摘　　要：对常用工艺进行比选,采用石灰-亚铁絮凝共沉淀法处理镍钼矿冶炼废水。针对该废水的特点,设计了一套污水处理工艺流程。工程实际运行结果表明,废水经该工艺流程处理后,砷、镍等主要污染物去除率可达99%以上,出水水质可达到《污水综合排放标准》(GB8978-1996)中的一级标准。该工艺运行稳定,操作简便,处理效率高,出水水质好。Using the lime-ferrous flocculating precipitation to treat wastewater of nickel-molybdenum minerals by comparison of conventional process,a sewage treatment process is designed for the characteristics of wastewater.Engineering operation shows that removal efficiency of arsenic,nickel and other major pollutant are above 99%.After wastewater treated by the process,the effluent quality can achieve the primary standard of＂Integrated Wastewater Discharge Standard＂（GB8978-1996）.The treatment efficiency of the process is high and stable,the operation is easy and simple,and the water quality is good.
