Background
Water is a basic condition for human survival and also a necessary condition for industrial production and development. With the rapid development of Chinese economy and the advance of modernization process, the industrial water consumption in China is increased from 500 hundred million m3 in 1980 to 2560 hundred million m3 in 2018. In industrial production, water is widely used as a cooling medium, and 70-80% of industrial water is used as cooling water. At present, the recycling rate of industrial water in China is low and is only less than 40%, and the recycling rate of industrial water in developed countries reaches 85%. Therefore, the method has important practical significance for researching the industrial water-saving problem, developing a new water-saving technology, improving the recycling rate of industrial water, reducing the industrial water consumption and saving the water cost of enterprises.
