Problems solved by technology

Moreover, most of the existing devices are made of plexiglass and PVC. Because their components contain pollutants such as phthalic acid lipids, it is impossible to carry out research on some organic substances. This type of material may contain toxic additives and plasticizers, which will easily cause environmental pollution after aging. Pollution and harm to the health of experimenters

Abstract

The invention discloses a three-dimensional visible simulation device for simulating migration and transformation of pollutants in porous media in an underground environment. The three-dimensional visible simulation device comprises a water supply device, a simulation device and a water storage device which are sequentially connected. The simulation device is a square tank with an upper cover. Two stainless steel screen devices in the tank divide the interior space of the tank into a water inlet pool, a water bearing layer and a water outlet pool. The water supply device is connected with the water inlet pool. The water storage device is connected with the water outlet pool. Sampling devices are arranged on the side wall, in the region of the water bearing layer, of the tank and the upper cover respectively. The three-dimensional visible simulation device has the advantages that through design of different types of filling media, underground heterogeneous water bearing layers are simulated, conditions, such as running water field, of underground water bearing layers are set, and a scientific and reasonable sampling method is designed; the concentration of pollutants, tracer agents and the like at different water levels are monitored continuously, and distribution and transformation of the target pollutants at different time in different space are analyzed; the three-dimensional visible simulation device is suitable for three-dimensional research on migration and transformation of the pollutants in the underground saturated heterogeneous water-bearing layer environment.

Description

technical field [0001] The invention relates to the field of soil and groundwater pollution restoration, in particular to a three-dimensional visual simulation device for simulating migration and transformation of pollutants in porous media in an underground environment. Background technique [0002] As important natural resources, soil and groundwater have played an important role in maintaining the healthy development of my country's economy and society and the ecological environment. However, with the rapid development of economy and society, the pollution of soil and groundwater is becoming more and more serious. The pollution remediation of soil and groundwater is inseparable from the study of the migration behavior and transformation of pollutants in the underground environment. In theory, the temporal and spatial distribution of pollutant concentrations and hydrogeological conditions can be obtained by establishing a large-scale field test site, combined with numerica...
