Description

Technical Field

[0001] The present invention relates to the technical field of groundwater pollution remediation, and in particular to a groundwater pollution remediation device and method for a petrochemical industrial park. Background Art

[0002] As an important industrial production area, petrochemical industrial parks are often accompanied by the discharge of a large amount of pollutants during their production process, among which groundwater pollution is particularly prominent. At present, groundwater pollution in petrochemical industrial parks is usually treated by remediation equipment, and permeable reaction walls are the most widely used remediation equipment.

[0003] Publication No.: CN117142730B proposes a permeable reaction wall with a built-in reaction medium. Although the permeable reaction wall can conveniently and quickly replace the internal reaction medium, it still has the following defects when used:

[0004] 1. When the reaction medium is replaced in the above-mentioned permeable reaction wall, the reaction medium in the filter area is discharged into the second tank body in the wall through the valve device, and then the new reaction medium is transported to the filter area through the feeding assembly at the top of the wall. In this way, once the second tank body is full of reaction medium, the old reaction medium cannot be discharged, so the reaction medium replacement operation cannot be continued, which affects the continuous and stable use of the equipment;

[0005] 2. During the period of replacing the reaction medium in the above-mentioned permeable reaction wall, the groundwater is still in a continuous flow state, which may easily lead to the flowing groundwater not being effectively repaired by contacting with the replaced reaction medium, thereby reducing the groundwater purification effect.

[0006] To this end, we propose a groundwater pollution remediation equipment and method for petrochemical industrial parks. Summary of the invention

[0050] The water-proof structure 100 comprises:

[0051] The anti-seepage enclosure 101 is used to surround the bottom and both sides of the wall 201 to form a U shape. Both sides of the anti-seepage enclosure 101 in the groundwater flow direction are integrally inclined with water diversion expansion walls 102. The two groups of water diversion expansion walls 102 are symmetrical and extend outward away from one end of the anti-seepage enclosure 101. The groundwater is guided through the infiltration reaction wall 200 for treatment through the water diversion expansion wall 102.

[0052] Wherein, the permeable reaction wall 200 comprises:

[0053] The wall 201 has a circulation channel provided therein for groundwater to pass through;

[0054] The circulation channel of this embodiment includes:

[0055] The trapezoidal groove 202 is provided on the side of the wall 201 facing the direction of groundwater flow. The area of ​​the side of the trapezoidal groove 202 facing the water diversion expansion wall 102 is larger than the area of ​​the side away from the water diversion expansion wall 102. As the width of the trapezoidal groove 202 gradually narrows, the water pressure of the incoming groundwater can gradually increase, making it easier to pass through the assembly seat 206, thereby greatly improving the groundwater treatment efficiency.

[0056] A guide channel 203, one end of which is connected to the trapezoidal groove 202, and the other end of which passes through the other side of the wall 201;

[0057] The water distribution network 204 is disposed in the trapezoidal groove 202 and is used to allow groundwater to evenly enter the guide channel 203 .

[0058] Several groups of assembly seats 206 are sequentially arranged in the flow channel along the groundwater flow direction. One end of the assembly seat 206 movably penetrates the top wall of the flow channel, and the other end extends to the guide groove 214 provided in the bottom wall of the flow channel. A sealing strip 1 is embedded at the connection between the top wall of the flow channel and the assembly seat 206, and a sealing strip 2 is embedded at the notch of the guide groove 214 to increase the sealing of the connection between the guide groove 214 and the assembly seat 206. In actual situations, a soil cushion layer is generally laid on the upper part of the wall 201, and one end of the assembly seat 206 extends above the top of the wall 201 and the soil cushion layer.

[0059] A cavity for accommodating a reaction medium is provided in the assembly seat 206 at a position corresponding to the flow channel. The reaction medium can be provided according to actual needs, such as elemental iron, nano-iron, degradable microorganism attachment filler, zeolite, peat, activated carbon, limestone or composite filler, etc., which is not limited here.

[0060] A through hole communicating with the cavity is provided on one side outer wall of the assembly seat 206, and a cover plate 212 is detachably provided at the through hole. The cover plate 212 and the assembly seat 206 can be detachably connected by a snap-on structure or a bolt structure. Through holes communicating with the cavity are provided at positions of the outer walls of the assembly seat 206 and the cover plate 212 corresponding to the flow channel, so that water flowing in the flow channel can enter the cavity and contact the reaction medium.

[0061] The method for remediating groundwater pollution using the above-mentioned remediation equipment comprises the following steps:

[0062] S1: The repair equipment is deployed at a designated location of groundwater flow in the petrochemical industrial park. When the groundwater flows, it enters the water-blocking structure 100 and then enters the flow channel inside the wall 201 from one side thereof;

[0063] S2: When the groundwater flows in the circulation channel, it enters the cavity of each assembly seat 206 through the through hole, reacts with the reaction medium in the cavity and is purified. The purified groundwater is discharged from the other side of the wall 201; after long-term use, the assembly seat 206 can be disassembled upward from the wall 201 from the top of the wall 201, and the reaction medium in the cavity of the assembly seat 206 can be replaced by opening the cover plate 212.

[0064] Example 2

[0065] Please refer to the attached Figure 3 -Attached Figure 8 On the basis of the first embodiment, the water inlet end of the circulation channel of this embodiment and the upper and lower inner walls on one side of the assembly seat 206 are provided with a groove body, and a closing mechanism for connecting several groups of assembly seats 206 is provided in the groove body. The closing mechanism is connected to the assembly seat 206 and is used to close the circulation channel when the assembly seat 206 is upward to a preset position; in this way, when the reaction medium in the assembly seat 206 is replaced, groundwater will not enter the circulation channel, thereby avoiding the decrease in groundwater purification effect due to the replacement of the reaction medium.

[0066] Preferably, the closing mechanism of this embodiment includes:

[0067] The sealing plate 1 224 and the sealing plate 226 are movably inserted in the upper and lower groove bodies respectively. The top of the sealing plate 1 224 is connected to the groove bottom of the top groove body through the elastic member 3 225. The elastic member 3 225 is, for example, a spring. The top of the sealing plate 1 224 is connected to the sealing plate 226 after passing through the upper groove body through the pull rope 1 227, which is used to pull the sealing plate 226 to move upward when the sealing plate 1 224 moves downward. Furthermore, a guide roller group 232 for guiding the pull rope 1 227 is provided in the upper groove body and above the sealing plate 1 224. The pull rope 1 227 passes around the guide roller group 232 and then passes through the upper inner wall of the circulation channel, and then is connected to the sealing plate 226. The guide roller group 232 includes a plurality of groups of rotatable guide rollers.

[0068] The second pull rope 228 has one end connected to the bottom of the first sealing plate 224, and the other end movably penetrates the second sealing plate 226 and extends to the lower groove body to connect the movable plate 229. The second sealing plate 226 is penetrated from top to bottom to open a movable opening for the second pull rope 228 to pass through, so that when the second pull rope 228 is pulled, it will not be affected by the second sealing plate 226. The lower groove body can be set in a Z shape. The movable plate 229 is slidably arranged in the lower groove body and connected to the inner wall of one side of the lower groove body through the fourth elastic member 230. The movable plate 229 can be specifically located in the transverse section cavity at the lower part of the lower groove body. The fourth elastic member 230 is, for example, a spring;

[0069] When the movable plate 229 moves, the closing plate 1 224 is pulled downward by the pull rope 228, and when the closing plate 1 224 moves downward, the closing plate 226 is pulled upward by the pull rope 1 227. The lower tank body is provided with a guide roller group 232 for guiding the pull rope 228.

[0070] A plurality of connecting mechanisms are movably disposed in the plurality of guide grooves 214, respectively, and are used to connect one end of the pull rope 3 231 and the other end of the assembly seat 206, and the other end of the pull rope 3 231 extends into the lower groove body and is connected to the other side of the movable plate 229;

[0071] When the assembly seat 206 at any position is upward, it can drive the connection mechanism connected thereto, and then pull the moving plate 229 to move in the lower groove body through the connection mechanism and the corresponding pull rope 3 231, while the pull rope 3 231 at other positions is relaxed for adaptive adjustment;

[0072] When the assembly seat 206 moves upward, the connecting mechanism pulls the movable plate 229 through the pull rope 3 231 to move. When the movable plate 229 moves, it pulls the sealing plate 1 224 through the pull rope 228. The sealing plate 1 224 pulls the sealing plate 2 226 through the pull rope 1 227. When the connecting mechanism moves upward to a preset position, the opposite ends of the sealing plate 1 224 and the sealing plate 2 226 contact each other to close the flow channel.

[0073] Example 3

[0074] Please see attached Figure 4 -Attached Figure 8 Based on the second embodiment, the connection mechanism of this embodiment includes:

[0075] The movable plate 213 is movably arranged in the guide groove 214 and connected to the pull rope three 231. A guide roller group 232 for guiding the pull rope three 231 is also arranged in the guide groove 214 and below the movable plate 213. An assembly cavity 217 is arranged in the movable plate 213, and a through hole communicating with the assembly cavity 217 is penetrated through the top of the movable plate 213. An arc piece 1 222 is symmetrically integrated on the inner wall of the through hole. A movable rod 216 is inserted in the through hole and located on the inner side of the arc piece 1 222. One end of the movable rod 216 movably penetrates the assembly seat 206 and extends into the cavity to be connected to the inner sleeve 207. The other end of the outer wall of the movable rod 216 and located below the arc piece 1 222 is provided with an arc piece 223 cooperating therewith. One end of the inner sleeve 207 is rotatably connected to the bottom wall of the cavity through a bearing, and the other end movably penetrates the top of the assembly seat 206.

[0076] When the arc piece 1 222 and the arc piece 223 are aligned, the inner sleeve 207 drives the assembly seat 206 and the movable plate 213 upward; when the arc piece 1 222 and the arc piece 223 are staggered, the inner sleeve 207 drives the assembly seat 206 and the movable rod 216 upward relative to the movable plate 213, and the movable rod 216 is separated from the movable plate 213.

[0077] The working principle is as follows: when the reaction medium needs to be replaced, the inner sleeve 207 in the corresponding assembly seat 206 is pulled, and the inner sleeve 207 drives the assembly seat 206 and the movable plate 213 upward. After the movable plate 213 is upward to a preset position, the inner sleeve 207 is rotated to stagger the arc piece 1 222 and the arc piece 2 223, and then the inner sleeve 207 is pulled, and the inner sleeve 207 drives the assembly seat 206 and the movable rod 216 upward relative to the movable plate 213 until the cavity in the assembly seat 206 is above the wall 201. The reaction medium in the cavity can be replaced by opening the cover plate 212.

[0078] Example 4

[0079] Please refer to the attached Figure 5 -Attached Figure 6On the basis of the third embodiment, magnetic clamping rods 219 are symmetrically arranged on both sides of the assembly cavity 217 of this embodiment, and an assembly rod 218 is arranged between the two sets of magnetic clamping rods 219. One end of the assembly rod 218 extends into the through hole and is fixedly connected to the movable rod 216. As the movable rod 216 rotates and moves up and down, the outer walls of both sides of the assembly rod 218 are embedded with magnetic blocks 220 that attract the magnetic clamping rods 219 and move inward. The magnetic blocks 220 and the magnetic clamping rods 219 are mutually oppositely polar magnetic structures, and the magnetic blocks 220 correspond to the arc piece 1 222 and the arc piece 2 223. When the magnetic clamping rod 219 is in the assembly cavity, the outer end of the magnetic clamping rod 219 is in the assembly cavity, and then the movable plate 213 moves up and down. The magnetic block 220 is staggered with the magnetic clamping rod 219 when the arc piece 1 222 and the arc piece 223 are staggered. The outer wall of the magnetic clamping rod 219 is provided with an elastic member 221 which drives the magnetic clamping rod 219 to move outward when the magnetic block 220 and the magnetic clamping rod 219 are staggered. The elastic member 221 is a spring, and the inner wall of the guide groove 214 is provided with a clamping hole for the magnetic clamping rod 219 to be inserted when the movable plate 213 moves upward to a preset position.

[0080] The working principle is as follows: after the assembly seat 206 and the movable plate 213 are driven upward to the preset position by the inner sleeve 207, the arc piece 1 222 and the arc piece 2 223 are gradually staggered by rotating the inner sleeve 207. At this time, the magnetic block 220 is gradually staggered with the magnetic clamping rod 219, and then the magnetic clamping rod 219 is gradually reset into the clamping hole under the action of the elastic member 221. After the arc piece 1 222 and the arc piece 223 are completely staggered, the inner sleeve 207 is pulled again. The inner sleeve 207 drives the assembly seat 206, the movable rod 216 and the assembly rod 218 upward relative to the movable plate 213. Under the fixation of the magnetic clamping rod 219 and the clamping hole, the movable plate 213 will not be pulled downward and reset under the action of the elastic member 4 230, thereby ensuring the closed stability of the circulation channel.

A water inlet hole connected to the cavity and the recess 215 is provided on the outer wall of the inner sleeve 207. The groundwater entering the cavity also enters the recess 215 through the water inlet hole, and contacts with the reaction medium in the recess 215 to produce a reaction, so as to perform water pollution remediation and purification. The reaction medium in the recess 215 is in contact with the reaction medium in the cavity. That is, if the reaction medium in the cavity is activated carbon, the reaction medium in the recess 215 is also activated carbon. An operation plate 209 is fixedly provided on the top of the detection rod 208. A movable opening is provided on the operation plate 209, and a fixed block 210 is slidably provided in the movable opening.

An insert block (not shown in the figure) is provided on one side of the fixed block 210, and a slot (not shown in the figure) for inserting the insert block is provided on the outer wall of the inner sleeve 207.

[0083] An operating ring 205 is provided on the top of the assembly seat 206 so that the user can remove the assembly seat 206 from the top of the wall 201 manually or using external equipment;

[0084] The working principle is as follows: in daily use, the user can press the fixed block 210 to make the plug-in block disengage from the slot, and then pull the operating handle, the operating handle drives the detection rod 208 upward, so that the reaction medium in the recess 215 is upward, and the state of the reaction medium is judged whether it is saturated by visual observation or detection of the reaction medium. If it is saturated, the detection rod 208 can be pushed downward to reset, so that the plug-in block enters the slot, and then the operating handle is pulled, the operating handle drives the inner sleeve 207 upward, and the inner sleeve 207 drives the assembly seat 206 and the movable plate 213 upward. After the movable plate 213 moves upward to the preset position, the operating handle is rotated to drive the inner sleeve 207 so that the arc piece 1 222 and the arc piece 223 are staggered, and then the operating handle is pulled, and the operating handle drives the assembly seat 206, the movable rod 216 and the assembly rod 218 upward relative to the movable plate 213 until the cavity in the assembly seat 206 is above the wall 201, and the reaction medium in the cavity can be replaced by opening the cover plate 212.
