Provided is an oxidation pond for treating acid mine drainage discharged from an abandoned mine. The oxidation pond comprises: an inlet into which mine drainage is introduced; a retention pond in which the mine drainage introduced into the inlet resides; and an outlet through which the mine drainage is discharged from the retention pond, so that iron in the mine drainage is oxidized and precipitated during residence of the mine drainage in the retention pond, wherein a neutralizing agent that increases the pH of the mine drainage to accelerate the iron precipitation reaction is placed in the retention pond. |
