[0002] In order to strengthen the management and protection of water resources and promote the conservation and rational development and utilization of water resources, the state has further tightened the management and use of water resources, and has thoroughly implemented the concepts of green water use, efficient water use and water conservation. In order to improve water use efficiency, conserve water and meet water intake standards, the state has set limits on the water intake quotas of enterprises in water-scarce and arid areas in the north. Thermal power plants are large water users. In recent years, the construction of thermal power plants in northern China has adopted indirect air cooling on a large scale to cool the circulating water of thermal power plants in order to save costs and improve efficiency. The indirect cooling circulating water system consists of an aluminum radiator, a stainless steel condenser and a carbon steel pipe. Due to the presence of two materials, carbon steel and pure aluminum, which have large differences in electrochemical properties, higher requirements are placed on water quality. However, the intercooling circulating water quality indicators of many power plants are poor, with high iron content, high electrical conductivity, and abnormally high pH value.
