| 中文摘要: |
| 在单因素试验基础上，采用Box Behnken响应面法对旋转式电芬顿装置去除垃圾渗滤液中COD的运行条件进行优化。结果表明：响应面法拟合得到的最佳运行条件为外接电压936 V，电极搅拌速率11973r/min，电极有效接触面积891cm2，预测COD的去除率为6856%；在此最佳条件下，用旋转式电芬顿装置处理6 L实际水样，得到COD去除率为6983%，实测值与预测值绝对误差为127%，两者吻合度较好。 |

| On the basis of single factor experiment，the operating conditions of rotary electric Fenton device for removing COD from landfill leachate was optimized by Box Behnken response surface method．The optimal operating conditions obtained by response surface fitting were that the external voltage was 9.36 V， the electrode stirring rate was 119.73 r/min， the effective contact area of electrode was 89.1 cm2， and the predicted COD removal rate was 68.56%. Under these optimal conditions， using rotary electric Fenton device to treat 6 L of actual water samples， the removal rate of COD was 69.83%， and the absolute error between measured and predicted values was 1.27%， indicating a good agreement between them. |
