文摘

Nitrite accumulations were frequently observed at the sediment-water interface. The nitrate removal and nitrite accumulation are greatly affected by the addition of carbon. Carbon deficiency would result in electron competition and then nitrite accumulation. Excess carbon combined with extended HRTs has great potential to achieve ideal denitrification performances of an ecological treatment system.
