[0003] In the traditional direct drinking water preparation process, the water activation treatment technology is relatively simple, mostly using magnetization treatment or single-frequency electromagnetic wave treatment. The optimization effect on the physical structure of the raw water is limited, resulting in the failure to significantly improve the water molecule cluster structure and limited activation effect, which in turn affects the subsequent purification efficiency.

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] Figure 1 is a schematic diagram of a process for preparing direct drinking water, such as Figure 1 As shown, an embodiment of the present invention provides a method for preparing direct drinking water, comprising the following steps: S1, activating raw water for 10-30 seconds by electromagnetic waves in a frequency range of 20-30 Hz, activating raw water for 10-30 seconds by electromagnetic waves in a frequency range of 30-45 Hz, and activating raw water for 10-30 seconds by electromagnetic waves in a frequency range of 45-60 Hz; S2, pre-filtering the activated water with quartz sand, activated carbon and softener; S3, membrane separation of the pre-filtered water by pressure; S4, filtering the membrane-separated water with a nanofiltration membrane with a pore size of 0.001-0.01 μm; S5, mineralizing the filtered water with a mixture of mineralized particles with a particle size of 0.05 mm; S6, using ozone and ultraviolet disinfection devices to carry out demicrobial treatment, through the synergy of multi-frequency electromagnetic waves, so as to make the activation of raw water more thorough, and also create favorable conditions for subsequent filtration, mineralization and disinfection steps.

[0024] In this embodiment, by gradually acting on water molecules in stages with electromagnetic waves of different frequencies, the hydrogen bonds between water molecule clusters can be effectively destroyed, so that water molecules are dissociated from large cluster structures into small molecule clusters, thereby improving the activity and energy state of water; the activated water molecule structure is more dispersed, the water fluidity is enhanced, and the binding force between impurities and water molecules is reduced, thereby improving the efficiency of pre-filtration and nanofiltration; small molecule cluster water has higher redox activity, which is beneficial to the synergistic effect of ozone and ultraviolet rays, improves the inactivation efficiency of microorganisms, and ensures the safety and stability of water quality.

[0025] It should be noted that water molecules are polar molecules composed of hydrogen atoms and oxygen atoms through covalent bonds. Under the natural state, water molecules will form molecular clusters through hydrogen bonds. This cluster structure is relatively tight and stable, which affects the activity and permeability of water. When electromagnetic waves act on water molecules, the hydrogen bond energy of water molecules will be changed through the energy intervention of the alternating electromagnetic field, thereby gradually breaking up the larger water molecule cluster structure, dissociating it into smaller water molecule aggregates, and improving the activation degree of water.

[0026] Specifically, in the frequency range of 20-30Hz, the energy of electromagnetic waves is relatively low, and it mainly plays a preliminary activation role. Through the weak electromagnetic field, it begins to destroy the hydrogen bonds between larger water molecule clusters, making some molecular structures loose; in the electromagnetic wave frequency range of 30-45Hz, as the frequency increases, the energy of electromagnetic waves gradually increases, further promoting the depolymerization of water molecules. This stage can accelerate the breaking of hydrogen bonds, so that more water molecule clusters dissociate into smaller structures, and improve the fluidity and activity of water molecules; under the action of high-frequency electromagnetic waves of 45-60Hz, the activation of water molecules reaches the optimal state. High-frequency electromagnetic waves have higher energy, which can further reorganize the already loose water molecules to form a uniform and stable small molecule cluster structure, and enhance the permeability and solubility of water. The step-by-step 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 exert different energy levels on water molecules, gradually realizing the process from preliminary depolymerization to deep activation. In addition, the structure of water molecules after activation is more dispersed, which is beneficial to the removal of impurities and ions by the filtration device in the pre-filtration stage; the fluidity of small molecular cluster water is improved, and in the nanofiltration stage, the nanomembrane filtration efficiency is higher and the water quality is purer; during mineralization, the solubility of water molecules is enhanced, and the trace elements in the mineralized particle mixture can be dissolved more fully; the activated water molecules have higher redox activity, and the sterilization effect is better when combined with ozone and ultraviolet disinfection devices.

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

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

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

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

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

[0032] In this embodiment, quartz sand filtration is mainly used to remove larger particles of sediment, suspended matter and other impurities in the water. Coconut shell activated carbon has a high specific surface area and strong adsorption capacity, which can effectively remove organic matter, residual chlorine, odor and some heavy metals in the water. The ion exchange resin in the softener can remove hardness ions such as calcium and magnesium in the water, prevent subsequent equipment such as reverse osmosis membrane from scaling, realize preliminary filtration of water, remove physical impurities, organic matter and hardness ions. It further improves the purity of water quality, provides good water inlet conditions for subsequent reverse osmosis and nanofiltration, prolongs the service life of the filtration equipment, and reduces maintenance costs.

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

[0034] In this embodiment, medical stone and ginger stone are rich in various minerals and trace elements, and can slowly release beneficial ingredients in water. Active calcium carbonate helps to increase the calcium ion concentration in water and improve the taste of water, so as to mineralize the filtered pure water and supplement calcium, magnesium, zinc, selenium and other trace elements necessary for the human body, so as to enhance the biological activity of water and improve the drinking taste.

[0035] Furthermore, the ozone disinfection concentration in step S6 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 / cm 2 .

[0036] In this embodiment, ozone disinfection uses strong oxidizing properties to destroy the cell structure of microorganisms and kill bacteria, viruses, fungi, etc. Ultraviolet disinfection uses the UV-C wavelength of 253.7nm to destroy the DNA or RNA structure of microorganisms and achieve rapid sterilization. The combined use of the two can achieve the complementarity of physical and chemical disinfection, ensure thorough disinfection, eliminate microorganisms and harmful pathogens in water, and ensure the safety and stability of water quality. By providing a dual disinfection effect, microorganisms and harmful substances are effectively removed, and secondary pollution in pipelines and water storage processes is prevented to ensure that the effluent meets the safe direct drinking water standards.

[0037] Figure 2 It is a structural schematic diagram of a direct drinking water preparation device, such as Figure 2 As shown, the embodiment of the present invention also provides a direct drinking water preparation device, including: an energy activation device 12, the energy activation devices are interconnected, and are used to activate water through a predetermined frequency; a pre-filtration device 13, used to pre-filter water through quartz sand, activated carbon and a softener; a reverse osmosis device 14, used to perform membrane separation on water through 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 mineralized particles of a certain particle size; a soda 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 rays to disinfect water; a water storage tank 20, used to store purified water. In addition, it also 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 generates electromagnetic waves of a specific frequency through high-frequency alternating current, and the electromagnetic waves are transmitted to the water flow through the transmission medium in the device, such as an electromagnetic coil or a crystal oscillator, to form a uniform electromagnetic field that acts on water molecules. In addition, the device is equipped with multiple sensors to monitor the conductivity, pH value, temperature and other parameters of water quality in real time, so as to automatically adjust the electromagnetic field strength and frequency according to changes in water quality to ensure the stability of each treatment effect.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
