【摘要】[ Objective] The aim was to study the start-up process of multistage anoxic-anaerobic-aerobic sequencing batch rector (SBR) for removing nitrogen and phosphorus. [ Method] Biological removal of nitrogen and phosphorus species from a synthetic wastewater was investigated in a SBR operated under a variable aeration strategy to achieve the most desirable anoxic-anaerobic-aerobic stages in each cycle. [ Result] Operating parameters of the SBR process was as follows： 75 min anoxic → 35 min anaerobic ( including entering water) → 120 min aerobic → 75 min anoxic → 35 min anaerobic ( including entering water) → 120 min aerobic → 75 min anoxic → 35 min anaerobic ( including entering water) → 120 min aerobic → 30 min static precipitation, and the elimination ratio of COD, TN and TP was 85.0％, 80.0％ and 85.0％ respectively.[ Conclusion ] The research provides theoretical basis for studies on the removal of nitrogen and phosphorus species from wastewater.%[目的]研究多级缺氧、厌氧、好氧交替序批式反应器(SBR)进行脱氮除磷的启动过程.[方法]以人工配水为研究对象,采用缺氧、厌氧、好氧多级交替SBR工艺进行了脱氮除磷.[结果]SBR工艺的运行参数为缺氧75 min→厌氧35 min(包括进水)→好氧120min→缺氧75min→厌氧35
