The utility model relates to a tailing pond seepage water multi-stage treatment device which comprises a first-stage iron-manganese waste ore powder tank, a flow guide plane, a heavy metal removal tank, a windmill aeration device, a second-stage treatment tank, a third-stage treatment tank, a fourth-stage ecological tank, a medicine box, a water pipe and a valve switch. The seepage water in the tailing pond flows into the first-stage iron-manganese waste ore powder pond, iron-manganese ions are generated by adjusting the pH value, iron-manganese oxides are generated by the iron-manganese ions and have adsorption and wrapping effects on metal ions, the metal ions are precipitated and separated from the seepage water, COD in the seepage water can be reduced by the polymeric flocculant, and finally the seepage water is discharged into the external environment through the fourth-stage ecological pond. The device integrates tailing pond seepage water treatment and ecological landscape, is simple in structure, conv
