The paper presents the results of work on the treatment of surface industrial and storm wastewater of PJSC "Transneft" using the reagent-ultrasonic method. As calculations and experiments have shown, an increase in the temperature of oil-contaminated effluent increases the degree of purification in the process of sedimentation by 13 %, in the process of pressure flotation by 18 %, and also reduces the time the effluent stays in the settling tank and flotation tank. The recovery of thermal energy from cooling the heat-loaded elements of the ultrasonic installation for heating the drain allows you to further increase the efficiency of the cleaning process. The obtained results simplify the hardware-technological scheme of treatment facilities and increase the energy and resource saving of the technologies used for treating surface runoff at the enterprise.
