Effects of Aeration on Nitrogen and Phosphate Removal with A2O Process

Article Preview

Abstract:

A2O process is shortened form Anaerobic-Anoxic-Aerobic process, which can achieve carbon, nitrogen and phosphate removal, is widely used for its low cost and high efficiency. The Experiment using a 52.15 L anaerobic-anoxic- aerobic (A2O) reactor with simulate synthetic wastewater, by adjusting the aeration of Aerobic units, observing the performance of nitrogen and phosphorus removal under different dissolved oxygen(DO). The result of the whole operation show that the system can not keep a high TN removal efficiency under high aeration, and the low aeration made the system a significant decline in nitrogen and phosphorus removal.
