活性炭和天然锰砂混合处理镀锌废水的研究

Treatment of Zinc Plating Wastewater by the Mixture of Activated Carbon and Nautural Maganese Oxide

介绍用活性炭和天然锰砂作反应剂交互作用处理镀锌废水的研究 .实验结果表明 :活性炭 :天然锰砂 =2 :3 ,加以鼓氧 ,静置后过滤 ,废水处理效果更好 .Zn2 + 的去除率达 99.8% ,Fe3 + 的去除率达 99.6% ,废水pH值上升到 6.0 .达到国家废水排放标准 .

This paper describe the treatment process of a Zine plating waste water by the mixture of activated carbon and natural manganese oxide. The experiments show that the cleanser proportion of Zn 2+ is 99.8%, the cleanser proportion of Fe 3+ is 99.65%,the acidity of wastewater arrives at pH 6 and the treated wastewater meets the need of the national standard.
