摘　　要：在研究期间主要分析AOA工艺模式下An AOB处理市政污水效果。以某污水处理厂AOA工艺为例,利用实验分析方法探究市政污水处理效果。对污水中的主要参数指标分析可知:工艺中反硝化速率相对较高,COD在厌氧池的去除率达到90%左右,主要原因在于内碳源化和外回流稀释效果;氧池曝气量逐渐减少,NH_(4)^(+)-N去除率从80%上升至95%以上,出水NO_(3)^(-)-N质量浓度从8mg/L下降为5mg/L,AnAOB活性已经成功驯化;缺氧池的NH_(4)^(+)-N、NO_(2)^(-)-N的去除量分别为15 mg/L、3 mg/L,而NO_(3)^(-)-N的生成量并不超过1 mg/L,说明在缺氧池存在多种脱氮途径。希望通过研究为市政污水处理提供一定参考,以此保证Anammox反应运行的稳定性与安全性。During the research period,the main focus was on analyzing the effectiveness of AnAOB in treating municipal wastewater under the AOA process mode.Taking the AOA process of a certain sewage treatment plant as an example,experimental analysis methods are used to explore the effectiveness of municipal sewage treatment.The analysis of the main parameter indicators in sewage shows that the denitrification rate in the process is relatively high,and the COD removal rate in the anaerobic tank reaches about 90%,mainly due to the internal carbon source and external reflux dilution effect.The aeration rate of the oxygen tank gradually decreased,and the NH_(4)^(+)-N removal rate increased from 80%to over 95%.The mass concentration of NO_(3)^(-)-N in the effluent decreased from 8mg/L to 5mg/L,and the AnAOB activity has been successfully domesticated.The removal rates of NH_(4)^(+)-N and NO_(2)^(-)-N in the anoxic tank were 15 mg/L and 3 mg/L,respectively,while the generation of NO_(3)^(-)-N did not exceed 1 mg/L,indicating the existence of multiple denitrification pathways in the anoxic tank to provide some reference for municipal sewage treatment through research,and ensure the stability and safety of Anammox reaction operation.
