摘　　要：概述了有色金属矿山酸性废水来源、特点和现有处理技术,重点介绍了几种常用和有应用前景的处理工艺;通过分析比较,筛选出高密度石灰法(HDS)作为废水处理达标排放的较佳工艺,生物法(硫化还原和氧化处理)与铁屑置换作为回收有价金属并使废水回用的较佳工艺,为企业选用提供科学依据。In this paper, the source,characteristics and the existing disposal methods of nonferrous metal mines are summarized, and several common used and prospective disposal methods are introduced as an emphases. Through analysis and comparison, the HDS is selected as a preferable method for the wastewater for standard-reaching emission, and the biological method （sulfurate deoxidization and oxidization） and the metathesis of iron crumbs are selected to reclaim valuable metal from wastewater. The study can provide a scientific reference for enterprises to choose methods.
