| 摘 要： | 在Monod方程的基础上推导了适用于描述工业废水的生化耗氧过程Logistic动力学模型,比较了Logistic动力学模型和一级动力学模型的区别。测定了废水的BOD5/CODcr,在此基础上对可生化废水的生化耗氧曲线进行分析,利用Logistic动力学模型对生化耗氧过程进行动力学研究,并比较各种不同稀释倍数时的kLog和S0。研究结果表明:随着稀释比的增大,耗氧过程的动力学参数kLog和计量系数S0增大,且S0和废水的BOD5非常接近。

| Abstract: | The article educes logistic kinetic model that fits to describe the biochemical oxygen-consumed process of industrial wastewater and compares the difference between logistic kinetic model and the first-order kinetic model. The ratio of BOD5/CODcr of the wastewater is determined and then the biochemical oxygen-consumed curve is analyzed. It studies the oxygen-consumed process with logistic model and compares Klog and S0 under different dilution rates. The results demonstrate that Klog and S0 increase, and S0 is adjacent to BOD5 with the increase of the dilution rate. |
