Abstract
One of the frequently encountered problems of power plant small cooling ponds is rapid eutrophication and related intensified development of phytoplankton (“hyperflow”) and overgrowing of ponds by higher aquatic vegetation. As a result of hyper-flowering, an enormous amount of detritus settles on the condenser tubes, reducing the efficiency of the power plant operation. The development of higher aquatic vegetation contributes to the appearing of the shoals. As a result the volume, area and other characteristics of the cooling ponds are getting changed. The article describes the environmental problems of small manmade ponds of power plants and coal mines in mining regions. Two approaches to the problem of eutrophication are considered: technological and ecological. The negative effects of herbicides application to aquatic organisms are experimentally proved. An ecological approach to solving the problem by fish-land reclamation method is shown.
Highlights
Today the correlation between different factors of sustainable development – socioeconomic and ecological development of old industrial regions is in focus of many Russian researches [1-4]
We considered the situation that developed in the cooling pond of Belovskaya power plant (Belovskoe reservoir)
All the data given indicate that a mesotrophic-eutrophic ecosystem has developed in the Belovskaya power plant cooling pond
Summary
Today the correlation between different factors of sustainable development – socioeconomic and ecological development of old industrial regions is in focus of many Russian researches [1-4]. Studies of a number of scientists, including V.V. Kirillov et al allowed to assess the level of production and destruction processes in the cooling pond of Belovskaya power plant, to estimaye the current state of zoobenthos and zooperifiton and higher aquatic vegetation of the pond and compare the obtained data with the results of other authors [16-21].
