Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of radioactive material treatment, and in particular to an intelligent treatment system for radioactive waste liquid. Background Art
[0002] With the rapid development of nuclear medicine, radionuclides are widely used in disease diagnosis and treatment. For example, imaging technologies such as PET-CT and SPECT are indispensable in the diagnosis and treatment of tumors, cardiovascular diseases, and neurological diseases. This growing demand has led to an annual increase in the use of radionuclides, but it has also brought about severe challenges in the management of radioactive waste.
[0003] Radioactive liquid waste is a by-product of nuclear medicine activities. The main sources include:
[0004] Residual liquid from radionuclide drugs for injection in hospitals.
[0005] Cleaning wastewater from nuclear medicine imaging equipment.
[0006] Radioactive substances excreted in the patient's urine or excreta.
[0007] These wastes are characterized by high hazard, long-term and complex nature:
[0008] High hazard: Untreated waste liquid may directly cause radiation pollution to the ecological environment and human health.
[0009] Long-term: Some radionuclides have a long half-life, and the radioactivity in the waste liquid needs to be monitored over a long period of time.
[0010] Complexity: The wastewater may contain mixed radionuclides, and treatment requires targeted technology.
[0011] With the rapid development of the Internet of Things and artificial intelligence technologies, intelligent wastewater management has gradually become a research hotspot. For example:
[0012] Automated drainage system: Some hospitals have introduced automated waste liquid collection equipment, but most of them remain at the basic automatic discharge level and fail to achieve in-depth treatment of waste liquid.
[0013] Radiation detection technology: There are online monitoring devices based on radioactive detectors, but most of them are separated from waste liquid treatment equipment and cannot form a unified closed-loop system.
[0014] Industrial waste liquid treatment system: In the chemical industry, intelligent waste liquid separation equipment has achieved a certain degree of automation, but it is not targeted enough and cannot be directly applied to radioactive waste liquid treatment.
[0015] Shortcomings of existing technology
[0016] The current methods for treating radioactive waste liquid mainly include dilution discharge, sedimentation, adsorption and solidification, but they still have obvious defects:
[0017] Inefficiency: Traditional technologies mostly rely on manual operations or single chemical treatment methods, and cannot achieve efficient and automated waste liquid treatment.
[0018] Incomplete monitoring: In the existing system, radioactivity monitoring is disconnected from the treatment steps, making it difficult to track changes in waste liquid activity in real time.
[0019] High treatment cost: The treatment of some high-activity waste liquids requires special materials or equipment, which is expensive.
[0020] Insufficient environmental protection: Some treatment methods may cause secondary pollution. For example, the adsorption method will produce solid waste containing radioactive adsorption materials.
[0021] Therefore, the present invention provides an intelligent treatment system for radioactive liquid waste. Summary of the Invention

[0085] In this example, the radiology discipline may be nuclear medicine;
[0086] In this example, basic work data refers to publicly available data generated by the radiology department when performing various types of work;
[0087] In this example, the specified time period is 24 hours, and the relevant processing personnel can also adjust the specific length of the specified time period according to the work frequency of the radiology discipline;
[0088] In this example, the waste liquid collection measure refers to the measure for uniformly collecting the waste liquid generated by the radiology department;
[0089] In this example, estimating the radioactivity of the waste liquid means analyzing the working conditions of the radiology department based on basic working data, thereby estimating the radioactivity of the generated waste liquid;
[0090] In this example, the amount of waste liquid generated means analyzing the work situation of the radiology department based on basic work data to estimate the amount of waste liquid generated;
[0091] In this example, the waste liquid detection method refers to a method used to detect the precise radioactivity of the waste liquid;
[0092] In this example, the nuclide activity value represents the decay rate of the radioactive material in the wastewater;
[0093] In this example, the wastewater grades are divided into two categories: high activity grade and low activity grade;
[0094] In this instance, the supervisory data represents the data generated during the active processing;

[0096] In this example, the post-processing radioactivity refers to the radioactivity of the substance produced after the active treatment;
[0097] In this example, the generated treated product refers to a substance generated after the waste liquid is subjected to active treatment.
[0098] The working principle and beneficial effects of the above technical solution are as follows: in order to improve the efficiency and quality of waste liquid treatment and avoid secondary pollution, when working in the radiological discipline, the amount of waste liquid generated within a period of time and the radioactive activity of the waste liquid are preliminarily analyzed based on its basic work data, so as to construct corresponding waste liquid collection measures to collect the waste liquid, eliminating the risk of waste liquid leakage from the source, and then detecting the radionuclide activity value of the waste liquid, dividing the waste liquid into grades according to the radionuclide activity value, and transporting waste liquid of different grades to different treatment areas for different treatments to improve the treatment efficiency.

[0106] The working principle and beneficial effects of the above technical solution: In order to further ensure the quality of waste liquid treatment and avoid secondary pollution caused by waste liquid leakage, the real-time position of the waste liquid is tracked during the waste liquid treatment process to determine the next flow container of the waste liquid. Before the waste liquid reaches the next container, it is subjected to a sealing test to determine the sealing performance of the container. When the sealing performance of the container is low, the waste liquid is prevented from continuing to flow to avoid leakage.
[0107] Example 3
[0108] Based on Example 1, the intelligent treatment system for radioactive liquid waste, the waste liquid collection module, includes:

[0123] In this example, the collection rate is determined by the size of the opening at the input end of the radiation-resistant container. The larger the opening, the higher the collection rate.
[0124] The working principle and beneficial effects of the above technical solution are as follows: In order to collect waste liquid in an orderly manner and avoid leakage, a basic working model needs to be established based on the basic working data of the radiology department before collection. The waste liquid generating equipment is located in the basic working model, and then the operating parameters of each waste liquid generating equipment are identified. At the same time, the initial radioactive materials of the radiology department are identified. The estimated radioactive activity of the waste liquid generated this time is analyzed based on the initial radioactive activity of the initial radioactive materials combined with their corresponding activity dissipation characteristics. The estimated generation volume of the waste liquid generated this time is estimated based on the operating parameters of the waste liquid generating equipment, so as to select the container for collecting the waste liquid this time and the collection rate, and construct a feasible waste liquid collection measure. According to this measure, waste liquid collection can be achieved synchronously, and the corresponding containers are configured by estimating the generation volume and activity of the waste liquid. This can not only reasonably allocate resources, but also extend the service life of each container, thereby improving the availability and practicality of the system.
[0125] Example 4
[0126] On the basis of Example 1, the intelligent treatment system for radioactive waste liquid, the radiation detection module, such as Figure 2 Shown, including:
[0127] a mode configuration unit, configured to determine an estimated activity range of the waste liquid based on the estimated radioactivity of the waste liquid, search for a basic detection mode corresponding to the estimated radioactivity of the waste liquid, adjust detection parameters of a preset radioactivity detector according to the estimated activity range, determine a sampling frequency of the waste liquid based on the estimated amount of waste liquid generated, and modify the basic detection mode based on the detection parameters and the sampling frequency to obtain a waste liquid detection mode;

[0129] an activity analysis unit, configured to input each of the sampled detection results into the sampling matrix, connect the sampling element bits corresponding to any two sampled detection results in the sampling matrix to obtain a number of correlated element bits corresponding to each connection, and match the corresponding estimated activity value to the correlated element bits of the corresponding connection based on the result difference between different sampled detection results;
[0130] an error identification unit, configured to locate cross element positions between different lines, obtain a number of target cross element positions whose number of estimated activity values is not 1, and perform variance calculation on a number of target estimated activity values corresponding to the target cross element positions to obtain a replacement activity value corresponding to each target cross element;
[0131] An acquisition calibration unit is configured to regard the sampling element bits and cross element bits in the sampling matrix as fixed element bits, determine a number of non-fixed element bits contained in the sampling matrix, numerically adjust the non-fixed element bits according to the fixed activity value corresponding to each of the fixed element bits to obtain the activity matrix of the waste liquid, and generate the nuclide activity value of the waste liquid according to the activity matrix.
[0132] In this example, the estimated activity range refers to the range of the actual radioactivity of the waste liquid determined by estimation;
[0133] In this example, the basic detection method refers to the process of controlling the preset radioactive detector to adjust from the maximum threshold value of the detection parameter to the minimum threshold value of the detection parameter to perform activity detection;
[0134] In this example, the preset radioactive detector may be a scintillation detector or a semiconductor detector;
[0135] In this example, the number of sampling times is related to the estimated waste liquid generation volume. The number of sampling times increases by one for every 3L increase in the estimated waste liquid generation volume.
[0136] In this example, the waste liquid needs to be sampled evenly during sampling;
[0137] In this example, the related element bit represents an element bit that a line passes through, and the related element bit represents a related element between the sample element bits of any two detection results;
[0138] In this example, the cross element bit represents the element bit corresponding to the intersection of two or more lines;
[0139] In this example, estimating the activity value means determining the value corresponding to the relevant element position by inference;
[0140] In this example, the target cross element bit identifies the cross element bit containing two or more estimated activity values;
[0141] In this example, replacing the activity value means using the result of variance calculation of the target estimated activity value corresponding to a target cross element position to replace the target estimated activity value data at the target cross element position;
[0142] In this example, a fixed element bit indicates that the data value corresponding to the element bit is fixed;
[0143] In this example, a non-fixed element bit indicates that the data value at the element bit needs to be adjusted;
[0144] In this example, the process of adjusting the values of the non-fixed element positions using the fixed activity value is as follows: iteratively deriving the values of the non-fixed element positions, then re-determining the fixed element positions, and then iterating the values again.
[0145] The working principle and beneficial effects of the above technical solution: In order to quickly determine the radionuclide activity value of the waste liquid and avoid the uneven distribution of radionuclides in the waste liquid affecting the test results, before the test, the estimated activity range of the waste liquid is determined according to the estimated radioactive activity of the waste liquid, the detection parameters of the radioactive detector are determined, and the sampling times are determined according to the amount of waste liquid generated, so as to adjust the basic detection method, adjust the detection parameters and the sampling times, and generate a waste liquid detection method suitable for this test, so that the waste liquid is sampled under the guidance of the detection method, and the activity of each sample is detected. In order to more intuitively and conveniently deduce the activity value of the remaining waste liquid, the detection parameters of the waste liquid are adjusted according to the waste liquid. The sampling matrix is established by the sampling arrangement of the samples, and the sampling test results are further input into the sampling matrix. The relevant element positions between any two sampling test results are determined by the connection method, so as to deduce the estimated activity value of each relevant element position, and further the numerical value of each cross element position containing multiple estimated activity values is refined to a fixed value, and finally the activity matrix of the waste liquid is obtained. In this way, the activity value of each part of the waste liquid can be determined, so as to deduce the accurate nuclide activity value of the waste liquid. In this way, the interference of uneven nuclide distribution on the test results can be effectively avoided, the management difficulty is reduced, and the downtime or delay caused by improper waste liquid treatment is reduced.

[0149] a processing execution unit, configured to perform active treatment on the waste liquid in the processing area and collect monitoring data during the active treatment process;
[0150] An information construction unit is used to analyze the activity values corresponding to the waste liquid at different times according to the supervision data, establish an activity change chart of the waste liquid, and mark the coded label on the activity change chart to generate the nuclide activity value change information of the waste liquid.
[0151] In this example, the activity attribute includes a high activity attribute and a low activity attribute;
[0152] In this example, the activity variation chart represents a chart showing the variability of the activity value composition of the waste liquid at different times.
[0153] The working principle and beneficial effects of the above technical solution are as follows: when treating waste liquid, different degrees of treatment are performed on waste liquids with different activities, which can reduce the cost of waste liquid treatment and improve the treatment efficiency, especially when the proportion of high-activity waste liquid is small.
[0154] Example 6
[0155] Based on Example 5, the intelligent treatment system for radioactive liquid waste, the processing execution unit includes:

[0157] A low-activity processing subunit is used to dilute the waste liquid when the activity attribute of the waste liquid is low activity attribute, so as to obtain qualified liquid that meets the specified standards;
[0158] It is also used to dilute the low-activity liquid to obtain a qualified liquid that meets regulations.
[0159] In this example, the neutralizing liquid refers to the liquid used to neutralize the pH of the waste liquid;
[0160] In this instance, the prescribed standards are: compliance with local laws and regulations and social responsibility ordinances;
[0161] In this example, high-activity waste liquid is converted into stable solids through solidification technology, and low-activity waste liquid is diluted and discharged to an area that meets national standards.
[0162] The working principle and beneficial effects of the above technical solution are as follows: by subjecting waste liquids of different activities to different treatments, the waste liquids can be quickly processed into qualified liquids, and the dependence on high-cost treatment technologies can be reduced through intelligent diversion, and targeted treatment strategies can be adopted to avoid waste of resources.

[0168] Based on Example 1, the intelligent treatment system for radioactive liquid waste, the in-depth treatment module, includes:
[0169] a tracking and analysis unit, configured to obtain corresponding generated processed products after the waste liquid has completed the activity treatment, and determine corresponding treatment activity values of the generated processed products at different times according to the nuclide activity value change information;
[0170] a depth analysis unit for establishing a time axis of activity variation of the generated processed product and identifying a processing dissipation feature of the generated processed product in the activity variation time axis;
[0171] The storage execution unit is used to determine the hazardous radiation level of the generated processed object according to the processing dissipation characteristics, and transport the generated processed object to a radiation storage area of the corresponding level for storage.
[0172] In this example, the process dissipation characteristic represents the dissipation of the activity of the process product generated during the active process.
[0173] The working principle and beneficial effects of the above technical solution: In order to further ensure the quality of system processing and reduce the risk of leakage, after completing the active treatment, the treatment dissipation characteristics of the generated processed material are analyzed according to the corresponding treatment activity values of the generated processed material at different times, and the hazardous radiation level of the generated processed material is further determined based on the treatment dissipation characteristics, so that the generated processed material is transferred to the corresponding radiation storage area for storage. In this way, the risk of radiation leakage caused by human omissions or operational errors during the waste liquid treatment process can be avoided, and safety can be greatly improved.

[0176] A collection monitoring module, configured to determine a minimum amount of waste liquid generated within the specified time period based on the waste liquid collection measures;
[0177] Counting the real-time cumulative amount of the waste liquid to determine the actual amount of waste liquid generated within the specified time period;
[0178] When the actual waste liquid generation amount is lower than the minimum waste liquid generation amount, it is determined that the waste liquid collection operation is abnormal, and an abnormality warning is issued.
[0179] In this example, the actual amount of waste liquid generated refers to the actual amount of waste liquid discharged by the radiology department.
[0180] The working principle and beneficial effects of the above technical solution: Since the waste liquid contains radioactive substances, it has certain hazards to the environment and human body. When collecting waste liquid, if the collected waste liquid is significantly less than the amount generated by the radiological discipline, an early warning will be issued to remind relevant personnel to deal with it as soon as possible to avoid danger.

[0184] The working principle and beneficial effects of the above technical solution: During the treatment of waste liquid, when the waste liquid meets the emission standards, the treatment work is stopped, which can effectively reduce irrelevant workload and improve the intelligence of the system.
