Influence of Phosphorus Release and Initial Nitrate Concentration on Anoxic Phosphorus Uptake

W. Xu, W. Qin, Z. Shao, and T. Fan
Abstract—Denitrifying phosphorus removal technology has advantage on beneficial for reduction of COD consumption, and the anoxic phosphorus uptake process is the key process. This study was to investigate the effect of the phosphorus release and initial nitrate concentration, which are two important infectors, on the anoxic phosphorus uptake process, by batch two Tests. The results show that the improvement of Prelease/MLSS would increase the amount of nitrogen and phosphorus removal as well as the specific phosphorus uptake rate(PUR),and the relationship between the amount of P release per MLSS was found in this paper. Nitrate would have little impact on the phosphorus uptake rate in anoxic condition if nitrate was adequate as the electron acceptor. Besides, a function formula was fitted to predict the amount of electron acceptor by the amount of P release per MLSS.

Index Terms—Wastewater treatment, denitrification and phosphorus removal, anoxic phosphorus uptake.
