The improvement of the utilization rate of the circulating water greatly slows down the water pressure, but reduces the discharge of the circulating water, improves the concentration multiple of the circulating water, and inevitably causes the problems of scaling, corrosion, mass breeding of microorganisms and the like of pipelines and equipment. At present, for an industrial circulating water treatment system, in order to reduce adverse effects on pipelines and equipment caused by concentration of salts and the like in circulating water, a method of adding chemical agents is generally used for keeping water quality stable so as to improve the concentration multiple of the circulating water system.
