Abstract	At present, activated sludge model has great value and can be used to improve the study,design and optimum operation of wastewater treatment around the world. It has been applied widely in the world.In this paper,the application and calibration of Activated Sludge Model No.l in the practical wastewater treatment plant had been implemented. The characterization and parameter of the outfluent from the rotational flow grit chamber had been measured in the WWTP. The actual operation procedure is simulated in case of both steady and dynamic status using simulation software named as WEST, which is from DHI. Where after different simulation analysis is done to analyses the problems exist in this factory, and hence based on the analysis result, the optimized suggestion is arised.The result shows that the method of characterization and parameter in this paper can is practical. The heterotrophic yield coefficient YH, Heterotrophic max specific growth rateµmax, heterotrophic decay rate bH, readily biodegradable substrate Ss and slowly biodegradable substrate XS could be characterized by the method of batch OUR respirometric experiments which is simple to calculate, and especially the outcome date is stable.The WEST software was used to simulate the real operation of the WWTP,the result shows that using the combination of test mensuration and model calibration, good simulation results were achieved though changing of the model parameters.The activated sludge model which was promoted by the IAWQ can be used as a useful tool in operation management, technical improvement and scientific research in WWTPs. Nevertheless WEST software which was based on the activated sludge model could simulate the performance of activated sludge process and provide valuable advices for directing WWTPs.
