粉煤灰处理煤矿酸性废水的研究

Research on disposal of acidic wastewater in the mine by flyash

采用石灰石中和沉淀 ,粉煤灰吸附处理煤矿酸性废水 ,取得了良好的效果。用石灰石调节 p H至 4.5 ,再用石灰中和至中性 ,并用粉煤灰吸附 ,粉煤灰用量为 10 g/L时处理效果较好。

By adopting the method of precipitation and neutralization by limestone and absorption by flyash, better results can be achieved in disposal of the acid wastewater in the mine. The process goes like this: first, use limestone to neutralize the pH value to 4.5;then use lime to make it to neutral state and absorb it with flyash, whose appropriate amount is 10 g/L. ;
