摘要
以ASM3原理为基础,引入污染物迁移方程,并加入位移变量,建立了基于ASM3的改进活性污泥模型模拟系统。以序批式呼吸计量试验对ASM3中异养菌好氧产率系数YH,O2、异养菌好氧内源呼吸速率系数bH,O2、异养菌的最大比生长速率μH和自养菌的最大比生长速率μA等4个重要的模型参数进行了确定,其它参数采用IWA推荐的典型值对工艺试验进行模拟。通过对COD,NH4+-N以及NO3--N进行模拟,模拟结果和实测结果吻合较好。
An improved activated sludge model simulated system which is based on ASM3 by introducing the pollutant transport equation and the displacement variable as well into the model was established. This paper determined the values of YH1O2, bH1O2,μHs μA which are more important model parameters in batching respiration experiment. Running the modeling program with the other default parameters, the modeling and simulating results suggested that there was a good agreement between the modeling values and the practical measured values.
