Description

Technical Field

[0001] This invention relates to the field of groundwater remediation technology, and in particular to an environmentally friendly groundwater remediation structure and equipment. Background Technology

[0002] Groundwater remediation refers to the use of technologies such as extraction, airlift, bioremediation, and permeable reactive barriers to restore contaminated groundwater to its original quality. Groundwater resources are an important component of water resources, and groundwater pollution occurs frequently in my country. The implementation of groundwater pollution control and remediation is of great significance for the sustainable use of groundwater resources.

[0003] Reactive infiltration wall technology, also known as activated permeable wall, is a rapidly developing in-situ remediation technology for groundwater pollution. It involves installing a highly permeable activated material wall downstream of the contaminated area, trapping and treating pollutants in the plume, thus purifying the groundwater.

[0004] Existing impermeable funnel-type permeable reactive walls used for groundwater pollution remediation are typically monolithic, non-removable structures. After installation, maintenance or testing requires complete dismantling. However, after a period of use, not all areas accumulate significant amounts of harmful pollutants in the groundwater. Complete dismantling greatly increases construction costs and complexity, is time-consuming and labor-intensive, and wastes resources. Furthermore, the existing walls often feature layered purification layers laid flat, and the permeation process typically extends beyond the wall's thickness, resulting in ineffective purification and remediation. Summary of the Invention

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0050] Example 1

[0051] like Figures 1-9 As shown, an environmentally friendly groundwater remediation structure includes a main cylinder 1, which is configured as a cylinder structure with an open bottom; specifically, the main cylinder 1 is configured as a cylinder structure with a sealed front and an open rear.

[0052] The inner cavity of the main cylinder 1 is divided into a first cavity 101, a second cavity 102 and a third cavity 103 from the inside to the outside by a first annular partition 11 and a second annular partition 12. Specifically, the first cavity 101 is configured as a cylindrical cavity, and the second cavity 102 and the third cavity 103 are configured as annular cavities.

[0053] The bottom of the first annular partition 11 is provided with a first hole group 104 for connecting the first cavity 101 and the second cavity 102; the upper part of the second annular partition 12 is provided with a second hole group 105 for connecting the second cavity 102 and the third cavity 103; the front wall of the first cavity 101 is perforated with a third hole group 106 for connecting the first cavity 101 and the outside of the main cylinder 1; in this scheme, the groundwater flows from the third hole group 106 into the first cavity 101, then through the first hole group 104 into the second cavity 102, and then through the second hole group 105 into the third cavity 103. The first cavity 101 is provided with a spiral blade 13, which divides the first cavity 101 into a spiral channel 107. By setting the spiral channel 107, the groundwater is dispersed in a spiral manner, so that the substances to be purified in the groundwater are in a discrete state. The second cavity 102 is used to reduce the flow rate of the groundwater, and the third cavity 103 is used to repair the groundwater in a low-speed state.

[0054] In order to control the flow direction of groundwater, a cover 14 is provided at the tail of the main cylinder 1. The cover 14 is used to close the first cavity 101 and the second cavity 102.

[0055] Repair cylinder 2 is detachably fitted and inserted into the third cavity 103; specifically, the middle part of the repair cylinder 2 is provided with an installation cavity 20 for fitting onto the outer wall of the second annular partition 12; the repair cylinder 2 is also provided with a receiving groove 21, and the repair core 3 is installed in the receiving groove 21; the receiving groove 21 is set as an annular cavity.

[0056] To ensure that groundwater can flow smoothly into the receiving cavity 21, the front end of the repair cylinder 2 is also provided with a fifth hole group 108 for connecting the receiving cavity 21 and the outside of the repair cylinder 2; at the same time, the front end of the repair cylinder 2 is provided with a mounting plate 24 through the support column 23 to ensure that groundwater can enter from the fifth hole group 108.

[0057] The repair core 3 is embedded within the repair cylinder 2. The repair core 3 is composed of multiple layers of activated carbon 31, pebble layers 32, and reactive material layers 33 stacked alternately. In this design, the reactive material layer 33 may contain zero-valent iron, organic waste, clay minerals, and phosphates, facilitating the infiltration reaction of groundwater. The activated carbon layer 31 utilizes its excellent physical and chemical adsorption properties to adsorb pollutants in the groundwater, further purifying the water quality. The pebble layer 32 can block the flow of larger particulate impurities in the groundwater. Preferably, in this design, the above functional layers are arranged in a ring-shaped structure using a mesh or mesh plate, with multiple functional sheets stacked to form the repair core. The number of functional sheets can be increased or decreased according to the specific conditions of the groundwater.

[0058] The tail cap 4 is detachably installed at the tail of the main cylinder 1. A fourth hole group 43 is perforated on the tail cap 4 to connect the third cavity 103 with the outside of the main cylinder 1. In this design, the repaired groundwater flows out through the fourth hole group 43. A rotating handle 45 is also provided on the back of the tail cap 4; an annular washer 42 is also provided on the front of the tail cap 4.

[0059] To enable the detachable installation of the tail cap 4, the outer wall of the main cylinder 1 is provided with limiting protrusions 15, and at least two limiting protrusions 15 are provided. Specifically, in this design, four are provided and symmetrically arranged. The tail of each limiting protrusion 15 extends beyond the tail of the outer wall of the main cylinder 1 and has an arc-shaped groove 1501 on its inner side. The edge of the tail cap 4 is provided with an arc-shaped protrusion 44, which can be fitted into the arc-shaped groove 1501. Specifically, to ensure accurate fitting of the arc-shaped protrusion 44, the arc-shaped groove 1501 is designed as a non-through groove structure, and a stop is provided at the end of the arc-shaped groove 1501.

[0060] To facilitate matching and combining the dimensions of the repair structure, the first hole group 104, the second hole group 105, the third hole group 106, and the fourth hole group 43 are hole groups of equal diameter. On the other hand, the hole diameters of the first hole group 104, the second hole group 105, the third hole group 106, and the fourth hole group 43 can also be set to different sizes according to the specific groundwater conditions.

[0061] To prevent impurities in the groundwater from entering the main cylinder 1 and causing blockage inside the main cylinder 1, a conical outer shell 6 is provided at the front end of the main cylinder 1, and a filter hole group 61 is hollowed out on the conical outer shell 6.

[0062] How to use this repair structure:

[0063] The repair structure is installed on the groundwater repair wall, with the end containing the conical outer shell 6 pointing towards the source of the groundwater. The groundwater is first filtered by the filter hole assembly 61 to remove larger impurities, and then enters the spiral channel 107 for dispersion, causing the impurities to become disordered. The disordered groundwater is then guided by the second cavity 102 to reduce its flow velocity; the slow-moving, disordered groundwater is then repaired by the repair core 3 before being discharged from the main cylinder 1, completing the groundwater repair work.

[0064] When the repair effect of the repair core 3 decreases and it needs to be replaced, rotate the tail cap 4 to remove the repair cylinder 2, and then replace the repair core 3.

[0065] Example 2

[0066] like Figures 10-12 As shown, an environmentally friendly groundwater remediation device includes the aforementioned remediation structure. Specifically, the remediation device is configured as a wall 5, on which a plurality of mounting holes 51 are arrayed.

[0067] The mounting hole 51 includes a main mounting hole 5101 for mounting the main cylinder 1 and a limiting mounting hole 5102 for mounting the limiting protrusion 15.

[0068] The wall 5 is also provided with a cross-shaped limiting member 52; the cross-shaped limiting member 52 is rotatably set on the back of the wall 5 by means of a pin, and is used to limit the main cylinder 1 after installation.

[0069] By adapting and optimizing the wall structure and combining it with the repair structure, the repair mechanism can be quickly removed for replacement or maintenance. Installation and disassembly are convenient and quick, without the need for complete demolition. This targeted approach reduces construction costs and task difficulty, and avoids resource waste.

[0070] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
