Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a reduction-oxidation electrochemical wastewater treatment device. Background Technology

[0002] Wastewater treatment is a crucial process aimed at bringing wastewater to a level where it can be safely discharged into a specific water body or meets water quality standards for reuse. This process involves purifying wastewater to remove harmful substances and pollutants. Wastewater treatment technology is widely used in various sectors of society, including agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering. Today, with the increasing environmental awareness and technological advancements, wastewater treatment technology is increasingly becoming a part of everyday life for ordinary people and has become an indispensable part of modern society.

[0003] Chinese patent CN220317491U discloses an electrochemical wastewater treatment device. This device utilizes an electrolytic water treatment tank, a cathode rod, a movable plate, a DC regulated power supply, an electric telescopic rod, an anode rod, an annular cleaning plate, an annular scraper, and a connecting block. The annular cleaning plate drives the annular scraper to continuously scrape the outer wall of the anode rod vertically. This prevents the condensate generated on the anode rod from forming scale before it is scraped off by the annular scraper. This solves the problem of anode rod passivation during the electrochemical reaction, which increases the resistance of the anode rod and reduces the electrochemical wastewater treatment effect.

[0004] However, when this wastewater treatment device is in use, it can only remove deposits and dirt from the electrode surface, but cannot treat deposits and dirt on the inner wall of the tank. This causes the deposits on the inner wall of the tank to accumulate continuously, which in turn gradually reduces the effective volume of the treatment tank and seriously affects the efficiency of wastewater treatment. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see Figures 1 to 7 As shown, a reduction-oxidation electrochemical wastewater treatment device includes:

[0039] Wastewater treatment pond 1;

[0040] A treatment mechanism 2 is installed at the top center of the sewage treatment tank 1, an air flotation mechanism 3 is installed at the bottom center of the sewage treatment tank 1, and a detection mechanism 5 is installed on the lower part of the outer surface of the sewage treatment tank 1.

[0041] The treatment mechanism 2 includes a fixed plate 21, an anode rod 22, a cathode rod 23, a driver 24, a reciprocating screw 25, a cleaning frame 26, and a cleaning rack 27. The fixed plate 21 is installed at the top of the sewage treatment tank 1. The anode rod 22 is installed on one side of the bottom end of the fixed plate 21. The cathode rod 23 is installed on the other side of the bottom end of the fixed plate 21. The driver 24 is installed in the middle of the top of the fixed plate 21. The reciprocating screw 25 is installed in the middle of the bottom end of the fixed plate 21 through a bearing, and the bottom end of the reciprocating screw 25 is installed on the inner wall of the bottom of the sewage treatment tank 1 through a bearing. The cleaning frame 26 is installed on the outer surface of the reciprocating screw 25. There are two cleaning racks 27, and both cleaning racks 27 are installed on the lower part of the outer surface of the reciprocating screw 25.

[0042] Depend on Figures 1 to 4 It can be seen that a controller 4 is installed on the upper part of one end of the air flotation mechanism 3, a drain pipe 6 is installed on the lower part of one end of the sewage treatment tank 1, and four support feet 7 are installed around the bottom of the sewage treatment tank 1.

[0043] The cleaning frame 26 includes a movable frame 261, through holes 262, a cleaning brush 263, a cleaning wipe 264, and a connecting hole 265. Multiple through holes 262 are provided, and all through holes 262 are opened at the bottom end of the movable frame 261. The cleaning brush 263 is installed on the outer surface of the movable frame 261. Two cleaning wipes 264 are provided, and the two cleaning wipes 264 are respectively embedded on the top two sides of the movable frame 261. The connecting hole 265 is opened at the top upper part of the movable frame 261, and the movable frame 261 is installed on the outer surface of the reciprocating lead screw 25 through the connecting hole 265.

[0044] As described above, firstly, the wastewater to be treated is injected into the wastewater treatment tank 1. Then, both the anode rod 22 and the cathode rod 23 are energized, and their electrode reactions decompose the organic matter in the water, converting it into inorganic matter. This achieves oxidation-reduction electrochemical treatment of pollutants in the wastewater, thus purifying the water. Simultaneously, the controller 4 controls the start of the driver 24, which drives the reciprocating screw 25 to rotate. This action causes the moving frame 261 to drive the cleaning brush 263 and two cleaning wipes 264 to move back and forth, respectively cleaning the inner wall of the wastewater treatment tank 1 and the anode rod 22. The outer wall of the cathode rod 23 and the moving frame 261, when moving, can also stir the sewage through multiple through holes 262. The flow of sewage helps to improve the efficiency and selectivity of the electrochemical reaction. In addition, the reciprocating screw 25 drives the two cleaning frames 27 to rotate, which can clean the bottom wall of the sewage treatment tank 1. This process can simultaneously and thoroughly remove the deposits and dirt on the two electrode surfaces and the inner wall of the sewage treatment tank 1, keep the electrodes clean and efficient, effectively avoid the continuous accumulation of deposits on the inner wall of the tank, thereby preventing the gradual reduction of the effective volume of the sewage treatment tank 1, and thus improving the efficiency of sewage treatment.

[0045] Specifically, refer to Figures 1 to 4 As shown, the movable frame 261 is configured with a cross-shaped structure. The bristles on the outer surface of the cleaning brush 263 and the bristles on the outer surface of the cleaning frame 27 are in contact with the inner wall of the sewage treatment tank 1. The wiping surfaces of the two cleaning brushes 264 are in contact with the outer surfaces of the anode rod 22 and the cathode rod 23, respectively. The anode rod 22, the cathode rod 23 and the driver 24 are all electrically connected to the controller 4.

[0046] As can be seen from the above, the movable frame 261 can stably support and move the cleaning brush 263 or other cleaning tools. Through the contact of the bristles, the dirt and deposits on the inner wall of the sewage treatment tank 1 can be effectively cleaned, keeping the tank wall clean. The cleaning brush 264 can remove dirt and deposits from the outer surface of the anode rod 22 and cathode rod 23, keeping the electrodes clean and working efficiently. The controller 4 can realize precise control and adjustment of the anode rod 22, cathode rod 23 and driver 24 to meet the needs of the electrochemical treatment process.

[0047] Example 2:

[0048] refer to Figure 5 and Figure 6As shown, the air flotation mechanism 3 includes a filter box 31, an outlet pipe 32, an adjustment mechanism 33, an air pump 34, an air supply pipe 35, and a bubble diffuser 36. The outlet pipe 32 is installed at the lower part of one end of the filter box 31, the adjustment mechanism 33 is installed at the top of the filter box 31, the air pump 34 is installed at the lower part of the outer wall of the filter box 31, the air supply pipe 35 is installed on the outer wall of the air pump 34, and multiple bubble diffusers 36 are provided, and multiple bubble diffusers 36 are all installed at the top of the air supply pipe 35. The tops of multiple bubble diffusers 36 are all embedded in the bottom of the sewage treatment tank 1.

[0049] The regulating mechanism 33 includes a pump 331, a suction pipe 332, a suction head 333, an regulating plate 334, and an electric telescopic rod 335. The pump 331 is installed at the top of the filter box 31, the suction pipe 332 is installed at the top of the pump 331, and there are two suction heads 333 and two electric telescopic rods 335. The two suction heads 333 are installed at both ends of the suction pipe 332, the regulating plate 334 is installed on the upper part of the outer surface of the suction pipe 332, and the two electric telescopic rods 335 are installed on both sides of the bottom end of the regulating plate 334, and the bottom ends of the two electric telescopic rods 335 are installed at the top of the filter box 31.

[0050] As can be seen from the above, the air pump 34 is started by the controller 4 to extract air. The air is input into multiple bubble diffusers 36 through the air supply pipe 35. These gases can be evenly released into the sewage in the sewage treatment tank 1 through the tiny air holes on the bubble diffuser 36. With the rising buoyancy of the bubbles, suspended solids, colloids and other pollutants in the sewage are carried to the water surface and float. At this time, the electric telescopic rod 335 is started by the controller 4. The electric telescopic rod 335 extends and pushes the adjusting plate 334 to move upward, so that the folded part on the suction pipe 332 unfolds. At the same time, it drives the two sludge suction heads 333 on it to move to the water surface position. Then, the controller 4 controls the suction pump 331 to start to generate suction, so that the two sludge suction heads 333 extract the pollutants on the water surface and then input them into the filter box 31 through the suction pipe 332, thereby realizing solid-liquid separation.

[0051] Preferred, Reference Figure 5 and Figure 6 As shown, the material pump 331, the electric telescopic rod 335 and the air pump 34 are all electrically connected to the controller 4. The upper part of the outer surface of the material pumping pipe 332 is set with a Y-shaped structure, and a section of the material pumping pipe 332 is set with a folded structure. The top surface of the bubble diffuser 36 is flush with the bottom inner wall of the sewage treatment tank 1, and the bottom surface of the filter box 31 is flush with the bottom surface of the support foot 7.

[0052] As can be seen from the above, the controller 4 can achieve precise control and adjustment of these devices. The Y-shaped structure allows the suction pipe 332 to combine the fluids drawn by the two suction heads 333, while the folded structure of the suction pipe 332 increases the flexibility of the pipe, ensuring that the air bubbles can be evenly distributed at the bottom of the sewage treatment tank 1, improving the flotation effect, and helping to remove pollutants such as suspended solids and colloids. This allows the filter box 31 and the support feet 7 to be placed on the ground, improving the stability of the entire sewage treatment device.

[0053] Example 3:

[0054] refer to Figure 7 As shown, the detection mechanism 5 includes a mounting frame 51, a pH sensor 52, a conductivity sensor 53, and a dissolved oxygen sensor 54. The mounting frame 51 is installed on the outer surface of the sewage treatment tank 1. The pH sensor 52, conductivity sensor 53, and dissolved oxygen sensor 54 are all installed on the outer surface of the mounting frame 51, and the pH sensor 52, conductivity sensor 53, and dissolved oxygen sensor 54 are all embedded in the outer wall of the sewage treatment tank 1.

[0055] As can be seen from the above, the pH sensor 52, conductivity sensor 53, and dissolved oxygen sensor 54 can be firmly installed on the sewage treatment tank 1 through the mounting frame 51, and these sensors are all in contact with the sewage in the sewage treatment tank 1. At this time, the pH sensor 52 can monitor the acidity and alkalinity of the sewage in real time, i.e., pH value; the conductivity sensor 53 can detect the concentration of total ions in the sewage; and the dissolved oxygen sensor 54 can monitor the dissolved oxygen content in the sewage. These sensors work together to detect various water quality parameters of the sewage in real time during the treatment process and transmit the detection data to the controller 4. The controller 4 can automatically adjust the treatment parameters of the anode rod 22 and cathode rod 23 for the sewage according to the detection results to ensure that the treatment effect reaches the optimal state. Therefore, it is suitable for treating various types of sewage, adapting to different water quality changes, and ensuring stable and reliable treatment effect.

[0056] Preferred, Reference Figure 7 As shown, the mounting frame 51 is configured as a ring structure, and the pH sensor 52, conductivity sensor 53 and dissolved oxygen sensor 54 are all electrically connected to the controller 4.

[0057] As can be seen from the above, the ring-shaped mounting frame 51 is designed to conveniently fix and reasonably distribute the pH sensor 52, conductivity sensor 53 and dissolved oxygen sensor 54. Through these sensors, water quality parameters in the sewage treatment process can be monitored in real time, and the data can be transmitted to the controller 4 for precise control and regulation.

[0058] Application example:

[0059] This design is applicable to various scenarios requiring efficient and environmentally friendly wastewater treatment, including but not limited to industrial park wastewater treatment plants, chemical and pharmaceutical enterprises, electroplating and dyeing enterprises, and domestic wastewater treatment. The wastewater generated by these enterprises or sectors has a complex composition and may contain various pollutants such as heavy metals, organic matter, and ammonia nitrogen, thus requiring proper treatment. The reduction-oxidation electrochemical wastewater treatment device in this design operates primarily based on the principle of electrochemical oxidation-reduction. Through the setting of treatment mechanism 2, it utilizes the electrode reactions of anode rod 22 and cathode rod 23 to oxidize, reduce, decompose, precipitate, or adsorb pollutants in the wastewater. During the wastewater treatment process, the device can simultaneously clean the outer surfaces of anode rod 22 and cathode rod 23. The inner wall of the sewage treatment tank 1 effectively prevents the continuous accumulation of sediment, thereby enhancing sewage treatment efficiency. By setting up an air flotation mechanism 3, the buoyancy of the rising air bubbles carries suspended solids, colloids and other pollutants to the water surface. These air bubbles appear in the form of tiny bubbles, adhere to the pollutants in the raw water and float to the water surface. Then, the suspended solids on the water surface are extracted by the adjustable sludge suction head 333, realizing the rapid and efficient removal of various pollutants in sewage. In addition, by setting up a detection mechanism 5, water quality parameters (such as pH value, conductivity, dissolved oxygen, etc.) are detected in real time, and the treatment parameters (such as current, voltage, etc.) are automatically adjusted according to the detection results to ensure that the treatment effect reaches the best state, improving the accuracy and stability of the treatment.
