| 摘 要： | 文章研究溶解氧及活性污泥浓度对同步硝化反硝化效率的影响。研究结果表明：在一定DO范围内，随着反应器内溶解氧浓度的降低，总氮去除率呈上升趋势，即好氧反硝化效率随溶解氧浓度的降低而提高；在一定MLSS范围内，反应器内混合液污泥浓度越高，出水总氮越低，反硝化现象越明显。

| Abstract: | In this paper, the effect of DO concentration and MLSS on simultaneous nitrification and denitrification was studied. Results showed that, to some extent, total nitrogen removal efficiency had a tendency to rise with the decrease of DO concentration in the reactor. The lower the DO concentration, the higher the efficiency of aerobic denitrification. Total nitrogen concentration in the effluent decreased with the increase of MLSS, leading to a more apparent denitrification efficiency. |
