摘　　要：通过对接纳石油化工废水的水体周围地下潜水的监测,发现纳污水体周围地下水污染因素与地表纳污水体中较高含量污染物一致,即都主要为有机污染,纳污水体中污染物浓度高,则潜水中该污染物浓度相应较高。说明纳污水体所接纳的含高浓度的石油类、化学耗氧量和五日生化需氧量的有机污染废水对周围地下水产生了比较明显的污染作用。污染范围是以泡子为中心,向四周呈椭圆形扩散形成污染晕,随着距离纳污水体距离的增加,污染物浓度呈下降趋势,在泡子溢流口和进水口处污染晕向外延伸。By monitoring the underground water around petrochemical wastewater - holding water body. It is found that pollution factor in under ground water around pollutant - holding water body is consistent with high content pollutant in surface pollutant - holding water body, that is to say, mainly because of organic pollution, the higher the concentration of pollutant in pollutant - holding water body, the higher the concentration of the same pollutant in underground water. It shows that the organic sewage of high concentration of oil, CODCr and BOD5 has obviously polluted the ground water. The range of pollution is lake at the core, it spreads all around in ellipse form, and takes shape pollution halo, with the increase of distance from pollutant -holding water body, the concentration of pollutant decreases, the pollution halo stretches outward around overflow outlet and inlet.
