abstract:
According to the characteristics of acid mine drainage in the Shandi River Basin of Yangquan City, acid mine drainage with low pH value and high Fe2+ and Mn2+ concentration was prepared. Carbon steel slag was used to treat it, so as to investigate the factors influencing the removal rate and discuss the removal mechanism. The results show that the removal rate of Fe2+ by steel slag is as high as 98.72%, and the removal rate of Mn2+ is only 39.79%. After the treatment of acid mine drainage, Fe(OH)3 is produced on the surface of steel slag, but no new Mn-containing substances are produced, which proves that the removal of Fe2+ is dominated by chemical reactions, and the removal of Mn2+ is dominated by adsorption.
