The ratio of CO2 and SO2 components and technological parameters have been experimentally established, which will ensure the absorption of carbon dioxide in the presence of sulfur dioxide and achieve an increase in the efficiency of cleaning industrial gas emissions and thereby increase the level of environmental safety of the atmosphere. The influence of such factors as temperature, light wavelength, and the presence of accompanying combustion gases on the dynamics of carbon dioxide absorption was studied. The optimal temperature at which the maximum growth of microalgae occurs in the studied system was determined. The energy of activation of the biochemical reaction of carbon dioxide binding in biomass (photosynthesis) under the studied conditions was determined. Its low value testifies to the expediency of using the process of photosynthesis to absorb carbon dioxide. Reverse, non-competitive inhibition by sulfur dioxide of the process of carbon dioxide absorption by microalgae has been proven, as well as the possibility of controlling the technology of cleaning industrial gas emissions by changing the amount of the substrate - carbon dioxide. Mathematical models of the investigated processes were developed and their solutions were obtained. Summarizing the research results, the basics of technological processes for cleaning industrial gas emissions from greenhouse gases with chlorophyll-containing microalgae, with subsequent biomethanization of the obtained biomass, were developed. The proposed technological scheme allows you to influence the reduction of the number of anthropogenic factors that cause climate change, which is the basis of modern environmentally safe technologies.
