Description

Technical Field

[0001] This application relates to the field of waste liquid treatment technology, and in particular to a method and system for classifying, recycling, and monitoring the capacity of hazardous laboratory waste liquids. Background Technology

[0002] In modern education and research, laboratories are being used more frequently, resulting in an increase in the types and quantities of waste liquids. These waste liquids are often volatile, toxic, or corrosive, and improper handling can not only cause serious environmental pollution but also pose a threat to human health. Therefore, it is necessary to recycle waste liquids in laboratories.

[0003] To reduce the likelihood of waste liquids reacting and generating more polluting substances, and to mitigate potential hazards to the laboratory, waste liquids need to be sorted and treated during recycling. Currently, waste liquid recycling is handled by dedicated laboratory managers. While this ensures timely recycling, the diverse range of laboratory experiments and the complex composition of waste liquids place high demands on these managers' understanding of the reactions between different waste liquids, increasing recycling costs. Using conventional laboratory managers, while reducing labor costs, may result in ineffective waste liquid analysis, increasing the potential hazards associated with waste liquid recycling. Summary of the Invention

[0004] To achieve low-cost and safe recycling of waste liquids, embodiments of this application provide a method and system for classifying, recycling, and monitoring the capacity of hazardous laboratory waste liquids.

[0005] In a first aspect, this embodiment provides a method for classifying and recycling hazardous laboratory waste liquids, applied to a recycling device with multiple waste liquid recycling areas. The recycling device includes a waste liquid storage area and multiple waste liquid recycling areas. The method includes: Obtain a waste liquid recycling signal, and open the storage inlet of the waste liquid storage area to receive the waste liquid to be recycled based on the waste liquid recycling signal; Obtain the information on the waste liquid to be recycled and the information on the waste liquid already recycled in each waste liquid recycling area, and determine the target waste liquid recycling area where the waste liquid to be recycled needs to be recycled based on the information on the waste liquid to be recycled and the information on the waste liquid already recycled; Based on the target waste liquid recycling area, a corresponding target waste liquid storage signal is generated, and based on the target waste liquid storage signal, the connection channel between the waste liquid storage area and the target waste liquid recycling area is opened so as to recycle the waste liquid to be recycled in the target waste liquid recycling area.

[0006] In some embodiments, a camera is mounted on top of the waste liquid storage area, and the step of opening the storage inlet of the waste liquid storage area to receive the waste liquid to be recycled based on the waste liquid recovery signal includes: The imaging device is activated based on the waste liquid recycling signal to obtain an internal image of the waste liquid storage area. Based on the internal image, it is determined whether there is residual liquid in the waste liquid storage area. If not, the storage inlet of the waste liquid storage area is opened to receive the waste liquid to be recycled. If so, a residual liquid recovery signal is generated to recover the residual liquid, and after the residual liquid recovery is completed, the storage inlet of the waste liquid storage area is opened to receive the waste liquid to be recovered.

[0007] In some embodiments, the waste liquid storage area is funnel-shaped, and a solid detector is fixed at the bottom center of the waste liquid storage area. A liquid detector is also provided on the side wall near the bottom of the waste liquid storage area. The information to be recycled includes the volume of the waste liquid to be recycled, the substances in the waste liquid to be recycled, and the concentration or mass of each substance in the waste liquid to be recycled. Obtaining the information to be recycled includes: The liquid detector is used to obtain the liquid substance in the waste liquid to be recycled and the concentration of the liquid substance; The volume of the waste liquid to be recycled is obtained using the imaging device. The solids in the waste liquid to be recycled and the mass of the solids are obtained using a solid detector and imaging device.

[0008] In some embodiments, the recovered information includes recovered waste liquid substances, and determining the target waste liquid recycling area where the waste liquid to be recycled needs to be recycled based on the to-be-recovered information and the recovered information includes: Substitute each piece of recovered information and the information to be recovered into a preset chemical group to obtain the reaction information after each piece of recovered information reacts with the information of waste liquid to be recovered; Determine whether there are any set classification requirements for the stored data. If not, determine whether each reaction information meets the industry classification requirements and identify the target waste liquid recycling area from the waste liquid recycling areas that meet the industry classification requirements. If so, determine whether each reaction information meets the set classification requirements, and determine the target waste liquid recovery area from the waste liquid recovery areas that meet the set classification requirements.

[0009] In some of these embodiments, determining the target wastewater recycling area from wastewater recycling areas that meet industry classification requirements includes: Waste liquid recycling areas that meet industry classification requirements are identified as candidate waste liquid recycling areas. The number of candidate waste liquid recycling areas is obtained. If the number of candidate waste liquid recycling areas is zero, the emergency recycling area in the recycling device is identified as the target waste liquid recycling area. If the number of candidates is one, the candidate waste liquid recycling area is determined as the target waste liquid recycling area; If the number of candidates is greater than one, obtain the remaining capacity and the amount of substances contained in the reaction information corresponding to each candidate waste liquid recycling area, and determine the candidate waste liquid recycling area with a remaining capacity greater than the volume of the waste liquid to be recycled as the candidate waste liquid recycling area. The waste liquid recycling area with the smallest amount of substance among all the alternative waste liquid recycling areas is determined as the target waste liquid recycling area.

[0010] In some embodiments, generating a residual liquid recovery signal to recover the residual liquid includes: Based on the internal image, the type of residual liquid is determined. If the residual liquid type only contains solid residual liquid, a solid residual liquid recovery signal is generated. Based on the solid residual liquid recovery signal, the storage inlet of the waste liquid storage area is opened to retrieve the residual liquid for recycling. If the residual liquid type includes liquid residual liquid, obtain the residual liquid recycling area corresponding to the residual liquid, generate a corresponding liquid residual liquid recycling signal based on the residual liquid recycling area, and open the connection channel between the residual liquid storage area and the residual liquid recycling area based on the liquid residual liquid recycling signal, so as to recycle the residual liquid in the residual liquid recycling area. A recycling image of the waste liquid storage area is acquired, and it is determined whether the recycling image contains solid residual liquid. If so, a solid residual liquid recycling signal is generated, and the storage inlet of the waste liquid storage area is opened based on the solid residual liquid recycling signal to retrieve the residual liquid for recycling.

[0011] In some embodiments, each waste liquid recovery area corresponds to a reagent bottle recovery area, and the method further includes: When the waste liquid is recycled in the target waste liquid recycling area, the corresponding reagent bottle is also recycled in the reagent bottle recycling area corresponding to the target waste liquid recycling area.

[0012] Secondly, this embodiment provides a capacity monitoring and early warning method, which uses a laboratory hazardous waste liquid classification and recycling method as described in the first aspect to classify and recycle waste liquid in the laboratory, the method comprising: The historical waste liquid volume of each waste liquid recovery zone in the recovery device is obtained, and the waste liquid volume change curve corresponding to each waste liquid recovery zone is obtained by fitting all the historical waste liquid volumes. Obtain the total storage capacity and the stored waste liquid capacity of each waste liquid recovery zone in the recycling device; The remaining capacity of each waste liquid recovery zone is determined based on its total storage capacity and waste liquid capacity, respectively. The future volume to be recycled for each waste liquid recycling zone is predicted based on the volume change curve of the recycled waste liquid corresponding to each waste liquid recycling zone. Determine whether the future volume of waste liquid to be recycled in the same waste liquid recycling area is not greater than the remaining capacity. If not, generate an early warning signal to deal with the recycling device. If so, continue to obtain the total storage capacity and the stored waste liquid capacity of each waste liquid recovery zone in the recovery device.

[0013] Thirdly, this embodiment provides a laboratory hazardous waste liquid classification and recycling system, applied to a recycling device with multiple waste liquid recycling areas. The recycling device includes a waste liquid storage area and multiple waste liquid recycling areas. The system includes: an acquisition module, a storage module, a classification module, and a recycling module; wherein... The acquisition module is used to acquire waste liquid recovery signals; The storage module is used to open the storage inlet of the waste liquid storage area based on the waste liquid recycling signal to receive the waste liquid to be recycled. The classification module is used to obtain the information on the waste liquid to be recycled and the information on the waste liquid already recycled in each waste liquid recycling area, and to determine the target waste liquid recycling area where the waste liquid to be recycled needs to be recycled based on the information on the waste liquid to be recycled and the information on the waste liquid already recycled. The recycling module is used to generate a corresponding target waste liquid storage signal based on the target waste liquid recycling area, and open the connection channel between the waste liquid storage area and the target waste liquid recycling area based on the target waste liquid storage signal, so as to recycle the waste liquid to be recycled in the target waste liquid recycling area.

[0014] Fourthly, this embodiment provides a capacity monitoring and early warning method, which uses a laboratory hazardous waste liquid classification and recycling method as described in the first aspect to classify and recycle waste liquid in the laboratory. The system includes: a monitoring module, a processing module, and an early warning module; wherein, The monitoring module is used to obtain the historical waste liquid volume of each waste liquid recovered in each waste liquid recovery zone of the recovery device, and to obtain the total storage capacity and the stored waste liquid capacity of each waste liquid recovery zone of the recovery device. The processing module is used to fit all historical waste liquid volumes to obtain the waste liquid volume change curve corresponding to each waste liquid recycling zone, determine the remaining capacity of each waste liquid recycling zone based on the total storage capacity and waste liquid capacity of each waste liquid recycling zone, and predict the future volume to be recycled for each waste liquid recycling zone based on the waste liquid volume change curve corresponding to each waste liquid recycling zone. The early warning module is used to determine whether the future volume to be recycled in the same waste liquid recycling area is not greater than the remaining capacity. If not, an early warning signal is generated to process the recycling device; if so, the total storage capacity and the stored waste liquid capacity of each waste liquid recycling area in the recycling device are obtained.

[0015] By employing the aforementioned laboratory hazardous waste liquid classification and recycling method, this application utilizes a recycling device with multiple waste liquid recycling zones. The recycling device includes a waste liquid storage area and multiple waste liquid recycling zones. A waste liquid recycling signal is acquired, and based on this signal, the storage inlet of the waste liquid storage area is opened to receive the waste liquid to be recycled. Information regarding the waste liquid to be recycled and the already recycled information in each waste liquid recycling zone is acquired. Based on this information, a target waste liquid recycling zone is determined where the waste liquid to be recycled should be placed. A corresponding target waste liquid storage signal is generated based on the target waste liquid recycling zone, and based on this signal, the connection channel between the waste liquid storage area and the target waste liquid recycling zone is opened to collect the waste liquid to be recycled in the target waste liquid recycling zone. In this way, the recycling device automatically and safely places the waste liquid to be recycled in a waste liquid recycling zone that ensures laboratory safety, eliminating the need for laboratory management personnel and achieving low-cost and safe waste liquid recycling.

[0023] To better understand the purpose, technical solutions, and advantages of this application, it has been described and illustrated below with reference to the accompanying drawings and embodiments. However, those skilled in the art should understand that this application can be implemented without these details. It will be apparent to those skilled in the art that various modifications can be made to the embodiments disclosed in this application, and the general principles defined in this application can be applied to other embodiments and application scenarios without departing from the principles and scope of this application. Therefore, this application is not limited to the illustrated embodiments, but is consistent with the broadest scope claimed in this application.

[0024] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of a recovery device for recovering waste liquid in a laboratory, provided in an embodiment of this application. Figure 1 As shown, the recycling device includes a waste liquid storage area and multiple waste liquid recycling areas. The waste liquid storage area has a storage inlet and a storage outlet, and each waste liquid recycling area has a recycling inlet and a recycling outlet. Each storage outlet is connected to each recycling inlet via a separate connection channel. When recycling hazardous waste liquid from the laboratory, the waste liquid first enters the waste liquid storage area through the storage inlet. Then, a series of information about the waste liquid is acquired in the waste liquid storage area and sent to the processing unit. Based on this information and the information from each waste liquid recycling area, the processing unit determines which waste liquid recycling area is needed to process the waste liquid from the storage area. Finally, the recycling inlet and storage outlet of the waste liquid recycling area that needs to receive the waste liquid are opened, and the waste liquid is sorted and recycled through the connection channel. This method automatically, cost-effectively, and safely completes the sorting and recycling of waste liquid using only one set of testing equipment, eliminating the need for multiple sets of testing equipment and dedicated laboratory management personnel.

[0026] Figure 2 This is a block diagram of a laboratory hazardous waste liquid classification and recycling method provided in an embodiment of this application. The method is applied to the aforementioned recycling device with multiple waste liquid recycling zones. Figure 2 As shown, a method for classifying and recycling hazardous laboratory waste liquid includes the following steps: Step S100: Obtain the waste liquid recycling signal, and open the storage inlet of the waste liquid storage area to receive the waste liquid to be recycled based on the waste liquid recycling signal.

[0027] This embodiment is described from the perspective of the processing end. The aforementioned waste liquid recovery signal refers to the signal indicating that waste liquid classification and recovery work is required. This waste liquid recovery signal is sent by the experimenter to the processing end when there is waste liquid that needs to be recovered, so that the processing end can receive the waste liquid recovery signal.

[0028] Figure 3 This is a schematic diagram of the internal structure of the waste liquid storage area provided in an embodiment of this application. For example... Figure 3 As shown, a detection device is installed in the waste liquid storage area. This device includes an imaging unit, a liquid detector, and a solid detector. The waste liquid storage area is funnel-shaped. The imaging unit is located at the top of the waste liquid storage area, the solid detector is fixed at the center of the bottom of the waste liquid storage area, and the liquid detector is located on the side wall near the bottom of the waste liquid storage area. Capacity graduations are also engraved on the inner wall of the waste liquid storage area. By introducing a shared waste liquid storage area, only one detection device is needed to obtain the status of the waste liquid requiring recycling, and the funnel shape of the waste liquid register also facilitates the flow of as much waste liquid as possible into the subsequent waste liquid recycling area.

[0029] When the processing unit receives a waste liquid recovery signal, it opens the storage inlet of the waste liquid storage area to receive the waste liquid to be recovered based on the waste liquid recovery signal. This process of opening the storage inlet of the waste liquid storage area to receive the waste liquid to be recovered includes the following steps: Step S101: Start the imaging device based on the waste liquid recycling signal to obtain an internal image of the waste liquid storage area. Based on the internal image, determine whether there is residual liquid in the waste liquid storage area. If not, open the storage inlet of the waste liquid storage area to receive the waste liquid to be recycled.

[0030] Step S102: If yes, generate a residual liquid recovery signal to recover the residual liquid, and after the residual liquid recovery is completed, open the storage inlet of the waste liquid storage area to receive the waste liquid to be recovered.

[0031] Upon receiving a waste liquid recovery signal, the processing unit immediately activates the imaging device, which uses its built-in light to capture an image of the interior of the waste liquid storage area. This image is then sent to the image processing software associated with the processing unit. The software processes the image to determine if residual liquid is present, and sends this result back to the processing unit. Based on this result, the processing unit can then determine whether residual liquid remains in the waste liquid storage area.

[0032] If the received result indicates that there is no residual liquid in the internal image, then there is no residual liquid in the waste liquid storage area. In this case, the waste liquid to be recycled can be directly placed into the waste liquid storage area. This waste liquid storage area will not cause any further reaction of the waste liquid to be recycled, thus eliminating any potential hazard. That is, when it is determined that there is no residual liquid in the waste liquid storage area, the processing unit generates a signal to open the storage inlet, thus opening the storage inlet of the waste liquid storage area and entering a state for receiving the residual liquid to be recycled. At this time, the experimenter pours the waste liquid to be recycled into the waste liquid storage area through this inlet to receive the waste liquid to be recycled.

[0033] If the received result indicates that there is residual liquid in the internal image, then there is residual liquid in the waste liquid storage area. In order to avoid the waste liquid to be recycled reacting with the residual liquid in the waste liquid storage area and causing potential danger to the waste liquid storage area, a residual liquid recycling signal needs to be generated to recycle the residual liquid. After the residual liquid recycling is completed, the processor generates a signal to open the storage inlet to open the storage inlet of the waste liquid storage area, and puts it into the state of receiving the residual liquid to be recycled. At this time, the experimenter pours the waste liquid to be recycled into the waste liquid storage area through the storage inlet to receive the waste liquid to be recycled.

[0034] The process of generating a residual liquid recovery signal to recover the residual liquid includes the following steps: Step S102-1: Determine the type of residual liquid based on the internal image. If the residual liquid type only includes solid residual liquid, generate a solid residual liquid recovery signal. Open the storage inlet of the waste liquid storage area based on the solid residual liquid recovery signal to retrieve the residual liquid for recycling.

[0035] Step S102-2: If the residual liquid type includes liquid residual liquid, obtain the residual liquid recycling area corresponding to the residual liquid, generate a corresponding liquid residual liquid recycling signal based on the residual liquid recycling area, and open the connection channel between the residual liquid storage area and the residual liquid recycling area based on the liquid residual liquid recycling signal, so as to recycle the residual liquid into the residual liquid recycling area.

[0036] Step S102-3: Obtain the recycling image of the waste liquid storage area, determine whether the recycling image contains solid residue, if so, generate a solid residue recycling signal, and open the storage inlet of the waste liquid storage area based on the solid residue recycling signal to take out the residue for recycling.

[0037] When processing internal images, the image processing software outputs results indicating whether the residual liquid is purely liquid, purely solid, or a mixture of both. If the residual liquid is determined to be purely solid, it means the inner diameter of the storage outlet is smaller than the size of the solid residue. In this case, the processing unit generates a solid residue recovery signal to open the storage inlet of the waste liquid storage area and generates a "no waste liquid received" message. This prompts the operator to use a gripping device to remove the solid residue and place it at a fixed position in the recovery device for recycling. Once the solid residue is removed, the "no waste liquid received" message is no longer generated.

[0038] If the residual liquid is determined to contain liquid residue, regardless of whether it also contains solid residue, the liquid residue must be recovered first. Then, it must be determined whether the waste liquid storage area still contains solid residue. Finally, it is decided whether to open the storage inlet of the waste liquid storage area to retrieve the solid residue for recovery. Since the residual liquid is the remaining waste liquid from the previous waste liquid recovery, the specific waste liquid recovery area was determined during the previous recovery. Therefore, the aforementioned residual liquid recovery area is the area where the waste liquid was recovered last time. This can be obtained by checking the target waste liquid recovery area determined in the previous processing stage. Then, a liquid residual liquid recovery signal is generated to open the recovery inlet and storage outlet of the residual liquid recovery area, thereby opening the connection channel between the residual liquid storage area and the residual liquid recovery area. This allows the liquid residue in the waste liquid storage area to flow into the residual liquid recovery area, achieving safe recovery of the liquid residue in the residual liquid recovery area.

[0039] After the liquid residue is completely recycled into the residue recycling area, a camera is used to take another picture of the interior of the waste liquid storage area to obtain a recycling image. Then, the above method is used to determine whether the recycling image still contains solid residue. If not, the safe recycling of all residue is complete. If solid residue is still present, the storage inlet of the waste liquid storage area is opened using the method described in step S102-1 to retrieve and recycle the solid residue. This ensures that the waste liquid storage area can safely receive the waste liquid to be recycled, reducing the possibility of danger.

[0040] The waste liquid storage area is closed before receiving a waste liquid recycling signal and after receiving waste liquid to be recycled. It is only opened when needed, which reduces the contact time between the waste liquid to be recycled and the laboratory space, thus reducing the harm to personnel in the laboratory.

[0041] Step S200: Obtain the information on the waste liquid to be recycled and the information on the waste liquid already recycled in each waste liquid recycling area, and determine the target waste liquid recycling area where the waste liquid to be recycled needs to be stored based on the information on the waste liquid to be recycled and the information on the waste liquid already recycled.

[0042] After the waste liquid to be recycled is placed in the waste liquid storage area, the detection equipment in the storage area will detect the waste liquid to be recycled and send the detected information to the processing end, so that the processing end can obtain the recycling information of the waste liquid to be recycled. This recycling information includes the volume of the waste liquid to be recycled, the substances in the waste liquid to be recycled, and the concentration or mass of each substance in the waste liquid to be recycled. Obtaining the recycling information of the waste liquid to be recycled includes the following steps: Step S201: Use a liquid detector to obtain the liquid substance and its concentration in the waste liquid to be recycled.

[0043] Step S202: Use a camera to obtain the volume of the waste liquid to be recycled.

[0044] Step S203: Use a solid detector and imaging device to obtain the solid matter and the mass of the solid matter in the waste liquid to be recycled.

[0045] A liquid detector is a sensor capable of detecting soluble substances in a liquid and their concentration, while a solid detector is a sensor capable of detecting insoluble substances in a liquid and their concentration. A solid detector can specifically be a turbidimeter. In operation, a liquid detector can identify the liquid substances present in the waste liquid to be recycled and their concentrations, thus obtaining the composition and concentration of the liquid substances in the waste liquid.

[0046] The waste liquid to be recycled will cover the scale lines in the waste liquid storage area accordingly. Therefore, the volume of the waste liquid to be recycled can be obtained by looking at the minimum value of the scale lines shown in the image captured by the imaging device.

[0047] When operational, the solids detector can identify the solid substances in the waste liquid to be recycled, thus determining the composition of the solids. It also uses images captured by an imaging device to determine the size of each solid substance, and combines this with the corresponding density to calculate the mass of each solid substance.

[0048] Due to gravity, solid substances eventually settle to the center of the bottom of the waste liquid storage area. By fixing the solid detector at the center of the bottom of the waste liquid storage area, comprehensive detection of solid substances is easily achieved. During the process of pouring the waste liquid to be recycled into the waste liquid storage area, the imaging device captures a series of images, allowing the identification of the corresponding solid substance's size within these images. The liquid detector is placed on the side wall near the bottom, enabling even small volumes of waste liquid to be immersed in the waste liquid without affecting the solid detector's operation. This ensures that the liquid substances and their concentrations are obtained comprehensively and independently each time.

[0049] The aforementioned recovered information refers to the recovered volume, recovered substances, and concentration or mass of each recovered substance in the waste liquid recovery area. Specifically, the recovered information can be obtained by substituting the pending recovery information of the waste liquid already received in the waste liquid recovery area into a preset chemical group. Figure 4 This is a block diagram of a method for determining the target waste liquid recycling area that needs to be recycled based on the information to be recycled and the information already recycled, provided in an embodiment of this application. For example... Figure 4As shown, determining the target waste liquid recycling area where the waste liquid to be recycled needs to be recycled based on the information to be recycled and the information already recycled includes the following steps: Step S204: Substitute each piece of recovered information and the piece of information to be recovered into a preset chemical group to obtain the reaction information after each piece of recovered information reacts with the waste liquid information to be recovered.

[0050] Step S205: Determine whether there are any set classification requirements stored. If not, determine whether each reaction information meets the industry classification requirements and determine the target waste liquid recycling area from the waste liquid recycling areas that meet the industry classification requirements.

[0051] Step S206: If so, determine whether each reaction information meets the set classification requirements, and determine the target waste liquid recovery area from the waste liquid recovery areas that meet the set classification requirements.

[0052] The aforementioned preset chemical groups contain the chemical reaction formulas for each type of chemical reaction at this stage. Based on each piece of recovered and unrecovered information, the corresponding chemical reaction formulas are selected from the preset chemical groups and substituted into these formulas to obtain the reaction information after the reaction between each piece of recovered information and the unrecovered waste liquid information. This reaction information includes the substances in the waste liquid after the reaction, the concentration or mass of each substance, and the volume of the waste liquid.

[0053] Setting classification requirements specifically refers to the user's requirements for waste liquid mixing. These requirements must meet industry-specific classification needs while also having specific user requirements. This can be determined by checking if any classification requirements are stored in the processing terminal. If so, it indicates that classification requirements are stored; otherwise, they are not. When no classification requirements are stored, each reaction record is checked to see if it meets the industry-specific classification requirements, thus identifying which waste liquid recycling areas meet these requirements. The target waste liquid recycling area is then determined from among these meeting the classification requirements. Conversely, when classification requirements are stored, each reaction record is checked to see if it meets these requirements, thus identifying which waste liquid recycling areas meet these requirements. The target waste liquid recycling area is the waste liquid recycling area where the waste liquid to be recycled needs to be recovered.

[0054] The process of identifying target waste liquid recycling areas from those that meet industry classification requirements includes the following steps: Step S205-1: Determine the waste liquid recycling area that meets the industry classification requirements as the candidate waste liquid recycling area, obtain the candidate quantity of the candidate waste liquid recycling area, and if the candidate quantity is zero, determine the emergency recycling area in the recycling device as the target waste liquid recycling area.

[0055] Step S205-2: If the number of candidates is one, the candidate waste liquid recycling area is determined as the target waste liquid recycling area.

[0056] Step S205-3: If the number of candidates is greater than one, obtain the remaining capacity and the amount of substances contained in the reaction information corresponding to each candidate waste liquid recycling area, and determine the candidate waste liquid recycling area with a remaining capacity greater than the volume of the waste liquid to be recycled as the candidate waste liquid recycling area.

[0057] Step S205-4: Determine the candidate waste liquid recycling area with the smallest amount of substance among all the candidate waste liquid recycling areas as the target waste liquid recycling area.

[0058] The selection of potential waste liquid recycling areas can be determined by adding candidate keywords to waste liquid recycling areas that meet industry classification requirements. The number of candidate areas can then be obtained from the candidate keywords. If the number of candidate areas is zero, it means that placing the waste liquid to be recycled into any of the current waste liquid recycling areas does not meet the industry classification requirements. In this case, the emergency recycling area in the recycling device is determined as the target waste liquid recycling area.

[0059] If the number of candidates is one, it means that placing the waste liquid to be recycled into the candidate waste liquid recycling area can meet the industry classification requirements. In this case, this candidate waste liquid recycling area is determined as the target waste liquid recycling area.

[0060] If the number of candidate waste liquids is greater than one, it indicates that placing the waste liquid to be recycled into these candidate waste liquid recycling zones can meet the industry's classification requirements. In this case, obtain the total recycling capacity of each candidate waste liquid recycling zone and the volume of the waste liquid in the reaction information. Subtract the volume of the waste liquid from the total recycling capacity of the corresponding candidate waste liquid recycling zone to obtain the remaining capacity of that zone. Furthermore, by checking the quantity of substances in the solution in the reaction information, the quantity of substances contained in the reaction information can be obtained. Subsequently, candidate waste liquid recycling zones with remaining capacities greater than the volume of the waste liquid to be recycled are labeled with candidate keywords to obtain candidate waste liquid recycling zones. These candidate waste liquid recycling zones represent areas that both meet the industry's Ferreira requirements or set classification requirements and can accommodate all the waste liquid to be recycled.

[0061] To further enhance safety, by examining the reaction information corresponding to each candidate waste liquid recovery zone, the quantity of substances corresponding to each zone can be determined. The candidate waste liquid recovery zone with the lowest quantity of substances among all zones is then identified as the target waste liquid recovery zone. In this way, while meeting basic recovery requirements, the waste liquid recovery zone with the lowest quantity of substances after recovery is prioritized, thereby further improving safety.

[0062] Step S300: Generate a corresponding target waste liquid storage signal based on the target waste liquid recycling area, and open the connection channel between the waste liquid storage area and the target waste liquid recycling area based on the target waste liquid storage signal, so as to recycle the waste liquid to be recycled in the target waste liquid recycling area.

[0063] Once the target waste liquid recovery area is determined, a target waste liquid storage signal is generated corresponding to that area. Based on this signal, the recovery inlet of the waste liquid recovery area is opened, establishing a connection between the waste liquid storage area and the target waste liquid recovery area, thus allowing the waste liquid to be recovered to be placed in the target waste liquid recovery area. In this way, the recovery device automatically and safely places the waste liquid to be recovered into a safe waste liquid recovery area, eliminating the need for laboratory management personnel and achieving low-cost and safe waste liquid recovery.

[0064] Preferably, each waste liquid recycling area corresponds to a reagent bottle recycling area. When the waste liquid is recycled in the target waste liquid recycling area, the corresponding reagent bottle is also recycled in the reagent bottle recycling area corresponding to the target waste liquid recycling area, thereby reducing the pollution and potential hazards caused by the reagent bottles to the laboratory.

[0065] This application also provides a capacity monitoring and early warning method, which uses the above-mentioned laboratory hazardous waste liquid classification and recycling method to classify and recycle waste liquid in the laboratory. Figure 5 This is a block diagram of a capacity monitoring and early warning method provided in this application. Figure 5 As shown, a capacity monitoring and early warning method includes the following steps: Step S400: Obtain the historical waste liquid volume of each waste liquid recovery zone in the recycling device for each recovery, and fit all historical waste liquid volumes to obtain the waste liquid volume change curve corresponding to each waste liquid recovery zone.

[0066] Step S500: Obtain the total storage capacity and the stored waste liquid capacity of each waste liquid recycling zone in the recycling device.

[0067] Step S600: Determine the remaining capacity of each waste liquid recycling zone based on the total storage capacity and waste liquid capacity of each waste liquid recycling zone.

[0068] Step S700: Predict the future volume to be recycled for each waste liquid recycling zone based on the volume change curve of the recycled waste liquid corresponding to each waste liquid recycling zone.

[0069] Step S800: Determine whether the future volume to be recycled in the same waste liquid recycling area is not greater than the remaining capacity. If not, generate an early warning signal to handle the recycling device.

[0070] Step S900: If yes, continue to obtain the total storage capacity and the stored waste liquid capacity of each waste liquid recycling zone in the recycling device.

[0071] The aforementioned historical waste liquid volume refers to the volume of waste liquid that has already been recycled. The processing end stores information on the residual liquid from each recycling cycle. By viewing the information stored at the processing end, the historical waste liquid volume of each waste liquid recycling zone in the recycling device can be obtained. Then, by using a data fitting method to fit the historical waste liquid volumes corresponding to the same waste liquid recycling zone, the waste liquid volume change curve corresponding to each waste liquid recycling zone can be obtained.

[0072] The total storage capacity mentioned above refers to the maximum capacity of waste liquid that can be recycled in this waste liquid recycling area. The storage capacity of individual waste liquids refers to the capacity of waste liquid that has already been recycled in this waste liquid recycling area. The total storage capacity and the stored waste liquid capacity of each waste liquid recycling area can be obtained by viewing the information stored at the processing terminal.

[0073] Then, by subtracting the stored waste liquid volume from the total storage capacity of the corresponding waste liquid recycling zone, the remaining capacity of that waste liquid recycling zone can be obtained. The remaining capacity refers to the capacity of the waste liquid recycling zone that can still recycle residual liquid. The volume change curve for each recycled waste liquid represents the trend of the waste liquid volume that has been recycled each time, and includes a predicted value for the future volume of waste liquid to be received. The predicted future volume to be recycled for each waste liquid recycling zone can be obtained by viewing the volume change curve for that zone.

[0074] Next, the future volume to be recycled in the same waste liquid recycling zone is compared with the remaining capacity. If the future volume to be recycled in all waste liquid recycling zones is no greater than the remaining capacity, it indicates that the recycling device can still recycle the waste liquid to be recycled next time. At this time, the processing end continues to obtain the total storage capacity and the stored waste liquid capacity of each waste liquid recycling zone in the recycling device. Otherwise, it indicates that the recycling device may not be able to recycle the waste liquid to be recycled next time. In order to reduce the potential danger, the processing end generates a warning signal to deal with the recycling device.

[0075] Figure 6 This is a schematic diagram illustrating the connection of a laboratory hazardous waste liquid sorting and recycling system provided in an embodiment of this application. The system is applied to a recycling device with multiple waste liquid recycling areas, the recycling device including a waste liquid storage area and multiple waste liquid recycling areas, such as... Figure 6 As shown, a laboratory hazardous waste liquid classification and recycling system includes: an acquisition module, a storage module, a classification module, and a recycling module.

[0076] The system comprises the following modules: an acquisition module for acquiring waste liquid recycling signals; a storage module for opening the storage inlet of the waste liquid storage area based on the waste liquid recycling signals to receive the waste liquid to be recycled; a classification module for acquiring information on the waste liquid to be recycled and the already recycled information in each waste liquid recycling area, and determining the target waste liquid recycling area where the waste liquid to be recycled should be collected; and a recycling module for generating a corresponding target waste liquid storage signal based on the target waste liquid recycling area, and opening the connection channel between the waste liquid storage area and the target waste liquid recycling area based on the target waste liquid storage signal to collect the waste liquid to be recycled in the target waste liquid recycling area.

[0077] Figure 7 This is a schematic diagram of the connection of a capacity monitoring and early warning system provided in an embodiment of this application. The capacity monitoring and early warning system uses the aforementioned laboratory hazardous waste liquid classification and recycling method to classify and recycle waste liquids in the laboratory. For example... Figure 7 As shown, a capacity monitoring and early warning system includes: a monitoring module, a processing module, and an early warning module.

[0078] The system includes a monitoring module to acquire the historical waste liquid volume recovered in each waste liquid recovery zone of the recycling device, as well as the total storage capacity and stored waste liquid capacity of each waste liquid recovery zone. A processing module is used to fit all historical waste liquid volumes to obtain a waste liquid volume change curve for each waste liquid recovery zone, determine the remaining capacity of each waste liquid recovery zone based on its total storage capacity and waste liquid capacity, and predict the future volume to be recovered for each waste liquid recovery zone based on its corresponding waste liquid volume change curve. An early warning module determines whether the future volume to be recovered for the same waste liquid recovery zone is less than the remaining capacity. If not, an early warning signal is generated to address the issue; otherwise, the system continues to acquire the total storage capacity and stored waste liquid capacity of each waste liquid recovery zone.

[0079] The other functions performed by the above-mentioned acquisition module, storage module, classification module, recycling module, monitoring module, processing module, and early warning module, as well as the technical details of each function, are the same as or similar to the corresponding features in the previously described laboratory hazardous waste liquid classification and recycling method and capacity monitoring and early warning method, so they will not be repeated here.

[0080] It should be understood that although the steps in the flowcharts in the accompanying figures are shown sequentially as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order requirement for the execution of these steps, and they can be performed in other orders.

[0081] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
