Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0045] Example 1

[0046] Reference Figure 1 to Figure 10 As shown in the figure, it is the first embodiment of the present invention, which provides an oxidation combined membrane ultrafiltration integrated device, which includes a grid well 100, a flocculation tank 200, an oxidation tank 300 and a filtration tank 400 in sequence, and the flocculation tank 200 and the oxidation tank 300 are both provided with baffles 800 for deflection, and the grid well 100, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 are connected through an intermediate pipe 500, and the surface of the grid well 100 is provided with a water inlet pipe 101 for water inlet, and the surface of the filtration tank 400 is provided with a water outlet pipe 102 for water outlet. The sewage enters the grid well 100, the intermediate pipe 500, the flocculation tank 200, the intermediate pipe 500, the oxidation tank 300, the intermediate pipe 500, the filter tank 400 in sequence through the water inlet pipe 101, and then flows out through the water outlet pipe 401. The water inlet pipe 101 and the water outlet pipe 401 are provided with a throttle valve 102 for adjusting and controlling the liquid flow rate. The intermediate pipe 500 between the grid well 100, the flocculation tank 200, the oxidation tank 300 and the filter tank 400 is provided with a baffle 510. 0 is used to control the opening or closing of the intermediate pipeline 500, the baffle 510, through the throttle valve 102 and the baffle 510 to achieve the interconnection or non-interference of the grid well 100, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400. When the baffle 510 rotates 90°, it is in the open state, and when the baffle 510 is reset, it is in the closed state; the baffle 510 is provided with a driving unit 600 for adjusting the angle of the baffle 510, and the baffle 510 is adjusted by the driving unit 600 to block the intermediate pipeline 500, The three groups of deflectors 510 are driven by the driving unit 600 at the same time to realize synchronous rotation. When the three groups of deflectors 510 are adjusted to rotate by the driving unit 600, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 do not interfere with each other. Flocculant is added into the flocculation tank 200 to realize flocculation and precipitation of suspended matter in the sewage. The organic matter in the sewage is degraded by the synergistic effect of adding hydrogen peroxide oxidizing agent and ultraviolet lamp 321 into the oxidation tank 300. The filtration tank 400 is provided with an ultrafiltration membrane 411 for deep filtration of the sewage.

[0047] A multi-stage grid 110 is horizontally installed in the grid well 100. The multi-stage grid 110 includes an L-shaped grid plate 111 and a block grid plate 112 which are connected in one piece. After being combined, the vertical cross-section of the L-shaped grid plate 111 and the block grid plate 112 is triangular, occupies a small space, and has a multi-stage filtering function, and is used for preliminary filtering of sewage.

[0048] Among them, refer to Figure 8 As shown, the size of the grille holes on the surface of the block grille plate 112 is twice the size of the grille holes on the surface of the L-shaped grille plate 111. The multi-stage grille 110 and the grille well 100 are interference fit, and the multi-stage grille 110 is pressed into the grille well 100 by pressure. The multi-stage grille 110 is used to perform preliminary treatment on the sewage in the water inlet pipe 101, and the preliminary filtered sewage passes through the multi-stage grille 110 into the grille well 100.

[0049] Reference Figure 1 , Figure 2 as well as Fig. 9 As shown, two groups of membrane assemblies 410 for deep filtration are installed in the filter tank 400, and the membrane assembly 410 includes an ultrafiltration membrane 411 and a frame 412 surrounding the edge of the ultrafiltration membrane 411, which is convenient for timely replacement without hindering the deep filtration of sewage. Two groups of gear bars for inserting the ultrafiltration membrane 411 are provided in the filter tank 400, and each group of gear bars includes two strips. The gap between the two groups of gear bars is the thickness of the frame 412.

[0050] Reference Figure 1~Figure 3 As shown, it also includes a driving assembly and a liquid storage tank 210, the driving assembly includes a rotating structure 220 and a displacement component 230, the displacement component 230 is used to connect the liquid storage tank 210 and the flocculation tank 200, and the displacement component 230 is used to control the movement of the liquid storage tank 210; wherein, a triangular extension block 310 is installed at the top of the flocculation tank 200, and the rotating structure 220 drives the liquid storage tank 210 to move upward along the triangular extension block 310 to store gravity energy, and based on the gravity energy storage, kinetic energy is provided for the liquid storage tank 210 to reset when it moves downward along the inclined plane, and medication is performed when the liquid storage tank 210 moves upward or downward.

[0051] Reference Figure 1 As shown, triangular extension blocks 310 are provided at the top of the flocculation tank 200 and the oxidation tank 300, and displacement components 230 are provided in the flocculation tank 200 and the oxidation tank 300. To avoid logical confusion in the description, only one of them is selected for description in this article.

[0052] The rotating structure 220 is used to mix the reagent and the sewage;

[0053] The displacement assembly 230 includes a traction rope 240 that passes through and is connected to the surface wall of the flocculation tank 200;

[0054] The displacement assembly 230 further includes a pushing unit 700, wherein the rotating structure 220 penetrates the flocculation tank 200 and is connected to the pushing unit 700, and the pushing unit 700 drives the rotating structure 220 to rotate, and pulls the displacement assembly 230 and the liquid storage tank 210 to move upward along the triangular extension block 310 through the traction rope 240 to store gravity energy;

[0055] Among them, there are two groups of triangular extension blocks 310, and the two groups of triangular extension blocks 310 are respectively installed on the top walls of the flocculation tank 200 and the oxidation tank 300, and each group of triangular extension blocks 310 has two blocks, and the two triangular extension blocks 310 are installed on the two long side walls of the flocculation tank 200 or the oxidation tank 300.

[0056] The liquid storage tank 210 located on the flocculation tank 200 is loaded with flocculant, and the liquid storage tank 210 located on the oxidation tank 300 is loaded with oxidant. The device is equipped with a hydrogen peroxide solution. At the same time, a generator 320 is installed on the top of the oxidation tank 300. The generator 320 includes a multi-tube ultraviolet lamp 321 and a lamp holder 322 for installing the ultraviolet lamp 321. The organic matter in the sewage is degraded by the synergistic effect of hydrogen peroxide and ultraviolet rays, thereby achieving the degradation of organic matter in the sewage.

[0057] If the oxidant and flocculant are to be used at their maximum efficiency and the sewage is to be treated comprehensively, it is necessary to ensure that the oxidant and the flocculation tank 200 are completely and evenly mixed in the sewage. The device provides a rotating structure 220, through which a high degree of mixing of the sewage is achieved. However, this method only ensures that the oxidant or flocculant is mixed only in a certain area and cannot spread along the axial direction of the rotating structure 220. However, if a spoiler is provided that moves along the axial direction of the rotating structure 220, the space required is relatively large, and the sewage is required to have a certain depth in the longitudinal direction to ensure the synergistic effect of the axial and radial spoilers. However, sewage with a certain depth has certain requirements on the radiation depth of the ultraviolet lamp 321.

[0058] The device is provided with a movable displacement component 230 and a liquid storage tank 210 to achieve directional movement of the liquid storage tank 210 to ensure uniform input of the oxidant and the flocculant, and at the same time cooperate with the rotating structure 220 to improve the utilization efficiency of the oxidant and the flocculant to improve the comprehensiveness of sewage treatment.

[0059] The rotating structure 220 includes a shaft that passes through the flocculation tank 200 or the oxidation tank 300 and a plurality of blades mounted on the shaft. When the rotating structure 220 is driven by the driving unit 700, the plurality of blades on the shaft disturb the water flow, so that the water flow rotates with the blades. At the same time, the rotating structure 220 rotates intermittently by alternating forward and reverse rotations. This alternating forward and reverse rotation can break the vortex structure in the fluid, making the material distribution in the fluid more even, helping to reduce mixing dead corners, and ensuring that all areas can be fully stirred.

[0060] Reference Figure 6~Figure 10 As shown, the deflector 510 includes a ball 511 installed in the middle pipe 500, a valve stem 512 passing through the ball 511, and a ring gear 513 fixed to the top of the valve stem 512. The ring gear 513 is adjusted by the driving unit 600 and then controls the rotation of the ball 511 through the valve stem 512 to deflect the fluid in the pipe.

[0061] The driving unit 600 includes a cylinder 610 and a connecting truss. The output shaft of the cylinder 610 is fixedly connected to a bent rod 640. The end of the bent rod 640 away from the cylinder 610 is connected to the connecting truss. The connecting truss includes a moving rod 620 and a connecting rod 630. The moving rod 620 and the connecting rod 630 form a frame structure. The moving rod 620 is connected to the bent rod 640 so that when the cylinder 610 drives the bent rod 640 to reciprocate, the connecting truss is synchronously driven to reciprocate. The moving rod 620 is provided with a rack meshing with the ring gear 513 so that the ring gear 513 is driven to rotate when the connecting truss moves. The deflector 510 is moved to realize the opening and closing control of the deflector 510 to adjust the opening or closing of the intermediate pipe 500. Since the deflector 510 is designed as a ball valve, during the movement of the moving rod 620, it is meshed with the two adjacent ring gears 513 at the same time, so that the adjacent ring gears 513 rotate in opposite directions. Due to the structure of the deflector 510, the deflector 510 can be opened by rotating it 90º or rotating it in the opposite direction, that is, the moving rod 620 drives the two adjacent ring gears 513 to rotate in the opposite direction to synchronously control the synchronous opening or closing of the adjacent intermediate pipes 500.

[0062] When the liquid level in the grid well 100 drops to the target low liquid level, the throttle valves 102 on the water inlet pipe 101 and the water outlet pipe 401 are opened, and the driving unit 600 adjusts the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit to rotate 90 degrees in the opposite direction. At this time, the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit are all in a closed state, and the sewage entering the flocculation tank 200 is flocculated and precipitated, the sewage entering the oxidation tank 300 is oxidized and degraded, and the sewage entering the filtration tank 400 is deeply filtered;

[0063] When the liquid level in the grid well 100 reaches the target high liquid level, the throttle valves 102 on the water inlet pipe 101 and the water outlet pipe 401 are closed, and the driving unit 600 adjusts the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit to rotate forward by 90°. At this time, the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit are all in an open state, and the grid well 100, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 are connected, and the sewage enters the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 in sequence. The sewage in the grid well 100 enters the flocculation tank 200 and is diverted to the top of the flocculation tank 200 by the baffle 800. The flocculated and purified sewage in the flocculation tank 200 is squeezed into the oxidation tank 300 and diverted to the top of the oxidation tank 300 by the baffle 800. The oxidized and degraded sewage in the oxidation tank 300 is squeezed into the filtration tank 400. The liquid level in the grid well 100 is reduced to the target low liquid level.

[0064] The above steps are repeated to continuously purify, oxidize and filter the sewage. This arrangement is not only for separating the various sewage treatment processes to avoid interference, but also for retaining the sewage in the screen well 100, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 during the time period corresponding to the intermittent opening and closing of the throttle valve 102 to ensure sufficient action time, thereby maximizing the sewage treatment efficiency.

[0065] The side walls of the flocculation tank 200 and the oxidation tank 300 are both extended upward with triangular extension blocks 310, which support the displacement assembly 230. The displacement assembly 230 includes a central hole plate 231 for supporting the liquid storage tank 210, a semicircular guard frame 232 vertically inserted in the central hole plate 231, and an L-shaped plate 233. The traction rope 240 is fixed to one end of the L-shaped plate 233 and passes through the flocculation tank 200 or the oxidation tank 300, and the displacement assembly 230 is pulled by the traction rope 240 to move along the length direction of the triangular extension block 310. The L-shaped plate 233 moves synchronously with the displacement assembly 230. When the traction rope 240 is pulled by the pushing unit 700, the displacement assembly 230 is pulled to move along the length direction of the triangular extension block 310. When the pushing unit 700 no longer pulls the traction rope 240, the displacement assembly 230 automatically slides down along the inclined surface of the triangular extension block 310 due to gravity under the action of gravity, so as to realize the reciprocating motion of the displacement assembly 230.

[0066] In order to ensure that the displacement component 230 can automatically slide down along the inclined surface of the triangular extension block 310 due to gravity, the contact parts of the triangular extension block 310, the pool wall and the displacement component 230 are all smoothed to reduce the friction between the displacement component 230 and the triangular extension block 310 and the pool wall.

[0067] The driving unit 700 includes a speed regulating motor 710 and two supporting rollers 720. The two supporting rollers 720 are fixed to one end of the rotating structure 220 that passes through the flocculation tank 200 and the oxidation tank 300. The speed regulating motor 710 drives the rotating structure 220 to rotate through the supporting rollers 720.

[0068] The other ends of the two sets of rotating structures 220 passing through the flocculation tank 200 and the oxidation tank 300 are fixed with multi-groove pulleys 250 , and multiple belts 260 are transmitted between the two sets of multi-groove pulleys 250 . The two sets of multi-groove pulleys 250 are synchronously driven through the multiple belts 260 .

[0069] The speed regulating motor 710 drives a group of multi-groove pulleys 250 to rotate through the supporting roller 720 and the rotating structure 220, and the two groups of multi-groove pulleys 250 are synchronously transmitted through multiple belts 260. The two groups of multi-groove pulleys 250 rotate synchronously with the two groups of rotating structures 220, that is, the speed regulating motor 710 drives the two groups of rotating structures 220, the two supporting rollers 720 and the two groups of multi-groove pulleys 250 to rotate.

[0070] The pushing unit 700 also includes a linkage structure 730 , which includes a tensioning roller 731 and a driving belt 732 . The speed regulating motor 710 , the supporting roller 720 and the driving belt 732 drive the tensioning roller 731 to rotate, and the traction rope 240 is wound around the surface of the tensioning roller 731 .

[0071] When the two support rollers 720 rotate, the support roller 720 drives the tensioning roller 731 to rotate through the driving belt 732, and the traction rope 240 is wound around the surface of the tensioning roller 731, thereby pulling the displacement component 230 to move upward along the surface of the triangular extension block 310 to store gravity energy, and the liquid storage tank 210 moves forward; when the support roller 720 drives the tensioning roller 731 to rotate in the opposite direction through the driving belt 732, the traction rope 240 is gradually unwound from the surface of the tensioning roller 731, and the displacement component 230 slides down at a uniform speed under the action of gravity and the pull of the traction rope 240, and the liquid storage tank 210 moves in the opposite direction. The liquid storage tank 210 releases liquid during the forward and reverse movements, thereby achieving uniform discharge of flocculants and oxidants and improving the utilization efficiency of flocculants and oxidants.

[0072] Working principle: the flocculation baffle unit, oxidation baffle unit and filtration baffle unit are closed, and the throttle valves 102 on the water inlet pipe 101 and the water outlet pipe 401 are closed. At this time, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 do not interfere with each other. In the initial state, part of the water needs to be filled into the flocculation tank 200 and the oxidation tank 300 so that the liquid level rises to a level that exceeds the target low liquid level.

[0073] Open the throttle valves 102 on the water inlet pipe 101 and the water outlet pipe 401, and the sewage enters the grid well 100, and is coarsely filtered twice by the block grid plate 112 and the L-shaped grid plate 111 in the grid well 100. After filtering out large particles, block or strip impurities in the sewage, the sewage enters the grid well 100, and the liquid that slowly enters is slowly accumulated until the sewage in the grid well 100 reaches the target high liquid level;

[0074] When the liquid level in the grid well 100 reaches the target high liquid level, the throttle valve 102 on the water inlet pipe 101 and the water outlet pipe 401 is closed, and the driving unit 600 adjusts the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit to rotate forward by 90 degrees. At this time, the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit are all in the open state, and the grid well 100, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 are connected, and the sewage enters the flocculation tank 200 in sequence. 0. In the oxidation tank 300 and the filter tank 400, the sewage in the grille well 100 enters the flocculation tank 200 and is diverted by the baffle 800 to the top of the flocculation tank 200. The flocculated and purified sewage in the flocculation tank 200 is squeezed into the oxidation tank 300 and diverted by the baffle 800 to the top of the oxidation tank 300. The oxidized and degraded sewage in the oxidation tank 300 is squeezed into the filter tank 400. At the same time, the liquid in the grille well 100 enters the flocculation tank 200, causing the liquid level to decrease.

[0075] When the liquid in the grid well 100 enters the flocculation tank 200, causing the liquid level to decrease. When it drops to the target low liquid level, the throttle valve 102 on the water inlet pipe 101 and the water outlet pipe 401 is opened, and the driving unit 600 adjusts the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit to rotate 90 degrees in the opposite direction. At this time, the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit are all in a closed state, and the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 do not interfere with each other. 00 releases the flocculant from the storage tank 210, and the oxidant from the storage tank 210 in the oxidation tank 300 is released. At the same time, the ultraviolet lamp 321 is turned on, and the speed regulating motor 710 drives a set of multi-groove pulleys 250 to rotate through the support roller 720 and the rotating structure 220, and the two sets of multi-groove pulleys 250 are synchronously driven by multiple belts 260. The two sets of multi-groove pulleys 250 rotate synchronously with the two sets of rotating structures 220, that is, the speed regulating motor 710 drives the two sets of rotating structures 220 and the two support rollers 720. The roller 720 and the two sets of multi-groove pulleys 250 rotate, and the two support rollers 720 drive the tension roller 731 to rotate through the drive belt 732. The traction rope 240 is wound around the surface of the tension roller 731, thereby pulling the displacement component 230 to slide obliquely upward on the surface of the triangular extension block 310. The liquid storage tank 210 moves forward while discharging liquid, and the discharged liquid is stirred by the turbulent rotating structure 220, so that it is fully mixed with the sewage; when the support roller 720 drives the tension roller 731 to rotate in the opposite direction through the drive belt 732, When rotating, the traction rope 240 is gradually unwound from the surface of the tension roller 731, and the displacement assembly 230 slides down at a uniform speed under the action of gravity and the pull of the traction rope 240. The liquid storage tank 210 moves in the opposite direction while releasing the liquid. The rotating structure 220 moving in the opposite direction breaks the original vortex structure in the fluid, so that the medicine is mixed more evenly, and the liquid in the dead corner is also brought out for mixing. The liquid storage tank 210 releases the liquid during the forward and reverse movements, so as to achieve the uniform release of the flocculant and the oxidant, and improve the utilization efficiency of the flocculant and the oxidant.

[0076] When the low liquid level rises to the high liquid level, the flocculant mixes with the sewage, causing the suspended matter in the sewage to settle, the sewage in the oxidation tank 300 to be degraded, and the stirring structure increases the reaction process.

[0077] When the liquid in the water inlet pipe 101 enters the grille well 100, causing the liquid level in the grille well 100 to rise, and when it rises to slightly above the target high liquid level, the driving unit 600 adjusts the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit to rotate forward 90°. At this time, the flocculation baffle unit, the oxidation baffle unit and the filtration baffle unit are all in the open state, and the grille well 100, the flocculation tank 200, the oxidation tank 300 and the filtration tank 400 are connected. The filtration tank 400 discharges the deeply purified sewage, and the above process is repeated until all the sewage is treated.

[0078] The baffle 800 is provided to prevent the sewage from entering the flocculation tank 200 and being discharged directly from the outlet of the flocculation tank 200. The baffle 800 separates the treated sewage from the newly entered sewage to ensure that the sewage entering the next process has been treated by the previous process. Secondly, in order to ensure that the flocculant and the oxidant have sufficient reaction time, the speed at which the sewage enters the water inlet pipe 101 is relatively slow.
