摘要:

采用数值仿真与实验相结合研究了流体冲刷下SRB的腐蚀行为。基于计算流体动力学 (CFD) 得到的管道腐蚀区域预测云图和粒子运动轨迹图结果，预判管道腐蚀部位，结果表明管道底部较顶部腐蚀、管道出口处腐蚀较入口处严重；在预判管道腐蚀部位布置研究电极，运用电化学方法以及表面分析方法探究了流体冲刷下SRB的腐蚀规律。结果表明，SRB在金属表面未形成生物膜时 (未进行预膜处理)，冲刷腐蚀占主导地位，金属表面有明显的冲刷腐蚀特点，腐蚀产物主要以Fe的氧化物为主。当SRB在金属表面预先形成致密生物膜时(进行预膜处理)，SRB腐蚀占主导地位，生物膜会减缓冲刷腐蚀，但膜下SRB的生命活动会与金属基体发生电子交换，从而发生SRB腐蚀，腐蚀产物主要以硫铁化合物为主。

Abstract：

Erosion corrosion and sulfate reducing bacteria (SRB) induced corrosion bring harm to the safe operation of pipeline. In this article, the SRB induced corrosion of pipeline steel L360 in fluid scouring environment was studied comparatively by means of numerical simulation and simulation experiments. The predicted cloud map and particle motion trajectory map of the distribution for corrosion areas of pipeline steel were obtained by using computational fluid dynamics (CFD) simulation. Results showed that the most serious corrosion located at the bottom of the pipeline, the corrosion degree at the outlet of the pipeline was higher than that at the entrance of the pipeline. Electrochemical methods and surface analysis methods were used to characterize the SRB induced corrosion in solid-liquid two-phase flowing environment. Results show that when the biofilm of SRB did not exist on the metal surface (i.e., no biofilm of SRB has been formed on the steel through a pre-treatment), the scouring corrosion is dominant, the metal surface shows obvious scouring corrosion characteristics, and the corrosion products are mainly iron oxides. When SRB has formed a dense biofilm on the metal surface (after a proper pre-treatment), SRB corrosion dominates, and the biofilm will inhibit the scouring corrosion, but the life activity of SRB under the film will induce the electron exchange with the metal matrix, so that SRB induced corrosion occurs, and the corrosion products consist mainly of sulfur and iron compounds.

Key words： erosion corrosion sulfate reducing bacteria CFD simulation electrochemical analysis
