| 摘 要： | 针对中等含氮废水的处理进行了SBR法脱氮的研究.试验结果表明:在COD/N为5.5~7,溶解氧为2.5 mg/L时系统处于最佳运行状态.亚硝化状态与温度的变化表现出了一定的相关性.在反应器中存在着复杂的脱氮途径,实现了亚硝酸型同步硝化反硝化(SND)工艺,并且存在明显的好氧反硝化菌的脱氮作用.

| Abstract: | This paper studied the ability of SBR(Sequencing Batch Reactor) process to removal nitrogen.It is running best that under the experimental condition of the COD/N 5.5-7 and DO 2.5 mg/L.The state of the short-cut nitrification is pertinence with the temperature.The results showed that the approach of the nitrogen removal is the short-cut nitrification and the simultaneous nitrification-denitrification. |

| Keywords: | SBR system Short-cut nitrification simultaneous nitrification-denitrification aerobic denitrification |
