Preferably, the number of ring bodies in each connection ring is consistent and corresponds to the number of ring bodies in the connection ring above or below. The number of connection ropes is equal to the number of ring bodies in each connection ring. The telescopic cover can be retracted by pulling the connection ropes. In general, the top of the telescopic cover is connected to the support and installation assembly 10 or the connection structure 30.

[0088] As shown in Figure 1 , Figure 4 , Figure 8 , in order to facilitate the diversion of sewage, the difference from the above-mentioned embodiments is that the middle part of the dispersing structure 201 is provided with a sewage diversion assembly 40 for diverting the sewage in the dispersing structure 201.

[0089] The sewage diversion assembly 40 includes a collection part 400 and a sewage diversion pipeline 401. The collection part 400 is arranged in the middle part of the dispersing structure 201 and is used for collecting sewage. The sewage diversion pipeline 401 is arranged on one side of the collection part 400 and is used for discharging the sewage in the collection part 400.

[0090] As shown in Figure 9 , the collection part 400 includes a movable collection plate 402, a movable connecting plate 403, a fixed collection plate 404, a collecting pipe 405, a first driving member 406 and a second driving member 407. The fixed collection plate 404 is arranged in the middle part of the dispersing structure 201 and is fixedly connected to one end of the dispersing structure 201. The movable connecting plate 403 is arranged on the fixed collection plate 404 and is slidably connected to the fixed collection plate 404. The movable collection plate 402 is arranged on the movable connecting plate 403 and is slidably connected to the movable connecting plate 403. The collecting pipe 405 is arranged on one side of the movable collection plate 402, the movable connecting plate 403 and the fixed collection plate 404 and is fixedly connected to the movable collection plate 402, the movable connecting plate 403 and the fixed collection plate 404. The collecting pipe 405 is arranged in the installation cavity between the water retaining cover 206 and the dispersing structure 201. The bottom of the collecting pipe 405 is provided with a water outlet 408. One end of the sewage diversion pipeline 401 is connected to the water outlet 408, and the other end of the sewage diversion pipeline 401 extends out of the installation cavity.

[0091] The first driving member 406 is arranged on one side of the scattering structure 201, and is used to drive the movable collecting plate 402 and the movable connecting plate 403 to retract. The second driving member 407 is arranged on the other side of the scattering structure 201, and is used to drive the movable collecting plate 402 and the movable connecting plate 403 to extend.

[0092] When in use, the setting of the movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404 can realize partial or complete diversion of domestic sewage. The sewage diversion process is realized by gravity. By setting the first driving member 406 and the second driving member 407, the movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404 can be adjusted, thereby adjusting the diversion amount of sewage.

[0093] In one embodiment, the fixed collecting plate 404 is fixedly connected to one end of the middle portion of the second mounting member 303 , and the movable collecting plate 402 and the movable connecting plate 403 are slidably fitted with the second mounting member 303 .

[0094] In one embodiment, the movable collecting plate 402, the movable connecting plate 403, and the fixed collecting plate 404 are arranged in a coordinated manner. When the movable collecting plate 402, the movable connecting plate 403, and the fixed collecting plate 404 overlap, one-third of the sewage (such as domestic sewage) can be collected and diverted. When the movable collecting plate 402 is pulled out, two-thirds of the sewage can be collected and diverted. When both the movable collecting plate 402 and the movable connecting plate 403 are pulled out, all of the sewage can be collected and diverted. That is, by pulling out the movable collecting plate 402 and / or the movable connecting plate 403, sewage can be diverted within a collection range of 1 / 3-1.

[0095] like Figure 9 As shown, in order to facilitate the relative sliding and limiting between the movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that a first limiting groove 409 is provided on both sides of the fixed collecting plate 404, and a first limiting block 410 is provided on both sides of the movable connecting plate 403 to cooperate with the first limiting groove 409. The first limiting block 410 is located in the first limiting groove 409 and is slidably connected to the first limiting groove 409. A second limiting groove 411 is provided on both sides of the movable connecting plate 403, and a second limiting block 412 is provided on both sides of the movable collecting plate 402 to cooperate with the second limiting groove 411. The second limiting block 412 is located in the second limiting groove 411 and is slidably connected to the second limiting groove 411.

[0096] The first limiting groove 409 and the first limiting block 410 are arranged, so that the sliding between the movable connecting plate 403 and the fixed collecting plate 404 can be limited, and the second limiting groove 411 and the second limiting block 412 are arranged, so that the sliding between the movable collecting plate 402 and the movable connecting plate 403 can be limited, thereby facilitating the stretching expansion of the movable connecting plate 403 and the movable collecting plate 402.

[0097] In one embodiment, during the stretching expansion, only when the second limiting block 412 on the movable collecting plate 402 slides to one end of the second limiting groove 411 on the movable connecting plate 403, the sliding between the movable connecting plate 403 and the fixed collecting plate 404 can be continued, until the first limiting block 410 slides to one end of the first limiting groove 409, and the movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404 are completely unfolded.

[0098] As shown in Figure 10 , in order to facilitate the relative sliding between the movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404, the first driving member 406 includes a first pull rope and a first guide rod, and the first guide rod is fixedly arranged on one side of the scattering structure 201. One end of the first pull rope is connected to one end (such as the left end of the movable collecting plate 402) of the movable collecting plate 402, and the other end of the first pull rope is wound around the first guide rod and extends to the outside of the mounting cavity through the mounting cavity. The end portion of the first pull rope extending to the outside of the mounting cavity is provided with a first pull ring.

[0099] The second driving member 407 includes a second pull rope and a second guide rod, and the second guide rod is fixedly arranged on the other side of the scattering structure 201. One end of the second pull rope is connected to one end (such as the right end of the movable collecting plate 402) of the movable collecting plate 402, and the other end of the second pull rope is wound around the second guide rod and extends to the outside of the mounting cavity. The end portion of the second pull rope extending to the outside of the mounting cavity is provided with a second pull ring.

[0100] The first pull ring can be used to pull the first pull rope, so as to drive the movable collecting plate 402 and the movable connecting plate 403 to retract, and the second pull ring can be used to pull the second pull rope, so as to drive the movable collecting plate 402 and the movable connecting plate 403 to extend.

[0101] As shown in Figure 1 , Figure 11 , Figure 14 In order to solve the problem that the current domestic sewage treatment system needs to build an aeration tank and an aeration device, resulting in high construction cost and subsequent maintenance cost, the utility model provides a sewage treatment system, which comprises the above-mentioned non-powered sewage aerobic device and further comprises:

[0102] The organic matter decomposition tank 50 is arranged on one side of the support and installation assembly 10. The organic matter decomposition tank 50 can realize microbial decomposition of organic matter in sewage. A partition 500 is provided in the organic matter decomposition tank 50. The partition 500 divides the organic matter decomposition tank 50 into an anaerobic unit 501 and an anoxic unit 502. A sewage overflow pipe 503 is provided at the upper end of the partition 500. One end of the sewage overflow pipe 503 is located in the anaerobic unit 501, and the other end is located in the anoxic unit 502. The sewage overflow pipe 503 is located at one end of the anoxic unit 502 and extends to the bottom of the anoxic unit 502.

[0103] The anaerobic unit 501 is a closed cavity for anaerobic microorganisms to decompose organic matter, and the anoxic unit 502 is an open cavity for aerobic and facultative microorganisms to decompose organic matter.

[0104] The sedimentation tank 60 is arranged below the breaking-up structure 201. The sewage passing through the breaking-up structure 201 can fall into the sedimentation tank 60 to complete sedimentation and stratification. The sewage after sedimentation and stratification can form treated water at the upper layer and sludge at the lower layer.

[0105] The anoxic unit 502 of the organic matter decomposition tank 50 is provided with a sewage lifting component 504 for pumping the sewage in the anoxic unit 502 into the processor 200, and the bottom of the sedimentation tank 60 is provided with a sludge return component 600 for returning the lower layer of sludge produced after the sewage sedimentation and stratification in the sedimentation tank 60 to the anoxic unit 502.

[0106] It should be noted that, in this embodiment, the position of the sedimentation tank 60 needs to be relatively higher than the position of the organic decomposition tank 50, so that there is a height difference between the sedimentation tank 60 and the organic decomposition tank 50, so that the sludge can flow back to the bottom of the anoxic unit 502 of the organic decomposition tank 50 through the sludge return assembly 600 under the action of gravity.

[0107] Furthermore, preferably, a filler is provided in the sedimentation tank 60. The filler may be a plurality of bag-type fillers containing filter materials such as graphite carbon, quartz sand, and ceramsite volcanic rock. The provision of a plurality of bag-type fillers allows for rapid separation of the upper layer of treated water (e.g., qualified water, i.e., water that meets discharge requirements) and the lower layer of sludge.

[0108] like Figure 12 As shown, in one embodiment, the organic matter decomposition tank 50 can be a rectangular organic matter decomposition tank 50, and the partition 500 can be a partition plate, which is arranged in the rectangular organic matter decomposition tank 50 to divide the rectangular organic matter decomposition tank 50 into a rectangular anaerobic unit 501 and an anoxic unit 502, and the sewage overflow pipe 503 is arranged at the upper end of the partition plate.

[0109] Among them, a water inlet 505 and a first sludge discharge outlet 506 are provided on one side of the anaerobic unit 501. The water inlet 505 is set at the upper end of the anaerobic unit 501, and the first sludge discharge outlet 506 is set at the lower end of the anaerobic unit 501. A second sludge discharge outlet 507 is provided on one side of the anoxic unit 502, and the second sludge discharge outlet 507 is set at the lower end of the anoxic unit 502.

[0110] During use, domestic sewage that has been coarsely filtered through the screen can be injected into the anaerobic unit 501 through the water inlet 505. The domestic sewage in the anaerobic unit 501 can enter the anoxic unit 502 through the sewage overflow pipe 503. The setting of the first sludge discharge outlet 506 and the second sludge discharge outlet 507 can facilitate the discharge of sludge in the anaerobic unit 501 and the anoxic unit 502 when cleaning the organic matter decomposition tank 50.

[0111] like Figure 13 As shown, in another embodiment, the organic matter decomposition tank 50 can be a hemispherical organic matter decomposition tank 50 with a flat bottom, and the partition 500 can be a hollow cylindrical partition tube. The partition tube is arranged in the hemispherical organic matter decomposition tank 50, and the bottom is connected to the plane of the organic matter decomposition tank 50. The partition tube divides the organic matter decomposition tank 50 into an anaerobic unit 501 located inside the partition tube and an anoxic unit 502 located outside the partition tube, and a sewage overflow pipe 503 is arranged at the upper end of the partition tube.

[0112] A water inlet 505 is provided on the top of the separation pipe, and a first sludge discharge outlet 506 coordinated with the anaerobic unit 501 and a second sludge discharge outlet 507 coordinated with the anoxic unit 502 are provided on the bottom plane of the organic matter decomposition tank 50 .

[0113] The above two embodiments can be selected according to actual installation requirements, and both can effectively decompose organic matter.

[0114] like Figure 8 As shown, in order to facilitate the transportation of sewage to the processor 200 for outflow or spraying, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that the sewage lifting component 504 includes a submersible sewage pump 508 arranged in the anoxic unit 502 of the organic matter decomposition tank 50 and a sewage conveying pipe 509 for connecting the submersible sewage pump 508 and the processor 200. The sewage in the anoxic unit 502 of the organic matter decomposition tank 50 can be transported to the processor 200 for spraying through the pump (such as the submersible sewage pump 508) and the sewage conveying pipe 509.

[0115] The domestic sewage can be pumped from the anoxic unit 502 into the processor 200 to flow out or be sprayed out by the submersible sewage pump 508. The sewage delivery pipe 509 can be a hose in the prior art, such as a PE hose.

[0116] like Figure 15As shown, in order to facilitate the adjustment of the position of the submersible sewage pump 508 and thus effectively pump out the sewage in the anoxic unit 502, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that a lifting assembly 510 is provided at the organic matter decomposition tank 50. The lifting assembly 510 includes a sliding mounting seat 511, a fixed mounting arm 512 and a driving member 513. The fixed mounting arm 512 is provided in the anoxic unit 502 of the organic matter decomposition tank 50. The sliding mounting seat 511 is slidably provided on the fixed mounting arm 512. The submersible sewage pump 508 is provided on the sliding mounting seat 511. The driving member 513 is provided on one side of the organic matter decomposition tank 50 for driving the sliding mounting seat 511 to slide on the fixed mounting arm 512.

[0117] In the present invention, the driving member 513 can drive the sliding mounting seat 511 to move, thereby enabling the submersible sewage pump 508 to move along the fixed mounting arm 512 , thereby enabling the height of the submersible sewage pump 508 to be adjusted within the anoxic unit 502 .

[0118] In one embodiment, the driving member 513 includes a guide pulley 514, a lifting rope 515 and a winch 516. A pulley mounting seat 517 for mounting the guide pulley 514 is provided on the fixed mounting arm 512. The guide pulley 514 is rotatably set on the pulley mounting seat 517. The winch 516 is set on one side of the organic matter decomposition tank 50. One end of the lifting rope 515 is connected to the winch 516 and can be wound or released through the winch 516. The other end bypasses the guide pulley 514 and is connected to the sliding mounting seat 511.

[0119] When in use, the hoisting rope 515 can be wound up or released by the hoisting machine 516, thereby realizing the movement of the sliding mounting seat 511. Wherein, the guide pulley 514 plays a guiding role.

[0120] like Figure 14 As shown, in order to facilitate the collection and return of sludge in the sedimentation tank 60, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that the sludge return component 600 includes a sludge three-way valve 601 for controlling the discharge of sludge and a sludge return pipe 602 for connecting the sludge three-way valve 601 and the anoxic unit 502 of the organic matter decomposition tank 50. A sludge outflow outlet 603 for sludge outflow is provided at the bottom of the sedimentation tank 60. One end of the sludge three-way valve 601 is connected to the sludge outflow outlet 603. One end of the sludge return pipe 602 is connected to one end of the sludge three-way valve 601, and the other end extends to the anoxic unit 502 of the organic matter decomposition tank 50 (or the inner bottom of the anoxic unit 502). One end of the sludge three-way valve 601 can be connected to an external discharge pipe.

[0121] When the sludge concentration in the anoxic unit 502 is insufficient, that is, the bacterial concentration in the anoxic unit 502 is insufficient, the sludge in the sedimentation tank 60 can be returned to the anoxic unit 502 through the sludge outflow outlet 603, the sludge three-way valve 601 and the sludge conveying pipeline.

[0122] When the sludge concentration in the anoxic unit 502 reaches the standard, it is discharged to the sludge collection point through the sludge outflow outlet 603, the sludge three-way valve 601 and the discharge pipe to complete the collection. The sludge return process and the sludge discharge process can be achieved by gravity.

[0123] In addition, in order to discharge the qualified water in the upper layer of the sedimentation tank 60, in one embodiment, a qualified water overflow pipe 604 is provided at the upper end of the sedimentation tank 60, and the qualified water overflow pipe 604 can be connected to an external pipeline to the wetland.

[0124] like Figure 8 As shown, in order to facilitate the return of aerated / aerobic sewage from the dispersion structure 201 to the anoxic unit 502, thereby bringing oxygen to the anoxic unit 502, this embodiment differs from the above-mentioned embodiment in that the sewage diversion pipe 401 extends to the end outside the installation cavity and extends to the anoxic unit 502 (or the bottom of the anoxic unit 502).

[0125] It should be noted that, in this embodiment, the position of the organic matter decomposition tank 50 needs to be lower than the position of the scattering structure 201, so that there is a height difference between the scattering structure 201 and the organic matter decomposition tank 50, so that the sewage in the scattering structure 201 can flow back to the bottom of the anoxic unit 502 of the organic matter decomposition tank 50 through the sewage diversion component 40 under the action of gravity, thereby replenishing oxygen for the anoxic unit 502.

[0126] In one embodiment, when the present invention is in use, the sewage that has been coarsely filtered through the grid is first injected into the anaerobic unit 501 in the organic matter decomposition tank 50 through the water inlet 505, and part of the organic matter in the sewage is decomposed by the microorganisms in the anaerobic unit 501. Then, the sewage in the anaerobic unit 501 enters the anoxic unit 502 through the sewage overflow pipe 503, and part of the organic matter in the sewage is decomposed by the microorganisms in the anoxic unit 502.

[0127] The sewage in the anoxic unit 502 can be pumped into the processor 200 and sprayed out by the submersible sewage pump 508. The sewage flowing out or sprayed out of the processor 200 passes through the dispersion plate 202 in the dispersion structure 201 step by step under the action of gravity, and is thereby broken up into a number of water molecules and water droplets under the combined action of the dispersion plate 202 and gravity, so that the sewage can fully contact with oxygen and complete unpowered aeration / aerobic.

[0128] When the sewage or water droplets in the dispersed structure 201 pass through the sewage shunt assembly 40, part of the sewage that has passed through the aeration / oxygen process can flow back to the anoxic unit 502 through the movable collection plate 402, the movable connecting plate 403, the fixed collection plate 404, the collecting pipe 405 and the sewage shunt pipe 401 to supplement oxygen for the anoxic unit 502, and the other part of the sewage that has passed through the aeration / oxygen process continues to fall, thereby continuing aeration / oxygen, until falling into the sedimentation tank 60.

[0129] The sewage in the sedimentation tank 60 can be quickly precipitated and stratified into upper layer standard water and lower layer sludge under the action of the bagged filler, wherein the standard water can be transported to the wetland for discharge through the standard water overflow pipe 604 and the external pipeline, and the sludge can be flowed back to the anoxic unit 502 through the sludge outlet 603, the sludge three-way valve 601 and the sludge reflux pipe 602, or discharged and collected through the sludge outlet 603, the sludge three-way valve 601 and the discharge pipe.

[0130] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.

One end of the sewage overflow pipe (503) is located in the anaerobic unit (501), and the other end is located in the anoxic unit (502). One end of the sewage overflow pipe (503) is located in the anoxic unit (502) and extends to the bottom of the anoxic unit (502). The sewage diversion pipe (401) extends to the end of one end outside the installation cavity and extends to the anoxic unit (502). The anaerobic unit (501) is a closed cavity for anaerobic microorganisms to decompose organic matter, and the anoxic unit (502) is an open cavity for aerobic and facultative microorganisms to decompose organic matter; The sedimentation tank (60) is arranged below the dispersing structure (201). The sewage passing through the dispersing structure (201) can fall into the sedimentation tank (60) to complete sedimentation and stratification. The sewage after sedimentation and stratification can form treated water at the upper layer and sludge at the lower layer. A sewage lifting assembly (504) for pumping sewage in the anoxic unit (502) into the processor (200) is provided in the anoxic unit (502) of the organic matter decomposition tank (50), and a sludge return assembly (600) for returning the lower layer of sludge generated after sewage sedimentation and stratification in the sedimentation tank (60) to the anoxic unit (502) is provided at the bottom of the sedimentation tank (60).
