[0002] Groundwater pollution is an important issue in current environmental governance. The sources of pollutants include industrial wastewater, agricultural chemicals, and urban domestic sewage. Remediation technologies are mainly divided into in-situ remediation and ex-situ remediation. In-situ remediation is increasingly widely used due to its advantages such as no excavation, minimal environmental disturbance, and low risk of secondary pollution. In-situ remediation usually involves injecting remediation agents into the soil and groundwater through injection wells to degrade, transform, or remove pollutants. Existing injection well technologies include high-pressure rotary jetting, fixed injection wells, and direct push injection. Among them, fixed injection wells dominate due to their ease of operation and low cost.

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] Example 1: Reference Figures 1-11 A groundwater pollution remediation system includes: a platform 1, a well body 2, a liquid storage tank 3, a drainage pipe 4, a liquid pump 5, a detection mechanism and a protection mechanism 6. The platform 1 is connected to the well body 2, the liquid storage tank 3, the drainage pipe 4, the liquid pump 5 and the detection mechanism. The bottom of the well body 2 is placed below the platform 1, the top of the drainage pipe 4 is connected to the bottom of the liquid storage tank 3, the drainage pipe 4 is connected to the output end of the liquid pump 5, and the other end of the drainage pipe 4 is connected to the protection mechanism 6, which is placed inside the well body 2.

[0020] The principles of the above scheme are: When the device is repairing groundwater, it is necessary to first confirm the composition of pollutants in the groundwater through a detection mechanism, and then inject chemicals into the ground to eliminate the pollutants in the groundwater. After the detection of the composition is completed, the liquid pump 5 is started to work, and the chemicals in the liquid storage tank 3 enter the protection mechanism 6 through the drainage pipe 4, and are discharged into the interior of the well body 2 through the protection mechanism 6. When the chemicals are discharged, the protection mechanism 6 is in an open state to facilitate the smooth injection of the chemicals. When the injection of the chemicals is completed, the protection mechanism 6 is in a closed state to prevent some mud and sand in the well body 2 from entering the drainage pipe 4 to prevent it from being blocked.

[0021] The beneficial effects of the above scheme are: The device is equipped with a detection mechanism to detect and determine the composition of the pollutants. Then, through the liquid storage tank 3, the drainage pipe 4 and the liquid pump 5, the reagent is smoothly and accurately injected into the bottom layer to accurately eliminate the pollution in the groundwater, thereby improving the working efficiency of the remediation system and reducing the waste of reagents. The setting of the protection mechanism 6 facilitates the protection of the drainage pipe 4, preventing mud or debris in the bottom layer from entering the drainage pipe 4 when the device is not working, and further ensures that the next time the device repairs groundwater, the agent will not be unable to be discharged.

[0022] Example 2: Reference Figures 1-11 The protection mechanism 6 includes: a storage tube 7, the other end of the drain tube 4 is connected to the top of the storage tube 7 through an annular filter screen 8, the inner wall of the annular filter screen 8 is slidably sealed with the side wall of the sealing tube 9, the top of the sealing tube 9 is set toward the drain tube 4, the bottom of the sealing tube 9 is connected to the top of the baffle 10, and the bottom of the baffle 10 is connected to the bottom wall of the storage tube 7 through a spring 11.

[0023] The principles of the above scheme are: When the device is injecting the agent, the agent enters the interior of the sealing tube 9 through the drainage pipe 4. After the pressure on the sealing tube 9 and the baffle 10 increases, they move downward in the receiving tube 7. At the same time, the spring 11 is compressed. When the pressure reaches a certain level, the sealing tube 9 stops sealing the annular filter 8, and the agent in the drainage pipe 4 can be discharged into the formation through the annular filter 8. When the medicine in the discharge pipe 4 is discharged, the pressure on the sealing pipe 9 and the baffle 10 is reduced. Under the elastic force of the spring 11, the height of the sealing pipe 9 rises, thereby sealing the annular filter 8 again. The beneficial effects of the above scheme are: The side of the sealing tube 9 seals the annular filter 8 to prevent the mud or impurities in the formation from entering the drainage pipe 4 through the annular filter 8 after the device finishes filling the reagent; At the same time, since a large amount of reagents need to be discharged during pollution remediation, the diameter of the drain pipe 4 will be increased appropriately. When the amount of reagents to be discharged increases to a certain level, the general one-way valve cannot control the flow direction of the reagents in the drain pipe 4. Therefore, a sealing tube 9 is provided to seal with the annular filter 8, which reduces the difficulty of manufacturing the device and reduces the manufacturing cost of the device, further increasing the practicality of the device during use.

[0024] Example 3: Reference Figures 1-11 Two quartz sand filter layers and two bentonite sealing layers are longitudinally spaced apart in the well body 2. The annular filter screen 8 is arranged in a quartz sand filter layer. The quartz sand filter layer and the bentonite sealing layer are arranged alternately. The quartz sand filter layer is arranged below the bentonite sealing layer. The side wall of the well body 2 is provided with multiple ends of through holes 12. The other end of the through hole 12 is opened on the inner wall of the well body 2 and is arranged toward the quartz sand filter layer.

[0025] The principles and beneficial effects of the above scheme are: When injecting the reagent, the reagent discharged from the annular filter 8 first enters the quartz sand filter layer, and then enters the formation through the through hole 12 opened on the well body 2. The setting of the quartz sand filter layer facilitates the flow of the reagent, and the setting of the bentonite sealing layer can prevent the backflow phenomenon in the quartz sand filter layer, thereby ensuring the utilization rate of the reagent after injection.

[0026] Example 4: Reference Figures 1-11 The platform 1 is connected to an aeration pipe 13 and an exhaust pipe 14, the aeration pipe 13 is connected to an air pump 15, the end of the aeration pipe 13 away from the top surface of the platform 1 is connected to an air filter tank 16, and the other end of the aeration pipe 13 is placed in a quartz sand filter layer.

[0027] The principles and beneficial effects of the above scheme are: Before the injection of the reagent, the type of pollutants in the formation must be determined. At this time, the air pump 15 is started, and the air in the environment enters the aeration pipe 13 through the air filter tank 16. The air is transported by the aeration pipe 13 and enters a quartz sand filter layer. Since the quartz sand filter layer itself has a certain fluidity for the fluid, it contains a certain amount of sewage. The air pressure output by the aeration pipe 13 causes the pollutants in the quartz sand filter layer and the volatiles of the sewage to flow upward, reducing the difficulty of obtaining the pollutant components. At the same time, two quartz sand filter layers and two bentonite sealing layers are longitudinally spaced apart in the well body 2. The quartz sand filter layers and the bentonite sealing layers are arranged alternately, and the quartz sand filter layer is arranged below the bentonite sealing layer to prevent pollutants from escaping directly from the well body 2. Furthermore, a layer of cement can be sealed on the uppermost bentonite sealing layer to further ensure that there is no gas leakage during the detection of the device, thereby ensuring the safety of the device during operation and protecting the surrounding staff. The setting of the air filter tank 16 can prevent impurities and dust in the outside air from entering the quartz sand filter layer, thereby preventing the quartz sand filter layer or the stratum around the well body 2 from being contaminated or blocked, thereby ensuring the fluidity of the agent during injection, preventing the agent from being locally blocked, and thus avoiding the occurrence of incomplete repair.

[0028] Example 5: Reference Figures 1-11 The exhaust pipe 14 is connected to a vacuum pump 17, the air pump 15 and the vacuum pump 17 are both connected to the platform 1, the end of the exhaust pipe 14 is placed in another quartz sand filter layer, and the end of the exhaust pipe 14 is placed above the other end of the aeration pipe 13.

[0029] The principles and beneficial effects of the above scheme are: After air is input into the aeration pipe 13, the volatile pollutants first pass through the quartz sand filter layer where the aeration pipe 13 is located. At this time, since the drainage pipe 4 is not filled with the agent, the sealing pipe 9 seals the annular filter 8, so the volatiles and gas will not enter the drainage pipe 4. Therefore, no bubbles will appear when the agent is injected. When the liquid is injected, the bubbles will be broken due to the closing of the valve device and the change in the liquid flow rate. At this time, the impact of the broken bubbles on the pipeline structure is far greater than the harmful water hammer effect. Therefore, the elimination of bubbles can avoid the phenomenon of pipeline rupture and vibration. The elimination of bubbles can avoid the occurrence of alternating blockage caused by intermittent flow of gas and liquid, and thus prevent the liquid from causing severe impact on the inside of the pipeline after the bubbles flow through, thereby protecting the bends, valve components and flanges of the pipeline; It can further avoid the occurrence of cavitation, thereby extending the service life of the pipeline; When the drain pipe 4 is not in use, the bottom is in a closed state. Therefore, corrosive gases such as hydrogen sulfide and carbon dioxide generated by pollutants will not enter the interior of the drain pipe 4. Therefore, the phenomenon of corrosive liquids being produced after the harmful gases combine with water will not occur, thereby extending the service life of the drain pipe 4 and ensuring that it will not be broken due to corrosion during use, thereby ensuring that the medicine is effectively injected; Under the action of the air pressure in the aeration pipe 13, the volatile substances pass through the bentonite sealing layer into another quartz sand filter layer, and are then collected through the exhaust pipe 14. To improve the collection efficiency, the vacuum pump 17 is turned on to reduce the air pressure inside the exhaust pipe 14, thereby increasing the collection efficiency of volatile substances and gases.

[0030] Example 6: Reference Figures 1-11 The other end of the exhaust pipe 14 is connected to one side of the gas-liquid separator 18, the gas-liquid separator 18 is connected to the top of the platform 1, the other side of the gas-liquid separator 18 is connected to the end of the exhaust pipe 19, and the other end of the exhaust pipe 19 is connected to the end of the detection box 20 in the detection mechanism, and a gas detection element is connected in the detection box 20.

[0031] The principles and beneficial effects of the above scheme are: The volatile substances and gases entering the exhaust pipe 14 are separated from the water by the gas-liquid separator 18, and then the gases and volatile substances enter the detection box 20 through the exhaust pipe 19. The gas detection elements therein are used to perform specific measurements on the composition and type of pollutants, and then determine the type and composition of the reagents to be used, thereby improving the utilization rate of the reagents during sewage treatment and improving the efficiency of sewage treatment.

[0032] Example 7: Reference Figures 1-11 The other end of the detection box 20 is connected to the end of a release pipe 21 , a one-way valve is provided in the release pipe 21 , and the other end of the release pipe 21 is arranged toward the top of the platform 1 .

[0033] The principles and beneficial effects of the above scheme are: While the detection box 20 is detecting the pollutant components, the detected gas can be discharged to the outside of the detection box 20 through the release tube 21. Since the other end of the release tube 21 is set toward the top of the platform 1, when it rains in the environment where the device is located, moisture will not enter the detection box 20. At the same time, a one-way valve is provided in the release tube 21, which can further improve the sealing effect inside the detection box 20.

[0034] Example 8: Reference Figures 1-11The other end of the exhaust pipe 19 is connected to the end of the exhaust pipe 22 through the dust removal assembly. The other end of the exhaust pipe 22 is slidably connected to a flange 23. The end face of the flange 23 is connected to the ends of multiple plug rods 24. The plug rods 24 are plugged into the flange 25. The flange 25 is connected to the end of the exhaust pipe 3 26. The other end of the exhaust pipe 22 is adjacent to the end of the exhaust pipe 3 26. The other end of the exhaust pipe 3 26 is connected to the end of the detection box 20. The flange 23 is in contact with the flange 25. The other end face of the flange 23 away from the plug rod 24 is connected to a rack 27. The rack 27 is meshed with the gear 28, and the gear 28 is rotatably connected to the exhaust pipe 22 through the rotating shaft 29.

[0035] The rotating shaft 29 is connected to a worm wheel 30 , which is meshed with a worm 31 , and the worm 31 is rotatably connected to the second exhaust pipe 22 .

[0036] The principles and beneficial effects of the above scheme are: When the exhaust pipe 22 needs to be disassembled, the worm 31 is rotated forward, and the worm 31 drives the worm wheel 30 meshing with it to rotate, and then the shaft 29 and the gear 28 rotate. Under the sliding cooperation of the exhaust pipe 22, the rack 27 meshing with the gear 28 drives the flange 23 and the insertion rod 24 to move away from the detection box 20, and the insertion rod 24 ends the plug-in cooperation with the flange 25, and the flange 23 and the flange 25 end the sealing cooperation; When the exhaust pipe 22 needs to be installed, the flange 23 is adjusted to contact and cooperate with the flange 25, and the worm 31 is reversed. The worm 31 drives the worm wheel 30 connected thereto to rotate in the opposite direction, and then the shaft 29 and the gear 28 rotate in the opposite direction. Under the sliding cooperation of the exhaust pipe 22, the rack 27 connected to the gear 28 drives the flange 23 and the plug rod 24 to move toward the detection box 20, and the plug rod 24 is plugged into and cooperated with the flange 25; Since the worm wheel 30 is meshed with the worm 31, the worm 31 can lock the worm wheel 30. Therefore, when it is necessary to keep the exhaust pipe 2 22 and the exhaust pipe 3 26 sealed, it is only necessary to rotate the worm 31 into place to maintain the sealing effect between the components, and at the same time, the efficiency of disassembly and installation between the components can be improved.

[0037] Example 9: Reference Figures 1-11The dust removal component includes: a sleeve 32, the other end of the exhaust pipe 19 is connected to the side wall of the sleeve 32, and a plug 33 is rotatably and sealedly connected inside the sleeve 32. A plurality of filter holes 34 are arranged in a circumferential array on the side wall of the plug 33. The filter holes 34 are concentrically arranged with the exhaust pipe 19, and each filter hole 34 is connected to a filter screen 35. The exhaust pipe 22 is rotatably matched with the plug 33. The other end of the exhaust pipe 22 is placed in the plug 33 and is arranged toward the other end of the exhaust pipe 19, and is slidably and sealedly matched with the inner wall of the plug 33. The bottom of the exhaust pipe 22 is connected to the side wall of the sleeve 32 through a connecting rod 36.

[0038] The principles and beneficial effects of the above scheme are: The dry gas and volatile substances in the exhaust pipe 19 are input into the sleeve 32, and enter the exhaust pipe 2 22 through the filter 35 on the filter hole 34 in the insert pipe 33. When the pressure output by the aeration pipe 13 is high, some soil in the bentonite sealing layer will enter the exhaust pipe 14. After being dried by the gas-liquid separator 18, the soil will appear in the form of dust. In order to prevent the dust from damaging the gas detection element and ensure the accuracy of the detection results, the filter 35 is provided to intercept and collect the dust. At the same time, it can reduce the difficulty of maintenance and cleaning of the detection box 20 and improve the cleanliness of the device. The filtered gas and volatile substances enter the exhaust pipe 22. Since the exhaust pipe 22 and the inner wall of the insert tube 33 are in sliding sealing cooperation, and the insert tube 33 and the sleeve 32 are in rotational sealing cooperation, the collection efficiency of the exhaust pipe 22 for gas and volatile substances can be improved.

[0039] Example 10: Reference Figures 1-11 The exhaust pipe 19 is rotatably connected to a rotating shaft 2 37, and a plurality of fan blades 38 connected to the rotating shaft 2 37 are arranged in the exhaust pipe 19. The bottom end of the rotating shaft 2 37 is placed below the exhaust pipe 19 and is connected to a gear 2 39. The gear 2 39 is meshed with the gear 3 40. The gear 3 40 is connected to the bottom of the rotating shaft 3 41. The top of the rotating shaft 3 41 is rotatably connected to the exhaust pipe 19. The side wall of the rotating shaft 3 41 is connected to the end of the connecting rod 2 42. The other end of the connecting rod 2 42 is connected to the bottom end of the guide rod 43. The guide rod 43 slides with a U-shaped groove 45 on the side wall of the drive disk 44. The top of the plurality of U-shaped grooves 45 is arranged in a circular array on the side wall of the guide rod 43. The arc-shaped bottom end of the U-shaped groove 45 is arranged close to the rotating shaft 46 connected to the drive disk 44. The rotating shaft 46 is rotatably connected to the bottom of the sleeve 32.

[0040] The principles and beneficial effects of the above scheme are: When gas flows in the exhaust pipe 19, air pressure is applied to the fan blades 38, and the rotating shaft 2 37 is driven to rotate the gear 2 39 clockwise to rotate synchronously. Under the cooperation of the rotating shaft 31 and the exhaust pipe 19, the gear 3 40 meshing with the gear 2 39 rotates, and the connecting rod 2 42 and the guide rod 43 rotate synchronously. Since a plurality of U-shaped grooves 45 are provided on the side wall of the driving disk 44, the U-shaped grooves 45 are slidably matched with the guide rod 43, so the guide rod 43 drives the driving disk 44 to rotate intermittently in the clockwise direction, and then drives the sleeve 32 to rotate intermittently through the rotating shaft 46. Therefore, after collecting dust for a period of time, the filter 35 will stop being connected to the exhaust pipe 19. At this time, another filter 35 is connected to the exhaust pipe 19, which can avoid the filter 35 from being blocked by dust due to long-term operation, avoid inaccurate detection results, and avoid the phenomenon of damage to the device caused by increased air pressure in the exhaust pipe 19. Gear 2 39 drives the rotation of connecting rod 2 42 through gear 3 40. Since the guide rod 43 connected to connecting rod 2 42 slides with the U-shaped groove 45 of the driving disk 44, the driving disk 44 rotates intermittently. At the same time, the diameter of gear 2 39 is set to be smaller than the diameter of gear 3 40. Therefore, on the basis of the intermittent movement of the driving disk 44, the rotation speed of the cannula 33 is further reduced, which not only reduces the friction between the components and extends the service life of the device, but also reduces the maintenance frequency of the device. Furthermore, the filter screen 35 can be fully utilized to collect as much dust or impurities as possible.

[0041] Example 11: Reference Figures 1-11 The second rotating shaft 37 is placed at the top above the exhaust pipe 19 and is connected to a gear 48. The teeth of the gear 48 are in contact with the ball top of the end of the push rod 49. The push rod 49 is slidably connected to the exhaust pipe 19. The push rod 49 is connected to the end of the spring 2 51 through the mounting ring 50. The other end of the spring 2 51 is connected to the top of the exhaust pipe 19. The side wall of the sleeve 32 is connected to the end of the mounting tube 52. The mounting tube 52 is coaxially arranged with a filter hole 34. The inner wall of the mounting tube 52 is slidably connected with a slider 53. The end surface of the slider 53 is connected to the end of a rubber rod 54. The other end of the rubber rod 54 is arranged toward a filter screen 35. The push rod 49 is slidably connected to the mounting tube 52. The other end of the push rod 49 is placed in the mounting tube 52 and is provided with a ball top 2 55. The center of the ball top 2 55 is arranged toward the side of the other end surface of the slider 53. The other end surface of the slider 53 is connected to the inner wall of the mounting tube 52 through a spring 3 56. The bottom of the mounting tube 52 is connected to the top of the discharge pipe 47.

[0042] The principles and beneficial effects of the above scheme are: When the rotating shaft 37 rotates clockwise, the gear 48 rotates synchronously, and the teeth of the gear 48 contact and cooperate with the ball top at the end of the push rod 49. The push rod 49 moves toward the detection box 20. The mounting ring 50 moves synchronously to drive the spring 2 51 to lengthen. After rotating through one tooth, the push rod 49 is reset under the elastic force of the spring 2 51 and prepares for contact with the next tooth of the gear 4 48. The reciprocating motion of the push rod 49, the push rod 49 is slidably connected with the mounting tube 52 and the exhaust pipe 19, and the ball top 2 55 at the other end thereof is synchronously reciprocated. When the ball top 2 55 moves toward the detection box 20, it contacts and cooperates with the side of the other end surface of the slider 53. The slider 53 drives the rubber rod 54 to contact and cooperate with a filter 35. The spring 3 5 6 is stretched, and when in contact, the rubber rod 54 impacts the filter 35 to clean the dust thereon, and the dust and powder on the filter 35 are discharged through the discharge pipe 47 connected to the bottom of the mounting tube 52, and then the push rod 49 drives the ball top 2 55 to reset, and under the elastic force of the spring 3 56, the slider 53 drives the rubber rod 54 to reset. The setting of the rubber rod 54 ensures that the filter 35 will not be damaged when it is impacted to clean the dust; the setting of the push rod 49 in the mechanism greatly reduces the setting of the power components, which not only reduces the cost but also improves the practicality of the device; the collection of dust on the filter 35 further increases the ability of the device to work independently and avoids manual cleaning of the device.
