Advances in the enhancement of anaerobic degradation of organic matter by magnetic carbon coupled with microcurrent

厌氧生物技术具有应用范围广、能耗低与资源回收等突出优势,是实现废水有机污染物“减污降碳协同增效”最有效的绿色技术之一,广泛应用于废水处理领域。但传统厌氧技术出水可生化性差,系统易酸化。如何提高厌氧生物技术的高效性及系统稳定性已成为国内外的研究热点。通过国内外文献调研,分别介绍了磁性炭、微电流以及微电流耦合炭材料这3种方式用于强化厌氧生物技术的研究进展,分析了磁性炭及微电流强化厌氧生物降解有机物存在的强化机理以及目前该技术的应用进展,讨论了微电流耦合碳材料构建二维、三维生物电化学系统对强化厌氧生物降解有机污染物的促进作用,并提出了厌氧生物技术今后研究需关注的重点,以期为厌氧生物降解有机污染物的未来研究提供参考。

Anaerobic biotechnology has a wide range of applications,low energy consumption,resource recovery and other outstanding advantages.It is one of the most effective green technologies to achieve the“synergistic effect of pollution reduction and carbon reduction”of organic pollutants in wastewater,which is widely used in the field of wastewater treatment.However,the effluent of traditional anaerobic technology has poor biodegradability and the system is easy to acidify.How to improve the efficiency of anaerobic biotechnology and the system stability becomes a research hotspot at home and abroad.In this paper,the research progress of magnetic carbon,microcurrent and microcurrent-coupled carbon materials for enhancing anaerobic biotechnology was introduced through domestic and international literature research.The promotion of anaerobic biodegradation of organic pollutants by two-and threedimensional bio-electrochemical systems with microcurrent-coupled carbon materials was discussed,and the focus of future research on anaerobic biotechnology was proposed in order to provide reference for future research on anaerobic biodegradation of organic pollutants.
