[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] This embodiment describes an integrated water treatment system, referring to... Figure 1-21 The system includes a pool body 600 consisting of a pool bottom and pool walls. The pool body 600 is assembled from multiple panels to form an integrated unit. Inside the pool body 600, in the direction of water flow, there are flocculation reaction unit 100, sedimentation unit 300, water collection unit 400, and filtration unit 500 arranged sequentially. All of these units are prefabricated modules. The purification efficiency coefficient of the integrated water treatment system ranges from 13.0 to 18.0, and the purification efficiency coefficient is the ratio of the daily water treatment volume to the pool volume.

[0028] The flocculation reaction unit 100, sedimentation unit 300, water collection unit 400, and filtration unit 500 are all prefabricated components, manufactured in a standardized manner in the factory in advance to achieve mass production. The entire process is highly mechanized and efficient. The prefabricated modules are directly transported to the construction site for installation, which greatly shortens the construction cycle and saves time and labor costs.

[0029] In some embodiments, refer to Figure 2 , Figure 7 The flocculation reaction unit 100 includes a flocculation reaction tank area sliding plate 110, a flocculation reaction tank area sludge discharge pipe 120, a vertical shaft longitudinal baffle 130, a vertical shaft transverse baffle 140, and a flocculation reactor 150. The flocculation reaction tank area sliding plate 110 and the flocculation reaction tank area sludge discharge pipe 120 are located at the bottom of the tank. A bucket-shaped flocculation reaction tank sludge accumulation area 160 is formed between the two flocculation reaction tank area sliding plates 110 that are relatively inclined. The flocculation reaction tank area sludge discharge pipe 120 is arranged in the flocculation reaction tank sludge accumulation area 160. The vertical shaft longitudinal baffle 130 and the vertical shaft transverse baffle 140 are located above the flocculation reaction tank area sludge discharge pipe 120. Multiple vertical shaft longitudinal baffles 130 and multiple vertical shaft transverse baffles 140 interweave to form a grid structure. Each grid is an independent reaction zone 170. The flocculation reactor 150 is located in the reaction zone 170.

[0030] In some embodiments, flow-through perforations are provided on the vertical baffle 130 and / or the horizontal baffle 140 of the shaft, allowing water in the reaction zone 170 to flow sequentially into adjacent reaction zones 170 through these perforations. Raw water enters the reaction zone 170 through the perforations and flows sequentially through multiple reaction zones 170 in an upward or downward manner, significantly extending the flow path and mixing time of the raw water and flocculant, thus achieving a balance between the limited volume of the tank and the mixing efficiency. Figure 11 This illustrates a raw water flow path.

[0031] In some embodiments, the flocculation reactor 150 may be a grid reactor, such as a stacked double-effect flocculation reactor. Figure 12 ), vortex flocculation reactor ( Figure 13 ).

[0032] In some embodiments, the flow of raw water between the grid formed by the interlacing of the longitudinal baffles 130 and the transverse baffles 140 of the shaft forms a flocculation path, which is at least divided into two segments: One type is a two-section structure consisting of a front section and a rear section. In the reaction zone of the front section of the flocculation path, the number of layers of the flocculation reactor 150 is greater than or equal to the number of layers of the flocculation reactor 150 in the rear section.

[0033] Secondly, it has a three-stage structure: front-stage, middle-stage, and final-stage. In the reaction zone of the front-stage flocculation path, the number of layers of flocculation reactor 150 is greater than or equal to the number of layers of flocculation reactor 150 in the middle stage, and the number of layers of flocculation reactor 150 in the middle stage is greater than or equal to the number of layers of flocculation reactor 150 in the final stage. For example, the front-stage flocculation reactor 150 has 3-4 layers, the middle-stage flocculation reactor 150 has 2-3 layers, and the final-stage flocculation reactor 150 has 0-2 layers. Figure 7 .

[0034] In some embodiments, refer to Figure 2 , Figure 3 , Figure 7 The sedimentation unit 300 includes a sedimentation tank area mud plate 310, a sedimentation tank area sludge discharge pipe 320, a sedimentation device 330, and a sedimentation device mounting base 340. A bucket-shaped sedimentation tank sludge accumulation area 350 is formed between two relatively inclined sedimentation tank area mud plates 310. The sedimentation tank area sludge discharge pipe 320 is arranged in the sedimentation tank sludge accumulation area 350. The sedimentation device mounting base 340 is arranged above the sedimentation tank area sludge discharge pipe 320. The sedimentation device 330 is fixed to the top of the sedimentation device mounting base 340.

[0035] In some embodiments, refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8The water collection unit 400 includes an outlet water collection plate 411, a weir channel 412, a filter zone partition 413, and an outlet mud plate 414. The outlet water collection plate 411 and the filter zone partition 413 are vertically arranged opposite each other. The weir channel 412 is fixed on the filter zone partition 413 and together with the filter zone partition 413, they enclose an outlet channel 415. The outlet mud plate 414 divides the space between the outlet water collection plate 411 and the filter zone partition 413 into the upper outlet channel. The water rectification zone 416 and the backwash drainage zone 417 below it are provided with water through openings 418 on the part of the water collection plate 411 located in the water rectification zone 416. The filter zone inlet 419 is provided on both sides of the filter zone partition 413 and located in the water outlet channel 415. The part of the filter zone partition 413 located in the backwash drainage zone 417 is provided with a backwash drain outlet 420. The backwash drainage zone 417 is connected to a backwash drain pipe 640.

[0036] In some embodiments, refer to Figure 2 , Figure 4 , Figure 5 The filtration unit 500 includes a water distribution channel 511, filter plates 521, filter heads 522, a backwash drainage channel 531, and a backwash baffle 532. The water distribution channel 511 spans the tank body 600 and its end connects to the filter area inlet 419. Multiple filter area inlet perforations 512 are provided on the water distribution channel 511. The filter plates 521 are laid horizontally within the tank body 600, and the filter heads 522 are fixed to the filter plates 521. Filter media is laid on the filter plates 521. The cross-section of the filter plates 521 adopts a continuous wavy or trapezoidal structure, which can effectively enhance the strength and rigidity of the filter plates 521. The backwash drainage channel 531 is parallel to the water distribution channel 511 and is arranged between adjacent filter plates 521. There can be one or more backwash drainage channels 531; when there are multiple channels, they are arranged at intervals between adjacent filter plates 521. The backwash baffle 532 divides the backwash drainage channel 531 into an upper backwash drainage zone 2 533 and a lower clean water outlet zone 534. The backwash drainage zone 2 533 is connected to the backwash drain outlet 420. On the channel section of the backwash drainage channel 531 corresponding to the clean water outlet zone 534, multiple air distribution holes 535 and multiple clean water inlets 536 are provided. The clean water outlet zone 534 is connected to a clean water outlet pipe 620 and a backwash air pipe 630.

[0037] In some embodiments, refer to Figure 5 The backwash baffle 532 is inclined, and the air distribution holes 535 are evenly distributed along the length of the backwash drainage channel 531. The gas inlet 650 of the backwash air pipe 630 on the pool wall is located above the air distribution holes 535 and close to the high end of the backwash baffle 532. The air distribution holes 535 are divided into near end and far end relative to the gas inlet 650. The far end of the air distribution hole 534 has a longer air intake time than the near end. The inclined arrangement of the backwash baffle 532 can make the filter plate 521 achieve uniform air distribution.

[0038] In some embodiments, refer to Figure 4 The top of the backwash drainage channel 531 is equipped with a V-shaped baffle 537, the vertical middle of which protrudes away from the backwash drainage channel 531. Compared with a flat weir, the V-shaped baffle 537 can prevent filter media particles from directly impacting the weir opening, reducing filter media wear and loss; in addition, the protruding structure is less prone to mud accumulation, making it easier to clean during surface sweeping compared to a flat weir.

[0039] In some embodiments, refer to Figure 5 Multiple water inlets 536 are located at the bottom of the backwash drainage channel 531 and are evenly distributed along its length.

[0040] In some embodiments, refer to Figure 2 , Figure 7 A transition unit 200 is provided between the flocculation reaction unit 100 and the sedimentation unit 300. The transition unit 200 includes a flocculation reaction tank partition plate 211, an inlet rectifier plate 212, and an inlet collection plate 213 arranged vertically in sequence. A water-turning zone 214 is formed between the bottom of the inlet rectifier plate 212 and the bottom of the tank. Multiple sedimentation tank inlet perforations 215 are provided on the inlet collection plate 213, and all of the multiple sedimentation tank inlet perforations 215 are located above the water-turning zone 214. At this time, the sedimentation tank adopts a horizontal pipe sedimentation tank. Multiple sedimentation tank sludge discharge pipes are provided at the bottom of the horizontal pipe sedimentation tank, and multiple horizontal pipe sedimentation devices are provided above the sedimentation tank sludge discharge pipes. The horizontal pipe sedimentation devices are transverse diversion inclined plates. See [reference needed]. Figure 3 In some other embodiments, the flocculation reaction unit 100 is directly connected to the sedimentation unit 300, without a transition unit 200. In this case, the sedimentation device uses an upward-flow inclined plate, as shown in the reference. Figure 9 and Figure 10 .

[0041] The transition unit 200 is a prefabricated component, which is standardized and manufactured in the factory in advance to achieve mass production. The whole process is highly mechanized and efficient. The prefabricated modules are directly transported to the construction site for installation, which greatly shortens the construction cycle and saves time and labor costs.

[0042] In some embodiments, refer to Figure 14 , Figure 17A flocculation baffle 700 is movably installed between the flocculation reaction tank partition 211 and the inlet rectifier plate 212. The flocculation reaction tank partition 211 is provided with a first flocculation outlet 216 and a second flocculation outlet 217. The first flocculation outlet 216 is near the top of the tank, and the second flocculation outlet 217 is near the bottom of the tank. The first flocculation outlet 216 is selectively opened or closed by a first sealing plate 218, and the second flocculation outlet 217 is selectively opened or closed by a second sealing plate 219. The flocculation baffle 700 is set... When the flocculation reaction tank is between the partition 211 and the inlet rectifier plate 212, close the first flocculation outlet 216 and open the second flocculation outlet 217, allowing the water to flow through the second flocculation outlet 217, first over the flocculation partition 700, and then under the inlet rectifier plate 212. When the flocculation partition 700 is removed, open the first flocculation outlet 216 and close the second flocculation outlet 217, allowing the water to flow through the first flocculation outlet 216 and then directly under the inlet rectifier plate 212. When factors affecting the flocculation effect change, such as a drop in temperature or an increase in flow rate, close the first flocculation outlet 216 and open the second flocculation outlet 217. At the same time, move the flocculation partition 700 into the transition zone 200 and fix it to the bottom plate of the transition zone 200. The flocculation path is as follows: Figure 14 As indicated by the arrow, raw water flows out from flocculation outlet 217 and upwards along flocculation baffle 700. After passing over the upper edge of flocculation baffle 700, it flows downwards and then flows under inlet rectifier plate 212. It is then evenly distributed to sedimentation unit 300 through multiple inlet perforations 215 in the sedimentation tank area of ​​inlet collection plate 213. This structure combines the grid flocculation reaction tank and the baffle reaction tank, extending the flocculation reaction path and increasing the flocculation reaction time while maintaining the same volume of the integrated water treatment system, thereby effectively improving the flocculation effect. Simultaneously, the extended flocculation path of the raw water improves the uniformity and stability of water distribution in the width direction of transition unit 200, ensuring efficient operation of sedimentation unit 300. As a specific embodiment, slide rails 710 are provided on both sides of the tank wall between flocculation reaction tank baffle 211 and inlet rectifier plate 212. Flocculation baffle 700 is installed on the slide rails 710 for easy installation and disassembly. Figure 17 .

[0043] In some embodiments, refer to Figure 16 and Figure 19A cylinder 220 is installed on the upper part of the partition plate 211 of the flocculation reaction tank. Limiting rails 221 are installed on both sides of the partition plate 211. The sealing plate 1 218 and sealing plate 219 are a whole plate. The whole plate is provided with an upper opening and a lower opening corresponding to the flocculation outlet 1 216 and flocculation outlet 217. The piston rod of the cylinder 220 is connected to the whole plate and pushes the whole plate to slide along the limiting rails 221. Specifically, when the piston rod of cylinder 220 pushes the plate to align the upper opening with flocculation outlet 216, flocculation outlet 216 opens, the lower opening is offset from flocculation outlet 217, and flocculation outlet 217 closes. When the piston rod of cylinder 220 pushes the plate to align the lower opening with flocculation outlet 217, flocculation outlet 217 opens, the upper opening is offset from flocculation outlet 216, and flocculation outlet 216 closes. In some other embodiments, sealing plate 218 and sealing plate 219 are two independent plates, each driven and controlled by a cylinder.

[0044] In some embodiments, the water collection system includes a shading mechanism 800 for shading the water in the pool area where the sedimentation unit 300, the water collection unit 400, and the filtration unit 500 are located.

[0045] In one specific embodiment, refer to Figure 14 , Figure 15 The shading mechanism 800 includes a drive motor 820, a transmission device, and a drum 830. The transmission device includes a drive sprocket set 840, a driven sprocket set 850, and a chain 860. The drive sprocket set 840 includes a drive sprocket, a drive sprocket support, and a first rotating shaft arranged along the edges of both pool walls. The first rotating shaft spans the pool body, connecting two sets of drive sprockets and is supported by the drive sprocket support. The driven sprocket set 850 includes a driven sprocket, a driven sprocket support, and a second rotating shaft arranged along the edges of both pool walls.

A drum 830 is drivingly connected between the two sets of chains 860, and a shading cloth 870 is wound on the drum 830. (Refer to...) Figure 14 , Figure 15 When the shading mechanism 800 is working, the drive motor 820 drives the roller 830 to rotate via the transmission device, and the shading cloth 870 unfolds, covering the pool area where the sedimentation unit 300, water collection unit 400, and filtration unit 500 are located. (Refer to...) Figure 17 , Figure 18When the flocculation baffle 700 is not used, it is usually placed over the sedimentation unit 300, combined with the flocculation baffle 700, to completely cover the sedimentation unit 300, water collection unit 400, and filtration unit 500. Due to sunlight, water, and residual nutrients in the water, algae growth is easily caused. By using the flocculation baffle 700 and the shade cloth 870 to block sunlight, algae growth on the sedimentation device and filter media surface can be inhibited, effectively reducing the frequency and cost of cleaning and maintenance of the sedimentation device and filter media.

[0046] In some embodiments, refer to Figure 18 The shading mechanism 800 also includes a housing 810, which is arranged along the edges of the two pool walls and across the pool body to house the drive motor 820 and the transmission device, ensuring the safety of each component, extending the life of each component, and ensuring reliable operation.

[0047] In some other embodiments, reference is made to Figure 20 , Figure 21 The shading mechanism 800 is a cover plate 880, which covers the pool area where the sedimentation unit 300, water collection unit 400 and filtration unit 500 are located.

[0048] In some embodiments, the flocculation unit 100 employs a grid flocculation reaction tank.

[0049] In some embodiments, the sedimentation unit 300 is one of a horizontal tube sedimentation tank, an inclined plate sedimentation tank, or an inclined tube sedimentation tank.

[0050] In some embodiments, the filtration unit 500 is one of a standard fast filter, a V-type filter, or a flap valve filter.

[0051] In some embodiments, the plates are made of stainless steel, and the pool body 600 is fixed by welding multiple plates together.

[0052] In some embodiments, refer to Figure 1 Long strips of reinforcing steel 660 are welded to the outer side of the pool wall in both the horizontal and vertical directions. The reinforcing steel 660 provides auxiliary support during the welding process of the plates, making it easier to connect and fix two adjacent plates, while also enhancing the structural strength of the pool wall.

[0053] In some embodiments, the reinforcing steel 660 can be one of H-beams, I-beams, channel steel, or T-beams. As a specific embodiment, the reinforcing steel 660 is a channel steel.

[0054] In some embodiments, the daily water treatment capacity of the tank 600 ranges from 500m³. 3~80000m 3 The volume of the 600 pool ranges from 30m³. 3 ~5500m 3 .

[0055] In some embodiments, the flocculation reaction unit 100, transition unit 200, sedimentation unit 300, water collection unit 400, and filtration unit 500 are located in the following tank areas: flocculation reaction tank area 910, transition zone 920, sedimentation tank area 930, water collection zone 940, and filtration tank area 950, respectively. The area ratio S of the flocculation reaction tank area 910 in the integrated water treatment system is... 絮凝反应池区 =20~30%, the area ratio S of the transition zone 920, sedimentation tank zone 930, and water collection zone 940 in the integrated water treatment system. 沉淀池区 =30~50%, the area ratio of the filter zone in the integrated water treatment system S 滤池区 =30~40%, of which the area of ​​the sedimentation tank area includes the sum of the areas of the transition zone, the sedimentation tank area, and the water collection zone, S 絮凝反应池区 +S 沉淀池区 +S 滤池区 =100%. As a specific embodiment, the area ratio of the flocculation reaction tank zone 910 is 26.0%, the area ratio of the transition zone 920, sedimentation tank zone 930, and water collection zone 940 is 38.0%, and the area ratio of the filter zone 950 is 36.0%.

[0056] In some embodiments, the ratio of the daily water treatment capacity of the tank 600 to the volume occupied by the sedimentation tank 930 is 35-50, and the ratio of the daily water treatment capacity of the tank 600 to the volume occupied by the filter tank 950 is also 35-50. The volume of the sedimentation tank 930 includes the sum of the volumes of the transition zone 920, the sedimentation tank 930, and the water collection zone 940. As a specific embodiment, the ratio of the daily water treatment capacity of the tank 600 to the volume occupied by the sedimentation tank 930 is 42.8, and the ratio of the daily water treatment capacity of the tank 600 to the volume occupied by the filter tank 950 is 42.2, ensuring efficient water purification.

[0057] In some embodiments, the height ratio of the flocculation reaction tank zone 910, the sedimentation tank zone 930, and the filter zone 950 is 10:9:9, and the length ratio of the flocculation reaction tank zone 910, the sedimentation tank zone 930, and the filter zone 950 is 6:38:36. The height of the flocculation reaction tank zone 910 is greater than the heights of the sedimentation tank zone 930 and the filter zone 950. This design, on the one hand, extends the water flow path and flocculation reaction time of the raw water in the flocculation reaction tank zone 910, ensuring thorough mixing of the raw water and flocculant; on the other hand, it maintains sufficient tank height, which helps the water in the flocculation reaction tank zone 910 to flow smoothly into the sedimentation tank zone 930, ensuring the safety and stability of water supply and quality during periods of sudden peak water demand and overloaded production.

[0058] In some embodiments, the volume and shape of the water treatment system can be adjusted as needed, and the system scale can be flexibly adjusted by the number and size of modules to adapt to different water treatment needs. Figure 2 The integrated water treatment system shown is capable of treating 15,000 tons of water per day. Figure 9 The integrated water treatment system shown can process 20,000 tons of water per day. Figure 11 The volume of the integrated water treatment system shown is Figure 2 Twice the size of the structure shown, it can process 30,000 tons of water per day.

[0059] The working process of a water treatment system: Flocculation reaction unit 100: Coagulant is added to the raw water. The coagulant dissolves rapidly in the water. The flocculation reactor 150 causes the water flowing through it to quickly form a vortex, so that the raw water and coagulant react fully and promote the rapid formation of larger and denser flocs from the tiny particles and turbid impurities in the raw water.

[0060] Transition unit 200: The water that has been fully mixed in the flocculation reactor 150 flows out from the flocculation outlet 216 of the partition plate 211 of the flocculation reaction tank and flows from top to bottom, passing under the water inlet rectifier plate 212, and then smoothly enters the sedimentation unit 300 through the water inlet perforation 215 of the sedimentation tank area on the water inlet collection plate 213.

[0061] Sedimentation unit 300: After the water enters the sedimentation unit 300, the flocs in the water are deposited on the sedimentation device 330, fall down onto the mud sliding plate 310 in the sedimentation tank area by gravity, and accumulate in the sludge accumulation area 350 of the sedimentation tank, and are discharged through the sludge discharge pipe 320 in the sedimentation tank area.

[0062] Water collection unit 400: After sedimentation, the water enters the effluent rectification zone 416 through the water through the water through the opening 418 on the effluent collection plate 411, flows over the water weir 412 into the effluent channel 415, and then flows smoothly into the filter unit 500 through the filter zone inlet 419 on the filter zone partition plate 413.

[0063] Filtration unit 500: Water that has been treated by flocculation and sedimentation enters the water distribution channel 511, and is evenly distributed to the top of the filter plate 521 through the water inlet perforation 512 in the filter area of ​​the water distribution channel 511. After being filtered by the filter media, the water flows into the bottom of the filter plate 521 through the filter head 522, and then enters the clean water outlet area 534 through the clean water inlet 536 on the backwash drainage channel 531. Finally, it is output through the clean water outlet pipe 620.

[0064] During the backwashing process, backwashing gas enters the clean water outlet zone 534 through the backwashing air pipe 630. At the same time, backwashing water enters the clean water outlet zone 534 through the clean water inlet 536 and / or the backwashing air pipe 630, passes through the filter head 522 and enters the filter media layer for air and water backwashing. After being cleaned, the wastewater flows over the V-shaped baffle 537 and enters the second backwashing drainage zone 533, and then enters the first backwashing drainage zone 417 through the backwashing drain port 420, and is finally discharged through the backwashing drain pipe 640.

[0065] The above description is only a partial embodiment of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the protection scope of this application.
