Water-saving and environment-friendly water treatment is the need of sustainable development

In order to control scale and corrosion of industrial circulating cooling water system, ensure the heat exchange efficiency and service life of equipment. There are many types of water treatment technologies. Among them, environmental protection and water-saving water treatment technology is more suitable for sustainable development and more popular among enterprises. To make industrial circulating cooling water treatment to advanced technology, to save water, accord with environmental protection needs, based on mature many years practical experience, put forward the design code of industrial circulating cooling water treatment, should add terms of water-saving environmental protection water treatment design, building, expanding or rebuilding project to apply and indirect heat exchange of the need of industrial circulating cooling water treatment, To meet the higher demand of water supply and drainage for water saving and environmental protection.

In the treatment of circulating cooling water, it is more important to solve the scaling and corrosion problems of heat exchange equipment. Scaling affects heat exchange efficiency, energy consumption and process operation. Corrosion reduces the service life of the device and poses safety hazards. In order to prevent scale formation and corrosion, phosphorous formula water treatment technology has been widely promoted in recent years, which effectively controls scale and corrosion. However, there are some problems that cannot be ignored:

First, phosphorus is a nutrient, which promotes the proliferation of bacteria, algae and microorganisms in the water system. Not only chlorination and various bactericidal and algaecidal agents are necessary, but also a large number of wastewater containing phosphorus and bactericidal and algaecidal agents are discharged, which aggravates the pollution of environmental waters and the degree of eutrophication and becomes a public hazard problem.

2. The residence time of phosphorus formula in the system is limited, which hydrolyzes into calcium phosphate scale, and the concentration ratio of circulating water is low, which is not conducive to water conservation.

Environmental protection and water saving water treatment technology, after years of practice and application, has a good effect of water saving and environmental protection. For example, LHE polymer has strong applicability to water with high alkalinity, high hardness, ammonia and alkali, or relatively poor water quality, high concentration rate, good inhibition effect of bacteria and algae, and no need to use fungicides. Therefore, in the new specification, the related technical conditions required by water-saving and environment-friendly water treatment design are specially added.

The suitable water-saving potions and technologies for environmental protection have been developed in the treatment of circulating cooling water in China, and through the long-term application practice, it provides a reference for the design of water-saving environmental protection for circulating cooling water. Due to the serious shortage of water resources in China, the demand and regulations of protecting environment are becoming increasingly strict. Therefore, the design of circulating cooling water should consider the use of water-saving and environmental protection technology as far as possible without affecting the process conditions.
