of systematic reviews summarizing the research on BES in coking wastewater treatment. This paper reviews the principles, types, and electrode materials of BES, summarizes the research progress of BES in coking wastewater treatment, and analyzes its enhanced effects in removing organic pollutants and ammonia nitrogen. Through this systematic review, the mechanisms by which electrostimulation promotes pollutant removal in coking wastewater are elucidated, future research directions for BES are proposed, and the prospects and challenges of using BES for coking wastewater treatment are discussed, thereby facilitating the practical application of BES in this field.
