Abstract

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
