摘　　要：为进一步提高AAO工艺对污染物的去除效果,本文在研究过程中利用理论和实践结合的方法,将某城市污水处理厂作为研究对象,分析AAO工艺好氧段分段供氧对污染物去除效果的影响。在研究期间将AAO工艺好氧段分成三个阶段,探究不同供氧段对污染物去除效果的具体影响。通过研究得出结论,AAO工艺好氧段不同段的影响效果并不相同,且将好氧段首段、中段与尾段的DO质量浓度控制在4~5 mg/L、3~4 mg/L和2~3 mg/L区间具有较好的去除效果。In order to further improve the removal efficiency of pollutants by AAO process,this paper uses a combination of theoretical and practical methods to analyze the impact of segmented oxygen supply in the aerobic section of AAO process on pollutant removal efficiency in a certain urban sewage treatment plant.During the research period,the aerobic section of the AAO process was divided into three stages to explore the specific effects of different oxygen supply sections on pollutant removal efficiency.Through research,it has been concluded that the effects of different aerobic stages in the AAO process are not the same,and controlling the DO mass concentration in the first,middle,and last stages of the aerobic stage within the range of 4~5 mg/L,3~4 mg/L,and 2~3 mg/L has a good removal effect.
