Abstract: In this study, Activated Sludge Model No.1 (ASM1) was used for modelling of wastewater treatment plant. The operational data of municipal wastewater treatment plant (WWTP) were collected and treated. Experimental data and biological treatment technology were structured according to the mathematical model requirements. They were implemented into computer scheme of the plant. Very good agreement between the experimental and calculated MLSS and effluent concentrations of the monitored pollution indicators was obtained after calibration of the model. The calibrated model was used to analyze the influence of oxygen concentration in the reactor and the influence of the prepared substitution of anaerobic sludge stabilization by aerobic technology on effluent quality. Changes of oxygen concentration significantly influenced the effluent values of ammonium nitrogen and nitrate nitrogen. Considerable increase of MLSS resulted from dynamic simulations performed for biological treatment with aerobic sludge stabilization. In both cases the results of dynamic simulation indicate that the WWTP will comply with the effluent standard values.
