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 SO^2-₄ 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，SO^2-₄， 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.

Key words: Mine wastewater, Fenton oxidation, Neutralization, Flocculation
