| 摘 要： | 采用催化铁内电解法,在曝气和无曝气条件下,对有机废水的处理效果进行了比较并且分析了在不同条件下的反应机理。结果表明,若不考虑反色现象,无曝气条件下对色度的去除率达到88%,高于曝气条件下的去除率69%,在无曝气条件下色度的去除主要是由于染料分子被还原,而曝气条件下色度的去除主要是由于铁离子的絮凝作用;对于COD的去除率,曝气条件下为41%,高于无曝气条件下的22%。

| Abstract: | Using catalyzed iron internal electrolysis to treat organic wastewater under aeration and anaerobic conditions,the treatment effects were compared with the mechanisms of the reactions under different conditions analyzed.The results showed that,the removal rate of colority reached 88% under anaerobic condition without consideration of color restoration,higher than 69% under anaerobic condition.Dye molecule's reduction played an important role in the course of color removal under anaerobic condition,while,the flocculation effect of iron ion was the most important factor caused the color removal under aeration condition;The removal rate of COD reached 41% under aeration condition,higher than 22% under anaerobic condition. |
