建立了新型的以厌氧消化1号模型为基础的对流扩散模型来模拟升流式厌氧污泥床反应器，在此模型中同时考虑了水动力学及生化动力学。模型涉及的偏微分方程借助中心有限差分法在M atlab中编程进行求解。示踪剂实验与两组有机负荷冲击实验分别用于验证对流扩散模型的水动力学及生化动力学，结果显示模拟数据与实验数据能很好地吻合。此外，所建立的模型还能反映不同高度处的反应器状态，借助这个优势可以在反应器遭受异常情况时进行预警。

A novel Anaerobic Digestion Model No .1 based dispersive model was developed to simulate the upflow anaerobic sludge blanket reactor (UASB) ,in which both hydrodynamics and bio-dynamics were taken into account .The partial differential equations in the model was solved by finite difference method in Matlab . A tracer study and two loading-shock experiments were used to validate the reactor's hydrodynamics and bio-dynamics ,respectively .The simulated data match the experimental data very well . Besides ,the developed model can reflect the reactor's status at different heights ,w hich makes it possible to give early warnings in abnormal situations .
