In order to control the scaling and corrosion of industrial circulating cooling water system, the heat transfer efficiency and service life of the equipment are guaranteed. There are many kinds of water treatment technology. Among them, environmental protection water-saving water treatment technology is more adapted to the needs of sustainable development, but also more welcomed by enterprises. In order to make the industrial circulating cooling water treatment to achieve advanced technology, saving water, meet the needs of environmental protection, according to the years of accumulated mature practice experience, proposed in the design specification of the circulating cooling water in the water treatment industry, should be added in terms of water-saving and environment-friendly water treatment design, for construction, extension and renovation projects and indirect heat transfer in industrial circulating cooling water treatment needs to water-saving environmental protection higher demand for water supply and drainage. The most important thing is to solve the fouling and corrosion problems of heat exchange equipment. Fouling affects heat transfer efficiency, multi energy consumption, and affects process operation. Corrosion will reduce the service life of the equipment, and there are potential safety problems. In order to prevent fouling and corrosion, phosphorus formula water treatment technology has been popularized in recent years, which effectively controls scale and corrosion. However, phosphorus chemical agents should not
