Method for cooperatively repairing mine tailing composite heavy metal pollution by utilizing functional microorganisms and honeycomb type electric driving technology

The invention provides a method for synergistically restoring mine tailing composite heavy metal pollution by utilizing functional microorganisms and a honeycomb type electric driving technology, and aims to restore the mine tailing composite heavy metal pollution by utilizing acid-producing functional microorganisms to convert machine wastes to produce acid and cooperating with the honeycomb type electric field driving technology. The method specifically comprises the following steps: adding a repairing modifier generated by mixing functional microorganisms and organic wastes into to-be-repaired tailings, then adding enough water for soaking, and dividing the to-be-repaired tailings into a plurality of treatment units in a regular hexagonal honeycomb type layout structure, graphite carbon electrode bars are placed at each vertex and the center of a regular hexagon to construct a repair electric field, a cylindrical cathode is arranged at the center, and liquid in a cylindrical cathode tank is extracted in ti
