Simulation and Optimization of Denitrifying Phosphorus Removal in A2/O
The GPS-X was used to simulate the denitrifying phosphorus removal in the A2/O.The improvement actions were obtained due to the simulation result.Moreover, the effect of denitrifying phosphorus removal was forecasted after the application of optimization and improvement. The prediction shows that: by adjusting the operating parameters such as SRT was adjusted to 15ds, the internal reflux ratio was adjusted to 300% and the external reflux ratio was adjusted to 100%,the denitrifying phosphorus removal in the A2/O was obviously increased. Therefore, the employment of GPS-X software in simulation and optimization can provide guidance for the operation and control in wastewater treatment plants.
