water recycling(circulating wateruse)A closed-loop water system composed of the water supply and drainage systems of a factory, workshop, or section. The water usage method of reusing the wastewater generated in the system after appropriate treatment, without adding or adding a small amount of fresh water, and without discharging or discharging less wastewater.

Industrial cooling water is used for cooling However, during the production of equipment and products, the temperature of the water increases, and its chemical properties do not change much. However, after the cooling water cools down and is reused for a long time, some solutes in the water concentrate, dust accumulates, and micro Biological growth can cause the deposition of scale in equipment pipelines or corrosion of metal equipment pipelines. Therefore, it is necessary to carry out water quality stabilization treatment to ensure the circulation of water systems Normal operation.

The circulating water system generally consists of the following parts:

①production process The heat exchanger in the middle;

②Cooling tower or cooling pool;

③Circulating water pump and collection tank.

exist In the context of increasingly scarce water resources, using a circulating cooling water system instead of direct flow cooling water(One use of water)The system gradually realizes closed-loop circulation of cooling water and continuously improves the reuse rate of water, which is the trend of industrial development in the future.industrial waste waterThe recycling and treatment of water quality are relatively complex, requiring special treatment processes, and the cost of treatment and reuse is relatively high High, it's better to promote the recycling of cooling water.
