| 摘 要： | 自养菌生长动力学参数(μA)是污水处理系统模拟和设计的关键参数,该值对污水特性非常敏感,需要准确测定.通过连续监测恒温间歇反应器中硝态氮浓度的变化,并结合非线性最小二乘法进行拟合,给出了μA的测定方法.在不同污泥浓度下多次试验的测定结果表明,该方法具有较好的重现性,试验测定μA的最佳VSS为100～200 mg/L.对上海市曲阳水质净化厂的测定结果表明,20℃时好氧池中自养菌的μA为(0.79±0.06)d-1;温度对μA的影响显著,其Arrhe-nius温度系数约为1.11.

| Abstract: | The maximum specific growth rate of autotrophic bacteria is crucial for modeling and designing the nitrification process in wastewater treatment systems.Because the nitrification process is so sensitive to this value,its measurements should be precise and accurate.Through continuously monitoring nitrate nitrogen concentration in the batch reactors,the growth rate of autotrophic bacteria was calculated by the non-linear least squares method.The test results demonstrate that this method,used for different slu... |
