【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。更多还原

【Abstract】 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,NH+4-N,NO-2-N,NO-3-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.更多还原
