Description

Technical Field

[0001] This invention relates to the field of urban wastewater treatment technology, and in particular to a device for rapidly improving the water quality of urban water bodies. Background Technology

[0002] In recent years, with rapid economic development, wastewater treatment projects have lagged behind urban development, leading to increasingly prominent water pollution problems. This is especially true for rivers and lakes with scenic functions, which suffer from severe eutrophication due to their poor flow and low self-purification capacity. Eutrophication refers to the excessive discharge of nutrients such as nitrogen and phosphorus into natural water bodies, resulting in the overgrowth of phytoplankton such as algae. This leads to a decrease in dissolved oxygen, mass mortality of aquatic organisms, and a decline in sensory properties, all contributing to the deterioration of the aquatic ecological environment.

[0003] A search revealed a Chinese invention patent, CN104609676A, which discloses a device for rapidly improving urban water quality. The device includes: a coagulation reactor connected to the raw water inlet pipe, where wastewater undergoes suspended solids coagulation, macromolecular organic matter coagulation, and phosphorus adsorption to form pollutant flocs; an inclined tube sedimentation tank connected to the outlet of the coagulation reactor, where wastewater undergoes solid-liquid separation of the pollutant flocs formed in the coagulation reactor; a disc filter connected to the outlet of the inclined tube sedimentation tank, which intercepts fine suspended solids that could not be separated in the inclined tube sedimentation tank; and a biological activated carbon tank connected to the outlet of the disc filter, which utilizes the adsorption of activated carbon and the metabolic activity of microorganisms to reduce residual organic matter and nitrogen. Its outlet is connected to a landscape water body. This invention can rapidly improve urban water quality, is unaffected by environmental factors, and boasts a high degree of automation and low treatment costs, achieving the goal of improving landscape water quality within a cycle. The device can be skid-mounted, significantly improving utilization.

[0004] The existing treatment equipment suffers from problems such as uneven chemical dispersion due to static dosing, short-circuiting in sedimentation tanks, large footprint, easy clogging of single filter media with low interception capacity, and significant impact of influent load on effluent quality.

[0005] Therefore, the existing urban water quality rapid improvement device cannot meet the needs of actual use, so there is an urgent need for improved technology to solve the above problems. Summary of the Invention

[0019] The present invention has the following beneficial effects:

[0020] 1. This invention utilizes a protective structure on the base plate to install and place the sealing, connecting, and filtering structures during use. The adsorption and filtration tanks facilitate easy replacement of activated carbon in the filtration and adsorption structures. The sealing structure on the protective structure allows for easy addition of treatment agents to wastewater through the feeding port on the cover. The flap and sealing gasket seal the inner cavity of the protective frame, preventing secondary pollution of the water flow. The connecting structure on the protective structure allows for easy adjustment of the water flow direction and height during use. The threaded connection sleeve facilitates the connection of external pipes to the device. The system integrates the crushing and grinding mechanisms in the connecting structure. Through a worm gear-gear transmission, adjacent counter-rotating crushing blades break down large impurities (such as branches and plastic pieces) in wastewater into fragments with a particle size of <5mm. Simultaneously, mechanical stirring ensures thorough mixing of the flocculant and wastewater. This integrates the previously separate crushing and mixing processes, reducing the flocculation reaction time from the conventional 8-10 minutes to 3-5 minutes and increasing the suspended solids removal rate to 70-85%. The filtration structure on the protective junction 2, employing a sliding frame for quick replacement, allows for a single filter assembly replacement time of <5 minutes, improving efficiency by 8 times compared to traditional filter canister disassembly methods. The filter media is a quartz sand-activated carbon composite material, achieving a turbidity removal rate of 95% and a COD removal rate of 60-80% under filtration accuracy conditions of 0.5-1.2mm.

[0021] 2. This invention utilizes an isolation structure mounted on a protective structure. By adjusting the angle of the guide plate via a bidirectional electric telescopic rod, the water flow velocity can be precisely controlled from 0.8 m / s to 0.2-0.5 m / s. This dynamic adjustment creates a laminar flow in the sedimentation zone, preventing floc breakage caused by turbulence. Simultaneously, by controlling the gap between the partition plate and the guide plate, the residence time of flocs in the sedimentation zone is extended by 20-30%, promoting the growth of floc particles to 0.5-1 mm and increasing the settling velocity by 40%. The separation structure below the isolation structure, with its overflow trough design, automatically overflows when the water level reaches a set height, preventing overloading of the sedimentation zone. The L-shaped separation plate achieves a 92% interception rate for floating debris (such as oil film and algae). Combined with the sudden drop in water flow velocity during overflow (from 0.5 m / s to 0.1 m / s), this ensures... The removal rate of pollutants with suspended oil droplet diameter >50μm reaches over 95%. Through the flow control structure between the separation structures, the flow direction of the filtered water is limited by the cooperation of the sealing plate and the rotating shaft during operation. This allows personnel to easily adjust and control the water flow rate and velocity via the flow-driven structure. The flow-driven structure on the protective structure drives the rotation of the rotating shaft during operation, and the control of the worm gears causes the two rotating shafts to rotate in opposite directions. Therefore, the flow rate and velocity of the water supplied to the adsorption structure between the separation racks are quantified. Through the adsorption structure on the bottom plate and the sliding placement rack, the replacement time for a single set of activated carbon is <8 minutes. Furthermore, through layered filling (top layer of coarse-porous carbon, bottom layer of microporous carbon), the adsorption efficiency for macromolecular organic matter with a molecular weight >1000Da is increased by 40%. Actual operation data shows that the device removes 50.9% and 61.0% of model pollutants such as humic acid and bovine serum albumin, respectively. The treated water has a color ≤15 degrees and an odor threshold <3.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The protective structure 2 includes a protective frame 21 fixedly connected to the upper end face of the base plate 1. An adsorption groove 22 is provided on the lower end face of the protective frame 21, and a filter groove 23 penetrating the protective frame 21 is provided on the upper part of the front end face of the protective frame 21. An adsorption structure 10 is provided in the inner cavity of the adsorption groove 22, and a filter structure 6 is slidably connected in the inner cavity of the filter groove 23. A sealing structure 3 is fixedly connected to the upper end face of the protective frame 21. Through the protective structure 2 on the base plate 1, the sealing structure 3, the connecting structure 4, and the filter structure 6 can be installed and placed during use. In turn, the activated carbon in the filter structure 6 and the adsorption structure 10 can be easily replaced by personnel through the adsorption groove 22 and the filter groove 23.

[0036] Furthermore, the sealing structure 3 includes a cover plate 31 fixedly connected to the upper end face of the protective frame 21. A feeding port is provided in the middle of the upper end face of the cover plate 31. A flap 32 is rotatably connected to the upper end face of the cover plate 31 on the side of the feeding port via a bracket. A sealing gasket 33 matching the feeding port is fixedly connected to the lower end face of the flap 32. Through the sealing structure 3 on the protective structure 2, it is convenient for personnel to add treatment agents to sewage through the feeding port on the cover plate 31 during use. Then, the flap 32 and the sealing gasket 33 seal the inner cavity of the protective frame 21 to avoid secondary pollution of the water flow.

[0037] Furthermore, the connection structure 4 includes a water outlet pipe 41 fixedly connected to the lower part of the rear end face of the protective frame 21, and a water inlet pipe assembly 42 fixedly connected to the upper part of the right end face of the protective frame 21. Threaded connecting sleeves 43 are fixedly connected to the outer surfaces of the water outlet pipe 41 and the water inlet pipe assembly 42 on the side away from the protective frame 21. Through the connection structure 4 on the protective structure 2, it is convenient for personnel to adjust the flow direction and height of the water flow during use, and the threaded connecting sleeves 43 facilitate the connection of external pipes and devices.

[0038] Furthermore, the crushing structure 5 includes a crushing blade 51 uniformly rotatably connected to the inner cavity of the protective frame 21 and located below the inlet pipe assembly 42. A gear set 52, matching the crushing blade 51, is rotatably connected to the rear end face of the protective frame 21. The shaft of the rear end face of the crushing blade 51 passes through the protective frame 21 and is fixedly connected to the gear set 52. A worm gear 53 is rotatably connected to one side of the gear set 52 at the rear end of the protective frame 21 via a bracket. The worm gear 53 meshes with a gear on one side of the gear set 52. A crushing motor 54 is fixedly connected to the upper part of the worm gear 53 at the rear end face of the protective frame 21. The shaft of the upper end face of the worm gear 53 passes through the bracket and is fixedly connected to the output end of the crushing motor 54. Through the crushing structure 5 on the connecting structure 4, the adjacent counter-rotating crushing blades 51 are driven by the worm gear-gear set transmission to crush large impurities (such as branches and plastic pieces) in the wastewater into fragments with a particle size <5mm. Simultaneously, mechanical stirring ensures thorough mixing of the flocculant and wastewater. This integrates the independent crushing and mixing processes in traditional processes, reducing the flocculation reaction time from the conventional 8-10 seconds. The time has been shortened to 3-5 minutes, and the removal rate of suspended solids has been increased to 70-85%.

[0039] Furthermore, the filter structure 6 includes a sliding frame 61 slidably connected to the inner cavity of the filter tank 23. A filter plate 62 is fixedly connected to the lower end face of the inner cavity of the sliding frame 61, and a handle is fixedly connected to the middle of the front face of the sliding frame 61. There are multiple filter structures 6, and the gap between the filter plates 62 decreases sequentially. Through the filter structure 6 on the protective structure 2, and by adopting the quick-replacement design of the sliding frame 61, the replacement time for a single filter assembly is less than 5 minutes, which is 8 times more efficient than the traditional filter canister disassembly method. The filter media is selected as quartz sand-activated carbon composite filter media. Under the condition of filtration accuracy of 0.5-1.2mm, the turbidity removal rate reaches 95%, and the COD removal rate is 60-80%.

[0040] Furthermore, the isolation structure 7 includes a partition plate 71 fixedly connected to the inner cavity of the protective frame 21, located below the filter structure 6. A guide plate 72 is symmetrically connected to the inner cavity of the protective frame 21 via a rotating rod, with the partition plate 71 as the center line. A flow control structure 73 is located on the left end face of the protective frame 21, matching the position of the guide plate 72. The flow control structure 73 includes a connecting rod 731 symmetrically rotatably connected to the left end face of the protective frame 21. The rotating shaft on the left end face of the two guide plates 72's rotating rod passes through the partition plate 72 of the protective frame 21. The first connecting rod 731 is fixedly connected to the second connecting rod 732. The end of the first connecting rod 731 away from the guide plate 72 is rotatably connected to the second connecting rod 732. The left end of the protective frame 21 is fixedly connected to the bidirectional electric telescopic rod 733 between the two connecting rods 731. The ends of the two connecting rods 732 away from the first connecting rod 731 are rotatably connected to the two ends of the bidirectional electric telescopic rod 733. Through the isolation structure 7 on the protective structure 2, the angle of the guide plate 72 can be adjusted by the bidirectional electric telescopic rod, and the water flow velocity can be precisely controlled from 0.8m / s to 0.2-0.5m / s. This dynamic adjustment makes the sedimentation zone form a laminar flow state, avoiding floc breakage caused by turbulence. At the same time, through the gap control between the partition plate 71 and the guide plate 72, the residence time of flocs in the sedimentation zone is extended by 20-30%, promoting the alum floc particles to increase to 0.5-1mm, and increasing the settling velocity by 40%.

[0041] Furthermore, the separation structure 8 includes a separation frame 81 fixedly connected to the lower end face of the partition plate 71. Overflow channels 82 are evenly provided on the adjacent upper sides of the two separation frames 81. A separation plate 83 is fixedly connected to the end of the separation frame 81 away from the overflow channel 82. A fisherman flow control structure 9 is fixedly connected to the lower end face of the separation frame 81. Through the separation structure 8 below the isolation structure 7, the overflow channel 82 is designed to automatically overflow when the water level reaches the set height, avoiding overload operation of the sedimentation zone. The separation plate 83 adopts an L-shaped structure, which has an interception rate of 92% for floating objects (such as oil film and algae) on the water surface. Combined with the sudden drop in water flow velocity during the overflow process (from 0.5m / s to 0.1m / s), the removal rate of pollutants with suspended oil droplet particle size >50μm reaches more than 95%.

[0042] Furthermore, the flow control structure 9 includes a sealing plate 91 fixedly connected to the lower end face of the partition plate 71. The inner cavity of the protective frame 21 is symmetrically rotatably connected to the two sealing plates 91, and a flow-blocking plate is uniformly fixedly connected to the outer surface of the rotating shaft 92. A flow drive structure 93 is provided on the left end face of the protective frame 21. Through the flow control structure 9 between the separation structures 8, the flow direction of the filtered water is limited by the cooperation of the sealing plate 91 and the rotating shaft 92 during use, so that personnel can easily adjust and control the water flow rate and velocity through the flow drive structure 93.

[0043] Furthermore, the flow drive structure 93 includes a worm gear 931 symmetrically rotatably connected to the lower left end face of the protective frame 21. The left end face of the rotating shaft 92 passes through the protective frame 21 and is fixedly connected to the two worm gears 931 respectively. The left end face of the protective frame 21 is located between the two worm gears 931 and is rotatably connected to the drive worm 932 through a bracket. The lower end face of the drive worm 932 passes through the bracket and is fixedly connected to the output end of the flow motor 933. Through the flow drive structure 93 on the protective structure 2, the rotation of the rotating shaft 92 is driven during use. Then, by controlling the drive worm gear 932 and the worm gear 931, the two rotating shafts 92 rotate in opposite directions. Therefore, the flow rate and velocity of the water flow delivered between the separation frames 81 to the adsorption structure 10 are quantified.

[0044] Furthermore, the adsorption structure 10 includes a slide rail 101 symmetrically fixedly connected to the lower end face of the inner cavity of the adsorption tank 22. A placement plate 102 is slidably connected to the upper end face of the slide rail 101 via a slider. A placement rack 103 is fixedly connected to the upper end face of the placement plate 102. Water outlet grooves 104 are evenly distributed on the front end face of the placement rack 103. Activated carbon is placed inside the placement rack 103. The placement rack 103, the placement plate 102, and the inner cavity of the adsorption tank 22 are mutually sealed. Through the adsorption structure 10 on the bottom plate 1 and the sliding placement rack 103 via the slide rail 101, the replacement time for a single set of activated carbon is <8 minutes. Furthermore, through layered filling (upper layer of coarse-porous carbon, lower layer of microporous carbon), the adsorption efficiency for macromolecular organic matter with a molecular weight >1000 Da is increased by 40%. Actual operation data shows that the device achieves removal rates of 50.9% and 61.0% for model pollutants such as humic acid and bovine serum albumin, respectively. The treated water has a color ≤15 degrees and an odor threshold <3.

[0045] Working principle: During operation, the water source is connected to the threaded connection sleeve 43 on the inlet pipe assembly 42 through a pipe. At this time, the water flows into the inner cavity of the protective frame 21 through the inlet pipe assembly 42. Simultaneously, the flap 32 is pulled to open it. Then, the flocculant is added to the water through the feeding port on the cover plate 31.

[0046] At this time, the pulverizing structure 5 is activated, causing the output end of the pulverizing motor 54 to rotate. Therefore, the worm gear 53 rotates. Since the worm gear 53 meshes with the gears on one side of the gear set 52, and adjacent gears in the gear set 52 mesh with each other, all gears in the gear set 52 rotate in opposite directions. Because the gear set 52 is fixedly connected to the pulverizing blade 51, the pulverizing blade 51 rotates, and adjacent pulverizing blades 51 rotate in opposite directions. This achieves the pulverization of impurities in the wastewater. Simultaneously, the rotation of the pulverizing blade 51 mixes the flocculant with the wastewater, thereby achieving flocculation and sedimentation of impurities in the wastewater.

[0047] The flow guiding control structure 73 is activated, causing the bidirectional electric telescopic rod 733 to retract. This brings the two connecting rods 732 closer together, causing the connecting rod 731 to rotate relative to each other. Consequently, the guide plates 72 rotate in opposite directions. Water then flows through the gap between the partition plate 71 and the guide plate 72 into the separation structure 8. Since the water has entered the separation structure 8, after being crushed and settled, it needs to pass through the filter structure 6. Therefore, the filter structure 6 filters and separates impurities and sediments from the water flow.

[0048] Water accumulates and brings the water surface close to the separator 81. The water overflows through the overflow trough 82 on the separator 81, while the separator 83 isolates floating impurities. This further ensures the treated water flows between the two separators 81. At this point, the flow control structure 9 is activated, causing the output of the flow motor 933 to rotate, which in turn drives the worm gear 932. Since the worm gear 932 meshes with the worm gear 931, the worm gear 931 rotates. Because the worm gear 931 is fixedly connected to the rotating shaft 92, the downstream flow rate and velocity of the water are controlled and regulated.

[0049] When water flows into the inner cavity of the placement rack 103, the activated carbon inside the placement rack 103 adsorbs dissolved organic matter and gases in the water. When it is necessary to replace the adsorption structure 10 and the filter structure 6...

[0050] Pull the handle on the sliding frame 61 to slide the sliding frame 61 in the inner cavity of the filter tank 23, thereby removing the filter structure 6 from the protective structure 2, and then inserting another filter structure 6 into the inner cavity of the filter tank 23. At the same time, pull the placement frame 103 to slide the adsorption structure 10 on the slide rail 101, thereby removing the placement plate 102 and the placement frame 103 from the adsorption tank 22, thereby replacing the activated carbon in the inner cavity of the placement frame 103.
