| 摘 要： | 以颗粒污泥为研究对象,在序批式反应器中研究了不同运行模式(有厌氧段和无厌氧段两种模式)和不同碳氮比(COD与NH4+-N质量比取6、10、14)下,颗粒污泥对氨氮、总无机氮的去除情况.比较了2种运行模式应用于颗粒污泥脱氮中的差别和优劣.采用分段函数的方法对不同碳氮比下的氨氮去除曲线进行了分割,对曝气第一阶段(碳源富足阶段)和曝气第二阶段(碳源贫乏阶段)的氨氮去除曲线进行了拟合,发现其线性化特征明显.计算了不同碳氮比下曝气前后期氨氮去除速率,并简要分析了好氧颗粒污泥同步硝化反硝化脱氮的作用机理.

| Abstract: | The removal efficiency of ammonium and total inorganic nitrogen (TIN) were studied in an aerobic granular sludge SBR system under different running modes (with and without anaerobic phase), and different C/N ratio (COD/NH4 -N) at 6, 10, 14. The inference advantages and disadvantages for nitrogen removal running in these two modes were also compared. The NH4 -N removal curve in different C/N ratios were divided adopting divided phase function technique; and the removal curves of the first (carbon source abundant) and the second (carbon source feast) phases were simulated, and their character of linearity was found. The ammonium nitrogen removal rates before and after these phases were calculated, and the mechanism of simultaneous nitrification and denitrification in aerobic granular sludge system was analyzed briefly. |
