鲁北平原浅层地下水有机污染特征及污染来源分析

本文在对鲁北平原水文地质条件及污染源现状分析的基础上,对浅层地下水进行了高密度的样品采集、高精度的污染物组分测试及污染程度研究,分析研究结果表明:鲁北平原浅层地下水在部分地区受到有机物污染,污染程度总体较低,个别地区出现中度污染和重度污染。检出的有机污染物共13种,个别有机物含量高。浅层地下水污染区的分布及污染程度,与油田采油区位置及石油化工企业的分布具有相关性。

Analysis of Characteristics and Origin of Organic Pollution in Shallow Groundwater of the Lubei (Northern Shandong) Plain

Based on the data from dense sampling and accurate testing, associated with the hydrogeological condition and pollution situation of Lubei plain, the authors studied the content and the extent of organic pollution in the shallow groundwater. The results show that the shallow groundwater has been subjected to extensive organic pollution and formed many shallow contaminated areas. It is shown that organic pollutants have 13 species, with one or two species having very high content. The area coverage and extent of the contamination are controlled by the plant location of the Shengli oil field and the distribution of petrochemical enterprises.
