WAYS TO REDUCE POLLUTION OF SURFACE BODY CONTAINERS THROUGH IMPROVING THE METHOD OF WASTEWATER DISCHARGE USING THE EXAMPLE OF TREATMENT PLANTS IN LUTSK

Abstract

The study investigates the following: the current characteristics of methods for assessing the mixing of return waters in rivers; the specific features of modern collection and treatment of return waters entering the municipal wastewater treatment facilities in the city of Lutsk; the impact of wastewater discharge on the qualitative characteristics of the Styr River in the area of return water discharge in Lutsk; and the identification of possible alternative options for wastewater discharge from the municipal treatment facilities in Lutsk to reduce river pollution. The research analyzed the factors significantly affecting the dilution and mixing processes of treated wastewater after discharge into the Styr River and identified their key features.   The findings indicate that improving the hydro-ecological state of the Styr River in the area of Lutsk wastewater treatment facilities can be achieved without significantly enhancing the efficiency of wastewater treatment. This can be accomplished by implementing more effective methods of wastewater discharge and mixing with the river water through modern outfall structures. The study proposes improving the conditions for wastewater dilution by potentially replacing the shoreline outfall with an in-stream outfall to prevent excessive water pollution under adverse conditions.
