Cl-与SO2-4土壤中硫酸盐还原菌对碳钢腐蚀的影响
Effects of Sulfate Reducing Bacteria on Corrosion of Carbon Steel in Cl- and SO2-4 Soils
摘 要
根据碳钢在分别添加了Cl－、SO2-4和Cl－+SO2-4的土壤中接菌与灭菌两种条件时的电化学阻抗谱特征,研究了硫酸盐还原菌(SRB)对碳钢腐蚀的影响.试验结果表明,三种盐分土壤中SRB均加速了碳钢的腐蚀速度.当Cl－灭菌土壤中添加SO2-4时,26天后碳钢腐蚀速度显著增加；当SO2-4灭菌土壤中添加Cl－时,碳钢腐蚀速度减小.

Abstract
The EIS characteristics of carbon steel in Cl-,SO2-4 and Cl-+SO2-4 soils with or without SRB were summarized.SRB could promote the corrosion rate of carbon steel in three kinds of soil.When SO2-4 was added to the soil containing Cl-,the corrosion rate of carbon steel increased greatly in the soil without SRB after 26 days.On the contrary,when Cl- was added to the soils contained SO2-4,the corrosion rate of carbon steel decreased obviously in the soil without SRB.
