The feasibility of the stable operation of a sequencing biofilm batch reactor (SBBR) for completely autotrophic nitrogen removal over nitrite (CANON) was investigated using aeration condition adjusting strategy, along with decreasing temperature and influent substrate (anammonia). The SBBR operated steadily for 223 days at 35℃ and high substrate[(446.47±43.77) mg NH4+-N/L] with the aeration regime of aeration/non-aeration=60min/60min; the total nitrogen removal rate (TNRR) and total nitrogen removal efficiency (TNRE) reached (0.49±0.07) kg N/(m3·d) and (84.3±4.6)%, respectively. After temperaute decreasd to 20~23℃, the intermittent aerobic condition was changed to aeration/non-aeration=40min/80min based on the ratio of NO2--N accumulation rate to NO2--N removal rate in the single-cycles. The TNRR and TNRE decreased to (0.43±0.04) kg N/(m3·d) and (69.5±5.7)% for 67days of operation, respectively. With gradual decreasing ammonia to (105.6±16.1) mg NH4+-N/L, the aeration/non-aeration time was regulated to 40min/80min, 30min/90min and 8min/32min in sequence. For 67days operation, the TNRR decreased to (0.16±0.02) kg N/(m3·d); nevertheless, the TNRE increased to (71.5±7.5)%. High-throughput sequencing results confirmed that the regulation strategy applied herein ensured the dominance of nitrogen removal functional bacterias in CANON system during decreasing temperature and substrate while the relative abundance of nitrite oxidizing bacteira was always below 0.1%.
