摘　　要：针对某铜矿矿山酸性废水与选矿废水的所形成的混合废水的pH值较低,COD及重金属离子浓度较高的特点,研究利用Fenton氧化-电石乳中和-絮凝联合工艺处理酸碱混合废水的效果,试验表明:联合工艺对废水中的COD和重金属有着较高的去除率,当双氧水、电石乳及PAM投加量分别为340mg/L、12g/L以及2mg/L时,废水经处理后,COD<100mg/L,重金属Zn2+、Cu2+无检出,总铁<0.1mg/L、总锰<0.1mg/L,出水达到国家《污水综合排放标准》(GB8978-1996)一级排放标准。Treatment of wastewater include Acid mine waste water（AMD） and Flotation waste water which was characterized as low pH,high concentrations of metal ions and COD value from a copper mine via Fenton oxidation-neutralization-coagulation（PAM） was investigated.The results show that the treatment processes have higher removal efficiency to the COD and heavy metals.Up to 100% Zn ion and Cu ion removal efficiency were attained.The COD concentrations of the effluent was lower than 100mg/L,and its Fe ion and Mn ion concentrations were lower than 0.1mg/L with using 340mg/L H2O2、12g/L calcium carbide solution and 2mg/L PAM.The effluent quality reaching I-class criteria specified in Integrated Wastewater Discharge Standard（GB 8978-1996）.
