NOVELTY - Treating water for nitrogen-doped reduced graphene oxide to strengthen Fenton oxidation comprises adding hydrogen peroxide, nitrogen-doped reduced graphene oxide and homogeneous ferric ion solution to the wastewater to be treated with a pH value of 2-3.6, treating waste water for 30-60 minutes under stirring condition, finishing the waste water treatment, recycling nitrogen-doped reduced graphene oxide for next batch of wastewater treatment after completing the treatment of a batch of wastewater, controlling the addition of hydrogen peroxide so that the concentration of hydrogen peroxide in the wastewater to be treated is 0.1-10 mmol/l, controlling addition of nitrogen-doped reduced graphene oxide so that the concentration of nitrogen-doped reduced graphene oxide in the wastewater to be treated is 2-250 mg/l and controlling the addition amount of homogeneous ferric ion solution so that the concentration of the ferric ion in the waste water to be treated is 5-200 µmol/l. USE - The method is useful for treating water for nitrogen-doped reduced graphene oxide to strengthen Fenton oxidation. ADVANTAGE - The method improves the reactivity of iron (III) by introducing nitrogen-doped reduced graphene oxide and realizes continuous and efficient treatment of wastewater.
