摘　　要：采用序批式活性污泥反应器（SBR）处理模拟城市污水，在厌氧一好氧运行方式下，考察了DO对同步硝化反硝化协同除磷效果的影响。结果表明，DO的变化对该系统中有机物的去除影响不显著，当DO为1．5～2．0mg／L时，TN及TP去除率均能达到90％以上，并可以应用pH曲线拐点来判断系统硝化过程是否完成。The sequencing batch reactor （SBR） was used to treat simulated urban sewage. The effect of DO on simultaneous nitrification-denitrification with phosphorus removal was investigated in anaerobic-aerobic mode. The results show that： The effect of DO on the removal of organic substance in the system is not significant; When DO is 1.5 - 2.0 mg/L, the removal rates of TN and TP are both above 90% ; And the inflection point of pH curve can indicate the finish of nitrification process in the system.
