Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a device for treating acid mine wastewater by utilizing a biological bacteria coupled membrane method. Background Art

[0002] Acidic mine wastewater is a serious source of environmental pollution generated during mining and smelting. This type of wastewater usually contains high concentrations of heavy metal ions, sulfates and other inorganic pollutants, has a low pH value, is highly corrosive, and poses a serious threat to water bodies, soil and ecosystems. Therefore, this type of wastewater needs to be treated. In recent years, membrane separation technology has been widely used in the field of wastewater treatment due to its advantages such as high efficiency, energy saving and environmental protection. The biological bacteria coupled membrane method for treating wastewater is a wastewater treatment method that combines biological treatment with membrane separation technology. Its water mainly utilizes the metabolic activities of microorganisms (biological bacteria) to convert organic matter and inorganic pollutants in wastewater into harmless or low-toxic substances, and through the separation effect of membrane technology, it further removes suspended matter, colloids, soluble organic matter and microorganisms in wastewater, thereby achieving the purpose of purifying wastewater.

[0003] However, as for the existing devices for treating acid mine wastewater using the biological bacteria coupled membrane method, when it flows into the treatment pool through the flow channel, there will be a large number of floating objects (such as plastic bags, bottles and cans) in the water body and on the water surface. At present, they are intercepted by a fence structure, and there is no automatic fishing structure. As time goes by, the floating objects will accumulate more and more, and people need to go into the water to salvage and clean the floating objects. The steps are cumbersome and very troublesome, and the practicality is poor. Summary of the invention

Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please refer to Figures 1 to 8 As shown:

[0036] Embodiment 1: The present invention provides a device for treating acid mine wastewater by using a biological bacteria coupled membrane method, comprising a flow channel component 1, the flow channel component 1 comprising a wastewater flow channel 101 and a treatment tank 102, the wastewater flow channel 101 being arranged at the top of one side of the treatment tank 102, the acid mine wastewater flows into the treatment tank 102 through the wastewater flow channel 101 to implement the operation of treating the wastewater by the biological bacteria coupled membrane method; and further comprising an interception component, the interception component comprising an interception mechanism 2 and a fishing mechanism 3;

[0037] The interception mechanism 2 includes a fixed seat 201, a linkage rod 202, a fixed interception rod 203 and a follower block 204. The fixed seat 201 is fixedly installed inside the flow channel of the wastewater flow channel 101, and the fixed interception rod 203 is vertically fixedly connected to the bottom of the fixed seat 201. The follower block 204 is fixedly installed outside the linkage rod 202.

[0038] The fishing mechanism 3 includes a driving motor 301, a driving rod 302, a lifting seat 303 and a linkage block 304. The driving motor 301 is fixedly installed on the top of the fixed seat 201, and the driving rod 302 is rotatably connected to the inside of the fixed seat 201. The rotating shaft of the driving motor 301 is transmission-connected to the top of the driving rod 302, and the lifting seat 303 is plugged into the inside of the fixed seat 201, and the linkage block 304 is plugged into the inside of the lifting seat 303.

[0039] There are two groups of fishing mechanisms 3 , and the two groups of fishing mechanisms 3 are symmetrically arranged on both sides of the fixed seat 201 , and the two ends of the linkage rod 202 are rotatably connected to the inside of the two lifting seats 303 .

[0040] In the disclosed embodiment, a fishing rod 2041 and a blocking rod 2042 are respectively provided on the side and top of the follower block 204, and the fishing rod 2041 and the blocking rod 2042 are distributed in an "L" shape, and the follower block 204 and the fixed intercepting rod 203 are staggered. When the follower block 204 is used in a horizontal state, the fishing rod 2041 is designed to be tilted upward, and the blocking rod 2042 is designed to be vertically upward. The fishing rod 2041 is arranged on the water-facing side, and the rotation axis of the linkage rod 202 is arranged on the water-receiving side. In use, the acidic wastewater generated by the mine can flow into the interior of the treatment tank 102 through the wastewater flow channel 101, and be treated by the biological bacteria coupled membrane method. The wastewater will pass through the interception mechanism 2 during the flow, so that the fixed intercepting rod 203 of the fence structure can intercept floating objects in the water body and the water surface to prevent these floating objects from entering the interior of the treatment tank 102. While stably realizing the wastewater treatment, it can also realize the separation operation between the floating objects and the water body, which is stable and convenient to use.

[0041] In the embodiment of the present disclosure, the rod body of the driving rod 302 is provided with a thread on the outside, and the driving rod 302 is screwed to the inside of the lifting seat 303 through the rod body thread. In use, the fishing mechanism 3 can automatically fish and collect the floating objects intercepted by the fixed interception rod 203, which simplifies the collection process and can be operated on the shore without going into the water. When the lifting seat 303 is in the lowest use position, the linkage rod 202 is at the bottom of the wastewater body, that is, the fishing rod 2041 and the blocking rod 2042 are both at the bottom of the intercepted floating objects. When the floating objects need to be caught and collected, the lifting seat 303 only needs to be driven upward by the driving motor 301. When the driving motor 301 rotates, it can drive the driving rod 302 to rotate synchronously. When the driving rod 302 rotates, it can drive the lifting seat 303 to move up and down inside the fixed seat 201 through the rod body thread. Therefore, the lifting seat 303 can realize the fishing and collection operations of the floating objects when it moves upward, and can automatically reset when it moves downward. It is convenient and flexible to use, and has a high degree of automation.

[0042] In the disclosed embodiment, a reset spring 3041 is provided inside the linkage block 304, and the two ends of the reset spring 3041 are respectively against the inside of the linkage block 304 and the inside of the lifting seat 303, a linkage rack 3042 is provided on the side of the linkage block 304, and a linkage gear 2021 is provided on the outside of the linkage rod 202, and the gear teeth of the linkage rack 3042 and the linkage gear 2021 are meshed for transmission. Under the action of the reset spring 3041, when the linkage block 304 is not resisted by external force, the follower block 204 is in a horizontal state. In use, when the lifting seat 303 moves upward, it can drive the linkage rod 202 to move upward synchronously, and under the action of the reset spring 3041 Under the action of , the follower block 204 is in a horizontal use state, and the fishing rod 2041 is located on the water-facing side, so when the fishing rod 2041 moves up following the follower block 204 and the linkage rod 202, the fishing rod 2041 with an upward tilt design can support the intercepted floating objects, and under the action of the blocking rod 2042, the supported floating objects will not fall. The top of the fixed seat 201 is provided with a resisting protrusion 2011, and the resisting protrusion 2011 is located directly above the linkage block 304. The flow channel component 1 also includes a collecting chute 103 and a collecting box 104. The collecting chute 103 is fixedly installed on the top of the side of the fixed seat 201, and the collecting box 104 104 is arranged on the side of the wastewater flow channel 101, the interior of the collection chute 103 is designed to be inclined toward the side of the collection box 104, and the collection box 104 is located directly below one end of the deeper trough of the collection chute 103, and the collection chute 103 is arranged on the backwater side. As the lifting seat 303 continues to move upward, the linkage block 304 will be blocked and resisted by the abutment protrusion 2011, so that the linkage block 304 cannot continue to move upward synchronously with the lifting seat 303. Thereafter, when the lifting seat 303 moves upward, the linkage block 304 will shrink toward the inside of the lifting seat 303 and compress the reset top spring 3041, and in this process, the linkage rack 3042 can be moved by the linkage gear 2021 The linkage rod 202 is driven to rotate, so that the follower block 204, the fishing rod 2041 and the blocking rod 2042 are turned upward by 180 degrees, thereby pouring the supported floating objects into the interior of the collecting chute 103 located on the back water side. Since the interior of the collecting chute 103 is inclined, these floating objects will automatically slide into the interior of the collecting box 104 for collection, which is convenient and flexible to use. After that, by controlling the lifting seat 303 to descend, under the action of the reset top spring 3041, the linkage rod 202 can automatically reverse and reset and follow the lifting seat 303 to move down to the bottom of the water body again, so as to prepare for the next collection and fishing of floating objects, with a high degree of automation.

[0043] In the disclosed embodiment, a limit stop block 3031 is provided on the side of the lifting seat 303, and a limit protrusion 2022 is provided on the outside of the linkage rod 202. This design can limit the maximum rotation angle of the linkage rod 202, thereby avoiding the phenomenon that the floating object fishing and collection functions fail due to excessive rotation of the linkage rod 202, and the use is stable.

[0044] In the disclosed embodiment, a track block 3032 is provided on the side of the lifting seat 303, and the block cross-sections of the track block 3032 and the linkage block 304 are both "T"-shaped. This design can absorb the moving trajectory of the lifting seat 303 and the linkage block 304, thereby avoiding the device from being skewed, twisted or stuck during use, and ensuring stable use.

[0045] Specific usage and function of this embodiment: In the present invention, the acidic wastewater generated by the mine can flow into the interior of the treatment tank 102 through the wastewater flow channel 101 and be treated by the biological bacteria coupling membrane method. The wastewater will pass through the interception mechanism 2 during the flow, so that the fixed interception rod 203 of the fence structure can intercept the floating objects in the water body and the water surface to prevent these floating objects from entering the interior of the treatment tank 102. While stably achieving wastewater treatment, it can also achieve the separation operation between the floating objects and the water body. The fishing mechanism 3 can automatically fish and collect the floating objects intercepted by the fixed interception rod 203, simplifying the collection process. It can be operated on the shore without going into the water. When the lifting seat 30 When the driving rod 301 is in the lowest use position, the linkage rod 202 is at the bottom of the wastewater body, that is, the fishing rod 2041 and the blocking rod 2042 are both at the bottom of the intercepted floating objects. When the floating objects need to be caught and collected, the lifting seat 303 only needs to be driven upward by the driving motor 301. When the driving motor 301 rotates, it can drive the driving rod 302 to rotate synchronously. When the driving rod 302 rotates, it can drive the lifting seat 303 to move up and down inside the fixed seat 201 through the rod body thread, so that the lifting seat 303 can realize the fishing and collection operation of the floating objects when it moves upward. The lifting seat 303 can automatically reset when it moves downward, and can drive the linkage rod 202 when it moves upward. The lifting seat 303 moves upward synchronously, and the follower block 204 is in a horizontal use state under the action of the reset top spring 3041, and the fishing rod 2041 is located on the water-facing side, so when the fishing rod 2041 follows the follower block 204 and the linkage rod 202 to move upward, the fishing rod 2041 with an upward tilt design can support the intercepted floating objects, and under the action of the blocking rod 2042, the supported floating objects will not fall. As the lifting seat 303 continues to move upward, the linkage block 304 will be blocked and resisted by the abutment protrusion 2011, so that the linkage block 304 cannot continue to move upward synchronously with the lifting seat 303. Thereafter, when the lifting seat 303 moves upward, the linkage block 304 will shrink toward the inside of the lifting seat 303 and compress the reset top spring 3011. 41, and in this process, the linkage rack 3042 can drive the linkage rod 202 to rotate through the linkage gear 2021, so that the follower block 204, the fishing rod 2041 and the blocking rod 2042 are turned upward by 180 degrees, thereby pouring the supported floating objects into the interior of the collecting chute 103 located on the back water side. Since the interior of the collecting chute 103 is inclined, these floating objects will automatically slide into the interior of the collecting box 104 for collection, which is convenient and flexible to use. After that, by controlling the lifting seat 303 to descend, under the action of the reset top spring 3041, the linkage rod 202 can automatically reverse and reset and follow the lifting seat 303 to move down to the bottom of the water body again, so as to prepare for the next collection and fishing of floating objects.
