【摘要】 矿山酸性废水(AMD)中含有多种重金属离子,未经处理直接排放会对矿山周边生态环境及水环境造成严重污染,是我国南方地区有色金属矿山在生产经营活动中存在的主要环境问题。本次试验研究采用HDS工艺及树脂吸附法联合对南方某锡矿山AMD进行处理,试验结果表明HDS工艺及树脂吸附法深度处理矿山酸性废水可有效去除AMD中的各类污染物,经HDS工艺预处理后的废水可以达到排放标准要求,再经树脂吸附法处理后废水中的砷、镉可以达到《地表水环境质量标准》中Ⅲ类水体标准要求。更多还原

【Abstract】 Acid mine discharge(AMD) contains a variety of heavy metal ions.The untreated discharge will cause serious pollution to the ecological system and water bodies,which is a major environmental issues induced by nonferrous metal mining activities in southern China.This study employs HDS process in conjunction with resin adsorption for the treatment of AMD from a Tin Mine located in southern China.The test results indicate that the advanced treatment of AMD by using HDS process with resin adsorption can effectively remove various pollutants in AMD.The treated wastewater after HDS process meets the effluent standards.The concentration of typical heavy metals such as arsenic and cadmium in the wastewater reduced further more in resin adsorption process,which meet the standards required for class Ⅲ surface water environmental quality standards.更多还原
