Abstract

Abstract

Based on the A²/O process of a sewage plant in Shenzhen and its on-line monitoring data of influent and effluent, the A²/O simulation model was established and corrected by using GPS-X. The reliability of the model was demonstrated. Two impact simulation schemes, continuous impact simulation and random impact simulation, were proposed to simulate two ways of low B/C sewage impact on A²/O process due to the increase of proportion of dissolved inert component (frsi) in total COD. Simulation results showed that TN, TP and COD concentration of effluent exceeded the standard in turn when A²/O was impacted by low B/C sewage, and adding carbon source could reduce the exceeding rate of TN and TP. Reducing the dissolved oxygen concentration in aerobic tank could save carbon source dosage and the minimum exceeding rate of TN and TP was less than COD. When taking the over-standard rate of COD of 5% during the simulation time as the threshold, A²/O process could withstand the continuous impact of sewage with frsi=0.133 and B/C=0.332 for 31 days, or the random impact of sewage with frsi=0.136 and B/C=0.330 for 25 days, sewage with frsi=0.143 and B/C=0.328 for 20 days, sewage with frsi=0.151 and B/C=0.324 for 15 days, sewage with frsi=0.161 and B/C=0.319 for 10 days, and sewage with frsi=0.189 and B/C=0.308 for 5 days, namely.
- low B/C,
- GPS-X,
- simulation,
