Анотація


To simulate the process of biological wastewater treatment in aeration tank numerical model was developed.  The flow field in the aeration tank is simulated on the basis of potential flow model.  2-D transport equations are used to simulate substrate and sludge dispersion in aeration tank. To simulate the process of biological treatment a simplified model is used which takes into account the process of sludge growth and substrate extinction. For the numerical integration of transport equations implicit difference scheme was used.
