摘要
在控制SBR反应器保持良好的好氧状态条件下 ,考察进水COD/NH3比值对同步硝化反硝化脱氮效率的影响。同时也对同步硝化反硝化机理进行了初步的探讨。研究表明 ,进水COD/NH3比值越高 ,总氮去除率越高 ,同步硝化反硝化现象越明显。由该试验可以推断活性污泥菌胶团中异养硝化菌和好氧反硝化菌的存在。
By controlling the SBR reactor under aerobic condition, investigations were made into the effect of the ratio of influent carbon to nitrogen on nitrogen removal and simultaneous nitrification and denitrification (SND). In addition, the mechanism of SND was explored tentatively. It was found that a higher ratio of influent carbon to nitrogen could produce higher total nitrogen removal efficiency. Conclusion was drawn from the experimental results that there might coexist heterotrophic nitrifiers and aerobic denitrifiers inside the activated sludge flocs.
