[0025] Seawater desalination technology is an important means of solving the shortage of freshwater resources. Its core process usually includes three stages: pretreatment, reverse osmosis desalination and post-treatment. The freshwater after seawater desalination can be used for water resource allocation in coastal water-scarce areas.

[0026] However, among related technologies, seawater desalination technology lacks dynamic and coordinated evaluation of relevant indicator parameters and data, and cannot assess the overall stability of the system based on the differences in the needs of water users.

[0027] Based on this, the present invention provides a seawater desalination water resource allocation and processing method, apparatus, equipment, and storage medium. This method involves acquiring a seawater source, pre-treating the seawater source using a pre-treatment system to form a first treated water source, performing reverse osmosis treatment on the first treated water source using a reverse osmosis membrane module to form a second treated water source, and then post-treating the second treated water source using a post-treatment system to form a third treated water source. The third treated water source is then delivered to the corresponding water-using terminals. Based on multiple relevant index parameters of the third treated water source, a stability evaluation coefficient is determined for each water-using terminal, and the overall stability of the system is determined based on the stability evaluation coefficients of each water-using terminal. This approach achieves dynamic collaborative evaluation of relevant index parameter data and assesses the overall stability of the system based on the differences in the needs of the water-using terminals.

[0028] To facilitate understanding of this embodiment, a detailed description of a seawater desalination water resource allocation and treatment method disclosed in this embodiment of the invention will be provided first.

[0029] Example 1

[0030] This invention provides a method for allocating and treating seawater desalination water resources, applied to a seawater desalination water resource allocation and treatment system. The system includes: a reverse osmosis seawater desalination device and various water-using terminals connected to the reverse osmosis seawater desalination device via pipelines; the reverse osmosis seawater desalination device includes a pretreatment system, a reverse osmosis membrane module, and a post-treatment system connected in sequence.

[0031] Figure 1 This is a flowchart illustrating a seawater desalination water resource allocation and processing method provided in an embodiment of the present invention. Figure 1 As shown, the seawater desalination water resource allocation and treatment method may include the following steps:

[0032] Step S101: Obtain seawater source, pre-treat the seawater source through a pre-treatment system to form the first treated water source.

[0033] The pretreatment system is a crucial step in seawater desalination or other seawater treatment processes. Seawater typically contains large particulate impurities (such as sand and shell fragments), suspended solids (tiny particles suspended in water, visible or invisible to the naked eye), and colloids (aggregates of small particles dispersed in water with a certain degree of stability). Reverse osmosis membranes are key components in seawater treatment, used for separation and purification. However, they are delicate and easily damaged. If large particulate impurities, suspended solids, and colloids directly enter the reverse osmosis membrane system, they may clog the membrane pores, reduce membrane flux and separation efficiency, or even damage the reverse osmosis membrane, shortening its lifespan. Therefore, the pretreatment system's role is to pre-treat the seawater through a series of physical or chemical methods such as filtration, sedimentation, and flocculation to remove large particulate impurities, suspended solids, and colloids, providing relatively clean feed water for subsequent reverse osmosis membrane treatment. This protects the reverse osmosis membrane and ensures the stable operation and treatment effect of the entire seawater desalination system.

[0034] Seawater sources are usually obtained directly from the ocean, such as from nearshore waters, deep-sea areas, and saltwater lakes or salt lakes.

[0035] Specifically, pre-treating the seawater source through a pre-treatment system to form a first treated water source may include: introducing the seawater source into the pre-treatment system; and sequentially subjecting the seawater source to physical filtration, biological filtration, chemical filtration, adsorption filtration, coagulation filtration, sedimentation filtration, and quartz sand filtration through the pre-treatment system to form the first treated water source.

[0036] The pretreatment system is located at the input end of the seawater source. After the seawater source is introduced into the pretreatment system, it undergoes physical filtration, biological filtration, chemical filtration, adsorption filtration, coagulation filtration, sedimentation filtration and quartz sand filtration in sequence through the physical filter, biological filter, chemical filter, adsorption filtration, coagulation filtration, sedimentation filtration and quartz sand filtration of the pretreatment system to form the first treated water source.

[0037] Among them, physical filters use mechanical methods to separate larger particles in seawater, biological filters decompose harmful elements in seawater through cultured bacteria, chemical filters use chemical agents to further remove impurities, adsorption filters adsorb proteins and trace elements in seawater, coagulation filters add water treatment agents to make colloidal particles and small suspended solids aggregate, sedimentation filters make flocs settle and separate, and quartz sand filters further remove fine suspended impurities.

[0038] Regarding the filtration methods of each filter:

[0039] Physical filters: These are installed at the beginning of the pretreatment system and use mechanical methods to separate larger particles from the incoming seawater, such as leftover feed particles, dead fish bones, and fish excrement. They are generally made of materials such as sponges, spray-bonded cotton, fine-mesh nylon nets, and palm leaf fibers.

[0040] Biological filters: These are used to further ecologically filter seawater that has been filtered by physical filters by decomposing harmful elements such as ammonium salts, nitrites, nitrates, and phosphates through cultured bacteria. They are generally made of materials such as bio-balls, ceramic rings, glass rings, and coral sand.

[0041] Chemical filters: These filters use chemical agents to further remove impurities from seawater filtered by biological filters. The agents used include water stabilizers, flocculants, algaecides, protein decomposers, and deodorizers.

[0042] Adsorption filters: Using materials with extremely high carbon content such as wood, coal, fruit shells, and animal bones, they adsorb proteins and trace elements from seawater filtered by chemical filters, decolorize, remove odors, and can also adsorb fish urine, microalgae in the water, and medicines.

[0043] Coagulation filter: After the seawater is filtered by the adsorption filter and pumped up, water treatment agents such as polyaluminum chloride, aluminum sulfate, and ferric chloride are added. The ions ionized by the agents react with the seawater to generate substances with adsorption properties. These substances destabilize and aggregate the colloidal particles and tiny suspended solids in the water that are not easy to settle, forming larger flocs that facilitate separation and sedimentation from the water.

[0044] Sedimentation filter: During the process of coagulation and the formation of flocs in the coagulation filter, the particles in the seawater settle to the bottom of the pool, and the sludge accumulates and thickens, and is periodically discharged from the filter pool.

[0045] Quartz sand filtration: A porous granular filter media layer, such as quartz sand, traps suspended particles in seawater after sedimentation and separation by a sedimentation filter screen through adhesion, further removing fine suspended impurities, organic matter, bacteria, viruses, etc., and making the water clear.

[0046] The reverse osmosis membrane assembly may include a reverse osmosis membrane, a support body, and a shell arranged sequentially from the inside out. The support body is used to support the reverse osmosis membrane, and the shell is used to protect the reverse osmosis membrane.

[0047] It should be noted that a reverse osmosis membrane is an artificial semi-permeable membrane with certain characteristics, made to mimic biological semi-permeable membranes. It is the core component of reverse osmosis technology in seawater desalination systems. Its pore size is extremely small, typically at the nanometer level. Its working principle is based on separating water from other substances by applying pressure higher than the osmotic pressure of the solution, ensuring that other substances cannot pass through the semi-permeable membrane. Furthermore, reverse osmosis membranes possess characteristics such as high desalination rate, high water flux, good chemical stability, and strong anti-fouling ability. Reverse osmosis membranes are generally made of materials such as cellulose acetate and aromatic polyamides.

[0048] Step S102: The first water source is treated by reverse osmosis through a reverse osmosis membrane module to form a second water source.

[0049] The reverse osmosis membrane assembly includes a reverse osmosis membrane, a support body for supporting the reverse osmosis membrane, and a shell for housing the reverse osmosis membrane and the support body. Water molecules in seawater pass through the reverse osmosis membrane, while corresponding salt impurities are retained by the reverse osmosis membrane.

[0050] Specifically, the process of treating a first water source with reverse osmosis through a reverse osmosis membrane module to form a second water source may include: pumping the first water source into the reverse osmosis membrane module using a high-pressure pump; and using the reverse osmosis membrane module to retain salt and impurities in the first water source and allow water molecules to pass through the reverse osmosis membrane to form the second water source.

[0051] In a natural process, water permeates from a low-concentration solution to a high-concentration solution. However, in the reverse osmosis process, by applying pressure higher than the osmotic pressure to the seawater, the water molecules in the seawater overcome the natural osmotic pressure and pass through the reverse osmosis membrane, while the salt, impurities, and other substances in the seawater are trapped on the other side of the membrane, thus achieving seawater desalination.

[0052] Step S103: The second treated water source is post-treated by the post-treatment system to form a third treated water source, and the third treated water source is delivered to the corresponding water-using terminal.

[0053] Specifically, the process of post-treating the second treated water source to form a third treated water source through a post-treatment system may include: introducing the second treated water source into the post-treatment system; and adjusting the hardness, pH value, disinfecting, deboron filtration, and nutrient content of the second treated water source through the post-treatment system to form a third treated water source.

[0054] The specific tasks for each stage are as follows:

[0055] Hardness adjustment: The hardness of the second-processed water source is adjusted by the hardness adjustment device in the post-treatment system to make the hardness of the water reach a suitable range, so as to avoid adverse effects on subsequent use due to excessively high or low hardness, such as preventing the impact on soil structure during irrigation or the impact on the living environment of organisms in wetland systems.

[0056] pH adjustment: Using a pH adjustment device to adjust the acidity or alkalinity of water, so that the pH value of the water is in a suitable range to meet the needs of organisms for survival and growth in wetlands, agricultural irrigation or ecological ditches. Different plants and organisms have different tolerance ranges for water acidity or alkalinity.

[0057] Disinfection: Water is disinfected using a disinfection device to kill harmful bacteria, viruses and other microorganisms in the water, preventing them from harming crops, wetland ecosystems or ditch ecosystems and ensuring water safety.

[0058] Boron removal filtration: Boron removal filtration is used to remove boron from water. Excessive boron content in water may be toxic to plant growth, so it needs to be controlled within a suitable concentration range.

[0059] Nutrient regulation: By using nutrient regulation devices, the nutrient content in the water is adjusted to provide suitable nutrients for the growth of organisms and crops in wetlands or ecosystems in ecological ditches, promoting their healthy growth and proper functioning.

[0060] The post-treatment system may include a hardness adjustment device, a pH adjustment device, a disinfection device, a deboron filtration device, and a nutrient adjustment device arranged in sequence.

[0061] The hardness adjustment device includes an ion exchange resin tank and a regeneration component. The ion exchange resin tank utilizes the properties of ion exchange resin to remove ions that cause hardness in desalinated water, such as calcium and magnesium ions, thereby reducing the hardness of the desalinated water. The regeneration component is used to restore the exchange capacity of the ion exchange resin. It includes a salt tank and a regeneration pump. The salt tank stores brine. When the ion exchange resin adsorbs a certain amount of calcium and magnesium ions, its exchange capacity decreases, requiring regeneration. The regeneration pump transports the brine from the salt tank to the ion exchange resin tank. The brine reacts with the calcium and magnesium ions adsorbed on the resin, restoring the resin's activity and its ability to remove hardness ions from the water. Regarding material selection, the ion exchange resin tank is preferably made of fiberglass lined with acid and alkali resistant rubber, and the salt tank is made of polyethylene.

[0062] The pH adjustment device includes a pH sensor, a metering pump, a dosing tank, and a mixing reaction tank. It is used to measure the pH value of the desalinated aqueous solution in real time, converting the acidity / alkalinity information of the desalinated solution into an electrical signal or other measurable signal so that subsequent systems can obtain the current pH value of the desalinated aqueous solution.

[0063] The dosing tank is a container for storing agents used to adjust the pH value. Depending on the direction of adjustment, the desalinated aqueous solution can be made acidic or alkaline. The dosing tank will contain the corresponding acidic or alkaline agents.

[0064] The metering pump is used to control the amount of medicine added in the dosing tank. It can accurately deliver the medicine in the dosing tank to the solution where the pH value needs to be adjusted according to the system's instructions, ensuring that the amount of medicine added matches the actual needs.

[0065] The mixing reaction tank is a container device for thoroughly mixing the reagent with the desalination solution to be adjusted. In this container device, the reagent is evenly dispersed in the desalination solution through stirring and other methods, thereby achieving effective adjustment of the pH value of the desalination solution.

[0066] The pH adjustment device monitors the solution pH in real time using a pH sensor. Then, a metering pump draws an appropriate amount of reagent from the dosing tank and adds it to the mixing reaction tank. The reagent and solution are mixed and reacted in the tank to ultimately adjust the solution pH.

[0067] The disinfection device includes an ultraviolet disinfection component, a sodium hypochlorite disinfection component, and an ozone disinfection component arranged in sequence.

[0068] The ultraviolet disinfection component consists of an ultraviolet lamp and a quartz sleeve. The ultraviolet lamp emits ultraviolet light of a specific wavelength to inactivate microorganisms in the desalinated water. The quartz sleeve protects the ultraviolet lamp and allows ultraviolet light to pass through, while preventing the ultraviolet lamp from directly contacting the water. By utilizing the bactericidal effect of ultraviolet light, the DNA and RNA structure of microorganisms are destroyed, causing them to lose their activity and reproductive ability, thereby achieving the purpose of disinfection.

[0069] The sodium hypochlorite disinfection assembly includes a sodium hypochlorite storage tank, a dosing pump, and a contact reaction tank. The sodium hypochlorite storage tank stores the disinfectant, and the dosing pump injects the disinfectant into the contact reaction tank according to the set dosage. Water in the contact reaction tank comes into full contact with the disinfectant, effectively killing bacteria, viruses, and other pathogens to achieve the purpose of disinfection.

[0070] The ozone disinfection component consists of an ozone generator, an ozone contact tower, and an exhaust gas destroyer. The ozone generator produces ozone gas, which is introduced into the ozone contact tower and mixed with desalinated water to oxidize and decompose organic matter and microorganisms in the desalinated water. The exhaust gas destroyer decomposes unreacted ozone into oxygen to prevent environmental pollution. Ozone has strong oxidizing properties and can quickly react with bacteria, viruses, and other microorganisms, destroying their cell walls, cell membranes, and internal structures, thereby achieving sterilization and disinfection.

[0071] The disinfection device contains different disinfection components, which are preferably used in series. They are rapidly inactivated by ultraviolet light, provided by sodium hypochlorite for continuous disinfection, and strongly oxidized by ozone. By utilizing the characteristics of different disinfection methods, the secondary water source is disinfected more comprehensively and efficiently, thereby improving the disinfection effect.

[0072] The boron removal and filtration device includes a boron removal unit and a filtration unit, used to separate boron from the second treated water source.

[0073] Among them, the boron removal filtration device is a device used to remove boron from the secondary water source and perform filtration. During the seawater desalination process, boron may have a certain impact on human health, so it is necessary to separate boron from seawater through the boron removal filtration device. It usually includes a boron removal unit and a filtration unit. The boron removal unit uses specific adsorbents, ion exchange resins, etc. to react with boron and separate it from the mixed system. The filtration unit performs solid-liquid separation and other operations on the boron-removed material to remove insoluble impurities in order to achieve the required purity and quality requirements.

[0074] The nutrient adjustment device includes a nutrient solution storage tank, a proportioning mixer, and a trace element addition tank. The nutrient solution storage tank stores the nutrient solution, the proportioning mixer mixes the nutrient solution with water in a proportion, and the trace element addition tank adds trace elements as needed.

[0075] Nutrient solution storage tanks are containers used to store nutrient solutions, which typically contain a large number of elements required for plant growth, such as nitrogen, phosphorus, and potassium.

[0076] The proportioning mixer is used to mix solutions of different components in a certain proportion. In this nutrient adjustment device, it can precisely mix the nutrient solution in the nutrient solution storage tank with the trace element solution added from the trace element addition tank to form a nutrient solution of appropriate concentration and proportion according to the needs of plant growth.

[0077] The micronutrient addition container is used to store micronutrient solutions. Although the amount of micronutrients required by plants is relatively small during plant growth, they play a vital role in the normal growth and development of plants. Examples of micronutrients include iron, manganese, zinc, and copper. This addition container can add appropriate amounts of micronutrients to the mixed system according to the actual situation.

[0078] The nutrient regulation device, through the coordinated work of these components, enables the freshwater flowing out after treatment by the nutrient regulation device in the post-treatment system to directly provide a nutrient solution that meets the growth needs of plants. This eliminates the need to repeatedly install treatment facilities at water-using terminals such as water storage wetland systems, agricultural irrigation, and ecological ditches in water-scarce coastal areas, thereby reducing deployment and maintenance costs while meeting water usage standards.

[0079] Each device has an outlet, and connecting pipes are connected to the outlet of the corresponding regulating device according to the water quality standards of the actual application scenario. The post-treatment system aims to deeply treat the desalinated water by setting up structural devices with different functions, so that the treated water can meet the usage standards of various water resource allocation terminals in water-scarce coastal areas, such as industrial water, municipal water supply, water storage wetland systems, agricultural irrigation, and ecological ditch water. This meets the diverse needs of application scenarios and eliminates the need to repeatedly add treatment facilities to each water terminal, achieving the technical effects of simplifying the system structure and reducing deployment and maintenance costs.

[0080] Because boron removal and nutrient regulation are costly, they are only activated when necessary. Industrial / municipal water standards have relatively lenient requirements for boron and nutrients or are guaranteed by subsequent municipal treatment. However, agriculture / ecology requires lower boron content and specific nutrients. Therefore, different treatment devices are deployed in the post-treatment system according to different application scenarios, which helps to reduce the overall cost.

[0081] As one implementation method, when the water terminal is industrial water or municipal water supply, the second treated water source is post-treated by a post-treatment system to form a third treated water source. This can include: introducing the second treated water source into the post-treatment system; adjusting the hardness, pH value and disinfecting the second treated water source through the post-treatment system to form a third treated water source, and then transporting the third treated water source to the industrial water supply network or municipal water supply network.

[0082] It should be noted that industrial water supply networks refer to a network system in the industrial sector consisting of a series of pipes, fittings, valves, and ancillary facilities. Their main function is to transport the second-treated water source, after being processed by the hardness adjustment device, pH adjustment device, disinfection device, and boron removal filtration device of the post-treatment system, to various industrial water use points. Municipal water supply networks are also a network system composed of a series of pipes, fittings, valves, and ancillary facilities. Their main function is to transport the second-treated water source, after being processed by the hardness adjustment device, pH adjustment device, disinfection device, and boron removal filtration device of the post-treatment system, to various areas of the city to meet the water needs of different sectors such as residential life, commercial activities, and public services, in accordance with drinking water standards.

[0083] Furthermore, when the water-using terminal is a water storage wetland system, agricultural irrigation, or ecological ditch, the post-treatment system further treats the second-treated water source to form a third-treated water source. This may include: introducing the second-treated water source into the post-treatment system; adjusting the hardness, pH value, disinfecting, deboronizing, and adjusting the nutrients of the second-treated water source through the post-treatment system to form a third-treated water source; and transporting the third-treated water source to the water storage wetland, agricultural irrigation network, or ecological ditch network.

[0084] Step S104: Based on multiple relevant index parameter data of the third treated water source, determine the stability evaluation coefficient of each water-using terminal.

[0085] Step S105: Determine the overall stability of the system based on the stability evaluation coefficient of each water terminal.

[0086] Specifically, determining the overall stability of the system based on the stability assessment coefficients of each water-using terminal can include: calculating the overall stability by weighted average of the stability assessment coefficients of each water-using terminal; wherein the weights are determined based on the proportion of water consumption and importance of each water-using terminal.

[0087] A mapping relationship can be established to calculate the overall stability M of the processing system. The specific mapping relationship is as follows: ;

[0088] Where n represents the number of water terminals. This represents the stability assessment coefficient of the j-th water terminal; This represents the weight of the j-th water terminal, which is set based on the proportion of water consumption and importance of the water terminal, where j = 1, 2, ..., n, and satisfies... .

[0089] The seawater desalination water resource allocation and processing method provided in this invention involves acquiring a seawater source, pre-treating the seawater source using a pre-treatment system to form a first treated water source, performing reverse osmosis treatment on the first treated water source using a reverse osmosis membrane module to form a second treated water source, and then post-treating the second treated water source using a post-treatment system to form a third treated water source. The third treated water source is then delivered to the corresponding water-using terminals. Based on multiple relevant index parameters of the third treated water source, a stability evaluation coefficient is determined for each water-using terminal, and the overall stability of the system is determined based on the stability evaluation coefficients of each water-using terminal. This method achieves dynamic collaborative evaluation of relevant index parameter data and assesses the overall stability of the system based on the differences in the needs of water-using terminals.

[0090] Example 2

[0091] This invention also provides another method for the allocation and treatment of seawater desalination water resources; this method is implemented based on the method in the above embodiments; this method focuses on describing the specific implementation of determining the stability evaluation coefficient of each water-using terminal based on multiple relevant index parameter data of the third treated water source.

[0092] Figure 2 A flowchart of another seawater desalination water resource allocation and processing method provided in an embodiment of the present invention is shown below. Figure 2 As shown, determining the stability assessment coefficient for each water user terminal based on multiple relevant index parameters of the third treated water source can include the following steps:

[0093] Step S201: Obtain water quality index data, water quantity index data, and system operation index data.

[0094] The water quality indicators include: hardness, pH, boron content, microbial content, and nutrient content.

[0095] The water quality indicators may include: water supply flow stability sub-indicators and water supply pressure stability sub-indicators.

[0096] The system operation metrics data may include: equipment failure rate and energy consumption stability.
