PURPOSE: A pre-processing device and a method thereof, for inducing an anaerobic denitrogen reaction are provided to stably oxidize ammonia nitrogen inside ammonia wastewater. CONSTITUTION: A pre-processing device for inducing an anaerobic denitrogen reaction comprises an oxygen tank(10), a nitrozation tank(20), and a mixing tank(30). The oxygen tank is inserted with ammonia wastewater containing ammonia nitrogen, and increases the dissolved oxygen concentration inside the wastewater by supplying oxygen using an oxygen supply device. The nitrozation tank oxidizes the ammonia nitrogen. |
