摘　　要：针对酸性矿井水高铁、CODCr和SS浓度高的特点,设计采用石灰中和-曝气反应-预沉调节-机械混合-机械絮凝-斜管沉淀-普通快滤池-紫外线-次氯酸钠联合消毒的处理工艺,介绍了该工艺流程、设计参数及工艺特点。工程运行结果表明,出水水质满足GB 3838—2002《地表水环境质量标准》Ⅳ类标准和回用要求。In view of the fact that acid mine wastewater contains high concentration of iron, CODCr and SS, a combined disinfection process of lime neutralization-aeration reaction-pre sedimentation adjustment-mechani-cal flocculation-inclined tube sedimentation-common rapid filter-ultraviolet light-sodium hypochlorite was de-signed. The flow, design parameters and characteristics of the process were introduced. The project running re-sults showed that, the effluent water quality met the requirements of both grade 郁 in GB 3838-2002 Environ-mental Quality Standards for Surface Water and reuse.
