[0004] Electricity mainly comes from the power grid. However, if wastewater and sewage electrolysis equipment (devices) rely entirely on power supply from the power grid, additional equipment investment (such as transformers, high and low voltage distribution cabinets, wires and cables, DC power supplies, etc.) will be required, which will not only increase costs but also impose a greater burden on the power resources of the power grid.

[0016] The following is combined with Figure 1 The utility model is further described.

[0017] In order to solve the problems existing in the background technology, the present application proposes the following technical scheme: a wastewater electrolysis device using photovoltaic power generation and direct-connected electrodes. In the specific technical scheme, it includes a photovoltaic panel 1, a connecting wire line 4, an electric control device 5, an electric quantity statistics module 3, a time relay 6, a water quality detection device 8 and an electrolytic water tank 9, a drainage solenoid valve 10, a water inlet solenoid valve 14, a first electrolytic anode 7 and a first electrolytic cathode 11. The bottom of the photovoltaic panel 1 is fixedly connected with a bracket 2, and the first electrolytic anode 7 and the second electrolytic electrode are located in the electrolytic water tank 9. The photovoltaic panel 1 generates current through light, and the current passes through the negative electrode 12 of the photovoltaic panel 1, the positive electrode 13 of the photovoltaic panel 1, and the connecting wire line 4, and flows into the cathode of the first electrolytic cathode 11 and the first electrolytic anode 7 respectively. The connecting wire line 4 refers to all electrically coupled wires in the figure, and is not limited to the specific positions indicated in the figure.

At least one group of photovoltaic panels 1, one group of first electrolysis anodes 7 and first electrolysis cathodes 11, one group of electric control devices 5, one group of power statistics modules 3, a time relay 6 and a water quality detection device 8 are provided. The electrolytic water tank 9 is provided with a drainage solenoid valve 10 and a water inlet solenoid valve 14, and the electrolytic water tank 9 is provided with a liquid level meter.

[0018] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0019] When in use, the photovoltaic panel 1 generates current through light, and the current passes through the negative electrode 12 of the photovoltaic panel 1, the positive electrode 13 of the photovoltaic panel 1, and the connecting wire line 4, and flows into the first electrolytic cathode 11 and the first electrolytic anode 7 respectively.

[0020] The wastewater undergoes an electrochemical reaction under the action of the electric current. At the same time, the current generated by the photovoltaic panel 1 is shunted to the power statistics module 3 to count the electricity generated by the photovoltaic panel. At the same time, the time relay 6 starts the electrolysis timing, and the water quality detection device 8 detects the water quality treatment status online. At this time, the drainage solenoid valve 10 is in a closed state.

[0021] After the wastewater is electrolyzed for a certain period of time, the power statistics module 3 reaches a preset value, or the time relay 6 reaches a preset value, or the water quality detection device 8 reaches a preset value, the electronic control device 5 controls the drainage solenoid valve 10 to open, and the wastewater in the electrolytic water tank 9 reaches the pretreatment effect and is discharged to other tanks or equipment. A liquid level meter is provided in the electrolytic water tank 9 for counting the liquid level. When the liquid level reaches a preset value, the drainage solenoid valve 10 is closed, and the water inlet solenoid valve 14 starts to inlet water. When the liquid level reaches a preset value, the water inlet solenoid valve 14 is closed, and the device performs the next electrolysis cycle.

[0022] The concept of wastewater electrolysis: The process of using electrolysis to remove or recover certain substances in wastewater is called wastewater electrolysis.

[0023] Principle of wastewater electrolysis: During the electrolysis process, anions in the wastewater move toward the anode and release electrons to the anode (oxidation reaction); cations move toward the cathode and receive electrons from the cathode (reduction reaction). The gain and loss of electrons during the reaction is called discharge.

[0024] When an aqueous solution is electrolyzed, oxidation occurs at the anode to generate oxygen, and reduction occurs at the cathode to generate hydrogen. These two types of reactions carried out in the same electrolytic cell can be used to treat various wastewaters (sewage).

[0025] The basic principle of wastewater electrolysis is:

[0026] (1) Electrolytic oxidation: The electrolytic process of eliminating certain pollutants by using the anodic oxidation reaction. For example, for high-concentration cyanide-containing wastewater, the anodic oxidation reaction is used to convert cyanide into cyanate, and the cyanate is further oxidized into nitrogen and carbon dioxide. The reaction process is as follows:

[0027] CN-+2OH-→CNO-+H2O+2e(1)

[0028] 2CNO-+4OH-→2CO2+N2+2H2O+6e(2)

[0029] If the electrolytic oxidation of reaction (2) is not sufficient, chlorine or hypochlorite can be added to completely oxidize the cyanate.

[0030] (2) Electrolytic reduction: The hydrogen produced at the cathode can cause certain substances to undergo a reduction reaction and eliminate pollution. For example, when electrolyzing chromium-containing wastewater, the ferrous ions dissolved from the soluble anode iron plate can reduce the hexavalent chromium in the wastewater to trivalent chromium. The discharge of cathode hydrogen ions reduces the number of hydrogen ions, and the wastewater tends to be alkaline, making it easy for chromium hydroxide (trivalent chromium) and trivalent iron to precipitate.

[0031] (3) Electrolytic flotation: When the hydrogen and oxygen generated by the cathode and anode in the process of electrolysis of aqueous solution escape from the water in the form of tiny bubbles, they are adsorbed on the suspended matter in the wastewater and float to the water surface together to form scum, which can be skimmed off.

[0032] (4) Electrolytic coagulation: During the electrolysis process, iron and aluminum plates are used as anodes to dissolve iron and aluminum in the electrolyte in an ionic state. After hydrolysis, they are hydrolyzed into hydroxyl complexes and converted into substances with coagulation effects, such as Al(OH)3, Fe(OH)3, etc. Such substances can neutralize the charges of particulate matter and colloidal matter, facilitating coagulation.

[0033] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0034] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that the scope of the present invention is defined by the appended claims and their equivalents.
