摘要
在油田注水系统和工业循环冷却水系统中 ,硫酸盐还原菌 (SRB)是微生物腐蚀 (MIC)的主要因素之一。硫酸盐还原菌对金属的腐蚀主要表现在SRB的生长代谢在金属表面形成生物膜 ,改变了生物膜内微环境 ,其代谢产物与金属基体相互作用 ,加速了金属的腐蚀过程。从硫酸盐还原菌的微生物生理学 ,SRB的腐蚀机理 ,SRB对材料的腐蚀 ,SRB腐蚀研究方法和SRB腐蚀防治等几个方面 ,对微生物腐蚀的近期研究状况进行综述 ,并展望了微生物腐蚀研究的近期发展趋势。
Sulfate reducing bacteria(SRB) is one of the most important microorganisms in microbiologically influenced corrosion(M IC) in oil field water injection system and cycle cooling water system in indust ry. The harms of SRB corrosion have received much attention in the latest twenty years. The SRB corrosion is characterized by formation of biofilms on metal sur faces, which have changed the corrosion conditions such as pH value, dissolved o xygen,chemical species and contents. The metabolite of SRB interacted with metal substrate and accelerated the corrosion of metal and alloy. The paper covers th e following topics: microbiological physidogy, SRB corrosion mechanism, SRB corr osion on different materials, measuring methods and control of SRB corrosion. Re cent advances on MIC and the trends were introduced.
