Abstract :
The incorporation of enhanced biological phosphorus elimination in the single sludge process is a main challenge in the design of modern biological waste water treatment plants. We develop a mathematical model for estimating the influence of technical parameters such as the mean cell residence time, water and sludge recycle rate and possible intermediate feed or the influence of process configuration such as number mode, relation of size and interconnection of reactors. The model is based on the IAWRQ model No.1, and it describes the microkinetics of enhanced biological phosphorus elimination in addition to the degradation kinetics of carbonaceous components and nitrogen. The data from dynamic investigations such as daily patterns in flow and concentration shock loads or faults were compared with the predictions made by the dynamic model. An outline for the application of the developed complex model to waste water treatment plant is discussed
