在活性碳与铁屑组成的腐蚀体系中添加氧催化剂 Mn O2 ,并进行曝气形成催化铁 -氧腐蚀电池 .使用这种催化铁 -氧腐蚀电池对活性艳红 X- 3B模拟染料废水进行了处理 ,并研究了若干因素对其处理效果的影响 .结果表明 ,该法比普通铁屑处理法效果大有提高 ,处理 10 m in脱色率就可达到 98%以上 ,COD去除率高达 82 % (一般在 70 %～ 80 %之间 ) ,最佳处理效果时的 p H=7,不需要另调 p H,对处理条件要求宽松 ,应用前景广泛 . In the corrosion system composed of activated carbon and iron filings, oxygen catalyst Mn O2 was added and aerated to form catalytic iron-oxygen corrosion cell.Using this catalytic iron-oxygen corrosion cell, Reactive Red X-3B simulated dye wastewater was The results show that the method has much better effect than ordinary iron filings treatment, the decolorization rate of 10 m in can reach more than 98%, COD removal rate is up to 82% Generally between 70% and 80%), p H = 7 at the best treatment effect, no need to be adjusted p H, and the treatment conditions are relaxed and the application prospect is wide.
