| 摘 要： | 滦河三角洲是中国北方重要经济区,人口众多,地下水是主要供水水源。在工业和生活污染物排放及农业施用化肥的影响下,地下水遭受一定程度的污染。笔者近年来在滦河三角洲地区开展了野外调查,采集了399组地下水样品,每个样品检测污染指标34项。其中包括,三氮、毒性重金属指标、挥发性有机指标、半挥发性有机指标。本文采用综合污染指数法对滦河三角洲地下水污染状况进行了评价。结果表明:滦河三角洲以工业污染为主,其次为农业污染。浅层地下水以轻微污染为主,未污染比例较低,极重污染的比例相对较高,主要受人类活动影响。深层地下水也有一定程度的污染,但比浅层地下水轻,仅少量的水样点显示轻污染、极重污染,这些样点主要呈点状零星分布。地下水污染的主要因素为“三氮”,浅层地下水多受到轻微污染。

| Abstract: | The Luanhe river delta with large population is one of the key economic zones of North China. Ground-water is main water supply source in the area. The groundwater has been polluted due to the sewage from indus-try and town living, also fertilizer and pesticide from agriculture. Field investigation was conducted in the delta where 399 groundwater samples were collected. Each sample has been test 34 indexes that include three nitrogen indicators, toxic heavy metal indicators, VOCs and SVOCs. The groundwater pollution situation has been evaluat-ed by the Comprehensive Contamination Index Method. It turns out that the groundwater pollution is mainly in-fluenced by industrial pollution, followed by agricultural pollution in the delta. The shallow groundwater has been contaminated by human activities, mainly slightly contamination. The ration of uncontaminated groundwa-ter is lower than the very heavily contaminated. The deep groundwater quality is better than the shallow. A few of samples show lightly or very heavily polluted. The polluted water distributes point-like type. The main factors in-fluence groundwater quality that has been slightly polluted due to“three nitrogen”. |
