Electromagnetic-separation aeration and greening water-treatment equipment

The invention relates to electromagnetic-separation aeration and greening water-treatment equipment which comprises an oil-removal separating tank, a synergism treatment tank and a magnetic-separationaeration composite zone. An electrochemical oil-removal device is arranged at the top of the oil-removal separating tank and a drain outlet is arranged at the lower portion of the electrochemical oil-removal device; at least one magnetic separating tank and one aeration tank are arranged in the magnetic-separation aeration composite zone, the magnetic separating tank consists of an adsorption settling bin and a pollutant discharging bin, and a lifting rotation mechanism is arranged in the magnetic separating tank and is connected with and controls a magnetic separating device; an aeration device is arranged in the aeration tank and a filter device for intercepting magnetic powder to separate pollutants is arranged in the pollutant discharging bin; the different tanks are connected with and controlled by valves th
