[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0020] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).
[0021] refer to Figure 1-3The present application discloses a soil device for ecological reconstruction of land reclamation in mining areas, comprising a collection section 1 for collecting contaminated soil, a slurry section 2 connected to the next station of the collection section 1 and used to convert the contaminated soil into slurry, a first treatment section 3 connected to the next station of the slurry section 2, an electric dialysis unit 6 connected to the first treatment section 3 and used to remove heavy metals in the slurry, a second treatment section 4 connected to the next station of the first treatment section 3 and used to neutralize the pH value of the slurry, a third treatment section 5 connected to the next station of the second treatment section 4 and used to add organic fertilizers and plant seeds to the slurry, and a discharge pipe 52 connected to the third treatment section 5 and used to discharge the treated slurry.
[0022] The contaminated soil in the mining area is transported to the collection section 1 by means of equipment such as shovels and excavators. At this stage, the soil is temporarily stored for subsequent treatment steps. Then, the contaminated soil is sent to the slurry section 2, where water is added to convert it into slurry. Converting the solid contaminated soil into a slurry state can make the pollutants in the soil more evenly distributed in the liquid medium, and its fluidity is enhanced, so that it can be easily transported to the next treatment unit through pipelines and pumping systems. In addition, in the electrodialysis unit 6, especially heavy metal ions, need to be in a liquid environment to be effectively separated from the mud by the action of the electric field; the mud then enters the first treatment section 3, where the electrodialysis unit 6 separates the heavy metal ions from the mud by applying an electric field; then, in the second treatment section 4, the pH value of the mud will be adjusted as needed, and limestone or other regulators will be added to neutralize the over-acidic or over-alkaline mud to ensure that the appropriate pH environment required for plant growth is achieved; finally, in the third treatment section 5, organic fertilizers and suitable plant seeds are added to the treated mud to provide the necessary nutrients for the plants and promote ecological reconstruction. After these treatments, the improved mud is discharged through the discharge pipe 52 and can be discharged back into the environment, so as to achieve the treatment of polluted soil in the mining area and ecological reconstruction.
[0023] The collecting part 1 has a first containing cavity (not shown in the figure) for containing contaminated soil. A funnel 11 is provided at the top of the collecting part 1 to guide the contaminated soil into the first containing cavity. The mud part 2 is located at the bottom of the collecting part 1. The mud part 2 has a second containing cavity (not shown in the figure) for containing contaminated soil. The mud part 2 is connected to a water adding pipe 21 for adding water to the second containing cavity.
[0024] The funnel 11 facilitates the dumping and collection of contaminated soil, so that the soil smoothly enters the first receiving chamber. Subsequently, the contaminated soil enters the mud section 2 through the bottom of the collecting section 1. In the second receiving chamber of the mud section 2, an appropriate amount of water is added to the contaminated soil through the water adding pipe 21 to convert it into mud. This process increases the fluidity and uniformity of the soil.
[0025] In some embodiments, the mud section 2, the first treatment section 3, the second treatment section 4 and the third treatment section 5 may be connected by a sludge pump to improve the transportation capacity of the mud.
[0026] The cavity wall of the second accommodating cavity is also rotatably connected with a plurality of spiral stirring rods for stirring the contaminated soil in the second accommodating cavity. The spiral stirring rods rotate during the water addition process to stir the contaminated soil in the second accommodating cavity, ensuring that the soil and the added water are fully mixed to form a uniform slurry.
[0027] The spiral stirring rod is a prior art, and the spiral stirring rod can be driven by a motor.
[0028] The first treatment section 3 has a third accommodating chamber 31 for accommodating mud, and there are multiple electric dialysis units 6. The multiple electric dialysis units 6 are connected to the cavity wall of the third accommodating chamber 31, and the multiple electric dialysis units 6 are arranged in sequence from the mud section 2 to the second treatment section 4. The anode 61 and the cathode 62 of the electric dialysis unit 6 are respectively arranged on two opposite side walls of the third accommodating chamber 31, and the anode 61 and the cathode 62 are respectively surrounded by the cavity wall of the third accommodating chamber 31 through an ion exchange membrane 63 to form an isolation chamber 64 for collecting adsorbed heavy metal ions.
[0029] Multiple electrodialysis units 6 are arranged in sequence along the direction of mud flow, ensuring that heavy metal ions in the mud can be effectively removed. During the electrodialysis process, an electric field is applied to cause the heavy metal ions in the mud to move toward the corresponding electrodes. The anode 61 attracts negative ions (such as sulfate, chloride ions, etc.), while the cathode 62 attracts positive ions (such as heavy metal ions such as copper, lead, zinc, etc.). The ion exchange membrane 63 allows specific ions to pass through while blocking other particles, thereby separating heavy metal ions from other components of the mud. The design 43pH in the isolation chamber 64 ensures that these ions are effectively collected and isolated, preventing them from re-entering the mud flow.
[0030] The electrodialysis unit 6 realizes the adsorption of heavy metal ions through electrodialysis technology. Those skilled in the art can use common electrodialysis equipment to achieve the purpose of this application.
[0031] After long-term use, the solution in the isolation chamber 64 can also be replaced.
[0032] The second processing part 4 has a fourth accommodating chamber 42 for accommodating mud. The second processing part 4 is also connected to a liquid storage tank 41 for adding alkali solution or acid solution into the fourth accommodating chamber 42. The second processing part 4 is connected to a controller. The cavity wall of the fourth accommodating chamber 42 is connected to a pH meter 43 for monitoring the pH value of the mud in the fourth accommodating chamber 42. The pH meter 43 and the liquid storage tank 41 are both electrically connected to the controller.
[0033] In order to ensure soil recovery and plant growth, the pH value of the mud must be adjusted to an appropriate level. The pH meter 43 continuously monitors the pH value of the mud and sends the data to the controller. When the pH value of the mud deviates from the target range, the controller instructs the liquid storage tank 41 to release an appropriate amount of alkaline solution or acid solution to adjust the pH value of the mud.
[0034] The third processing part 5 has a fifth containing chamber (not shown in the figure) for containing mud, and the second processing part 4 is also connected to a storage box 51 for adding organic fertilizers and plant seeds into the fifth containing chamber.
[0035] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
[0036] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
