Description

Technical Field

[0001] This invention relates to the field of wastewater biological treatment technology, specifically to a continuous flow reaction device for a symbiotic system of microorganisms and aquatic plants. Background Technology

[0002] Existing wastewater treatment plants mostly use microbial, physical, and chemical treatment methods to treat wastewater, which then meets the effluent standards and is transported to natural water bodies. The wastewater continues to degrade through the self-purification function of the water body, thereby purifying the wastewater. However, this method generally increases the pressure on the aquatic ecosystem.

[0003] Existing wastewater treatment methods that rely on the self-purification function of water bodies primarily involve microbial degradation, such as the activated sludge process. This process involves continuously introducing air into the wastewater, which, after a certain period, results in the formation of sludge-like flocs due to the proliferation of aerobic microorganisms. These aerobic microorganisms have a strong ability to adsorb and oxidize organic matter. Similarly, when wastewater is introduced into natural water bodies, aerobic microorganisms are often used to degrade the residual organic matter. In existing technologies, various methods are needed to reduce the levels of organic matter, nitrogen, phosphorus, and other substances in the wastewater before discharge to prevent the growth of large amounts of organisms that could disrupt the ecological balance of the water body. Therefore, continuous flow reactors are often used in this process to achieve discharge standards through stirring, mixing, heating, and increasing the wastewater flow time.

[0004] In existing technologies, when wastewater comes into contact with organisms in aquatic bodies, leading to the growth of a large number of organisms, the main approach is to control the discharge of wastewater to different water bodies and different locations within the same water body through multiple pipelines and valves. This controls the amount of wastewater discharged and prevents the disruption of the ecological balance of the water body. However, since the purification of wastewater by water bodies takes a certain amount of time, the purification efficiency of water bodies can only be estimated. Due to human demand, chemical products need to be continuously produced, which leads to an increasing amount of wastewater discharged. Once wastewater is discharged for a long time, water pollution is inevitable. Summary of the Invention

[0005] To address the problems existing in the current technology, a continuous flow reaction device for microbial and aquatic plant symbiotic systems is provided.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A continuous flow reaction device for a microbial and aquatic plant symbiotic system includes a water body, a delivery pipeline, and the continuous flow reaction device itself. The water body includes microorganisms and aquatic plants. The continuous flow reaction device is located inside the water body, and both ends of the continuous flow reaction device are connected to the delivery pipeline.

The flow extension mechanism is used to control the flow rate of wastewater. The feeding assembly is connected to both the transmission pipeline and the water body. The feeding assembly is used to transfer microorganisms from the water body to the flow extension mechanism. The feeding assembly includes a blocking mechanism to prevent the water body from communicating with the flow extension mechanism.

[0008] The transmission pipe has two openings for communication with the feeding assembly. The feeding assembly includes a cover, an electromagnet, a drive block, a rotating mechanism, and an extension mechanism. The cover is fitted onto the outside of the transmission pipe, with a water inlet in the middle and abutment plates at both ends of the cover near the water inlet. The electromagnet is positioned between the cover and the transmission pipe, at both ends of the transmission pipe. The drive block is positioned at both ends of the abutment plates and is made of magnetic material. The rotating mechanism is positioned between the two drive blocks, with the two ends of the rotating mechanism forming a first water accumulation chamber and a second water accumulation chamber, respectively. The extension mechanism is positioned on the first and second water accumulation chambers and is used to adjust the distance between the drive block and the rotating mechanism.

[0009] When the first and second water collection chambers move toward the opening, the rotating mechanism and the second water collection chamber will first contact the abutment plate. The drive block on the first water collection chamber does not contact the sealing mechanism.

The flow extension mechanism includes a first guide plate and a second guide plate. Multiple first and second guide plates are provided. The first and second guide plates are arranged sequentially inside the transmission pipe. A first drainage hole is provided at the top of the first guide plate, and a second drainage hole is provided at the bottom of the second guide plate. A chamber is formed between the first and second guide plates. A flow extension channel for extending the flow distance of sewage is formed between the first drainage hole, the chamber, and the second drainage hole.

[0014] Preferably, the flow extension mechanism further includes a rotating wheel and a second motor. Multiple rotating wheels are arranged sequentially inside the chamber. The rotating wheels are rotatably connected to the chamber. The rotating wheels are used to collect and conduct sewage passing through the chamber. Both ends of the rotating wheels are provided with a rotating shaft and a transmission wheel rotatably connected to the rotating shaft. Two adjacent rotating wheels are connected through the transmission wheel. The second motor is connected to only one transmission wheel.

[0015] Preferably, the two openings are respectively located at the input end and the middle part of the transmission pipe. Both openings are provided with grooves. The sealing mechanism includes a sealing plate, a transmission plate, a transmission rod, and a second elastic element. The sealing plate is slidably disposed on the opening. The sealing plate is provided with a protrusion for inserting into the groove. The outer surface of the protrusion is made of flexible material. The protrusion and the groove are interference-fitted. The sealing plate located near the input end of the transmission pipe can directly contact the driving block. The sealing plate located near the middle part of the transmission pipe is connected to the transmission rod and the transmission plate. The transmission rod can contact the driving block. The second elastic element is used to connect the transmission pipe and the sealing plate.

The flow limiting mechanism includes a flow limiting bracket and a moving block. The flow limiting bracket is provided with a transmission hole. The moving block is connected to a blocking plate. The moving block is provided with a blocking block for blocking the transmission port. The blocking block is provided with multiple evenly distributed flow limiting channels.

[0018] The advantages of this invention compared to the prior art are as follows:

[0019] 1. This application utilizes aquatic plants to provide a habitat for microorganisms to live and reproduce, causing a large number of microorganisms to gather around the plants. Then, a feeding component transfers water containing microorganisms into a transmission pipe, allowing the wastewater in the transmission pipe to come into contact with and be degraded by the microorganisms. During this process, the wastewater transmission mechanism also controls the flow rate of the wastewater, thereby increasing the contact time and area between the wastewater and the microorganisms, and thus enhancing the degradation effect. The blocking component prevents large amounts of wastewater from being discharged from the feeding component and transferred into the water body, which could lead to excessive proliferation of organisms inside the water body and disrupt the ecological balance of the aquatic body.

[0020] 2. This application places the continuous flow reaction device inside the water body, allowing water to pass through the inlet and fill the first or second water accumulation chamber. Then, the magnetic force of the electromagnet causes the first and second water accumulation chambers to move between the casing and the transmission pipe. During this process, the rotating mechanism first contacts the abutment plate, sealing the first or second water accumulation chamber. Then, the driving block on the first or second water accumulation chamber contacts the sealing mechanism. At this time, the sealing mechanism opens the opening corresponding to the first or second water accumulation chamber, connecting the sealed first or second water accumulation chamber with this opening, and transferring the water containing microorganisms into the transmission pipe.

[0021] 3. This application uses the elastic force of the first elastic element to extend the push plate toward the rotating mechanism, thereby facilitating the push plate and the rotating mechanism to first abut against the abutment plate.

[0022] 4. This application delivers wastewater into a transmission pipeline via an infusion pipeline. Then, a sealing mechanism and a feeding assembly transfer microorganisms from the opening to the input end of the flow extension mechanism, allowing the wastewater and microorganisms to move together. At this time, the mixture of wastewater and microorganisms comes into contact with the first guide plate and the second guide plate and is guided by them, causing the mixture to move in the flow extension channel in the order of first drainage hole - chamber - second drainage hole. This process prolongs the movement distance of the mixture, thereby increasing the contact time between wastewater and microorganisms, making it easier for microorganisms to purify the wastewater.

[0023] 5. This application enhances the mixing effect of sewage and microorganisms through the stirring rod, thereby facilitating the degradation of sewage by microorganisms. Microorganisms passing through the opening in the middle of the transmission pipe will be transported along the channel formed between the outer wall of the guide tube and the inner wall of the transmission pipe. This process will cooperate with the flow limiting mechanism to facilitate the transfer of microorganisms into the inside of the guide tube and stir them with the stirring rod. This prevents microorganisms passing through the opening in the middle of the transmission pipe from being directly transferred without mixing with sewage, which would affect the mixing effect of microorganisms and sewage.

Detailed Implementation

[0036] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0037] like Figures 1 to 10 As shown; a continuous flow reaction device for a microbial and aquatic plant symbiotic system includes a water body, a delivery pipeline 1, and the continuous flow reaction device itself. The water body includes microorganisms and aquatic plants. The continuous flow reaction device is located inside the water body, and both ends of the continuous flow reaction device are connected to the delivery pipeline 1. The continuous flow reaction device is positioned close to the aquatic plants. The continuous flow reaction device includes a transmission pipeline 2, a flow extension mechanism 3, and a feeding assembly 4. The transmission pipeline 2 is connected to the delivery pipeline 1. The flow extension mechanism 3 is used to control the flow rate of wastewater. The feeding assembly 4 is connected to both the transmission pipeline 2 and the water body. The feeding assembly 4 is used to transfer microorganisms from the water body to the flow extension mechanism 3. The feeding assembly 4 includes a blocking mechanism 41 for preventing the water body from communicating with the flow extension mechanism 3.

[0038] It should be noted that the water body refers to natural rivers and lakes, specifically those containing at least microorganisms and aquatic plants. These microorganisms further degrade discharged wastewater. Because aquatic plants secrete substances that attract microorganisms, a large number of microorganisms gather around the plants. In this process, the microorganisms provide nutrients to the plants, and the plants provide a habitat for the microorganisms to survive and reproduce. Therefore, the continuous flow reactor is positioned close to the aquatic plants to facilitate the transfer of water containing microorganisms from the feed assembly 4 into the transmission pipe 2. This allows the wastewater in the transmission pipe 2 to come into contact with the microorganisms and be degraded. During this process, the wastewater transmission mechanism also controls the wastewater flow rate, thereby increasing the contact time and area between the wastewater and the microorganisms, enhancing the degradation effect. The blocking assembly prevents large amounts of wastewater from being discharged from the feed assembly 4 and transferred into the water body, which could lead to excessive biological proliferation and disrupt the ecological balance of the water body. Multiple continuous flow reactors can be installed to increase the wastewater purification efficiency.

[0039] The transmission pipe 2 has two openings 21 for communicating with the feeding assembly 4. The feeding assembly 4 includes a cover 42, an electromagnet 43, a drive block 44, a rotating mechanism 45, and an extension mechanism 46. The cover 42 is fitted onto the outside of the transmission pipe 2, and a water inlet 421 is provided in the middle of the cover 42. Abutment plates 422 are provided at both ends of the cover 42 at the water inlet 421. The electromagnet 43 is located between the cover 42 and the transmission pipe 2 and at both ends of the transmission pipe 2. The drive block 44 is located at both ends of the abutment plate 422 and is made of magnetic material. The rotating mechanism 45 is located between the two drive blocks 44, and the two ends of the rotating mechanism 45 and the drive blocks 44 respectively form a first water accumulation chamber 441 and a second water accumulation chamber 46. 42; The extension mechanism 46 is disposed on the first water accumulation chamber 441 and the second water accumulation chamber 442. The extension mechanism 46 is used to adjust the distance between the drive block 44 and the rotating mechanism 45. When the first water accumulation chamber 441 and the second water accumulation chamber 442 move toward the opening 21, the rotating mechanism 45 and the second water accumulation chamber 442 will first contact the abutment plate 422. The drive block 44 on the first water accumulation chamber 441 does not contact the sealing mechanism 41. When the drive block 44 on the first water accumulation chamber 441 contacts the sealing mechanism 41, the second water accumulation chamber 442 and the rotating wheel 33 mechanism are in contact with the abutment plate 422. The first water accumulation chamber 441 is connected to the opening 21 but not to the inlet 421. The second water accumulation chamber 442 is connected to the inlet 421.

[0040] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown; since the continuous flow reactor is located inside the water body, water can pass through the inlet 421 to fill the first water accumulation chamber 441 or the second water accumulation chamber 442. Then, the operator uses the magnetic force of the electromagnet 43 to move the first water accumulation chamber 441 and the second water accumulation chamber 442 between the casing 42 and the transmission pipe 2. During this process, the rotating wheel 33 mechanism first contacts the abutment plate 422, sealing the first water accumulation chamber 441 or the second water accumulation chamber 442. Only then will the driving block 44 on the first water accumulation chamber 441 or the second water accumulation chamber 442 contact the sealing mechanism 41, extending... The extension mechanism 46 will adjust the volume of the first water accumulation chamber 441 or the second water accumulation chamber 442 according to the actual situation, so that the first water accumulation chamber 441 and the second water accumulation chamber 442 can continue to move. Then the sealing mechanism 41 will open the opening 21 corresponding to the first water accumulation chamber 441 or the second water accumulation chamber 442, so that the first water accumulation chamber 441 or the second water accumulation chamber 442 in the sealed state is connected to the opening 21, and the water containing microorganisms will be transferred to the inside of the transmission pipe 2. At this time, the water accumulation chamber that is not connected to the opening 21 will be connected to the inlet 421 and will be filled with water. It should be noted that the first water collection chamber 441, the second water collection chamber 442, and the rotating wheel 33 mechanism are all provided with protrusions, and the abutment plate 422 is provided with a recess corresponding to the protrusion. A sealing ring 4513 is provided between the protrusion and the recess to prevent the water inlet 421 from communicating with the opening 21. A filter screen is also provided on the outside of the cover 42 to prevent plant leaves from passing through the water inlet 421 and entering the first water collection chamber 441, the second water collection chamber 442, and the transmission pipe 2, which would affect the transmission of sewage and microorganisms.

[0041] The extension mechanism 46 includes a push plate 461 and a rotating plate 462. The push plate 461 is rotatably connected to the drive block 44. The push plate 461 is provided with a lever 4611 extending toward the rotating mechanism 45. The rotating plate 462 is connected to the rotating mechanism 45. The rotating plate 462 is provided with a sliding sleeve 4622 sleeved on the outside of the lever 4611 and slidably connected to the lever 4611. A first elastic element 4623 is also provided between the sliding sleeve 4622 and the lever 4611.

[0042] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown; when the first water accumulation chamber 441 and the second water accumulation chamber 442 move toward the opening 21, the elastic force of the first elastic member 4623 will cause the push plate 461 to extend toward the rotating mechanism 45, thereby facilitating the push plate 461 and the rotating mechanism 45 to abut against the abutment plate 422. Afterwards, when the first water accumulation chamber 441 and the second water accumulation chamber 442 continue to move, the push plate 461 on the first water accumulation chamber 441 will overcome the elastic force of the first elastic member 4623 and move toward the sealing mechanism 41. The first elastic member 4623 in the second water accumulation chamber 442 is still in the state of stretching the push plate 461 toward the rotating mechanism 45.

[0043] The rotating mechanism 45 includes a rotating block 451, a drive wheel 452, a ring sleeve 453, a first gear 454, a second gear 455, a first bevel gear 456, a second bevel gear 457, and a first motor 458. The rotating block 451 is used to connect with the rotating plate 462. The ring sleeve 453 is sleeved between the two rotating blocks 451 and rotatably connected to the two rotating blocks 451. A sealed cavity is formed between the ring sleeve 453 and the two rotating blocks 451. The drive wheel 452 is disposed in the cavity and connected to the two rotating blocks 451. The gears are fixedly connected. The first gear 454 is mounted on the ring 453 and meshes with the drive wheel 452. The second gear 455 is mounted on the ring 453 and meshes with the first gear 454. The first bevel gear 456 is coaxially mounted with the second gear 455. The first bevel gear 456 and the transmission wheel 332, which is rotatably connected to the rotating shaft 331, are connected to the second gear 455. The second bevel gear 457 is mounted on the ring 453 and meshes with the first bevel gear 456. The second bevel gear 457 is connected to the first motor 458.

[0044] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the operator drives the first bevel gear 456 to rotate via the first motor 458, causing the second bevel gear 457, which meshes with the first bevel gear 456, to rotate. This causes the second gear 455, the first gear 454, and the drive wheel 452 to rotate sequentially. The drive wheel 452 then drives two rotating blocks 451 to rotate relative to the ring sleeve 453. This causes the rotating plate 462 to rotate the lever 4611, the sliding sleeve 4622, and the push plate 461. Consequently, the lever 4611 and the sliding sleeve 4622 move the first and second water accumulation chambers 441 and 442, thereby preventing the inlet 421 from being blocked by plant leaves and accelerating the mixing of microorganisms and sewage. It should be noted that both the lever 4611 and the sliding sleeve 4622 are inclined. At the same time, the ring sleeve 453 is provided with an upwardly extending protruding shell for fitting around the outside of the first motor 458. The cover 42 is provided with a sliding groove for sliding connection with the protruding shell. The sliding groove facilitates the sliding of the protruding shell and can also limit the ring sleeve 453 to prevent the ring sleeve 453 from rotating synchronously with the rotating block 451.

[0045] The transmission pipe 2 is provided with a guide groove 22, and the rotating block 451 is provided with a sliding block 4511 that is slidably connected to the guide groove 22. The rotating block 451 and the sliding block 4511 are rotatably connected. The rotating block 451 and the sliding block 4511 are respectively provided with a sealing groove 4512 and a sealing ring 4513.

[0046] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown; it should be noted that a sliding block 4511 is also provided on the drive block 44. The drive block 44 and the rotating block 451 move stably and orderly through the slide groove and the sliding block 4511 respectively. During this process, since the rotating block 451 needs to rotate, the sliding block 4511 needs to be rotatably connected to the rotating block 451. The sealing groove 4512 and the sealing ring 4513 provided on the rotating block 451 and the sliding block 4511 are to enhance the sealing effect between the rotating block 451 and the sliding block 4511.

[0047] Two flow extension mechanisms 3 are provided and correspond to two openings 21 respectively. The input end of the flow extension mechanism 3 is connected to the opening 21. The flow extension mechanism 3 includes a first guide plate 31 and a second guide plate 32. Multiple first guide plates 31 and second guide plates 32 are provided. The first guide plates 31 and second guide plates 32 are arranged sequentially inside the transmission pipe 2. A first drainage hole 311 is provided at the top of the first guide plate 31, and a second drainage hole 321 is provided at the bottom of the second guide plate 32. A chamber is formed between the first guide plate 31 and the second guide plate 32. A flow extension channel for extending the flow distance of sewage is formed between the first drainage hole 311, the chamber, and the second drainage hole 321.

[0048] like Figures 3 to 8 As shown, the operator delivers wastewater into the transmission pipe 2 through the infusion pipe 1. Then, the microorganisms are transferred from the opening 21 to the input end of the flow extension mechanism 3 through the sealing mechanism 41 and the feeding component 4, so that the wastewater and microorganisms move together. At this time, the mixture of wastewater and microorganisms will come into contact with the first guide plate 31 and the second guide plate 32 and be guided by them, so that the mixture moves in the flow extension channel in the order of the first drainage hole 311-chamber-second drainage hole 321. This process prolongs the movement distance of the mixture, thereby increasing the contact time between wastewater and microorganisms, which makes it easier for microorganisms to purify wastewater.

[0049] The flow extension mechanism 3 also includes a rotating wheel 33 and a second motor 34. Multiple rotating wheels 33 are arranged sequentially inside the chamber. The rotating wheels 33 are rotatably connected to the chamber. The rotating wheels 33 are used to collect and conduct sewage passing through the chamber. Both ends of the rotating wheels 33 are provided with a rotating shaft 331 and a transmission wheel 332 rotatably connected to the rotating shaft 331. Two adjacent rotating wheels 33 are connected through the transmission wheel 332. The second motor 34 is connected to only one transmission wheel 332.

[0050] like Figures 3 to 8 As shown; firstly, the second motor 34 drives the transmission wheel 332 to rotate, so that multiple rotating wheels 33 rotate synchronously through the transmission wheel 332, so that the rotating wheels 33 pick up the sewage and microorganisms in the chamber, enhance the mixing effect of the two, and at the same time, the rotating wheels 33 can control the time for sewage and microorganisms to pass through the extension mechanism 3.

[0051] Two openings 21 are respectively located at the input end and the middle part of the transmission pipe 2. Each opening 21 has a groove 211. The sealing mechanism 41 includes a sealing plate 411, a transmission plate 412, a transmission rod 413, and a second elastic element 414. The sealing plate 411 is slidably disposed on the opening 21. The sealing plate 411 has a protruding plate 4111 for inserting into the groove 211. The outer surface of the protruding plate 4111 is made of a flexible material. The protruding plate 4111 and the groove 211 are press-fitted together, close to the transmission pipe. The sealing plate 411 at the input end can directly contact the drive block 44. The sealing plate 411 near the middle of the transmission pipe 2 is connected to the transmission rod 413 and the transmission plate 412. The transmission rod 413 can contact the drive block 44. The second elastic element 414 is used to connect the transmission pipe 2 and the sealing plate 411. The second elastic element 414 is used to connect the transmission pipe 2 and the transmission plate 412. The transmission plate 412, the transmission rod 413, the first elastic element 4623 and the second elastic element 414 are all made of non-magnetic materials.

[0052] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown; when the driving block 44 moves a certain distance, it will contact the sealing plate 411 or the transmission plate 412, causing the sealing plate 411 or the transmission plate 412 to move across the opening 21 against the elastic force of the second elastic element 414. This causes the protrusion 4111 on the sealing plate 411 to separate from the groove 211, thereby opening the opening 21. This allows the first water accumulation chamber 441 or the second water accumulation chamber 442 to separate from the sealing plate 411 through the opening 21. When the driving block 44 resets, the sealing plate 411 will move along with the driving block 44 under the elastic force of the second elastic element 414, causing the protrusion 4111 to seal the groove 211, thus closing the opening 21. The outer surface of the protrusion 4111 is made of a flexible material to facilitate the insertion of the protrusion 4111 into the groove 211. The transmission plate 412, transmission rod 413, first elastic element 4623, and second elastic element 414 are all made of non-magnetic materials to prevent them from being affected by the magnetic force of electromagnet 43, thus affecting the sealing effect on opening 21. It should be noted that since the mixture of sewage and microorganisms needs to pass through the guide mechanism, opening 21 needs to be located in front of the flow-extending mechanism 3. However, since the two flow-extending mechanisms 3 are located at opposite ends of the transmission pipe 2, to save space, one of the openings 21 needs to be located in the middle of the transmission pipe 2. However, since the two drive blocks 44 need to move the same distance when in contact with the sealing mechanism 41, the sealing plate 411 located in the middle of the transmission pipe 2 needs to be driven by the transmission plate 412 and transmission rod 413.

[0053] A stirring and guiding mechanism 5 is also provided between the two flow extension mechanisms 3. The stirring and guiding mechanism 5 includes a guiding ring plate 51, a guide cylinder 52, a stirring rod 53, and a supporting ring plate 54. The guiding ring plate 51 is provided between the flow extension mechanism 3 and the opening 21 located in the middle of the transmission pipe 2. The guiding ring plate 51 is provided with a through hole 511. The guide cylinder 52 is used to separate the through hole 511 and the opening 21. The stirring rod 53 is provided between the guide cylinders 52. The supporting ring plate 54 is provided between the guide cylinders 52 and the transmission pipe 2.

[0054] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown; the continuous flow reactor enhances the mixing effect of wastewater and microorganisms through the stirring rod 53, thereby facilitating the degradation of wastewater by microorganisms. Microorganisms passing through the opening 21 in the middle of the transmission pipe 2 are transported along the channel formed between the outer wall of the guide tube 52 and the inner wall of the transmission pipe 2 until they pass through the stirring rod 53 inside the guide tube and are mixed with the wastewater. This prevents the microorganisms passing through the opening 21 in the middle of the transmission pipe 2 from being directly transferred without mixing with the wastewater, which would affect the mixing effect between microorganisms and wastewater. The mixed wastewater and microorganisms will exit through the through hole 511, the flow extension mechanism 3, and the output end of the transmission pipe 2.

[0055] A flow limiting mechanism 6 is provided between the input end of the transmission pipe 2 and the opening 21 located at the input end of the transmission pipe 2. The flow limiting mechanism 6 includes a flow limiting bracket 61 and a moving block 62. The flow limiting bracket 61 is provided with a transmission hole 611. The moving block 62 is connected to the blocking plate 411. The moving block 62 is provided with a blocking block 621 for blocking the transmission port. The blocking block 621 is provided with multiple evenly distributed flow limiting channels 6211.

[0056] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown; when the blocking plate 411 drives the moving block 62 to slide, the blocking block 621 will separate from the transmission hole 611, facilitating the transmission of sewage. The sewage and microorganisms will first pass through a flow extension mechanism 3 for preliminary degradation. When the blocking plate 411 separates from the moving block 62, the blocking block 621 will block the transmission port, and the sewage can only be transmitted through the flow restriction channel 6211, reducing the amount of sewage transmitted. During this process, the opening 21 connected to the second water accumulation chamber 442 will open, further introducing microorganisms, increasing the content of microorganisms, increasing the contact area between sewage and microorganisms, and further enhancing the degradation effect of sewage and microorganisms through another flow extension mechanism 3. At the same time, it can also prevent the stirring and guiding mechanism 5 from moving towards the input end of the transmission pipe 2 and not entering the guide pipe.
