金堤河流域台前段地下水水化学特征

Groundwater Hydrochemical Characteristics of Jindi River in Taiqian County

为了查明金堤河流域台前段地下水水化学特征,采集具有代表性的地下水水样对研究区地下水进行了研究。结果表明:台前县地下水水化学类型主要为HCO3·Cl—Na·Ca·Mg型水,咸水、微咸水、高铁、高锰、高氟水等原生劣质水均有分布;研究区南部,黄河影响带水质较好,黄河与金堤河交接洼地和滞洪区水质较差,位于黄河侧渗影响范围的地区水质较好,深层水则基本没有受到污染影响;受台前县三废排放影响,县城附近NO3-含量较高,已经对地下水造成了污染;台前县基本未受到有机污染或有机污染很轻。

In order to identify the chemical characteristics of groundwater in Jindi River basin in Taiqian County,it studied the groundwater of the studied area by collecting typical groundwater samples.The results show that the Taiqian County groundwater chemical types are mainly HCO3·Cl—Na·Ca·Mg type water,the salt water,brackish water,high iron,high manganese,high fluoride water and other primary poor quality water are determined among the area.In the south of the study area,influenced by the Yellow River,it＇s with better water quality.The water quality in the depression and detention basin between the Yellow River and Jindi River are poor.The area influenced by lateral seepage of the Yellow River is with better water quality.And deep water is basically not affected by the pollution.Affected by three wastes emission of Taiqian County,near the County the NO-3 with high content,have polluted the groundwater.The Taiqian County basic not subject to organic pollution or organic pollution is very light.
