Claim 1:
2. The anaerobic-AO-SACR combined advanced nitrogen removal system for high ammonia-nitrogen wastewater according to claim 1, wherein:
the volume of the anoxic zone of the AO reactor and the volume of the aerobic zone of the AO reactor are determined according to the output of wastewater and the total nitrogen concentration of pollutants;
volume of the anoxic zone=a×(total nitrogen concentration of high ammonia-nitrogen wastewater/50×3×wastewater output per hour) m3, and volume of the aerobic zone=a×(total nitrogen concentration of high ammonia-nitrogen wastewater/50×12×wastewater output per hour) m3; wherein a ranges from 1 to 1.5, the total nitrogen concentration of the high ammonia-nitrogen wastewater is in mg/L, and the wastewater output per hour is in m3.
