Operation and Optimization of an Alternating Oxic-Anoxic Shortcut Nitrification-Denitrification System

Abstract:

A novel alternating oxic-anoxic operation mode of shortcut nitrification-denitrification was developed in a sequencing batch reactor at ambient temperature. Operational parameters favorable for maintaining the shortcut nitrification-denitrification were investigated and optimized. The experiments showed that alternating oxic-anoxic shortcut nitrification-denitrification system was able to be an independent treatment process in domestic wastewater treatment. And the optimization approach was so efficient that the main pollutant discharge targets achieved Standard A of the first class in "Discharge standard of pollutants for municipal wastewater treatment plant". Moreover, the reliability of the operation strategy in this experimentation was proved, which indicated the excellent nitrogen removal performances.
