Technical Field
[0001] This invention relates to the field of circulating water treatment technology, specifically an integrated industrial circulating water treatment system and process. Background Technology
[0002] As is well known, industries such as petroleum, coal, chemical, power generation, and municipal engineering all rely heavily on circulating cooling water systems. These systems are characterized by large circulating water volumes, high heat capacity, and simple cooling methods, offering the advantage of significant water conservation. However, this also brings some problems: corrosion, scaling, and biological sludge buildup occur in the systems, leading to increased salt and chloride ion content in the circulating water, as well as elevated bacterial levels. The harmful effects of these problems are well understood. To eliminate these adverse effects, water quality stabilization measures for the circulating water are necessary.
[0003] The existing circulating water treatment process does not include an oil separator, resulting in the presence of oil in the circulating water during operation. To solve this technical problem, an integrated industrial circulating water treatment system is proposed. Summary of the Invention

[0043] Based on the oil content data, it is determined whether the oil content in the circulating water exceeds the standard.

If it does, the circulating water is treated to ensure the quality of the circulating water.
