Abstract

"A device and method for anaerobic ammonium oxidation coupling heterotrophic denitrification of coal chemical wastewater" relates to a device and method for removing ammonia nitrogen in high-ammonia nitrogen coal chemical wastewater through stable and efficient anaerobic ammonium oxidation coupled heterotrophic denitrification, which belongs to In the technical field of biochemical sewage biological treatment, it is suitable for the treatment of coal chemical wastewater and other high-ammonia nitrogen organic industrial wastewater such as anaerobic digestion biogas slurry, aquaculture wastewater, and monosodium glutamate wastewater.

Description

technical field [0001] The invention relates to a device and method for removing ammonia nitrogen in high-ammonia-nitrogen coal chemical wastewater through stable and efficient anaerobic ammonium oxidation coupling heterotrophic denitrification, which belongs to the technical field of biochemical sewage biological treatment, and is suitable for coal chemical wastewater and other such as anaerobic Digestive biogas slurry, aquaculture wastewater, monosodium glutamate wastewater and other high ammonia nitrogen organic industrial wastewater treatment. Background technique [0002] Coal chemical industry is the process of converting coal into gas, liquid, solid fuel and chemicals through chemical processing. The quality of coal chemical wastewater varies due to differences in production processes and equipment. It is a typical high ammonia nitrogen organic industrial wastewater. The COD concentration in the wastewater is about 1500-6000mg / l, and the ammonia nitrogen is 400-1500mg...
