Ammonia-containing wastewater treatment apparatus

The invention discloses an ammonia-containing wastewater treatment apparatus, which comprises: a reaction part provided with at least a reaction tower capable of treating ammonia-containing wastewater; an ozone supply part capable of supplying ozone to the wastewater in the reaction tower; and a bromine ion supply part capable of supplying bromine ions to the wastewater treated by the reaction tower. According to the present invention, the bromine ions are supplied to the wastewater by the bromine ion supply part so as to adjust the bromine ions in the wastewater treated by the reaction towerto the predetermined concentration, and the ozone supply part supplies the ozone to the wastewater treated by the reaction tower so as to adjust the supply rate of the ozone supplied to the reaction tower, such that the bromine ion concentration and the ozone supply rate of the wastewater of the reaction tower can be optimally adjusted so as to avoid the excess ozone supply rate by controlling thebromine ions in the waste
