摘　　要：以实际生活污水为处理对象,就缺氧区与好氧区容积比对Carrousel 2000氧化沟同步脱氮除磷的影响进行了研究。在缺氧区与好氧区的容积比分别为0.35、0.49、0.64的条件下,Carrousel 2000氧化沟对氨氮的平均去除率分别为92.96%、94.93%和97.60%,对总磷的平均去除率分别为80.22%、86.55%和92.30%,对COD的去除率均在90%以上。此外,如果继续增大缺氧区与好氧区的容积比,应适当调整内循环比,否则缺氧区会因硝酸盐浓度不够而发生二次释磷现象。The influence of the volume ratios of anoxic zone to aerobic zone on simultaneous removal of nitrogen and phosphorus in the Carrousel 2000 oxidation ditch for treating domestic sewage was studied. When the volume ratios of anoxic zone to aerobic zone were 0.35, 0.49 and 0.64 respectively, the average removal rates of NH4^＋ - N were 92.96%, 94.93% and 97.60% respectively, those of TP were 80.22%, 86.55% and 92.30% respectively, and those of COD were all higher than 90%. In addition, if the volume ratios of anoxic zone to aerobic zone continue to be increased, the internal recirculation ratio should be adjusted, otherwise the nitrate concentration would not be enough in anoxic zone and phosphorus would be released again.
