摘要
介绍了锰氧化菌介导生物脱氮的作用机制及其在污水脱氮中的应用;阐述了该菌通过催化锰氧化还原反应直接转化氮素的过程,及其生物氧化锰产物提升有机物分解与碳源利用率的协同作用;归纳了pH、温度、溶解氧和共存离子对菌体代谢与酶活性的调控规律;分析了该技术在地下水修复、工业/生活污水处理中的工程优势;指出规模化应用需突破Mn(Ⅲ)稳定性不足引发电子传递效率波动、低温(<5℃)菌群活性衰减、高成本菌剂制备及多工艺耦合互作机制不明等瓶颈。
This paper introduces the mechanism of manganese-oxidizing bacteria-mediated biological nitrogen removal and its application in wastewater denitrification.It elaborates on the process by which these bacteria directly convert nitrogen by catalyzing manganese redox reactions and the synergistic effect of biologically oxidized manganese products on enhancing organic matter decomposition and carbon source utilization.It summarizes the regulatory patterns of pH,temperature,dissolved oxygen,and coexisting ions on the metabolic and enzymatic activities of bacteria.It also analyzes the engineering advantages of this technology for groundwater remediation and industrial and domestic wastewater treatment.It is pointed out that the large-scale application needs to break through the bottlenecks such as the fluctuation of electron transfer efficiency caused by the insufficient stability of Mn(Ⅲ),the attenuation of bacterial community activity at low temperatures(<5℃),the preparation of high-cost bacterial agents,and the unclear mechanism of multi-process coupling and interaction.
