description A dynamical model describing the biological wastewater treatment process, taking into account the variability of the activated sludge biomass structure, is proposed. Where biomass turnover time is short, fast-growing microorganisms, consuming easily oxidizable substances, prevail in activated sludge. In such conditions, slowgrowing microorganisms, consuming poorly digestible substances, do not get enough<br />time to become part of the biomass. As a result, such substances are discharged undecomposed. If the biomass turnover time is sufficiently large, then slow-growing<br />microorganisms get established in the digester, augmenting the diversity of species. A method of dynamical decomposition developed by one of the authors is applied to model the above phenomenon. This method permits to represent the process as<br />a sequence of relatively simple models which follow one another according to the conditions of process behavior. A method for stabilization of the biological treatment process has been developed.
