MRS方法在地下水有机污染检测中的应用初探

Application of Magnetic Resonance Sounding(MRS) Method in Detecting Underground Water Pollution by Organic Compounds

我国地下水资源已面临污染的威胁,准确检测地下水水质的污染情况,特别是选择检测地下水有机污染的方法具有重要意义。与传统的地下水污染检测的地球物理探测方法相比,近年来发展起来的磁共振测深(MRS)方法具有许多优点。本文论述了利用磁共振技术的MRS方法应用在地下水有机污染检测方面的物质基础和方法特点、在圈定污染流体可能的运移通道、动态监测污染物的变化和防污装置泄漏的检查观测方面的功能和地球物理响应;提出了关于提高检测有机污染物的灵敏度和对污染异常的鉴别能力的技术措施的建议。

The pollution of underground water resources is threatened seriously in China, so it is important to detect the underground water quality. The method of detecting its pollution by organic compounds is of great significance. As compared with traditional geophysi cal methods of detecting pollution of underground water, the method of magnetic resonance sounding（MRS）that has been developed for the recent years has a lot of advantages. In this paper, it discusses the material basis and the features of detecting pollution of underground water by organic compounds when applying MRS of Nuclear Magnetic Resonance （NMR） technology. And it considers functions and geophysical responses of enclosing the possible transportation channels of polluting fluid and dynamically monitoring variations of polluting fluid and detecting leakage of antipollution instrument. Finally, it proposes the measure of increasing sensibility of detecting organic compounds and the ability of discriminating pollution.
