摘要
短程反硝化耦合厌氧氨氧化工艺因曝气量低,节省碳源,脱氮效率高,是近年来备受关注的新型生物脱氮技术。短程反硝化因外加碳源消耗量少,N_(2)O等温室气体排放量低,反应速率高等优点,被认为是最具潜力为厌氧氨氧化提供NO_(2)^(-)底物供给的技术之一。介绍了短程反硝化的反应原理、菌种分类、影响因素及研究进展,分析了厌氧氨氧化的反应原理、菌种分类、影响因素、研究进展,总结了短程反硝化耦合厌氧氨氧化工艺的研究进展,展望了耦合工艺在废水脱氮处理工程的应用前景,认为优化短程反硝化各项反应控制参数、探究耦合工艺脱氮机理以及生物载体的附着作用是未来耦合工艺脱氮处理被推广应用的重点研究方向。
Shortcut denitrification coupled with anammox is a new type of biological denitrification technology which has attracted much attention in recent years due to low aeration,carbon source-saving,and high denitrification efficiency.Shortcut denitrification is considered to be one of the most potential technologies to provide NO_(2)^(-) substrate for anammox due to its advantages of less consumption of external carbon source,low emission of greenhouse gas such as N_(2)O,and high reaction rate.The reaction principle,bacterial classification,influencing factors and research progress of shortcut denitrification coupled with anammox were introduced,the application prospect of the coupling process in wastewater denitrification treatment project was expected.It was considered that optimizing the control parameters of shortcut denitrification reactions,studying the denitrification mechanism and the adhesion of biological carrier of the coupling process were the key research directions for the popularization and application of the coupling process denitrification treatment in the future.
