Disclosed is a method for promoting denitrification through magnetic resin to remove nitrate nitrogen from water. In the method, a magnetic anion exchange resin is in contact with and mixed with sewage, and by means of the dual effects of an ion exchange between the magnetic anion exchange resin and nitrate nitrogen in the sewage and denitrification being enhanced by the magnetic material, the quick and efficient removal of the nitrate nitrogen from the sewage is realized, and at the same time, the regeneration and reuse of the magnetic anion exchange resin are realized by means of the denitrification of microorganisms. The method can shorten the amount of time that sewage stays in a reactor, and at the same time, can also reduce the volume of the reactor and improve the removal effect of the nitrate nitrogen from the sewage. |
