活性碳—天然锰砂混合处理镀锌废水的初探

Treatment of zinc plating wastewater by the mixture of activated carbon and nautural maganess oxide

介绍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 实验结果表明废水鼓氧 (曝气 )通过活性炭 :天然锰砂 =2∶3滤材过滤后 ,Zn2 + 的去除率达 95 1 % ,Fe3 + 的去除率达99 6 % 废水 pH值上升到 6 0 。

The treatment process of the Zine planting wastewater by the mixture of activated carbon and nautural manganese oxide is introduced. The experiments show that the cleansen proportion of Zn 2+ is 95.1%, that of Fe 3+ is 99.6%, the caidity of wastewater arrives at pH=6 and the treated wastewater meets the need of national standard.
