The utility model relates to a converter turbid recirculating water treatment device by utilizing a superconducting high-gradient magnetic field, belonging to the field of environmental protection and treatment of industrial waste water hard to treat. The converter turbid recirculating water treatment device treats converter turbid recirculating water by utilizing an inclined plate settling tank and wirehaired high-gradient treater. Due to the action of strong magnetization and strong absorption of the superconducting high-gradient magnetic field, the strong magnetic ferric oxide substances in waste water is absorbed, and weak magnetic substances, even non-magnetic substances, such as calcium oxide, silicon dioxide, magnesium oxide and the like, also can be absorbed; the concentration of suspended particles of the treated waste water is reduced from 1216mg/L to 5mg/L, the turbidity is reduced from 2837.5NTU to 22.25NTU, and both the concentration and the turbidity achieve national emission standards.
