Description

A wastewater treatment device for municipal solid waste Technical Field

[0001] This invention relates to the technical field of environmental protection equipment, and in particular to a device for treating residual wastewater from domestic waste. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of urban domestic waste generated is increasing day by day. This waste contains a large amount of organic matter and water, especially in kitchen waste. When this waste is collected, transported and processed, a certain amount of wastewater is generated. This wastewater usually contains high concentrations of organic matter, suspended solids, grease and other harmful chemicals, which pose a serious threat to the environment. If it is discharged directly without proper treatment, it will not only pollute surface water and groundwater, but may also affect soil quality and even endanger human health.

[0003] As an effective solid-liquid separation method, air flotation technology has been widely used in wastewater treatment in recent years. This technology utilizes the collision and adhesion between microbubbles and suspended particles in wastewater to bring these particles to the water surface to form scum, which is then removed by a scum scraper or other means, thereby achieving the purpose of purifying water quality.

[0004] In traditional air flotation machines, to improve the effect of air flotation treatment of impurities in wastewater, a large number of aeration valves need to be arranged at the bottom of the air flotation tank along the water flow direction. This generates a large number of bubbles in the wastewater to treat the impurities. However, this structure will significantly increase costs, and the bubbles have a short path to rise. As a result, a large number of bubbles cannot perform their function of adsorbing impurities and rise directly to the surface, leading to a significant waste of bubbles. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a wastewater treatment device for municipal solid waste, the specific technical solution of which is as follows:

[0006] According to a first aspect of the present invention, a wastewater treatment device for municipal solid waste is provided, comprising a wastewater treatment tower, an inlet pipe, an overflow pipe, a slag discharge channel, and a bubble discharge structure. The wastewater treatment tower is vertical, the inlet pipe is installed at the top of the wastewater treatment tower, the overflow pipe is installed at the top of the wastewater treatment tower, wastewater enters the wastewater treatment tower from the inlet pipe and flows downward, and then is discharged through the overflow pipe. The slag discharge channel is installed on the side wall of the wastewater treatment tower and communicates with the interior of the wastewater treatment tower. Multiple sets of flow guiding structures are provided on both the left and right sides of the wastewater treatment tower, and the multiple sets of flow guiding structures inside the wastewater treatment tower are arranged vertically. The positions of the flow guiding structures on the left and right sides of the wastewater treatment tower are staggered. The bubble discharge structure is installed at the bottom of the wastewater treatment tower and is used to discharge bubbles into the wastewater treatment tower.

[0007] The overflow pipe is used to limit the water level in the wastewater treatment tower. The slag discharge channel is higher than the water surface in the wastewater treatment tower. The flow guiding structure draws water from the wastewater treatment tower and transports it downward through the input end located on its upper side. Then, the flow guiding structure discharges the water back into the wastewater treatment tower through the output end located on its lower side. The combined use of multiple sets of flow guiding structures on the left and right sides of the wastewater treatment tower enables the water in the wastewater treatment tower to flow downward in an S-shape.

[0008] Furthermore, the flow guiding structure includes a vertical cylinder and two water guiding channels connected to the upper and lower sides of the vertical cylinder. Both water guiding channels are connected to the wastewater treatment tower, and a spiral plate is rotatably installed inside the vertical cylinder.

[0009] Furthermore, the inlet pipe is fixed to the top of the wastewater treatment tower by a fixing frame, and a secondary pipe is fitted on the outside of the inlet pipe. A guide bucket is provided at the bottom of the secondary pipe, and the guide bucket and the secondary pipe are connected by a connecting plate.

[0010] The guide bucket is cone-shaped with its opening facing upwards.

[0011] Furthermore, the inlet pipe is located above the wastewater treatment tower, the secondary pipe passes through the wastewater treatment tower, and the secondary pipe and the inlet pipe are slidably connected to each other;

[0012] A vibration structure is installed between the secondary pipe and the inlet pipe, which provides vibration power to the secondary pipe and the guide bucket.

[0013] Furthermore, the secondary tube is equipped with multiple fan blades;

[0014] The wastewater treatment tower is equipped with a transmission structure, which is used to make the secondary pipe and the spiral plates in each set of flow guiding structures rotate synchronously. The transmission structure includes a transmission ring and two transmission wheels. The transmission ring is sleeved on the outer wall of the secondary pipe and is rotatably installed on the top of the wastewater treatment tower. The transmission ring and the two transmission wheels are connected by a transmission belt. Each transmission wheel is equipped with a transmission shaft. The two transmission shafts pass through multiple sets of flow guiding structures on the left and right sides of the wastewater treatment tower, and the transmission shafts are fixedly connected to the spiral plates in the flow guiding structures.

[0015] The outer wall of the secondary pipe has multiple sliding grooves, which are arranged vertically and are distributed in a ring around the outer wall of the secondary pipe. The inner wall of the transmission ring has multiple sliding ribs, which are slidably installed in the sliding grooves. The transmission shaft passes through the air bubble removal structure and is rotated and connected to each other.

[0016] Furthermore, the vibration structure includes a wave groove formed on the outer wall of the water inlet pipe, the wave groove is annular around the outer wall of the water inlet pipe, and multiple guide columns are slidably arranged inside the wave groove, the guide columns are fixedly connected to the secondary pipe.

[0017] Furthermore, an arc-shaped plate is slidably disposed on the inner wall of the wastewater treatment tower, and a connecting ring is rotatably sleeved on the outer wall of the secondary pipe. The connecting ring and the arc-shaped plate are fixedly connected by a connecting rod, and the connecting rod is submerged in the water inside the wastewater treatment tower.

[0018] Furthermore, the bubble removal structure includes multiple long pipes installed at the bottom of the inner wall of the wastewater treatment tower, each long pipe having multiple nozzles, and the multiple long pipes being connected by a multi-port pipe.

[0019] The beneficial effects of this invention are as follows:

[0020] By designing the wastewater to flow vertically in an S-shape within the wastewater treatment tower, the wastewater can easily pass through a bubble curtain formed by floating bubbles discharged from the bubble removal structure multiple times in the horizontal direction. This facilitates multiple convergence-type flotation effects between the wastewater and bubbles, increasing the contact time between wastewater and bubbles, improving the adsorption efficiency of suspended impurities by the bubbles, and reducing bubble waste. By setting staggered guide structures at different heights of the flotation unit, the wastewater is transported laterally, allowing it to pass through the bubble curtain multiple times within the wastewater treatment tower, enhancing the treatment capacity of the flotation unit. The S-shaped flow path design and the overall vertical flow trajectory of the wastewater within the wastewater treatment tower make the entire system more compact, reducing the footprint and making it suitable for the space constraints of wastewater treatment plants. Furthermore, its simple structure and convenient operation make it easy to operate. In summary, this technical solution, by improving the internal structure and water flow path of the flotation unit, increases bubble utilization, extends the contact time between bubbles and wastewater, simplifies the equipment, and reduces operating costs, thus effectively solving the problems existing in traditional flotation units.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0033] As shown in Figures 1 to 6, a wastewater treatment device for municipal solid waste according to the present invention includes a wastewater treatment tower 1, an inlet pipe 2, an overflow pipe 3, a slag discharge channel 4, and a bubble discharge structure 6. The wastewater treatment tower 1 is vertical. The inlet pipe 2 is installed at the top of the wastewater treatment tower 1, and the overflow pipe 3 is installed at the top of the wastewater treatment tower 1. Wastewater enters the wastewater treatment tower 1 from the inlet pipe 2 and flows downward, and then is discharged through the overflow pipe 3. The slag discharge channel 4 is installed on the side wall of the wastewater treatment tower 1 and communicates with the interior of the wastewater treatment tower 1. Multiple sets of flow guiding structures 5 are provided on both the left and right sides of the wastewater treatment tower 1, and the multiple sets of flow guiding structures 5 inside the wastewater treatment tower 1 are arranged vertically. The positions of the flow guiding structures 5 on the left and right sides of the wastewater treatment tower 1 are staggered. The bubble discharge structure 6 is installed at the bottom of the wastewater treatment tower 1 and is used to discharge bubbles into the wastewater treatment tower 1.

[0034] The overflow pipe 3 is used to limit the water level in the wastewater treatment tower 1. The slag discharge channel 4 is higher than the water surface in the wastewater treatment tower 1. The flow guiding structure 5 draws in the water in the wastewater treatment tower 1 and transports it downward through the input end located on its upper side. Then, the flow guiding structure 5 discharges the water back into the wastewater treatment tower 1 through the output end located on its lower side. The combined use of multiple sets of flow guiding structures 5 on the left and right sides of the wastewater treatment tower 1 enables the water in the wastewater treatment tower 1 to flow downward in an S-shape.

[0035] In detail, the overflow pipe 3 helps to maintain a sufficient amount of water in the wastewater treatment tower 1, that is, the wastewater level in the wastewater treatment tower 1 is fixed, and the inlet pipe 2 can continuously supply water into the wastewater treatment tower 1. The wastewater in the wastewater treatment tower 1 flows downwards. The connection point between the sludge discharge channel 4 and the wastewater treatment tower 1 is higher than the water level in the wastewater treatment tower 1, thereby preventing wastewater from being discharged through the sludge discharge channel 4. The guide structure 5 is used to draw in the wastewater in the wastewater treatment tower 1 and transport it downwards, and then discharge it horizontally into the wastewater treatment tower 1. Since the guide structures 5 on the left and right sides of the wastewater treatment tower 1 are staggered, the water discharged from the guide structure 5 on one side of the wastewater treatment tower 1 can enter the guide structure 5 on the other side of the wastewater treatment tower 1, thereby realizing the treatment of wastewater in the wastewater treatment tower. The lateral flow within the wastewater treatment tower 1, through the coordinated use of multiple sets of guiding structures 5 on the left and right sides of the tower, allows the wastewater to pass through these structures sequentially and be transported downwards. At this time, the wastewater flows in an S-shaped manner within the tower. The bubble degassing structure 6 can supply air bubbles into the wastewater within the tower, and these air bubbles will form a bubble curtain that floats upwards. When the wastewater flows laterally and passes through the bubble curtain, the air bubbles will perform a flotation treatment on the wastewater. That is, impurities in the wastewater will be adsorbed by the air bubbles and float upwards with the help of the air bubbles. Because the wastewater flows in an S-shaped manner under the guidance of multiple sets of guiding structures 5, it will repeatedly pass through the bubble curtain located in the middle of the tower while flowing downwards, thus performing multiple and repeated flotation operations on the wastewater through the air bubbles.

[0036] Based on the above embodiments, since the bubbles repeatedly perform flotation treatment on the horizontally flowing wastewater when they rise, it is convenient for the bubbles and wastewater to meet multiple times, so as to realize the continuous adsorption of impurities in the wastewater by the bubbles and make full use of the bubbles. Furthermore, since the water flow in the wastewater treatment tower 1 is vertical, the contact time between the bubbles and the wastewater can be extended, thus improving the flotation effect.

[0037] It should be noted that when the scum floats to the water surface, as the amount of scum gradually increases, the height of the scum rises. When it reaches the height of the scum discharge channel 4, the scum can be naturally discharged through the scum discharge channel 4.

[0038] By designing the wastewater to flow vertically in an S-shape within the wastewater treatment tower 1, the wastewater can easily pass through the bubble curtain formed by the floating bubbles discharged by the bubble removal structure 6 multiple times in the horizontal direction. This facilitates multiple convergence-type flotation effects between the wastewater and bubbles, increasing the contact time between wastewater and bubbles, improving the adsorption efficiency of suspended impurities by the bubbles, and reducing bubble waste. By setting staggered flow guide structures 5 at different heights of the flotation unit, the wastewater is transported laterally, allowing it to pass through the bubble curtain multiple times within the wastewater treatment tower 1, enhancing the treatment capacity of the flotation unit. The S-shaped flow path design and the overall vertical flow trajectory of the wastewater within the wastewater treatment tower 1 make the entire system more compact, reducing the footprint and making it suitable for the space constraints of wastewater treatment plants. Furthermore, its simple structure and convenient operation make it easy to implement. In summary, this technical solution, by improving the internal structure and water flow path of the flotation unit, increases bubble utilization, extends the contact time between bubbles and wastewater, simplifies the equipment, and reduces operating costs, thus effectively solving the problems existing in traditional flotation units.

[0039] Furthermore, the flow guiding structure 5 includes a vertical cylinder 7 and two water guiding channels 8 connected and installed on the upper and lower sides of the vertical cylinder 7. Both water guiding channels 8 are connected to the wastewater treatment tower 1. A spiral plate 9 is rotatably installed inside the vertical cylinder 7.

[0040] In detail, when the spiral plate 9 rotates, it can push the wastewater in the vertical cylinder 7 downward. At this time, the wastewater in the wastewater treatment tower 1 will naturally flow into the vertical cylinder 7 through the upper water guide channel 8, while the wastewater on the lower side of the vertical cylinder 7 will flow back into the wastewater treatment tower 1 through the lower water guide channel 8 of the vertical cylinder 7. This realizes the horizontal drainage of wastewater and facilitates the guidance of wastewater flow direction.

[0041] Furthermore, the inlet pipe 2 is fixed to the top of the wastewater treatment tower 1 by a fixing frame 25, and a secondary pipe 10 is fitted on the outside of the inlet pipe 2. A guide bucket 11 is provided at the bottom of the secondary pipe 10, and the guide bucket 11 and the secondary pipe 10 are connected by a connecting plate 12.

[0042] The guide bucket 11 is conical in shape, with its opening facing upwards.

[0043] In detail, the secondary pipe 10 is connected to the inlet pipe 2, and the guide bucket 11 is fixed to the secondary pipe 10 through the connecting plate 12. The guide bucket 11 is submerged in the wastewater in the wastewater treatment tower 1. The wastewater in the inlet pipe 2 can be introduced into the guide bucket 11 through the secondary pipe 10. The wastewater in the guide bucket 11 flows upward through the gap between the guide bucket 11 and the outer wall of the secondary pipe 10 and is discharged into the wastewater treatment tower 1, thereby realizing the wastewater supply. Furthermore, the design of the guide bucket 11 can prevent the scum in the wastewater from floating up and entering the secondary pipe 10, thus guiding and blocking the scum. The conical design of the guide bucket 11 can help the scum avoid the guide bucket 11 and float to the water surface.

[0044] Furthermore, the inlet pipe 2 is located above the wastewater treatment tower 1, the secondary pipe 10 passes through the wastewater treatment tower 1, and the secondary pipe 10 and the inlet pipe 2 are slidably connected to each other;

[0045] A vibration structure is provided between the secondary pipe 10 and the inlet pipe 2, which is used to provide vibration power for the secondary pipe 10 and the guide bucket 11.

[0046] In detail, by vibrating the secondary pipe 10 and the guide bucket 11, the scum in the wastewater and the scum on the water surface can be prevented from adsorbing onto the secondary pipe 10 and the guide bucket 11. When the secondary pipe 10 vibrates, it will form ripples on the water surface. The ripples can be used to drag the scum away from the secondary pipe 10, thereby preventing the scum from settling on the secondary pipe 10.

[0047] Furthermore, the secondary pipe 10 is provided with a plurality of fan blades 13;

[0048] The wastewater treatment tower 1 is equipped with a transmission structure, which is used to make the secondary pipe 10 and the spiral plate 9 in each group of flow guiding structures 5 rotate synchronously. The transmission structure includes a transmission ring 14 and two transmission wheels 15. The transmission ring 14 is sleeved on the outer wall of the secondary pipe 10 and is rotatably installed on the top of the wastewater treatment tower 1. The transmission ring 14 and the two transmission wheels 15 are connected by a transmission belt 16. Each transmission wheel 15 is equipped with a transmission shaft 17. The two transmission shafts 17 pass through multiple groups of flow guiding structures 5 on the left and right sides of the wastewater treatment tower 1, and the transmission shafts 17 are fixedly connected to the spiral plate 9 in the flow guiding structure 5.

[0049] The outer wall of the secondary tube 10 is provided with multiple sliding grooves, which are arranged in a vertical direction. The multiple sliding grooves are distributed in a ring around the outer wall of the secondary tube 10. The inner wall of the transmission ring 14 is provided with multiple sliding ribs, which are slidably installed in the sliding grooves. The transmission shaft 17 passes through the bubble removal structure 6 and is rotatably connected to each other.

[0050] In detail, when the wastewater flows through the secondary pipe 10, the wastewater will use multiple fan blades 13 inside the secondary pipe 10 to drive the secondary pipe 10 to rotate. At this time, the secondary pipe 10 will drive the transmission wheel 15 and the transmission belt 16 to rotate through the transmission ring 14, thereby driving the two transmission shafts 17 to rotate. The transmission shafts 17 then drive the spiral plate 9 inside the vertical cylinder 7 to rotate, which facilitates the provision of power to each set of flow guiding structures 5.

[0051] Based on the above embodiment, since the secondary pipe 10 and the guide bucket 11 rotate, the wastewater discharged from the uppermost guide structure 5 among the multiple guide structures 5 can flow laterally to the guide bucket 11, thereby using the water flow to achieve a comprehensive flushing effect on the outer wall of the guide bucket 11.

[0052] Since the secondary pipe 10 and the guide bucket 11 need to vibrate in the vertical direction, the transmission ring 14 and the secondary pipe 10 need to be connected by the structure of the sliding groove and the sliding ridge. When the secondary pipe 10 moves up and down, it slides relative to the transmission ring 14. When the secondary pipe 10 rotates, it rotates synchronously with the transmission ring 14.

[0053] Furthermore, the vibration structure includes a wave groove 18 formed on the outer wall of the water inlet pipe 2. The wave groove 18 is annular around the outer wall of the water inlet pipe 2. Multiple guide posts 19 are slidably arranged inside the wave groove 18. The guide posts 19 are fixedly connected to the secondary pipe 10.

[0054] In detail, since the water inlet pipe 2 is supported by the fixed frame 25, when the secondary pipe 10 rotates relative to the water inlet pipe 2, the secondary pipe 10 will drive the guide column 19 to slide in the wave groove 18. Due to the structural characteristics of the wave groove 18, the guide column 19 can reciprocate in the vertical direction, thereby driving the secondary pipe 10 and the guide bucket 11 to reciprocate in the vertical direction.

[0055] Furthermore, an arc-shaped plate 20 is slidably disposed on the inner wall of the wastewater treatment tower 1, and a connecting ring 21 is rotatably sleeved on the outer wall of the secondary pipe 10. The connecting ring 21 and the arc-shaped plate 20 are fixedly connected by a connecting rod 22, and the connecting rod 22 is submerged in the water inside the wastewater treatment tower 1.

[0056] In detail, when the secondary pipe 10 vibrates, it can drive the connecting ring 21, connecting rod 22 and bow plate 20 to vibrate synchronously. The bow plate 20 slides on the inner wall of the wastewater treatment tower 1. By utilizing the vibration of the bow plate 20 and the connecting ring 21, bidirectional ripples can be formed on the water surface. The ripples are used to make the scum on the water surface gather between the bow plate 20 and the connecting ring 21, thus preventing the scum from adsorbing and depositing on the inner wall of the wastewater treatment tower 1.

[0057] Based on the above embodiment, since the bow-shaped plate 20 is bow-shaped and its opening faces the slag discharge channel 4, when the bow-shaped plate 20 and the connecting ring 21 vibrate, the water waves will be transmitted towards the slag discharge channel 4. In this way, the ripples can be used to push the scum to the vicinity of the slag discharge channel 4, making it easier for the scum to be discharged. Since the connecting rod 22 is submerged in water, the vibration of the connecting rod 22 can be avoided from interfering with the water surface.

[0058] Furthermore, the bubble removal structure 6 includes multiple long pipes 23 installed at the bottom of the inner wall of the wastewater treatment tower 1, each long pipe 23 having multiple nozzles, and the multiple long pipes 23 being connected to each other through a multi-port pipe 24.

[0059] In detail, air can be pumped into the long pipe 23 through the multi-port pipe 24 and discharged into the water in the wastewater treatment tower 1 through the nozzle on the long pipe 23, thereby forming a large number of bubbles in the water. Of course, dissolved air or other methods can also be used to supply bubbles.

[0060] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
