| 摘 要： | 采用序批式活性污泥反应器(SBR)对生活污水短程及全程硝化反硝化过程中N2O的产生量进行了考察.结果表明,在进水氨氮浓度相同且不限制DO的条件下,全程硝化反硝化过程中N2O的总产生量为短程硝化反硝化的2倍左右;硝化类型不会影响反硝化过程对溶解性N2O的还原,无论以(NO2-)-N还是以(NO3-)-N为电子受体,反硝化过程均有利于降低N2O的浓度.

| Abstract: | The sequencing batch reactor(SBR) was adopted to investigate N2O production quantity in complete and shortcut nitrification and denitrification for sewage treatment.The results show that under the condition of same ammonia nitrogen concentration and not controlling DO concentration,the N2O production quantity in complete nitrification and denitrification process is twice of that in shortcut nitrification and denitrification process.The nitrification types do not affect the reduction of soluble N2O in denitr... |
