Description

Technical Field

[0001] This invention relates to the technical field of mining sludge and wastewater treatment systems, specifically to a stepwise sludge and wastewater treatment system and process based on lead-zinc mining. Background Technology

[0002] Lead-zinc mining generates a significant amount of wastewater containing sludge. Therefore, it is necessary to use sludge and wastewater distribution treatment equipment to treat the generated sludge and wastewater. First, centrifugation or filtration technology is used to separate the sludge from the wastewater. Then, the separated sludge is treated. Subsequently, the wastewater undergoes pre-treatment and post-treatment. The sludge and wastewater from the mine contains a large number of metal ions. In the pre-treatment, sulfidation equipment is used for sulfidation. The sulfidation method involves adding a sulfidating agent to the mine wastewater and allowing it to react fully. The large number of metal ions present in the mine wastewater are removed through precipitation and filtration, thereby obtaining relatively clean mine wastewater.

[0003] However, the sulfidation process generates a large amount of hydrogen sulfide waste gas, which can easily pollute the environment if it is not effectively adsorbed.

[0004] Therefore, it is necessary to provide a stepwise sludge and wastewater treatment system and process based on lead-zinc mining to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see Figures 1 to 18The present invention provides a technical solution: a sludge and wastewater step-by-step treatment system based on lead-zinc mining, including a sludge centrifuge 100, a sludge treatment device 200, a wastewater pretreatment device 300, and a wastewater posttreatment device 400. The wastewater pretreatment device 300 includes a treatment tank 1, in which a mixing tank 101, a sedimentation tank 102, and an aeration tank 103 are formed in sequence. Above the treatment tank 1, a gas collection component 2 is provided for drawing hydrogen sulfide gas generated by sulfiding wastewater, filtering it, and finally introducing the clean gas into the aeration tank 103 to aerate the wastewater.

[0046] During operation, a sludge centrifuge 100 is used to separate sludge from the wastewater. Then, a sludge treatment device 200 is used to treat the sludge, removing heavy metals and other substances to facilitate sludge backfilling. The wastewater is then treated with sulfidation in a treatment tank 1. Sulfidating agents are mixed in a mixing tank 101, and the mixed wastewater enters a sedimentation tank 102 for sedimentation. The clarified liquid at the top enters an aeration tank 103 for aeration. The hydrogen sulfide gas generated during this process is collected and filtered by a gas collection component 2. The filtered gas is then introduced into the aeration tank 103 to aerate the clarified wastewater, accelerating the separation and overflow of hydrogen sulfide. The treated wastewater then enters a sludge post-treatment device for further treatment until it can be safely discharged.

[0047] The mixed wastewater in the mixing tank 101 enters the sedimentation tank 102 and the clarified liquid in the sedimentation tank 102 enters the aeration tank 103, both of which are pumped by a water pump (not shown in the figure). This is the existing technology of the existing wastewater treatment tank 1, so it will not be described in detail here.

[0048] The gas collection assembly 2 includes a gas collection hood 21, which is fixed above the treatment tank 1. A first conduit 22 is fixed to the upper end of the gas collection hood 21. An air pump 23 is fixed to the outer wall of the treatment tank 1. A second conduit 24 is fixed to the air inlet end of the air pump 23. A sandwich plate 25 is fixed to the close ends of the first conduit 22 and the second conduit 24. A feeding roller 26 is rotatably mounted between the two sandwich plates 25. A first rotating shaft 262 is fixed to the middle of the feeding roller 26. The two ends of the first rotating shaft 262 are rotatably connected to the two sandwich plates 25 through bearings, and the lower end of the first rotating shaft 262 passes through the lower sandwich plate 25 and is rotatably connected to the outer wall of the gas collection hood 21 through a bearing. Four adsorption grooves 261 are opened at equal angles on the feeding roller 26. A storage container is also fixed to the outer wall of the gas collection hood 21. The discharge end of the storage bin 27 is fixed to a sandwich plate 25 at the upper end, and the lower opening of the storage bin 27 penetrates the sandwich plate 25 at the upper end. A discharge hopper 28 is fixed on the sandwich plate 25 at the lower end. The discharge hopper 28 is shaped like a cone with a large opening at the upper end and a small opening at the lower end. The discharge hopper 28 is offset from the second conduit 24 and the storage bin 27. A third conduit 29 is fixed to the air outlet end of the air pump 23. The air outlet end of the third conduit 29 is fixed to the outer wall of the treatment tank 1 and extends through the side wall of the treatment tank 1 to the inner side of the aeration tank 103. An air distributor 210 is fixed to the inner side of the aeration tank 103. The air outlet end of the third conduit 29 is connected to the air inlet end of the air distributor 210. An automatic rotating component 211 for driving the feeding roller 26 to rotate is fixed on the outer wall of the air collection hood 21.

[0049] During water treatment, the air pump 23 is turned on simultaneously, which draws in the hydrogen sulfide gas generated at the gas collection hood 21. The gas, mixed with air, enters the first conduit 22 and then passes through an adsorption tank 261, which is directly opposite the first conduit 22 and the second conduit 24. The adsorption tank 261 is filled with activated carbon, which adsorbs the hydrogen sulfide. The clean air then enters the second conduit 24 through the adsorption tank 261 and is then introduced into the air distributor 210, which evenly distributes the air into the aeration tank 103. A large number of bubbles rise in the water, creating disturbance and vibration. This vibration accelerates the release of hydrogen sulfide gas from the water, eliminating the need for a separate vibration device and saving on equipment production and operation and maintenance costs.

[0050] The automatic rotation component 211 includes a motor 2111. The motor 2111 is fixed on the outer wall of the gas collection hood 21. The motor 2111 is a worm gear reducer motor 2111. The output end of the motor 2111 is fixed with a second rotating shaft 2112. The second rotating shaft 2112 is rotatably connected to the gas collection hood 21 through a bearing. The upper end of the second rotating shaft 2112 is fixed with a drive wheel 2113. The lower end of the first rotating shaft 262 is fixed with a grooved wheel 2114. The drive wheel 2113 cooperates with the grooved wheel 2114. The outer wall of the second rotating shaft 2112 is also fixed with a disturbance component 2115 for disturbing the activated carbon inside the storage bin 27.

[0051] When the activated carbon in the adsorption tank 261, which is directly opposite the first conduit 22 and the second conduit 24, reaches its time limit, the drive motor 2111 rotates, causing the drive wheel 2113 to rotate one revolution, thereby causing the groove wheel 2114 to rotate 90 degrees, which in turn causes the feeding roller 26 to rotate. This rotates the adsorption tank 261, which is loaded with effective activated carbon, to be directly opposite the first conduit 22 and the second conduit 24. Then, the activated carbon in the adsorption tank 261 can be used to adsorb hydrogen sulfide gas. The ineffective activated carbon rotates to the position aligned with the discharge hopper 28. When it reaches this position, if the activated carbon is relatively loose, it will fall directly into the discharge hopper 28 and then overflow. In actual use, a receiving device can be placed below the discharge hopper 28 to collect the activated carbon. After it is full, it will be processed uniformly.

[0052] Before rotation, the adsorption tank 261, which was originally located at the discharge hopper 28, rotates to be aligned with the storage bin 27, and the activated carbon inside the storage bin 27 automatically falls into the adsorption tank 261.

[0053] The disturbance component 2115 includes a lifting bar 21151, which is slidably mounted on the outer wall of the storage bin 27. A vertical rod 21152 is fixed to the upper end of the lifting bar 21151, extending to the inner side of the storage bin 27. Disturbance bars 21153 are fixed at equal angles from top to bottom on the outer wall of the vertical rod 21152. A first spring 21154 is sleeved on the outer side of the lifting bar 21151, with one end of the first spring 21154 fixed to the outer wall of the lifting bar 21151 and the other end fixed to the outer side of the storage bin 27. The lower end of the second rotating shaft 2112 is fixed with a drive disk 21155, and the upper end of the drive disk 21155 forms a wave-shaped drive bar 21156. The bottom of the lifting bar 21151 cooperates with the outer wall of the drive bar 21156. The outer wall of the drive disk 21155 is also fixed with a push assembly 21157 for disturbing the activated carbon in the adsorption tank 261 that reaches the discharge hopper 28. The bottom of the lifting bar 21151 is fixed with a universal roller 8, and the universal roller 8 is in rolling connection with the outer wall of the drive bar 21156.

[0054] During the rotation of the drive wheel 2113, the drive disc 21155 is driven to rotate synchronously, thereby causing the drive bar 21156 to rotate. The wave-shaped design of the drive bar 21156 allows it to work with the first spring 21154 to make the lifting bar 21151 continuously rise and fall and slide back and forth, thereby causing the disturbance bar 21153 to disturb the clumped activated carbon, making the clumped activated carbon loose and facilitating material feeding.

[0055] The push assembly 21157 includes a top cone 211571, which is slidably connected to the side wall of the discharge hopper 28. The top of the top cone 211571 is flush with the bottom of the feeding roller 26. A push bar 211572 is slidably connected to the outer wall of the discharge hopper 28. A drive groove 211573 is provided on the push bar 211572. A drive column 211574 is fixed to the bottom of the top cone 211571, and the end of the drive column 211574 is inserted into the drive groove 211573. On the inner side, a second spring 211575 is fixed on the outer wall of the push bar 211572. The end of the second spring 211575 away from the push bar 211572 is fixed to the outer wall of the discharge hopper 28. The end of the push bar 211572 away from the drive groove 211573 abuts against the outer wall of the drive disk 21155. A protrusion 211576 is also fixed on the outer wall of the drive disk 21155. The two ends of the protrusion 211576 smoothly transition with the outer wall of the drive disk 21155.

[0056] During the rotation of motor 2111 to agitate the activated carbon in storage bin 27 and drive the feeding roller 26 to rotate, protrusion 211576 rotates together with drive disc 21155. After drive wheel 2113 rotates and meshes with grooved wheel 2114, and then pushes grooved wheel 2114 to rotate 90 degrees and separates from grooved wheel 2114, protrusion 211576 just rotates to the position of contacting the outer wall of push bar 211572. Then drive disc 21155 continues to rotate and reset. During this process, feeding roller 26 does not rotate. However, if activated carbon in an adsorption tank 261 opposite discharge hopper 28 becomes caked, protrusion 211576 will be affected by subsequent rotation of drive disc 2115. 5. During the continued rotation, the push bar 211572 can be pushed to slide, and the drive column 211574 and the top cone 211571 are driven to slide upward through the drive groove 211573, so that the upper end of the top cone 211571 is inserted into the inner side of the adsorption tank 261 to dissipate the activated carbon, making it easy for it to fall smoothly. Then the drive disc 21155 continues to rotate, and finally completes one rotation and resets. The protrusion 211576 is also reset. Under the action of the rebound force of the second spring 211575, the push bar 211572 is pulled to reset, so that the top cone 211571 moves downward and resets. When the feeding roller 26 is driven to rotate in the future, it will not hinder its movement.

[0057] Example 2

[0058] This invention also provides a process for a stepwise sludge and wastewater treatment system based on lead-zinc mining, which is the process of the aforementioned distributed sludge and wastewater treatment system based on lead-zinc mining. The specific steps are as follows:

[0059] S1. First, the sludge in the mine wastewater is separated by the sludge centrifuge 100, and then the separated sludge is fed into the sludge treatment equipment 200 for treatment.

[0060] S2. The separated wastewater is treated sequentially by wastewater pretreatment equipment 300 and wastewater posttreatment equipment 400 until it meets the discharge standards.

[0061] This application can effectively adsorb and treat hydrogen sulfide gas generated during the sulfidation treatment of mine wastewater, preventing it from overflowing and impacting the environment. In addition, it can accelerate the overflow of hydrogen sulfide gas in the wastewater while treating and adsorbing it. The gas collection component 2 can also automatically replace activated carbon during use, saving manual operation steps and making it convenient to use. During the automatic replacement process, it can also simultaneously overcome the problem of activated carbon caking.
