1、At present，Activated sludge model has great value and call be used to improvethe study，design and optimum operation ofwastewater treatment around the world．It has been applied widely in the world． In this thesis，the

2、application and calibration of Activated Sludge Model No．I inthe practical wastewater treatment plant had been implemented．The characterization and parameter of the outfluent from the rotational flow grit chamber had bee

3、n 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

4、analyses the problems existin 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 Call is practicaL
