| 摘 要： | 实验对恒液位SBR工艺脱氮除磷进行了研究。结果表明,交替缺氧/好氧段,可以有效的实现硝化反硝化脱氮和好氧摄磷,缺氧时,进水补充的碳源及时满足了反硝化的需求,系统同时还存在同步硝化反硝化作用。厌氧段,溶解氧快速降至0mg/L在进水补充的碳源条件下释磷充分,从而保证后期摄磷完全,整体高效脱氮除磷。

| Abstract: | Mechanism of removing nitrogen and phosphorus by level-constant SBR was studied. Results indicated that when the system was in alternate anoxic/oxic, nitrification and denitrification were achieved and phosphorus was absorbed. In anoxic, the carbon source supplied by influent accelerated denitrification, with simultaneous nitration and denitrification. In anaerobic, DO reduced to 0mg/L quickly with carbon source supplied by influent water phosphorus released completely to ensure phosphorus be absorbed completely. |
