Effects of nitrite on phosphate uptake in anaerobic-oxic process

LI Jie, XIONG Biyong, ZHANG Shude, YANG Hong, ZHANG Jie

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 39-42 doi: 10.1007/s11783-007-0007-3

Abstract: An anaerobic-oxic (A/O) biological phosphorus removal reactor was operated to study the effect of nitriteThe results indicated that in addition to oxygen and nitrate (DPB, nitrate denitrifying phosphorus removal), to some extent, nitrite could also serve as an electron acceptor to achieve nitrite denitrifying phosphorusThe nitrite existing in the anoxic reactor made no difference to the quantity and rate of denitrifyingphosphorus removal, but it could reduce the consumption of nitrate.
