ABSTRACT
For mine wastewater and mine tailings wastewater from copper mine concentrator, considering the characteristics and economic utilities of the physical treatment, chemical treatment, physical chemistry treatment and biological treatment, the mixed wastewater after reaction was neutralized and coagulated by using aluminium chlorohydrate iron as flocculant, and the flocculating properties of poly aluminium chloride and polyacrylamide were compared to achieve the function of treating the wastewater. The results show that the combined treatment technology of the first stage neutralizing, second stage neutralizing, poly aluminium chloride coagulation reaction, polyacrylamide flocculation reaction should be selected so as to make the effluent water quality meet the standard of reuse or discharge and the natural sedimentation has a good effect on the removal of suspended solids in wastewater.
