厌氧反应器停留时间分布测定及流动模型研究

Study on measurement of residence time distribution and flow model for anaerobic reactor

应用脉冲输入法对厌氧反应器进行了冷模试验,测定了电导率随时间的变化关系,建立了一个PFR串联两个并联的CSTR的三参数流动模型,依据实验数据计算了模型参数,获得了E(t)-t方程,并与实验值进行了比较,证明两者具有较好的拟合度。

The pulse inputting method is applied to test of the anaerobic reactors in cold condition, which determines the changes of conductivity with time. A three parameters model including a PFR series and two parallel CSTR is set up. Based on experimental data, we calculate the model parameters and acquire E （t）-t equation, which is compared with the experimental values. The results show that they have good fitting degree.
