摘要
以德兴铜矿工业废水处理站矿山废水为研究对象,以COD、重金属离子、SO24-以及SS作为出水水质考察指标,研究采用Fenton氧化—中和—PAM絮凝工艺实现废水达标排放的可行性。48 h的工业试验结果表明,H2O2、电石乳以及PAM的合理投加,可以实现COD、SO24-及重金属阳离子、SS的高去除率,使出水的各项指标均符合《GB8978—1996污水综合排放标准》的一级标准。
Taking the mine wastewater from the industrial waste-water treatment station of Dexing Copper Mine as research target,and the index of Chemical Oxygen Demand（COD）,heavy metals ion and SO2-4 and suspended solid（SS） as water quality monitoring index,the feasibility of applying the integrated Fenton oxidation-neutralization-PAM flocculation techniques to attain standard discharge is studied.The industrial experiments for 48 h indicated that with the rational addition of H2O2,calcium carbide and PAM,a high removal rate of COD,SO2-4,the heavy metal ion and SS was realized.Then each index of the treated water can meet I-class criteria specified in Integrated Wastewater Discharge Standard（GB 8978-1996） in China.
