A2N ( anaerobic/ anoxic/ nitrifying) denitrifying phosphorus and nitrogen removal process is a new process developed based on the theory of phosphorus uptake by denitrifying phosphorus accumulating organisms under anoxic condition.
A2N（厌氧/缺氧和硝化）反硝化除磷脱氮工艺是基于反硝化聚磷菌缺氧吸磷理论开发的新工艺。
The inherent shortcomings of A 2/ O process, thereinto the contrary competition of nitrifying bacteria, denitrifying bacteria and polyphosphate accumulating organisms for organic loading, sludge age and carbon sources impeded the promotion of their application for N and P removal.
分析了A2/O系统的固有缺欠：硝化菌、反硝化菌和聚磷菌在有机负荷、泥龄以及碳源需求上存在着矛盾和竞争，阻碍着生物除磷脱氮技术的应用。
In the denitrifying nitrogen and phosphorus removal system, the biological nitrogen removal and phosphorus removal are the two independent and overlapped processes, and there exists competition for different sludge ages of nitrifying bacteria and phosphorus accumulation organisms ( PAOs).
反硝化除磷脱氮系统中，生物脱氮与生物除磷是两个相互独立、相互竞争又相互交叉的生理反应过程，存在着硝化菌与聚磷菌的不同泥龄之争。
