The invention discloses a device for enriching anaerobic ammonia-oxidizing bacteria and a method for treating wastewater by using the device, and relates to the technical field of sewage treatment. The invention aims to solve the problems of long anaerobic ammonia oxidation starting time and slow growth of anaerobic ammonia oxidizing bacteria in the anaerobic ammonia oxidation technology. The method comprises the following steps that: an air pump is started, mixed wastewater is aerated through an aerator, the concentration of dissolved oxygen in the mixed wastewater is adjusted to 0.5-1.5 mg/L, and then the air pump is turned off; a PLC is used for controlling a substrate concentration measuring device to measure the concentration of organic matters in the mixed wastewater, when the proportion of nitrite ions to ammonium ions is lower than 1.1, the PLC is used for automatically controlling a nutrient substance adding port to add nutrient substances into a reaction tank, the operation is continued, and after the anaerobic ammonia oxidation reaction in the reaction tank is finished, the motor is turned off. The invention can obtain the device for enriching the anaerobic ammonia-oxidizing bacteria and the method for treating the wastewater by using the device.
