| Abstract: | By adopting the method of precipitaton and neutralization by limestione and absorption by flyash, better results can be achieved in disposal of the acid waste water in the colliery. 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 10g/l. |
