摘要
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, NH4^#-N, NO2^--N, NO3^--N and pH, and of microbial test, the results revealed that the optimal Anammox performance was achieved from 2^# reactor in which COD/NH4^+ -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 NH4^+-N consumed : NO2^- -N consumed : NO3^- -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 NH4^+-N was fed for the reactors, the ratio of NO2^- -N consumed: NH4^+-N consumed was in the range of 1.51-2.29 and the ratio of NO;-N produced: NH4^+ -N consumed in the range of 0 -0.05.
