A mathematical model of biological purification of wastewater from organic pollutants in the conditions of an
aeration tank with a fixed biocenosis (biofilm of microorganisms) is given. At the same time the peculiarities of the
formation and modeling of a complex stratified structure of a biofilm with variable processes and parameters and
are taken into account on in particular the processes of masstransfer and concentration of microorganisms along
its thickness are considered.
