摘　　要：[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75 min→厌氧35 min(包括进水)→好氧120 min→缺氧75 min→厌氧35 min(包括进水)→好氧120 min→沉淀30 min,此时COD、TN、TP的去除率分别达85.0%、80.0%和85.0%。[结论]为污水的脱氮除磷研究提供了理论依据。[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.
