Surface runoff treatment from urban territories and adjacent railway utility lines

Summary

Surface runoff has been one of the main pollutants of the environment alongside with domestic and industrial wastewater. Surface runoff constituting filtrate from railway bed is highly toxic and shall be subject to special decontamination before discharge into water bodies. The studies are aiming at the development and selection of the optimal method from the point of efficiency, cost effectiveness and ease of using the technology of surface runoff treatment from residential territories of Samara and adjacent railway. The problems of purification of surface runoff from railway bed and adjacent residential territories of Samara are considered through the example of discharge into the Depovskii gully. During the study samples of wastewater were taken and analyzed to estimate the composition of pollution. Basing on the analysis results several options of surface runoff treatment with the use of different technologies are considered. The improved process flow scheme that provides for 85–90% efficiency of surface runoff treatment is proposed provided its implementation is economically feasible. The given technology shall be implemented with its upgrade to complete purification.
