LABORATORY STUDY ON THE SEDIMENTATION OF SURFACE WASTEWATER POLLUTANT COMPONENTS IN HISTORICAL PART OF SAMARA

The article discusses the existing drainage systems in Samara, the proposed project for the reconstruction of storm collector outlets located within the boundaries of the historical part of Samara. One of the factors of reservoir pollution (of Volga and Samara rivers) is untreated surface wastewater. The article specifies the outlets in the historical part of the city pernicious for the water reservoir. The study on the sedimentation of pollutant components contained in surface wastewater disposed from the historical part of Samara was held. As a result of the research, it was found that due to treatment facilities and storage tanks construction, as well as wastewater pumping into the household sewerage system, surface wastewater pumping will reduce the anthropogenic impact on the reservoir. It will also contribute to some extent to household waste dilution and increase the hydraulic load on urban sewage treatment plants. The water bodies of the water area of Samara are experiencing anthropogenic pressure, including due to untreated surface wastewater. The qualitative indicators of surface wastewater of a large industrial center have been studied on the example of the urban district of Samara. A list of negative indicators for water bodies has been determined; their maximal, average and minimal value ranges have been specified. It was revealed that the presented data will not have a negative impact on the centralized water disposal systems of settlements and urban districts.
