METHOD OF CONTROLLING BIOLOGICAL CONTAMINATION OF WATER BASIS IN ACTING WATER POWER DEVELOPMENTS OF HYDROELECTRIC POWER STATIONS

摘要

The invention relates to the protection of waters from biological pollution, in particular, to methods for reducing the content of blue-green algae, pathogens of water "blooming" in hydroelectric power plants, and improving the sanitary-biological situation. The purpose of the invention is to increase efficiency. It is recommended to carry out periodic mixing of water in the upper reservoir by reversing the direction of water flow in its near-bottom horizon from the lower reach upward. The change is made by switching the operation of the units of the hydroelectric power station from the turbine to the pump-motor mode at night by 2-8 hours. 2 s.p. f-ly, 3 tab.
