DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] In order to solve the technical problem of how to make the medicinal liquid diffuse quickly in the soil layer, the utility model provides a groundwater remediation system, which can promote the flow of groundwater, increase the diffusion speed of the medicinal liquid in the soil layer, and thus improve the work efficiency of groundwater remediation and management.

[0023] It should be noted that the groundwater remediation system of the present invention is used for but not limited to groundwater pollution control, etc. For the convenience of explanation, in the present invention, only the application of the groundwater remediation system to groundwater pollution control is used as an example for explanation. The principles of applying the groundwater remediation system to other types of equipment are essentially the same as those applied to groundwater pollution control, and will not be elaborated here.

[0024] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a groundwater remediation system in one embodiment of the present invention. The groundwater remediation system includes a dosing module 100 and a pumping module 200. The dosing module 100 includes a dosing pump 110 and a dosing well 120 extending into the soil layer. The dosing pump 110 is used to transport liquid medicine into the dosing well 120. The pumping module 200 includes a pumping pump 210, a pumping pipe 220, and a pumping well 230 extending into the soil layer. One end of the pumping pipe 220 extends into the pumping well 230, and the other end thereof is connected to the pumping pump 210. The pumping pump 210 extracts the accumulated water in the pumping well 230 through the pumping pipe 220.

[0025] In this embodiment, the dosing pump 110 is first used to transport the medicine liquid into the dosing well 120, and the water pump 210 continuously extracts the accumulated water in the pumping well 230 through the pumping pipe 220, so that the water level in the pumping well 230 drops, and then the water in the soil layer will flow into the pumping well 230. As the water flows, the medicine liquid in the dosing well 120 will quickly spread into the soil layer, thereby increasing the spreading speed of the medicine liquid in the soil layer, and thus improving the work efficiency of groundwater remediation and management.

[0026] In some embodiments, the pumping module 200 further includes a support tube 240 . The outer wall of the support tube 240 is in contact with the inner wall of the pumping well 230 , and a plurality of water-permeable holes 241 are formed on the side wall of the support tube 240 .

[0027] In this embodiment, the support tube 240 is used to support the inner wall of the pumping well 230 to prevent the inner wall of the pumping well 230 from collapsing, and water in the soil layer will seep into the support tube 240 through the water-permeable holes 241 .

[0028] In some embodiments, the pumping module 200 includes a manhole cover 250 , which is used to close the opening at the top of the support tube 240 . The pumping pipe 220 passes through the manhole cover 250 and extends into the interior of the support tube 240 .

[0029] In this embodiment, the manhole cover 250 can close the support tube 240, and the pumping pipe 220 passes through the manhole cover 250 and extends into the interior of the support tube 240. When the pumping pipe 220 extracts the accumulated water inside the support tube 240, the air pressure inside the support tube 240 will be reduced. The suction force generated by the low air pressure will accelerate the speed at which the accumulated water in the soil layer flows to the pumping well 230, thereby further accelerating the diffusion speed of the liquid medicine.

[0030] In some embodiments, the medication module 100 further includes a medication mixing box 130 , and the liquid inlet end of the medication pump 110 is connected to the medication mixing box 130 .

[0031] In this embodiment, the medicine powder and water can be mixed in the medicine mixing box 130 to prepare a medicine liquid. Finally, the medicine liquid in the medicine mixing box 130 will be pumped to the direct medicine well 120 by the medicine pump 110.

[0032] Based on the above embodiments, in some embodiments, the water outlet of the water pump 210 is connected to the medicine mixing tank 130 .

[0033] In this embodiment, since the water outlet of the water pump 210 is connected to the medicine mixing tank 130, the accumulated water pumped by the water pump 210 can be used for preparing the medicine solution.

[0034] In some embodiments, the water pumping module 200 includes a three-way valve 260 and a return pipe 270, and the three-way valve 260 is respectively connected to the liquid inlet end of the water pump 210, the return pipe 270 and the medicine mixing box 130, and the three-way valve 260 can make the liquid inlet end of the water pump 210 separately connected to the return pipe 270 and the medicine mixing box 130.

[0035] It is understood that the total amount of accumulated water pumped by the pump 210 is far greater than the amount of water required to prepare the drug solution in the drug mixing tank 130. Therefore, it is not necessary to introduce all the accumulated water into the drug mixing tank 130. When it is necessary to introduce the accumulated water into the drug mixing tank 130, the three-way valve 260 can be controlled to connect the drug mixing tank 130 and the liquid inlet of the pump 210. When it is not necessary to introduce the accumulated water into the drug mixing tank 130, the three-way valve 260 can be controlled to connect the return pipe 270 and the liquid inlet of the pump 210, and the accumulated water can be introduced into the drug dosing well 120, thereby accelerating the flow of groundwater.

[0036] Based on the above embodiments, in some embodiments, the three-way valve 260 is connected to the top of the medicine mixing box 130.

[0037] In this embodiment, since the three-way valve 260 is connected to the top of the medicine mixing box 130 , it can effectively prevent the medicine liquid in the medicine mixing box 130 from flowing back to the three-way valve 260 .

[0038] In some embodiments, the pumping module 200 further includes a filter 280 . The filter 280 is installed at one end of the pumping pipe 220 extending into the pumping well 230 .

[0039] In this embodiment, the filter 280 can filter impurities to prevent a large amount of impurities from flowing into the water extraction pipe 220 .

[0040] Based on the above embodiments, in some embodiments, the filter 280 is a bag filter 280 .

[0041] In some embodiments, there are multiple dosing wells 120 , and the multiple dosing wells 120 surround the pumping well 230 .

[0042] In this embodiment, multiple dosing wells 120 are used simultaneously to increase the diffusion range of the drug solution.

[0043] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0044] In the medicine mixing box 130, the medicine powder and water are mixed with each other to prepare a medicine liquid. Finally, the medicine liquid in the medicine mixing box 130 will be pressed by the medicine dosing pump 110 to the direct medicine dosing well 120. The water pump 210 continuously extracts the accumulated water in the pumping well 230 through the pumping pipe 220. The filter 280 is installed at one end of the pumping pipe 220 extending into the pumping well 230. The filter 280 can filter impurities to prevent a large amount of impurities from pouring into the pumping pipe 220. The water level in the pumping well 230 is lowered, and the water in the soil layer will flow into the pumping well 230. As the water flows, the medicine liquid in the medicine dosing well 120 will quickly spread into the soil layer, thereby increasing the spreading speed of the medicine liquid in the soil layer and improving the working efficiency of groundwater remediation and treatment.

[0045] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
