摘要:

海泥中硫酸盐还原菌(Sulfate Reducing Bacteria, SRB)数量的变化会对其主要腐蚀环境因子产生影响。实验室条件下,在灭菌青岛海泥中加SRB菌种得到含SRB的海泥。在SRB的一个生长周期内,测量了由SRB数量变化引起的硫电位、银电位、pH值、氧化还原电位及电导率等主要腐蚀环境因子的变化,并找出了该变化的规律,探讨了通过腐蚀环境因子的变化测量SRB数量的可能性。

The change in corrosion parameter with SRB growth in sea mud

Abstract:

In this paper, the relation between the growth of SRB in sea mud and the main corrosion parameter has been studied. SRB was cultured and enriched in originated sea mud from Bohai gulf using culture medium in laboratory. Then, we can get various sea muds containing SRB of different concentrations. And our aim is to determine the changes of corrosion parameters with SRB growth and find rules of the changes by drawing figures.

Key words: sea mud Sulfate-Reducing Bacteria corrosion parameter
