[0026] Example 1
[0027] See also Figure 1-Figure 4 As shown, this embodiment provides a novel electrolytic dephosphorization device, including an electrolytic tower 1 and pillars installed at equal intervals at the bottom of the electrolytic tower 1, the bottom of the electrolytic tower 1 is arc-shaped, an electric exhaust valve is installed at the bottom of the electrolytic tower 1, and a high-frequency pulse automatic reversing power supply 2 is installed on one side of the electrolytic tower 1. The high-frequency pulse automatic reversing power supply 2 has a domestic advanced high-frequency switching power supply computer remote distributed (centralized) control system, a built-in PLC is connected to the computer, and a communication network is formed. It has a remote computer Windows human-machine interface control or a touch screen human-machine control interface, which has the advantages of intuitive and convenient operation, high-quality DC pulse output, strong reliability, high efficiency, automatic reversing of the plate, and power consumption of only one-third of the installed power. A water retaining plate 3 is installed on the upper side of the electrolytic tower 1, and the water retaining plate 3 can effectively prevent water from splashing out of the device due to water flow impact, stirring or other operations during the electrolytic dephosphorization process. This can ensure the safety of the working area and avoid pollution to the environment. A degradation component 4 is provided on the upper side of the water retaining plate 3, and the degradation component 4 degrades COD. An oscillation component 5 is installed at the bottom of the inner cavity of the electrolytic tower 1, and the oscillation component 5 is used to clean the flocculent precipitate.
[0028] The oscillation component 5 includes a fixed plate fixedly installed on one side wall of the pillar, and a drive motor 51 is installed on the upper side of the fixed plate. The fixed plate supports the drive motor 51 to ensure that the drive motor 51 remains in a stable state during operation. The output shaft of the drive motor 51 is installed with a second connecting shaft 52, and the second connecting shaft 52 extends to the inner cavity of the electrolytic tower 1. When the drive motor 51 is started, the drive motor 51 drives the second connecting shaft 52 to rotate. The end of the second connecting shaft 52 away from the drive motor 51 is connected to a half gear 53. Driven by the second connecting shaft 52, the half gear 53 performs the same movement as the second connecting shaft 52, that is, the half gear 53 starts to rotate.
[0029] The toothed plates 54 are symmetrically mounted on the opposite side walls of the half gear 53, and the bottom of the toothed plates 54 are all mounted with impact balls. The half gear 53 is in meshing state with the toothed plate 54 on one side, and the impact ball at the bottom of the toothed plate 54 on the other side is in contact with the bottom of the electrolytic tower 1. When the half gear 53 starts to rotate, the teeth on the half gear 53 push the teeth on the toothed plate 54 meshing with it, thereby driving the toothed plate 54 to perform translational motion toward the bottom of the electrolytic tower 1. When the half gear 53 contacts the toothed plate 54 on the other side, the teeth on the half gear 53 push the teeth on the toothed plate 54 meshing with it. The teeth enable the tooth plate 54 to translate toward the top of the electrolytic tower 1, and a support plate is installed on one side wall of an adjacent tooth plate 54, and a groove adapted to the tooth plate 54 is opened on the support plate. The groove of the support plate provides a translation trajectory for the adjacent tooth plate 54, ensuring that the adjacent tooth plates 54 can translate stably. A spring 55 is installed at one end of the adjacent tooth plate 54 close to the water retaining plate 3, and an end of the adjacent spring 55 away from the tooth plate 54 is connected to a limiting plate 56, and the limiting plate 56 is fixedly installed in the electrolytic tower 1. The limiting plate 56 limits the spring 55 so that the spring 55 has a rebound force.
[0030] First, the spring 55 on the upper side of the toothed plate 54 which is in meshing state with the half gear 53 will drive the toothed plate 54 to translate toward the top of the electrolytic tower 1 due to the elastic force after the half gear 53 and the toothed plate 54 finish meshing, while the spring 55 on the other side is in a compressed state during the upward translation of the toothed plate 54. When the half gear 53 and the toothed plate 54 finish meshing, the spring 55 will drive the toothed plate 54 to translate downward, that is, the adjacent toothed plates 54 perform reciprocating motion, and the impact ball also follows the reciprocating motion of the toothed plate 54 to impact the bottom of the electrolytic tower 1, causing the bottom of the electrolytic tower 1 to vibrate, thereby shaking off the flocculent precipitate, which slides down the arc-shaped surface to the lowest point and is discharged through the electric exhaust valve.
[0031] The degradation component 4 includes a bracket 41 fixedly mounted on the upper side of the water retaining plate 3, and a reduction motor 42 is fixedly mounted on the upper side of the bracket 41. The bracket 41 fixes the reduction motor 42 to ensure that the reduction motor 42 remains stable during operation. During the electrolytic dephosphorization process, a specific rotation speed may be required to ensure the efficiency and stability of the electrochemical reaction, and the reduction motor 42 can provide stable and appropriate power output by reducing the rotation speed. The output shaft of the reduction motor 42 is fixedly connected to a first connecting shaft 43, and the first connecting shaft 43 extends into the inner cavity of the electrolytic tower 1. When the reduction motor 42 is started, the reduction motor 42 drives the first connecting shaft 43 to rotate. The first connecting shaft 43 is movably connected with circular plates 44 with equal spacing. The circular plates 44 serve as electrodes of the electrolytic dephosphorization device. When a DC power supply is turned on, the anode is electrolyzed under the action of the power supply to produce iron ions or aluminum ions. These ions can react with phosphate ions in sewage to produce insoluble compounds, thereby achieving the purpose of phosphorus removal. The first connecting shaft 43 extends to the outer wall of the inner cavity of the electrolytic tower 1 and is fixedly installed with equally spaced stirring paddles 45. The first connecting shaft 43 drives the stirring paddles 45 to rotate, and the equally spaced stirring paddles 45 are arranged between equally spaced circular pole plates 44. The stirring paddles 45 provide the necessary stirring force to ensure uniform mixing of materials in the treatment process, which is crucial to ensuring the effective removal of phosphorus because it can promote the uniform progress of chemical reactions.
[0032] Electrode plates 6 with equal spacing are installed on the lower side of the degradation component 4 and in the inner cavity of the electrolytic tower 1, and connecting plates are installed between the electrode plates 6 with equal spacing. The electrode plates 6 are made of a new type of metal composite material, which contains electrochemically active substances and additives. The electrochemically active substances are iron oxides or hydroxides. The electrode composite material has good thermal stability and good electrochemical properties, strong reaction activity, is not easy to wear, and has low replacement costs.
[0033] A fan 7 is installed on the upper side of the water retaining plate 3. The fan 7 sucks air. An L-shaped aeration pipe is installed at the air outlet of the fan 7. The L-shaped aeration pipe pours the sucked air into the electrolytic tower 1, and the horizontal part of the L-shaped aeration pipe is provided with equally spaced air outlets. The air sucked by the fan 7 is discharged through the air outlets, and the horizontal part of the L-shaped aeration pipe is located on the lower side of the equally spaced electrode plates 6. The L-shaped aeration pipe increases the oxygen concentration in the water by injecting gas into the water, which is not only beneficial to the growth of microorganisms in the water, but also promotes their decomposition of pollutants.
[0034] A first conductive column 8 is installed on the upper side of the water retaining plate 3, and a wire is connected between the high-frequency pulse automatic reversing power supply 2 and the first conductive column 8. The high-frequency pulse automatic reversing power supply 2 energizes the first conductive column 8, and a second conductive column 9 is fixedly inserted between the equally spaced circular plates 44. An L-shaped support plate is installed at one end of the first conductive column 8 close to the oscillation component 5. The vertical part of the L-shaped support plate is connected to the equally spaced circular plates 44. The first conductive column 8 is connected to the second conductive column 9 through the L-shaped support plate to transmit current and generate an electrolytic reaction. The horizontal part of the L-shaped support plate is connected to the equally spaced electrode plates 6. The first conductive column 8 transmits current to the equally spaced electrode plates 6, so that the equally spaced electrode plates 6 are electrically connected. The electrode plates 6 with a certain spacing between them undergo an electrolytic reaction. At the same time, the device uses aluminum, iron and other metals as anodes. Under the action of direct current, the anodes are dissolved to produce Al, Fe and other ions, which develop into various hydroxyl complexes, polynuclear hydroxyl complexes and even hydroxides after a series of hydrolysis, polymerization and ferrous oxidation processes, so that the colloidal impurities and suspended impurities in the wastewater are condensed and precipitated and separated. At the same time, the charged pollutant particles migrate in the electric field, and part of their charges are neutralized by the electrodes to promote their destabilization and precipitation. When the wastewater is subjected to electrolytic flocculation treatment, it not only has a condensation and precipitation effect on the colloidal impurities and suspended impurities, but also can remove a variety of pollutants in the water due to the oxidation effect of the anode and the reduction effect of the cathode.
[0035] The opposite side walls of the electrolytic tower 1 are provided with a water inlet and a water outlet. The water inlet extends to the inner cavity of the electrolytic tower 1, and the part of the water inlet extending to the inner cavity of the electrolytic tower 1 is connected with an equidistant PE hose. Wastewater flows into the PE hose through the water inlet, and a water distribution cap is installed at one end of the equidistant PE hose away from the water inlet. The wastewater flows into the water distribution cap through the PE hose and is sprayed through the water distribution cap. The spraying method can promote full contact between water and gas, thereby strengthening oxidation. In the process of electrolytic dephosphorization, oxidation can decompose organic matter and impurities in wastewater into smaller molecules, which is beneficial to the subsequent dephosphorization process.
[0036] When the novel electrolytic dephosphorization device of the present embodiment is used, the driving motor 51 is provided to drive the half gear 53 to rotate, so that the adjacent tooth plates 54 are translated in opposite directions. After the half gear 53 passes through the tooth part, the adjacent tooth plates 54 are translated in opposite directions under the elasticity of the spring 55. In this way, the impact ball installed under the tooth plate 54 impacts the bottom of the electrolytic tower 1 to form an oscillation, and the flocculent sediment at the bottom of the tower is shaken off and discharged through the drain valve. At the same time, the degradation component 4 is used to degrade COD and the colloidal particles and various impurity particles in the water can achieve very good adsorption and flocculation effects, so that the tiny particles in the water are aggregated into larger flocs. The formed flocs are larger and denser than the flocs formed by adding flocculants, which are conducive to sedimentation, interception and separation from the water. In addition, the electrochemical technology utilizes the strong electric field between the plates and the oxidation of the strong oxidizing groups generated by the reaction to remove and kill bacteria and viruses in the water. The removal rate can reach more than 80%, thereby enhancing practicality.
