Description

technical field [0001] The invention belongs to the field of environmental simulation technology research, and more specifically relates to an integrated simulation device for simulating groundwater pollution process and pollution restoration. [0002] The invention also relates to a method of use of the above device. Background technique [0003] As an important water source for urban and rural water supply, groundwater plays an irreplaceable role in maintaining the healthy development of the economy and society. However, due to the impact of human activities, a large number of pollutants enter the groundwater environment, causing the problem of groundwater pollution to become increasingly serious. Therefore, for many years, many scientific researchers have been engaged in the scientific research of groundwater pollution prevention and control. An important means to study such scientific issues is to build an experimental device to simulate the groundwater environment, and...

Problems solved by technology

[0004] The study found that there are some shortcomings in today's groundwater physical simulation devices: First, the small simulation devices used in the laboratory, such as soil columns or small simulation tanks, are simple to operate, easy to replace media materials and low in cost, but the groundwater environment The complexity of these devices makes it difficult to simulate the real groundwater environment

However, after the pollution remediation process, especially the PRB remediation technology, for example, the common method of PRB setting is to excavate the medium at the setting position and then fill the remediation material. After the remediation test is completed, the water content in the remediation material gap is refilled. The permeability of the layer medium material is different from the original one, which is not conducive to re-doing other related simulation experiments, and the thickness of the PRB wall cannot be set according to the different repair materials.
