摘　　要：以人工模拟高氨氮废水为研究对象,采用循环间歇式曝气方式,以溶解氧浓度(DO)和pH值为过程控制参数,对SBR系统进行实时控制、全程跟踪。根据此过程中COD、NH4+-N、NO2--N和NO3--N 4项水质指标的变化情况,研究SBR系统中的短程硝化反硝化工艺。实验结果表明,在短程硝化反硝化工艺中,采用较高曝气量,并且在曝气过程中用DO和pH值作为过程控制参数是可行的。Taking artificially prepared high ammonia nitrogen wastewater as the research object, using the cycle intermittent aeration process,and taking dissolved oxygen density （DO）and pH as control parameters, the real-time control and whole course tracing of sequencing batch reactor（SBR） was conducted. According to the changes of four water indexes COD, NH4-N, NO2--N, NO3-N, the shortcut nitrification-denitrification in SBR was studied. The experimental results showed that it is feasible to take high-strength aeration and to use DO and pH as the control parameters in process of nitrification-denitrification.
