Abstract :
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=3.12m2/d, Kd (Fe)=11.07mL/g, Kd (Mn) =7.543mL/g respectively; Iron and manganese desorption rate is very low in goaf filling, and the highest desorption rates of iron, manganese are 29.29% and 33.85% respectively; Based on experiment result, iron and manganese fixed state adsorption capacity are 119.915 μg/g, 68.6 μg/g respectively.
