Description

Technical Field

[0001] This utility model relates to the field of wastewater degradation, and in particular to an electrocatalytic degradation device for dyeing and printing wastewater. Background Technology

[0002] Wastewater degradation is a key process in treating wastewater and reducing its pollutant concentration. It is mainly achieved through physical, chemical, and biological methods. Physical methods, such as gravity separation, centrifugal separation, and filtration, are mainly used to remove suspended solids, oils, and other substances from wastewater. Chemical methods utilize chemical reactions, such as oxidation, precipitation, and coagulation, to decompose or remove organic and inorganic impurities from wastewater. Biological treatment utilizes the metabolic activity of microorganisms to convert organic matter into inorganic matter, and is a commonly used method for removing organic matter. It includes two types: aerobic and anaerobic treatment. Aerobic treatment uses oxygen to promote microbial metabolism and is suitable for low-concentration wastewater. Anaerobic treatment is carried out under anaerobic conditions and is suitable for high-concentration organic wastewater. In practical applications, it is often necessary to use a combination of methods to achieve the best wastewater treatment effect and ensure that the wastewater meets environmental standards and requirements before discharge, thereby protecting the environment and human health.

[0003] Wastewater degradation requires various treatment methods, but traditional methods are energy-intensive and inefficient. To address these issues, an electrocatalytic degradation device for dyeing and printing wastewater is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electrocatalytic degradation treatment device for dyeing and printing wastewater, which aims to improve the traditional treatment methods in the prior art, which have high energy consumption and low efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrocatalytic degradation device for treating dyeing and printing wastewater includes: an plexiglass reactor, with glass partitions fixedly installed on both sides of the inner wall of the plexiglass reactor, an anode plate disposed on the left side of the glass partitions, a cathode plate disposed on the right side of the glass partitions, an outlet and an inlet disposed on the front of the plexiglass reactor, a peristaltic pump connected to the outside of the inlet, and a power source disposed on the right side of the plexiglass reactor.

[0007] The above technical solution cleverly separates the anode and cathode plates using a built-in glass partition in the plexiglass reactor, creating a stable electrochemical reaction environment. An external peristaltic pump at the inlet precisely controls the wastewater flow, ensuring a uniform and stable flow into the reactor. Simultaneously, a power source on the right side of the device provides the necessary electrical energy for the electrocatalytic reaction, promoting an oxidation-reduction reaction between the anode and cathode to effectively degrade dyeing pollutants in the wastewater. This treatment method not only removes harmful substances from the wastewater but also avoids the addition of chemical agents, reducing the risk of secondary pollution.

[0008] As a further description of the above technical solution: a support frame is provided on the left side of the plexiglass reactor, an plexiglass cover is fixedly connected to the bottom of the support frame, a positioning plate is fixedly connected to the bottom of the plexiglass cover, and an LED light is fixedly installed on the bottom of the positioning plate.

[0009] Through the above technical solution, LED lights can emit light of specific wavelengths that directly illuminate the wastewater in the reactor. This illumination not only enhances the electrocatalytic degradation effect and increases the degradation rate of harmful substances in the wastewater, but also promotes the activity of microorganisms in the reactor, further improving the efficiency of wastewater treatment. At the same time, the use of LED lights also has a certain energy-saving effect; compared with traditional light sources, they consume less energy and have a longer lifespan, thereby reducing the operating costs of wastewater treatment.

[0010] As a further description of the above technical solution: the anode plate is made of titanium, and the cathode plate is made of graphite.

[0011] Through the above technical solutions, titanium plates, as anode plates, possess excellent corrosion resistance and stability, maintaining high catalytic activity for extended periods during electrocatalytic degradation. They are not easily corroded by chemicals in wastewater, thus extending the lifespan of the device. Furthermore, titanium plates exhibit good electrical conductivity, ensuring the smooth progress of the electrocatalytic reaction. Graphite, as cathode plates, is renowned for its excellent electrical conductivity and high specific surface area. Graphite provides more electron transport channels, promoting the electrocatalytic reaction. In addition, graphite has a certain adsorption capacity, capable of adsorbing some harmful substances in wastewater, further improving wastewater treatment efficiency.

[0012] As a further description of the above technical solution: both sides of the glass partition are fixedly connected with limiting plates, which are used to position the anode plate and the cathode plate.

[0013] The above technical solution ensures that the anode plate and cathode plate are stably and accurately positioned within the reactor by setting the limiting plate. The presence of the limiting plate prevents the anode plate and cathode plate from shifting or deforming during wastewater flow or electrocatalytic reaction, thereby ensuring the uniformity and stability of the electrocatalytic reaction.

[0014] As a further description of the above technical solution: the anode plate is connected to the positive terminal of the power supply, the cathode plate is connected to the negative terminal of the power supply, and the plexiglass reactor contains activated carbon-supported titanium dioxide; or other types of catalysts are not specifically limited in this utility model.

[0015] Through the above technical solution, by introducing titanium dioxide supported on activated carbon, the electrocatalytic degradation device for dyeing and printing wastewater treatment has shown significant advantages in terms of improved adsorption performance, photocatalytic activity, conductivity, and mechanical strength. These advantages enable the device to exhibit higher efficiency, better stability, and longer service life when treating dyeing and printing wastewater.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this invention, wastewater is introduced into the interior of an organic glass reactor via a peristaltic pump. Then, power is supplied to the anode and cathode plates to ionize the wastewater. At the same time, LED lights are activated. The activated carbon-supported titanium dioxide added to the reactor acts as a catalyst, which enhances the activity of the electrocatalytic reaction and improves the efficiency of wastewater treatment. These catalysts can adsorb pollutants in the wastewater and accelerate their degradation process through electrocatalysis. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The glass partitions 2 inside the plexiglass reactor 1 cleverly separate the anode plate 3 and the cathode plate 4, forming a stable electrochemical reaction environment. The peristaltic pump 7 connected to the inlet 6 can precisely control the flow rate of wastewater, ensuring that the wastewater enters the reactor evenly and stably. At the same time, the power supply 8 on the right side of the device provides the necessary electrical energy for the electrocatalytic reaction, promoting the oxidation-reduction reaction between the anode and cathode, effectively degrading the dyeing and printing pollutants in the wastewater. This treatment method not only removes harmful substances from the wastewater but also avoids the addition of chemical agents, reducing the risk of secondary pollution.

[0024] Reference Figure 1-2 A support frame 9 is installed on the left side of the plexiglass reactor 1. An plexiglass cover 10 is fixedly connected to the bottom of the support frame 9. A positioning plate 11 is fixedly connected to the bottom of the plexiglass cover 10. An LED light 12 is fixedly installed at the bottom of the positioning plate 11. The LED light 12 emits light of a specific wavelength that directly illuminates the wastewater inside the reactor. This illumination not only enhances the electrocatalytic degradation effect and increases the degradation rate of harmful substances in the wastewater, but also promotes the activity of microorganisms within the reactor, further improving the efficiency of wastewater treatment. Simultaneously, the use of the LED light 12 also has a certain energy-saving effect; compared to traditional light sources, it consumes less energy and has a longer lifespan, thereby reducing the operating costs of wastewater treatment.

[0025] Reference Figure 1-2 The anode plate 3 is made of titanium, and the cathode plate 4 is made of graphite. Limiting plates 13 are fixedly connected to both sides of the glass partition 2. The limiting plates 13 are used to position the anode plate 3 and the cathode plate 4. The anode plate 3 is connected to the positive terminal of the power supply 8, and the cathode plate 4 is connected to the negative terminal of the power supply 8. Titanium dioxide supported on activated carbon is added to the plexiglass reactor 1.

[0026] Working principle: Wastewater is introduced into the interior of the plexiglass reactor 1 via a peristaltic pump 7. Power is then supplied to the anode plate 3 and cathode plate 4 via a power source 8, thereby ionizing the wastewater. Simultaneously, LED lights 12 are activated. Titanium dioxide supported on activated carbon added to the reactor acts as a catalyst, enhancing the activity of the electrocatalytic reaction and improving the efficiency of wastewater treatment. These catalysts adsorb pollutants in the wastewater and accelerate their degradation process through electrocatalysis. LED lights 12 installed at the bottom of the plexiglass cover 10 emit light of a specific wavelength, which penetrates the plexiglass cover 10 and irradiates the wastewater inside the reactor. This light excites the photosensitive substances and catalysts in the wastewater, generating an additional photocatalytic effect. The combination of photocatalysis and electrocatalysis further improves the efficiency and quality of wastewater treatment. After electrocatalytic and photocatalytic treatment, the wastewater is discharged from the reactor outlet 5. At this point, most of the organic and inorganic substances in the wastewater have been degraded or transformed into harmless substances.
