High NO and $ N_{2} $O accumulation during nitrite denitrification in lab-scale sequencing batch reactor: influencing factors and mechanism
Abstract Nitrous oxide ($ N_{2} $O) accumulation in biological nitrogen removal has drawn much attention in recent years; however, nitric oxide (NO) accumulation in denitrification was rarely studied. In this study, NO and $ N_{2} $O accumulation during nitrite denitrification in a lab-scale sequenc...

| 520 | |a Abstract Nitrous oxide ($ N_{2} $O) accumulation in biological nitrogen removal has drawn much attention in recent years; however, nitric oxide (NO) accumulation in denitrification was rarely studied. In this study, NO and $ N_{2} $O accumulation during nitrite denitrification in a lab-scale sequencing batch reactor (SBR) were investigated. Results showed that low pH (< 7) and high influent loading (> 360:90) (COD:$ NO_{2} $−-N) caused serious NO and $ N_{2} $O accumulation. The maximal NO accumulation of 4.96 mg $ L^{−1} $ was observed at influent loading of 720:180 and the maximal $ N_{2} $O accumulation of 46.29 mg $ L^{−1} $ was found at pH of 6. The NO accumulation was far higher than the values reported in previous studies. In addition, the high NO accumulation could completely inhibit the activities of reductases involved in denitrification. High NO and $ N_{2} $O accumulation were mainly caused by significant free nitrous acid (FNA) and NO inhibition at low pH and high influent loading. There were significant differences on NO and $ N_{2} $O accumulation at different carbon to nitrogen (COD/N). Low COD/N (≤ 4) could mitigate NO accumulation, but led to high $ N_{2} $O accumulation. It is speculated that NO accumulation is related to the rapid denitrification with accumulated electron in anaerobic stage at high COD/N. $ N_{2} $O accumulation is attributed to intense electron competition at low COD/N. High dissolved oxygen (DO) of 4.04 mg $ L^{−1} $ was detected during NO detoxification in this experiment, which is speculated to be partly caused by NO dismutation. | ||

In this study, NO and $ N_{2} $O accumulation during nitrite denitrification in a lab-scale sequencing batch reactor (SBR) were investigated. Results showed that low pH (< 7) and high influent loading (> 360:90) (COD:$ NO_{2} $−-N) caused serious NO and $ N_{2} $O accumulation. The maximal NO accumulation of 4.96 mg $ L^{−1} $ was observed at influent loading of 720:180 and the maximal $ N_{2} $O accumulation of 46.29 mg $ L^{−1} $ was found at pH of 6. The NO accumulation was far higher than the values reported in previous studies. In addition, the high NO accumulation could completely inhibit the activities of reductases involved in denitrification. High NO and $ N_{2} $O accumulation were mainly caused by significant free nitrous acid (FNA) and NO inhibition at low pH and high influent loading. There were significant differences on NO and $ N_{2} $O accumulation at different carbon to nitrogen (COD/N). Low COD/N (≤ 4) could mitigate NO accumulation, but led to high $ N_{2} $O accumulation. It is speculated that NO accumulation is related to the rapid denitrification with accumulated electron in anaerobic stage at high COD/N. $ N_{2} $O accumulation is attributed to intense electron competition at low COD/N.

In this study, NO and $ N_{2} $O accumulation during nitrite denitrification in a lab-scale sequencing batch reactor (SBR) were investigated. Results showed that low pH (< 7) and high influent loading (> 360:90) (COD:$ NO_{2} $−-N) caused serious NO and $ N_{2} $O accumulation. The maximal NO accumulation of 4.96 mg $ L^{−1} $ was observed at influent loading of 720:180 and the maximal $ N_{2} $O accumulation of 46.29 mg $ L^{−1} $ was found at pH of 6. The NO accumulation was far higher than the values reported in previous studies. In addition, the high NO accumulation could completely inhibit the activities of reductases involved in denitrification. High NO and $ N_{2} $O accumulation were mainly caused by significant free nitrous acid (FNA) and NO inhibition at low pH and high influent loading. There were significant differences on NO and $ N_{2} $O accumulation at different carbon to nitrogen (COD/N). Low COD/N (≤ 4) could mitigate NO accumulation, but led to high $ N_{2} $O accumulation. It is speculated that NO accumulation is related to the rapid denitrification with accumulated electron in anaerobic stage at high COD/N. $ N_{2} $O accumulation is attributed to intense electron competition at low COD/N. High dissolved oxygen (DO) of 4.04 mg $ L^{−1} $ was detected during NO detoxification in this experiment, which is speculated to be partly caused by NO dismutation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nitrite denitrification</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nitric oxide</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nitrous oxide</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">NO inhibition</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">NO dismutation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhao, Jianqiang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Huang, Ting</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Environmental science and pollution research</subfield><subfield code="d">Berlin : Springer, 1994</subfield><subfield code="g">26(2019), 33 vom: 21.

High NO and $ N_{2} $O accumulation during nitrite denitrification in lab-scale sequencing batch reactor: influencing factors and mechanism |
| abstract |
Abstract Nitrous oxide ($ N_{2} $O) accumulation in biological nitrogen removal has drawn much attention in recent years; however, nitric oxide (NO) accumulation in denitrification was rarely studied. In this study, NO and $ N_{2} $O accumulation during nitrite denitrification in a lab-scale sequencing batch reactor (SBR) were investigated. Results showed that low pH (< 7) and high influent loading (> 360:90) (COD:$ NO_{2} $−-N) caused serious NO and $ N_{2} $O accumulation. The maximal NO accumulation of 4.96 mg $ L^{−1} $ was observed at influent loading of 720:180 and the maximal $ N_{2} $O accumulation of 46.29 mg $ L^{−1} $ was found at pH of 6. The NO accumulation was far higher than the values reported in previous studies. In addition, the high NO accumulation could completely inhibit the activities of reductases involved in denitrification. High NO and $ N_{2} $O accumulation were mainly caused by significant free nitrous acid (FNA) and NO inhibition at low pH and high influent loading. There were significant differences on NO and $ N_{2} $O accumulation at different carbon to nitrogen (COD/N). Low COD/N (≤ 4) could mitigate NO accumulation, but led to high $ N_{2} $O accumulation. It is speculated that NO accumulation is related to the rapid denitrification with accumulated electron in anaerobic stage at high COD/N. $ N_{2} $O accumulation is attributed to intense electron competition at low COD/N. High dissolved oxygen (DO) of 4.04 mg $ L^{−1} $ was detected during NO detoxification in this experiment, which is speculated to be partly caused by NO dismutation. |

High dissolved oxygen (DO) of 4.04 mg $ L^{−1} $ was detected during NO detoxification in this experiment, which is speculated to be partly caused by NO dismutation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nitrite denitrification</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nitric oxide</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nitrous oxide</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">NO inhibition</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">NO dismutation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhao, Jianqiang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Huang, Ting</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Environmental science and pollution research</subfield><subfield code="d">Berlin : Springer, 1994</subfield><subfield code="g">26(2019), 33 vom: 21.
