“…Thus, the zone of the hydrogenic influence of the reservoir began to be understood as the territory of the coasts, which is under its direct or indirect human influence. The effect of "blooming" of water bodies is due to a significant supply of nitrogen, phosphorus-containing chemical compounds, which are a nutrient medium for cyanogenous algae [7,8]. As a result of intensive processes of eutrophication in the reservoir, the littoral zone began to shrink, the habitat of aquatic organisms deteriorated, the food supply decreased, and the area of freezing zones increased [9].…”

The article deals with the installation of nature-like technologies in natural reservoirs exposed to high anthropogenic load. Water resources and the changes occurring in them are studied by various scientific schools, but still, the main task is to determine the processes that maintain the homeostasis of the biosphere and which cause irreversible damage. Functional ecotones formed in the coastal water intake zones of water bodies are of particular interest. Since the prevalence of water-natural ecotones is very significant, the study of border biotic communities with the mechanism of fluctuation activity and continuity of biogeocenotic environments requires new technologies for biosphere monitoring. The results of studying the water area of the Tsimlyansk reservoir, located in the South of Russia, undergoing exogenous eutrophication, are shown. The surface layer of the reservoir, heated and enriched with organic and mineral substances, creates favorable conditions for the vital activity of problem biogens, which cause the rapid development of blue-green algae, creating the “blooming effect” of water. The degradation of the fishery Tsimlyansk reservoir with unique natural complexes can be stopped by the algolization technology developed at the All-Russian Research Institute of Irrigated Agriculture. Biological reclamation, the introduction of Chlorella vulgaris into the bays of the Tsimlyansk reservoir, makes it possible to improve the sanitary and hygienic indicators of water, improve the species composition of biological resources, and reduce the “blooming effect”.

“…The average annual productivity of this type unit will be 72 t/ha (in dry weight) per year with average daily production of 20 g/m 2 and duration of vegetation period of 6 months (Mel'nikov and Shalygo 2009); -Microalgae have a higher yield compared to higher plants. Yield is more than 30-50 tons of dry mass from 1 hectare of water surface with a water layer thickness of 10-15 cm for 7 months of cultivation in open pools (Abdulagatov et al 2018). -Cultivation of algae does not require agricultural resourcesland and freshwater, alienation of large areas for cultivation of food crops.…”

Bioenergy is energy derived from the transformation of solid, liquid, and gaseous products derived from biomass. According to the National Reporting to the United Nations Framework Convention on Climate Change, which follows the Intergovernmental Panel on Climate Change guidelines, "total CO 2 emissions" is defined. CO 2 emissions/removals from land use, land-use change, and forestry are often known with much less confidence than emissions in other sectors. In such cases, "total" emissions may be calculated as the sum of emissions for the energy, industrial processes, agriculture, and waste sectors (Total CO 2 emissions. Retrieved April 15, 2020, from the United Nations site for the MDG Indicators https://millenniumindicators.un.org/unsd/mdg/ Metadata.aspx?IndicatorId¼0&SeriesId¼750). Greenhouse gas emissions from the combustion of fossil fuels appear to be linked to the warming of the land in greenhouses. In principle, it is possible to remove carbon dioxide from point sources such as oil production or power plants and then liquefy CO 2 and inject it into underground aquifers. Deposition/removal of carbon dioxide are processes of its fixation/binding in a form that will not be freely available in the atmosphere and other gas streams. Introduction. The Environmental Challenges of Carbon Dioxide Utilization at Thermal Power Plants The long-term challenge for the energy sector is to achieve near-total decarbonization by 2050 to ensure that climate change objectives are met. Based on the existing fossil fuel infrastructure, coal and gas will continue to play a significant role in electricity generation. The processes of reducing carbon levels in coal and gas are largely due to the introduction of measures to capture (before or after fuel combustion), transport, and long-term storage of carbon contained in these fuels. According to experts of the Intergovernmental Panel on Climate Change under the IEA, in 25 EU countries, about 31% of all energy is produced from coal. The coal-fired thermal power plants (TPPs) generate the majority of the electricity and produce the highest rate of CO 2 per kilowatt-hour (Moazzem et al. 2012). Besides, lignite is widely used in Europe. Under such conditions, according to "An overview

Currently, the search for the use of environmentally friendly and digital technologies is underway [4,5].

“…Anaerobic decay of dead organisms in the bottom soil is accompanied by the release of strong toxic substances: methane, hydrogen sulfide, phenol. With the massive development of phytoplankton, especially blue-green algae, self-pollution of the reservoir occurs, dying off and subsequent decomposition causes a violation of the oxygen regime of water bodies, leading to the death of fish [5]. The most toxic are blue-green algae of the genera: Microcystis aeruginosa, Anabaena flos-aqae, Aphanizomenon flos-aqae, Oscillatoria aqardhii.…”

The article raises questions of anthropogenic impact on continental water bodies. The results of expeditionary studies to increase the potential of microalgae in the improvement of the Tsimlyansk reservoir, created on the Don River on the basis of the use of biological reclamation - algolization, are presented. The reasons for the deterioration of water quality in the reservoir are determined, which are associated with the intensive introduction of pollutants and hydrometeorological conditions that contribute to the intensive development of phytoplankton in the summer-autumn period. At the end of May, the water column warms up rather quickly (+20° C), phytoplankton begins to multiply strongly, the number reaches - 20.5 million cells/l, biomass 15.5 g/m3. The most active are blue-green algae of the genus Anabaena. In July-August, a prolonged increase in water temperature up to 25-27°C contributes to an increase in phytoplankton of blue-green algae of the genera Aphanizomenon, Microcystis, Oscillatoria. Blue-green algae, creating the effect of “blooming” of water, form large colonies and dominate over other types of microorganisms. Thanks to the developments of scientists, it became possible to use biological reclamation in the restoration of ecosystems of natural and artificial reservoirs. Algolization - the introduction of microalgae Chlorella vulgaris into water bodies, allows to improve the quality of water in terms of gas composition, content of organic substances and reduce the effect of water “blooming”.
