| 摘 要： | 初步分析RMCH型净化槽生物硝化反应中出现NO2 -N积累的原因 ,以及影响亚硝酸积累的不同因素。结果表明 ,进水高浓度氨氮是产生不完全硝化和NO2 -N积累的重要原因 ;DO的不足是另一个主要因素 ;进水的C/N比与NO2 -N积累以及积累量有直接的相关关系 ;好氧槽中水力停留时间的减少和容积负荷的增加也影响了NO2 -N积累。本文还提出了厌氧槽中出现氨氮厌氧氧化的可能性分析

| Abstract: | The reasons for nitrite accumulation in RMCH Johkasou and effects on nitrite accumulation are analyzed. The results show that high concentration of ammonia-N is an important factor bringing about nitrite accumulation, and deficient DO is another important factor. The C/N ratio of influent is relevant to nitrite accumulation. Where C/N ratio is minimum, there is maximum nitrite accumulation. HRT and volumetric loading of ammonia-N are responsible for nitrite accumulation. Possibility on anaerobic oxidation of ammonia in anaerobic tank is represented. |
