Description

technical field [0001] The invention relates to the technical field of industrial circulating water treatment, in particular to an overall industrial circulating water treatment system and process. Background technique [0002] As we all know, petroleum, coal, chemical industry, power generation, municipal and other industries cannot do without circulating cooling water system, which is characterized by large circulating water volume, high heat capacity, simple cooling means, and the advantage of saving a lot of water resources. But it also brings some problems, that is, the system will produce corrosion, scaling and biological slime, the content of salt and chloride ion in the circulating water will increase, and the content of bacteria will increase. The harm caused by it has been very clear. In order to eliminate these adverse effects, it is necessary to stabilize the water quality of circulating water. [0003] The basic chemical method for the treatment of circulating ...
