摘要：Research of water resources restoration of natural Dnieper river and man-made nature was carried out. The studies of water quality at working and peak operating modes of production cooling equipment were carried out. The conditions for the supersaturation of poorly soluble salts of the basin ( = 72.34; = 12.54) and accumulation of sediments of the reservoir are determined. The gravity tools for the restoration of water resources are proposed. A criterion equation for recharge the circulating system at peak mode was obtained. The granulometric potential of waste sediments at environmental feasibility is analyzed. The research involved supercritical temperature modes, taking into account precipitation hyperthermia. In the process of conducting a hydrological study, an evolutionary equation sediment model has been developed. The calculations of the technological flow capacity limits by of 125 W/m2 due to turbidity (750 mg/l) and hardness (up to 12 mg ekv per liter) of water resources are obtained. Mechanical sedimentation of the water stream increasing the energy potential up to 275 W/m2 was determined. The use of chemical agents (ozone) as a combined treatment increasing the flow potential up to 650 W/m2 is achieved. The application of technical way to natural water improving power to 975 W/m2 is received. Erosion of the bottom of the basin reduces the hydrological potential due to the unfinished state of biodegradation of sediments. The hydrological characteristics of the stream at a distance of 3000 m with characteristic technogenic inclusions were obtained. The study was conducted at natural Dnieper river and laboratory conditions with chemical catalyst and mechanical activator.
