| 摘 要： | 将自制的炭气凝胶用作三维电极装置的粒子电极并处理模拟苯酚废水，研究了压缩空气流速、进水pH值、溶液初始浓度及固液比等各种因素对处理结果的影响，发现:炭气凝胶三维电极对苯酚有很好的催化氧化去除效果，去除率最高可达97.5％，浓度可低至4 mg/L，循环50次后，COD去除率仍在80％以上。

| Abstract: | The feasibility of using carbon aerogels (CAs) as bed electrodes in a three dimensional electrode reactor for the electrochemical treatment was studied. It was found that the removal efficiency depended on the airflow, pH, the feed phenol concentration and the ratio of aerogels mass to solution volume. Compared with commercial carbon particle electrodes, the electrodes prepared by CAs exhibited stronger activity to remove phenol simulated wastewater. 97.5% of the initial phenol can be removed after treatment for 20 min, the concentration is as low as 4 mg/L. Moreover, removal efficiency can be kept basically as high as 80% after being reused 50 times. |
