- 摘要：对Anammox-DAMO系统、Nitrite-DAMO系统、Nitrate-DAMO系统进行基质降解动力学研究，建立了3个DAMO系统温度耦合模型，并对建立的温度耦合模型进行拟合分析.结果表明，二级基质降解动力学能更好地描述Anammox-DAMO系统脱氮动力学行为，半级基质降解动力学能更好地描述Nitrite-DAMO系统和Nitrate-DAMO系统脱氮动力学过程.在15~50 ℃条件下，3个系统脱氮效率均在35 ℃时达到最高，对脱氮动力学的评估表明，3个系统反应动力学均符合Arrhenius方程.根据动力学模拟得出，Anammox-DAMO系统受高温影响更明显，而另外两个 系统则受低温影响更明显.
- Abstract：The substrate degradation kinetics of Anammox-DAMO system， Nitrite-DAMO system and Nitrate-DAMO system were studied. The temperature coupling models of the three DAMO systems were established and were analyzed by fitting them to measured data. The results showed that the second-order substrate degradation kinetics could better describe the denitrification kinetic process of Anammox-DAMO system， while the half-order substrate degradation kinetics could better describe the denitrification kinetic process of Nitrite-DAMO system and Nitrate-DAMO system. Between 15~50 ℃， the denitrification efficiency of the three systems reached the highest at 35 ℃. The evaluation of denitrification kinetics showed that the reaction kinetics of the three systems accorded with Arrhenius equation. According to the dynamic simulation， Anammox-DAMO system was more affected by high temperature， while the other two systems were more affected by low temperature.
