摘要
以松花江哈尔滨段污染为例,通过室内模拟槽研究了江水倒灌过程中主要氧化还原敏感性物质的水文地球化学迁移转化过程。研究结果表明,氧化还原灵敏性物质(如SO42-、Fe3+、NO3-、COD、HCO3-)在不同水文地球化学条件下形成各自的氧化还原优势带,各氧化还原污染物之间存在显著相关性,其迁移转化过程主要是消耗有机物的氧化还原反应和消耗氧的氧化还原反应。
The hydrogeochemical transportation and transformation of redox-sensitive compounds seeped from the water of the Songhua River in Harbin City was studied through a flume experiment. The results show that sensitive compounds, such as SO4^2-, Fe^3＋, NO3^-, COD, and HCO3^-, have their own redox dominant zones, and have a correlation with each other. The transportation and transformation of the sensitive pollutants are redox reactions consuming organics and oxygen.
