| 摘 要： | 磁粉活性污泥法是在传统活性污泥法中加入磁性粉末(Fe3O4)的废水生物处理方法。在最佳运行状况下,对磁粉活性污泥法基质降解动力学进行了研究。磁粉活性污泥法基质降解符合一级反应规律,利用Monod方程对试验数据进行拟合,确定了其动力学参数,半速率常数Ks、有机底物的最大比降解速率vmax分别为10.39 mg/L和0.804 d-1。

| Abstract: | The magnetic activated sludge process is a modification of the conventional activated sludge process,which is supplemented with ferromagnetic powder(Fe3O4) to create a magnetic activated sludge.The kinetics of the magnetic degradation is analyzed for the process of municipal domestic sewage treatment by powder activated sludge under the best operating condition.The matrix degradation of magnetic activated sludge is consistent with 1st-order reaction equation.The experiments results are fitted with the Monod equation,and the parameters Ks and vmax should be 10.39 mg/L and 0.804 d-1 respectively. |
