采用失重法和电化学阻抗谱（EIS）方法，系统研究了再生水中生物膜对铸铁管腐蚀的影响。结果表明，与无菌水相比，再生水中生物膜的存在明显促进了腐蚀过程。采用表面形貌仪、扫描电镜（SEM）和能谱仪（EDS）研究了铸铁试样上生物膜的特征。生物膜中的细菌计数使用标准平板计数方法和最可能数（MPN）来确定。结果表明，生物膜中的微生物、EPS和腐蚀产物等因素综合影响着腐蚀过程。但是，腐蚀机理随时间的不同而不同，在我们的研究中可以分为三个阶段。此外，提出了几种相应的腐蚀机制，为不同的浸泡时间。
Biofilm influenced corrosion on cast iron pipes in reclaimed water was systemically studied using the weight loss method and electrochemical impedance spectroscopy (EIS). The results demonstrated that compared to sterile water, the existence of the biofilm in reclaimed water promoted the corrosion process significantly. The characteristics of biofilm on cast iron coupons were examined by the surface profiler, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The bacterial counts in the biofilm were determined using the standard plate count method and the most probable number (MPN). The results demonstrated that the corrosion process was influenced by the settled bacteria, EPS, and corrosion products in the biofilm comprehensively. But, the corrosion mechanisms were different with respect to time and could be divided into three stages in our study. Furthermore, several corresponding corrosion mechanisms were proposed for different immersion times.
