Abstract: Disclosed are an ammonia-containing wastewater treatment method and an apparatus, of which a main structure includes an ammonia wastewater holding tank receiving therein ammonia-containing wastewater, at least one ammonia nitrogen detection element detecting ammonia nitrogen content of the ammonia-containing wastewater, at least one aeration device connected to the ammonia wastewater holding tank, an oxygen transfer coefficient calculation device in information connection with the aeration device. The aeration device includes an aeration time controller and a gas flowrate controller. As such, a total mass of oxygen entering the ammonia wastewater treatment tank can be precisely controlled by adjusting output time and output amount per unit time of the aeration device and calculating an oxygen transfer coefficient-aeration flowrate relationship of the aeration device, so that a ratio between the ammonia nitrogen mass and the oxygen mass can be controlled to have ammonium nitrogen first oxidized into nitrite before being oxidized into nitrate.
