【摘要】 粉煤灰是火力发电厂的主要废弃物,能够污染地下水,造成严重的环境问题,而酸性矿井水也是工业污染和地下水资源损失的重要因素。用粉煤灰直接与模拟酸性矿井水作用,探讨作用过程中体系pH,总硬度以及总铁浓度的变化,说明混合灰水作用既有中和又有吸附和絮凝等协同作用。更多还原

【Abstract】 Fly ash is a main offal of the thermal power plant,Which can pollute the groundwater and cause the serious environment problems.Acid mine drainage is the industrial pollution sources,which can cause a large number of water resource loss and destroy the groundwater resource.The process that fly ash treats simulated acid mine drainage were studied through determination pH value,content of Fe and Ca,Mg.The result show neutral effect,absorb effect and so on coordinate action in the process.更多还原
