ABSTRACT: 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.
