黄河下游平原地下水有机污染特征分析

以大量的地下水测试数据为基础,从污染源分布及水文地质条件入手,对黄河下游平原地下水中有机污染物类型及污染程度进行了深入研究。黄河下游平原地下水普遍受到有机物污染并形成多个典型有机污染区,有机物总检出率为35.5%,检出的有机污染物种类达29种,单个样品检出的有机物种类最多达19种,部分有机物含量超过地下水饮用标准,致使地下水质量恶化。地下水污染区的分布及污染程度与污染源的种类和分布具有很好的相关性。

Studies on Characteristics of Organic Pollution of Groungwater in the Yellow River Downriver Plain

Based on abundant data from sampling and testing, from the aspect of pollution source distribution and hydrogeological condition, in this paper, the content and degree of organic pollutants of the groungwater overland in the lower reach plain of the Yellow river have been studied. It is showed that the groungwater has been well received by organic pollutants and formed many groungwater contaminated areas. The percentage of organic pollutants detected are 35.5%, detected polluted materials are 29 species, and monosamples are 9 species. The contents or some organic materials are over the standard of drinking water. It has caused the quality of groungwater begin deteriorate. Distribution of polluted areas has a close relation with the degree and types of the contaminated sources.
