Abstract：According to completely mixed features of Carrousel oxidation ditch,this paper puts forward an idea which divides it into several series reactors of aeration completely mixed reaction of aeration and non aeration.Moreover,based on ASM3 mechanism model,the article builds a physical model on WEST software platform.Taking advantage of the WEST simulation software,a steady simulation was done to the established model.It had been proved that according to the analysis of its process features and DO changes along the characteristics,Carrousel oxidation ditch whose dealing ability may reach 12,000 tons per day contains oxic zone and anoxic zone and can be divided into 15 sections averagely in accordance with the length of pools.The length of each section is 13.2 m,the width 4.5,the area 56.87 m2.Among the 15 sections,the first 4 areas are the anoxic zone,the following 11 sections are the aerobic zone.Via steady simulation,this modeling can show the treatment process and treatment efficiency in sewage treatment plant.It laid a foundation for subsequent research of dynamic simulation,optimization of model and parameter estimation.
