A SMBBR was established to treat medium ammonium under room temperature. Results showed that TN load can reach 0.16 kg·(m·d), and the average TN removal efficiency was (51.58±6.80)% in the SMBBR with an influent ammonia concentration of 100 mg·L and DO of 0.4-0.7 mg·L. AOB, ANAMMOX, and NOB activity reached (2253.21±502.10) mg·(m·d), (4847.46±332.89) mg·(m·d), and (1455.17±473.83) mg·(m·d), 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.
建立了一个序批式移动床生物膜反应器（SMBBR）在室温下处理中等浓度的铵。结果表明，在进水氨氮浓度为100mg/L、溶解氧为0.4 - 0.7mg/L的SMBBR中，总氮负荷可达0.16kg·(m³·d)，平均总氮去除效率为(51.58±6.80)%。氨氧化细菌（AOB）、厌氧氨氧化菌（ANAMMOX）和亚硝酸盐氧化菌（NOB）的活性分别达到(2253.21±502.10)mg·(m³·d)、(4847.46±332.89)mg·(m³·d)和(1455.17±473.83)mg·(m³·d)，并且发现厌氧氨氧化菌和氨氧化细菌形成了良好的协同关系。定量聚合酶链反应（PCR）结果表明，厌氧氨氧化菌、氨氧化细菌和亚硝酸盐氧化菌的相对丰度分别为11.57%、1.01%和0.94%。单级部分亚硝化 - 厌氧氨氧化工艺的稳定运行，为中等氨氮废水处理提供了一种替代技术。
