摘　　要：针对铜钨矿开采过程中产生含砷废水的生产实际,结合含砷废水处理方法以及本工程废水中所含污染物的实际情况,通过采用预氧化/混凝沉淀/多介质过滤组合工艺对本工程废水进行处理,处理后出水含砷量为0.04 mg/L,低于《地表水环境质量标准》(GB 3838-2002)中Ⅲ类水体中砷的限值(0.05 mg/L),为同类型废水处理提供了工程借鉴。Aiming at the actual production of arsenic-containing wastewater generated during the mining of copper and tungsten ore, combined with the treatment method of arsenic-containing wastewater and the actual situation of the pollutants contained in the wastewater of this project, the combined process of pre-oxidation/coagulation sedimentation/multi-media filtration is adopted The wastewater of this project is treated, and the arsenic content of the effluent after treatment is 0.04 mg/L, which is lower than the limit of arsenic in Class Ⅲ water bodies(0.05 mg/L) in the Environmental Quality Standard for Surface Water(GB 3838-2002). The same type of wastewater treatment provides engineering reference.
