A one-stage anaerobic ammonium oxidation (ANAMMOX) reactor can be quickly started within 40 days by mixing partial nitrifying sludge with ANAMMOX granular sludge with an average temperature of 30 °C. After 70 days of nitrogen load acclimation, including became the dominant strain of the system within the reactor, which exhibited high efficiency and a stable nitrogen removal performance. At an influent chemical oxygen demand (COD), NH-N content, total nitrogen (TN) content, hydraulic retention time (HRT), temperature, and reactor dissolved oxygen (DO) content of 100, 60, and 70 mg/L, 6 h, 30 ± 1 °C, and below 0.6 mg/L, respectively, the one-stage ANAMMOX reactor could effectively treat domestic sewage on campus. The removal rates of COD, NH-N, and TN were approximately 89%, 96.7%, and 70%, respectively.
在平均温度为 30°C 的条件下，将部分硝化污泥与 ANAMMOX 颗粒污泥混合，可在 40 天内快速启动一级厌氧氨氧化（ANAMMOX）反应器。经过 70 天的氮负荷驯化后， 成为系统内的优势菌株，表现出高效且稳定的脱氮性能。在进水化学需氧量（COD）、NH-N 含量、总氮（TN）含量、水力停留时间（HRT）、温度和反应器溶解氧（DO）含量分别为 100、60 和 70mg/L、6h、30±1°C 和低于 0.6mg/L 的条件下，该一级 ANAMMOX 反应器可有效处理校园生活污水。COD、NH-N 和 TN 的去除率分别约为 89%、96.7%和 70%。
