【摘要】 本文分析了夏庄1号井排水在渠道中流动时水化学变化特征,指出在流动过程中pH、HCO₃^-、总硬度等逐渐升高,铁和铝含量逐渐降低.渠道内进行着中和作用、铁与铝的沉淀作用及二价铁的氧化作用.灰岩表面沉积的“铁壳”阻碍中和反应的进行.通过这些分析,对于用缺氧石灰石排水沟和建造湿地来治理酸性矿井排水提供依据更多还原

【Abstract】 Paper The variation of water chemical character of No. 1 well in Xiazhuang during flowing along the channel were analyzed in this paper. It shows that pH, HCO, and hardness rises gradually, Iron and aluminum drop gradually. It carries on the neutralization, precipitation of iron and aluminum and ferrous oxygenation alone the channel. The "Iron film" prevents the reaction between acid mining drainage and environmental rock. These provides the basis of prevention and treatment of acid mining water.更多还原
