摘要

摘要: 渗滤液成分复杂，在收集和输运过程中极易引起管道结垢腐蚀，对环境形成潜在风险。选取4种典型管材，包括钢管、镀锌管、HDPE管和PVC管作为实验管材，制备样片后分别浸置于有氧和厌氧条件控制下的渗滤液中，研究其耐腐蚀性能。通过样片称重分析，结合材料性能表征，发现材料结垢量、腐蚀程度与其表面粗糙度显著相关；通过样片的结垢性腐蚀程度分析，4种材料的优劣顺序为HDPE > PVC > 镀锌管 > 钢管。研究结果对渗滤液收集输运系统管材选择及保障填埋场安全运营具有一定指导意义。

Abstract: Leachate, because of its complex and harmful components, which may accelerate pipes scaling and corrosion during its collection and transportation, poses potential risk to the environment. In this study, four typical pipe materials, including steel pipe, galvanized pipe, HDPE pipe and PVC pipe, were processed into experimental samples and immersed into leachate under aerobic and anaerobic conditions, investigate their corrosion resistance. Through the analysis of the samples weight changes, combined with the characterization of material properties, it was found that the scale formations and degree of corrosion were significantly related to the samples surface roughness. The rank of the materials was as HDPE > PVC > RC > TC. This study was expected to provide useful insights into the selection of pipe materials for leachate collection and transportation, ultimately to ensure the safe operation of the landfill.
