| 摘 要： | 采用批次实验的方法探讨了3种不同温度（15℃，25℃，35℃）对亚硝化及其过程中温室气体氧化亚氮释放情况。结果表明，温度对亚硝化过程及氧化亚氮的释放有显著影响。在15～35℃范围内，随着温度的升高，氨氧化率和亚硝化积累率逐渐升高，N2O释放量也逐渐增大，35℃可以作为适宜的亚硝化温度，平均氨氧化率为50．9％，亚硝化积累率为55．6％，NO-2-N与Nrl4-N出水浓度比为1．1，氨氧化率，亚硝化积累率和出水中亚硝氮与氨氮浓度比较合适，从而可以为厌氧氨氧化工艺提供合适的进水，但在此温度下平均N2O释放量相对较高，为1．494la,g／gMLSS。

| Abstract: | To investigate the effect of temperature on partial nitrification and nitrous oxide emission in the process, batch experiments at different temperatures（ 15℃ ,25℃ ,35℃ ） were conducted. The results indicated that temperature has important effect on partial nitrification and nitrous oxide emission in the process. In the range of 15 to 35℃ , ammoxidation percentage, nitrite accumulation rate and the emission of nitrous oxide rose with the temperature going up. 35~C is the appropriate temperature for partial nitrification, the reason is that the average ammoxidation percentage is 50.9% , the nitrite accumulation rate is 55.6% and the ratio of NO2--N to NI-I4 -N is 1.1 at this temperature. The ammoxidation percentage and the ratio of NO2- -N to NH4 -N at 35℃ were appropriate, so the partial nitrification can supply proper inflow to anaerobic ammonium oxidation. The average emission of N2O is higher which is 1. 494 μ/g MLSS. |
