In this work, the processes of self-purification of natural water masses have been studied, and the possibility of laboratory modeling based on the obtained coefficient of the rate of self-purification of water K from pollutants has been investigated. The correlation between the phenol content and the physical factors of the selected sample was investigated. The calculation of the rate coefficient of self-purification of river water from a contaminant is carried out. The physico-chemical composition of surface waters directly depends on the hydrological regime of the river, which means that the model of self-purification processes can be applied under certain parameters of the studied rivers. On the model obtained during these works, various studies of the correlation of the physico-chemical composition of water from various hydrological parameters can be carried out. The basis of this study was the work of Soviet scientists in the field of mathematical modeling of physico-chemical processes in the natural environment of surface waters.
