Technical Field
The invention relates to the technical field of pipeline protection, in particular to a water treatment corrosion inhibitor.
Background
In a metal water supply pipeline, the attachment growth of microorganisms is unavoidable, the metabolic activities of aerobic iron bacteria and anaerobic sulfate reducing bacteria are mutually linked, the combined action generates the microbial corrosion of a biological film, and after the biological film is covered on the metal surface to be integrated, the interaction between the biological film and the metal surface can lead the pH value, dissolved oxygen, organic matter concentration, inorganic matter concentration and the like in the biological film to be completely different from the inner surface of the pipeline which is not covered with the biological film, so that the electrochemical corrosion is aggravated. In the pipeline, aerobic bacteria exist at the contact part of the pipe wall and water flow, and the outer side of the biological film is used for maintaining metabolic activity by means of dissolved oxygen of drinking water. Such species form precipitated corrosion products that, if deposited on the metal surface, form dead water regions within the deposit where dissolved oxygen is depleted, forming anaerobic regions where some anaerobic species can grow. Particularly in a closed circulating pipeline, the water flow speed is slower, the water changing period is long, and the biological film is difficult to strip by flushing of water flow, so that the biological film gradually grows into pieces to cover the inner surface.
The corrosion inhibitor is a better method for adding the corrosion inhibitor into water under the condition of not changing the material of the pipeline, and the corrosion inhibitor commonly used at present uses chlorine dioxide, quaternary ammonium salt, quaternary phosphonium salt and the like for sterilization, but in recent years, the environmental protection requirement is improved, and new requirements are made on the standard of the quality of discharged water, so that the environment-friendly and sterilizing water treatment corrosion inhibitor is needed.
