Abstract

In the present paper aerobic granules were developed in a sequencing batch reactor SBR using synthetic wastewater and 81  of granular rate was obtained after 15day cultivation Aerobic granules have a 96  BOD removal to the wastewater and the reactor harbors a mount of biomass including bacteria fungi and protozoa In view of the complexity of kinetic behaviors of sludge and biological mechanisms of the granular SBR a cellular automata model was established to simulate the process of wastewater treatment The results indicate that the model not only visualized the complex adsorption and degradation process of aerobic granules but also well described the BOD removal of wastewater and microbial growth in the reactor Thus CA model is suitable for simulation of synthetic wastewater treatment This is the first report about dynamical and visual simulation of treatment process of synthetic wastewater in a granular SBR
