摘要

有色金属尾矿库常呈现典型区域性分布特征,一旦发生事故对水环境危害严重。目前国内外研究多以单一水体污染程度作为衡量指标,评价指标未能全面反映水环境风险。本文以典型多金属伴生矿区为研究对象,对比水质质量指数法、内梅罗综合污染指数法、密切值评价法、污染负荷指数法,从地表水和底泥的单因子和多因子综合污染影响分析,并采用基于SQG-Q的沉积物重金属污染风险评估,以便更为科学、全面、准确客观地评估区域内多座尾矿库对下游水体的环境风险。为后续有色金属尾矿库开展系统的水环境风险评估方法研究打下基础。
        Tailings ponds for non-ferrous metals often exhibit the regional distribution characteristics,once accident of tailings pond occurs,aquatic environment will be seriously attacked.Present studies focus on simplified single-indicator approach,which are failed to fully reflect the aquatic environmental risk.In this present study,polymetallic mine was studied by comparing the methods in water quality index,Nemerow pollution index,Osculating value evaluation and pollution load index.Environmental impact of comprehensive pollution in singlefactor and multi-factor of surface water and sediment were analyzed,adopting the risk assessment of SQG-Q-based sediment heavy metal pollution.This study provides a comprehensive and accurate method to evaluate the environmental risk of tailings ponds in downstream water bodies.This paper will support the follow-up study on systematic aquatic environmental risk assessment of tailings ponds.
