Pushkina Victoria Alexandrovna, Burlaka Svetlana Dmitrievna

The article examines the main factors of the negative impact on the hydrosphere of water resources on the territory of our country as a result of the functioning of Russian petrochemical enterprises. The author conducted a comparative analysis of the impact of industrial activities in the field of oil production and refining on sea and river water, conducted a practical study of the specifics of wastewater treatment depending on the industrial facilities where they are formed. The stages of the technological cycle are determined, at which the primary purification and then post-treatment of wastewater are carried out as efficiently as possible. In addition, attention is paid not only to the polluting effects of oil industry enterprises, but also to promising technologies for cleaning water bodies from oil and oil-containing pollutants. In the course of the research, the paper considers combinations of various cleaning methods, analyzes the effectiveness of technologies operating on the territory of various enterprises and suggests ways to maximize the efficiency of the cleaning process.

Keywords:oil production, combined purification methods, industrial wastewater, demulsification, oil stabilization, physico-chemical properties of the pollutant, filtration.
