摘　　要：微生物腐蚀是全球下水道混凝土结构的巨大挑战之一。本文详细综述了混凝土微生物腐蚀(MICC)的三个阶段(非生物中和作用、微生物定植和混凝土腐蚀破坏),分析了污水组成、环境因素、耦合腐蚀作用、生物因素和管道因素等影响因素对MICC速率的影响,并强调了各因素之间的相互作用;论述了矿物硫酸试验、生物硫酸试验、强化污水腐蚀试验、实验室模拟试验、全尺寸试验和原位暴露试验等多种MICC模拟试验方法,并对比各种试验方法的主要优缺点。最后归纳了目前MICC研究中存在的关键问题,如生物膜作用和微生物的协同作用、试验标准和评价标准、钢筋的加速腐蚀作用等,指出未来研究方向,为地下污水管道MICC研究提供思路。Microbiologically influenced corrosion poses a significant challenge to concrete sewer structures globally.This article provides a detailed explanation of the three stages of microbiologically influenced corrosion of concrete(MICC),i.e.,non-biological neutralization,microbial colonization,and concrete corrosion and deterioration.Factors influencing the corrosion rate of MICC,such as sewage composition,environmental factors,coupled corrosion effect,biological factors,and pipeline factors,are reviewed,emphasizing the interplay among these factors.Various MICC testing methods,including mineral sulfuric acid test,biological sulfuric acid test,enhanced wastewater corrosion test,laboratory simulation test,full-scale test,and in-situ exposure test,are discussed.The major advantages and disadvantages of these assessment methods are outlined.Finally,the key issues in current MICC research are summarized,such as the synergistic effect of biofilm and microorganisms,experimental and evaluation standards,and the acceleration effect of steel reinforcement.Future research directions are pointed out,providing ideas for the study of microbial corrosion of concrete in underground sewage pipelines.
