摘要
依据物料平衡方程和Fick定律,结合活性污泥-生物膜复合工艺的实际情况,建立了一个可指导实际工程设计的简单硝化动力学模型,并通过实验室试验和生产性试验对模型进行了验证。验证结果表明理论值和实测值符合的很好,模型能够较好地预测系统出水的氨氮浓度,且适合工程实际计算。
A simplified kinetic model is proposedto describe the nitrification in the hybrid bio-reactor. The model is derived based on mass balance expressions, the Fickian diffusion law, and the operational conditions of the reactor. The application of the model in both lab-scale and full scale experiments indicated that the theoretical values and the practically values were well in conformiy with each other, thus, the model is suitable for the project design.
