| 摘要: |
| 为得到电Fenton技术深度处理煤化工废水的最优条件参数,采用电Fenton技术深度处理生物稳定的煤化工废水,利用正交试验、响应面法和中心复合试验设计对影响电Fenton处理效果的主要因素进行优化,建立二次模型,并进行试验结果预测．结果表明:各因素对处理效果影响程度的顺序为pH>电流密度>Fe2+浓度．根据方差分析,二次模型具有很高的显著性,能够很好地预测试验结果．影响处理效果的3个主要因素的最优值分别为pH 4.13、Fe2+浓度1.56 mmol／L、电流密度14.74 mA／cm2,此时TOC去除率达61.58％. 电Fenton可以作为煤化工废水深度处理的一种有效技术． |

| Abstract: |
| To obtain the optimal process parameters, the orthogonal test and response surface methodology coupled with central composite design were applied in the optimization of electro-Fenton process as advanced treatment of coal chemical industry wastewater, and a quadratic model was developed to predict the treatment performance. The results showed that the factors affecting TOC removal in descending order was pH, current density and Fe2+ concentration according to the orthogonal test. The developed quadratic model could predict the response accurately, and the optimal parameters were determined as pH 4.3,1.56 mmol／L of Fe2+ and 14.74 mA／cm2 of current density, with the predicted optimal TOC removal efficiency of 61.58％. The electro-Fenton could serve as a effective technology for the advanced treatment of coal chemical industry wastewater. |
