摘　　要：矿山酸性废水酸度高、污染物种类多,碱性废水碱性高、浮选药剂残留造成 COD 浓度高、波动大,常规方法处理难度大。采用酸碱性废水混合处理的方法,实现酸碱中和,达到以废治废的目的;铁离子和与 S离子发生化学反应,降低了废水 COD 浓度;铁离子的凝聚作用,加速了固液分离效率。混合后再采用深度氧化工艺处理后,出水 COD 指标稳定低于《铜、镍、钴工业污染物排放标准》(GB 25467-2010)要求的排放值,该工艺抗冲击负荷强,净化效率高,工艺稳定。It is difficult to treat mining wastewater due to high acidity & various types of pollutant of acid wastewater and high alkaline & COD concentration of alkali wastewater. The co-treatment of acid and alkali wastewater has following advantages: acid-base neutralization reaction achieving the purpose of waste treatment waste, iron ion and Sion reaction reducing COD concentration, the coagulation of iron ions accelerating efficiency of solid-liquid separation. Advanced oxidation treatmeng after co-treatment satisfies emission standard of 60 mg/L in this industry. The treatment process has characteristics of powerful resistance to impact load, high purification efficiency and stable operation.
