Abstract
In the study the authors constructed mathematical models of wastewater treatment processes with Fenton’s reagent, ozone oxidative purification in the presence of a homogeneous catalyst, ozone oxidative purification in the presence of a heterogeneous catalyst, ozone oxidative purification in the presence of hydrogen peroxide — the Peroxon process. The resulting mathematical models allow the authors to predict the rate of chemical oxygen consumption (COD) at any time during the cleaning process, as well as to plan time expenditures to achieve the required level of this indicator. In addition, in the course of the research the integral coefficient of the models was calculated as a function of time, allowing to compare the cleaning processes and rank them by efficiency. As a result of the analysis of the integral coefficient, it was shown that the most effective is the oxidative purification of waste water with ozone in the presence of a homogeneous catalyst.
