Start-up characteristics of anaerobic ammonia oxidation (ANAMMOX) biological filter reactor
Translated Abstract
The start-up characteristics of anaerobic ammonium oxidation (ANAMMOX) process were inves- tigated applying laboratory scale parallel experiments. The experiments were carried out with an up-flow ANAM- MOX filter reactor under various conditions of temperature, sludge inoculation and initial concentration of hydra- zine and hydroxylamine. The analysis of results demonstrated that temperature was the major factor influencing the activities of the ANAMMOX bacteria. In addition, under the conditions of seeding 200 mL of ANAMMOX ac- tivited sludge, darkness, 38℃ and without adjustment of hydrazine and hydroxylamine, the reactor was success- fully started up in 45 days. During the testing period, the stoichiometric molar ratio of NH4+ -N: NO2- -N: NO3- -N maintained at 1: 1.17: 0.30. 87.38% of total nitrogen removal rate was achieved, corresponding to the maxi- mum 1.41 kg/(m3 · d) of total nitrogen volume loading.
