Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a multi-layer activated carbon adsorption and activated carbon regeneration integrated treatment device. Background Technology

[0002] In the field of wastewater treatment, activated carbon is widely used as a highly efficient adsorbent due to its well-developed pore structure, large specific surface area, and excellent adsorption performance. Activated carbon can effectively adsorb organic pollutants, heavy metal ions, pigments, etc., in water, thereby improving water quality. However, the adsorption capacity of activated carbon is limited. When adsorption reaches saturation, its adsorption performance will decrease significantly. Therefore, saturated activated carbon needs to be regenerated to restore its adsorption capacity.

[0003] In the field of activated carbon regeneration, various technologies such as thermal regeneration, ultrasonic regeneration, chemical regeneration, and photocatalytic regeneration are widely used. Thermal regeneration usually involves exposing activated carbon to high temperatures to cause the adsorbed pollutants to volatilize or decompose. Ultrasonic regeneration uses the energy of high-frequency sound waves to cause the adsorbates on the surface of activated carbon to be subjected to strong mechanical forces and detach. Chemical regeneration uses chemical reagents such as acids, alkalis, and salts to react with the adsorbates on activated carbon, causing them to detach from the activated carbon.

[0004] Among them, thermal regeneration technology has high energy consumption and is prone to damaging activated carbon; ultrasonic regeneration has low efficiency and limited application range; chemical regeneration has limited effect and may cause equipment corrosion and pore blockage, and the residual chemical agents are difficult to treat and are not environmentally friendly; photocatalytic regeneration technology is difficult to apply on a large scale.

[0005] Existing equipment suffers from complex operation, low efficiency, and the inability to recycle wastewater or simultaneously regenerate activated carbon. Therefore, there is a need for an integrated activated carbon adsorption and regeneration device that is easy to operate, continuous, and environmentally friendly. Utility Model Content

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] like Figure 1As shown, the multi-layer structure activated carbon adsorption and activated carbon regeneration integrated treatment device of this utility model includes an electrolytic cell 100, a DC power supply 200, and a circulation pipeline 300. The electrolytic cell 100 has multiple sets of parallel electrode plates inside, each set of electrode plates including a titanium-based lead dioxide anode plate 103 and an activated carbon granule cathode plate 104. The DC power supply 200 is connected to the multiple sets of electrode plates through wires. The negative terminal of the DC power supply 200 is connected to the activated carbon granule cathode plate 104, and the positive terminal of the DC power supply 200 is connected to the titanium-based lead dioxide anode plate 103. The circulation pipeline 300 has a centrifugal pump 303. The inlet and outlet of the circulation pipeline 300 are respectively connected to the inlet 301 and outlet 302 of the tank body. The circulation pipeline 300 is used to circulate wastewater through the tank body.

[0029] Understandably, the electrolytic cell 100 is made of corrosion-resistant materials. The titanium-based lead dioxide anode plate 103 uses a titanium substrate with a lead dioxide coating, exhibiting good conductivity and corrosion resistance. During electrolysis, it generates oxygen, oxidizing organic pollutants. The activated carbon granular cathode plate 104 is made of high-specific-surface-area activated carbon granules, possessing excellent adsorption performance and effectively adsorbing organic pollutants in the water. The DC power supply 200 provides DC current to the electrode plates, causing an electrolytic reaction on the electrode surface. Gas is generated at the anode, and organic pollutants are adsorbed at the cathode, driving the electrolytic reaction. The DC power supply 200 uses an adjustable voltage DC power supply to control the rate of the electrolytic reaction. By adjusting the output voltage and current of the DC power supply, the intensity of the electrolytic reaction can be controlled, thereby achieving the treatment of wastewater of different types and concentrations. As electrolysis proceeds, the organic pollutants on the activated carbon granular cathode plate gradually become saturated. The circulation pipeline 300 is used to transport the water to be treated and the circulating electrolyte. The inlet and outlet of the circulation pipeline 300 are connected to the inlet 301 and outlet 302 of the tank, respectively. The centrifugal pump 303 achieves continuous circulation by controlling the direction and flow rate of the water.

[0030] The working principle of wastewater treatment: After the wastewater enters the device, the pollutants are adsorbed by activated carbon particles. Control valve 401 is opened, and the wastewater enters the electrolytic cell 100 through inlet 301. Centrifugal pump 303 pumps the wastewater into the electrolytic cell, and the liquid level gradually rises. When the liquid level reaches the rated liquid level 105 of the electrolytic cell, the reaction proceeds. After the reaction is complete, control valve 401 is closed, and the reacted wastewater is discharged through outlet 302 and re-pumped back into the electrolytic cell 100 by centrifugal pump 303 to achieve circulation.

[0031] The working principle of activated carbon regeneration: When the electrolytic cell reaches a certain liquid level, the power supply is turned on, and the current, voltage, or key electrolysis parameters, such as the electrode spacing, inflow and outflow rates, stirring rate, and reaction system temperature, are controlled to achieve in-situ regeneration of the activated carbon granular filter material. During electrolysis, the applied electric field changes the adsorption equilibrium of the activated carbon, and pollutants are desorbed from the adsorption sites of the activated carbon filter electrode and oxidized and degraded by active components such as hydroxyl radicals, thereby regenerating the activated carbon electrode and realizing the reuse of the activated carbon filter electrode.

[0032] Implementation, for example Figure 1 As shown, in the multi-layer structure activated carbon adsorption and activated carbon regeneration integrated treatment device, the activated carbon granule hydraulic component directly serves as the basic unit for activated carbon adsorption. The anode uses a titanium-based lead dioxide electrode, and the cathode uses activated carbon granules. An external DC power supply 200 is connected, and the device is placed in the electrolytic cell 100. Wastewater (such as coal chemical wastewater, ecological wetland effluent, etc.) enters through the inlet 301, and the influent flow rate per unit cross-sectional area (25-127 L / (h·m³)) is controlled by a centrifugal pump 303. 2 The outlet 302 is closed. When the liquid level reaches the rated liquid level of the electrolytic cell (105), the outlet 302 is opened, the flow rates of the inlet 301 and outlet 302 are adjusted to match, and the wastewater is circulated. The adsorption time of the fixed activated carbon granules hydraulic material is 2 hours, after which adsorption is complete.

[0033] Implementation, for example Figure 1 As shown, preferably, the electrolytic cell 100 is provided with a heating device 106 and a stirring device 107. The heating device 106 is connected to the side wall of the cell body 102; the stirring device 107 is connected to the bottom surface of the cell body 102 and is located at the center of the bottom surface of the cell body 102.

[0034] Preferably, the bottom of the electrolytic cell 100 is provided with a sedimentation collection tank 108, which is located near the water outlet 302;

[0035] The outlet 302 is set at a height greater than that of the sedimentation collection tank 108.

[0036] Understandably, heating can increase the temperature of the electrolyte, thereby accelerating the rate of electrochemical reactions. Stirring can help distribute ions in the electrolyte more evenly, improving mass transfer efficiency.

[0037] Understandably, during electrolysis, the temperature of the reaction system is controlled and maintained constant by the heating device 106, and the stirring device 107 ensures a more thorough electrode regeneration process. After the activated carbon granule electrode is regenerated, the electrolysis reaction continues, resulting in efficient removal of wastewater. A sedimentation collection tank 108 is designed at the bottom of the reactor to prevent sediment from flowing out of the outlet. After the reaction is completed, the outlet 302 is opened to circulate the wastewater, ultimately completing the wastewater purification and degradation process.

[0038] During electrolysis, insoluble impurities and some reaction products in the electrolyte will gradually precipitate. Once the precipitate accumulates to a certain level in the sedimentation tank, it can be manually removed.

[0039] Optionally, the size of the sedimentation collection tank 108 can be designed according to the size of the electrolyzer 100 and the different wastewater being treated, ensuring that there is enough space to accommodate the sediment.

[0040] Preferably, the electrolytic cell 100 includes a cover 101 and a cell body 102.

[0041] Understandably, the cover 101 and the tank 102 are made of corrosion-resistant materials. The tank 102 has multiple sets of parallel and staggered electrode plates inside to increase the electrode surface area, thereby improving the electrolysis efficiency when wastewater passes through.

[0042] Preferably, the inner wall of the tank 102 is provided with a scale line for the rated liquid level 105 of the electrolytic cell.

[0043] During operation, wastewater is pumped into the electrolytic cell 100 by the centrifugal pump 303, causing the liquid level to rise. When the liquid level reaches the rated liquid level 105 of the electrolytic cell, the outlet 302 is opened, and the flow rates of the inlet 301 and the outlet 302 are adjusted by the centrifugal pump 303 to achieve wastewater circulation.

[0044] Preferably, a gas emission device 109 is provided above the electrolytic cell 100, and the gas emission device 109 is connected to the cover 101 of the electrolytic cell 100 through a gas pipe.

[0045] Understandably, the gaseous components generated during electrolysis are collected by the gas emission device 109. Its function is to safely discharge the gas generated during electrolysis outside the device, preventing gas accumulation inside the electrolytic cell and potential safety hazards. The gas emission device 109 is made of corrosion-resistant material and can withstand the corrosion caused by the gas generated during electrolysis. Optionally, if the gas generated during electrolysis contains harmful substances, a filter device can be installed in the gas emission device to purify the gas.

[0046] Preferably, the distance between the titanium-based lead dioxide anode plate 103 and the activated carbon granular cathode plate 104 is 0.5-10 cm.

[0047] Understandably, a suitable electrode spacing ensures that ions in the electrolyte can migrate rapidly to the electrode surface, thereby increasing the electrolysis reaction rate. Too small an electrode spacing can easily lead to short circuits and increase energy loss; too large an electrode spacing increases resistance and energy consumption. Optimizing the electrode spacing can reduce energy consumption. After connecting to a DC power supply 200, the wastewater undergoes deep oxidation-reduction treatment. Adjusting the electrode spacing and the heating device 106 maintains a constant wastewater temperature in the electrolytic cell to achieve better treatment results. In the electrochemical reaction process, oxidation occurs at the anode and reduction occurs at the cathode. The electrode reactions can generate a large number of oxidizing free radicals (hydroxyl radicals ·OH, hypochlorous acid radicals ClO·, etc.) or promote the migration of ions / charged pollutants or generate microbubbles, thus degrading pollutants in the wastewater.

[0048] Based on the above embodiments, after the activated carbon granular hydraulic material is saturated with adsorption, it undergoes in-situ electrochemical regeneration. An external power supply is connected to start the power supply, and the temperature of the wastewater in the electrolytic cell is controlled by adjusting the heating device 106 (20-40℃). The electrode spacing is set to 1 cm, the current range is set to 0.1-1.5 A, the flow rate is 10 mL / min, and the regeneration time is extended to 6 hours. When the current is 1 A, the regeneration time is 3 hours, and the regeneration rate of activated carbon reaches 65%. When extended to 6 hours, the regeneration rate of activated carbon is basically maintained at around 80%. Under the presence of an external electric field, the original adsorption equilibrium of the activated carbon granular hydraulic material is disrupted, and pollutants are detached from the micropores of the activated carbon, completing the activated carbon adsorption and in-situ regeneration. The electrode time is 1 hour, realizing the regeneration of the activated carbon granular hydraulic material and the oxidation degradation or reduction of pollutants.

[0049] Preferably, the titanium-based lead dioxide anode plate 103 and the activated carbon particle cathode plate 104 are flat plate structures with rectangular outer contours.

[0050] Understandably, the titanium-based lead dioxide anode plate 103 uses a titanium plate as the substrate, and a lead dioxide coating is deposited on the titanium plate through electroplating or coating methods. The activated carbon granular cathode plate 104 uses high-purity activated carbon powder, which is prepared into a rectangular plate shape by pressing. The rectangular plate electrode can provide a larger effective reaction area and improve electrolysis efficiency.

[0051] Preferably, the titanium-based lead dioxide anode plate 103 and the activated carbon particle cathode plate 104 are fixed in the tank 102 by insulating clamps.

[0052] Understandably, the insulating clamp can effectively isolate the conductivity between the electrode and the tank 102, prevent short circuits, and ensure the safe operation of the equipment.

[0053] Optionally, the fixture design should take into account the structure of the tank to ensure that the fixture can be firmly fixed inside the tank. The fixture design should facilitate installation and disassembly, and make it convenient for electrode replacement and cleaning.

[0054] Preferably, the end of the circulation pipeline 300 connected to the centrifugal pump 303 is equipped with a control valve 401 and a wastewater collector 400 for collecting and circulating wastewater.

[0055] Understandably, the wastewater collector 400 is made of corrosion-resistant material and uses a pump to transport wastewater to the electrolytic cell. A control valve 401 is installed between the wastewater collector and the centrifugal pump. The control valve 401 controls the collection of wastewater from the electrolytic cell, regulates the wastewater flow rate, and facilitates system cleaning and maintenance.

[0056] This utility model discloses a multi-layer structure activated carbon adsorption and activated carbon regeneration integrated treatment device, which also has the advantage of treating chromium wastewater, enabling chromium... 3+ Converted to Cr 6+ This enables the resource-based regeneration of chromium-containing waste acid.

[0057] To address the high-concentration chromium-containing waste acid generated during the "chromium process" expanded graphite production, this invention employs a multi-layer electrode structure design, which can transfer chromium to the anode. 3+ Conversion to oxidation to Cr 6+ It is then reused in the production process, thus achieving the resource-based regeneration of chromium-containing waste acid. Test conditions: Current 300-400A; Acidity: 14%, a strong acid environment; Flow rate: 1m³ / h. 3 / h; Processing capacity: 600L; Electrode consists of multiple sets of plates with an electrode spacing of 0.5cm. The initial Cr(VI) concentration is 60mg / L, and the Cr(VI) concentration in the effluent after electrolysis reaches 240mg / L. The overall system temperature is maintained at 32℃, and the voltage is 3.42V. This method requires no external reagents and is highly efficient, avoiding large-scale discharge of waste acid and reducing the amount of raw materials added. The generated Cr... 6+ It can be reused in the production process, realizing the recycling of resources.

[0058] In summary, this invention presents a multi-layered activated carbon adsorption and regeneration integrated treatment device. This device effectively removes organic pollutants by employing multiple sets of parallel and staggered electrode plates: a combination of titanium-based lead dioxide anode plates and activated carbon granular cathode plates, along with a circulation pipeline design. Simultaneously, auxiliary devices such as heating, stirring, and sedimentation collection further improve the device's treatment efficiency and stability. This device achieves deep wastewater treatment through a combination of physical adsorption and electrochemical oxidation. Activated carbon adsorbs organic pollutants, while the electrochemical reaction degrades the adsorbed pollutants on the activated carbon, thereby achieving activated carbon regeneration and wastewater purification.

[0059] The working principle of the multi-layer activated carbon adsorption and activated carbon regeneration integrated treatment device described in this utility model is as follows:

[0060] Wastewater from the wastewater collector enters the electrolytic cell via a centrifugal pump, where pollutants are adsorbed by activated carbon granular electrodes. Subsequently, an electrochemical reaction is initiated by applying an external direct current. During this process, the titanium-based lead dioxide anode oxidizes and degrades the organic pollutants adsorbed on the activated carbon; the activated carbon granules, acting as the cathode, adsorb even more organic pollutants. As the reaction proceeds, the activated carbon gradually becomes saturated. This process simultaneously includes desorption and oxidative degradation. As pollutants continue to degrade, the concentration difference between the activated carbon and the electrolyte further promotes the outward diffusion and desorption of pollutants until the activated carbon is completely regenerated. To achieve activated carbon regeneration, the device is equipped with a circulation pipeline. Water flow is regulated by control valves to circulate the treated wastewater back to the electrolytic cell and continuously introduce new wastewater. During electrolysis, the organic pollutants adsorbed on the activated carbon are oxidized and decomposed under the influence of the electric field, thereby restoring the activated carbon's adsorption capacity. To improve treatment efficiency, the device is also equipped with a heating device and a stirring device. The heating device increases the electrolyte temperature, accelerating the reaction rate. The stirring device ensures uniform ion distribution in the electrolyte, improving mass transfer efficiency. The precipitate produced during electrolysis flows into a sedimentation collection tank. The gas produced during electrolysis is discharged through a gas emission device.

[0061] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
