[0002] A thermal power plant (thermal power plant) is a factory that uses combustibles such as coal, oil, and natural gas as fuel, converting chemical energy into heat energy through combustion, which then drives steam turbines or gas turbines to generate electricity. To protect the environment and achieve energy conservation and emission reduction, existing thermal power plants typically require wastewater and exhaust gas treatment. However, existing wastewater treatment systems, which rely on manual experience to adjust flue gas flow, have slow response times and suffer from significant scaling problems. The rapid scaling rate on tower walls necessitates shutdowns for cleaning every 72 hours with traditional equipment, leading to resource waste as metal resources cannot be recycled. Summary of the Invention

The purpose is to solve the problems of current wastewater treatment systems, which involve manual adjustment of flue gas volume based on experience, resulting in slow response speed, prominent scaling problems, rapid scaling rate on tower walls, and the need for shutdown for cleaning every 72 hours. Furthermore, the inability to recycle metal resources leads to resource waste.
