Description

Technical Field

[0001] The present invention relates to the technical field of groundwater pollution control, and in particular to a repair device for groundwater pollution control. Background Art

[0002] As agricultural planting areas develop towards intensive, specialized, farm-based and large-scale models, chemical fertilizers and organic fertilizers are used in large quantities in the production process, and nitrogen-containing wastewater discharged during industrial production has long infiltrated into groundwater. This series of factors has led to a significant increase in the nitrate content in groundwater, especially in areas where shallow groundwater is used as a water source, where groundwater is extremely susceptible to pollution. Once groundwater is polluted, the difficulty of repair and treatment will increase significantly, posing severe challenges to the safety and sustainable use of water resources.

[0003] Related technology can refer to the Chinese patent with authorization announcement number CN114653133A, which discloses a groundwater pollution control and restoration device, including a filter ring, a rotating ring body is provided on the outer sleeve of the filter ring, and a plurality of water tanks are evenly distributed on the circumference of the inner wall of the rotating ring body, a movable pipe is provided in the filter ring, and a drainage structure is provided on one side of the movable pipe, and an opening structure for facilitating the discharge of sewage into the filter ring is provided on the upper surface of the outer wall of the movable pipe, and an opening for facilitating the discharge of sewage into the drainage structure is provided on the lower surface of the outer wall of the movable pipe. A sedimentation tank is provided above the movable pipe, which can filter the underground sewage in batches, making the filtration more accurate and the filtering effect better, and can also perform cyclic filtration on the sewage after batching, thereby increasing the number of filtration times and improving the quality of sewage treatment. After each batch of sewage is filtered, water is automatically introduced and drained, thereby improving the filtration efficiency. At the same time, the above structures realize synchronous work, and a linkage structure is adopted to realize the work of multiple steps.

[0004] However, the above scheme still has the following defects. Groundwater flow is affected by many factors, including soil porosity, rock layer structure, and changes in groundwater levels. These factors make the distribution of groundwater uneven at different depths and directions. When the water inlet pipe connected to the output end of the pump is inserted into the ground, it is difficult to effectively guide and converge water flows from different directions. In addition, the design of most water inlet pipes only allows a single direction of water flow path, limiting its ability to capture and guide groundwater from multiple directions. This design allows groundwater to flow only in the direction of the opening of the pipe, and it is impossible to achieve all-round convergence and guidance. Summary of the invention

[0005] The present application provides a repair device for groundwater pollution control, which has the function of effectively gathering and guiding groundwater from different directions, thereby improving water collection efficiency.

[0006] The present application provides a repair device for groundwater pollution control, which adopts the following technical solution: A repair device for groundwater pollution control, comprising a support base, a support column is fixedly installed on the upper surface of the support base, a repair treatment pool for repairing groundwater is provided on the support column, a first pumping pump is provided on the repair treatment pool, an output end of the first pumping pump is connected to a water outlet pipe, the water outlet end of the water outlet pipe extends to the inside of the repair treatment pool, an input end of the first pumping pump is connected to a water inlet pipe, the water inlet end of the water inlet pipe extends into the groundwater and is connected to a water extractor; The water dispenser includes a balancing plate, a sealing sleeve is provided at the bottom center of the balancing plate, a connecting sleeve is provided inside the sealing sleeve, the water inlet end of the water inlet pipe passes through the balancing plate and is connected with the connecting sleeve, the connecting sleeve passes through the bottom of the sealing sleeve and is connected with a water collection bag, the water collection bag is a hollow spherical structure, a plurality of water collecting pipes are provided at equal angles on the outside of the water collection bag, and a plurality of water collecting holes are provided on the water collecting pipes.

[0007] By adopting the above technical scheme, groundwater is effectively extracted into the repair and treatment pool by using the first water pump, and the water flow is first transported through the water extraction device and the water inlet pipe; in the repair and treatment pool, the extracted groundwater undergoes necessary chemical or biological remediation treatment to restore its water quality; the negative pressure generated by the first water pump prompts the groundwater to flow into the system; in this process, the negative pressure causes the water flow to be introduced into the water extraction bag through the water collection holes on the water collection pipe; the water extraction bag, as a hollow spherical structure, has a large volume and can store a certain amount of water under negative pressure conditions; the water flow is first guided into the water extraction bag through the holes on the water collection pipe, and then flows into the water inlet pipe through the connecting sleeve; the water collection pipes are evenly distributed around the water extraction bag, so as to effectively gather and guide groundwater from different directions through the water collection holes; this design not only improves the water collection efficiency, but also ensures the effective restoration of water quality.

[0008] Preferably, the cross-section of the balancing disk is a circular structure, and a plurality of supercharging turbines are arranged on the upper surface of the balancing disk at equal angles around the central axis thereof.

[0009] By adopting the above technical solution, the application of the booster turbine can generate up and down power in the groundwater, thereby realizing the rapid movement of the extractor to different groundwater layers; this power mechanism not only improves the movement efficiency of the extractor, but also helps to optimize the groundwater extraction process.

[0010] Preferably, a plurality of the water collecting pipes are arranged to be inclined downward and form a conical structure at the bottom of the water collecting bag.

[0011] By adopting the above technical solution, the gradually contracting design of the conical structure promotes the acceleration and smooth transition of the flow velocity during the fluid flow process; when the water flow enters the conical part, the flow velocity gradually increases, thereby effectively reducing the eddy currents and turbulence phenomena that may be generated during the flow process, while significantly reducing friction losses; this design optimizes the flow characteristics of the fluid and improves the overall efficiency of the system.

[0012] Preferably, downwardly inclined protective plates are provided on both sides of the water collecting pipe, and the protective plates form guide grooves of a V-shaped structure at the water collecting holes.

[0013] By adopting the above technical solution, the V-shaped guide groove design can effectively guide the water flow to the water collection hole; when the water flows into the guide groove, the shape of the guide groove concentrates and guides the water flow to prevent it from dispersing, thereby ensuring that more water can efficiently flow into the water collection hole; in addition, the downward inclined protective plate design uses the effect of gravity to cause the water entering the guide groove to flow downward quickly; this structure optimizes the directionality and flow efficiency of the water flow, and improves the overall performance of the water collection system.

[0014] Preferably, a filter is installed at the V-shaped opening of the guide groove of the protective plate.

[0015] By adopting the above technical solutions, the filter can effectively remove suspended impurities in the water and reduce the amount of pollutants entering the water collection system, thereby significantly improving the water quality of the final collected water; this is especially important in irrigation or water supply scenarios, as high-quality water sources are vital to both agriculture and human life.

[0016] Preferably, a driving motor is fixedly installed inside the sealing sleeve, and the output end of the driving motor is connected to a gear, one side of the gear is meshingly connected to a gear ring, the inner ring of the gear ring is fixedly connected to the outer ring of the connecting sleeve, and the connecting sleeve is connected to the water inlet pipe through a bearing.

[0017] By adopting the above technical solution, the gear drives the gear ring through the driving motor, and then drives the connecting sleeve to rotate inside the sealing sleeve; when the connecting sleeve rotates in the sealing sleeve, the centrifugal force causes the impurities on the connecting sleeve to be thrown to the outside; this process effectively cleans the surface of the filter and avoids the accumulation of impurities; with the action of centrifugal force, the impurities on the surface of the filter can be efficiently removed, thereby improving the cleanliness of the filter and ensuring unimpeded flow of water or gas.

[0018] Preferably, a built-in interlayer is provided inside the repair treatment pool, and the built-in interlayer is divided into a sedimentation tank and a repair pool inside the repair treatment pool. The groundwater extends to the sedimentation tank of the repair treatment pool through an outlet pipe, and the groundwater after sedimentation is pumped to the interior of the repair pool through a second water pump arranged on the repair treatment pool.

[0019] By adopting the above technical solution, groundwater flows into the sedimentation tank through the outlet pipe; in the sedimentation tank, the flow rate of groundwater is significantly slowed down, causing the solid particles and impurities suspended in the water to settle to the bottom under the action of gravity, thereby achieving preliminary purification; the clean water after sedimentation is transported to the remediation tank through the second pump installed on the remediation treatment tank; in the remediation tank, the water will be further treated to remove residual pollutants and impurities.

[0020] Preferably, an activated carbon adsorption element, a chemical repair layer and a biological repair layer are sequentially arranged inside the repair pool and along the water flow guide path.

[0021] The above technical solution is used to remove harmful impurities in groundwater.

[0022] Preferably, the activated carbon adsorbent comprises activated carbon particles and a containing box for containing the activated carbon particles, a water hole is provided inside the containing box, and a vibration plate and a driving member for vibrating the vibration plate are fixedly mounted on the top of the containing box.

[0023] By adopting the above technical scheme, activated carbon has excellent adsorption capacity due to its high specific surface area and rich pore structure, and can effectively remove harmful impurities, dissolved gases and organic pollutants in water; activated carbon particles use their unique physical and chemical properties to undergo adsorption reactions with harmful substances in water; by applying vibration through the driving component, the vibration plate in the containing box can enhance the movement of activated carbon particles in the water flow and promote their full contact with pollutants; this process increases the redistribution and fluidity of the particles through vibration, thereby significantly improving the adsorption efficiency of the activated carbon.

[0024] Preferably, a plurality of vibration plug plates are provided at the bottom of the vibration plate, and the vibration plug plates are inserted in the receiving box in a serpentine structure.

[0025] By adopting the above technical solution, when the driving component causes the vibration plate to vibrate, the vibration will be transmitted to the activated carbon particles in the containing box through the vibration plug plate at the bottom; the design of the serpentine plug plate effectively disperses the vibration, so that the vibration wave forms a more uniform vibration effect in the containing box; at the same time, the serpentine structure increases the turbulence of the water flow by changing the water flow path; the turbulent water flow can destroy the aggregation state between the activated carbon particles, enhance the freedom of movement of the particles, and thus increase the contact frequency between the particles.

[0026] In summary, this application has the following beneficial effects: 1. By using the first pump, groundwater is effectively extracted into the remediation pool, and the water flow is first transported through the water extractor and the water inlet pipe; in the remediation pool, the extracted groundwater undergoes necessary chemical or biological remediation treatment to restore its water quality; the negative pressure generated by the first pump causes the groundwater to flow into the system; in this process, the negative pressure causes the water flow to be introduced into the water collection bag through the water collection holes on the water collection pipe; as a hollow spherical structure, the water collection bag has a large volume and can store a certain amount of water under negative pressure conditions; the water flow is first guided into the water collection bag through the holes on the water collection pipe, and then flows into the water inlet pipe through the connecting sleeve; the water collection pipes are evenly distributed around the water collection bag, so as to effectively gather and guide groundwater from different directions through the water collection holes; this design not only improves the water collection efficiency, but also ensures the effective remediation of water quality.

[0027] 2. Through the driving component, the vibration plate is vibrated; this vibration will be transmitted to the activated carbon particles in the containing box through the vibration plug plate at the bottom; the design of the serpentine plug plate effectively disperses the vibration, so that the vibration wave forms a more uniform vibration effect in the containing box; at the same time, the serpentine structure increases the turbulence of the water flow by changing the water flow path; the turbulent water flow can destroy the aggregation state between the activated carbon particles, improve the freedom of movement of the particles, and thus increase the contact frequency between the particles.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0030] The present invention discloses a repair device for groundwater pollution control, such as Figure 1 As shown, it includes a support base 1, which is fixedly mounted on an external mobile body. The repair device with the support base 1 is moved to the position to be repaired by the external mobile body; the external mobile body allows the repair device to be moved between different positions to be repaired; this mobility is a major advantage in the treatment of groundwater pollution, because the pollution sources and affected areas are often widely distributed; the movable repair device makes it possible to effectively treat groundwater pollution under a variety of different geographical and environmental conditions; technicians can quickly respond to pollution incidents and adjust the treatment location according to actual conditions.

[0031] like Figure 1As shown, a support column 2 is fixedly installed on the upper surface of the support base 1, and a repair treatment pool 3 for repairing groundwater is provided on the support column 2, a fixed outrigger 4 is fixedly installed on the repair treatment pool 3, and a first water pump 5 is fixedly installed on the fixed outrigger 4, the output end of the first water pump 5 is connected to an outlet pipe 6, the outlet end of the outlet pipe 6 extends to the interior of the repair treatment pool 3, and the input end of the first water pump 5 is connected to an inlet pipe 7, the inlet end of the inlet pipe 7 extends into the groundwater and is connected to a water extraction device 8; by utilizing the first water pump 5, the groundwater is pumped to the interior of the repair treatment pool 3 through the water extraction device 8 and the inlet pipe 7, and the groundwater is repaired by the repair treatment pool 3; the pumped groundwater enters the repair treatment pool 3, where necessary chemical or biological repair treatment is carried out.

[0032] like Figure 2 Specifically, the water extractor 8 includes a balancing plate 801, the cross-section of which is a circular structure, and the upper surface of the balancing plate 801 is provided with four booster turbines 802 at equal angles around its own central axis. The booster turbines 802 are used to generate up and down power in the groundwater, thereby facilitating the rapid movement of the extractor to different groundwater layers.

[0033] like Figure 2 The circular design of the balance disk 801 can effectively disperse the power from all directions, improve stability and flexibility of underwater operations; the components arranged around the central axis ensure the balance and symmetry of the equipment, thereby reducing instability when moving in the water; the design of the booster turbine 802 is to generate up and down floating water flow power through rotation; this power not only helps the water extractor 8 to better position in the water, but also helps to improve the water extraction efficiency; the rotation of the booster turbine 802 causes the water flow to generate a pressure difference below and above the water extractor 8, thereby achieving up and down dynamic movement; this power enables the water extractor 8 to flexibly adjust its position and quickly move to different groundwater layers for water extraction operations; because it can move quickly between different water layers, the water extractor 8 is suitable for groundwater environments of various water levels and types, especially when the water extraction depth needs to be frequently adjusted.

[0034] like Figure 2 The internal speeds of the four boost turbines 802 are all controlled individually, and each turbine can adjust its speed as needed, thereby adjusting the generated water flow rate and pressure; the difference in the controlled speeds between different turbines helps to adjust the center of gravity and stability of the overall equipment, making the water extractor 8 more stable in complex waters and reducing jitter and instability during operation.

[0035] like Figure 2 and Figure 3A sealing sleeve 803 is fixedly installed at the bottom center of the balancing plate 801, and a connecting sleeve 804 is arranged inside the sealing sleeve 803. The water inlet end of the water inlet pipe 7 passes through the balancing plate 801 and is connected with the connecting sleeve 804. The connecting sleeve 804 passes through the bottom of the sealing sleeve 803 and is connected with a water collection bag 805. The water collection bag 805 is a hollow spherical structure. A plurality of water collecting pipes 806 are arranged at equal angles on the outside of the water collection bag 805. A plurality of water collecting holes 807 are arranged on the water collecting pipe 806. Under the action of negative pressure, groundwater passes through the water collecting holes 807 on the water collecting pipe 806, the water collection bag 805, the connecting sleeve 804 and the inside of the water inlet pipe 7 in sequence.

[0036] like Figure 2 and Figure 3 The negative pressure generated by the first water pump 5 in the system promotes the groundwater to flow into the system; using the negative pressure, the water flows through the water collection hole 807 on the water collection pipe 806 and is introduced into the water collection bag 805; the water collection bag 805, as a hollow spherical structure, has a large volume and can store a certain amount of water under the action of negative pressure; the water is first guided into the water collection bag 805 through the hole on the water collection pipe 806, and then flows into the water inlet pipe 7 through the connecting sleeve 804; the water collection pipe 806 is evenly distributed around the water collection bag 805, and the groundwater is sucked into the water collection bag 805 through the water collection hole 807. Through this design, groundwater from different directions can be effectively gathered and guided.

[0037] like Figure 2 and Figure 3 Therefore, through the design of the water collecting pipe 806 and the water collecting hole 807, groundwater can be guided in a larger range to increase the efficiency of water collection; the spherical feature of the water collecting bag 805 maximizes the available volume and can collect more water under the action of negative pressure; due to the design of the water collecting bag 805 and the setting of multiple water outlets, water can be absorbed at multiple locations at the same time, thereby improving the water source capture ability of the entire system.

[0038] like Figure 2 and Figure 3 , several water collecting pipes 806 are arranged to be tilted downward and form a conical structure at the bottom of the water collecting bag 805. The downward tilted water collecting pipes 806 use the effect of gravity to make the water flow downward in the pipe, reducing the resistance caused by the upward or horizontal flow of the water; this means that the water naturally flows downward along the tilted water collecting pipes 806 into the water collecting bag 805, which is more efficient; the conical structure helps to accelerate and smoothly transition the fluid during the change from wide to narrow; as the water flows into the conical part, the flow rate gradually increases, reducing the eddy and turbulence that may be generated by the flow, and effectively reducing friction losses; the conical bottom can cause the fluid to form a certain pressure difference during the flow process, promoting the smooth entry of water; this pressure difference can help the downward movement of the balancing plate 801, further improving the response speed and stability of the system.

[0039] like Figure 2 and Figure 3 Therefore, by reducing friction and flow resistance, the overall water flow efficiency is improved, thereby accelerating the speed at which water flows into the water collection bag 805; the conical bottom design helps to concentrate the water flow, so that more water can be collected faster, thereby improving the efficiency and amount of water collection.

[0040] like Figure 3 , the water collection hole 807 is set on the upper surface of the water collection pipe 806. When the water collection hole 807 is located on the upper surface of the water collection pipe 806, the natural flow of water will prompt water to enter the water collection pipe 806 from above; this arrangement utilizes the gravity and flow dynamics of the water flow, reduces the impact of the water flow on the silt therein, and thus reduces the probability of the silt being transmitted to the water collection hole 807; the water collection holes 807 are distributed on the upper surface, which can effectively reduce the backflow and seepage inside the pipeline; since the water flow mainly flows downward from the top, the deposited silt at the upper edge is easy to be brought into the orifice, while increasing the effective flow rate of the water flow, preventing the deposition of silt near the orifice; when water flows upward from a deeper depth, larger particle sediments will naturally sink due to gravity, thereby reducing the possibility of these particles being brought into the water collection hole 807.

[0041] like Figure 3 Therefore, the design of the water collection hole 807 set on the upper surface of the water collection pipe 806 can effectively reduce the blockage of the water collection hole 807 by silt and other particles, and maintain smooth water flow; as the blockage problem is reduced, the water collection efficiency is improved, and more groundwater can be collected in time, thereby improving the overall performance of the system.

[0042] like Figure 3 and Figure 4 As shown, downwardly inclined protective plates 808 are provided on both sides of the water collecting pipe 806, and the protective plates 808 form a V-shaped guide groove 809 at the water collecting hole 807. The V-shaped guide groove 809 design can effectively guide the water flow toward the water collecting hole 807; after the water flow enters the guide groove 809, due to the shape of the guide groove 809, the flow will be concentrated and guided to prevent the water flow from dispersing, thereby ensuring that more water can effectively flow into the water collecting hole 807; the downwardly inclined protective plate 808 design enables the water flow entering the guide groove 809 to flow downward quickly under the action of gravity; gravity guides the water flow to reduce the possibility of stagnation in the guide groove 809 and reduces the risk of silt deposition; and; the bottom of the V-shaped design is usually narrower and wider in the middle, which helps to push particulate matter such as sediment to the edge of the groove when the water flows through, avoids its deposition near the water collecting hole 807, and maintains smooth water collection.

[0043] like Figure 4As shown, a filter 8010 is installed at the V-shaped opening of the guide groove 809 of the protective plate 808. The main function of the filter 8010 is to block larger particulate matter (such as mud, leaves and other debris), which may enter the water collection system with the water flow, causing clogging or affecting the water quality; the filter 8010 can effectively prevent debris from accumulating in front of the water collection hole 807, keep the water collection system unobstructed, allow water to pass smoothly, and avoid overflow; the design of the V-shaped opening combined with the filter 8010 can provide a larger filtering area; the water flow can enter the filter 8010 at multiple angles to improve the filtering efficiency.

[0044] like Figure 4 As shown, therefore, the filter 8010 can effectively remove suspended impurities in the water and reduce pollutants entering the water collection system, thereby improving the water quality of the final collected water, which is particularly important in scenarios for irrigation or water supply; by blocking debris, the filter 8010 can reduce the blockage of the water collection hole 807 and subsequent pipelines, and reduce the frequency and cost of cleaning and maintenance; regular replacement of the filter 8010 is also much simpler than cleaning the entire water collection system.

[0045] like Figure 3 and Figure 4 As shown, in addition, a driving motor is fixedly installed inside the sealing sleeve 803, and the output end of the driving motor is connected to a gear 8012, and one side of the gear 8012 is meshingly connected to a gear ring 8013, the inner ring of the gear ring 8013 is fixedly connected to the outer ring of the connecting sleeve 804, and the connecting sleeve 804 is connected to the water inlet pipe 7 through a bearing 8011.

[0046] like Figure 3 and Figure 4 As shown, by driving the motor, the gear 8012 drives the gear ring 8013, and the gear ring 8013 drives the connecting sleeve 804 to rotate inside the sealing sleeve 803. When the connecting sleeve 804 rotates inside the sealing sleeve 803, due to the action of centrifugal force, impurities on the connecting sleeve 804 will be thrown to the outside; this process can help clean the surface of the filter 8010 and avoid the accumulation of impurities; through the action of centrifugal force, impurities on the surface of the filter 8010 can be effectively cleaned, and the cleanliness of the filter 8010 is improved, thereby ensuring the smooth flow of water or gas.

[0047] like Figure 5As shown, the interior of the repair treatment pool 3 is provided with a built-in interlayer, and the built-in interlayer is divided into a sedimentation pool 9 and a repair pool 10 inside the repair treatment pool 3. The groundwater extends to the sedimentation pool 9 of the repair treatment pool 3 through the outlet pipe 6. The groundwater after sedimentation is pumped to the interior of the repair pool 10 by a second pumping pump 11 arranged on the repair treatment pool 3, and the groundwater enters the sedimentation pool 9 through the outlet pipe 6; in the sedimentation pool 9, the flow rate of the groundwater is slowed down, so that the suspended solid particles and impurities in the water settle to the bottom due to gravity, thereby achieving a preliminary purification effect; the clean water after sedimentation is pumped to the repair pool 10 by the second pumping pump 11 arranged on the repair treatment pool 3; in the repair pool 10, the water will be further treated to remove the remaining pollutants and contaminants in the water.

[0048] like Figure 5 As shown, an activated carbon adsorbent 12, a chemical repair layer 13 and a biological repair layer 14 are sequentially arranged inside the repair pool 10 and along the water flow guide path.

[0049] like Figure 5 and Figure 6 As shown, specifically, the chemical remediation layer 13 and the biological remediation layer 14 are existing technologies in a mature context, which are used to remove harmful impurities in groundwater, and the activated carbon adsorbent 12 includes activated carbon particles 1205 and a containing box 1201 for containing the activated carbon particles 1205, a water hole 1202 is provided inside the containing box 1201, a vibration plate 1204 and a driving member 1203 for vibrating the vibration plate 1204 are fixedly installed on the top of the containing box 1201, and the vibration plate 1204 is vibrated in the containing box 1201 filled with the activated carbon particles 1205 through the driving member 1203.

[0050] like Figure 5 and Figure 6 As shown, activated carbon has a high specific surface area and rich pore structure, and can effectively adsorb harmful impurities, dissolved gases and organic pollutants in water; the activated carbon particles 1205 react with harmful substances in water through their physical and chemical properties; the vibration plate 1204 in the containing box 1201 generates vibrations through the driving member 1203, which can enhance the movement of the activated carbon particles 1205 in the water flow and promote their full contact with pollutants in the water body; the vibration increases the redistribution and fluidity of the particles, thereby improving the adsorption efficiency of the activated carbon.

[0051] like Figure 5 and Figure 6As shown, therefore, the vibration effect can increase the contact time and opportunity between activated carbon and pollutants in water, improve adsorption efficiency, and effectively enhance the ability to remove harmful substances; by maintaining the high fluidity and activity of activated carbon particles 1205, the risk of clogging is reduced, thereby extending the service life of activated carbon, reducing replacement frequency and related costs; the combination of three-layer filtration (adsorption, chemical and biological remediation) measures can quickly and effectively remove various types of pollutants, significantly improving the overall water treatment efficiency.

[0052] like Figure 6 As shown, a plurality of vibration plugs 1206 are provided at the bottom of the vibration plate 1204. The vibration plugs 1206 are serpentine structures and are inserted in the containing box 1201. When the driving member 1203 causes the vibration plate 1204 to vibrate, the vibration will be transmitted to the activated carbon particles 1205 in the containing box 1201 through the vibration plugs 1206 at the bottom; the design of the serpentine plugs can effectively disperse the vibration, so that the vibration wave produces a more uniform vibration effect in the containing box 1201; the serpentine structure enhances the turbulence of the water flow by changing the water flow path; the fluctuating water flow can break the aggregation between the activated carbons, increase the freedom of movement of the activated carbon particles 1205, and improve the frequency of mutual contact between the particles; and; due to its tortuous shape, the serpentine structure can cause greater disturbance to the water flow when passing through the plugs, thereby increasing the interaction area between the activated carbon and the pollutants in the water, making the pollutants in the water more easily adsorbed by the activated carbon.

[0053] like Figure 6 As shown, therefore, by improving the turbulent state of the water flow and the movement of the activated carbon particles 1205, the contact frequency between water and the activated carbon is increased, thereby improving the adsorption efficiency; the serpentine structure design helps the activated carbon particles 1205 to move freely in the holding box 1201, reducing the probability of accumulation and blockage between particles, and ensuring smooth water flow; due to the enhanced mobility of the activated carbon particles 1205, they can effectively and quickly contact the pollutants in the water; this allows the initial treatment to be completed faster, reducing the burden on the subsequent chemical and biological remediation layer 14.

[0054] like Figure 1 As shown, an oil-water separator 15 is fixedly mounted on the upper surface of the support base 1 , and an input end of the oil-water separator 15 is connected to an output end of the repair pool 10 .

[0055] like Figure 1As shown, the oil-water separator 15 mainly uses the density difference between the oil and water phases and the buoyancy principle for separation; water and oil have different densities, and oil is usually lighter than water, so oil will float on the water surface; when the oily wastewater enters the oil-water separator 15, the liquid will stand still inside the separator for a period of time to allow the oil and water to fully contact; due to the effect of gravity, the lighter oil will float to the water surface, while the heavier water will settle to the bottom; the oil-water separator 15 can effectively remove oil pollutants contained in the water, reduce the oil concentration in the water body, and thus improve the discharged water quality; by removing oil pollution, pollutants can be prevented from entering natural water bodies, protecting aquatic ecosystems, and achieving sustainable environmental development.

[0056] like Figure 1 As shown, the output end of the oil-water separator 15 is connected to a discharge pipe 16, and the discharge pipe 16 is used to discharge the purified groundwater into the ground.

[0057] Working principle: By using the first pump 5, groundwater is effectively extracted to the remediation treatment pool 3. In this process, the water flow is first transported to the remediation treatment pool 3 through the water intake 8 and the water inlet pipe 7. In the remediation treatment pool 3, the extracted groundwater undergoes necessary treatments in the activated carbon adsorption layer, the chemical remediation layer 13 and the biological remediation layer 14 in turn to restore its water quality. After treatment, the restored water quality is introduced into the oil-water separator 15 to remove oil stains, and finally the purified groundwater is discharged back to the ground through the discharge pipe 16 on the oil-water separator 15.

[0058] The negative pressure generated by the first water pump 5 causes the groundwater to flow into the system. In this process, the negative pressure causes the water to flow into the water bag 805 through the water collection hole 807 on the water collection pipe 806. The water collection bag 805 is a hollow spherical structure with a large volume, which can store a certain amount of water under negative pressure conditions. The water flow is first guided into the water collection bag 805 through the hole on the water collection pipe 806, and then flows into the water inlet pipe 7 through the connecting sleeve 804. The water collection pipe 806 is evenly distributed around the water collection bag 805, thereby effectively gathering and guiding groundwater from different directions. This design not only improves the water collection efficiency, but also ensures the effective restoration of water quality.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
