Abstract:

According to the characteristics of the drainage water from a lead-zinc mine tailing pond, Fenton process and coagulation-sedimentation method are used to treat the wastewater. After treatment, the effluent can meet the first grade standard of Comprehensive Wastewater Discharge Standard(GB 8978-1996) and Emission Standard of Pollutants for Lead and Zinc Industry(GB 25466-2010). The treatment process has stable operation and high impact resistance.

Key words: lead-zinc mine, external drainage of tailings pond, Fenton, coagulation

摘要：

针对某铅锌矿尾矿库外排水水质特点，采用Fenton工艺及混凝沉淀法对该废水进行处理。废水经处理后，出水可达到《污水综合排放标准》（GB 8978—1996）一级标准要求、《铅锌行业污染物排放标准》（GB 25466—2010）要求。处理工艺运行稳定，耐冲击能力强。
