Vidnovluvana energetikaРезюме: | The accumulation of excess and technological heat in the upper aquifers leads to thermal and bacterial contamination of the horizons. The article presents the results of experimental research on bacteriological changes in aquifers as a result of an increase in their temperature. The research was carried out on the basis of the analysis of groundwater samples of the Poltava aquifer from production wells located at the experimental training ground of the National Academy of Sciences of the National Academy of Sciences. The chemical and bacteriological composition of waters and the degree of their natural pollution were determined. Groundwater belongs to the group of poorly mineralized hydrocarbonate calcium-magnesium waters with an average mineralization of 495.86 mg/dm3 and is slightly contaminated with mesophilic bacteria. In the laboratory of the Center for Preventive Medicine of the State Administration of Affairs, analyzes were carried out that allow simulating the behavior of bacteria depending on the increase in the temperature of underground water in the horizon. It was established that an increase in the temperature of water in the aquifer in the temperature range of 20-40 °C leads to an increase in the number of bacteria by 30-40 times. The obtained results indicate the need to anticipate the use of bacteriological cleaning methods in the creation of underground heat storage systems. |
