Abstract
In view of the current pollution to sewage by nitrate nitrogen, the present invention discloses a method for promoting denitrification to remove nitrate nitrogen in water by magnetic resins. In the method disclosed by the present invention, magnetic anion exchange resins are in contact with and mixed with sewage, and nitrate nitrogen in the sewage is removed quickly and efficiently by both the ion exchange between the magnetic anion exchange resins and the nitrate nitrogen in the sewage and the denitrification enhanced by the magnetic material. Meanwhile, the regeneration and recycle of the magnetic anion exchange resins are realized by the denitrification of microorganisms.
