METHOD FOR REMOVING MAGNETIZED POWDER STRENGTHENED NITRATE NITROGEN AND INORGANIC PHOSPHORUS

摘要

A method for removing magnetized powder strengthened nitrate nitrogen and inorganic phosphorus, comprising the following steps: (1) mixing permanent magnet material powder with paramagnetic Fe ₃O ₄ powder, magnetizing the mixture in a magnetic field to prepare magnetized powder; (2) adding the magnetized power directly into a water treatment reaction vessel or preparing the magnetized power into granular fillers and then adding the same into a water treatment reaction vessel; and (3) allowing water to be treated to enter the water treatment reaction vessel, and performing chemical reaction of removing nitrate nitrogen and inorganic phosphorus in the presence of a reducing agent, and discharging the water after the reaction.
