摘　　要：在厌氧/好氧SBR反应装置中,以模拟城市污水为处理对象,研究不同碳源浓度对同步硝化反硝化协同除磷效果的影响,同时对该过程中ORP的变化规律及影响作了探讨。结果表明,碳源浓度的变化对该系统中有机物和总磷的去除影响不显著,COD和TP的去除率分别>95%和90%,出水TP在0.5mg/L以下,当C/N比为6.7时,总氮去除率高达98.4%。本试验条件下,当COD:TN:TP约为200:30:7时,系统同步脱氮除磷运行效果最佳。A lab-scale sequencing batch reactor （SBR） was operated to treat simulative urban sewage in alternating anaerobic-aerobic mode. ORP during the process was studied, and it proved that removals of COD and TP, being 95% and 90% respectively, had less dependence upon the carbon source. At the same time, the experimental result showed the removal of TN reached 98.4% when C/N ratio being 6.7, and suggested the optimum condition of simultaneous de-nitrification and P removal with respect to the ratio of COD： TN： TP.
