Start-up of a pilot-scale ANAMMOX reactor for low-carbon nitrogen removal from anaerobic digestion effluent of kitchen waste

The pilot-scale simultaneous denitrification and methanation partial nitrification anaerobic ammonia oxidation system was designed to treat anaerobic digestion effluent of kitchen waste . The SDMPN was first started to avoid the inhibition of high-concentration pollutants. Subsequently, ANAMMOX was coupled to realize autotrophic nitrogen removal. Shortcut nitrification-denitrification achieved efficient performance by the SDM-PN.
