[0002] Domestic sewage is wastewater discharged from residents' daily lives, mainly from residential buildings and public buildings, such as residences, offices, schools, hospitals, shops, public places and toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly large impurities and organic matter. The organic matter in domestic sewage is extremely unstable and easily decomposes to produce odor. Therefore, domestic sewage must be treated before discharge.

[0003] At present, the treatment of domestic sewage generally removes larger impurities through screens, then decomposes some of the organic matter through anaerobic microorganisms, and then decomposes the remaining organic matter through aerobic and facultative microorganisms. Among them, anaerobic microorganisms generally convert organic matter into organic acids in an anaerobic environment, and then use methanogens to decompose organic acids into harmless gases such as methane, carbon dioxide and hydrogen. Aerobic and facultative microorganisms decompose organic matter under aerobic conditions after aeration. In the current sewage treatment system, domestic sewage is aerated mainly through mechanical aeration, which usually requires the establishment of aeration tanks and aeration equipment. This leads to the current domestic sewage treatment system has high construction costs and subsequent maintenance costs.

[0057] The sewage treatment assembly 20 includes a processor 200 and a dispersing structure 201. The processor 200 is used to discharge water. The dispersing structure 201 includes a plurality of dispersing plates 202. The dispersing plates 202 are arranged below the processor 200. When the sewage flowing out or sprayed from the processor 200 falls on the dispersing plates 202, the sewage is dispersed into a plurality of water droplets.

[0058] The dispersion plate 202 includes a baffle plate provided with a plurality of filter holes, the baffle plate is used to disperse the sewage and is used for installation; a sewage treatment space 203 is provided above and / or below the baffle plate, and the sewage or water droplets are treated in the sewage treatment space 203; the baffle plate includes a treatment area 204 and an installation area 205, the treatment area 204 is placed in the installation area 205, the treatment area 204 is provided with filter holes, and the installation area 205 is provided with an installation structure.

[0059] The present invention adopts a basic structure as a supporting layer, and a supporting installation component 10 is arranged on the supporting layer, which includes a supporting frame 100, which is used as a supporting device for the sewage treatment component 20 and can play a good supporting role for the sewage treatment component 20; it should be noted that the basic structure can be a stable building structure such as the ground and a platform.

[0060] Secondly, the present invention also provides a connection structure 30 between the sewage treatment component 20 and the support and installation component 10, such as Figures 1 to 5 As shown, the connection structure 30 is not limited to an external connector, that is, an external connector; it can also be connected in various ways through an assembly structure arranged on the sewage treatment component 20 and the support and installation component 10, which is convenient for construction according to the actual site; it should be noted that the assembly structure includes a structure 1 placed on the sewage treatment component 20 and a structure 2 placed on the support and installation component 10, such as Figure 6 As shown, the structure 1 and the structure 2 can adopt the common mortise and tenon structure, which is convenient for assembly and construction. The structure 1 and the structure 2 can also adopt the common clamping structure.

[0061] In addition, on the basis of the connection structure 30, the present invention also designs the structure of the sewage treatment component 20, which includes a processor 200, i.e., a device for flowing out or spraying out sewage, and a scattering structure 201, and the spatial position relationship thereof is that the processor 200 is on the top and the scattering structure 201 is on the bottom, so that the sewage can be scattered by the dispersion plate 202 in the scattering structure 201 without power, so as to achieve the aeration / aerobic effect. In the actual construction process, the engineering personnel can set the dispersion plate 202 of the scattering structure 201 to at least two layers, that is, the sewage can be aerated / aerophilic at least twice after coming out of the processor 200, and the sewage is gradually scattered into water droplets by the dispersion plate 202 and aerated / aerobic, which can further enhance the aeration / aerobic effect.

[0062] In order to achieve the effect of enhancing aeration / aerobicity, the present invention also provides a sewage treatment space 203 above and / or below the baffle. The purpose of leaving enough space is to ensure that the sewage or water droplets can fully react with the air to avoid directly entering the confined space or pipeline and affecting the aeration / aerobicity effect.

The area division of the baffle is clear, which is convenient for operation.

[0063] The present invention solves the problem that the current domestic sewage treatment system needs to build an aeration tank and aeration equipment, resulting in high construction costs and subsequent maintenance costs.

[0064] In addition, it should be noted that aeration in the present invention refers to the process in which sewage falls on the dispersion plate 202 and is broken into a number of water droplets by the dispersion plate 202. After aeration, the sewage can contact more air; aerobic refers to the process in which sewage or water droplets (in the sewage treatment space 203) contact air (or oxygen-containing air). Unpowered means that it can be completed by gravity without the need for additional power-providing equipment. The processor 200 can use a water distributor in the prior art, such as a water distribution tray or a water distribution nozzle.

[0065] It should be noted that in the above embodiment, the height range of the sewage treatment space 203 is 20-30 cm, that is, the distance between two adjacent dispersion plates 202 is 20-30 cm. The height range of the sewage treatment space 203 is controlled at 20-30 cm, which can allow the sewage to have enough distance for aeration, and can also effectively avoid the problem of sewage splashing far away.

[0066] The mounting structure can adopt a conventional frame structure. In order to facilitate water retaining, a plurality of water retaining side plates inclined outwards can also be arranged on the top of the mounting structure, and the plurality of water retaining side plates can form a funnel-shaped water retaining portion, thereby reducing sewage splashing outwards.

[0074] During installation, the hanging ring 301 on the processor 200 can be hung on the hook 300 on the support frame 100.

[0085] One end of the driving rope 213 connected to the fourth cover body 212 is two ropes, and the two ropes are fixedly connected to the two sides of the fourth cover body 212 respectively.

[0086] The present invention can realize the expansion and retraction of the telescopic cover through the driving rope 213 and the pulley steering group 214. This structure is more suitable for use in domestic sewage treatment systems below the market town, such as domestic sewage treatment systems with a treatment capacity of less than 500 cubic meters.

[0087] In another embodiment, the telescopic cover is a canvas cover, and the two sides of the canvas cover are connected to form a cylinder, and the two ends of the cylinder are open. A plurality of connecting rings are arranged on the canvas cover, and each connecting ring includes a plurality of ring bodies. The connecting rope passes through the plurality of connecting rings from top to bottom and is fixed to the bottom of the canvas cover. Preferably, the number of ring bodies arranged on each connecting ring is consistent and corresponds to each other. The number of connecting ropes is the same as the number of ring bodies on each connecting ring. The telescopic cover can be retracted by pulling the connecting rope. Generally, the top of the telescopic cover is connected to the support mounting assembly 10 or the connecting structure 30.

[0088] like Figure 1 , Figure 4 , Figure 8 As shown, in order to facilitate sewage diversion, the difference from the above embodiment is that a sewage diversion component 40 for diverting sewage in the diverting structure 201 is provided in the middle of the diverting structure 201 .

[0089] The sewage diversion component 40 includes a collecting part 400 and a sewage diversion pipe 401. The collecting part 400 is arranged in the middle of the scattered structure 201 for collecting sewage. The sewage diversion pipe 401 is arranged on one side of the collecting part 400 for discharging sewage in the collecting part 400.

[0090] like Fig. 9 As shown, the collecting part 400 includes a movable collecting plate 402, a movable connecting plate 403, a fixed collecting plate 404, a collecting pipe 405, a first driving member 406 and a second driving member 407. The fixed collecting plate 404 is tiltedly arranged in the middle of the scattering structure 201 and is fixedly connected to one end of the scattering structure 201. The movable connecting plate 403 is arranged on the fixed collecting plate 404 and is slidably connected to the fixed collecting plate 404. The movable collecting plate 402 is arranged on the movable connecting plate 403 and is slidably connected to the movable collecting plate 404. The connecting plate 403 is slidably connected, and the collecting pipe 405 is arranged on one side of the movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404, and is fixedly connected to the movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404. The collecting pipe 405 is located in the installation cavity between the water retaining cover 206 and the scattering structure 201. A water outlet 408 is provided at the bottom of the collecting pipe 405. One end of the sewage diversion pipe 401 is connected to the water outlet 408, and the other end extends to the outside 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 full diversion of domestic sewage. The sewage diversion process is realized by gravity. The movable collecting plate 402, the movable connecting plate 403 and the fixed collecting plate 404 can be adjusted by setting the first driving member 406 and the second driving member 407, 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 matched 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 cooperation. 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 for diversion. When the movable collecting plate 402 is pulled out, two-thirds of the sewage can be collected for diversion. When both the movable collecting plate 402 and the movable connecting plate 403 are pulled out, all the sewage can be collected for diversion. That is, by pulling out the movable collecting plate 402 and / or the movable connecting plate 403, the sewage can be diverted within a collection range of 1 / 3-1.

[0095] like Fig. 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, the present embodiment is improved on the basis of the above embodiment, and the difference from the above embodiment lies in that first limiting grooves 409 are provided on both sides of the fixed collecting plate 404, first limiting blocks 410 are provided on both sides of the movable connecting plate 403 and are matched with the first limiting grooves 409, the first limiting blocks 410 are located in the first limiting grooves 409 and are slidably connected to the first limiting grooves 409, second limiting grooves 411 are provided on both sides of the movable connecting plate 403, second limiting blocks 412 are provided on both sides of the movable collecting plate 402 and are matched with the second limiting grooves 411, the second limiting blocks 412 are located in the second limiting grooves 411 and are slidably connected to the second limiting grooves 411.

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

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

[0098] like Fig.10 As shown, in order to facilitate the relative sliding between the movable collection plate 402, the movable connecting plate 403 and the fixed collection plate 404, this embodiment is improved on the basis of the above embodiment, and the first driving member 406 includes a first pull rope and a first guide rod, 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 of the movable collection plate 402 (for example, the left end of the movable collection plate 402), and the other end bypasses the first guide rod and extends to the outside of the installation cavity through the installation cavity. The end of the first pull rope extending to one end outside the installation cavity is provided with a first pull ring;

[0099] The second driving member 407 includes a second pull rope and a second guide rod, the second guide rod is fixedly arranged at the other side of the scattering structure 201, one end of the second pull rope is connected to one end of the movable collecting plate 402 (for example, the right end of the movable collecting plate 402), and the other end bypasses the second guide rod and extends to the outside of the installation cavity through the installation cavity. A second pull ring is provided at the end of the second pull rope extending to the outside of the installation cavity.

[0100] The present invention can pull the first pull rope through the first pull ring to drive the movable collecting plate 402 and the movable connecting plate 403 to retract, and can pull the second pull rope through the second pull ring to drive the movable collecting plate 402 and the movable connecting plate 403 to extend.

[0101] like Figure 1 , Fig.11 , Fig.14 As shown, in order to solve the problem that the current domestic sewage treatment system needs to build an aeration tank and aeration equipment, resulting in high construction costs and subsequent maintenance costs, this embodiment provides a sewage treatment system, including the above-mentioned non-powered sewage aerobic device, and also includes:

[0102] An organic matter decomposition tank 50 is arranged on one side of the support and installation assembly 10. Microorganisms can decompose organic matter in sewage in the organic matter decomposition tank 50. 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 generated after sewage sedimentation and stratification in the sedimentation tank 60 to the anoxic unit 502.

[0106] It should be noted that, in the present 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] In addition, preferably, a filler is provided in the sedimentation tank 60, and the filler can be a plurality of bag fillers, and the bag fillers contain filter materials such as graphite carbon, quartz sand, ceramsite volcanic rock, etc. The provision of a plurality of bag fillers can achieve rapid stratification of the upper treated water (such as qualified water, i.e., water that meets the discharge requirements) and the lower sludge.

[0108] like Fig.12 As shown, in one embodiment, the organic matter decomposition tank 50 can adopt a rectangular organic matter decomposition tank 50, and the partition 500 can adopt 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 on 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 arranged at the upper end of the anaerobic unit 501, and the first sludge discharge outlet 506 is arranged 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 arranged at the lower end of the anoxic unit 502.

[0110] When in use, domestic sewage that has been coarsely filtered through the screen can be injected into the anaerobic unit 501 through the water inlet 505, and 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 Fig.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, which 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, and the partition tube divides the organic matter decomposition tank 50 into an anaerobic unit 501 located in 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 arranged in cooperation with the anaerobic unit 501 and a second sludge discharge outlet 507 arranged in cooperation 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, the present 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 a 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 ejected by the submersible sewage pump 508. The sewage delivery pipeline 509 can be a hose in the prior art, such as a PE hose.

[0116] like Fig.15As shown, in order to facilitate the adjustment of the position of the submersible sewage pump 508, so as to effectively pump out the sewage in the anoxic unit 502, the present 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, and 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 arranged in the anoxic unit 502 of the organic matter decomposition tank 50, the sliding mounting seat 511 is slidably arranged on the fixed mounting arm 512, the submersible sewage pump 508 is arranged on the sliding mounting seat 511, and the driving member 513 is arranged on one side of the organic matter decomposition tank 50, and is used to drive the sliding mounting seat 511 to slide on the fixed mounting arm 512.

[0117] The present invention can drive the sliding mounting seat 511 to move through the driving member 513, thereby enabling the submersible sewage pump 508 to move along the fixed mounting arm 512, thereby enabling the submersible sewage pump 508 to adjust its height in 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 disposed on the pulley mounting seat 517. The winch 516 is disposed 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 up 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. The guide pulley 514 plays a guiding role.

[0120] like Fig.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 assembly 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 port 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 port 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 externally connected to a 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 port 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 port 603, the sludge three-way valve 601 and the discharge pipe to complete the collection. Both the sludge return process and the sludge discharge process can be achieved by gravity.

[0123] Furthermore, 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 externally connected to a pipeline to a wetland.

[0124] like Figure 8 As shown, in order to facilitate the return of aerated / aerobic sewage from the breaking structure 201 to the anoxic unit 502, oxygen is brought to the anoxic unit 502. The difference between this embodiment and the above embodiment is that the sewage diversion pipe 401 extends to the end of one 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 used, the sewage that has been coarsely filtered through the screen 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, so that it is dispersed 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 breaking-up structure 201 pass through the sewage diversion component 40, a part of the sewage that has undergone the aeration / aerobic process can flow back to the anoxic unit 502 through the movable collecting plate 402, the movable connecting plate 403, the fixed collecting plate 404, the collecting pipe 405 and the sewage diversion pipe 401 to replenish oxygen for the anoxic unit 502, and the other part of the sewage that has undergone the aeration / aerobic process continues to fall, thereby continuing aeration / aerobic until it falls into the sedimentation tank 60.

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

[0130] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
