[0048] The technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application.

[0049] Figure 2Shown is a flow chart of a water purification method provided by an embodiment of the present application. Figure 2 As shown, the water purification method provided in the embodiment of the present application includes the following steps S21 to S25.

[0050] S21, obtaining an initial water source to be purified.

[0051] Specifically, the initial water source to be purified may be: surface water, groundwater, recycled water, etc., wherein the recycled water may include: urban wastewater, industrial wastewater, etc. treated by a sewage treatment plant.

[0052] It should be noted that the above-listed initial water sources to be purified are only used for illustrative purposes. In practical applications, any other suitable water source may be selected according to actual conditions, and this application does not impose any limitation on this.

[0053] Exemplary methods of obtaining the initial water source to be purified may be: directly extracting the initial water source from surface water bodies such as rivers, lakes, reservoirs, or through wells or springs, using wastewater collected by sewer systems or special collection facilities as the initial water source, or using seawater pumped near the coastline as the initial water source.

[0054] It should be noted that the above method of obtaining the initial water source to be purified is only for illustrative purposes. In practical applications, any other suitable method of obtaining the initial water source to be purified can be selected according to actual conditions, and this application does not impose any restrictions on this.

[0055] S22, inputting the initial water source into a water purification module.

[0056] Among them, the water purification module is used to purify the initial water source.

[0057] Exemplarily, the initial water source may be input into the water purification module based on pumping input, pressure input, manual input, etc., wherein pumping input refers to pumping the initial water source into the water purification module based on a water pump, pressure input refers to delivering the initial water source to the water purification module based on a pressure pipe system, and manual input refers to delivering the initial water source to the water purification module by manual operation without the aid of automated equipment or electricity. In actual applications, any of the above three methods of inputting the initial water source into the water purification module may be selected based on different water purification application scenarios.

[0058] It should be noted that the above-mentioned methods of inputting the initial water source into the water purification module are only for illustrative purposes. In actual applications, any other suitable methods can be selected according to the specific application scenario, and this application does not impose any limitation on this.

[0059] S23, based on a photocatalytic method, irradiating a light source to a catalyst so that electron-hole pairs are generated on the surface of the catalyst, wherein the electron-hole pairs are composed of electrons and holes.

[0060] The catalyst may be a functionalized catalyst. Specifically, a functionalized catalyst is obtained by introducing a functional group, such as a hydroxyl radical (·OH), on the catalyst surface. The functionalized catalyst can enhance its interaction with specific organic pollutants in the initial water source and improve the removal efficiency of organic pollutants in the initial water source.

[0061] Exemplarily, the catalyst can be any one of titanium dioxide (TiO2), iron oxide (Fe2O3), vanadium pentoxide (V2O5), zinc oxide (ZnO), magnesium oxide (MgO), aluminum oxide (Al2O3), silicon dioxide (SiO2), etc.

[0062] For example, taking TiO2 as the catalyst, when light irradiates TiO2, electron-hole pairs are generated on the surface of TiO2.

[0063] It should be noted that the types of catalysts listed in the above catalyst examples are only for illustrative purposes. In practical applications, any other suitable catalyst can be selected according to actual conditions, and this application does not impose any limitation on this.

[0064] S24, obtaining a strong oxidizing substance based on the holes and water molecules.

[0065] Among them, strong oxidizing substances refer to hydroxyl radicals (·OH), hydroperoxyl radicals (·HO2), singlet oxygen ( 1 O2), superoxide anion radical (O2 - )wait.

[0066] Among them, the expression for the reaction between holes and water molecules to generate hydroxyl radicals is: h++H2O→·OH+H+, where h+ represents holes and H+ represents hydrogen ions.

[0067] S25, based on the strong oxidizing substance, decomposing the pollutants in the initial water source in the water purification module to obtain the target water source after purification by the water purification module.

[0068] The organic pollutants in the initial water source include one or more of benzene, toluene, polycyclic aromatic hydrocarbons (PAHs), dyes, etc.

[0069] For example, taking hydroxyl radicals as an example, hydroxyl radicals attack the chemical bonds of organic pollutants in the initial water source through their strong oxidizing ability, breaking the chemical bonds of organic pollutants, thereby decomposing pollutants into smaller, harmless or more easily biodegradable molecules, such as carbon dioxide and water. After the organic pollutants in the initial water source are purified by hydroxyl radicals, the target water source after purification is obtained.

[0070] Exemplarily, R-H+·OH→R·+H2O represents the reaction formula of organic pollutants in the initial water source with hydroxyl radicals, wherein RH represents the general term for organic pollutants in the initial water source, and "R" in R· represents a general symbol representing any alkyl group.

[0071] It should be noted that, in addition to the types of organic pollutants in the initial water source listed above, the organic pollutants in the initial water source may also include other types of organic pollutants, which are not limited in this application.

[0072] It should be noted that all organic molecules containing hydrogen atoms in the organic pollutants in the initial water source can be removed by the above method. The specific reaction formula is similar to the above implementation steps, and this application will not go into details.

[0073] In the water purification method provided in the embodiment of the present application, an initial water source to be purified is obtained; the initial water source is input into a water purification module; based on a photocatalytic method, a light source is irradiated on a catalyst so that electron-hole pairs are generated on the surface of the catalyst, wherein the electron-hole pairs are composed of electrons and holes; based on the holes and water molecules, a strong oxidizing substance is obtained; based on the strong oxidizing substance, pollutants in the initial water source are decomposed in the water purification module to obtain a target water source after purification by the water purification module. In the process of purifying the initial water source, the catalyst is irradiated with light to purify the initial water source, and the process of removing organic pollutants in the initial water source is more green and environmentally friendly, which greatly reduces energy consumption. The strong oxidizing substance obtained based on the catalyst can convert organic pollutants in the initial water source into carbon dioxide and water, thereby reducing secondary pollution and reducing the possibility of environmental pollution in the process of purifying the initial water source.

[0074] Figure 3 Shown is another flow chart based on a water purification method in one embodiment of the present application. Figure 3 As shown, another water purification process in the embodiment of the present application includes the following steps S31 to S32.

[0075] S31, forming an electric field in the electrocatalytic reactor by at least one of adding an external voltage and presetting electrode materials.

[0076] Among them, the method of forming an electric field in the electrocatalytic reactor by adding an external voltage includes: setting two electrodes in the electrocatalytic reactor, namely an anode and a cathode, and applying an external voltage between the two electrodes to form an electric field between the two electrodes.

[0077] In addition, electrode materials with different work functions (i.e., the potential of the material) can be used to form an electric field without an applied voltage. For example, when a preset electrode material with a lower potential is used in combination with a preset electrode material with a higher potential, a potential difference will naturally form between them, thereby generating an electric field.

[0078] Specifically, in the electrocatalytic reactor, the electric field is formed by interface effect, electrolyte solution and other methods.

[0079] It should be noted that the above-mentioned different methods of forming an electric field are only for illustrative purposes. In practical applications, any other suitable method of constructing an electric field may be selected according to the specific application scenario, and the present application does not impose any limitation on this.

[0080] S32, accelerating the separation and transfer of the electrons and the holes in the electric field in an electrocatalytic manner.

[0081] Each electron-hole pair consists of an electron and a hole.

[0082] Specifically, after electron-hole pairs are generated on the surface of the catalyst based on a photocatalytic method, in order to further accelerate the separation of electrons and holes, an electrocatalytic method is introduced to accelerate the separation and transfer of the electrons and holes in the electric field.

[0083] For example, in an electric field based on an applied voltage, the electric field can promote the electrons on the surface of the catalyst to be transferred to the cathode, and simultaneously transfer the holes on the surface of the catalyst to the anode, thereby accelerating the separation of electron-hole pairs.

[0084] As another example, in an electric field based on the preset electrode material composition, electrons can be driven to move from the low-potential preset electrode material to the high-potential preset electrode material, thereby promoting the separation of electron-hole pairs.

[0085] Another water purification method provided in an embodiment of the present application includes forming an electric field in the electrocatalytic reactor by adding at least one of an external voltage and a preset electrode material; accelerating the separation and transfer of the electrons and the holes in the electric field based on electrocatalysis, and under electrocatalysis, a larger number of holes can be obtained within a limited time, thereby increasing the separation rate of electron-hole pairs, providing more holes for the subsequent acquisition of strong oxidizing substances, and ultimately shortening the time for initial water source purification and improving the purification efficiency of the initial water source.

[0086] Figure 4 Shown is a flow chart for determining a target water source in one embodiment of the present application. Figure 4 As shown, the process of determining the target water in the embodiment of the present application includes the following steps S41 to S43.

[0087] S41, detecting the water quality of the water source after the first purification treatment by the water purification module.

[0088] Exemplarily, the initial water quality of the initial water source after the first purification treatment by the water purification module can be detected based on water quality detection tools such as gas chromatography, high performance liquid chromatography, online water quality monitor, portable water quality detector, etc.

[0089] It should be noted that the water quality detection tools listed above for detecting the initial water quality are only used for illustrative purposes. In practical applications, any other suitable water quality detection tools can be selected according to actual needs, and this application does not impose any restrictions on this.

[0090] In some embodiments, the water purification module further includes a solar photovoltaic unit, which is connected to the electrocatalytic reactor to provide electrical energy to the electrocatalytic reactor.

[0091] Specifically, the solar photovoltaic unit can convert solar energy into electrical energy, and provide electrical energy for the electrocatalytic reactor based on the solar photovoltaic unit. Compared with traditional fossil fuels, nuclear energy, etc., the solar photovoltaic unit in this application greatly reduces energy consumption, realizes green and environmentally friendly energy provision, and avoids environmental pollution.

[0092] In some embodiments, the electrocatalytic reactor further includes a power storage unit, and the power storage unit is used to store the electrical energy converted by the solar photovoltaic unit.

[0093] Among them, the power storage unit includes: battery unit, battery management system, thermal management system, safety device, etc.

[0094] Specifically, the solar photovoltaic unit supplies the electric energy converted from solar energy to the electrocatalytic reactor, so that the electrocatalytic reactor can perform the steps of accelerating the separation and transfer of the electrons and the holes in the electric field in an electrocatalytic manner. The solar photovoltaic unit stores the excess electric energy after supplying the electric energy converted from solar energy to the electrocatalytic reactor in the power storage unit, which is used to provide electric energy to the electrocatalytic reactor when there is no sun, such as on rainy days or at night.

[0095] In some embodiments, the method further includes: performing an oxidation-reduction reaction on the initial water source in the electrocatalytic reactor based on the electrical energy and the catalyst to obtain the target water source.

[0096] Exemplarily, the reaction formula corresponding to the redox reaction may be:

[0097] For example, when a photon with an energy of hv or a photon with an energy greater than the semiconductor bandgap width Eg is incident on a semiconductor, an electron is excited from the valence band (VB) to the conduction band (CB), thereby generating a highly active electron (eˉ) in the conduction band and leaving a hole (h+) in the valence band, forming a redox system. Dissolved oxygen and water interact with the electrons and holes, ultimately generating highly active hydroxyl groups. ·OH, O2 ˉ 、OOH ˉ Free radicals have strong oxidizing properties and can degrade most organic pollutants adsorbed on the surface of TiO2 into CO2 and H2O, and oxidize or reduce inorganic pollutants into harmless substances.

[0098] See also Figure 5 , Figure 5 Shown is a schematic diagram of a water purification module in one embodiment of the present application, and its specific implementation steps are similar to the methods or steps in the above-mentioned embodiments, which will not be repeated in this application.

[0099] S42: If the water quality of the purified water source is within the water quality data range corresponding to the preset water quality, the water source after the first purification treatment is directly used as the target water source.

[0100] Among them, the preset water quality means the water quality that meets the environmental protection requirements.

[0101] For example, if the data types of water quality data corresponding to the preset water quality include: chemical oxygen demand (COD), biochemical oxygen demand (BOD), total organic carbon (TOC), ammonia nitrogen (NH3-N), nitrate (NO3-N), phosphate (PO4 3- -P), etc. Among them, the preset range of chemical oxygen demand in the preset water quality is 10-30mg / L, the preset range of biochemical oxygen demand is 5-15mg / L, the preset range of total organic carbon is 1-5mg / L, the preset range of ammonia nitrogen is 0.5-2mg / L, the preset range of nitrate is 10-30mg / L, and the preset range of phosphate is 0.05-0.15mg / L. If the initial water quality of the initial water source after the first purification treatment is detected by the water quality detection tool, the various water quality data obtained are all within the preset range of the various water quality data corresponding to the above-mentioned preset water quality, then the initial water source after the first purification treatment corresponding to the initial water quality is directly used as the target water source.

[0102] S43, if the water quality of the water source after purification is not within the water quality data range corresponding to the preset water quality, the water source after purification is input into the water purification module again for purification, until the water quality of the water source after purification by the water purification module is within the water quality data range corresponding to the preset water quality, and the water source obtained after the last purification by the water purification module is used as the target water source.

[0103] Exemplarily, if the initial water quality of the initial water source after the first purification treatment is detected by the water quality detection tool, and at least one item in the first detection data obtained is not within the preset range of the water quality data corresponding to the above-mentioned preset water quality, then the initial water source after the first purification treatment is input into the water purification module again, and the initial water source after the first purification treatment is subjected to a second purification treatment in the water purification module. The process of the second purification treatment is similar to the process of the first purification treatment mentioned above, and the present application will not repeat it here.

[0104] After the water purification module performs the second purification treatment, the water quality detection tool re-detects the initial water source after the second purification treatment to obtain the second detection data corresponding to the initial water source after the second purification treatment, and compares the second detection data with the above-mentioned preset detection data to determine whether the various water quality data in the second detection data are within the water quality data range corresponding to the preset water quality. If the various water quality data in the second detection data are all within the water quality data range corresponding to the preset water quality, the initial water source after the second purification treatment is used as the target water source. On the contrary, if at least one of the various water quality data in the second detection data is not within the water quality data range corresponding to the preset water quality, the initial water source after the second purification treatment is input into the water purification module again for the third water purification treatment, and so on, until the water quality data corresponding to the initial water quality is within the water quality data range corresponding to the preset water quality, the step of inputting the purified initial water source into the water purification module again is stopped to obtain the target water source. Among them, in this application, the number of times the initial water source is purified in the water purification module is not limited.

[0105] See 6, Figure 6 It is shown as another flow chart for determining the target water source in one embodiment of the present application. The specific implementation steps are similar to the methods or steps in the above embodiments, and the present application will not repeat them here.

[0106] In the method for determining the target water source provided by the embodiment of the present application, after the initial water source is purified in the water purification module each time, the water quality detection tool will detect the initial water source after the water purification module is purified to obtain the detection result. If the water quality of the water source after the purification treatment is not within the water quality data range corresponding to the preset water quality, the water source after the purification treatment is input into the water purification module again for purification treatment until the water quality of the water source after the purification treatment of the water purification module is within the water quality data range corresponding to the preset water quality, and the water source obtained after the last purification treatment of the water purification module is used as the target water source. Among them, the water purification module does not limit the number of times the initial water source is purified, and the water quality detection tool will detect the initial water source after each purification of the water purification module, so as to ensure that the purified target water source meets the environmental protection standards and prevent the potential secondary environmental pollution risk caused by incomplete purification of the initial water source.

All solutions implemented by adding, reducing or replacing steps in the prior art based on the principles of the present application are included in the protection scope of the present application.

[0113] The strong oxidizing substance acquisition module 74 is used to obtain strong oxidizing substances based on the holes and water molecules.

[0114] The target water source acquisition module 75 is used to purify the initial water source in the water purification module based on a catalyst to obtain the target water source after purification by the water purification module.

[0115] Among them, the structures and principles of the water source acquisition module 71, the water source transmission module 72, the catalytic module 73, the strong oxidizing substance acquisition module 74, and the target water source acquisition module 75 correspond one by one to the steps in the above-mentioned water purification method, so they are not repeated here.
