Abstract The processing of numerous experimental data shows that the high‐level and rough treatments of multicomponent sewage water follow different laws. In the case of rough treatment, the classical Monod's model is fairly adequate to the experiment. High concentrations of a pollutant “saturate” the complex of microorganisms (activated sludge or biofilm) and the general oxidation process follows a zero order for the substrate. In the case of high‐level treatment, the model of an n order ( n > 1) for the substrate is adequate to the experiment. Generalized models of aerobic treatment, independent of the reactor type (an aeration tank, trickling filter, rotating disk), are proposed.
