摘要：
A SMBBR was established to treat medium ammonium under room temperature. Results showed that TN load can reach 0.16 kg•(m3•d)-1, and the average TN removal efficiency was (51.58±6.80) % in the SMBBR with an influent ammonia concentration of 100 mg•L-1 and DO of 0.4-0.7 mg•L-1. AOB, ANAMMOX, and NOB activity reached (2 253.21±502.10) mg•(m2•d)-1, (4 847.46±332.89) mg•(m2•d)-1, and (1 455.17±473.83) mg•(m2•d)-1, and ANAMMOX and AOB bacteria were found to develop a good collaborative relationship. Quantitative PCR results showed that the relative abundance of ANAMMOX, AOB and NOB were 11.57%, 1.01% and 0.94%, respectively. The stable operation of single stage partial nitritation-ANAMMOX process provide an alternative technology for medium ammonia wastewater. © 2021, Science Press. All right reserved.
