Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a water treatment device based on biological ribbons. Background Art

[0002] In the critical period of current water resource protection and utilization, the effectiveness and reliability of sewage treatment technology are crucial. In sewage treatment scenarios, when the sewage has a high content of organic pollutants, such as domestic sewage, industrial wastewater from food processing and papermaking, etc., with excessive chemical oxygen demand (COD) and biochemical oxygen demand (BOD); excessive nitrogen and phosphorus nutrients, such as agricultural non-point source pollution, urban domestic sewage and some industrial wastewater causing the risk of water eutrophication; containing some heavy metals, such as sewage generated by industries such as mining, metallurgy, and electroplating; and there are requirements for treatment cost and ecological friendliness, such as small sewage treatment plants pursuing low-cost treatment, ecological parks, landscape water bodies, etc. expecting environmentally friendly treatment methods, biological ribbons are often needed for sewage treatment. As an important part of sewage treatment, biological ribbons are mainly used to treat various pollutants in sewage, including organic matter, nitrogen, phosphorus, and heavy metals, etc. It provides an attachment site for microorganisms, and the microorganisms on the formed biofilm can decompose and metabolize organic matter, converting it into harmless carbon dioxide and water; through the action of nitrifying bacteria and denitrifying bacteria, the conversion and removal of nitrogen in sewage are realized, converting ammonia nitrogen into nitrate nitrogen and then reducing it to nitrogen gas; by using the uptake and release of phosphorus by polyphosphate-accumulating bacteria under aerobic and anaerobic conditions, phosphorus removal is achieved by discharging excess sludge; in addition, microorganisms can also reduce the content of heavy metals in sewage through adsorption and other effects.

[0003] However, in the prior art, there are still the following problems in the process of treating sewage with biological ribbons:

[0004] In traditional sewage treatment processes, biological ribbons are usually laid in the reaction tank in a static suspension manner, relying only on the natural flow of sewage to come into contact with the ribbons. This static setting method makes the contact efficiency between biological ribbons and sewage remain at a relatively low level for a long time, making it difficult to meet the growing sewage treatment requirements. The removal of pollutants in sewage highly depends on the microbial flora attached to the surface of biological ribbons. When the contact efficiency between biological ribbons and sewage is low and the contact area is insufficient, pollutant molecules are difficult to fully diffuse to the area where the microbial flora is located, which makes it impossible for microorganisms to timely adsorb organic pollutants, nitrogen, phosphorus and other nutrients in sewage, thereby causing the degradation process to be blocked, and ultimately resulting in the sewage treatment effect failing to reach the expected standard.

[0017] Beneficial effects of the present invention:

[0018] 1. In the present invention, the vertical shaft is driven to rotate by a motor, which drives the first fixed sleeve and the first eccentric shaft to rotate, and the second eccentric shaft is driven by the transmission rod to make the vertical tube reciprocate, thereby driving the installation cross bar and the biological streamer to swing back and forth. This structure changes the traditional static suspension method of the biological streamer, greatly increases the contact area between the biological streamer and the sewage, helps the microbial flora to better adsorb and degrade pollutants in the sewage, and significantly improves the sewage treatment effect.

[0019] 2. In the present invention, when the vertical shaft rotates, the toggle disk rotates synchronously, and the toggle column at the lower part cooperates with the groove on the intermittent turntable, so that the intermittent turntable rotates intermittently, driving the air supply pipe, the horizontal pipe and the vertical aeration pipe to rotate. During the rotation of the vertical aeration pipe, on the one hand, the friction with the water body drives the local water flow, and on the other hand, the air jet discharged from the vertical aeration pipe promotes the flow of the water body, and as the vertical aeration pipe rotates, the direction of the air jet changes continuously, stirring the water body in a larger range; the vertical aeration pipe rotates and stays alternately, which enhances the mixing effect of the water body, promotes the full mixing of dissolved oxygen, nutrients and microorganisms, and improves the self-purification ability and treatment efficiency of the water body.

[0020] 3. In the present invention, the regulating component can automatically adjust the water flow rate of the first drainage channel according to the change of the water level of the second treatment tank. When the water level of the second treatment tank rises, the floating block is driven by the buoyancy to move the vertical lifting rod and the horizontal lifting rod upward, and the pull rope is pulled to move the valve plate downward, thereby reducing the water flow rate of the first drainage channel. When the water level drops, the floating block drives the relevant components downward due to gravity, and the second spring pushes the horizontal bar and the valve plate upward to increase the water flow rate, thereby maintaining the relative balance of the water level in the second treatment tank.

[0021] 4. In the present invention, the sewage is preliminarily treated by the sedimentation recess and the filter screen in the first treatment tank. After the sewage enters the first treatment tank, the sediment settles in the sedimentation recess and the filter screen intercepts large particles of impurities, thereby reducing the burden of subsequent treatment and improving the overall treatment efficiency.

[0036] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0037] Embodiment 1

[0038] Referring to Figures 1 to 9 , a water treatment device based on biological ribbons is provided, which includes a first treatment tank 1 and a second treatment tank 2. A mounting frame 3 is fixedly connected to the top of the second treatment tank 2. A plurality of ribbon components 4 are equidistantly installed on the mounting frame 3, and an aeration component 5 is installed on the ribbon component 4. The ribbon component 4 includes a vertical rotating pipe 41, the vertical rotating pipe 41 is rotatably connected to the mounting frame 3, and a plurality of groups of ribbon assemblies are circumferentially arranged on the outer circumference of the vertical rotating pipe 41. The ribbon assembly includes a plurality of mounting cross bars 410 arranged equidistantly from top to bottom. One end of the mounting cross bar 410 is fixedly connected to the outer wall of the vertical rotating pipe 41, and biological ribbons 42 are fixedly connected to the mounting cross bars 410. A second fixing sleeve 49 is fixedly sleeved on the upper part of the vertical rotating pipe 41, a second eccentric shaft 47 is fixedly connected to the bottom of the second fixing sleeve 49, a motor 43 is fixedly connected to the wall of the mounting frame 3, the motor 43 is connected to an external control switch through a wire, and the motor 43 is controlled to work through the external control switch. A vertical rotating shaft 44 is rotatably connected through the mounting frame 3, the top end of the vertical rotating shaft 44 is fixedly connected to the rotating end of the motor 43, a first fixing sleeve 48 is fixedly sleeved on the bottom end of the vertical rotating shaft 44, a first eccentric shaft 45 is fixedly connected to the bottom of the first fixing sleeve 48, a transmission rod 46 is rotatably sleeved on the outside of the first eccentric shaft 45, and one end of the transmission rod 46 is rotatably sleeved on the second eccentric shaft 47.

[0039] Furthermore, the second treatment tank 2 is arranged above the first treatment tank 1, and the lower part of one side of the first treatment tank 1 is connected to a first drainage channel 11, the outlet end of the first drainage channel 11 is located above the second treatment tank 2, and an adjusting component 6 is installed on the first drainage channel 11. The lower side of the second treatment tank 2 is connected to a second drainage channel 21, and the treated water in the second treatment tank 2 is discharged through the second drainage channel 21.

[0040] Furthermore, a first drainage channel 11 is connected to the lower part of one side of the first treatment tank 1 , a sedimentation recess 13 is provided at the lower inner part of the first treatment tank 1 , and a filter screen 12 is fixedly connected to the inner side of the first treatment tank 1 .

[0041] In the above, the sewage to be treated is transported to the first treatment tank 1 and enters the area above the sedimentation recess 13. Under the action of gravity, the sediment in the sewage naturally settles and accumulates in the sedimentation recess 13. Then, the water flows through the filter 12. The filter 12 plays an intercepting role, blocking the large particles of impurities in the sewage on one side to prevent them from entering the second treatment tank 2 with the water flow. The sewage after preliminary sedimentation and filtration flows into the second treatment tank 2 through the first drainage channel 11, completing the pretreatment process of the sewage and reducing the burden for subsequent treatment.

[0042] In the above, the vertical shaft 44 is driven to rotate synchronously by the motor 43. The rotation of the vertical shaft 44 causes the first fixed sleeve 48 fixed at its bottom to rotate accordingly. The first fixed sleeve 48 drives the first eccentric shaft 45 at the bottom to make a circular motion. The circular motion of the first eccentric shaft 45 transmits power through the transmission rod 46, thereby driving the second eccentric shaft 47 to move, and then causing the vertical tube 41 to reciprocate. The reciprocating rotation of the vertical tube 41 drives the installation cross bar 410 arranged on the outer side of the circular array to move synchronously, and the biological streamer 42 fixedly connected to the installation cross bar 410 swings back and forth accordingly. Microbial flora including bacteria, fungi, protozoa, etc. are attached to the surface of the biological streamer 42. These microbial flora form a dense biofilm. In the process of full contact between the biological streamer 42 and the sewage, the biofilm plays an adsorption and degradation role, removes organic pollutants in the sewage such as COD, BOD, nitrogen and phosphorus nutrients and some heavy metals, etc., to achieve biological treatment of sewage and effectively purify water quality.

[0043] Embodiment 2

[0044] Further, see Figures 1 to 11 On the basis of the first embodiment, the aeration component 5 includes an air supply pipe 51, which is rotatably connected to the mounting frame 3, and the vertical rotating pipe 41 is rotatably sleeved on the outside of the air supply pipe 51, and the bottom end of the air supply pipe 51 is connected to a horizontal pipe 58, and the upper part of the horizontal pipe 58 is equidistantly connected to a plurality of vertical aeration pipes 59.

[0045] Further, a sliding vertical column 510 is arranged inside the vertical air supply pipe 59. The sliding vertical column 510 penetrates through and is slidably connected to the horizontal pipe 58. A sealing block 512 is provided at the top end of the vertical air supply pipe 59. The top end of the sliding vertical column 510 is fixedly connected to the bottom of the sealing block 512. A first spring 511 is sleeved outside the sliding vertical column 510. The bottom end of the first spring 511 is fixedly connected to the inner wall of the horizontal pipe 58, and the top end of the first spring 511 is fixedly connected to the bottom of the sealing block 512.

[0046] An intermittent turntable 52 is fixedly sleeved on the upper part of the air supply pipe 51. A plurality of grooves 57 are circumferentially and arrayedly formed on the outer side of the intermittent turntable 52. An arc-shaped recess 56 is formed between two adjacent grooves 57 on the outer side of the intermittent turntable 52. A dial 53 is fixedly sleeved on the outer side of the vertical rotating shaft 44. A dialing column 54 is fixedly connected to the lower part of the dial 53. An arc-shaped avoidance part 55 is formed on one side of the upper outer side of the dial 53.

[0047] Further, the dialing column 54 is correspondingly arranged and adapted to the groove 57, and the arc-shaped recess 56 is adapted to the upper outer surface of the dial 53.

[0048] Further, a rotary joint 7 is fixedly connected to the top end of the air supply pipe 51, and a connecting pipe 8 is communicated with the top end of the rotary joint 7.

[0049] In the above, while the vertical rotating shaft 44 rotates, the dial 53 fixedly sleeved on its outer side also rotates synchronously. The dialing column 54 fixedly connected to the lower part of the dial 53 makes a circular motion along with the dial 53. When the dialing column 54 corresponds to and enters one of the grooves 57, the dialing column 54 pushes the intermittent turntable 52 to rotate a certain angle, so that the intermittent turntable 52 rotates once. When the dialing column 54 moves out of the groove 57, the arc-shaped recess 56 fits with the upper outer side of the dial 53. At this time, the dial 53 continues to rotate, but the intermittent turntable 52 remains stationary, so that the dial 53 drives the intermittent turntable 52 to rotate once every time it rotates one circle.

[0050] In the above, when the intermittent turntable 52 rotates, it drives the air supply pipe 51 to rotate synchronously, and further drives the horizontal pipe 58 and the vertical air supply pipe 59 to rotate synchronously. The top end of the air supply pipe 51 is connected to the connecting pipe 8 through the rotary joint 7. The connecting pipe 8 is connected to external air conveying equipment such as an air compressor and a vacuum pump. Air enters the air supply pipe 51 through the connecting pipe 8 and the rotary joint 7, and then enters the horizontal pipe 58 and the vertical air supply pipe 59 in sequence. As the air pressure in the vertical air supply pipe 59 gradually increases, the air pressure pushes the sealing block 512 to move upward against the elastic force of the first spring 511. The first spring 511 is elastically stretched, and the sealing block 512 no longer blocks the top end of the vertical air supply pipe 59. Air is discharged into the sewage through the top end of the vertical air supply pipe 59, and moreover, the air is guided in different directions through the edge of the sealing block 512.

[0051] In the above, when the vertical aeration pipe 59 rotates, on the one hand, the friction between it and the water body drives part of the water body to move, generating local water flow; on the other hand, the air jets entering the water body from different positions and angles impact the water body, pushing the water body to flow. And as the vertical aeration pipe 59 rotates, the direction of the air jets constantly changes, agitating the water body in a larger range. The rotation and stay of the vertical aeration pipe 59 are combined. When it rotates, it pushes the water body to flow, and when it stays, a relatively stable aeration area is formed locally. This alternating effect enhances the mixing effect of the water body, enabling the dissolved oxygen, nutrients, and microorganisms in the water body to be more fully mixed, improving the self-purification ability and treatment efficiency of the water body. When aeration is not required, the supply of gas to the air supply pipe 51 is stopped, the air pressure in the vertical aeration pipe 59 gradually decreases, the first spring 511 releases elastic potential energy, pulling the sealing block 512 to move downward, and re-sealing the top of the vertical aeration pipe 59.

[0052] Embodiment III

[0053] Further, referring to Figures 1 to 13 , on the basis of Embodiment II, the adjusting member 6 includes a valve plate 61. The valve plate 61 is slidably arranged inside the first drainage channel 11. The top end of the valve plate 61 penetrates through the first drainage channel 11 and extends to the outside and is fixedly connected with a cross bar 62. Two fixing blocks 65 are symmetrically and fixedly connected to the outer side wall of the first drainage channel 11. A lifting vertical rod 66 is slidably connected through the fixing block 65. The top end of the lifting vertical rod 66 is fixedly connected with a lifting cross bar 67. The bottom end of the lifting vertical rod 66 is fixedly connected with a floating block 68. The floating block 68 is arranged in the second treatment tank 2.

[0054] Further, a pulley 69 is rotatably connected to the outer side wall of the first drainage channel 11. An installation sleeve 610 is fixedly connected to the outer side wall of the first drainage channel 11. A pull rope 63 is fixedly connected to the bottom of the cross bar 62. The pull rope 63 passes through the installation sleeve 610, and the pull rope 63 bypasses the pulley 69 and is fixedly connected to the end of the lifting cross bar 67. A second spring 64 is sleeved on the outer side of the pull rope 63. The top end of the second spring 64 is fixedly connected to the bottom of the cross bar 62, and the bottom end of the second spring 64 is fixedly connected to the top of the installation sleeve 610.

[0055] In the above, when the water level in the second treatment tank 2 changes, the floating block 68 always floats on the water surface. When the water level in the second treatment tank 2 rises, the buoyancy of the water causes the floating block 68 to move upward. The floating block 68 drives the lifting vertical rod 66 fixedly connected thereto to move upward. The lifting cross rod 67 at the top of the lifting vertical rod 66 rises accordingly. The lifting cross rod 67 moves upward to pull the pull rope 63. The pull rope 63 bypasses the pulley 69, and the rotation of the pulley 69 assists the movement of the pull rope 63. After the pull rope 63 is subjected to a pulling force, it drives the cross bar 62, causing the valve plate 61 to move downward and slide into the first drainage channel 11. The gap between the valve plate 61 and the first drainage channel 11 becomes smaller, thereby reducing the water flow passing through the first drainage channel 11 and reducing the water supply to the second treatment tank 2.

[0056] In the above, when the water level in the second treatment tank 2 drops, the floating block 68 moves downward under its own gravity, driving the lifting vertical rod 66 and the lifting cross rod 67 to move downward. At this time, the pulling force of the lifting cross rod 67 on the pull rope 63 gradually decreases, and the elastic potential energy of the second spring 64 is gradually released. The second spring 64 pushes the cross bar 62 to drive the valve plate 61 to slide upward. The gap between the valve plate 61 and the first drainage channel 11 increases, increasing the water flow in the first drainage channel 11 and accelerating the water supply to the second treatment tank 2. In this way, the water level in the second treatment tank 2 can be maintained in a relatively balanced state, ensuring the stable operation of the entire water treatment device.

[0057] Refer to Figures 1 to 13 , the working principle of a water treatment device based on a biological ribbon provided by the present invention is as follows:

[0058] When in use, the sewage to be treated is transported to the first treatment tank 1, so that the sewage enters the area above the sedimentation recess 13 in the first treatment tank 1, and the sediment in the water accumulates in the sedimentation recess 13. The water further passes through the mesh of the filter 12 and enters the second treatment tank 2 through the first drainage channel 11. The large particles of impurities in the sewage are blocked on one side by the filter 12 and will not enter the second treatment tank 2 with the sewage flow. One end of the connecting pipe 8 is connected to an external air conveying device, such as an air compressor or a vacuum pump; the motor 43 is started, and the motor 43 drives the vertical shaft 44 to rotate, and the vertical shaft 44 drives the first fixed sleeve 48 to rotate, and the first fixed sleeve 48 drives the first eccentric shaft 45 to rotate, and the first The eccentric shaft 45 moves in a circular motion to drive the transmission rod 46 to move, the transmission rod 46 drives the second eccentric shaft 47 to move, the second eccentric shaft 47 drives the second fixed sleeve 49 to make the vertical rotating tube 41 reciprocate, the reciprocating rotation of the vertical rotating tube 41 drives the installation cross bar 410 to make the biological streamer 42 reciprocate, thereby increasing the contact area between the biological streamer 42 and the sewage, and the microbial flora including bacteria, fungi, protozoa, etc. attached to the surface of the biological streamer 42 form a dense biofilm, and organic pollutants such as COD, BOD, nitrogen and phosphorus nutrients and some heavy metals in the sewage are removed by adsorption and degradation, thereby improving the sewage treatment effect of the biological streamer 42; while the vertical rotating shaft 44 rotates, it drives the dial 53 The toggle plate 53 drives the toggle column 54 to move in a circle. When the toggle column 54 corresponds to one of the grooves 57 and enters the groove 57, the toggle column 54 pushes the intermittent turntable 52 to rotate a certain angle, so that the intermittent turntable 52 rotates once, and the arc-shaped avoidance portion 55 is used to avoid the intermittent turntable 52. When the toggle column 54 moves out of the groove 57, one of the arc-shaped recesses 56 fits with the upper outer side of the toggle plate 53, so that when the toggle plate 53 rotates, the intermittent turntable 52 remains stationary. Each rotation of the toggle plate 53 drives the intermittent turntable 52 to rotate once. When the intermittent turntable 52 rotates, it drives the air supply pipe 51 to rotate synchronously. When the intermittent turntable 52 stops, the air supply pipe 51 also rotates synchronously. Rotate, connect the air supply pipe 51 and the connecting pipe 8 through the rotating joint 7, so that when the air supply pipe 51 rotates, the connecting pipe 8 will not rotate, and can maintain connection for air transportation, the air enters the air supply pipe 51 through the connecting pipe 8 and the rotating joint 7, and enters the horizontal pipe 58 through the air supply pipe 51 and then enters the vertical aeration pipe 59, as the air pressure in the vertical aeration pipe 59 gradually increases, the air pressure pushes the sealing block 512 to move upward, the first spring 511 is elastically stretched, so that the sealing block 512 no longer blocks the top of the vertical aeration pipe 59, the air is discharged into the sewage through the top of the vertical aeration pipe 59, and the air is guided to different directions by the edge of the sealing block 512;The intermittent turntable 52 rotates once to drive the air supply pipe 51, causing the horizontal pipe 58 to rotate once. The horizontal pipe 58 drives the vertical aeration pipe 59 to rotate synchronously. Each time the intermittent turntable 52 rotates, the vertical aeration pipe 59 also rotates once. Thus, after the vertical aeration pipe 59 rotates a certain angle and stops, it provides oxygen to the sewage. During the rotation of the horizontal pipe 58 and the vertical aeration pipe 59, they will come into contact with and rub against the water body, thereby driving the part of the water body in contact with them to move along, generating local water flow. Moreover, during the continuous aeration process of the vertical aeration pipe 59, air is continuously released into the water. When the vertical aeration pipe 59 rotates, air enters the water body from different positions and angles, and the formed air jet will generate an impact force on the water body. This impact force will push the water body to flow. And as the vertical aeration pipe 59 rotates, the direction of the air jet is also constantly changing, thus stirring the water body in a larger range. The combination of the rotation and stop of the vertical aeration pipe 59 can generate a unique water flow pattern. When rotating, it pushes the water body to flow, and when stopping, a relatively stable aeration area is formed locally. This alternating effect can enhance the mixing effect of the water body, enabling the dissolved oxygen, nutrients, and microorganisms in the water body to be more fully mixed, improving the self-purification ability and treatment efficiency of the water body. When aeration is not required, the supply of gas to the air supply pipe 51 is stopped, and the air pressure gradually decreases. The elastic potential energy of the first spring 511 is released, thereby pulling the sealing block 512 downward to block the top of the vertical aeration pipe 59. As the water level in the second treatment tank 2 rises, the floating block 68 always remains floating on the water surface. When the water level in the second treatment tank 2 is relatively high, under the buoyancy of the water, the floating block 68 moves upward. The floating block 68 drives the lifting vertical rod 66 to make the lifting cross rod 67 move upward. The upward movement of the lifting cross rod 67 pulls the pull rope 63, and the pulley 69 rotates to assist the movement of the pull rope 63. After the pull rope 63 is subjected to a pulling force, it drives the cross bar 62 to make the valve plate 61 slide into the first drainage channel 11, thereby reducing the gap between the valve plate 61 and the first drainage channel 11, and further reducing the water flow rate passing through the first drainage channel 11, thus reducing the water supply to the second treatment tank 2. When the water level in the second treatment tank 2 drops, the floating block 68 moves under the action of its own gravity and always remains floating on the water surface in the second treatment tank 2. The downward movement of the floating block 68 drives the lifting vertical rod 66 to make the lifting cross rod 67 move downward. At this time, the pulling force of the lifting cross rod 67 on the pull rope 63 gradually decreases, and the elastic potential energy of the second spring 64 is gradually released. The second spring 64 pushes the cross bar 62 to drive the valve plate 61 to slide upward. At this time, the gap between the valve plate 61 and the first drainage channel 11 increases again, thereby increasing the water flow rate in the first drainage channel 11, thus accelerating the water supply to the second treatment tank 2. In this way, the water level in the second treatment tank 2 can be maintained in a relatively balanced state.;
