摘　　要：以某钨矿山矿坑废水为治理对象,对中和-絮凝工艺中的NaOH加入量、混凝剂用量、搅拌强度、静置时间等关键因素进行了试验研究。通过治理后废水中的重金属离子含量、pH值分析,处理后废水可达标排放,污泥渣中的重金属可通过后续工艺回收。This paper studies the key elements of neutralization process and flocculation process for treating tungsten mine wastewater, including NaOH adding amount, coagulant dosage, stirring intensity and standing time. Experiments of heavy metals ions contents and PH value determinations show that the treated waste water achieve discharged standards. The heavy metals in the sludge residue can be recovered by the related technology.
