Technical Field

[0001] This invention relates to a method and apparatus for preparing direct drinking water. Background Technology

[0002] As people's living standards improve, the demand for healthy drinking water is gradually increasing, and direct drinking water has become an important form of water supply in modern homes, offices, and public areas. Direct drinking water is characterized by its clean water quality and direct potability, effectively avoiding secondary pollution and meeting the human body's need for safe and healthy drinking water.

[0003] In traditional direct drinking water preparation processes, the water activation technology is relatively simple, often employing magnetization or single-frequency electromagnetic wave treatment. This has limited effect on optimizing the physical structure of the raw water, resulting in a failure to significantly improve the water molecule cluster structure and thus limiting the activation effect, which in turn affects the subsequent purification efficiency.

[0004] Therefore, how to improve water activation treatment technology is a technical problem that needs to be solved. Summary of the Invention

By using multi-frequency electromagnetic wave activation to enhance the activation effect, and in conjunction with subsequent steps, a highly efficient, energy-saving, and environmentally friendly method for preparing direct drinking water is achieved. This invention achieves its purpose as follows:

[0006] In one aspect, the present invention provides a method for preparing direct drinking water, comprising the following steps: S1, activating raw water for 10-30 seconds using electromagnetic waves with a frequency range of 20-30Hz, activating raw water for 10-30 seconds using electromagnetic waves with a frequency range of 30-45Hz, and activating raw water for 10-30 seconds using electromagnetic waves with a frequency range of 45-60Hz; S2, pre-filtering the activated water using quartz sand, activated carbon, and a water softener; S3, performing membrane separation on the pre-filtered water using pressure; S4, filtering the membrane-separated water using a nanofiltration membrane with a pore size of 0.001-0.01μm; S5, mineralizing the filtered water using a mixture of mineralized particles with a particle size of 0.05mm; S6, performing microbial treatment using an ozone and ultraviolet disinfection device.

[0007] Furthermore, the activation of the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 20-30Hz includes: activating the raw water for 20 seconds using an alternating electromagnetic field with a frequency range of 20-30Hz, wherein the electromagnetic field strength is controlled at 5mT.

[0008] Furthermore, during the electromagnetic wave activation process, micro-vibrations are applied to the raw water at a frequency of 10-20Hz.

[0009] Furthermore, the activation of the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 30-45Hz includes: activating the raw water for 25 seconds using an alternating electromagnetic field with a frequency range of 30-45Hz, with the electromagnetic field strength controlled at 10mT.

[0010] Furthermore, the activation of the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 45-60Hz includes: activating the raw water for 30 seconds using an alternating electromagnetic field with a frequency range of 45-60Hz, wherein the electromagnetic field strength is controlled at 15mT.

[0011] Furthermore, in step S2, the particle size of the quartz sand ranges from 0.5 to 1.0 mm, and the activated carbon is selected from coconut shells, with a surface area of ​​800-1200 m². 2 / g, the softener uses ion exchange resin with an exchange capacity of 1.8-2.5 mmol / g.

[0012] Furthermore, the mineralized particle mixture in step S5 comprises the following components by weight percentage: 35-45% maifanite, 40-50% ginger stone, and 5-10% active calcium carbonate.

[0013] Furthermore, in step S6, the ozone disinfection concentration is 0.3-0.8 mg / L, the disinfection contact time is 5-10 minutes, the ultraviolet wavelength of the ultraviolet disinfection device is 253.7 nm, and the ultraviolet dose is 30-60 mJ / cm². 2 .

[0014] In another aspect, the present invention provides a direct drinking water preparation device, comprising: an energy activation device interconnected with each other for activating water at a predetermined frequency; a pre-filtration device for pre-filtration of water using quartz sand, activated carbon, and a softener; a reverse osmosis device for membrane separation of water using pressure; a nanofiltration device for filtering water using a nanofiltration membrane with a certain pore size; a mineralizer for mineralizing the filtered water using a mixture of mineral particles of a certain particle size; a soda-water mixer for mixing ozone and water; an ozone generator for generating ozone; an ultraviolet disinfection device for generating ultraviolet light to disinfect the water; and a water storage tank for storing the purified water.

[0022] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0023] Figure 1 This is a flowchart illustrating a method for preparing direct drinking water, such as... Figure 1 As shown, this embodiment of the invention provides a method for preparing direct drinking water, including the following steps: S1, activating the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 20-30Hz, activating the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 30-45Hz, and activating the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 45-60Hz; S2, pre-filtering the activated water using quartz sand, activated carbon, and a water softener; S3, performing membrane separation on the pre-filtered water using pressure; S4, filtering the membrane-separated water using a nanofiltration membrane with a pore size of 0.001-0.01μm; S5, mineralizing the filtered water using a mixture of mineralized particles with a particle size of 0.05mm; S6, using an ozone and ultraviolet disinfection device for microbial treatment. The synergistic effect of multiple frequency electromagnetic waves ensures more thorough activation of the raw water and creates favorable conditions for subsequent filtration, mineralization, and disinfection steps.

[0024] In this embodiment, by applying electromagnetic waves of different frequencies in stages to water molecules, the hydrogen bonds between water molecule clusters can be effectively broken, causing water molecules to dissociate from large clusters into smaller clusters, thereby enhancing the activity and energy state of the water. The activated water molecule structure is more dispersed, the water flow is enhanced, and the binding force between impurities and water molecules is reduced, thus improving the efficiency of pre-filtration and nanofiltration. Small molecule cluster water has higher redox activity, which is conducive to the synergistic effect of ozone and ultraviolet light, improving the inactivation efficiency of microorganisms and ensuring the safety and stability of water quality.

[0025] It should be noted that water molecules are polar molecules composed of hydrogen and oxygen atoms through covalent bonds. In their natural state, water molecules form molecular clusters through hydrogen bonds. These clusters are relatively compact and stable, affecting the activity and permeability of water. When electromagnetic waves act on water molecules, the energy intervention of the alternating electromagnetic field changes the hydrogen bond energy of the water molecules, thereby gradually breaking down the larger water molecule clusters and dissociating them into smaller water molecule aggregates, thus increasing the activation level of water.

[0026] Specifically, in the 20-30Hz frequency range, electromagnetic waves have relatively low energy and mainly play a preliminary activation role. Through the action of a weak electromagnetic field, they begin to break the hydrogen bonds between larger water molecule clusters, causing some molecular structures to loosen. In the 30-45Hz frequency range, as the frequency increases, the energy of the electromagnetic waves gradually increases, further promoting the deagglomeration of water molecules. This stage can accelerate the breaking of hydrogen bonds, causing more water molecule clusters to dissociate into smaller structures, improving the fluidity and activity of water molecules. Under the action of high-frequency electromagnetic waves (45-60Hz), the activation of water molecules reaches its optimal state. High-frequency electromagnetic waves have high energy and can further recombine the already loosened water molecules, forming uniform and stable small molecular cluster structures, enhancing the permeability and dissolving capacity of water. The stepwise action of multi-frequency electromagnetic waves can effectively overcome the defect of unstable activation effect of single-frequency electromagnetic waves. Electromagnetic waves of different frequencies apply different energy levels of intervention to water molecules, gradually realizing the process from initial deagglomeration to deep activation. Furthermore, the activated water molecules are more dispersed, which is beneficial for the removal of impurities and ions by the pre-filtration stage; the increased fluidity of the small molecule clusters makes the nanofiltration membrane more efficient and the water purer during the nanofiltration stage; during mineralization, the solubility of water molecules is enhanced, and trace elements in the mineralized particle mixture can be dissolved more fully; the activated water molecules have higher oxidation-reduction activity, which, combined with ozone and ultraviolet disinfection devices, results in better sterilization.

[0027] Furthermore, the activation of the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 20-30Hz includes: activating the raw water for 20 seconds using an alternating electromagnetic field with a frequency range of 20-30Hz, with the electromagnetic field strength controlled at 5mT, thereby further increasing the activation effect.

[0028] Optionally, during the electromagnetic wave activation process, the raw water is subjected to micro-vibrations at a frequency of 10-20Hz to further enhance the activation effect.

[0029] Furthermore, the activation of the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 30-45Hz includes: activating the raw water for 25 seconds using an alternating electromagnetic field with a frequency range of 30-45Hz, with the electromagnetic field strength controlled at 10mT, thereby further increasing the activation effect.

[0030] Furthermore, the activation of the raw water for 10-30 seconds using electromagnetic waves with a frequency range of 45-60Hz includes: activating the raw water for 30 seconds using an alternating electromagnetic field with a frequency range of 45-60Hz, with the electromagnetic field strength controlled at 15mT, thereby further increasing the activation effect.

[0031] Furthermore, in step S2, the particle size range of the quartz sand is 0.5-1.0 mm, and the activated carbon is coconut shell activated carbon with a surface area of ​​800-1200 m². 2 / g, the softener uses ion exchange resin with an exchange capacity of 1.8-2.5 mmol / g.

[0032] In this embodiment, quartz sand filtration is mainly used to remove larger particles of silt, suspended solids, and other impurities from the water. Coconut shell activated carbon, with its high specific surface area and strong adsorption capacity, can effectively remove organic matter, residual chlorine, odors, and some heavy metals from the water. The ion exchange resin in the softener can remove hardness ions such as calcium and magnesium from the water, preventing scaling in subsequent equipment such as the reverse osmosis membrane. This achieves preliminary filtration of the water, removing physical impurities, organic matter, and hardness ions. This further improves the purity of the water, providing excellent inlet conditions for subsequent reverse osmosis and nanofiltration, extending the service life of the filtration equipment, and reducing maintenance costs.

[0033] Furthermore, the mineralized particle mixture in step S5 comprises the following components by weight percentage: 35-45% maifanite, 40-50% ginger stone, and 5-10% activated calcium carbonate.

[0034] In this embodiment, maifan stone and ginger stone are rich in various minerals and trace elements, which can slowly release beneficial components in water. Activated calcium carbonate helps to increase the concentration of calcium ions in the water and improve the taste of the water, so as to mineralize the filtered pure water and supplement the essential trace elements such as calcium, magnesium, zinc, and selenium, thereby improving the biological activity of the water and improving the drinking taste.

[0035] Furthermore, in step S6, the ozone disinfection concentration is 0.3-0.8 mg / L, the disinfection contact time is 5-10 minutes, the ultraviolet wavelength of the ultraviolet disinfection device is 253.7 nm, and the ultraviolet dose is 30-60 mJ / cm². 2 .

[0036] In this embodiment, ozone disinfection utilizes strong oxidizing properties to destroy the cell structure of microorganisms, killing bacteria, viruses, fungi, etc., while ultraviolet disinfection uses a 253.7nm UV-C wavelength to destroy the DNA or RNA structure of microorganisms, achieving rapid sterilization. The combined use of both achieves complementary physical and chemical disinfection, ensuring thorough disinfection, eliminating microorganisms and harmful pathogens in the water, and guaranteeing the safety and stability of water quality. By providing a dual disinfection effect, it effectively removes microorganisms and harmful substances while preventing secondary pollution during pipeline and water storage processes, ensuring that the effluent meets safe drinking water standards.

[0037] Figure 2 This is a schematic diagram of a direct drinking water preparation device, such as... Figure 2 As shown in the figure, this embodiment of the invention also provides a direct drinking water preparation device, including: an energy activation device 12, which are interconnected and used to activate water at a predetermined frequency; a pre-filtration device 13, used to pre-filter water using quartz sand, activated carbon, and a softener; a reverse osmosis device 14, used to perform membrane separation of water under pressure; a nanofiltration device 15, used to filter water using a nanofiltration membrane with a certain pore size; a mineralizer 16, used to mineralize the filtered water using a mixture of mineral particles of a certain particle size; a soda-water mixer 17, used to mix ozone and water; an ozone generator 18, used to generate ozone; an ultraviolet disinfection device 19, used to generate ultraviolet light to disinfect water; and a water storage tank 20, used to store the purified water. Additionally, it includes a raw water tank 11 for providing raw water.

[0038] Furthermore, the energy activation device 12 includes: an electromagnetic field generator for generating electromagnetic waves of a certain frequency through high-frequency alternating current; and a vibration device for generating vibrations of a certain frequency through a vibration device or an ultrasonic device.

[0039] Specifically, the electromagnetic field generator produces electromagnetic waves of a specific frequency using high-frequency alternating current. These waves are transmitted into the water flow through a transmission medium within the device, such as an electromagnetic coil or crystal oscillator, forming a uniform electromagnetic field that acts on the water molecules. Additionally, the device is equipped with multiple sensors to monitor water quality parameters such as conductivity, pH value, and temperature in real time. This allows for automatic adjustment of the electromagnetic field strength and frequency based on changes in water quality, ensuring the stability of the treatment effect each time.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
