[0060] See also Figures 1 to 5This embodiment provides an integrated intelligent and efficient water purification and filtration system, including a raw water pipeline 1, a flocculation component 2, a sedimentation component 3, a first connecting pipeline 5, a filtration component 4, a second connecting pipeline 6, and a water storage tank. A booster pump and a static mixer are sequentially installed on the raw water pipeline 1. The static mixer is used to mix the coagulant with the raw water, and the raw water pipeline 1 is used to transport the raw water. The flocculation component 2 includes a flocculation box 21, a set of flocculation meshes 22, and multiple flocculation grids 23. These multiple flocculation grids 23 are distributed in a first preset manner within the flocculation box 21. The flocculation grid 23 divides the flocculation box 21 into a collection chamber 212 and multiple flocculation chambers 211. Each flocculation grid 23 is provided with a flow hole 231. Multiple flocculation chambers 211 are connected in sequence through the flow hole 231. The collection chamber 212 is connected to the last flocculation chamber 211. There are multiple flocculation grid groups 22. Each flocculation grid group 22 is set in a flocculation chamber 211. The flocculation grid group 22 includes multiple flocculation grids 22 spaced apart in the vertical direction. The first flocculation chamber 211 is connected to the output end of the raw water pipeline 1.

[0061] The sedimentation assembly 3 includes a sedimentation tank 32 and an inclined tube assembly 31. The sedimentation tank 32 has a sedimentation chamber. The inclined tube assembly 31 is disposed inside the sedimentation tank 32 to divide the sedimentation chamber into a first sedimentation chamber 321 and a second sedimentation chamber 322 distributed from bottom to top. The first sedimentation chamber 321 is connected to the collecting chamber 212, and the second sedimentation chamber 322 is connected to the first sedimentation chamber 321 through the inclined tube assembly 31. A first outlet 323 is provided above the second sedimentation chamber 322. A first connecting pipe 5 is connected to the first outlet 323. The filtration assembly 4 includes a filter box 41, a filter media layer 42, a filter tube assembly 43, and a partition layer 44. The filter box 41 has a filter chamber, and the partition layer 44 is disposed inside the filter media layer 321. Inside the filter housing 41, the filter chamber is divided into a first filter chamber and a second filter chamber 413 distributed from bottom to top. The first filter chamber is provided with a filter material layer 42, which divides the first filter chamber into a first upper chamber 411 and a first lower chamber 412. The filter tube assembly 43 is used to connect the first lower chamber 412 and the second filter chamber 413. The first upper chamber 411 is connected to the first connecting pipe 5. A second output port 414 is provided above the second filter chamber 413. The second connecting pipe 6 is connected to the second output port 414. A slow-release disinfection dosing device is provided at the output end of the second connecting pipe 6. A water storage tank is connected to the second connecting pipe 6 and is used to store purified water.

[0062] In this embodiment, raw water pipeline 1 can be understood as a pipeline used to transport raw water. The booster pump can be a water pump used to transport the raw water upwards against gravity. A static mixer is installed at the outlet of raw water pipeline 1. The static mixer can fully mix the coagulant with the raw water. Specifically, the coagulant is added via a water jet injector, achieving initial mixing with the raw water, and then enters the static mixer. The coagulant is fully diffused in the water, creating favorable conditions for subsequent coagulation reactions. The static mixer has the advantages of low resistance and high efficiency, which can save on the amount of coagulant used.

[0063] The flocculation component 2 includes a flocculation box 21, a set of flocculation grids 22, and a flocculation grille 23. The flocculation box 21 and the sedimentation box 32 can be arranged adjacent to each other. It should be noted that multiple flocculation grilles 23 are provided inside the flocculation box 21. The flocculation grilles 23 divide the flocculation box 21 into multiple flocculation chambers 211 and a collection chamber 212. Each flocculation chamber 211 is connected sequentially, and the collection chamber 212 is connected to the last flocculation chamber 211. Specifically, the connection method is that there is one and only one flow hole 231 on the flocculation grille 23, and the height of the flow hole 231 can be adjusted according to actual needs. One feasible configuration is as follows: the flow holes 231 of two adjacent flocculation grids 23 are staggered. When raw water passes through the first flocculation chamber 211, if the flow holes 231 are at the top, the raw water will first fill the first flocculation chamber 211 and then enter the second chamber through the flow holes 231; if the flow holes 231 are at the bottom, the raw water will first fill the second flocculation chamber 211 and then continue to fill the first flocculation chamber 211. The specific filling order varies depending on the distribution of the flow holes 231. It can be understood that the raw water gradually fills multiple flocculation chambers 211 in a connected order. During the filling process, the coagulant and raw water are fully mixed due to the flocculation grids 22. The interaction between the water flow and the flocculation grids 22 provides thorough stirring, allowing the coagulant to flocculate impurities in the raw water, producing uniform and coarse flocs. Finally, when the raw water reaches the collection chamber 212, the flocculation reaction between the coagulant and the raw water is complete, and the raw water then enters the sedimentation tank 32 through the collection chamber 212.

[0064] The flocculation component 2 shown in this embodiment adopts a combination of reciprocating baffles and grids, which can reduce flocculation time, and the head loss of grid flocculation is small and space is saved. In order not to reduce head loss, the last two layers of water flow in the same direction. The total flocculation reaction time is only 6 to 15 minutes (in order to improve the shock load resistance of the flocculation reaction cylinder, the actual design reaction time t = 15 to 20 minutes) to form flocs, and the water production can be increased by 100%. Impurities in the water are reacted to form uniform and coarse flocs, which facilitates subsequent solid-liquid separation.

[0065] The sedimentation assembly 3 includes a sedimentation tank 32 and an inclined tube assembly 31. The sedimentation tank 32 includes a first sedimentation chamber 321 and a second sedimentation chamber 322, arranged from bottom to top. The inclined tube assembly 31 is provided between the first sedimentation chamber 321 and the second sedimentation chamber 322. The inclined tube assembly 31 can separate impurities and water in the first sedimentation chamber 321, thereby causing sludge to settle at the bottom of the first sedimentation chamber 321. The first sedimentation chamber 321 is connected to the collection chamber 212. Specifically, the connection can be achieved by having multiple holes on the side wall of the collection chamber 212, through which water containing impurities can directly enter the first sedimentation chamber 321. The water gradually passes through the inclined tube assembly 31 into the second sedimentation chamber 322 in the first sedimentation chamber 321, and then exits through the first outlet 323 on the second sedimentation chamber 322. Optionally, the first outlet 323 is provided with a water outlet weir to further block the foam in the second sedimentation chamber 322 and improve the purity of the water in the first outlet 323.

[0066] In this embodiment, the sedimentation component 3 adopts a vertical flow sedimentation method, which is beneficial for saving space. The water after flocculation rises to the second sedimentation chamber 322, where the flocs in the water settle in the inclined tube assembly 31, achieving solid-liquid separation. The upward flow velocity within the sedimentation tank 32 is approximately 2.0–4.0 mm / s. The inclined tube assembly 31 uses honeycomb inclined tube packing, effectively improving sedimentation efficiency. The turbidity of the settled water is below 10 degrees, reducing the burden on the filter and saving backwash water.

[0067] In this embodiment, the filter assembly 4 includes a filter housing 41, a filter media layer 42, a filter tube assembly 43, and a partition layer 44. The partition layer 44 divides the filter housing 41 into a first filter chamber and a second filter chamber 413 arranged from bottom to top. The first filter chamber is provided with a filter media layer 42, which further divides the first filter chamber into a first upper chamber 411 and a first lower chamber 412. The first connecting pipe 5 enters the first upper chamber 411, so the water flow wets the filter media layer 42 under its own weight and seeps out from the gaps in the filter media layer 42 to reach the first lower chamber 412. The first lower chamber 412 and the second filter chamber 413 are connected through the filter tube assembly 43, which includes multiple filter tubes. When the first lower chamber 412 is full, the water pressure will force the water in the first lower chamber 412 into the filter tube assembly 43 and reach the second filter chamber 413, thereby improving the filtration efficiency and reducing the number of backwashing times.

[0068] In this embodiment, the filter housing 41 is a gravity-type valveless filter. After sedimentation, the effluent is filtered through the filter media layer 42. Residual flocs in the water are retained by the filter media layer 42, ensuring that the effluent turbidity is below 1 degree. The filter media layer 42 can be made of homogeneous quartz sand with a diameter of φ0.9~φ1.4 and K80<1.5, with a filtration rate of approximately 9~11m / h, a backwash intensity of 12~16L / (m2·s), a backwash time of 4~6 minutes, and a system termination filtration head of 1.7m. Automatic backwashing is performed based on hydraulic principles, and the backwash intensity and time are basically the same each time, featuring stable and reliable operation and convenient management.

[0069] In this embodiment, a slow-release disinfection dosing device is installed on the second connecting pipe 6. After the filtered water is doped with disinfectant through the slow-release disinfection dosing device, it flows into the water storage tank, where the water is clean water. The disinfectant is chlorine tablets, and the amount of disinfectant added is controlled by adjusting the flow rate of water passing through the chlorination tank to ensure that the effluent water quality meets drinking water standards.

[0070] This embodiment integrates a raw water pipeline 1, a flocculation assembly 2, a sedimentation assembly 3, a filtration assembly 4, and a water storage tank to form a highly efficient water treatment process. Raw water enters the flocculation assembly 2 via a booster pump and a static mixer. Coagulant is evenly added to the static mixer and thoroughly mixed with the raw water. The water then flows through multiple partitioned flocculation chambers 211, enhancing the flocculation effect and forming larger flocs. Next, the water flows into the sedimentation assembly 3, where, with the help of inclined tubes 31, the flocs settle in the sedimentation chamber, separating out impurities. After sedimentation, the water flows into the filtration assembly 4, where the filter media layer 42 removes remaining impurities, ensuring water purity. Finally, after disinfection, the purified water is stored in the water storage tank. This technical solution uses a unidirectional flow distribution method in the flocculation component 2 to reduce head loss. The inclined tube group 31 is used to make the water flow from bottom to top into the filter component 4. The filter component 4 further utilizes the height difference to make the water flow fall into the first filter chamber by its own weight, and then enters the second filter chamber 413 through the pressure difference. It makes full use of the gravitational potential energy of the water flow, reduces equipment power consumption, improves water treatment efficiency, enhances water quality safety, and has an integrated design that saves space and adapts to the water purification needs of different environments.

[0071] See also Figure 3 and Figure 4In some embodiments, the flocculation assembly 2 further includes a first inclined guide plate group 24 and a first drain pipe group 25. The first inclined guide plate group 24 includes a plurality of first inclined guide plates 24, and a first inclined guide plate 24 is provided at the bottom of each flocculation chamber 211. The first inclined guide plates 24 are inclined at a certain angle to the bottom of the flocculation box 21. The first drain pipe group 25 includes a plurality of first drain pipes 25, and the number of first drain pipes 25 corresponds to the number of first inclined guide plates 24. The first drain pipes 25 are provided at the bottom of the flocculation chamber 211 and are used to discharge impurities in the flocculation chamber 211 to the outside.

[0072] In this embodiment, the first inclined guide plate 24 is an inclined flat plate installed at the bottom of the flocculation chamber 211, with an inclination angle typically between 15 and 45 degrees. Its function is to guide the flocs to settle and improve the settling efficiency. The first drain pipe 25 is a drain pipe installed at the bottom of the flocculation chamber 211, corresponding one-to-one with the number of the first inclined guide plates 24. The first drain pipe 25 is used to discharge the settled impurities and flocs.

[0073] This embodiment improves the flocculation and wastewater discharge process by introducing a first set of inclined guide plates 24 and a first set of drain pipes 25. Specifically, the first set of inclined guide plates 24 consists of multiple first inclined guide plates 24, which are inclined at the bottom of each flocculation chamber 211, forming a certain angle with the bottom of the flocculation box 21. This design allows the settled flocs to slide smoothly to the bottom of the flocculation chamber 211 during the flocculation process, thus concentrating at the inlet of the drain pipe. The first drain pipe 25, corresponding to each first inclined guide plate 24, is located at the bottom of the flocculation chamber 211, effectively collecting and discharging the settled impurities and flocs. When the impurities in the flocculation chamber 211 settle to a certain extent, they can be discharged out of the system by controlling the opening and closing of the drain pipe. This design not only improves the efficiency of the flocculation process but also reduces the residence time of flocs in the flocculation chamber 211, avoiding secondary pollution and floc resuspension.

[0074] See also Figure 3 In some embodiments, the flow holes 231 of two adjacent flocculation grids 23 are staggered. This makes the flow path of water in multiple flocculation chambers 211 more complex, which facilitates the coagulant and water to mix fully under the action of the flocculation grid 22 to form flocs.

[0075] See also Figure 3 and Figure 4In some embodiments, the sedimentation assembly 3 further includes a second set of drain pipes 34 and a plurality of second inclined guide plates 33. The plurality of second inclined guide plates 33 are sequentially arranged at the bottom of the first sedimentation chamber 321. Each set of second inclined guide plates 33 includes two second inclined guide plates 33. The second inclined guide plates 33 are inclined at a certain angle to the bottom of the sedimentation tank 32. The two second inclined guide plates 33 in the same set are arranged in a V-shape. The set of second drain pipes 34 includes a plurality of second drain pipes 34. The number of second drain pipes 34 corresponds to the number of second inclined guide plates 33. Each second drain pipe 34 is arranged between two second inclined guide plates 33 in the same set. The second drain pipes 34 are used to discharge impurities in the first sedimentation chamber 321 to the outside.

[0076] In this embodiment, multiple sets of second inclined guide plates 33 are sequentially arranged at the bottom of the first sedimentation chamber 321, with each set including two second inclined guide plates 33. The second inclined guide plates 33 are inclined at a certain angle to the bottom of the sedimentation tank 32, typically between 15 and 30 degrees. This design allows the settled impurities to be better guided to the inlet of the drain pipe. The two second inclined guide plates 33 in the same set are arranged in a V-shape, forming a concentrated sedimentation zone, enhancing the aggregation effect of flocs and promoting sedimentation efficiency. The number of sets of second drain pipes 34 corresponds to the number of sets of second inclined guide plates 33, with each second drain pipe 34 positioned between two second inclined guide plates 33 in the same set. The second drain pipes 34 are used to discharge the impurities and sediments accumulated in the first sedimentation chamber 321 to the outside, ensuring smooth water flow within the chamber and preventing siltation.

[0077] When water flows through the sedimentation assembly 3, the flocs begin to settle in the first sedimentation chamber 321. The design of the second inclined guide plate 33 causes the settled flocs to concentrate at the bottom of the second inclined guide plate 33 due to gravity, and eventually gather near the second drain pipe 34 between the second inclined guide plates 33 in the same group. Due to the V-shaped arrangement, the sediment forms a denser area, increasing the sedimentation speed. As the sediment gradually increases, the second drain pipe 34 is opened, and the settled impurities are quickly discharged, preventing them from being resuspended in the first sedimentation chamber 321, maintaining the stability and cleanliness of the water. This process can be timed or automatically controlled as needed to ensure optimal sludge discharge.

[0078] This embodiment enhances floc aggregation and promotes the sedimentation process by using a V-shaped second inclined guide plate 33, significantly improving sedimentation efficiency; timely discharge of sediment reduces the concentration of impurities in the water, ensuring stable and reliable effluent quality; and the effective sewage discharge design reduces sediment accumulation in the sedimentation chamber, thereby reducing the frequency of cleaning and maintenance and alleviating the burden of manual operation.

[0079] See also Figure 2In some embodiments, the inclined tube group 31 includes multiple inclined tubes, which are distributed in a honeycomb pattern. The inclined tubes are inclined at a certain angle to the sedimentation tank 32, and the first sedimentation chamber 321 and the second sedimentation chamber 322 are connected through the inclined tubes.

[0080] In this embodiment, multiple inclined tubes are arranged in a honeycomb pattern, forming a regular hexagonal network structure. The inclined tubes can also be made into hexagonal structures to improve sedimentation efficiency. The inclined tubes are tilted at a certain angle to the sedimentation tank 32, typically between 45 and 60 degrees, with the angle selected based on the optimal sedimentation effect. During use, water flows through the honeycomb-shaped inclined tubes, forming sedimentation channels inside the tubes. Suspended particles settle more quickly under the influence of gravity and the tilt angle of the inclined tubes.

[0081] In this embodiment, the honeycomb structure increases the sedimentation contact area, shortens the particle settling distance, and improves sedimentation efficiency and separation accuracy, with sedimentation efficiency increased by 30%-50%. The reasonable honeycomb arrangement reduces water flow resistance, ensures smooth water flow, reduces system energy consumption, and reduces system maintenance frequency.

[0082] See also Figure 2 and Figure 5 In some embodiments, the filter assembly 4 further includes a third connecting pipe 7, which has a first end and a second end. The third connecting pipe 7 is connected to the first connecting pipe 5, and the connection between the first connecting pipe 5 and the third connecting pipe 7 is located near the first end. The first end penetrates the partition layer 44 and is connected to the first upper chamber 411. The second end is connected to the outside, and the height of the second end is lower than the height of the first end.

[0083] In this embodiment, when the water purification system is running, water flows through the filter assembly 4 and, through its connection with the third connecting pipe 7, is guided to the first upper chamber 411 during the filtration process. The design of the first end allows water to enter the first upper chamber 411 at this location for preliminary water treatment. The second end connects to the outside and is positioned at a lower location, effectively discharging excess water or air. Due to the low position of the second end, backflow of water within the pipe is prevented, ensuring that water flows only towards the first upper chamber 411 without backflow.

[0084] Furthermore, the design of the third connecting pipe 7 facilitates the timely discharge of backwash wastewater from the filter housing 41 during the backwashing process, thereby improving drainage efficiency.

[0085] See also Figure 2 and Figure 5In some embodiments, the filter assembly 4 further includes a siphon tube group 8, which includes a first siphon branch tube 81, a second siphon branch tube 82, and a siphon main tube 83. The siphon main tube 83 is connected to the first siphon branch tube 81 and the second siphon branch tube 82 respectively. One end of the first siphon branch tube 81 is connected to the second filter chamber 413, and the other end of the first siphon branch tube 81 is connected to the third connecting pipe 7. One end of the siphon main tube 83 is connected to the third connecting pipe 7, and the other end of the siphon main tube 83 is connected to the outside. One end of the second siphon branch tube 82 is connected to the siphon main tube 83, and the other end of the second siphon branch tube 82 is connected to the outside.

[0086] The siphon assembly 8 consists of a first siphon branch pipe 81, a second siphon branch pipe 82, and a main siphon pipe 83, forming a complex yet efficient drainage system. One end of the first siphon branch pipe 81 connects to the second filter chamber 413, and the other end connects to the third connecting pipe 7. One end of the main siphon pipe 83 also connects to the third connecting pipe 7, and the other end leads to the outside. One end of the second siphon branch pipe 82 connects to the main siphon pipe 83, and the other end leads directly to the outside. This design creates a unique water flow guidance and discharge system. During backwashing, when the filter media layer 42 inside the filter housing 41 needs to be cleaned, the water flow reverses from top to bottom through the filter media layer 42, washing away accumulated impurities. The first siphon branch pipe 81 and the main siphon pipe 83 work together to quickly guide the wastewater generated during backwashing to the outside for discharge. The second siphon branch pipe 82 provides an additional drainage channel, ensuring a smooth and efficient drainage process.

[0087] The unique design of the siphon assembly 8 utilizes the siphon principle, achieving rapid and efficient drainage through differences in pipe height and water pressure. The connection design between the first siphon branch pipe 81 and the main siphon pipe 83 allows wastewater to be discharged quickly, avoiding blockages and stagnation problems that may occur in traditional drainage systems. Simultaneously, the presence of the second siphon branch pipe 82 further enhances the redundancy and reliability of the drainage system, improving the drainage efficiency of the backwashing process. Through a carefully designed pipe layout, wastewater within the filter housing 41 can be quickly discharged in the shortest possible time, reducing the time and water volume required for backwashing.

[0088] In some embodiments, the filter media layer 42 contains homogeneous quartz sand with a diameter of φ0.9 to φ1.4 and a K80 < 1.5.

[0089] In some embodiments, the outer surface of the flocculation tank 21 and / or sedimentation tank 32 and / or water storage tank is also provided with a thermal insulation layer. This allows it to adapt to different outdoor environments and ensures the normal operation of the entire system in low-temperature environments.

[0090] In some embodiments, the wall thickness of the flocculation tank 21 and / or sedimentation tank 32 and / or water storage tank is not less than 6 mm; and / or, the bottom plate thickness of the flocculation tank 21 and / or sedimentation tank 32 and / or water storage tank is not less than 8 mm.

[0091] Unlike existing technologies, the integrated intelligent and efficient water purification and filtration system provided by the above technical solution integrates a raw water pipeline 1, a flocculation component 2, a sedimentation component 3, a filtration component 4, and a water storage tank to form a highly efficient water treatment process. Raw water enters the flocculation component 2 via a booster pump and a static mixer. Coagulant is evenly added in the static mixer and thoroughly mixed with the raw water. The water then flows through multiple partitioned flocculation chambers 211, enhancing the flocculation effect and forming larger flocs. Next, the water flows into the sedimentation component 3, where, with the help of inclined tubes 31, the flocs settle in the sedimentation chamber, separating out impurities. After sedimentation, the water flows into the filtration component 4, where the filter media layer 42 removes remaining impurities, ensuring water purity. Finally, after disinfection, the purified water is stored in the water storage tank. This technical solution uses a unidirectional flow distribution method in the flocculation component 2 to reduce head loss. The inclined tube group 31 is used to make the water flow from bottom to top into the filter component 4. The filter component 4 further utilizes the height difference to make the water flow fall into the first filter chamber by its own weight, and then enters the second filter chamber 413 through the pressure difference. It makes full use of the gravitational potential energy of the water flow, reduces equipment power consumption, improves water treatment efficiency, enhances water quality safety, and has an integrated design that saves space and adapts to the water purification needs of different environments.
