Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and in particular relates to wastewater reuse treatment equipment for water environment management. Background Technology

[0002] The water environment refers to the spatial environment in which water is formed, distributed, and transformed in nature. It refers to the totality of various natural and related social factors surrounding human spaces and water bodies that can directly or indirectly affect human life and development, as well as the environment of relatively stable natural water bodies bounded by land. In many places, the water environment is severely polluted, causing pollution to the environment and a great waste of water resources. In order to protect the water environment, it is generally necessary to use sewage treatment devices to recycle and treat sewage.

[0003] Most existing wastewater treatment equipment consists of integrated wastewater treatment tanks, typically equipped with sedimentation, aerobic, and anaerobic zones. Wastewater is treated by passing it sequentially through these zones. However, this process requires the addition of activated sludge to decompose organic and inorganic matter in the wastewater using aerobic bacteria. To maintain the activity of these bacteria, air is introduced into the wastewater using aeration discs. However, existing tanks lack suitable sludge isolation devices, causing both the wastewater and activated sludge in the aerobic zone to churn during aeration. This results in turbidity in the aerobic zone. Furthermore, since oxygen is an oxidant, excessive contact with the activated sludge causes rapid aging, increasing oxygen consumption by aerobic bacteria and reducing the overall treatment efficiency.

[0004] Therefore, it is necessary to invent wastewater reuse treatment equipment for water environment management to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a wastewater reuse treatment device for water environment management, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater reuse treatment device for water environment management, comprising a cylindrical treatment tank, the treatment tank being placed horizontally, and an anaerobic zone, an aerobic zone, and a sedimentation zone being arranged sequentially along the axial direction of the treatment tank, the three being completely separated by two vertical partitions, the partitions being fixedly connected to the inner wall of the treatment tank, a first conveying pipe connecting the anaerobic zone and the aerobic zone, a first water pump being installed on the first conveying pipe, a second conveying pipe connecting the aerobic zone and the sedimentation zone, a second water pump being installed on the second conveying pipe, a first elastic packing and a second elastic packing being respectively arranged in the anaerobic zone and the aerobic zone, the second elastic packing having a partition on both sides. The treatment tank has a coaxial rotating wheel, with a first connecting rod fixedly connected to the second elastic packing. A drive assembly is installed on the rotating wheel near the anaerobic zone, and a fixed shaft is vertically fixedly connected to the center of the rotating wheel near the sedimentation zone. The fixed shaft is rotatably connected to the center of the partition plate near the sedimentation zone. A collection hood is provided on the bottom inner wall of the aerobic zone, and an isolation assembly is provided on the top of the collection hood. A one-way ring is rotatably sleeved on the outer periphery of the rotating wheel, and multiple second connecting rods are fixedly connected between the one-way ring and the isolation assembly. An aeration disc is installed inside the collection hood, and a sewage pipe is connected to the bottom of the collection hood. A sewage pump is installed on the sewage pipe. Through holes are provided at the top of the treatment tank at positions opposite to the anaerobic zone, aerobic zone, and sedimentation zone.

[0007] Furthermore, the drive assembly includes a drive shaft, which is vertically fixed to the center of the rotating wheel near the anaerobic zone. The free end of the drive shaft is vertically rotatably inserted into the center of the partition near the anaerobic zone. A drive motor is installed on the top of the treatment tank, located directly above the drive shaft. A connection hole is provided on the top of the treatment tank opposite to the output shaft of the drive motor. A transmission belt is connected between the output shaft of the drive motor and the drive shaft, and the transmission belt passes through the connection hole.

[0008] Furthermore, the isolation assembly includes an arc-shaped isolation plate that is completely fitted to the inner wall of the treatment tank and is fixedly connected to the second connecting rod. The width of the isolation plate matches the distance between the two partitions, and the arc length of the partition is greater than the length of the collection hood. Multiple elongated air inlet pipes are inserted side by side at the top of the isolation plate. The air inlet pipes are arc-shaped, and their arc is the same as that of the isolation plate. The top and bottom of the air inlet pipes are designed to be continuous, and a baffle strip matching its length is provided at the top opening of the air inlet pipe. There is a gap between the baffle strip and the top opening of the air inlet pipe, and the width of the baffle strip is greater than the width of the air inlet pipe. Multiple small connecting blocks are fixedly connected between the bottom of the baffle strip and the top of the air inlet pipe.

[0009] Furthermore, both the first and second elastic packings are composed of multiple sets of rectangular elastic packing individuals connected side by side, and the multiple elastic packing individuals on the second elastic packing are alternately distributed with multiple air intake pipes.

[0010] Furthermore, an arc-shaped baffle of the same size is fixedly connected to the rear edge of the isolation plate, and the baffle is completely in contact with the inner wall of the treatment tank. Multiple third connecting rods are fixedly connected between the baffle and the one-way ring.

[0011] Furthermore, multiple spiral protrusions are arranged in parallel on the inner side of the baffle, and the ends of the multiple spiral protrusions near the baffle are alternately distributed with multiple air intake pipes.

[0012] Furthermore, both sides of the baffle and the isolation plate protrude towards the axis of the processing tank. A scraper is provided on the side of the baffle away from the isolation plate. The two sides of the scraper are rotatably connected to the two protrusions on the sides of the baffle by torsion springs, and the scraper can fit against the inner wall of the processing tank under the action of the torsion springs.

[0013] Furthermore, the main cross-section of the baffle is rhomboid, and the diagonal side of the baffle is centered at the top opening of the air intake pipe.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. The present invention has an isolation component. During the sewage treatment process, the isolation plate can isolate the activated sludge, thereby preventing the aeration disc from being blocked by the activated sludge and ensuring the normal operation of the aeration disc. Moreover, the isolated activated sludge can also avoid contact with the air pumped into the aeration disc, extending the service life of the activated sludge. At the same time, it can also prevent the activated sludge from churning in the aerobic zone under the action of the gas pumped out by the aeration disc.

[0016] 2. By incorporating a drive assembly, the present invention enables the drive motor to rotate the second elastic packing material via a transmission belt and drive shaft during the wastewater treatment process. This allows the aerobic bacteria attached to the second elastic packing material to come into more uniform contact with the air pumped out by the aeration disc, thereby maintaining good activity of the aerobic bacteria on the entire second elastic packing material and improving the treatment efficiency and effect of aerobic bacteria on wastewater.

[0017] 3. By providing a baffle, the present invention can separate the activated sludge that falls into the collection hood when replacing the activated sludge, thereby achieving the removal of aged activated sludge without having to drain the wastewater in the aerobic zone.

[0018] 4. By incorporating spiral protrusions, when activated sludge is introduced into the aerobic zone, it can move downwards along the surface of the baffle under the influence of gravity. Subsequently, the downward-moving activated sludge can enter the gaps between multiple air inlets more evenly under the guidance of multiple spiral protrusions, thereby making the activated sludge more evenly distributed. This allows the aerobic bacteria in the activated sludge to attach more evenly to the second elastic packing, improving the treatment effect of aerobic bacteria on wastewater.

[0019] 5. The present invention is equipped with a scraper. When it is necessary to collect the aged active mud on the top of the isolation plate into the collection hood, as the drive motor drives the rotating wheel, one-way ring, baffle and isolation plate to rotate through the drive shaft, the scraper can scrape against the inner wall of the treatment tank under the action of the baffle, thereby avoiding the accumulation of active mud on the inner wall of the treatment tank.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] This invention provides, for example Figures 1 to 8 The wastewater reuse treatment equipment shown includes a cylindrical treatment tank 1, which is placed horizontally. Inside the treatment tank 1, along its axial direction, are arranged an anaerobic zone, an aerobic zone, and a sedimentation zone, which are completely separated by two vertical partitions 2. The partitions 2 are fixedly connected to the inner wall of the treatment tank 1. A first conveying pipe 3 connects the anaerobic zone and the aerobic zone, and a first water pump 4 is installed on the first conveying pipe 3. A second conveying pipe 5 connects the aerobic zone and the sedimentation zone, and a second water pump 6 is installed on the second conveying pipe 5. A first elastic packing material 7 and a second elastic packing material 8 are respectively arranged in the anaerobic zone and the aerobic zone. Rotating wheels 9, coaxial with the partitions 2, are arranged on both sides of the second elastic packing material 8. A first connecting rod 10 is fixedly connected between the rotating wheels 9 and the second elastic packing material 8. A drive assembly 11 is installed on the rotating wheel 9 near the anaerobic zone. A fixed shaft 12 is vertically fixedly connected to the center of the rotor 9 near the sedimentation zone. The fixed shaft 12 is vertically rotatably connected to the center of the partition 2 near the sedimentation zone. A collection hood 13 is provided on the bottom inner wall of the aerobic zone. An isolation component 14 is provided on the top of the collection hood 13. A one-way ring 15 is rotatably sleeved around the rotor 9. Multiple second connecting rods 16 are fixedly connected between the one-way ring 15 and the isolation component 14. An aeration disc 17 is installed inside the collection hood 13. A sewage pipe 18 is connected to the bottom of the collection hood 13. A sewage pump 19 is installed on the sewage pipe 18. Through holes 20 are provided at the top of the treatment tank 1 at positions opposite to the anaerobic zone, aerobic zone, and sedimentation zone. The first elastic packing 7 and the second elastic packing 8 are both composed of multiple sets of rectangular elastic packing individuals connected side by side. The multiple elastic packing individuals on the second elastic packing 8 are alternately distributed with multiple air inlet pipes 142.

[0031] During wastewater treatment, the pre-filtered wastewater is introduced into the anaerobic zone. Then, activated sludge is added into the anaerobic zone through the through-hole 20 at the top. Anaerobic bacteria in the activated sludge then attach to the first elastic packing 7. During wastewater treatment, the anaerobic bacteria on the first elastic packing 7 can treat some inorganic and some organic matter in the wastewater within the anaerobic zone. After the wastewater has been treated by the anaerobic bacteria, the first water pump 4 is started, pumping the treated wastewater into the aerobic zone through the first conveying pipe 3. Then, activated sludge is added into the aerobic zone through the through-hole 20 at the top. The activated sludge then accumulates on top of the isolation component 14, preventing it from directly falling onto the aeration disc 17 and obstructing it, thus ensuring unobstructed operation of the aeration disc 17. When activated sludge is added to the aerobic zone... Afterwards, the aerobic bacteria in the activated sludge can attach to the second elastic packing material 8. During wastewater treatment, the air produced by the aeration disc 17 can directly pass through the isolation component 14 and enter the area where the second elastic packing material 8 is located, thereby providing oxygen for the aerobic bacteria on the second elastic packing material 8. This ensures that the aerobic bacteria on the second elastic packing material 8 can treat some inorganic and some organic matter in the wastewater in the aerobic zone. During the process of air passing through the isolation component 14, the isolation component 14 can isolate and protect the activated sludge, preventing the activated sludge from directly contacting the oxygen in the air, thereby extending the service life of the activated sludge. After the wastewater is treated by the aerobic bacteria, the second water pump 6 can be started, thereby pumping the treated wastewater into the sedimentation zone through the second conveying pipe 5. After the wastewater in the sedimentation zone undergoes sedimentation, it can be discharged back into the external environment.

[0032] like Figures 3 to 7 As shown, the drive assembly 11 includes a drive shaft 111, which is vertically fixed to the center of the rotating wheel 9 near the anaerobic zone. The free end of the drive shaft 111 is vertically rotatably inserted into the center of the partition 2 near the anaerobic zone. A drive motor 112 is installed on the top of the treatment tank 1, and the drive motor 112 is located at the top of the drive shaft 111. A connection hole is opened on the top of the treatment tank 1 opposite to the output shaft of the drive motor 112. A transmission belt 113 is connected between the output shaft of the drive motor 112 and the drive shaft 111, and the transmission belt 113 passes through the connection hole.

[0033] The isolation assembly 14 includes an arc-shaped isolation plate 141, which is completely fitted to the inner wall of the treatment tank 1 and is fixedly connected to the second connecting rod 16. The width of the isolation plate 141 matches the distance between the two partitions 2. The arc length of the partition 2 is greater than the length of the collection hood 13. Multiple elongated air inlet pipes 142 are inserted side-by-side at the top of the isolation plate 141. The air inlet pipes 142 are arc-shaped, and their arc is the same as that of the isolation plate 141. The top and bottom of the intake pipe 142 are designed to be through, and a baffle 143 matching its length is provided at the top opening of the intake pipe 142. There is a gap between the baffle 143 and the top opening of the intake pipe 142, and the width of the baffle 143 is greater than the width of the intake pipe 142. Multiple small connecting blocks 144 are fixedly connected between the bottom of the baffle 143 and the top of the intake pipe 142. The main cross-section of the baffle 143 is rhomboid, and the diagonal side of the baffle 143 is centered at the top opening of the intake pipe 142.

[0034] Before adding activated mud into the aerobic zone, the isolation plate 141 is placed over the top of the collection hood 13. Then, activated mud is added into the aerobic zone. The activated mud can then gradually deposit on the top of the isolation plate 141 under the action of gravity. During the deposition of activated mud, since the top of the air inlet pipe 142 is equipped with a baffle 143, the activated mud can be prevented from falling into the aeration disc 17 in the collection hood 13 through the air inlet pipe 142, thereby preventing the aeration disc 17 from being blocked by the activated mud and ensuring the normal operation of the aeration disc 17. In addition, since the top surface of the baffle 143 is designed with a slope, when the activated mud falls on the top of the baffle 143, the activated mud can fall along the slope into the gap between two adjacent air inlet pipes 142.

[0035] When the aeration disc 17 is working, the air pumped out by the aeration disc 17 can enter the air inlet pipe 142 through the bottom opening of the air inlet pipe 142. When the air comes into contact with the baffle 143, the air can be guided by the inclined surface at the bottom of the baffle 143 and discharged from the air inlet pipe 142 along the gaps on both sides of the bottom of the baffle 143 and float upward. When the air comes into contact with the aerobic bacteria on the second elastic packing 8, the air can provide oxygen for the aerobic bacteria, thereby ensuring the treatment effect of the aerobic bacteria on the sewage. During this process, since the activated sludge is located in the gap between adjacent air inlet pipes 142, it can avoid direct contact between the activated sludge and the oxygen in the air, thereby extending the service life of the activated sludge. At the same time, it can also prevent the activated sludge from tumbling in the aerobic zone under the action of the gas pumped out by the aeration disc 17.

[0036] In addition, during the wastewater treatment process, the drive motor 112 can be started, which drives the drive shaft 111 to rotate through the transmission belt 113. As the drive shaft 111 rotates, the wheel 9 can rotate together with the drive shaft 111, while the one-way ring 15 can remain idle, thus ensuring the stationary state of the isolation plate 141. As the wheel 9 rotates, the second elastic packing 8 can rotate together, so that the aerobic bacteria attached to the second elastic packing 8 can come into more uniform contact with the air pumped out by the aeration disc 17, thereby ensuring that the aerobic bacteria on the entire second elastic packing 8 can maintain good activity, thereby improving the wastewater treatment efficiency and treatment effect of aerobic bacteria.

[0037] As wastewater treatment progresses, when the activated sludge in the aerobic zone ages, the drive motor 112 can rotate in reverse. As the drive motor 112 rotates in reverse, it can drive the rotating wheel 9, the one-way ring 15, and the isolation plate 141 to rotate via the drive shaft 111. As the isolation plate 141 gradually rotates upward, when the isolation plate 141 is in a vertical state, the activated sludge located in the gaps between the multiple air inlet pipes 142 can slide down into the collection hood 13 under the action of gravity. Then, the sewage pump 19 can be turned on to discharge the aged activated sludge through the sewage pipe 18.

[0038] like Figure 4 and Figure 5 As shown, an arc-shaped baffle 21 of the same size is fixedly connected to the rear edge of the isolation plate 141, and the baffle 21 is completely in contact with the inner wall of the treatment tank 1. A plurality of third connecting rods 22 are fixedly connected between the baffle 21 and the one-way ring 15.

[0039] With the baffle 21 installed, when the activated sludge ages and needs to be replaced, the drive motor 112 can be started to rotate the baffle 141 upwards. When the baffle 141 is in a vertical position, the activated sludge located in the gaps between the multiple air inlets 142 can slide down into the collection hood 13 under the influence of gravity. After the activated sludge on the baffle 141 is removed, the drive motor 112 is started again to rotate the baffle 141 and the baffle 21 together. When the baffle 21 rotates to the top of the collection hood 13, it can seal the top opening of the collection hood 13. Then the sewage pump 19 can be turned on, thus eliminating the need to empty the wastewater in the aerobic zone. The system can remove the activated sludge while simultaneously adding new activated sludge to the aerobic zone through the through-hole 20. The new activated sludge falls onto the top of the baffle 21. After the old activated sludge is removed, the drive motor 112 is started again, causing the baffle 141 to gradually reset and be positioned on top of the collection hood 13. During the resetting process of the baffle 141, the baffle 21 gradually becomes vertical. The new activated sludge that falls onto the top of the baffle 21 can then slide down to the top of the baffle 141 under the influence of gravity and be positioned in the gap between the multiple air inlet pipes 142, thereby preventing the activated sludge from directly contacting the air pumped in by the aeration disc 17.

[0040] like Figure 4 and Figure 5 As shown, multiple spiral protrusions 23 are arranged in parallel on the inner side of the baffle 21, and the ends of the multiple spiral protrusions 23 near the isolation plate 141 are alternately distributed with multiple air intake pipes 142.

[0041] With the spiral protrusions 23, when the activated mud is added to the aerobic zone, the drive motor 112 can be started in reverse, causing it to drive the rotating wheel 9, one-way ring 15, isolation plate 141, and baffle 21 to rotate via the drive shaft 111. After the baffle 21 completely covers the top opening of the collection hood 13, the drive motor 112 stops. At this time, the activated mud is added to the aerobic zone through the through hole 20 at the top of the aerobic zone. The added activated mud can fall onto the top of the baffle 21 under the action of gravity. After the activated mud has been added and settled on the top of the baffle 21, the drive motor 112 is started to continue rotating in reverse. At this time, the baffle 21 receiving the activated sludge can gradually deflect upwards, while the isolation plate 141 gradually moves towards the top of the collection hood 13. During this process, as the baffle 21 gradually tilts upwards, the activated sludge can move downwards along the surface of the baffle 21 under the action of gravity. Subsequently, the downward-moving activated sludge can enter the gap between the multiple air inlets 142 more evenly under the guidance of the multiple spiral protrusions 23, so that the activated sludge can be distributed more evenly, thereby allowing the aerobic bacteria in the activated sludge to attach more evenly to the second elastic packing 8, improving the treatment effect of aerobic bacteria on sewage.

[0042] like Figure 5 As shown, both sides of the baffle 21 and the isolation plate 141 protrude towards the axis of the processing tank 1. A scraper 24 is provided on the side of the baffle 21 away from the isolation plate 141. The two sides of the scraper 24 are rotatably connected to the two protrusions on both sides of the baffle 21 by a torsion spring, and the scraper 24 can be in contact with the inner wall of the processing tank 1 under the action of the torsion spring.

[0043] With the scraper 24 installed, when it is necessary to collect the aged active mud on the top of the isolation plate 141 into the collection hood 13, as the drive motor 112 drives the rotating wheel 9, one-way ring 15, baffle 21 and isolation plate 141 to rotate through the drive shaft 111, when the isolation plate 141 moves away from the top of the collection hood 13 and tilts downward, most of the active mud can slide into the collection tank from the position between the two adjacent air inlets 142 on the top of the isolation plate 141, while some of the active mud will fall onto the inner wall of the treatment tank 1. At this time, with the rotation of the baffle 21, the scraper 24 can scrape against the inner wall of the treatment tank 1 under the action of the baffle 21, thereby preventing the active mud from accumulating on the inner wall of the treatment tank 1.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
