Goaf purifying characteristic of mine water with high turbidity, high concentration of iron and manganese

Taking mine water with high iron and high manganese as research object, kinetic parameter experiment were carried out by goaf filling. The result shows that dispersion coefficient and adsorption coefficient of goaf filling are D=3.12m
