Industrial circulating water treatment method

Abstract

The invention relates to an industrial circulating water treatment method. The method is characterized by comprising the following steps: step 1, filtering solid impurities and suspended solids from industrial circulating water through a filtering device; 2, adsorbing the filtered industrial circulating water through an adsorption device to remove organic matters; 3, conveying the industrial circulating water into a cooling device for cooling, and meanwhile supplementing water to the cooling device; 4, allowing the industrial circulating water to enter a crystallization desalting device, and enabling anions and cations in the water to separated out in the form of crystalline salt; and 5, allowing the industrial circulating water to enter a degerming device, conducting sterilizing and removing algae to obtain purified water. The problems that chemical agents need to be added to achieve the effects of scale prevention, corrosion prevention, sterilization and algae removal in the prior art are solved, cyclic utilization of industrial circulating water is achieved, zero pollution discharge is achieved, manual management is not needed, and equipment operation is automatically controlledthrough a control module.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a treatment method for industrial circulating water. Background technique [0002] The increasing shortage and pollution of fresh water resources have affected social development and the normal life of human beings. With the strengthening of environmental protection, the control of water resources is becoming more and more stringent, and water conservation and environmental protection discharge are becoming more and more urgent. Circulating cooling water agents generally use phosphorus-based formulas. Long-term use will cause phosphating and eutrophication of water resources, and the concentration of various harmful ions will increase. Although the discharged pollutants generally meet the discharge standards, the total pollutant discharge is huge , causing pollution of water resources and the environment.

AI Technical Summary

Problems solved by technology

Circulating cooling water agents generally use phosphorus-based formulas. Long-term use will cause phosphating and eutrophication of water resources, and the concentration of various harmful ions will increase. Although the discharged pollutants generally meet the discharge standards, the total pollutant discharge is huge , causing pollution of water resources and the environment

[0003] At present, the traditional circulating water anti-scaling, anti-corrosion, sterilization, and algae-killing generally adopt the treatment method of adding chemical agents. Cooling the circulating water requires a large amount of sewage discharge to maintain the balance of the total salt content in the circulating water and meet the requirements of anti-scaling and anti-corrosion; The chemicals added are all phosphorus-containing high-molecular organic chemicals, which are discharged with sewage, pollute water resources, and easily cause eutrophication of water resources
