Industrial circulating water treatment technology

Abstract

The invention discloses an industrial circulating water treatment technology which comprises the following steps: sterilizing, namely putting a sterilizing agent in circulating water for sterilization; chemically cleaning, namely putting a cleaning agent for chemical cleaning after the sterilization treatment is finished; chemically pre-filming, namely putting a chemical pre-filming agent after the chemical cleaning is finished. Thus, the sterilizing agent is put into the circulating water, the circulating water can carry the sterilizing agent to flow into a relevant pipeline to sterilize the pipeline, settlings attached on the pipeline can be stripped from the pipeline, settlings in the pipeline can be reduced; through chemical cleaning, the settlings and microorganisms in the pipeline can be further reduced, so that the settlings and the microorganisms in the pipeline can be cleaned; through chemical pre-filming, a protection film can be formed on the surface of the inner wall of the pipeline, so that the corrosion of the microorganisms and the settlings to the pipeline can be slowed down, the cleanness of the pipeline is ensured, and further the stable and efficient operation of a circulating system can be ensured.

Description

technical field [0001] The invention relates to the technical field of waste water reuse, in particular to an industrial circulating water treatment technology. Background technique [0002] With the increasing scarcity of water resources, in order to reduce the waste of water resources, most of the industrial water is now recycled water. The circulating water needs to be cooled during the circulation process. [0003] Since the circulating water cooling is usually open cooling, the cooling tower or cooling pool is placed outdoors, which causes dust and debris to enter the circulating water. Circulating water carrying debris circulates in the pipeline, and the debris will deposit in the pipeline, which will block the pipeline; at the same time, it is easy to breed bacteria in the pipeline. [0004] The deposition of debris and the growth of bacteria will cause corrosion of the pipeline, which will affect the heat transfer efficiency of the equipment and the service life of...

Problems solved by technology

[0003] Since the circulating water cooling is usually open cooling, the cooling tower or cooling pool is placed outdoors, which causes dust and debris to enter the circulating water

Circulating water with debris circulates in the pipeline, and the debris will deposit in the pipeline, which will block the pipeline; at the same time, it is easy to breed bacteria in the pipeline

[0004] The deposition of debris and the growth of bacteria will cause corrosion of the pipeline, which will affect the heat transfer efficiency of the equipment and the service life of the equipment. In severe cases, it will cause the entire industrial production to be shut down for maintenance
