Abstract
The publication presents the results of an analysis of the dynamics of changes in surface water quality in the Lower Volga basin based on the processing of statistical data on monitoring the degree of pollution over a long period. Significant all-season excesses of the maximum permissible norms for the concentration in water of a whole spectrum of background and anthropogenic pollutants were recorded. Deficiencies in the implementation of existing methods have been identified that make it possible to assess the dynamics of changes in the state of the ecosystem of the water basin and select the most significant parameters for constructing a mathematical model for choosing the most effective wastewater treatment technology.The aim of this work is to select and evaluate the input parameters of a mathematical model, the implementation of which will ensure the search for optimal technology and appropriate technical means of surface wastewater treatment. This research is based on a comprehensive assessment of a wide range of hydrochemical indicators of pollution of discharged wastewater in controlled sites using statistical methods for processing observational data. The most significant parameters have been identified that allow the formation of a conceptual model, and the degree of their influence on the selection of optimal means and methods of wastewater treatment has been determined.
Highlights
The level of the ecological state of water resources in most of the territory of the Russian Federation is approaching a critical level

Summary
The level of the ecological state of water resources in most of the territory of the Russian Federation is approaching a critical level. One of the main reasons is the increase in the flow of polluting anthropogenic substances to surface sources with the extremely low efficiency of treatment facilities caused by the use of outdated technologies and technical means. The quality of surface runoff is determined by many simultaneously acting factors that can affect the sanitary condition and factors that affect the speed and meaning of the accumulated resources. Colloidal substances in wastewater have a particle size of 0.1 - 0.001 microns
