【摘要】 本文通过对大庆西部地区铁的地球化学、水文地球化学环境特征的调查,探讨了铁的富集、变化与地球化学、水文地球化学环境的关系和生物化学环境特征。用热力学方法计算了地下水中铁的迁移形式,讨论了铁的电化学作用并给出了地下管道和地下井管被腐蚀的原理及防治的措施。更多还原

【Abstract】 Through the investigation on the geochemistry, hydrogeochemistry—environment of iron in western Daqing region, We discuss the relation between the environment, change of iron and features of the geochemistry, hydrogeochemistry, as well as the environmental characteristics of the biochemistry. The migrating form of iron in the underground water, and the electrochemical function of iron are determided by using thermodynamics. The corrosion principle as well as preventive measurments and treatments for the underground conduits and subsurface well cassing are proposed.更多还原
