Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a wastewater treatment device. Background Technology

[0002] Wastewater treatment in the mining industry is a key link in ensuring the green development of the mining industry. Wastewater contains heavy metals, suspended solids, and acid and alkali pollutants. Large particles need to be intercepted by screens, suspended solids need to be settled in sedimentation tanks, pH value needs to be adjusted by neutralization, heavy metals need to be removed by chemical precipitation and ion exchange, organic matter needs to be degraded by biological treatment, and finally disinfected to meet the standards for discharge or reuse.

[0003] A related technology (publication number CN218968883U) discloses a mining wastewater treatment device, including a device support plate, a primary filter tank fixedly installed at the top of the support plate, a treatment tank fixedly installed at the top of the support plate, symmetrically fixed installation grooves on the top of the inner side wall of the primary filter tank, a filter screen plate slidably installed in the installation groove, an inlet at the top of the primary filter tank, and a discharge tank connected to the treatment tank at the bottom of the support plate. Fixed installation strips are fixedly installed on the inner wall of the discharge tank, and fixed slide rails are symmetrically fixedly installed on the inner side wall of the discharge tank. A sliding filter plate is slidably installed between the fixed slide rails. This utility model, by setting a pumping mechanism, can avoid the impact of sand, mud, branches, and other debris in the wastewater on subsequent treatment. By setting a stirring mechanism and a chemical injection mechanism, and by driving the stirring blades with a drive motor, the wastewater and chemical solution are mixed more thoroughly.

[0004] In existing mining wastewater treatment processes, key processes such as flocculation and sedimentation separation are usually configured with independent modular equipment. This approach has the following systemic defects.

[0005] 1. Inefficient space utilization: Multiple independent modular devices need to be distributed, occupying a large area, and long-distance pipeline connections increase infrastructure costs;

[0006] 2. Rigid and fixed process: The series process cannot selectively activate the treatment units. For example, when only the sedimentation unit needs to be activated, the wastewater still needs to flow through the pre-flocculation equipment, resulting in ineffective energy consumption.

[0007] The above-mentioned model not only increases equipment investment and operating costs, but also restricts the adaptability of wastewater treatment systems under complex operating conditions. Utility Model Content

[0008] In existing mining wastewater treatment processes, key steps such as flocculation and sedimentation separation are typically handled by independent modular equipment. This approach suffers from low space efficiency and rigid process design, increasing equipment investment and operating costs, and limiting the adaptability of the wastewater treatment system under complex operating conditions. This invention provides a wastewater treatment device that integrates flocculation, sedimentation, and solid-liquid separation into a single system. This avoids the large footprint required for individual equipment installations, saves on infrastructure costs associated with long-distance pipeline connections, and achieves higher space utilization. The specific technical solution is as follows:

[0009] A wastewater treatment device includes a treatment tank. A first partition is installed horizontally inside the treatment tank, dividing the inner cavity of the treatment tank into a flocculation reaction chamber and a sedimentation separation reaction chamber. A first inclined plate is installed at the bottom of the inner cavity of the flocculation reaction chamber, tilted downwards from left to right. Multiple sets of flow guiding components are arranged on the upper surface of the first inclined plate, with adjacent sets of flow guiding components alternately tilted on the upper surface of the first inclined plate. A second inclined plate is installed at the bottom of the inner cavity of the sedimentation separation reaction chamber, tilted upwards from left to right. A separation component is provided in the inner cavity of the sedimentation separation reaction chamber. The separation component includes multiple sets of screens, which are equidistantly arranged along the upper surface of the second inclined plate. Each set of screens consists of a vertical portion and a horizontal portion, and the angle between the vertical portion and the horizontal portion is less than 90 degrees.

[0010] In the above technical solution, the height of the right edge of the second inclined plate is lower than the height of the right edge of the first inclined plate.

[0011] In the above technical solution, a second partition is installed on the first inclined plate, and a first through hole is opened on the second partition. The first through hole corresponds to the position of the flow guiding component on the first inclined plate.

[0012] In the above technical solution, the flow guiding component includes a straight flow guiding plate and an arc-shaped flow guiding plate, the arc-shaped flow guiding plate is configured to be arc-shaped, and the straight flow guiding plate is connected to the first partition or the processing box.

[0013] In the above technical solution, a groove is provided on the upper surface of the first partition plate, a second through hole is provided through the side wall of the first partition plate from front to back, and a connecting component is provided in the groove of the first partition plate.

[0014] The connecting component includes a first mounting block installed on the right side wall of the processing box. A cylinder is installed at the bottom end of the first mounting block. The output end of the cylinder extends upward from the first mounting block and is equipped with a connecting rod. A baffle is installed at the bottom end of the connecting rod. The baffle is slidably inserted into the cavity of the groove opened on the first partition. A third through hole is opened from front to back on the side wall of the baffle.

[0015] The third through hole corresponds to the position of the second through hole.

[0016] In the above technical solution, the separation component further includes two second mounting blocks fixedly installed on the upper surface of the processing box and the first partition plate. Support rods are respectively installed on the side walls of the two second mounting blocks, and positioning pins are threaded through the two second mounting blocks respectively. A handle is fixedly installed between the two support rods.

[0017] Multiple sets of the screens are respectively installed below the support rod.

[0018] In the above technical solution, multiple sets of screens are arranged sequentially along the horizontal direction. That is, the leftmost set of screens has the smallest aperture, and as they are arranged to the right, the aperture of the apertures on the subsequent sets of screens increases sequentially.

[0019] In the above technical solution, a controller is installed on the front side wall of the treatment tank, and a water inlet assembly and a water outlet assembly are provided on the rear side of the treatment tank.

[0020] In the above technical solution, the water inlet assembly includes two second support seats installed on the rear side wall of the treatment tank. A water inlet pipe is provided through the two second support seats. The water inlet pipe is T-shaped. A first solenoid valve is provided at the intersection of the T-shaped water inlet pipe. A first input pipe and a second input pipe are respectively connected to the left and right sides of the water inlet pipe. The free end of the first input pipe extends into the left side of the flocculation reaction chamber, and the free end of the second input pipe extends into the right side of the sedimentation separation reaction chamber.

[0021] In the above technical solution, the water outlet component includes two first support seats fixedly installed on the rear side wall of the treatment tank. A water outlet pipe is provided through the two first support seats. The water outlet pipe is T-shaped. A second solenoid valve is provided at the intersection of the T-shaped water outlet pipes. A second output pipe and a first output pipe are respectively connected to the left and right sides of the water outlet pipe. The free end of the second output pipe extends into the left side of the inner cavity of the sedimentation separation reaction chamber, and the free end of the first output pipe extends into the right side of the inner cavity of the flocculation reaction chamber.

[0022] The wastewater treatment device of this utility model has the following advantages compared with the prior art:

[0023] I. In existing mining wastewater treatment processes, key processes such as flocculation and sedimentation separation are usually configured with independent modular equipment. This approach suffers from low space efficiency and rigid process, which not only increases equipment investment and operating costs but also restricts the adaptability of the wastewater treatment system under complex operating conditions. This utility model provides an integrated system for flocculation and sedimentation separation in wastewater treatment, avoiding the problem of large floor space required by separate equipment and saving on infrastructure costs caused by long-distance pipeline connections, while achieving higher space utilization.

[0024] Second, in this utility model, wastewater flocculation can be carried out in the flocculation reaction chamber, and wastewater sedimentation and separation can be carried out in the sedimentation and separation reaction chamber. The two can be selectively connected in series and used sequentially, or connected in parallel and used individually in their respective chambers. Compared with the problem that the existing series process cannot selectively activate the treatment units, this utility model can selectively select the corresponding reaction mode for different wastewater treatment steps. It can meet the treatment method of wastewater undergoing flocculation and sedimentation and separation in sequence, or it can meet the treatment method of only performing wastewater sedimentation and separation reaction. The wastewater treatment equipment is more flexible and improves the adaptability of the wastewater treatment system under complex working conditions.

[0025] Third, in this utility model, by setting up the first mounting block, cylinder, connecting rod, baffle, third through hole and other components, the selective connection or closure of the inner cavity of the flocculation reaction chamber and the sedimentation separation reaction chamber can be achieved, that is, the purpose of integrated application or single application of flocculation and sedimentation separation can be carried out as needed.

[0026] IV. When treating wastewater by flocculation reaction in the flocculation reaction chamber, this utility model is equipped with multi-level flow guiding components. When multi-level flow guiding components are set in the flocculation tank, the wastewater will generate centrifugal force when it flows along the flow guiding components, thereby forming a vortex and then forming multiple independent vortex regions. The vortex regions cause the wastewater to continuously change direction and speed, providing good coagulation conditions for the full collision and reaction of flocculant and wastewater.

[0027] V. In this utility model, multiple sets of flow guiding components are arranged alternately and staggeredly, so that the wastewater flow continuously changes direction and speed when passing through the flow guiding components, forming a complex swirling area, thereby increasing the turbulence of the wastewater flow, increasing the collision probability of flocculants, and further ensuring the full reaction between flocculant and wastewater flow.

[0028] VI. In this utility model, multiple sets of screens are set in the sedimentation and separation reaction chamber. Using multiple sets of screens, wastewater is treated by sedimentation and separation in a targeted, step-by-step manner. As the wastewater passes through these stages in sequence, suspended solids and impurities of different particle sizes can be gradually intercepted and precipitated at different stages. For example, larger particles are separated in the earlier stages, and smaller particles are further removed in the later stages. This is more efficient than single-screen filtration and can significantly improve the sedimentation and separation speed and processing capacity. In addition, single screens have limited filtration precision and are difficult to effectively remove fine particles and colloidal substances. However, this application can use multi-stage screens with different pore sizes according to the characteristics of different stages to treat wastewater more finely, resulting in better water quality and easier compliance with discharge standards.

[0029] VII. In response to the problem that traditional horizontal screens are placed horizontally, and that once a part of the screen becomes clogged, the water passage area is reduced and the separation efficiency is decreased, this utility model uses a multi-level screen set in the sedimentation separation reaction chamber, and the bottom bend of the screen is set with an acute angle. As the sediment slowly settles, the sediment gradually accumulates automatically at the acute bend of the screen, without blocking other filtration paths. The overall water passage capacity of the screen is minimally affected, and a high separation efficiency can be continuously maintained, allowing wastewater to pass through the screen more smoothly for sedimentation and separation.

[0030] In summary, this utility model has significant advantages in mining wastewater treatment. Through an integrated flocculation and sedimentation separation system, it saves space and infrastructure costs, and improves space utilization. It allows for selective activation of treatment units, adapting to complex operating conditions. The system achieves integrated or individual application of flocculation and sedimentation separation through component coordination. Multi-layered flow guiding components in the flocculation tank create a swirling zone, promoting full reaction between the flocculant and wastewater. Multiple sets of flow guiding components are arranged in an alternating, staggered manner to increase the probability of collision between flocculent particles. During sedimentation separation, multi-stage screens process wastewater step-by-step, improving efficiency and water quality. The sharp-angled bend at the bottom of the screens prevents clogging by sediment, ensuring high separation efficiency. Attached Figure Description

[0037] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0038] See Figures 1 to 5 As shown, a wastewater treatment device includes a treatment tank 1. A first partition 2 is installed horizontally inside the treatment tank 1, dividing the inner cavity of the treatment tank 1 into a flocculation reaction chamber 3 and a sedimentation separation reaction chamber 4. This integrates flocculation and sedimentation separation into a single system for wastewater treatment, avoiding the large footprint caused by separate installations and saving on infrastructure costs due to long-distance pipeline connections. This results in higher space utilization. A first inclined plate 5 is installed at the bottom of the inner cavity of the flocculation reaction chamber 3, tilted downwards from left to right. Multiple sets of flow guiding components are arranged on the upper surface of the first inclined plate 5, with adjacent sets of flow guiding components alternately tilted on the upper surface of the first inclined plate 5. The sedimentation separation reaction chamber 4... A second inclined plate 32 is installed at the bottom of the inner cavity, tilting upwards from left to right. The inner cavity of the sedimentation separation reaction chamber 4 is equipped with a separation component, which includes multiple sets of screens 21. The multiple sets of screens 21 are equidistantly arranged along the upper surface of the second inclined plate 32. Each set of screens 21 consists of a vertical part and a horizontal part, and the angle between the vertical part and the horizontal part is less than 90 degrees. That is, the bend at the bottom of the screen 21 is set as an acute angle. As the sediment slowly settles, the sediment gradually accumulates automatically at the acute bend of the screen 21, without blocking other filtration paths. The overall water flow capacity of the screen 21 is minimally affected, and a high separation efficiency can be continuously maintained, allowing wastewater to pass through the screen 21 more smoothly for sedimentation and separation.

[0039] When treating wastewater through flocculation reaction in flocculation reaction chamber 3, multiple layers of flow guiding components are installed in the flocculation tank. When the wastewater flows along the flow guiding components, centrifugal force is generated, thus forming a vortex. This forms multiple independent vortex zones, which cause the wastewater flow to continuously change direction and speed, providing good coagulation conditions for the full collision and reaction of flocculant and wastewater. In addition, multiple sets of flow guiding components are arranged alternately and staggered, causing the wastewater flow to continuously change direction and speed as it passes through the flow guiding components, forming complex vortex zones. This increases the turbulence of the wastewater flow, improves the collision probability of flocculant particles, and further ensures the full reaction of flocculant and wastewater flow.

[0040] By utilizing multiple sets of screens 21, wastewater is treated with targeted sedimentation and separation at different stages. As the wastewater passes through these stages, suspended solids and impurities of different particle sizes are gradually intercepted and precipitated at each stage. For example, larger particles are separated in the earlier stages, while smaller particles are further removed in subsequent stages. This method is more efficient than single-stage filtration with a single screen, significantly improving sedimentation and separation speed and throughput. Furthermore, single screens, due to their limited filtration precision, are unable to effectively remove fine particles and colloidal substances. This application, however, employs multi-stage screens 21 with different pore sizes based on the characteristics of each stage, enabling more refined wastewater treatment and resulting in better water quality that is more likely to meet discharge standards.

[0041] Main references Figure 2 As shown, the flow guiding assembly includes a straight flow guide plate 8 and an arc-shaped flow guide plate 9. The arc-shaped flow guide plate 9 is configured to be arc-shaped, and the straight flow guide plate 8 is connected to the first partition plate 2 or the processing box 1.

[0042] Specifically, the height of the right edge of the second inclined plate 32 is lower than the height of the right edge of the first inclined plate 5, thereby ensuring that when the flocculation reaction chamber 3 and the sedimentation separation reaction chamber 4 are connected, the mixture of flocculants and wastewater in the inner cavity of the flocculation reaction chamber 3 can smoothly enter the sedimentation separation reaction chamber 4 for subsequent sedimentation treatment.

[0043] Main references Figure 1 As shown, a second partition 6 is installed on the first inclined plate 5, and a first through hole 7 is provided on the second partition 6. The first through hole 7 corresponds to the position of the flow guiding component on the first inclined plate 5. The mixture after flocculation reaction in the flocculation reaction chamber 3 can enter the right end of the first inclined plate 5 through the first through hole 7, and enter the sedimentation separation reaction chamber 4 through the first partition 2 in the open state.

[0044] Main references Figure 1 and Figure 2As shown, a groove is formed on the upper surface of the first partition 2, and a second through hole 11 is formed through the side wall of the first partition 2 from front to back. A connecting component is provided at the groove of the first partition 2. The connecting component includes a first mounting block 12 installed on the right side wall of the processing box 1. A cylinder 13 is installed at the bottom end of the first mounting block 12. The output end of the cylinder 13 extends upward out of the first mounting block 12 and is equipped with a connecting rod 14. A baffle 15 is installed at the bottom end of the connecting rod 14. The baffle 15 is slidably inserted into the inner cavity of the groove formed on the first partition 2. A third through hole 16 is formed on the side wall of the baffle 15 from front to back. The third through hole 16 corresponds to the position of the second through hole 11.

[0045] When continuous treatment of wastewater flocculation and sedimentation separation is required, the cylinder 13 can drive the connecting rod 14 and the baffle 15 to move vertically, thereby achieving the corresponding or misaligned positions of the third through hole 16 and the second through hole 11. When the third through hole 16 and the second through hole 11 are aligned, the inner cavities of the flocculation reaction chamber 3 and the sedimentation separation reaction chamber 4 can be connected. When the third through hole 16 and the second through hole 11 are misaligned, the inner cavities of the flocculation reaction chamber 3 and the sedimentation separation reaction chamber 4 can be separated. That is, by setting the first mounting block 12, cylinder 13, connecting rod 14, baffle 15, third through hole 16 and other components, selective connection or closure of the inner cavities of the flocculation reaction chamber 3 and the sedimentation separation reaction chamber 4 can be achieved, so as to achieve the purpose of integrated application or single application of flocculation and sedimentation separation as needed.

[0046] Wastewater flocculation can be performed in flocculation reaction chamber 3, and wastewater sedimentation can be performed in sedimentation separation reaction chamber 4. The two can be selectively connected in series and used sequentially, or connected in parallel and used individually in their respective chambers. Compared with the problem that the existing series process cannot selectively activate the treatment units, this utility model can selectively select the corresponding reaction mode for different wastewater treatment steps. It can meet the treatment method of wastewater undergoing flocculation and sedimentation separation in sequence, or it can meet the treatment method of only performing wastewater sedimentation separation reaction. The wastewater treatment equipment is more flexible and improves the adaptability of the wastewater treatment system under complex working conditions.

[0047] Main references Figure 2 , Figure 3 and Figure 5 As shown, the separation assembly also includes two second mounting blocks 17 fixedly installed on the upper surfaces of the processing box 1 and the first partition 2. Support rods 18 are respectively installed on the side walls of the two second mounting blocks 17. Positioning pins 19 are threaded through the two second mounting blocks 17 respectively. A handle 20 is fixedly installed between the two support rods 18. Multiple sets of screens 21 are respectively installed below the support rods 18.

[0048] By rotating the positioning pin 19 out of the corresponding position of the second mounting block 17, the second mounting block 17 is separated from the top of the sedimentation separation reaction chamber 4. That is, by lifting the handle 20, multiple sets of screens 21 can be lifted upwards away from the inner cavity of the sedimentation separation reaction chamber 4 to clean the precipitate on the screens 21. After cleaning, refer to the above steps to install the screens 21, thus realizing the daily cleaning and maintenance of this application.

[0049] For details, please refer to the main references. Figure 5 As shown, multiple sets of screens 21 are arranged sequentially in the horizontal direction. The leftmost set of screens 21 has the smallest aperture, and the aperture of the subsequent sets of screens 21 increases sequentially to the right. This ensures that the rightmost screen 21 can preferentially precipitate larger particles, while the leftmost screen 21 precipitates smaller particles last. This ensures that the precipitates are separated step by step under the action of the multi-level screens 21, resulting in better precipitation separation. The mixture of flocculants and wastewater enters the connected second and third through holes 11 and 16 through the first through hole 7 and flows to the left along the inclined second inclined plate 32. Under the action of the multi-level screens 21, the precipitates after the flocculation reaction are separated. The precipitates are separated layer by layer under the obstruction of the multi-level screens 21. The precipitates accumulate at the acute angles of the screens 21, and the water separated from the precipitates flows to the left through the screens 21.

[0050] Main references Figure 2 and Figure 3As shown, a controller 22 is installed on the front wall of the treatment tank 1, and an inlet assembly and an outlet assembly are arranged on the rear side of the treatment tank 1. The inlet assembly includes two second support bases 33 installed on the rear wall of the treatment tank 1, and an inlet pipe 23 is installed through the two second support bases 33. The inlet pipe 23 is T-shaped, and a first solenoid valve 24 is arranged at the intersection of the T-shaped inlet pipe 23. A first input pipe 25 and a second input pipe 26 are respectively connected to the left and right sides of the inlet pipe 23. The free end of the first input pipe 25 extends into the left side of the inner cavity of the flocculation reaction chamber 3, and the free end of the second input pipe 26 extends into the right side of the inner cavity of the sedimentation separation reaction chamber 4. When the equipment performs flocculation and sedimentation separation of wastewater in the overall process, the controller 22 controls the first solenoid valve 24 to rotate to the state that connects the inlet pipe 23 and the first input pipe 25. At this time, the wastewater first enters the inner cavity of the flocculation reaction chamber 3 through the first input pipe 25. The flocculant in the inner cavity of the flocculant inlet tank 10 is opened and the flocculant is released downwards, following the flow of the wastewater entering through the first input pipe 25. Under the guidance of the multi-level straight guide plate 8 and arc guide plate 9 arranged from left to right in the flocculation reaction chamber 3, a multi-level swirling zone is formed, which promotes the flocculant and wastewater to fully react and form a flocculated mixture. The mixture enters the second through hole 11 and the third through hole 16 in a connected state through the first through hole 7, and flows to the left along the inclined second inclined plate 32. Under the action of the screens 21 arranged layer by layer, the precipitate after the flocculation reaction is separated. The precipitate is separated layer by layer under the obstruction of the multi-level screens 21, and the precipitate accumulates at the acute angle of the screens 21.

[0051] The effluent assembly includes two first support seats 27 fixedly installed on the rear side wall of the treatment tank 1. An effluent pipe 28 is installed through the two first support seats 27. The effluent pipe 28 is T-shaped. A second solenoid valve 29 is installed at the T-shaped intersection of the effluent pipe 28. A second output pipe 31 and a first output pipe 30 are respectively connected to the left and right sides of the effluent pipe 28. The free end of the second output pipe 31 extends into the left side of the inner cavity of the sedimentation separation reaction chamber 4, and the free end of the first output pipe 30 extends into the right side of the inner cavity of the flocculation reaction chamber 3. The controller 22 controls the second solenoid valve 29 and causes the second solenoid valve 29 to rotate to achieve the state of connecting the second output pipe 31. The sediment accumulates at the acute angle of the screen 21. The water separated from the sediment flows to the left through the screen 21 and is discharged into the effluent pipe 28 through the second output pipe 31. Thus, the wastewater is treated by flocculation and sedimentation separation and discharged as water that meets the requirements.

[0052] It is worth noting that the cylinder 13 used in this application is a commonly used self-locking cylinder on the market, whose output end can stop at any position and lock; the controller 22 is a commonly used controller model on the market, which is a digital computing electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input and output. In this application, the controller 22 can control the relevant components to rotate the corresponding valves in the corresponding directions, as well as perform other commands. Specifically, the controller 22 is electrically connected to the cylinder 13, the first solenoid valve 24, and the second solenoid valve 29, respectively. The controller 22 is capable of controlling the aforementioned components to perform corresponding commands, and it only needs to meet the usage requirements; its model is not limited or described in detail here. The first solenoid valve 24 and the second solenoid valve 29 are both commonly used solenoid valves on the market. They are electromagnetically controlled industrial devices and are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic systems. They are used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. They only need to meet the usage requirements for controlling the flow direction of wastewater in this application; their model is not detailed or limited here. The outlet pipe 28 is connected to an external water pump. The existing water pump can discharge the water or flocculent in the outlet pipe 28 to the next process. This is prior art and is not detailed or limited here.

[0053] The working principle of the wastewater treatment device in this embodiment is as follows:

[0054] When the equipment processes wastewater through flocculation and sedimentation, the controller 22 controls the first solenoid valve 24 to rotate, connecting the inlet pipe 23 and the first input pipe 25, and causes the second solenoid valve 29 to rotate, connecting the second output pipe 31. At this time, the wastewater first enters the flocculation reaction chamber 3 through the first input pipe 25. The flocculant inlet tank 10 opens, and the downward-flowing flocculant follows the wastewater entering through the first input pipe 25. Guided by the multi-level straight guide plates 8 and arc-shaped guide plates 9 arranged from left to right within the flocculation reaction chamber 3, multi-level swirling zones are formed, promoting flocculation. The agent reacts fully with the wastewater to form a flocculated mixture. The mixture enters the connected second through hole 11 and third through hole 16 through the first through hole 7 and flows to the left along the inclined second inclined plate 32. Under the action of the layered screens 21, the precipitate after the flocculation reaction is separated. The precipitate is separated layer by layer by the multi-layered screens 21. The precipitate accumulates at the acute angle of the screen 21. The water separated from the precipitate flows to the left through the screen 21 and is discharged to the outlet pipe 28 through the second outlet pipe 31. Thus, the wastewater is treated by flocculation and sedimentation separation and discharged as water that meets the requirements.

[0055] When wastewater needs to be treated separately by flocculation, the cylinder 13 drives the connecting rod 14 and the third through hole 16 to move, so that the third through hole 16 and the second through hole 11 are misaligned, that is, the inner cavity of the flocculation reaction chamber 3 and the sedimentation separation reaction chamber 4 are separated. The controller 22 controls the inlet pipe 23 and the first input pipe 25 to form a communication state, and controls the outlet pipe 28 and the first output pipe 30 to form a communication state. According to the above principle, the flocculant in the flocculant dosing tank 10 reacts fully with the wastewater entering the first input pipe 25. Under the action of multiple sets of straight guide plates 8 and arc guide plates 9 and the first inclined plate 5, the flocculation reaction is fully carried out, and the flocculent is discharged to the outside through the outlet pipe 28.

[0056] When wastewater needs to be treated by separate sedimentation, the cylinder 13 drives the connecting rod 14 and the third through hole 16 to move, so that the third through hole 16 and the second through hole 11 are misaligned, that is, the inner cavity of the flocculation reaction chamber 3 and the sedimentation separation reaction chamber 4 are separated. The controller 22 controls the inlet pipe 23 to be connected to the second input pipe 26 and controls the second output pipe 31 to be connected to the outlet pipe 28. According to the above principle, the wastewater entering through the inlet pipe 23 directly enters the sedimentation separation reaction chamber 4 through the second input pipe 26. Under the action of the multi-level screen 21 and the inclined second inclined plate 32, the wastewater can be directly treated by sedimentation. The sediment is precipitated at the multi-level screen 21, and the water enters the outlet pipe 28 through the second output pipe 31 and is discharged to the outside by the water pump connected to the outside.

[0057] This invention offers significant advantages in mining wastewater treatment. Through an integrated flocculation and sedimentation separation system, it saves space and infrastructure costs, improving space utilization. It allows for selective activation of treatment units, adapting to complex operating conditions. The system enables integrated or individual application of flocculation and sedimentation separation through component coordination. Multi-layered flow guiding components in the flocculation tank create a swirling zone, promoting full reaction between the flocculant and wastewater. Alternating staggered arrangement of multiple flow guiding components increases the probability of collision between flocculent particles. During sedimentation separation, multi-level screens 21 process wastewater step-by-step, improving efficiency and water quality. The sharp-angled bend at the bottom of the screens 21 prevents clogging by sediment, ensuring high separation efficiency.
