Description

Technical Field

[0001] This invention relates to the field of water treatment, and more specifically, to an activated carbon verification device and method. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Some traditional wastewater treatment methods require the use of hazardous chemicals, which are not only expensive but also environmentally damaging. Major wastewater treatment methods include adsorption of toxic elements, distillation, reverse osmosis, and membrane filtration; however, these methods all have limitations, such as membrane deformation, high operating costs, difficulties in instrument handling, formation of harmful sludge, and other treatment problems.

[0003] Activated carbon is a carbon material with a highly porous structure, possessing both physical and chemical adsorption properties, and is commonly used as an adsorbent. Because activated carbon easily reaches saturation, reducing or losing its adsorption capacity, current solutions mainly include replacing the activated carbon adsorbent with new one or regenerating saturated activated carbon. However, producing 1 ton of high-quality activated carbon requires approximately 8 tons of wood or 8 tons of raw coal, with a carbon yield of about 12.5%. This process releases large amounts of CO2, CO, sulfides, and other gaseous pollutants into the atmosphere. Therefore, new activated carbon is generally expensive, and replacing it with new carbon significantly increases production costs. Thus, desorption and regeneration of saturated activated carbon must be considered to reduce operating costs, achieve recycling, reduce waste of coal and wood resources, reduce greenhouse gas emissions, and decrease the consumption of non-renewable energy. Activated carbon regeneration refers to the process where activated carbon, after a certain period of adsorption, becomes saturated due to the adsorbate clogging its pores and reducing or completely eliminating its adsorption capacity. Regeneration desorbs and releases the adsorbate from the saturated carbon, restoring its original adsorption properties and yielding recyclable activated carbon. Currently, thermal regeneration is the most widely used and mature technology, but it suffers from drawbacks such as high energy consumption, low energy efficiency, inability to recycle the heat energy generated during regeneration, large exhaust emissions, and a high carbon loss rate.

[0004] Therefore, for wastewater treatment plants, both replacing activated carbon adsorbents and regenerating saturated activated carbon adsorbents constitute a significant portion of production costs. Thus, how to extend the service life of activated carbon adsorbents by optimizing the operating parameters of activated carbon adsorption devices is a worthwhile research topic. Furthermore, there is currently no efficient method or device for determining appropriate activated carbon and operating parameters for different wastewater types and application sites. Therefore, there is an urgent need for a verification device capable of determining activated carbon selection and operating parameters for different types of wastewater treatment.

[0036] The present invention will now be described in detail with reference to the accompanying drawings, illustrating exemplary embodiments according to the inventive concept. However, the invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. These embodiments are provided so that the disclosure of the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] Figure 1 This is a schematic block diagram of an activated carbon verification apparatus according to exemplary embodiments of the present disclosure. Figure 2 This is a simplified structural diagram of an activated carbon verification apparatus according to an exemplary embodiment of the present disclosure. Below, it will be combined with... Figure 1 and Figure 2 The activated carbon verification device of the present invention will be described in detail below.

[0038] Reference Figure 1 and Figure 2 The activated carbon validation apparatus disclosed herein includes a water supply system 100, a performance reaction validation system 200, a backwash system 300, and a controller 400, as well as optional dosing system 500, backwash discharge system 600, and a mobile platform 700. That is, the activated carbon validation apparatus of this disclosure may include only the water supply system 100, performance reaction validation system 200, backwash system 300, and controller 400, or it may further include the dosing system 500, backwash discharge system 600, and mobile platform 700.

[0039] The water supply system 100 can receive water to be treated. For example, wastewater from the secondary sedimentation tank of a wastewater treatment plant can be supplied to the water supply system 100.

[0040] The performance reaction verification system 200 is fluidly connected to the water supply system 100 and can treat the water to be treated from the water supply system 100 to obtain treated water and obtain treatment results. The performance reaction verification system 200 may include one or more (e.g., at least two) performance reaction verification units, each of which is provided with activated carbon (e.g., granular activated carbon).

[0041] In other words, the water supply system 100 can transport water to be treated to the performance reaction verification unit of the performance reaction verification system 200 via pipelines. Pollutants in the water can be adsorbed by the activated carbon in the performance reaction verification unit, and then the performance reaction verification unit discharges the treated water into a clear water tank. Water quality indicators can be obtained by sampling and testing the treated water, primarily referring to the content of pollutants in the treated water, such as COD value. For the performance reaction verification system 200, the duration for which the discharged treated water meets the required water quality indicators (e.g., COD value is lower than a predetermined value) can be defined as the treatment cycle. That is, within the treatment cycle, the performance reaction verification system 200 can discharge treated water with the required water quality indicators. When it is detected (e.g., detected several times consecutively within a predetermined time period) that the water quality indicators of the treated water discharged by the performance reaction verification system 200 do not meet the requirements, it indicates that the activated carbon in the performance reaction verification system 200 has become saturated, and the treatment cycle of the performance reaction verification system 200 ends.

[0042] The backwashing system 300 is fluidly connected to the performance reaction verification system 200 and can perform backwashing on the performance reaction verification system 200 according to different backwashing parameters. Backwashing parameters include, but are not limited to, backwashing intensity, backwashing time, and backwashing cycle. Here, backwashing intensity represents the fluid pressure during the backwashing operation, backwashing time represents the duration of each backwashing operation, and backwashing cycle represents the approximate interval between two adjacent backwashing operations. Backwashing refers to the operation of cleaning the performance reaction verification unit using the reverse flow of fluid (water or air). As the performance reaction verification system 200 is used, the activated carbon adsorbs more and more pollutants, reducing the adsorption capacity of the activated carbon and increasing the pressure inside the reactor filled with activated carbon in the performance reaction verification unit, posing a safety hazard. At this time, backwashing can wash away the pollutants adsorbed by the activated carbon, reduce the pressure inside the reactor, and extend the service life of the activated carbon to a certain extent.

[0043] Backwashing can be performed according to a set backwashing cycle, or when the pressure inside the reactor exceeds a predetermined value. Since backwashing can extend the service life of activated carbon to some extent, it is meaningful to extend the treatment cycle of the performance reaction verification system 200 by setting reasonable backwashing parameters. The activated carbon verification device of this disclosure can verify the basic properties of activated carbon (such as mesh size, iodine value, methylene blue adsorption, ash content, particle strength, pore volume, pore size distribution, specific surface area, and functional group distribution on the carbon surface) and obtain the operating parameters of the activated carbon based on the treatment results and backwashing parameters. That is, in the exemplary embodiments of this disclosure, by adjusting backwashing parameters such as backwashing intensity, backwashing time, and backwashing cycle, and measuring the water quality indicators and treatment cycles of the treated water obtained using different combinations of backwashing parameters, a better combination of backwashing parameters and the operating parameters of the activated carbon can be obtained.

[0044] The controller 400 can control the overall operation of the activated carbon verification device. For example, the controller 400 can control various operations of the water supply system 100, performance reaction verification system 200, backwash system 300 described above, and the dosing system and backwash discharge system 600 described below. However, exemplary embodiments are not limited thereto, and the controller 400 may only control the operation of some of the aforementioned devices. The controller 400 can be implemented using various operating devices and methods in the art, and is not limited to combinations of software and hardware used to implement the various functions described herein.

[0045] The dosing system 500 can provide pH-adjusting agents to the water supply system 100. For example, when the pH of the water to be treated received by the water supply system 100 is detected to be fluctuating significantly, the dosing system 500 can provide pH-adjusting agents to the water supply system 100.

[0046] The backwash discharge system 600 is fluidly connected to the performance reaction verification system 200. The performance reaction verification system 200 discharges the effluent after the backwash operation through the backwash discharge system 600.

[0047] The movable platform 700 is used to house the water supply system 100, performance reaction verification system 200, backwash system 300, controller 400, chemical dosing system 500, and backwash discharge system 600. That is, the water supply system 100, performance reaction verification system 200, backwash system 300, controller 400, chemical dosing system 500, and backwash discharge system 600 are mounted on the movable platform 700. Optionally, the controller 400 may not be mounted on the movable platform 700, but may be mounted separately. The movable platform 700 may include movable components (e.g., tires) to flexibly move the entire activated carbon verification device to different test sites.

[0048] In an exemplary embodiment of this disclosure, the backwash system 300 may include a water backwash system 310 and an aeration backwash system 320. The water backwash system 310 can perform water flushing on the performance reaction verification system 200; for example, the water backwash system 310 can supply treated water from a clean water tank to the performance reaction verification system 200 to perform water flushing on the performance reaction verification system. The aeration backwash system 320 can perform air flushing on the performance reaction verification system 200.

[0049] In an exemplary embodiment of this disclosure, each performance reaction verification unit includes a reactor and a pressure gauge. Activated carbon is disposed in the reactor. The pressure gauge can measure the pressure inside the reactor. The reactor is configured to have a cleaning cycle, and when the reactor's usage time reaches the cleaning cycle or the pressure inside the reactor reaches a predetermined value, the backwashing system 300 performs water flushing and / or air flushing on the performance reaction verification system.

[0050] Figure 3 This is a flowchart of an activated carbon verification method according to exemplary embodiments of the present disclosure. Reference will be made below. Figure 3 This describes the activated carbon verification method according to the present disclosure.

[0051] Reference Figure 3 The activated carbon verification method according to the exemplary embodiments of the present disclosure can be executed by the activated carbon verification apparatus including the water supply system 100, the performance reaction verification system 200, the backwashing system 300 and the controller 400, and the method is implemented by the controller 400.

[0052] According to an exemplary embodiment, the activated carbon verification method may include the following steps: receiving water to be treated through a water supply system (S100); supplying the water to be treated to a performance reaction verification system fluidly connected to the water supply system, treating the water to be treated to obtain treated water and obtaining a treatment result (S200), wherein the performance reaction verification system includes multiple performance reaction verification units connected in parallel with each other, and each performance reaction verification unit is provided with activated carbon; performing backwashing on the performance reaction verification system through a backwashing system according to different backwashing parameters (S300); and verifying the basic properties of the activated carbon and obtaining the operating parameters of the activated carbon based on the treatment result and the backwashing parameters (S400).

[0053] During the operation of the activated carbon verification device disclosed herein, the backwash system 300 performs a backwash operation on the performance reaction verification system 200 whenever the pressure inside the reactor exceeds a predetermined value or reaches a set backwash cycle. By adjusting backwash parameters such as backwash intensity, backwash time, and backwash cycle, the water quality indicators of the treated water and the treatment cycle of the performance reaction verification system 200 are measured under different combinations of backwash parameters. By comparison, an optimal combination of backwash parameters can be obtained. Using this combination of backwash parameters can extend the treatment cycle of the performance reaction verification system 200 while ensuring that the water quality indicators of the treated water meet the requirements.

[0054] Since the performance reaction verification system 200 includes multiple performance reaction verification units set in parallel, it can verify multiple different combinations of backwashing parameters at the same time, which facilitates the comparison of treatment results under different backwashing parameters and can quickly determine the basic properties of activated carbon and the operating parameters it is suitable for.

[0055] Furthermore, the operating parameters of the activated carbon verification device disclosed herein can be correlated with the actual operating parameters of a water plant through the mathematical model of this invention. For example, operating parameters such as the flow velocity v of the filter bed in the reaction system, the packing density ρ, the backwash time t, the water flow area A, the filter bed thickness h, and the backwash intensity (or backwash pressure) F are selected; their functional expression is as follows:

[0056] F(v, ρ, t, A, h, F)=0 (Formula 1)

[0057] The above formula contains six physical quantities: v, ρ, t, A, h, and F, with corresponding dimensions [v] = [F]. 0 L 1 T -1 ]、[ρ]=[F 1 L -4 T 2 ]、[t]=[F 0 L 0 T 1 ]、[A]=[F 0 L 2 T 0 ]、[h]=[F 0 L 1 T 0 ]、[F]=[F 1 L 0 T 0 The total number of physical quantities is n = 6, where v, ρ, and t are fundamental quantities with dimensions k = 3. Therefore, the number of independent π quantities is nk = 3. According to the π theorem of similarity theory, we obtain:

[0058]

[0059] That is, Formula 1 can be rewritten as:

[0060]

[0061] According to the positive theorem of similarity theory, the above equation can be used to obtain the various similarity indices and their expressions:

[0062]

[0063] For water plants that are not yet under construction, those that have already been built, or those that have replaced activated carbon, it is necessary to optimize their operating parameters using activated carbon verification devices. Since there are certain differences between pilot-scale or intermediate-scale experiments and the actual treatment and operation of a water plant, the operating parameters of the actual water plant cannot be directly used as the operating parameters for pilot-scale or intermediate-scale experiments. Therefore, in order to make the data results from pilot-scale or intermediate-scale experiments more closely reflect the actual operating effects of the water plant, it is necessary to establish a corresponding relationship between the two. This can be achieved by using the dimensional analysis method based on the aforementioned similarity theorem to establish a similarity index C. A C h C F C v C t C ρ The relationship between them, and can be determined by C v C t C ρ The value of the similarity index is used to determine C. A C h C F The similarity value allows for better selection of operating parameters for the activated carbon experimental verification device. Here, the similarity index refers to the proportional relationship between the model value and the prototype value (e.g., the ratio between the operating parameters of an actual wastewater treatment plant and the corresponding experimental parameters of the activated carbon verification device).

[0064] In the following text, reference will be made to Figure 4 The specific construction of a portion of the activated carbon verification apparatus according to exemplary embodiments of the present disclosure is described.
