The main goal of this article is to design a multifactorial model for rapid evaluation of the effective operation of reactors for biological wastewater treatment, which is based on: changes in the concentration of organic pollutants in the bioreactor over time; changes in the concentration of activated sludge in the bioreactor over time; changes in the concentration of activated sludge in the reactor over time, taking into account the unevenness of the flow of wastewater to treatment facilities; the process of transporting the substrate to the bioreactor (it is possible to obtain different amounts at different times). The software implementation of the proposed algorithm for finding the appropriate model problem in the Python environment has been developed. The results of computer experiments on the study of the effectiveness of wastewater treatment in biological treatment reactors for different operating modes of the installations are given. The obtained results will be useful during calculations in the case of designing biological treatment facilities or during the reconstruction of existing bioreactors for their promising operation in new operating conditions.
