演马电厂粉煤灰矿井填充对地下水环境影响的模拟实验

Simulation Experiment on Influence of Mine Filling with Fly Ash from Yanma Power Plant on Groundwater Environment

对演马电厂粉煤灰进行浸泡和淋溶试验,模拟矿井填充后其对地下水环境的影响。测定了pH值,电导率,F-,总硬度,Zn,Mn,Cr6+,Cd,Cu,Pb等项目,实验表明,流动水体利于污染组分的溶出和迁移,溶出液中高锰酸盐指数和Cr6+超标,pH值偏高,淋溶条件下TDS和氯化物超标,对地下水环境存在污染。其它重金属元素含量甚微,多未检出。

Based on the soaking and continuous leaching experiments, this paper simulated its influence on groundwater environment after mine filling with fly ash from Yanma Power Plant. The indexes including pH value, conductivity, F-, total hardness, Zn, Mn, Cr6+, Cd, Cu, and Pb were measured in the experiments. The experiments showed that the flowing water is advantageous to the leaching-out and transformation of pollutants, and in the leaching liquid, the index of potassium permanganate and the value of Cr6 + exceeded the standards, and the value of pH is on the high side, under the condition of leaching experiment, the value of TDS 'total dissolved solid' and chloride exceeded the standards, they may pollute underground water. Other heavy metals were very few and most of then can't be detected.
