厌氧氨氧化技术的研究进展

Research progress of anaerobic ammonia oxidation technology

“双碳”背景下,污水处理不仅要对污染物进行削减,更重要的是降低污水处理过程的能耗,减少碳排放。厌氧氨氧化技术溶解氧需求低,不需要有机碳源,作为低碳的生物脱氮新型工艺得到普遍认可和关注。介绍厌氧氨氧化的发展历程、反应机理和影响因素,结合厌氧氨氧化工艺应用现状和效果分析,对该技术的应用前景进行展望,为后续技术的应用和推广提供参考。

Under the background of‘dual carbon',sewage treatment should not only reduce pollutants,but more importantly,reduce the energy consumption of the sewage treatment process and reduce carbon emissions.Anaerobic ammonia oxidation technology has low demand for dissolved oxygen and does not require organic carbon sources.As a new low-carbon biological denitrification process,it has been widely recognized and concerned.The paper introduces the development process,reaction mechanism and influencing factors of anaerobic ammonia oxidation in detail.Combined with the application status and effect analysis of anaerobic ammonia oxidation process,the application prospect of this technology is prospected,which provides reference for the application and promotion of subsequent technologies.
