摘要(Abstract)：

为了准确模拟预测污水生物脱氮过程反硝化阶段一氧化二氮N₂O的产量，实现污水处理过程中N₂O减排精准控制，在充分结合传统反硝化理论与反硝化阶段微生物衰减导致N₂O产生的理论假设的基础上，运用活性污泥3号模型(ASM3),构建污水生物脱氮过程反硝化阶段N₂O生成动力学模型，运用MATLAB软件建立N₂O生成动力学模型初值计算、灵敏度分析的程序计算方法，拟合分析N₂O生成动力学模型理论预测数据与序批式活性污泥反应器实验数据。结果表明，所构建的反硝化阶段N₂O生成动力学模型对污泥反应器化学需氧量、亚硝态氮(NO₂^--N)、硝态氮(NO₃^--N)、 N₂O等组分含量的模拟预测效果良好，决定系数R²分别为0.953、 0.925、 0.996和0.878。
