【 摘 要 】

Subject: the results of the analysis of the dynamics of changes in the quality of surface waters in the Lower Volga basin are presented based on the processing of statistical data on the long-term monitoring of their contamination degree. Significant all-season excesses of the maximum permissible values for the concentration of a whole range of background and anthropogenic pollutants in water were recorded. We identified the shortcomings of implementation of the existing methods that allow us to assess the dynamics of the state of the water basin ecosystem and choose the most essential parameters for constructing a mathematical model of selection of the most effective wastewater treatment technology. Research objectives: selection and evaluation of the input parameters of the mathematical model, the implementation of which will ensure the search for the optimal technology and appropriate technical solutions for cleaning surface sewage. Materials and methods: the conducted study is based on a comprehensive assessment of a wide range of hydro-chemical indicators of contamination of discharged wastewater in controlled locations using statistical methods for processing experimental data. Results: we identified the most essential parameters that allow us to form a conceptual model, and we determined the degree of their influence on the selection of the optimal solutions and methods of wastewater treatment. Conclusions: conclusions obtained during the study indicate the need for creation of a mathematical model of assessment of the quality of surface sewage treatment in urbanized areas for improvement of technological parameters of treatment facilities.
