Research of Denitrifying Dephosphatation in A₂ON Process

Abstract:

In order to investigate the potential of sequencing batch biofilm reactor (SBBR) technology of two-sludge system for denitrifying dephosphatation (A₂ON process),we build a tab-scale experiment .Then find that the simultaneous removal of phosphorus and nitrogen in the two sludge system is possible .By the control of COD/TN ratio ,highly effective simultaneous nitrification and denitrification is achieved in the A2ON system.And the ratio of denitrification is 85%, the ratio of dephosphatation is 87%.It also demonstrates that the process is stable ,at the same time decrease the effect of dephosphorization and denitrification by the limited carbon source.
