The invention relates to the technical field of treatment of high-ammonia-nitrogen degradation-resistant organic wastewater, in particular to a method for advanced oxidation treatment of wastewater, which comprises the following steps: under the irradiation condition of an ultraviolet lamp, introducing ozone into the wastewater, adding a pro-oxidant, and carrying out UV/O3/hypochlorite advanced oxidation reaction to oxidize and remove ammonium ions while oxidizing and degrading organic matters; the pro-oxidant comprises hypochlorite. According to the constructed UV/O3/hypochlorite reaction system, the ozone utilization rate is increased, the oxidation activity of the reaction system is enhanced, ammonium ions can be oxidized through the oxidation effect of hypochlorite, the ammonium ions are converted into nitrogen to be released, the ammonia nitrogen removal efficiency is obviously enhanced, the overall reaction rate of the chain reaction is increased, and the method is suitable for industrial production.
