Wastewater Treatment of the Thermal Power Plants for Desulfurization of Flue Gas

The article presents technology by Kazakhstani scientists to reduce volume of sulfur oxides emission reductionfrom flue gases of thermal power plants by treatment of wastewater. Highly mineralized wastewater to be processed with water treatment equipment using ion exchange method, including N cation and N anion filters, as well as wastewater from drum boilers with a pH value of 11.5-12.The draft of the technological solution, including a thermal-mechanical circuit, an environmental impact assessment section, a process automatic control circuit and an equipment power supply scheme has been developed. The project is under independent examination now. The introduction of flue gas desulfurization technology through wastewater treatment is planned at the thermal power plant of the capital of the Republic of Kazakhstan in 2020. The developed technical solutions will allow increasing the degree of sulfur oxide collection efficiency from 12% to 48%. © 2020 School of Science, IHU. All Rights Reserved.
