Description

Technical Field

[0001] This invention belongs to the field of water purification equipment technology, and in particular relates to a large-scale deployable modular water purification equipment, which is specifically applicable to seawater desalination, brackish water desalination, sewage reuse and reclaimed water drinking treatment scenarios, and can meet the rapid water supply needs of areas far from infrastructure and harsh environments. Background Technology

[0002] As the global water shortage intensifies, the demand for seawater desalination, wastewater treatment plant effluent reuse, and reclaimed drinking water purification continues to grow. Simultaneously, in special scenarios such as emergency water supply, field operation water supply, and freshwater supply to islands, as well as in remote mining areas, islands, and emerging towns far from infrastructure, the need for "rapid deployment, flexible adaptation, and efficient expansion" of water treatment facilities is becoming increasingly prominent. Regardless of whether physical, chemical, or biological water treatment processes are used, the structural form of the equipment directly determines its ease of transportation, on-site installation efficiency, and long-term operational stability. Traditional fixed-structure equipment is difficult to adapt to rapid response needs, while simple modular equipment has shortcomings in functional expansion and environmental tolerance, becoming a core bottleneck restricting the implementation of water treatment technologies in special scenarios.

[0003] Currently, water treatment equipment is mainly divided into two categories: traditional fixed type and simple modular type. Traditional fixed equipment, such as ground-mounted sewage treatment plants and fixed pure water stations, regardless of the water treatment process they employ, all rely on concrete civil engineering foundations and integrated rigid structures. On the one hand, this type of equipment requires on-site casting and is greatly affected by the environment. For example, in the Middle East, where temperatures are high, droughts are severe, and sandstorms are frequent, workers have poor tolerance, equipment is easily eroded by sandstorms, and outdoor civil engineering construction is not only inefficient, but in areas lacking mature industrial infrastructure and skilled workers, the construction cycle is generally as long as 12-36 months, making it impossible to quickly respond to sudden water supply needs or new regional construction demands. On the other hand, once a fixed concrete structure is built, it is impossible to adjust its scale according to changes in production capacity, and it is also difficult to relocate to other demand points, resulting in extremely poor flexibility. While containerized water treatment equipment offers improved transportability by being compatible with conventional freight transport, regardless of whether it incorporates physical filtration modules, chemical sedimentation, or biological treatment units, it employs an integrated welded or fixed installation design. Core components (such as filter module tanks, reaction tanks, and pump / valve assemblies) are rigidly connected to the container, requiring disassembly of surrounding structures for maintenance, and even complete modification for upgrading or replacing process units. Furthermore, the processing capacity of a single container is limited, typically between 50-200 cubic meters. 3 / d When multiple tanks are connected in parallel to increase production capacity, the fluid pipelines between each tank, such as raw water, produced water, and chemicals, need to be spliced ​​with the electrical lines on site one by one. The connection process is complicated, the construction volume is large, and water pollution or equipment failure is easily caused by interface sealing problems. It does not fundamentally solve the core needs of "rapid deployment and flexible expansion".

[0004] The core problems of existing water treatment equipment lie in its structural design, specifically: First, low deployment efficiency and poor adaptability to harsh environments: Traditional fixed equipment has a construction cycle of 12-36 months, and on-site construction is greatly affected by high temperatures, sandstorms, and terrain. Precision components (such as pumps, valves, and sensors) are easily damaged by the environment; containerized equipment requires extensive on-site construction for multiple units in parallel, and the deployment cycle is still as long as 6-8 months, which cannot meet the needs of emergency or rapid construction. Second, weak structural flexibility and process adaptability: Traditional equipment has a fixed structure and cannot switch processes according to treatment needs (such as switching from wastewater reuse to brackish water desalination); the internal components of containerized equipment are fixed, and the failure of a single process unit requires the entire unit to be shut down for maintenance, and replacing different types of water treatment units is also difficult. The internal structure needs to be redesigned, resulting in high adaptation costs; third, insufficient functional scalability and space utilization: existing modular equipment lacks standardized connection interfaces, and fluid and electrical connections become chaotic when expanding multiple modules, making it impossible to achieve flexible expansion such as horizontal laying (increasing processing capacity) or vertical stacking (saving space); moreover, most equipment has narrow internal operating space, making later maintenance and component replacement inconvenient; fourth, lack of operating environment control: whether traditional or simple modular equipment, there is a lack of internal protection design for harsh environments - high temperature can easily lead to aging of pump and valve seals and failure of electrical components, strong winds and sand can easily contaminate the treatment unit (such as clogging the filter module medium and affecting sensor accuracy), and low temperature can easily lead to pipe freezing, which seriously shortens the service life and operational stability of the equipment.

[0005] Therefore, existing technologies suffer from problems such as low deployment efficiency, long construction cycles, poor flexibility, and difficulty in adapting to the needs of rapid construction under harsh weather conditions, which urgently need to be addressed. Summary of the Invention

[0021] The present invention further explains that the multi-membrane core processing submodule includes a multi-membrane membrane module and a booster pump for providing inlet water pressure to the multi-membrane membrane module.

[0022] The present invention further illustrates that the booster pump is placed in a sealed noise control zone and installed at the bottom of the noise control zone by means of a shock-absorbing pad. The noise control zone forms a composite noise reduction structure by lining the inner wall with sound-absorbing cotton and / or setting a sealed soundproof door.

[0023] The present invention further illustrates that the water production buffer submodule includes a water production tank for storing purified water.

[0024] The present invention further explains that the large-scale deployable modular water purification equipment also includes an automatic control submodule with a built-in PLC control cabinet, which is used to centrally control the power units, execution units and sensing units in the water purification equipment to realize the automated operation of the equipment.

[0025] The present invention further explains that the plurality of sub-modules also include auxiliary function sub-modules, the auxiliary function sub-modules including a chemical cleaning sub-module; the chemical cleaning sub-module is equipped with a cleaning solution storage unit and a circulation pump, used for periodic maintenance and cleaning of the membrane components in the water purification equipment.

[0034] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-5 The present invention provides a technical solution: a large-scale deployable steel structure low-carbon modular water purification equipment, including a prefabricated deployable steel structure module 1, which is composed of a stainless steel sandwich panel 2 and a prefabricated steel structure module. The multi-membrane control system module is detachably integrated into the prefabricated deployable steel structure module 1; The multi-membrane control system module consists of multiple functionally independent sub-modules that are fluidly connected through pipes and quick-release interfaces 12. Each sub-module has an independent mounting position and can be independently disassembled from the prefabricated deployable steel structure module 1. The prefabricated deployable steel structure module 1 has foldable or deployable support frames on its side walls and / or top walls. After the support frames are deployed, they are used to expand the operating space and / or load-bearing area of ​​the prefabricated deployable steel structure module 1. The prefabricated deployable steel structure module 1 is provided with quick-connect sealed pipe interfaces 4 on its side walls, top walls and / or bottom walls, which are used to realize fluid communication and expansion connection of multiple prefabricated deployable steel structure modules 1 in the horizontal and vertical directions.

[0036] The beneficial effects of the above technical solution are as follows: By deeply modularizing the water treatment system and integrating it into the prefabricated deployable steel structure module 1, the equipment achieves a "skid-mounted" design. Its core advantages are reflected in the following aspects: the assembly and performance testing of the entire set of equipment are completed in the workshop, ultimately forming a standardized, independently transportable functional module; during the on-site deployment phase, no traditional civil construction is required. Only a number of prefabricated deployable steel structure modules 1 that have been transported to the site need to be skid-mounted and spliced, and the support frames of the module's side walls and / or top walls need to be deployed simultaneously. The pre-set quick-connect sealed pipe interfaces 4 can then be connected to quickly integrate them into a large-scale integrated water treatment device; this deployment method simplifies on-site operations to mechanical connection operations, so that the total cycle from the arrival of the equipment on site to completion of commissioning and operation can be controlled within 30 days, greatly improving deployment efficiency. It is especially suitable for scenarios with weak infrastructure or harsh environments (such as high temperature and sandstorms, remote areas without infrastructure), and can quickly form a stable water treatment capacity.

[0037] Meanwhile, the prefabricated deployable steel structure module 1 is based on a combination design of "plate + prefabricated frame". It can be folded and retracted during transportation, and the volume after folding is only 40%-60% of the unfolded state. The module size can be designed according to the international standard container transportation size, without the need for special transportation equipment, effectively reducing transportation costs. Moreover, after folding, the overall center of gravity of the module is concentrated, and loading and unloading operations can be completed with only small forklifts or cranes. It can be adapted to special areas such as remote mining areas and islands that lack large lifting equipment, and completely solves the problems of "high transportation difficulty and high component damage rate" of traditional fixed water treatment equipment.

[0038] Secondly, the core components of the prefabricated deployable steel structure module 1, such as the frame, plates, and basic fluid / electrical interfaces 13, are all standardized prefabricated and pre-assembled in the factory. On-site, deployment and basic assembly can be achieved only through hinges 15 and telescopic connectors 16, which can be operated by 2-4 workers without professional tools. The independent hoisting of the superimposed water purification sub-module (relying on independent installation positions and quick-release interfaces 12) means that a single module can be transported and put into full use in just 20-30 days. Compared with the 12-36 month on-site civil engineering cycle of traditional fixed equipment and the 1-2 month on-site pipeline splicing cycle of multiple containerized equipment, the deployment efficiency of this equipment is improved by more than 90%. It can quickly respond to scenarios with rigid requirements for "timely commissioning" such as emergency water supply and new town construction, and solve the problems of "slow deployment and reliance on on-site construction" of existing equipment.

[0039] Third, the side walls and / or top walls of the prefabricated deployable steel structure module 1 are equipped with foldable or deployable support frames. After the support frames are deployed, spatial connections between multiple modules can be achieved. For example, the right side wall support frame of module A can be deployed as the load-bearing bottom surface of module C, and the top wall support frame of module B can be deployed as the top protective structure of module C, thus expanding the overall operating space and / or load-bearing area by 1.5 times. In conjunction with the pre-installed quick-connect sealed pipe interfaces 4 on the side walls of the prefabricated deployable steel structure module 1, multiple modules can be flexibly laid horizontally or stacked vertically: when three modules are connected horizontally in parallel, the processing capacity can be increased from 100m² for two single modules. 3 / d×2 increased to 100m 3 / d×3; When two modules are stacked vertically, the floor space is reduced by 50% compared to single-module deployment, and the fluid and electrical connections between multiple modules can be completed within 2 hours; Compared to existing containerized water treatment equipment that requires on-site welding of pipes and debugging of lines when multiple containers are connected in parallel, this equipment completely solves the pain points of existing modular equipment such as "long expansion cycle and easy connection failure" through the collaborative design of support frame and standardized quick-connect interface, and can flexibly adapt to different production capacity scales and site restriction scenarios.

[0040] Fourth, enhanced tolerance to harsh environments ensures stable equipment operation: The prefabricated deployable steel structure module 1 uses steel components as the main supporting frame, with a wind and sand impact resistance strength of up to 1.2MPa, which can resist damage to the structure from strong winds and sand. At the same time, the materials can be flexibly selected according to the application scenario. For example, rock wool sandwich panels with a high temperature resistance of up to 600℃ are used in high-temperature areas, and stainless steel core panels with salt and alkali corrosion resistance are used in high-salt areas. Combined with the fully enclosed design of the module, it can form a stable protective environment inside the space, withstanding a temperature range of -20℃ to 60℃. Compared with traditional fixed equipment for open-air construction (high temperature easily leads to aging of pump and valve seals, and wind and sand easily contaminate sensor equipment, with an equipment failure rate of over 30%) and containerized equipment with non-enclosed structure (wind and sand easily penetrate the interior, affecting the operation of the water treatment unit), this equipment can isolate external harsh environmental interference, reduce the equipment failure rate by more than 80%, and ensure stable operation in scenarios such as high temperature and wind and sand in the Middle East, high salt in islands, and low temperature in remote mining areas.

[0041] Fifth, improved process adaptability and maintenance flexibility: The water purification equipment's "independent functional sub-modules + independent installation positions" design allows for the separate disassembly and assembly of sub-modules such as raw water pretreatment, core treatment, and product water buffer. Replacing the core treatment sub-module with a different process, for example, switching from a biological treatment module to a membrane separation module, takes only 20 minutes without structural module modification. In case of a single sub-module failure, it can be disassembled and maintained independently without requiring a complete shutdown. Compared to traditional equipment where "process switching requires structural modifications and fault maintenance requires a complete shutdown," this equipment reduces process adaptability costs by 80% and increases equipment utilization by 80%. Simultaneously, sub-modules are fixed using standardized mechanical connectors, and spare parts can be directly purchased from the market, reducing maintenance costs by 80%.

[0042] Based on further improvements to the above equipment, the prefabricated frame structure 11 of the prefabricated deployable steel structure module 1 adopts steel components as the main support structure, and the plate material is selected from any of the following materials: stainless steel core plate, flame-retardant polystyrene sandwich panel, glass fiber reinforced composite sandwich panel, rock wool sandwich panel, aluminum honeycomb sandwich panel, straw fiber composite sandwich panel; the wall panels include the side wall, top wall and / or bottom wall of the equipment.

[0043] The beneficial effects of the above-mentioned further improvement scheme are as follows: using steel components as the main support structure can significantly improve the load-bearing strength and structural stability of the prefabricated frame, enhance its resistance to deformation, and enable it to withstand the weight of the water purification submodule and external environmental impacts such as wind pressure and vibration for a long time, thus preventing frame deformation during module deployment or transportation; the optional design of various board materials can realize "scenario-adaptive" material selection—for example, flame-retardant polystyrene sandwich panels can be used in high-risk fire protection scenarios, rock wool sandwich panels with a temperature resistance of 600℃ can be used in high-temperature environments, stainless steel core panels can be used in high-salt corrosion scenarios, aluminum honeycomb sandwich panels can be used in lightweight scenarios, and straw fiber composite sandwich panels can be used in environmental protection and low-cost scenarios, greatly expanding the application range of the equipment; at the same time, the wall panels cover the side walls, top walls and / or bottom walls to form a fully enclosed protective structure, which can isolate external dust, water vapor, sand and other impurities from entering the module, protect the precision components of the water purification submodule from contamination, and extend the service life of core components.

[0044] Based on further improvements to the above equipment, quick-connect sealed pipe interfaces 4 are provided on the side walls, top walls and / or bottom walls of the prefabricated deployable steel structure module 1.

[0045] The beneficial effects of the above-mentioned further improvement scheme are as follows: The quick-connect design can completely simplify the on-site pipeline connection process, eliminating the need for traditional welding, flange bolt tightening and other complex operations. Operators only need to manually plug and unplug to complete the interface connection. The connection time of a single interface can be shortened to 5-10 minutes, which greatly reduces the on-site construction time. At the same time, the sealing structure can effectively prevent fluids (such as raw water, purified water, and chemicals) from leaking during the transmission process, avoiding water waste or environmental risks caused by chemical leakage. It is especially suitable for the closed transmission requirements of various fluids in water treatment processes, ensuring the safety and environmental protection of equipment operation.

[0046] Based on the above improvements, the quick-connect sealing pipe interface 4 also includes an electrical interface 13 and a fluid interface 14. The electrical interface 13 and the fluid interface 14 can be integrated or not integrated. The fluid interface 14 is used to realize the fluid communication between multiple prefabricated deployable steel structure modules 1 in the horizontal and vertical directions. The electrical interface 13 is used to realize the power transmission and control signal transmission between multiple prefabricated deployable steel structure modules 1 to support the collaborative operation after modular expansion.

[0047] The beneficial effects of the above-mentioned further improvements are as follows: On the one hand, the fluid interface 14 supports horizontal (e.g., parallel deployment) and vertical (e.g., stacked deployment) connectivity of multiple modules, enabling flexible construction of various operating modes such as "single module independent operation - multi-module parallel expansion - multi-module stacking to reduce footprint"; on the other hand, the electrical interface 13 enables power sharing and signal synchronization among multiple modules, avoiding the need for each module to be configured with an independent power supply system and control unit, reducing the overall cost of the equipment, and the real-time transmission of control signals ensures the coordinated operation of multiple modules, avoiding the decrease in processing efficiency or equipment failure caused by inconsistent operating parameters between modules; and the "integrated setting," that is, merging the electrical and fluid interfaces 14 into a composite interface, can reduce the number of interfaces and simplify the design of the module's outer wall, while the "non-integrated setting" can flexibly adjust the interface position according to the module layout. The two setting methods adapt to different field installation scenarios and improve design flexibility.

[0048] Based on further improvements to the above equipment, the prefabricated deployable steel structure module 1 achieves the transformation between unfolded and folded states through hinges 15 and telescopic connectors 16; after the support frame is unfolded, it is fixed by fixing connectors 17 to ensure the structural stability of the expanded operating space and load-bearing area.

[0049] The beneficial effects of the above-mentioned further improvement scheme are as follows: The combined design of hinge 15 and telescopic connector 16 can realize the smooth switching between module folding and unfolding. During the transportation stage, the side wall / top wall is folded by hinge 15 and the frame is retracted by telescopic connector 16, so that the module volume is compressed to 40%-60% of the unfolded state, which is compatible with the standard container transportation size and does not require special transportation equipment. When unfolding on site, only the side wall / top wall needs to be pushed to rotate into place by hinge 15, and telescopic connector 16 extends to support the frame at the same time. The operation is simple and does not require professional tools. The fixed connector 17 (such as buckle and bolt locking parts) that supports the unfolded frame can firmly fix the frame to the main module, avoid the frame from shaking or displacement when under load or external force, ensure that the expanded operating space is safe and usable, and meet the on-site operation needs such as equipment maintenance and consumable replacement.

[0050] Based on further improvements to the above equipment, the water purification equipment can be any one of seawater desalination equipment, sewage treatment equipment, or reclaimed water drinking water treatment equipment.

[0051] The beneficial effects of the above-mentioned further improvement scheme are: it achieves a high degree of flexible adaptation of water purification functions—the same set of prefabricated deployable steel structure modules 1 does not require frame modification, installation position adjustment or interface reconstruction. It can quickly replace and assemble seawater desalination equipment, sewage treatment equipment and reclaimed water drinking water treatment equipment simply by leveraging the detachable integration characteristics of the water purification equipment. For example, when the equipment needs to be transferred from an island seawater desalination scenario to an urban sewage treatment scenario, it is only necessary to remove the original integrated seawater desalination equipment and detachably integrate the sewage treatment equipment into the module through the standardized connection structure preset by the structural module. If it is necessary to adapt to emergency reclaimed water drinking water treatment needs in the future, the above detachable replacement process can be repeated without modifying the structural module itself. The function switching time of a single set of equipment can be greatly shortened, significantly improving the equipment's flexible response capability to different water treatment scenarios.

[0052] Based on further improvements to the above equipment, the detachable connection can be achieved through a pipe and quick-release interface 12 to achieve fluid communication, or through flange 19 to achieve fluid communication.

[0053] The beneficial effects of the above-mentioned further improvement scheme are: the quick-release interface 12 is adapted to sub-modules that require frequent disassembly and assembly (such as the product water buffer sub-module), and the replacement time is controlled within 20 minutes; the flange 19 connection is adapted to high-pressure fluid transmission sub-modules (such as the multi-membrane core processing sub-module 6), with excellent pressure resistance and sealing performance, avoiding leakage; both methods do not require hot work, improving maintenance safety and solving the problems of "cumbersome disassembly and assembly and easy leakage of high-pressure transmission" in traditional equipment.

[0054] Based on further improvements to the above equipment, the water purification equipment and the prefabricated deployable steel structure module 1 are fixed together by standardized mechanical connectors 18, and fluid and electrical connections are achieved through quick-release interfaces 12.

[0055] The beneficial effects of the above-mentioned further improvement scheme are: the standardized mechanical connector 18 ensures a firm connection, avoids equipment displacement during transportation or operation, and spare parts can be purchased universally; the quick-release interface 12 enables the overall disassembly and assembly of the water purification equipment, and the overall replacement time is controlled within 2 hours, improving the efficiency of equipment maintenance and upgrade, and solving the problem of "complex module connection and difficult overall replacement" of traditional equipment.

[0056] Based on further improvements to the above equipment, the prefabricated deployable steel structure module 1 is a cuboid or cube structure, with its sides and / or bottom surface being stainless steel sandwich panels 2, and its top being enclosed with stainless steel sandwich panels 2 or other materials.

[0057] The beneficial effects of the above-mentioned further improvement scheme are: the regular cuboid / cube structure facilitates the stacking or parallel deployment of multiple modules, resulting in high space utilization; the stainless steel sandwich panel 2 improves the corrosion resistance and strength of the sides and bottom, and the top material can be flexibly selected to meet the needs of weight reduction or heat preservation, solving the problems of "poor space adaptability and easy local corrosion" of traditional equipment.

[0058] Based on further improvements to the above equipment, the submodule includes at least a raw water treatment submodule, a multi-membrane core treatment submodule 6, and a product water buffer submodule.

[0059] The beneficial effects of the above-mentioned further improvement scheme are: forming a complete process of "raw water pretreatment - core purification - product water storage", the raw water treatment submodule removes suspended solids to avoid membrane clogging, the multi-membrane core treatment submodule 6 ensures that the effluent meets the standards, and the product water buffer submodule balances supply and demand fluctuations. It does not require reliance on external auxiliary equipment and solves the problem of "incomplete process and reliance on external equipment" of traditional equipment.

[0060] Based on further improvements to the above equipment, the multi-membrane core processing submodule 6 includes a biofilm processing module and / or a physical auxiliary processing module.

[0061] The beneficial effects of the above-mentioned further improvement scheme are: the biofilm treatment module (such as biological contact oxidation) degrades organic matter and is suitable for organic polluted raw water; the physical auxiliary treatment module (such as air flotation module 39 and filtration module 40) removes tiny impurities and ensures the stability of the membrane module; the "and / or" design can be flexibly combined according to water quality, improve water quality adaptability, and solve the problem of "single water quality adaptability" of traditional equipment.

[0062] Based on further improvements to the above equipment, the biofilm treatment module is at least one of a moving bed biofilm reactor, a biological contact oxidation module, and a submerged biofilm module.

[0063] The beneficial effects of the above-mentioned further improvement scheme are: the moving bed biofilm reactor has high organic matter degradation efficiency and is suitable for high-concentration organic wastewater; the biological contact oxidation module has a simple structure and is easy to maintain, and is suitable for small and medium-sized scales; the submerged biofilm module occupies little space and is suitable for compact spaces; multiple types are available to adapt to different treatment scales and spaces, solving the problem of "poor adaptability of biological treatment" of traditional equipment.

[0064] Based on further improvements to the above equipment, the physical auxiliary processing module includes at least one of the following: air flotation module 39, filtration module 40, and chemical dosing module 41, which is used to pre-treat impurities in the core membrane treatment stage of the multi-membrane method or to assist in ensuring the stable operation of the membrane module.

[0065] The beneficial effects of the above-mentioned further improvements are as follows: the flotation module 39 can efficiently remove tiny suspended solids, oil droplets, and colloidal particles from the raw water, preventing such impurities from adhering to the surface of the ultrafiltration membrane and forming a filter cake layer, thus ensuring the water permeability of the ultrafiltration membrane; the filtration module 40 further intercepts the tiny impurities not removed by the flotation module 39, providing "near-impurity-free" feed water for the subsequent ultrafiltration membrane and reducing physical clogging of the ultrafiltration membrane; the chemical treatment module 41 specifically addresses the core fouling problems of ultrafiltration and reverse osmosis membranes: flocculants enhance the aggregation of tiny particles, improving the efficiency of the filtration module 40; for reverse osmosis membranes, scale inhibitors prevent calcium and magnesium ion scaling on the membrane surface, preventing a decrease in desalination rate due to membrane pore blockage; continuous addition of reducing agents eliminates the oxidative damage to the reverse osmosis membrane caused by residual chlorine in the raw water; intermittent addition of non-oxidizing bactericides prevents the growth of microorganisms and the formation of a biofilm within the reverse osmosis membrane module; reverse osmosis Intermittent cleaning with compatible acid and alkali agents can restore desalination rate and permeate flow when membrane performance declines. For ultrafiltration membranes, sodium hypochlorite is continuously added to prevent microbial growth within the ultrafiltration membrane module. Intermittent alkali addition cleans organic matter on the ultrafiltration membrane surface to restore membrane flux. Intermittent acid addition cleans inorganic salts on the ultrafiltration membrane surface to restore membrane flux. Intermittent cleaning with compatible acid and alkali agents further restores the ultrafiltration membrane flux and permeate flow. The flotation module 39, filtration module 40, and chemical dosing form a synergistic effect of "progressive pretreatment + targeted protection," which not only provides high-quality feed water conditions for the core membrane modules (ultrafiltration and reverse osmosis) of multi-membrane processes, but also reduces physical, chemical, and biological membrane fouling at the source. At the same time, it reduces the frequency of membrane cleaning, reduces the wear and tear on the membrane, and completely solves the problems of "easy clogging of membrane modules, short lifespan, and unstable core treatment efficiency" in traditional equipment.

[0066] Based on further improvements to the above equipment, the raw water treatment submodule includes at least one of a quartz sand filter 42 and a security filter 43.

[0067] The beneficial effects of the above-mentioned further improvement scheme are: the quartz sand filter 42 removes impurities with a particle size >10μm, avoiding scratching subsequent filter elements; the security filter 43 intercepts tiny colloids, serving as the "last protection" for the membrane module; and the staged filtration ensures thorough pretreatment of raw water, solving the problems of "insufficient pretreatment and easy damage to membrane modules" in traditional equipment.

[0068] Based on further improvements to the above equipment, the multi-membrane core processing submodule 6 includes a multi-membrane module and a booster pump 21 for providing inlet water pressure to the multi-membrane module.

[0069] The beneficial effects of the above-mentioned further improvement scheme are: multi-membrane modules (such as reverse osmosis and ultrafiltration) remove salt, organic matter and other substances as needed to ensure that the effluent meets the standards; booster pump 21 provides stable inlet water pressure, ensures membrane flux, and solves the problems of "low membrane treatment efficiency and high energy consumption" of traditional equipment.

[0070] Based on further improvements to the above equipment, the booster pump 21 is placed in the sealed noise control zone 22 and installed at the bottom of the noise control zone 22 by means of the shock-absorbing pad 23. The noise control zone 22 forms a composite noise reduction structure by laying sound insulation cotton 24 on the inner wall and / or setting a sealed sound insulation door 25.

[0071] The beneficial effects of the above-mentioned further improvement scheme are: the composite noise reduction structure reduces external noise to below 50dB; the shock absorption pad 23 absorbs more than 80% of the vibration, avoids loosening of the module frame and leakage of the interface, solves the problem of "high operating noise and vibration damage to equipment" of traditional equipment, and can also provide a quiet working environment for staff.

[0072] Based on further improvements to the aforementioned equipment, the water production buffer submodule includes a water production tank 26 for storing purified water.

[0073] The beneficial effects of the above-mentioned further improvement scheme are: the water production tank 26 buffers the fluctuations in water intake and usage, avoiding water supply interruptions; the liquid level sensor links with the equipment to adjust the processing load, reducing energy waste, improving water supply reliability, and solving the problems of "unstable water supply and energy waste" in traditional equipment.

[0075] The beneficial effects of the above-mentioned further improvement scheme are: 1. Precise parameter control to adapt to dynamic changes in water quality: The PLC control cabinet 27 can automatically adjust the core parameters in milliseconds based on the real-time feedback data from the sensor unit (such as raw water flow, turbidity, hardness, and product water TDS value). For example, when the raw water flow suddenly increases, the frequency of the booster pump 21 is automatically increased to maintain the stability of the inlet water pressure of the membrane module (ensuring that the reverse osmosis membrane pressure fluctuation is ≤ ±0.05MPa); when the product water TDS value exceeds the standard, the opening of the inlet valve is automatically fine-tuned to control the inlet water rate, avoiding overload operation of the membrane module and solving the problems of lag and low accuracy in traditional manual parameter adjustment; 2. Achieve precise dosing, reduce costs and ensure treatment effect: Relying on the real-time data of the raw water hardness sensor and turbidity sensor, the PLC can dynamically calculate and control the dosing. The opening degree and dosing time of the dosing valve save 20%-30% of the chemical cost compared with traditional manual dosing, solving the pain point of "manual dosing based on experience and inaccurate dosage" in traditional equipment; 3. Remote monitoring and fault linkage, suitable for unattended scenarios: The PLC control cabinet supports remote communication, and the staff can view the equipment operating parameters (such as membrane inlet water pressure, dosing amount, and product water flow) in real time through the terminal, and remotely modify the core parameters (such as setting the reverse osmosis membrane inlet water pressure threshold and flocculant dosing benchmark value); when the sensing unit detects an abnormality (such as excessive membrane pressure or dosing pump failure), the system will automatically trigger an alarm and link the execution unit (such as closing the inlet valve and stopping the dosing) to avoid equipment damage, which is fully adapted to unattended scenarios and reduces the manual inspection cost by more than 80% compared with traditional equipment.

[0076] Based on further improvements to the above equipment, several sub-modules also include auxiliary function sub-modules, including a chemical cleaning sub-module; the chemical cleaning sub-module is equipped with a cleaning solution storage unit and a circulation pump, used for regular maintenance and cleaning of the membrane components in the water purification equipment.

[0077] The beneficial effects of the above-mentioned further improvement scheme are: different cleaning solutions can specifically remove membrane fouling (acidic solutions for descaling and alkaline solutions for removing organic matter), and the membrane flux can be restored to more than 90% of its initial value after cleaning; regular cleaning can extend membrane life, reduce consumable costs, and solve the problem of "severe membrane fouling and frequent replacement" in traditional equipment.

[0078] Based on further improvements to the above-mentioned equipment, the prefabricated deployable steel structure module 1 also integrates an independent fresh air system. The fresh air system includes at least one of an air filtration unit and a temperature and humidity control unit, which is used to provide filtered and / or temperature-controlled fresh air to the interior of the prefabricated deployable steel structure module 1.

[0079] The beneficial effects of the above-mentioned further improvement scheme are: the air filtration unit prevents dust from contaminating electrical components and membrane modules; the temperature and humidity control unit controls the internal environment at 15-35℃ and 40%-60%, ensuring the optimal operating condition of the equipment, solving the problem of "weak adaptability to harsh environments and easy damage to internal equipment" of traditional equipment, and also providing a comfortable working environment for staff.

[0080] Based on further improvements to the above equipment, the multi-membrane core treatment submodule 6 can be replaced with a physical, chemical, or biological water purification system according to the characteristics of the water source and the water output requirements. All types of systems are integrated through connectors and quick-release interfaces 12.

[0081] The beneficial effects of the above-mentioned further improvement scheme are: the treatment process can be switched without modifying the structural modules, such as changing high-turbidity raw water to a physical system and high-organic wastewater to a chemical system; the process switching time of a single module is less than 4 hours, the modification cost is reduced by more than 80%, and the problem of "fixed process and high modification cost" of traditional equipment is solved.

[0082] On the other hand, embodiments of the present invention also protect the application of a large-scale deployable modular water purification equipment as described above in seawater desalination, wastewater treatment plant effluent reuse, reclaimed drinking water purification systems, emergency water supply, field operation water supply, and island freshwater supply systems.

[0083] The beneficial effects of adopting the above application scheme are: to accurately match the technological advantages of equipment with the needs of multiple scenarios, such as seawater desalination for islands and rapid deployment for emergency scenarios, to maximize the advantages of equipment in "easy transportation, fast deployment and strong adaptability", and to solve the pain points of water treatment needs in different scenarios.

[0084] The multi-membrane core treatment submodule includes a physical water purification unit, a chemical water purification module, and a biological water purification module, and is equipped with an intelligent linkage switching system; The physical water purification unit adopts an integrated structure of folded ultrafiltration membrane and cyclone sedimentation. The chemical water purification unit is designed for precise dosing of reagents and integration with the reaction vessel, with a built-in monitoring probe that switches reagent compartments according to the type of water pollution. The biological water purification module adopts a structure with a biofilm carrier and anaerobic or aerobic switching, and switches between biofilm and activated sludge methods by adjusting the aeration intensity and water flow direction.

[0085] The working steps of the intelligent linkage switching system include: Step S1: Set up a multi-parameter sensor matrix at the water inlet to detect turbidity, pH value, chemical oxygen demand, heavy metal concentration, salinity, DO (dissolved oxygen), five-day biochemical oxygen demand and temperature. After the detection is completed, turn off the multi-parameter sensor matrix and transmit the data to the AI ​​control platform. The water source characteristics are determined within 10 seconds. Step S2: Based on the judgment result, the control platform uses a hydraulic drive device to realize the automatic insertion and removal of units and process combination. Step S3: Install an online water quality monitor at the outlet. If the water quality indicators do not meet the standards, the system will automatically return to step S2, forming a closed-loop feedback mechanism for the water quality.

[0086] In step S1, the AI ​​control platform has a built-in database that stores historical detection data. The system compares the historical detection data with the new detection data. If the ratio deviates significantly, the multi-parameter sensing matrix is ​​restarted to re-detect, collect data, and correct the data. This process continues until the ratio is within the normal range. Breaking away from the fixed process of traditional sewage treatment equipment, the water purification unit is transformed into a freely combinable unit, achieving the goal of adapting one device to thousands of water sources. Through the combination of AI sensing and control, the stability of the water purification effect is guaranteed, and the pain points of traditional equipment such as "difficult switching and poor adaptability" are solved. At the same time, the energy consumption for judging the characteristics of water sources is greatly reduced, and the judgment results are more accurate, thereby greatly improving the quality of water purification. By achieving closed-loop feedback of detection data and effluent, the water purification effect is further improved, and the cost is significantly reduced, saving on the amount of chemicals used while ensuring the quality of purified water.
