Acidification Characteristics of Reservoir Water Polluted by Acid Mine Drainage

  • 摘要: 矿业开发产生的酸性排水导致下游水体酸化,严重破坏水域生态平衡. 以受酸性矿山排水(Acid Mine Drainage,AMD)影响的水库水体为研究对象,通过对水库表层水、界面水和沉积物孔隙水中水质参数的变化进行分析,探讨水库水体酸化特征. 结果表明:表层水、界面水pH分别为3.22~3.38和2.70~3.02,水库上覆水体严重酸化,沿沉积物剖面向下酸化程度逐渐减弱;上游AMD在水库水体中存在自然净化过程,而表层沉积物可再次提高上覆水体酸度;沉积物孔隙水ρ(SO42-)极高(0.29~11.85 g/L)且在垂向剖面上变化波动较大,可能与沉积物中次生矿物的形成转化、季节及其他外界条件的变化有关.
