  • Patent number: 11919790
    Abstract: An anaerobic-AO-SACR combined advanced nitrogen removal system for high ammonia-nitrogen wastewater, in which high ammonia-nitrogen wastewater first enters an anaerobic reactor to remove most of organic matters from the wastewater, effluent water enters an AO reactor for nitrogen removal by pre-denitrification in an anoxic zone and for removal of the remaining organic matters and nitrification of ammonia nitrogen in an aerobic zone, and then the effluent water enters an intermediate pool. Meanwhile, under the control of a water quality testing device and a PLC controller, a part of raw water is introduced into the intermediate pool to adjust the carbon nitrogen ratio of the wastewater.
