Hydrogeochemical Indices of Groundwater Pollution Induced by Oil Sewage Leakage一一A Study Case of the Groundwater Source in Zibo City, Shandong Province, China

摘要: 油类污染地下水的过程中发生了各种物理作用、化学作用和生物作用。本文利用山东省淄博市某地下水饮用水源地油类污染事故的资料,通过地下水环境对照值的统计,首次研究了地下水油类污染与其他组分的关系,以及油类污染地下水造成的地下水地球化学的变化。提出地下水环境对照值可以作为地下水是否受到油类污染的水文地球化学指标。研究区中地下水油类重污染区的Cl-COD、硬度和矿化度升高幅度较大,而轻微污染区则升高幅度较小;对于3则在油类重污染区含量非常低,而轻微污染区则升高。研究区地下水地球化学环境的变化是由于油类污染过程中离子交换作用和硝化作用与反硝化作用等水文地球化学作用的结果。Abstract: Physical, chemical and biologiocal reactions occur in the process of the oil pollution in groundwater.By using the oil pollution moitoring data of a drinking groundwater source in Zibo City,East of China,the hydrogeochemical change and the relation between total oil concentration and the other componentsin ground waterwere studied for the first time. Someground water environmental background values weresuggested to be the important hydrogeochemical indices of the oil pollution in groundwater. The moreserious the pollution of groundwate, the greater magrritude the increase Cl-,CO D, hardness and TDS.Oppositely,the lower the oil content of groundwater, the higher the level of NO3The hydrogeochenical change is resulted by hydrogeochmical reactions such as ionic exchtinge, nitration and countergi-nitrati on.
