Currently, since the discovery of the anaerobic ammonia oxidation
(ANAMMOX) bacteria, autotrophic nitrogen removal processes
have received considerable attention (Strous et al., 1999; van der
Star et al., 2007). In such processes, NH4 + -N could be converted to
nitrogen gas by cooperation between the ammonia oxidizing bacteria
and the ANAMMOX bacteria (Khin and Annachhatre, 2004),
without any addition of a carbon source. However, almost all the
research focusing on autotrophic nitrogen removal is related to
wastewater containing high NH4 + -N, while not much is being
reported in the field of water supply on the autotrophic ANAMMOX
bacteria.
Therefore, in this paper, the autotrophic removal nitrogen process
was identified in accordance with the operational results of
the biological Mn and NH4 + -N removal biofilter, and, in addition,
the influence of the biofilter on the removal of NH4 + -N was calculated.
Moreover, the functional ANAMMOX bacteria were also analyzed
using polymerase chain reaction (PCR) amplification
technology.
