Mathematical modeling techniques of self-cleaning separate mechanisms, and also the models, which consider the impact of toxicants on the course of biological processes are offered. The functions reflecting a system reaction nature on internal and
external factors are received.
The obtained results qualitatively correctly describe the "biomass – resource" system evolution, which allows during comparison of model equations’ solutions and experimental data to calculate the kinetic constants of model.
