| 摘 要： | 水体锌污染危害严重。对三维电极处理Zn2+浓度为95·0mg/L模拟废水进行了试验研究,并通过正交试验得到了三维电极处理模拟含锌废水的最佳运行条件。结果表明,电解时间、主电极间距、粒子电极活性碳与处理水量的比例及电解电流等对三维电极处理废水的效率有显著影响,在最佳条件下,三维电极对模拟废水Zn2+去除率达到95·7%,可使废水中Zn2+浓度降低到4·1mg/L,满足国家污水综合排放标准GB8978-88Ⅱ级要求。

| Abstract: | Zinc pollution in water is very serious.Three Dimensional Electrode (TDE) is used to treat analogue wastewater with 95.0mg/L Zn~ 2+ .Orthogonal experiment is done to get the optimal condition of TDE to treat zinc-containing wastewater.The result shows that electrolytic time,main electrode distance,the percentage of activated charcoal and the amount of treated wastewater,electrolytic current have salient effect on the removal efficiency.Under the optimal condition,Zn~ 2+ removal ratio is as high as 95.7%,the concentration of Zn~ 2+ reduces to 4.1mg/L,which meet the national discharge standard GB 8978-88. |
