Abstract
A simulation model for changes of phosphorus and organic carbon concentration in a cycle period on biological phosphorus removal is developed in this study. We propose a model based on a simple combination of two species of biomass, based on its phosphorus content. Changes of phosphorus and organic carbon concentrations under anaerobic/aerobic condition are simulated and estimated for the effects of organic carbon loading, the ratio of phosphorus accumulating biomass to total biomass, biomass concentration and the maximum specific growth rate.
Phosphorus release/uptake in the biomass during a cycle period could basically be attained by controlling of orgaic carbon concentration and the ratio of phosphorus accumulating biomass to total biomass.
The prediction of profiles of phosphorus and organic carbon concentrations in the reactor gives fair agreement with the experiment results.
