  • 摘要: 基于正交实验考察了溶解氧(DO)、初始NH4+-N浓度、pH对SBR自营养脱氮性能的影响。结果表明,DO和NH4+-N浓度对好氧氨氧化速率影响大,pH对好氧氨氧化速率的影响小;DO、NH4+-N浓度对亚硝酸氧化速率的影响较大,pH对亚硝酸氧化速率的影响较小;DO、NH4+-N浓度和pH对厌氧氨氧化菌(ANAOB)的活性影响较小。好氧氨氧化菌(AOB)直接影响到CANON系统的总氮去除能力,是CANON系统的控制反应,DO是关键控制因子。实验确定的CANON系统优化运行条件为,DO (0.3±0.05)mg/L、初始NH4+-N浓度150 mg/L和pH 7.4。
    Abstract: Orthogonal test method was used to investigate the effects of DO concentration, initial NH4+-N concentration and pH on CANON (completely autotrophic nitrogen removal over nitrite) performance of SBR. The results indicated that DO and initial NH4+-N concentrations had significant effects on aerobic ammonium oxidation rate while the effect of pH was not significant; DO and initial NH4+-N concentrations had significant effects on nitrite oxidation rate while the effect of pH was not significant; DO, initial NH4+-N concentrations and pH had little effect on anaerobic ammonium oxidation rate. Aerobic ammonium oxidation, as controlling reaction of CANON process, directly determined the system's total nitrogen removal capacity, and DO concentration was the key factor. The optimal operating conditions of the CANON process were determined as follows: the optimal DO concentration of (0.3±0.05)mg/L, the optimal initial NH4+-N concentration of 150 mg/L and the optimal pH of 7.4.
