Description

Technical Field

[0001] The utility model relates to the technical field of circulating water treatment, in particular to a circulating water ternary purification treatment system. Background Art

[0002] Water is often used as a cooling medium in industrial production. In order to save water resources, water exchanges heat through a heat exchanger and is cooled by a cooling tower before being recycled. After the water is recycled, it evaporates and concentrates continuously due to heat exchange, and the various ions in the water become more and more concentrated, causing calcium and magnesium ions in the water to precipitate and form scale, affecting the heat exchange effect; and the circulating water temperature is generally between 32℃ and 37℃, which is most suitable for the growth of bacteria and algae. Bacteria, algae and slime not only affect the heat exchange effect of the equipment, but also easily clog the pipeline and affect production; the cooling water is recycled for a long time, is continuously concentrated and affected by air pollution, resulting in deterioration of water quality and strong corrosiveness, posing a corrosion risk to the equipment.

[0003] In the prior art, three water treatment technologies are usually used: physical water treatment, chemical water treatment, and biochemical water treatment. Different methods have different effects on water quality. The actual use effect of chemical water treatment methods is poor, and scaling and algae will still occur. Chemical cleaning is also required, and a large amount of drainage is required, resulting in a waste of water resources. At the same time, the sewage is rich in chemical agents, which pollutes the ecological environment. Physical water treatment technology mainly uses magnetic treatment technology, electrostatic water treatment technology, and alloy water treatment technology. Existing physical water treatment devices can play a certain role in water treatment, but they cannot solve the problems caused by circulating water when used alone. At the same time, existing physical water treatment devices can purify water quality, but they cannot solve the problems of scaling, corrosion, algae growth, and difficulty in descaling of water treatment devices after water recycling.
