摘　　要：为解决某铅锌矿选矿废水循环利用的问题,重点对自然降解、混凝沉降、混凝沉降-活性炭吸附及Na2SO3处理等方法,分别进行了回用方案的试验研究。其中,混凝沉降-活性炭吸附处理,可有效去除废水中的重金属离子及有机污染物,处理后的选矿废水回用作选矿用水,不会对选矿指标造成不利影响,可实现选矿厂废水的零排放。Experiments of autogenous sedimentation, coagulating sedimentation and activated-carbon adsorbing separation etc. disposed mining wastewater were conducted in order to reuse mining wastewater. The results showed that CODer and heavy metal ion of wastewater could be removed effectively by coagulating sedimentation-activated carbon adsorbing separation; the disposed wastewater could be discharged di-rectly or reused to mineral concentration without influencing mineral concentration process. The zero discharge of mineral concentration wastewater could be realized.
