Abstract: The feasibility of the nitrous organic wastewater treated was
studied in seven anaerobic sequencing batch reactors (ASBRs)
(0^#–6^#) which had been run under
stable anaerobic ammonium oxidation (Anammox). By means of monitoring and data
analysis of COD, NH_4^+-N, NO_2^--N,
NO_3^--N and pH, and of microbial test, the results revealed
that the optimal Anammox performance was achieved from 2^#
reactor in which COD/NH_4^+-N was 1.65, Anammox bacteria and
denitrification bacteria could coexist, and Anammox reaction and
denitrification reaction could occur simultaneously in the reactors. The ratio
of NH_4^+-N consumed: NO_2^--N consumed:
NO_3^--N produced was 1:1.38:0.19 in 0^#
reactor which was not added glucose in the wastewater. When different ratio of
COD and NH_4^+-N was fed for the reactors, the ratio of
NO_2^--N consumed: NH_4^+-N consumed was
in the range of 1.51–2.29 and the ratio of NO_3^-<FORMULA>-N
produced: NH<FORMULA>_4^+-N consumed in the range of
0–0.05.
