Abstract:

A set of 4.5-L upflow anaerobic sludge blanket (UASB) bioreactor was used to perform the anaerobic ammonium oxidation (ANAMMOX) and denitrification of leachate generated from a landfill site in Guangdong, China. The results show that there exists a synergistic effect of ANAMMOX and denitrification in the UASB bioreactor, that the average removals of NH4^+ -N and NO2-N from the 120th day on are respectively 94.79% and 98.17%, that the maximum and average CODcr removals are respectively 51.68% and 23.51% , and that the average removal of volumetric loading reaches 84.53 mg/(L·d).

Key words: landfill leachate, anaerobic ammonium oxidation, denitrification, synergistic effect, electronic stoichi-ometry
