Abstract
The problems caused by microbiologically influenced corrosion (MIC) have become increasingly prominent, which has caused very serious economic losses. The research on the mechanism and protective measures of MIC is becoming more and more important. In this paper, combined with the unique environment of the circulating water cooling system, the influence of the unique environmental factors of the system on MIC is analyzed. Several kinds of bacteria known to cause microbial corrosion are summarized, including sulfate-reducing bacteria, nitrate-reducing bacteria, iron oxidizing bacteria, etc. The current MIC mechanisms and related research progress are reviewed. Several common MIC monitoring methods are summarized. The commonly used protection methods and the ideas of MIC technologies in the recent stage are listed. Finally, the future research direction of the MIC is prospected.
