Description

Technical Field

[0001] This utility model relates to the field of permeable reactive wall technology, specifically a permeable reactive wall structure for groundwater remediation. Background Technology

[0002] With the rapid development of modern science and technology and industry, various industries are thriving. However, the corresponding cost is increasingly serious environmental pollution, especially in recent years, due to the rapid expansion of urbanization, which has led to a significant increase in sewage discharge and a growing trend of water pollution. Groundwater is an important freshwater resource and drinking water source, and its pollution has a huge impact. In response to the national groundwater pollution prevention and control project, various methods for purifying groundwater have emerged, among which permeable reactive barriers have shown particularly outstanding prevention and control effects.

[0003] Existing permeable reactive walls lack an anti-corrosion coating, making them susceptible to corrosion by wastewater, thus reducing their service life. Furthermore, the height of the permeable reactive wall is difficult to adjust, requiring manual removal of the internal reactive materials from the groundwater for replacement – ​​a time-consuming and labor-intensive process. Additionally, the adsorption filter layer, anaerobic filter layer, and bioreactor layer are difficult to disassemble, leading to clogging over time, making them impossible to disassemble for cleaning or replacement when damaged, significantly reducing the repair effect. Therefore, this invention provides a permeable reactive wall structure for groundwater remediation. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a permeable reactive wall structure for groundwater remediation, which has the following beneficial effects:

[0016] This groundwater remediation permeable reactive barrier structure, through the coordinated arrangement of a motor, transmission rod, threaded rod, limiting slider, and the permeable reactive barrier itself, allows for easy adjustment of its height. The presence of an anti-corrosion coating protects the surface and interior of the reactive barrier from corrosion caused by prolonged immersion in groundwater. The structure also incorporates a first slot, second slot, third slot, first connecting block, adsorption filter layer, first handle, second connecting block, anaerobic filter layer, second handle, third connecting block, biological reaction layer, and third handle for operation. Hold the first, second, and third handles and lift them upwards, then pull the first, second, and third connecting blocks out of the first, second, and third slots respectively. This allows the adsorption filter layer, anaerobic filter layer, and bioreactor layer to detach from the permeable reaction wall, facilitating the disassembly of these layers. Through the coordinated arrangement of these layers, the adsorption filter layer traps and filters large particles and suspended solids in the groundwater. The anaerobic filter layer hydrolyzes large insoluble molecules in the groundwater into small soluble molecules. Finally, the bioreactor layer adsorbs organic pollutants in the groundwater, reducing their concentration and thus remediating the groundwater. Attached Figure Description
