Effect of organic matter on the performance and N2O emission of a granular sludge anammox reactor

Abstract
A continuously fed bubble column granular sludge anammox reactor was operated for 405 days to investigate the effect of organic matter on the reactor performance and N2O emission. Results showed that influent COD improved the nitrogen removal of the anammox reactor at low influent COD/TN ratios (ca. 0.1); however, a concurrent increase in N2O emission was observed. The average N2O emission increased by 2.5 times (p < 0.05) with increasing influent COD concentration, accounting for up to 0.46% of the incoming nitrogen load. A generalized method was demonstrated and applied to derive the anammox stoichiometry from experimental data for improved mass balance. Mass balance revealed that approximately 18% of the nitrate produced from anammox conversion was reduced via heterotrophic denitrification to nitrite, and 29% of this produced nitrite was further released as N2O. In addition, it was found that the experimentally measured anammox biomass yield in the overall metabolic reaction has been mistakenly used as the catabolic yield in many modelling studies. Solutions were proposed.
