Description

A standardized, low-carbon, modular water purification system Technical Field

[0001] The present invention belongs to the technical field of surface water treatment, and in particular relates to a standardized, low-carbon, modular water purification system. Background Art

[0002] Surface water refers to water bodies on land, most of which are formed by surface runoff from natural precipitation, glacier meltwater and springs. Currently, due to the increasing frequency of extreme climate events around the world, the frequency of wildfires and acid rain has also increased, causing excessive alkaline or acidic wastewater to flow into surface runoff, resulting in excessive acidification or alkalization of surface water. In addition, large-scale input of chemical fertilizers can also lead to excessive acidification or alkalization of surface water.

[0003] In traditional water purification methods, the process of treating over-acidified or alkaline surface water generally uses steps such as flocculation, sedimentation, filtration and disinfection; in some specific environments (for example: remote villages with power shortages, arid areas with water shortages, underdeveloped areas with incomplete infrastructure, etc.), the traditional water purification process requires the use of flocculation tanks, sedimentation tanks and filtration tanks that occupy a large space, which requires high construction costs and takes a long time to treat. In addition, during the flocculation process, high-power stirring equipment is required to fully stir the drugs and the surface water to be treated. Therefore, the water purification efficiency, universality and economy of the existing water purification methods are low.

[0045] The embodiments of the present invention provide a standardized, low-carbon, modular water purification system to solve the problems existing in the prior art.

[0046] Referring to Figure 1, a standardized, low-carbon, modular water purification system is shown, and its hardware structure is composed of three stacked layers. Among them, the first layer of the water purification system of the present invention is the top layer, and the top layer is provided with a closed clean water storage cylinder 20, and the closed clean water storage cylinder 20 is used to store the clean water produced by the water purification system. The second layer of the water purification system of the present invention is the middle layer, and the middle layer is provided with a vortex water purification processor 21, and the vortex water purification processor 21 is used to fully react surface raw water and chemical agents to obtain once-treated raw water. The third layer of the water purification system of the present invention is the bottom layer, and the bottom layer is provided with a multifunctional water cylinder 22, and the multifunctional water cylinder 22 is equipped with a triangular weir partition 14 to separate the balance area 15 and the multi-layer medium filtration area 13. The balance area 15 is used for external surface raw water, and the multi-layer medium filtration area 13 is used to receive the once-treated raw water and filter it. The filtered water is then sent to the disinfection through a preset valve body and then transported to the top layer.

[0047] Compared with the existing technology, the present invention adopts a standardized, layered, modular integrated design, which can maximize the reduction of the footprint of the water purification system, thereby solving the problems existing in the existing technology.

[0048] Referring to Figures 1-4 , the multifunctional water tank 22 has a first water inlet 27 at the top of the left side wall of the balancing area 15. A raw water outlet 28 is also defined at the bottom of the left side wall of the multifunctional water tank 22. This allows the balancing area 15 of the multifunctional water tank 22 to receive raw water through the first water inlet 27 and to discharge it through the raw water outlet 28 when excess raw water is present. The multifunctional water tank 22 is located within the multilayer media filtration area 13 and is equipped with a sprinkler module 8, a multilayer media filter assembly 11, and a wedge-shaped steel wire filter tube 12. A filtrate outlet 38 is defined on the right side wall of the multilayer media filtration area 13 for discharging filtered water. The sprinkler module 8 is located directly above the multilayer media filtration area 13. The multilayer media filter assembly 11 is located within the multifunctional water tank 22. The wedge-shaped steel wire filter tube 12 is located at the bottom of the multilayer media filtration area 13 and is connected to the filtrate outlet 38.

[0049] Among them, water level sensors are provided in the balance area 15 of the multifunctional water tank 22 and the closed purified water storage tank 20 to detect the liquid level conditions in the corresponding areas. Through the preset over-water level control system, waste caused by water overflowing out of the tank due to excessively high water levels can be avoided.

[0050] Compared to existing technologies, surface water is collected from the source through a first water inlet 27 and then transported to a rectangular balancing area 15 located on the left side of the system's bottom floor. This balancing area 15 receives and stores the surface water and also balances the incoming water. Below the first water inlet 27 is a raw water outlet 28 for emergency or cleanup needs.

[0051] Referring to Figures 1-6, the vortex water purification processor 21 is arranged above the multi-layer media filtration area 13. The vortex water purification processor 21 is provided with a water treatment reaction unit 4, an equipment control area 41, and an ultraviolet disinfection module 25. The shell of the water treatment reaction unit 4 is internally connected. The upper portion of the shell of the water treatment reaction unit 4 is hollow cylindrical, and the lower portion of the shell of the water treatment reaction unit 4 is hollow inverted conical. The upper portion of the shell of the water treatment reaction unit 4 is provided with a second water inlet 43 for receiving raw water from the balancing area 15. The second water inlet 43 is connected to the automatic injection subsystem through a preset pipeline.

[0052] As shown in Figure 3, the automatic injection subsystem includes multiple medicine barrels 18, each equipped with an independent injection device for pumping out the chemicals within the barrels 18. The barrels 18 can be configured as needed to automatically inject chemicals such as coagulants, flocculants, and acid-base regulators into the water inlet pipe. For example, organic flocculants and organic coagulants can assist in the purification process. These chemicals can aggregate pollutants or suspended solids in the water into large flocs, allowing the pollutants to settle more quickly. Organic coagulants and flocculants, as degradable chemicals, can prevent secondary contamination of purified water. Chemicals such as Tanflux and chitosan are preferred as additives.

[0053] As shown in Figures 1, 5, and 6, a first water inlet pipe 6 is provided within the balancing area 15 of the multifunctional water tank 22. The first water inlet pipe 6 is connected to a first delivery pump 33, the outlet of which is connected to a second water inlet pipe 42, which is connected to a second water inlet 43. A first injection port 34 is provided at the elbow of the first water inlet pipe 6, a second injection port 10 is provided at the elbow of the second water inlet pipe 42, and a third injection port is provided at the outlet of the second water inlet pipe 42. The first injection port 34, the second injection port 10, and the third injection port are connected to the outlet of the injection device. Static mixing blades are provided within the vertical pipe of the second water inlet pipe 42. As water flows through, the static mixing blades rotate, ensuring that the added chemicals are fully mixed with the surface raw water without the intervention of an external agitator.

[0054] As shown in Figure 3, the equipment control area 41 is located adjacent to one side of the water treatment reactor 4. The chemical solution tank 18 is located in the center of the equipment control area 41, the first delivery pump 33 is located at the lower left of the equipment control area 41, the equipment control module 19 is located above the chemical solution tank 18, and the pre-set second delivery pump 32 and ultraviolet disinfection module 25 are located at the lower right of the equipment control area 41. The ultraviolet disinfection module 25 and the equipment control module 19 are both located within the equipment control area 41.

[0055] Preferably, the first delivery pump 33 can be a high-efficiency, low-power-consumption brushless motor centrifugal pump.

[0056] Compared with the prior art, the system of the present invention uses a first delivery pump 33 to pump raw water from the first water inlet pipe 6 in the balancing area 15 through the second water inlet pipe 42 and then into the vortex water purification processor 21. A first injection port 34 is provided at the elbow position of the first water inlet pipe 6, and a second injection port 10 is provided at the elbow position of the second water inlet pipe 42. The third injection port can be used at the beginning position of the second water inlet pipe 42 as needed. When water passes through the elbow, the water flow state in the water pipe will change from laminar flow to turbulent flow, so that the raw water and the agent can be fully mixed without the action of external force.

[0057] 1 and 2 , the water purification system of the present invention further includes a sludge dewatering bag 17 , a sludge discharge port is provided at the bottom of the lower outer shell of the water treatment reaction unit 4 , a grid 16 is provided above the balancing area 15 , and the sludge dewatering bag 17 is placed on the grid 16 , and the sludge discharge port is connected to a sludge discharge valve 30 .

[0058] Compared with the prior art, the water purification system of the present invention can discharge the sludge in the water treatment reaction part 4 through the sludge discharge pipe 29 to the sludge dewatering bag 17 for sludge dewatering treatment by controlling the sludge discharge valve 30. The residual filtrate seeps out of the sludge dewatering bag 17 and flows back to the balancing area 15 for secondary treatment. The solid sludge in the sludge dewatering bag 17 can be discarded or reused.

[0059] Referring to Figures 1-7, the enclosed clean water storage tank 20 is located atop the vortex water purifier 21. It is equipped with a water intake 23 for accessing clean water, a clean water inlet 40, and a backwash subsystem for backwashing the multi-layer media filter assembly 11. The clean water inlet 40 is connected to the filtrate discharge port 38 via a pre-set valve. When the pre-set valve opens the corresponding channel, filtered water from the multi-layer media filter area 13 is pumped into the enclosed clean water storage tank 20 for storage. The clean water inlet 40 is also connected to the ultraviolet disinfection module 25, ensuring that the filtered water is disinfected by ultraviolet light during its pumping into the enclosed clean water storage tank 20.

[0060] As shown in Figures 4, 5, and 7, the closed clean water storage cylinder 20 is provided with a backwash liquid discharge port 1. The backwash subsystem includes an electric three-way valve 9 and a backwash liquid discharge pipe 5. The first port of the electric three-way valve 9 is connected to the filtrate discharge port 38. The second port of the electric three-way valve 9 is connected to the backwash liquid discharge pipe 5. The third port of the electric three-way valve 9 is connected to the second water outlet pipe 24. The second water outlet pipe 24 is connected to the second delivery pump 32 and then to the water inlet of the ultraviolet disinfection module 25. The water outlet of the ultraviolet disinfection module 25 is connected to the clean water inlet 40 of the closed clean water storage cylinder 20.

[0061] Preferably, the second delivery pump 32 can be a high-efficiency, low-power-consumption brushless motor centrifugal pump.

[0062] 3 , 4 and 5 , the clean water inlet 40 is opened at the upper front side of the closed clean water storage cylinder 20 , the water intake 23 is opened at the bottom middle position of the side of the closed clean water storage cylinder 20 , and the backwash liquid discharge port 1 is opened relative to the water intake 23 .

[0063] Compared with the prior art, the multi-layer media filter assembly 11 is a multi-layer design, and different media materials can be selected for different filter layers as needed, such as sand, stone, coconut shell, activated carbon and other media of different coarseness and fineness. The wedge-shaped steel wire filter tube 12 is laid at the bottom of the filter assembly. The wedge-shaped steel wire filter tube 12 collects and aggregates the filtered water through the pores around the tube. When the filtrate is discharged, the electric three-way valve 9 will connect the filtrate discharge port 38 and the channel of the second water outlet pipe 24. The filtrate is pumped from the wedge-shaped steel wire filter tube 12 and the second water outlet pipe 24 to the ultraviolet disinfection module 25 for disinfection through the second delivery pump 32. At the same time, the clean water that has completed the disinfection treatment will be transferred to the closed clean water storage cylinder 20 for storage. When the water purification system of the present invention is backwashing, the electric three-way valve 9 will connect the channel between the filtrate discharge port 38 and the backwash liquid discharge pipe 5, and the water in the sealed water purification tank will flow out from the backwash liquid discharge port 1. The backwash liquid will quickly flow into the wedge-shaped steel wire filter tube 12 at the bottom of the multi-layer medium filter area 13 through the backwash liquid discharge pipe 5 under its own gravity. The backwash liquid will wash away the pollutants accumulated in the multi-layer medium filter assembly 11 from bottom to top, and the pollutants will be carried to the top of the multi-layer medium filter area 13 with the rising water flow. The backwash wastewater will be controlled to flow back to the balance cylinder through the triangular weir on the triangular weir partition 14 for secondary treatment.

[0064] 6, 7 and 8, a water tray 35 is provided at the top of the water treatment reaction unit 4 for receiving clarified water after solid-liquid separation in the funnel separator 3, and the water tray 35 is connected to the transfer tray 37. The water treatment reaction unit 4 is equipped with an impact nozzle 2, which is arranged close to the second water inlet 43. The nozzle will be used to improve the fluidity of the water flow inside the vortex water purification processor 21 to ensure that the water flow does not stagnate. The funnel separator 3 is in the shape of a hollow truncated cone. When the water flow enters the water treatment reaction unit 4, the route and time of the water flow can be extended. At the same time, the heavier suspended solids that hit the surface of the funnel separator 3 can be precipitated to the bottom of the water treatment reaction unit 4 along the inclined surface. The drain pan 35 is rectangular in shape, with a circular hole at its center and a hollow cylinder at its bottom. The tops of the stacked funnel separators 3 are connected to the hollow cylinder. After sedimentation and solid-liquid separation, the water flows through the gaps between the stacked funnel separators 3 to the center, overflowing from the circular opening at the top into the drain pan 35, and then from there to the transfer tray 37. A pH detection probe and a water level sensor are located at the center of the drain pan 35 to monitor the pH and water level of the water in the drain pan 35.

[0065] Preferably, the water purification system of the present invention can automatically inject an acid-base regulator through a corresponding system to ensure that the pH value of the purified water meets the standard.

[0066] 9 and 10 , the main pipe of the sprinkler module 8 is rectangular with rounded corners and is provided with a plurality of micropores, which are positioned directly above the multi-layered media filter area 13 . The main pipe of the sprinkler module 8 is connected to the first water outlet 39 of the central rotating disk 37 .

[0067] The workflow and principle of the present invention are as follows:

[0068] First, connect the pipeline of the external raw water delivery pump from the water source to the first water inlet 27 of the balancing area 15, and pump the untreated surface water from the water source into the balancing area 15 through the raw water delivery pump for the first step of balancing treatment. When the liquid level gauge in the balancing area 15 senses that there is a certain amount of untreated water in the balancing area 15, the first delivery pump 33 starts and starts to run, and pumps the untreated raw water to the water treatment reaction part 4 through the first water inlet pipe 6 and the second water inlet pipe 42. At the same time, the automatic drug injection subsystem will also start to run, and the drug injection device of the drug barrel 18 will start to pump the drug to the first drug injection port 34, the second drug injection port 10 and the third drug injection port respectively.

[0069] The user can mix appropriate chemicals, such as coagulants, flocculants, and pH regulators, in different chemical tanks 18 as needed. If biodegradable organic chemicals such as organic flocculants and organic coagulants are used, such as Tanflux and chitosan, secondary contamination of the purified water can be avoided.

[0070] As water passes through the elbow, the flow inside the pipe changes from laminar to turbulent. As the chemical is injected into the elbows of each inlet pipe, the turbulent flow allows for thorough mixing of the raw water and chemical without the need for external forces. Because static mixing blades are incorporated into the vertical pipe of the second inlet pipe 42, the impact of the water on these blades also causes the flow to become turbulent, promoting secondary mixing of the raw water and chemical.

[0071] The raw water after being fully mixed with the reagent will enter the water treatment reaction part 4 through the second water inlet 43. The impact nozzle 2 in the water treatment reaction part 4 will push the water to move along the circular edge in the reaction part, so that the water in the water treatment reaction part 4 will flow in a rotational manner, thereby improving the water flow inside the water purifier and ensuring that the water flow will not stagnate.

[0072] The center of the water treatment reaction part 4 is provided with a multi-layer vertically stacked conical funnel separator 3. The funnel separator 3 is a hollow truncated cone design, which helps to extend the route and time of water flow when the water flows into the water treatment reaction part 4. As time goes by, the impurity particles in the raw water are gradually adsorbed by the flocculant, and the volume and mass of the flocs also increase. When the flocs touch the funnel separator 3 during the rotation process, their movement trajectory will change, and the heavier suspended solids will settle to the water treatment reaction part 4 along the inclined surface of the funnel separator 3. Silt accumulates at the bottom of the filter, and the clarified water after sedimentation and solid-liquid separation flows to the center through the gap between the stacked funnel separators 3, and overflows from the circular opening at the top to the rectangular water tray 35, and then flows from the water tray 35 to the transfer tray 37. The first water outlet 39 at the bottom of the transfer tray 37 is connected to the main pipe of the sprinkler module 8 in the multi-layer medium filtration area 13 through a pipe. The clarified liquid that has undergone primary chemical treatment will flow into the sprinkler module 8 from the first water outlet 39 of the transfer tray 37 by its own gravity.

[0073] The sprinkler pipes on the sprinkler module 8 are equipped with micropores, through which the clarified liquid is evenly sprayed onto the surface of the multi-layer media filter assembly 11. The clarified liquid then flows slowly downward under its own gravity, passing through the multi-layer media filter assembly 11 in sequence, achieving progressive filtration from the larger filter media particle size at the top layer to the smaller filter media particle size at the bottom layer of the media filter area. Common filter media in the multi-layer media filter area 13 include, but are not limited to, anthracite, activated carbon, coconut shells, and sand and gravel of varying particle sizes. The multi-layer media filter assembly 11 can have different media arrangements, varying media layer depths, and varying media void sizes, allowing for appropriate selection and coordination based on the different water purification requirements of different regions. For example, in rural areas where fertilizer use is common and surface water contains relatively high levels of nitrogen and ammonia, zeolite can be used as the media material. Activated carbon can be used for adsorption treatment of surface water with high levels of heavy metals or odor. Gravel is also a common filter element material, often used when total suspended solids are less than 500 mg / L. The selection and combination of filter media materials are not restricted. The selection of specific filter media needs to be determined based on the local water quality level and local water use requirements, and should be adapted to local conditions.

[0074] Residual suspended matter and colloidal particles in the clarified liquid are blocked by the multi-layered media filter assembly 11, further removing impurities from the clarified liquid. The clarified liquid passes through the multi-layered media filter assembly 11 and reaches the bottom of the multi-layered media filter zone 13, where porous wedge-shaped filter screens are evenly laid. The filtrate flows through the pores into the wedge-shaped filter screens. The collected filtrate is then connected to the main pipe of the wedge-shaped wire filter tube 12 and discharged through the filtrate discharge port 38.

[0075] When the water purification system is operating normally, the electric three-way valve 9 connects the filtrate discharge port 38 and the second outlet pipe 24; the second delivery pump 32 starts and begins to operate, pumping the filtrate out of the wedge-shaped steel wire filter tube 12 and delivering it to the ultraviolet disinfection module 25 for sterilization and disinfection, directly killing various bacteria, viruses, and other pathogens in the purified water. The treated purified water will be pumped from the outlet of the ultraviolet disinfection module 25 through the delivery pipe into the sealed purified water storage tank 20 for storage. The sealed purified water storage tank 20 is equipped with a water level sensor. When the water level sensor senses a high water level, it will stop the second delivery pump 32 and the first delivery pump 33, suspending the pumping of filtrate from the multi-layer media filter area 13, preventing water from overflowing from the water treatment reaction unit 4 and the multi-layer media filter area 13, and also preventing water from overflowing out of the tank due to excessive water level, resulting in waste. The balancing area 15 is also equipped with a corresponding water level sensor. The working principle of this water level sensor is consistent with that of the above-mentioned water level sensor and will not be repeated here. Taking into account the storage time of purified water, the distance from the purified water reservoir to the water intake point, and the variability of the internal conditions of the water distribution pipeline, secondary pollution is avoided. A certain dose of chloride can be added to the closed purified water storage cylinder 20 for disinfection. The specific type of disinfectant and the dosage level need to be designed according to the local surface water quality and the purified water output requirements. The chloride disinfectant can be stored in a dosing buoy. The buoy is provided with a rotatable dosing opening, which can be rotated to change the size of the opening, thereby adjusting the overall dosage speed of the agent. The dosage level needs to be specifically measured according to the local surface water quality, the storage time of purified water in the reservoir, and the specific state and length of the pipeline from the reservoir to the water intake point, and adapted to local conditions; the user can connect the pipeline to the water intake 23 of the closed purified water storage bar to lead the purified water to the place where it is needed.

[0076] The sludge accumulated at the bottom of the water treatment reaction section 4 needs to be cleaned and discharged regularly to prevent clogging. The sludge can be discharged through the bottom sludge discharge port. The sludge discharge valve 30 connects the sludge discharge port and the sludge discharge pipe 29, and the other end of the sludge discharge pipe 29 is connected to the sludge dewatering bag 17. The sludge discharge is controlled by controlling the sludge discharge valve 30; when the sludge discharge valve 30 is opened, the water-containing sludge in the water treatment reaction section 4 is pressed into the sludge dewatering bag 17 through the sludge discharge valve 30 and the sludge discharge pipe 29 by its own gravity for sludge dewatering. The residual liquid in the sludge will pass through the sludge dewatering bag 17 and flow back to the balancing area 15 for further processing. The dehydrated sludge solids can be collected for centralized disposal, reducing transportation costs and the carbon emissions of discarded sludge. Reprocessing the residual liquid in the sludge can reduce the waste of water resources while maximizing the extraction of usable clean water.

[0077] In order to ensure the filtration efficiency and service life of the multi-layer media filter assembly 11, the multi-layer media filter area 13 is equipped with a backwash subsystem. The filter device needs to be backwashed periodically to remove impurities and pollutants remaining between the multi-layer media components to maintain the filtration efficiency. When the multi-layer media filter area 13 needs to be backwashed, the electric three-way valve 9 will close the channel that originally connected the filtrate discharge port 38 and the second outlet pipe 24, and instead connect the channel between the filtrate discharge port 38 and the backwash liquid discharge pipe 5. The clean water in the closed clean water storage cylinder 20 will be used for backwashing. After the channel between the filtrate discharge port 38 and the backwash liquid discharge pipe 5 is connected, due to the height difference between the equipment, the backwash liquid in the closed clean water storage cylinder 20 can generate a certain impact force through its own gravity and height difference, and the entire backwash process can be completed without the intervention of external force and additional electrical equipment; the backwash liquid flows out from the backwash liquid discharge port 1, is transported to the filtrate discharge port 38 through the backwash pipe and the electric three-way valve 9, and is finally sent to the backwash liquid evenly laid on the multi-layer media filter. The main channel and branch diameters of the wedge-shaped steel wire filter tube 12 at the bottom of area 13; the backwash liquid flows out from the pores around the wedge-shaped steel wire filter tube 12 and enters the multi-layer media filter assembly 11 from the bottom. When the filter assembly is backwashed from bottom to top, the backwash liquid will flow upward from the bottom of the multi-layer media filter assembly 11. The backwash liquid is continuously added to flush the pollutants intercepted by the filter medium to the top layer of the multi-layer media filter assembly 11. The backwash wastewater overflows through the triangular weir on the triangular weir partition 14 and flows to the balance tank for wastewater reprocessing.

[0078] Compared to existing technologies, this system maximizes the use of water's own gravity for water transport and backwashing within the pipeline, reducing additional power consumption. Furthermore, during the dosing process, by altering the water flow and incorporating static mixing blades within the pipeline, the raw water and the chemical are thoroughly mixed, minimizing the water purification system's power requirements. A first water brushless motor centrifugal pump connects the balancing zone 15 to the vortex water purifier. A second brushless motor centrifugal pump facilitates the flow of clean water within the pipeline connecting the multi-layer media filtration zone 13, the UV disinfection module 25, and the enclosed clean water storage tank. Compared with other electric centrifugal pumps on the market, brushless motor centrifugal pumps are more energy-efficient, thereby reducing the power burden in remote areas. Considering that the centrifugal pump, the equipment control area 41 and the ultraviolet disinfection module 25 require a small amount of additional electricity to drive the normal operation of the system, the surface water purification system can consider installing solar photovoltaic panels on the closed water purification tank at the top of the standardized, low-carbon, modular water treatment system based on actual conditions such as local power supply, location and weather, to ensure that the surface water purification system can still operate independently when disconnected from the power grid.

[0079] Compared to existing technologies, the present invention utilizes multi-stage surface water treatment, significantly reducing the amount of impurities, heavy metals, and ammonia nitrogen in the water. This design divides the water treatment system into three compact modular units, significantly reducing the space required for water purification equipment and facilitating transportation. The entire water purification process is largely automated, with a control box controlling most system operations. This makes it easy to use and install, reducing the need for manual system management. Furthermore, chemicals and media can be selected based on local conditions and resources, reducing the need to import materials and consumables from other locations and the carbon emissions associated with transportation.
