Description

Technical Field

[0001] The present invention relates to the technical field of mine groundwater remediation, and in particular to a mine groundwater heavy metal pollution remediation device. Background Art

[0002] Mine groundwater refers to water found in rock pores below the surface. More narrowly, it refers to water in saturated aquifers below the groundwater table. Mine groundwater is a crucial component of water resources. Due to its stable supply and high quality, it serves as a vital source of water for agricultural irrigation, industrial mining, and urban areas.

[0003] Heavy metal pollution refers to environmental contamination caused by heavy metals or their compounds, primarily due to human factors such as mining, waste gas emissions, wastewater irrigation, and the use of heavy metal products. Human activities increase the concentration of heavy metals in the environment beyond normal limits, leading to a deterioration in environmental quality. With the rapid development of industry and agriculture, heavy metal contamination in mine groundwater has intensified, necessitating the urgent need to address this pollution.

[0004] At present, when remediating heavy metal pollution in mine groundwater, most of the time, remediation agents are directly added to the water body, so that the remediation agents react with heavy metal ions in the water, thereby converting and removing them. However, in actual treatment, due to the flow of water and the fact that a large amount of them are often added in a certain place, not only is it easy for the remediation agent to react with the heavy metals in the water for a short time, making it difficult for them to effectively contact and react, but a large amount of remediation agents will be lost along with the repaired water body, requiring repeated addition of new remediation agents, resulting in serious waste of resources and poor remediation effects.

The side wall of the rotating rod 8 is provided with a plurality of partitions 9 in a circular array. A first motor 7 is fixed to the top of the fixed cylinder 1, and the output end of the first motor 7 extends into the fixed cylinder 1 and is connected to the rotating rod 8;

[0044] A fixing frame 4 is provided with a connecting pipe 3 between one end of the fixing frame 4 and the fixing cylinder 1, and a water outlet pipe 5 is provided at the other end of the fixing frame 4. A biological filler 41 is placed inside the fixing frame 4; based on this, microorganisms and humin can be mixed to form a repair liquid, and the filler can be soaked to form the biological filler 41. The biological filler 41 can be put into the underground water body of the mine, and deep repair can be achieved through physical adsorption and biochemical action, which effectively enhances the heavy metal removal effect.

[0045] By connecting the water inlet pipe 2 to the underground water channel of the mine, heavy metal-contaminated water can enter the fixed cylinder 1 through the water inlet pipe 2. By arranging multiple partitions 9 in a circular array in the fixed cylinder 1, it can be divided into multiple different areas. The first motor 7 drives the rotating rod 8 to rotate, so that the rotating rod 8 drives the partitions 9 to rotate, and each area can be circulated in the fixed cylinder 1, so that water can be intermittently injected into each area. At the same time as water is injected into one area, a certain amount of biological filler 41 can be added to the upper water-filled area through the discharge barrel 17. As it rotates continuously for nearly a circle, the biological filler 41 can be in contact with the water in the area for a long time, flowing and diffusing to be fully mixed.

[0053] The bottom end of the extraction pipe 22 is provided with a cover 23. Based on this, by providing the cover 23, the biological filler 41 floating and surging on the water surface can be better absorbed.

[0054] The lifting assembly includes a baffle 28 arranged at one end of the top of the fixed frame 4, a support frame 24 is fixed to the top side of the baffle 28, a cylinder 25 is provided at the top of the support frame 24, and a connecting handle 26 is connected to the bottom end of the cylinder 25, and one end of the connecting handle 26 is fixedly connected to the extraction pipe 22.

[0055] A plurality of water filtering holes 27 facing the fixing frame 4 are provided on a side of the bottom of the housing 11 close to the first connecting pipe 15 .

[0056] The connecting handle 26 is driven to move by the cylinder 25, and in conjunction with the first telescopic hose 21, the connecting handle 26 can drive the extraction pipe 22 to the water surface position in the fixed frame 4. Then, under the suction of the booster pump 20, the biological filler 41 floating in the water can be extracted and then enter the shell 11 through the first connecting pipe 15. Under the action of the multiple groups of water filtering holes 27, the water body can fall back into the fixed frame 4, and then be discharged from the second connecting pipe 16 in conjunction with the spiral blade 14, and finally fall into the discharge barrel 17 for storage.

[0057] An aeration pump 29 is provided on the top side of the baffle 28 , and the air outlet of the aeration pump 29 is symmetrically connected to two aeration pipes 30 through a valve body. The bottom ends of the two aeration pipes 30 extend into the fixed frame 4 and are provided with multiple pneumatic structures 31 .

[0058] The pneumatic structure 31 includes a branch pipe 310 arranged at the bottom end of the aeration pipe 30, and an air collecting cylinder 320 is provided at the end of the branch pipe 310. The top side of the air collecting cylinder 320 is provided with multiple support seats 330 in a circular array. The top ends of the multiple support seats 330 are rotatably connected to the air outlet pipe 350, and the top end of the air outlet pipe 350 is fixed with a support sleeve 360.

[0060] Air is input into the aeration pipe 30 through the aeration pump 29, and then the air is ejected from each group of outlet pipes 350 through the branch pipe 310, the air collecting cylinder 320 and the second telescopic hose 340, thereby supplying oxygen to the water body, so that the microorganisms on the biological filler 41 can reproduce and grow better. The movable seat 380 is driven to rise and fall by the electric push rod 40. The movable seat 380 can push and pull multiple connecting rods 370 at the same time, so that the connecting rods 370 push and pull the outlet pipes 350 to rotate on the support seat 330 through the support sleeve 360, thereby controlling the multiple groups of outlet pipes 350 on the air collecting cylinder 320 to rotate inward or outward at the same time, so that the air flow can be ejected in all directions in the water, so that the oxygen can be fully distributed. At the same time, the air flow can disturb the biological filler 41 to diffuse everywhere, so as to better mix and repair the water body.

[0061] A filter screen 6 is provided at one end of the water outlet pipe 5 close to the fixing frame 4. Based on this, by providing the filter screen 6, the biological filler 41 can be effectively prevented from flowing out of the water outlet pipe 5.
