Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a wastewater treatment system and a wastewater treatment method thereof. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. The general wastewater treatment process consists of three stages: primary treatment, which involves coarse and fine screens, grit chambers, primary sedimentation tanks, dissolved air flotation tanks, and equalization tanks; secondary treatment, which adjusts the quantity and quality of the wastewater and balances its acidity and alkalinity; and tertiary treatment, which removes bacteria, heavy metals, and other small-molecule chemicals from the wastewater.

[0003] Currently, high-efficiency sedimentation tanks are widely used in wastewater treatment. Existing high-efficiency sedimentation tanks generally include mixing tanks, flocculation tanks, and settling tanks. After settling in the settling tank, the sludge is transported to the coagulation zone for circulation. High-efficiency sedimentation tanks are mostly inclined plate sedimentation tanks, which have inclined plates installed in the sedimentation tank. The sludge in the water settles on the inclined plates, the water rises along the inclined plates, and the separated sludge slides down the inclined plates under the action of gravity and is then discharged.

[0004] For example, patent application CN112174379A discloses a high-efficiency sedimentation tank, including a mixing tank, a flocculation tank, and a sedimentation tank. The mixing tank is connected to the flocculation tank, and the flocculation tank is connected to the sedimentation tank. A sludge scraper is fixed inside the sedimentation tank. An inclined plate assembly is provided on the upper inner side of the sedimentation tank. The inclined plate assembly includes multiple connected inclined plates. A first spray pipe is provided below the inclined plate assembly. The first spray pipe is provided with multiple inclined first nozzles. The inclination direction of the first nozzles is the same as the inclination direction of the inclined plates. The inclined plate assembly is connected to a moving device. The moving device drives the inclined plate assembly to move upward or downward relative to the sedimentation tank. Multiple water collection tanks are provided above the inclined plate assembly.

[0005] However, after the raw water passes through the flocculation tank, the flocs increase in size. The flocs flow with the raw water to the plug flow zone between the flocculation tank and the sedimentation tank and enter the sedimentation tank. Due to the increased volume and weight of the flocs, they are prone to accumulate in the second water passage and the third baffle, which causes a significant obstruction to water flow and affects the treatment efficiency of the raw water. Summary of the Invention

[0006] To improve the efficiency of raw water treatment, this application provides a wastewater treatment system and a wastewater treatment method thereof.

[0007] Firstly, the wastewater treatment system provided in this application adopts the following technical solution:

[0008] A wastewater treatment system includes a mixing tank, a flocculation tank, and a sedimentation tank. The flocculation tank is located between the mixing tank and the sedimentation tank. A first partition and a second partition are provided between the flocculation tank and the sedimentation tank. A first water passage is formed between the first partition and the bottom of the flocculation tank. A flow zone is formed between the first partition and the second partition and is connected to the sedimentation tank. An installation frame is rotatably arranged below the first partition and within the water passage. The installation frame includes a rotating shaft and an installation frame disposed on the rotating shaft. The installation frames are spaced apart and evenly distributed along the circumference of the rotating shaft. A non-permeable fabric is disposed within the installation frame. The edge of the non-permeable fabric is fixedly disposed within the installation frame. When the installation frame rotates, the non-permeable fabric protrudes outward in the direction opposite to the rotation direction of the installation frame. A flow-driving element is provided within the flow zone. The flow-driving element is used to drive the non-permeable fabric to protrude outward in the direction opposite to the bottom of the flow zone after the installation frame enters the flow zone, thereby removing the flocculated material.

[0009] Optionally, the propulsion component includes a water spray pipe and a water pump disposed at the bottom of the propulsion zone. The water pump is located in the upper clear liquid of the sedimentation tank. One end of the water spray pipe is connected to the water outlet of the water pump, and the other end is embedded in the bottom of the propulsion zone.

[0010] Optionally, multiple water spray pipes are provided and interconnected, with the water outlet of each water spray pipe located directly below the non-permeable fabric and evenly distributed along the length of the mounting frame.

[0011] Optionally, four mounting frames are provided. A push switch is provided on the side wall of the first water passage. The push switch is electrically connected to the water pump. After the mounting frame rotates into the first water passage, the mounting frame squeezes the push switch to turn on the water pump and deliver water to impact the non-permeable fabric below, removing the flocculent material inside the non-permeable fabric.

[0012] Optionally, the water spray pipe is recessed to the bottom of the flow propulsion zone, and an installation groove is provided at the bottom of the flow propulsion zone and around the water spray pipe. The water outlet of the water spray pipe is located on the bottom wall of the installation groove. A baffle is rotatably installed in the installation groove, and the rotation axis of the baffle is parallel to the bottom wall of the installation groove. After the baffle rotates into the installation groove, it is used to block the water spray pipe. When the water spray pipe delivers water, the water flow pushes open the baffle.

[0013] Optionally, an installation shaft is rotatably disposed within the installation groove, a baffle is fixedly disposed on the installation shaft, and a torsion spring is sleeved on the installation shaft. One side of the torsion spring is fixedly disposed on the installation shaft, and the other side is fixedly disposed on the side wall of the installation groove. The torsion spring drives the baffle to have a rotational tendency toward the installation groove.

[0014] Optionally, a sliding plate is provided at the bottom of the flow-pushing zone, the mounting groove is formed on the sliding plate, the sliding plate abuts against the second partition plate, the sliding plate is slidably disposed in the flow-pushing zone, the sliding plate slides along the depth direction of the flow-pushing zone, and a driving component is also included for driving the sliding plate to slide.

[0015] Optionally, the driving component includes a winch mounted on the second partition, the winch being located on one side of the sedimentation tank, the winch having two wire ropes wound on it, the two wire ropes being wound in opposite directions, one wire rope being fixedly connected to the sliding plate from above the second partition, and the other wire rope being fixedly connected to the sliding plate from below the second partition.

[0016] Optionally, a guide rail is fixedly installed on the second partition, the guide rail extends from the top of the second partition to one side of the sedimentation tank, the guide rail is dovetail-shaped, and the sliding plate is slidably engaged on the guide rail.

[0017] Secondly, this application provides a wastewater treatment method, which adopts the following technical solution:

[0018] Optionally, a wastewater treatment method for a wastewater treatment system further includes;

[0019] S1: After the raw water passes through the mixing tank and flocculation tank, the sediment in the raw water flocculates into the flocculation tank;

[0020] S2: The rotating shaft rotates, causing the mounting frame to move. The mounting frame rotates counterclockwise. As the mounting frame rotates, under the action of the original water resistance, the non-permeable fabric moves outward and protrudes in the direction away from the rotation of the mounting frame to form a storage groove.

[0021] S3: The flocculent enters the collection tank and moves toward the push flow area. When the water pump of the installation frame is started, the water pump draws raw water to impact the underside of the non-permeable fabric, causing the non-permeable fabric to flip outward to remove the flocculent in the collection tank.

[0022] S4: After a long period of sewage treatment, start the winch. The winch drives the sliding plate to move along the guide rail and enter the sedimentation tank, moving the flocs in the push flow zone into the sedimentation tank.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. After passing through the mixing tank and flocculation tank, the volume and mass of the flocs increase, causing them to settle to the bottom of the flocculation tank. Driven by the water flow, the flocs flow to the first water passage. At this point, the rotating shaft drives the mounting frame to rotate, which in turn moves the impermeable cloth. Under the resistance of the sewage, the impermeable cloth becomes concave and captures the flocs. The flocs follow the rotating mounting frame to the plugging zone, where they are then pushed by the plugging element onto the impermeable cloth. The impermeable cloth flips outward, removing the flocs. After being removed, the flocs flow through the plugging zone into the sedimentation tank. This process reduces the likelihood of flocs accumulating at the first water passage and at the second baffle, thereby reducing the possibility of floc blockage and further reducing the obstruction of sewage flow, thus improving sewage treatment efficiency.

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a wastewater treatment system. (Refer to...) Figure 1 and Figure 2 The wastewater treatment system includes a mixing tank 1, a flocculation tank 2, and a sedimentation tank 3. The flocculation tank 2 is located between the mixing tank 1 and the sedimentation tank 3. A first baffle 4 and a second baffle 5 are provided between the flocculation tank 2 and the sedimentation tank 3. A first water passage 6 is opened between the first baffle 4 and the bottom of the flocculation tank 2. A plug flow zone 7 is formed between the first baffle 4 and the second baffle 5. The plug flow zone 7 is connected to the sedimentation tank 3. During wastewater treatment, after the wastewater passes through the mixing tank 1 and the flocculation tank 2, the volume and mass of the flocs increase and they sink to the bottom of the flocculation tank 2. Driven by the water flow, the flocs flow to the first water passage 6 and enter the plug flow zone 7, and then through the plug flow zone 7 to the sedimentation tank 3.

[0035] In the embodiments of this application, reference is made to Figure 2 and Figure 3 Below the first partition 4 and inside the water passage, an installation frame is rotatably installed. The installation frame includes a rotating shaft 8 and an installation frame 9 installed on the rotating shaft 8. Further, a waterproof motor 10 is fixedly installed outside the flocculation tank 2. The rotating shaft 8 is coaxially installed on the output shaft of the waterproof motor 10. The installation frames 9 are spaced apart and evenly arranged around the circumference of the rotating shaft 8. A non-permeable fabric 11 is installed inside the installation frame 9. The edge of the non-permeable fabric 11 is fixed inside the installation frame 9. When the installation frame 9 rotates, the non-permeable fabric 11 protrudes outward in the direction away from the rotation direction of the installation frame 9. A flow-pushing element is installed in the flow-pushing zone 7. The flow-pushing element is used to drive the non-permeable fabric 11 to protrude outward in the direction away from the bottom of the flow-pushing zone 7 after the installation frame 9 enters the flow-pushing zone 7, thereby removing the flocculants.

[0036] When the flocculents pass through the first water passage 6, the waterproof motor 10 is activated. The waterproof motor 10 drives the rotating shaft 8 to rotate, which in turn drives the mounting frame 9 to rotate. The rotation of the mounting frame 9 causes the non-permeable fabric 11 to move. Under the action of sewage resistance, the non-permeable fabric 11 is concave and captures the flocculents. The flocculents follow the rotation of the mounting frame 9 to the flow propulsion zone 7. Subsequently, the flow propulsion component acts on the non-permeable fabric 11, causing the non-permeable fabric 11 to flip outward and remove the flocculents. After the flocculents are removed, they pass through the flow propulsion zone 7 into the sedimentation tank 3. In the above process, the possibility of flocculents accumulating at the first water passage 6 and the possibility of flocculents accumulating at the second baffle 5 are reduced, thereby reducing the possibility of flocculent blockage and thus reducing the obstruction of sewage flow, thereby improving sewage treatment efficiency.

[0037] Reference Figure 2 and Figure 3In this embodiment, the propulsion component includes a water spray pipe 12 and a water pump 13 disposed at the bottom of the propulsion zone 7. The water pump 13 is located in the upper clear liquid of the sedimentation tank 3. One end of the water spray pipe 12 is connected to the water outlet of the water pump 13, and the other end is embedded in the bottom of the propulsion zone 7. The water outlet of the water spray pipe 12 is directly below the non-permeable fabric 11. When the non-permeable fabric 11 moves to the propulsion zone 7, the water pump 13 is started. The water pump 13 draws clean water and impacts the bottom of the non-permeable fabric 11 through the water spray pipe 12, causing the non-permeable fabric 11 to turn outward and remove the flocculent. The operation is simple and convenient. At the same time, the flocculent is captured in the non-permeable fabric 11 and removed by the spray of clean water. In this process, the possibility of flocculent breakage is reduced, thereby improving the flocculation effect. At the same time, under the action of the water spray pipe 12 and the water pump 13, it is easy to push the flocculent in the propulsion zone 7 to move, thereby reducing the possibility of flocculent settling in the propulsion zone 7.

[0038] Reference Figure 2 and Figure 3 Furthermore, in this embodiment of the application, multiple water spray pipes 12 are provided and interconnected. The water outlet of the water spray pipes 12 is located directly below the non-permeable fabric 11 and is evenly arranged along the length of the mounting frame 9.

[0039] Reference Figure 2 and Figure 3 To facilitate the intermittent starting of the water pump 13, in this embodiment, four mounting frames 9 are provided, which are evenly arranged around the circumference of the rotating shaft 8. A push switch is provided on the side wall of the first water passage 6 (started when pressed and disconnected when the pressing force is released). The push switch is electrically connected to the water pump 13. After the mounting frame 9 rotates into the first water passage 6, the mounting frame 9 squeezes the push switch, which turns on the water pump 13 and delivers water to impact the non-permeable fabric 11 and remove the flocculants inside the non-permeable fabric 11. When the mounting frame 9 rotates, when the mounting frame 9 squeezes the push switch, the mounting frame 9 located in the push flow zone 7 is in a horizontal state. At this time, the water pump 13 starts and drives the water pump 13 to spray out and act on the non-permeable fabric 11, thereby facilitating the removal of flocculants and reducing energy consumption.

[0040] Reference Figure 4 , Figure 5 and Figure 6To reduce the possibility of flocculants clogging the spray pipe 12, the spray pipe 12 is recessed to the bottom of the flow zone 7. An installation groove 14 is provided at the bottom of the flow zone 7 and around the spray pipe 12. The outlet of the spray pipe 12 is located on the bottom wall of the installation groove 14. A baffle 15 is rotatably installed inside the installation groove 14. The rotation axis of the baffle 15 is parallel to the bottom wall of the installation groove 14. After the baffle 15 rotates into the installation groove 14, it is used to block the spray pipe 12. When the spray pipe 12 delivers water, the water flow pushes open the baffle 15. When the outlet pipe does not deliver water, the baffle 15 is located in the installation groove 14 and closes the opening of the outlet pipe, thereby reducing the possibility of flocculants entering the outlet pipe. When the spray pipe 12 sprays water, the water flow pushes open the baffle 15 and the water flow passes through the installation groove 14 and acts on the non-permeable fabric 11.

[0041] Reference Figure 4 , Figure 5 and Figure 6 To facilitate the rotation of the baffle 15 into the mounting groove 14 when the water spray pipe 12 stops operating, the mounting groove 14 is rotatably mounted with a mounting shaft 16, and the baffle 15 is fixedly mounted on the mounting shaft 16. A torsion spring 17 is sleeved on the mounting shaft 16, with one side of the torsion spring 17 fixedly mounted on the mounting shaft 16 and the other side fixedly mounted on the side wall of the mounting groove 14. The torsion spring 17 drives the baffle 15 to rotate towards the mounting groove 14. When the water flow pushes open the baffle 15, the torsion spring 17 accumulates potential energy. When the water flow stops, under the action of the torque of the torsion spring 17, the baffle 15 is reversed and enters the mounting groove 14 to close the water spray pipe 12. The operation is simple and convenient.

[0042] Reference Figure 2 , Figure 5 and Figure 7 In this embodiment, a sliding plate 18 is provided at the bottom of the flow-pushing zone 7. The sliding plate 18 has the same cross-section as the flow-pushing zone 7 and is the bottom of the flow-pushing zone 7. An installation groove 14 is opened on the sliding plate 18 and passes through the sliding plate 18. The sliding plate 18 abuts against the second partition 5 and is slidably disposed in the flow-pushing zone 7. The sliding plate 18 slides along the depth direction of the flow-pushing zone 7. The embodiment also includes a driving component for driving the sliding plate 18 to slide. The driving component includes a winch 19 disposed on the second partition 5. The winch 19 is located on one side of the sedimentation tank 3. Two steel wire ropes 20 are wound on the winch 19. The winding directions of the two steel wire ropes 20 are opposite. One steel wire rope 20 is fixedly connected to the sliding plate 18 from above the second partition 5, and the other is fixedly connected to the sliding plate 18 from below the second partition 5.

[0043] When the wastewater treatment efficiency decreases, the winch 19 is started. The winch 19 winds up one wire rope 20 and unwinds the other wire rope 20. When the wire rope 20 is wound up, it drives the sliding plate 18 to move upward. When the sliding plate 18 moves upward, it moves the flocculent material deposited on the sliding plate 18. At the same time, it scrapes off the flocculent material on the first baffle 4 and the second baffle 5, thereby reducing the possibility of flocculent material clogging the push flow zone 7 and restoring the wastewater treatment efficiency. Then the winch 19 rotates in reverse, driving the sliding plate 18 to move downward to the initial position.

[0044] Reference Figure 2 , Figure 5 and Figure 7 To facilitate the sliding plate 18 in carrying the flocculants into the sedimentation tank 3, a guide rail 21 is fixedly installed on the second partition 5. The guide rail 21 extends from the top of the second partition 5 to one side of the sedimentation tank 3. The guide rail 21 is dovetail-shaped, and the sliding plate 18 is slidably engaged with the guide rail 21. The sliding plate 18 slides along the guide rail 21 and slides into the sedimentation tank 3, thereby facilitating the carrying of the flocculants into the sedimentation tank 3.

[0045] The implementation principle of a wastewater treatment system according to an embodiment of this application is as follows:

[0046] When the flocculents pass through the first water passage 6, the waterproof motor 10 is activated. The waterproof motor 10 drives the rotating shaft 8 to rotate, which in turn drives the mounting frame 9 to rotate. The rotation of the mounting frame 9 causes the non-permeable fabric 11 to move. Under the action of sewage resistance, the non-permeable fabric 11 is concave and captures the flocculents. The flocculents follow the rotation of the mounting frame 9 to the push flow zone 7. Subsequently, the water jet from the water pump 13 acts on the non-permeable fabric 11, causing the non-permeable fabric 11 to flip outward and remove the flocculents. After the flocculents are removed, they pass through the push flow zone 7 into the sedimentation tank 3. In the above process, the possibility of flocculents accumulating at the first water passage 6 and the possibility of flocculents accumulating at the second baffle 5 are reduced, thereby reducing the possibility of flocculent blockage and thus reducing the obstruction of sewage flow, thereby improving sewage treatment efficiency.

[0047] This application discloses a wastewater treatment method for a wastewater treatment system, which further includes:

[0048] S1: After the raw water passes through the mixing tank 1 and the flocculation tank 2, the sediment in the raw water is flocculated into the flocculation tank 2;

[0049] S2: Rotating shaft 8 drives the mounting frame 9 to move. The mounting frame 9 rotates counterclockwise. As the mounting frame 9 rotates, under the action of the original water resistance, the non-permeable fabric 11 moves outward and protrudes in the direction away from the rotation of the mounting frame 9 to form a storage groove.

[0050] S3: The flocculent enters the collection tank and moves toward the push flow zone 7. When the installation frame 9 starts the water pump 13, the water pump 13 draws raw water and impacts the underside of the non-permeable fabric 11, causing the non-permeable fabric 11 to flip outward to remove the flocculent in the collection tank.

[0051] S4: After long-term sewage treatment, start the winch 19. The winch 19 drives the sliding plate 18 to move along the guide rail 21 and enter the sedimentation tank 3, moving the flocculent in the push flow zone 7 into the sedimentation tank 3.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
