The performance of an ANAMMOX(anaerobic ammonium oxidation) fixed-bed reactor was tested and the process kinetics characteristics of the reactor was analyzedThe ANAMMOX reactor was successfully operated within 86 days with denitrifying activated sludge as inoculumWhen operated at a hydraulic retention time of 2 h and influent total nitrogen of 608 mg·L-1
corresponding to a nitrogen loading rate of 7.34 kg·m-3·d-1
the maximum total substrate removal rate of 6.11 kg·m-3·d-1 was observedSecondorder and a modified StoverKincannon models well fitted the ANAMMOX fixed reactor under the substrate noninhibition conditionsThe maximum total substrate removal rate achieved in this study was still far lower than the theoretical value 12.4 kg·m-3·d-1 deduced from the Stover Kincannon model
which indicated great potential in improving reactor performance.
