Abstract

The morphology, structure, and migration of granular pollutants in groundwater are significant in protecting water resources and geological disasters. However, it is difficult to monitor granular pollutants' migration and their parasitic environment under a complex groundwater environment. In this paper, a portable ultrasound diagnostic instrument (PUDI) is used to perform the experimental analysis and visual diagnosis of granular pollutants in groundwater environment and their water-soil-rock interfaces. A visual monitoring method is proposed for the real-time monitoring of the granular pollutants between the water-soil-rock interfaces. Results show that the real-time imaging diagnosis, monitoring, and visual analysis of granular pollutants in the groundwater and water-soil-rock interface can be realized by obtaining the ultrasonic images using the PUDI. The regional imaging size, migration path, and potential harm degree of granular pollutants can be obtained through continuous ultrasound imaging experiments and feedback parameters. The imaging accuracy of underwater particulate pollutants is 0.1 mm. The real-time monitor of granular pollutants and their migration can be realized in groundwater, even though the moving speed of granular pollutants is up to 0.1 m/s, and provides a new technical means for the prevention of granular pollution sources and some potential geological hazards.

便携式超声诊断仪在水-土-岩界面颗粒污染物监测中的应用

地下水中颗粒污染物的形态、结构和迁移对保护水资源和地质灾害具有重要意义。然而，在复杂的地下水环境下，颗粒污染物的迁移及其寄生环境很难监测。本文利用便携式超声诊断仪（PUDI）对地下水环境中的颗粒污染物及其水-土-岩界面进行了实验分析和可视化诊断。提出了一种实时监测水-土-岩界面颗粒污染物的可视化监测方法。结果表明，利用PUDI获取超声图像，可以实现地下水与水-土-岩界面颗粒污染物的实时成像诊断、监测和可视化分析。通过连续的超声成像实验和反馈参数，可以获得颗粒污染物的区域成像大小、迁移路径和潜在危害程度。水下颗粒污染物的成像精度为0.1毫米。即使颗粒污染物的移动速度高达0.1米/秒，也可以在地下水中实现对颗粒污染物及其迁移的实时监测，为预防颗粒污染源和一些潜在地质灾害提供了新的技术手段。

期刊介绍： IEEE Instrumentation & Measurement Magazine is a bimonthly publication. It publishes in February, April, June, August, October, and December of each year. The magazine covers a wide variety of topics in instrumentation, measurement, and systems that measure or instrument equipment or other systems. The magazine has the goal of providing readable introductions and overviews of technology in instrumentation and measurement to a wide engineering audience. It does this through articles, tutorials, columns, and departments. Its goal is to cross disciplines to encourage further research and development in instrumentation and measurement.
