The Study of Operation and Dynamic on the Modified A2 / O Process
Abstract:
Based on recent experimental data in the Guangrao Wastewater Treatment Plant, the performance and dynamics of modified A2 / O process was summarized. The results shows that: the average removal rate of COD is 73.7%, and COD is mainly removed in pre-anoxic pool; the average removal rate of TN is 64.2%, and TN is mainly removed in pre-anoxic and aerobic pool; the average removal rate of TP is 79.48%, and phosphorus release happens in the pre-anoxic pool and phosphorus uptake happens in anoxic and aerobic pools. Based on the material balance and the results, the dynamic equation of degradation for pollutants in each stage is established, and the predicted and actual values are compared, the results show that the dynamic equations are fit for the Guangrao Wastewater Treatment Plant.
