Temperature effect on aerobic denitrification and nitrification

Nitrogen loss without organic removal in biofilter was observed and its possible reason was explained. A lower hydraulic loading could improve aerobic denitrification rate. Aerobic denitrification was seriously affected by low temperature(below 10℃ ). However, nitrification rate remained high when t...

Beschreibung
Zusammenfassung:Nitrogen loss without organic removal in biofilter was observed and its possible reason was explained. A lower hydraulic loading could improve aerobic denitrification rate. Aerobic denitrification was seriously affected by low temperature(below 10℃ ). However, nitrification rate remained high when the temperature dropped from 15℃ to 5℃. It seemed the autotmphic biofilm in BAF could alleviate the adverse effect of low temperature.
