Abstract

SBR experiments were performed by a sequence of anaerobic/anoxic/ aerobic. The effect of various types and concentrations of electron acceptor on anoxic phosphorus uptake were investigated in detail to obtain a better insight into the behavior of phosphateaccumulating organisms(PAOs) and denitrifying phosphateaccumulating organisms(DNPAOs).Results of experimental investigations are presented, strongly supporting the hypothesis that PAOs from activated sludge systems consist of two groups:DNPAOs which can use either oxygen or nitrate as the final electron acceptor and nonDNPAOs which can use only oxygen and giving the characteristics of phosphorus uptake rate during the anaerobic/anoxic/aerobic period.
