Description

A treatment device and system for iodine-containing wastewater from decay ponds. Technical Field

[0001] This invention relates to the field of radionuclide adsorption equipment in decay pools, and specifically to a radioactive iodine wastewater treatment device for nuclear medicine departments built on decay pools, specifically a treatment device and system for iodine-containing nuclear wastewater in decay pools. Background Technology

[0002] The hospital's nuclear medicine department primarily undertakes two major functions: detection and treatment. One is radionuclide diagnostic imaging and detection, using radioactive tracers (such as 18F-FDG, ...). 99m Tc-MDP is injected into the human body, and functional metabolic imaging is performed using a gamma camera or PET / CT, breaking through the limitations of traditional imaging that only displays anatomical structures. For example, in tumor diagnosis, PET-CT can detect abnormal glucose metabolism in cancer cells 3-6 months in advance (sensitivity > 90%). In cardiovascular assessment, myocardial perfusion imaging (…) 99m Tc-MIBI precisely locates ischemic areas; it is used for neurological diseases such as Alzheimer's disease. Secondly, targeted radionuclide therapy is based on the principle of "isotope targeted accumulation" caused by the thyroid gland's specific absorption of iodine, using high-energy rays to selectively kill diseased tissue. The most common application is for thyroid diseases: I131 treatment for hyperthyroidism and differentiated thyroid cancer (cure rate >85%). However, I131 is excreted through the kidneys as sodium iodide, primarily in urine. Therefore, each hospital's nuclear medicine department must have a separate decay pool. The construction of the decay pool must strictly adhere to the three principles of "separate collection, physical decay, and intelligent monitoring." In terms of site selection and structure, underground reinforced concrete pools (thickness ≥25cm) are used, lined with epoxy resin for impermeability, and located ≥20 meters from sensitive areas. The volume is determined by the type and quantity of radionuclides being detected and treated; theoretically, each pool in each hospital may have a capacity of 20-25 m³. For example, a daily processing capacity of 0.5 m³¹ 8 The volume of F-type wastewater must be ≥1.7m³; the decay tank must have at least 3 cells connected in series to ensure that the wastewater remains for ≥10 half-lives. Therefore, each hospital needs to use a very large decay tank to store these waste liquids containing radioactive iodine, which greatly increases the burden in terms of construction and maintenance.

[0003] However, the decay pools in many top-tier hospitals' nuclear medicine departments that have already been built are very limited in size, far below the national standard, and the excessively long storage time of nuclear wastewater severely restricts the development of nuclear medicine departments.

[0004] First, the volume of existing decay pools in hospitals is far below the volume required by national regulations. Second, existing decay pools are expensive, relatively large, and have high maintenance costs. Currently, decay pools under construction in tertiary hospitals are generally at least tens of cubic meters in volume. Third, the costs are high, often requiring a huge construction cost of 2 million to 5 million yuan and an annual maintenance cost of nearly 200,000 yuan.

[0005] Fourth: The size of the decay pool limits the development of the hospital's nuclear medicine department, making it impossible to provide more patients who need iodine-131 treatment with the opportunity to receive it.

[0006] In summary, existing decay pools suffer from high construction costs, large footprints, and inability to meet requirements. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0027] One embodiment relates to the processing device of the present invention.

[0028] As shown in FIG1, an illustrative embodiment of the present invention is a treatment device for iodine-containing nuclear wastewater in a decay pool, comprising a housing unit 100, an input unit 200, at least one pre-filtration unit 300, at least one radionuclide adsorption unit 400, and an output unit 500. The system comprises: an input unit 200 located inside the housing unit 100, connected to the decay pool for inputting nuclear wastewater; a pre-filtration unit 300 located inside the housing unit 100, at the rear end of the input unit 200, and connected to the input unit 200, for filtering the nuclear wastewater to remove particulate matter; a radionuclide adsorption unit 400 located inside the housing unit 100, at the rear end of the pre-filtration unit 300, and connected to the pre-filtration unit 300, for performing a radionuclide adsorption process on the filtered nuclear wastewater; and an output unit 500 located inside the housing unit 100, at the rear end of the radionuclide adsorption unit 400, and connected to the radionuclide adsorption unit 400, for connecting to the discharge pool to output the nuclear wastewater treated by the radionuclide adsorption process to the discharge pool.

[0029] In some embodiments, there are multiple pre-filter units 300. Each of the multiple pre-filter units 300 is connected to the input unit 200. That is, the multiple pre-filter units 300 are arranged in parallel.

[0030] In some embodiments, there are multiple radionuclide adsorption units 400. Each radionuclide adsorption unit 400 is connected to a corresponding pre-filter unit 300 and to an output unit 500. That is, multiple radionuclide adsorption units 400 are arranged in parallel.

[0031] The number of radionuclide adsorption units 400 matches the number of pre-filter units 300. Generally, the number of radionuclide adsorption units 400 is equal to the number of pre-filter units 300.

[0032] With multiple pre-filtration units 300 and multiple radionuclide adsorption units 400, several filtration adsorption groups are formed. Each filtration adsorption group includes one pre-filtration unit 300 and one radionuclide adsorption unit 400. The multiple filtration adsorption groups do not work simultaneously; that is, only one filtration adsorption group works at any given time. When the adsorption capacity of one filtration adsorption group reaches the preset adsorption capacity, that filtration adsorption group is turned off, and another filtration adsorption group is started.

[0033] Generally, the number of pre-filter units 300 and the number of radionuclide adsorption units 400 are set according to actual needs.

[0034] Generally, a single radionuclide adsorption unit 400 can meet the radionuclide adsorption requirements for approximately six months. This is mainly because the adsorption capacity of the radionuclide adsorption unit 400 is related to the amount of radionuclides in the nuclear wastewater, but not to the quantity of nuclear wastewater.

[0035] In this invention, the nuclide adsorption unit 400 mainly plays the role of nuclide enrichment.

[0036] As shown in Figure 2, the enclosure unit 100 includes an enclosure element 101 and several first protective elements 102. The enclosure element 101 is internally provided with an input unit 200, a pre-filter unit 300, a radionuclide adsorption unit 400, and an output unit 500. The several first protective elements 102 cover the enclosure element 101 and are used to isolate radioactivity.

[0037] The housing element 101 is generally a rectangular housing structure. Typically, the rear side of the housing element 101 abuts against the building wall, and the bottom of the housing element 101 abuts against the ground.

[0038] In some embodiments, the housing element 101 includes a rear panel, a front panel, a left panel, a right panel, a top panel, and a bottom panel. The front panel is disposed parallel to the front side of the rear panel; the left panel is disposed between the rear panel and the front panel and connected to both; the right panel is disposed parallel to the side of the left panel and between the rear panel and the front panel, and connected to both; the top panel is connected to the rear panel, the front panel, the left panel, and the right panel; and the bottom panel is disposed parallel to the upper part of the top panel and connected to the rear panel, the front panel, the left panel, and the right panel.

[0039] Furthermore, the housing element 101 also includes at least one door. The door is movably disposed on the front panel and is used to open for replacing the pre-filter unit 300 and the radionuclide adsorption unit 400 located in the housing element 101.

[0040] In some embodiments, there are multiple doors. Each door is movably disposed on the front panel and can be opened individually to replace the corresponding pre-filter unit 300 and radionuclide adsorption unit 400.

[0041] Doors can move in various ways, including rotating and sliding. Examples include revolving doors and sliding doors. Rotation and sliding are conventional techniques in this field and will not be elaborated upon here.

[0042] In some embodiments, the housing element 101 further includes a plurality of support feet. The plurality of support feet are distributed at the bottom end of the bottom panel to support the housing element 101 so that there is a certain gap between the bottom panel and the ground.

[0043] In some of these embodiments, housing element 101 includes, but is not limited to, a housing.

[0044] A number of first protective elements 102 are distributed on the inner and / or outer surfaces of the housing element 101.

[0045] For example, several first protective elements 102 are distributed at least on the front panel, left panel, right panel and top panel of the enclosure element 101. The main reason is that the rear panel of the enclosure element 101 abuts against the building wall and the bottom panel of the enclosure element 101 abuts against the ground.

[0046] When the rear panel of the enclosure element 101 does not abut against the building wall, the first protective element 102 is also provided on the rear panel of the enclosure element 101.

[0047] When the bottom plate of the enclosure element 101 is far from the ground, the first protective element 102 is also disposed on the bottom plate of the enclosure element 101.

[0048] The combination of the first protective element 102 and the housing element 101 can be achieved in the following ways: 1) The first protective element 102 is fixed to the inner surface and / or outer surface of the housing element 101 by means of bolt connection or other means; 2) The housing panel of the housing element 101 is a hollow structure, and the first protective element 102 is disposed inside the housing panel.

[0049] In some of these embodiments, the thickness of the first protective element 102 is at least 2 mm.

[0050] Preferably, the thickness of the first protective element 102 is 4 mm.

[0051] In some of these embodiments, the first protective element 102 includes, but is not limited to, a lead plate.

[0052] As shown in Figure 3, the input unit 200 includes an input pipe element 201, a pump element 202, and a first radioactivity detection element 203. The input pipe element 201 is located inside the housing unit 100, at the front end of the pre-filtration unit 300, and communicates with the pre-filtration unit 300. It is used to connect to the decay pool for inputting and outputting nuclear wastewater to the pre-filtration unit 300. The pump element 202 is located inside the housing unit 100 and communicates with the input pipe element 201, providing power to allow nuclear wastewater to enter the input pipe element 201 from the decay pool. The first radioactivity detection element 203 is located in the input pipe element 201 and is used to detect the radioactivity of the nuclear wastewater input to the input pipe element 201.

[0053] Specifically, the input pipe element 201 is disposed inside the housing element 101; the pump element 202 is disposed inside the housing element 101.

[0054] The input pipe element 201 is generally located inside the housing element 101. The inlet end of the input pipe element 201 can be embedded in the side wall (such as the left housing plate) or the bottom wall (such as the bottom housing plate) of the housing element 101, or the inlet end of the input pipe element 201 can be located on the outside of the housing element 101.

[0060] In some embodiments, the first radioactive detection element 203 includes, but is not limited to, radioactive sampling and detection equipment. For example, radiation safety monitoring equipment (Suzhou Zhongmin Radiation Safety Instrument Co., Ltd., model: DTM-100T).

[0061] Furthermore, the input unit 200 also includes a pressure detection element 204. The pressure detection element 204 is connected to the input pipeline element 201 and is used to detect pressure.

[0062] The pressure detection element 204 is located at the outlet end of the input pipe element 201, that is, in the second input pipe.

[0063] In some embodiments, the pressure sensing element 204 includes, but is not limited to, a pressure gauge. The structure and working principle of the pressure sensing element 204 are conventional techniques in the art and will not be described in detail here.

[0064] As shown in Figure 4, the pre-filtration unit 300 includes a first conveying pipe element 301, a pre-filtration element 302, and a second conveying pipe element 303. The first conveying pipe element 301 is located inside the housing unit 100, at the rear end of the input unit 200, and communicates with the input unit 200, for supplying nuclear wastewater. The pre-filtration element 302 is located inside the housing unit 100, at the rear end of the first conveying pipe element 301, and communicates with the first conveying pipe element 301, for performing a filtration process on the nuclear wastewater to remove particulate matter.

For example, there may be two elements 402: one is a pre-filter, and the other is a post-filter. The pre-filter is the primary filter, and the post-filter is the secondary filter. The pre-filter adsorbs most of the radionuclides in the wastewater (approximately 95%–98%), while the post-filter adsorbs the remaining radionuclides. Using two elements 402, the vast majority of the radionuclides in the wastewater (approximately 99% or more) can be adsorbed.

[0088] It should be noted that the specifications of the post-nuclear adsorption filter can be the same as or different from those of the pre-nuclear adsorption filter. Generally, the specifications (mainly volume) of the post-nuclear adsorption filter are not larger than those (mainly volume) of the pre-nuclear adsorption filter.

[0140] In this invention, two pre-filtration units 300 and two radionuclide adsorption units 400 are used as an example for explanation. One pre-filtration unit 300 and one radionuclide adsorption unit 400 form filtration adsorption group A, and the other pre-filtration unit 300 and the other radionuclide adsorption unit 400 form filtration adsorption group B. Filtration adsorption group A is turned on and filtration adsorption group B is turned off, so that the radioactive wastewater from the decay tank flows only to filtration adsorption group A, and the radioactive wastewater treated by filtration adsorption group A flows to the discharge tank. When filtration adsorption group A becomes saturated, filtration adsorption group A is turned off and filtration adsorption group B is turned on, so that the radioactive wastewater from the decay tank flows only to filtration adsorption group B, and the radioactive wastewater treated by filtration adsorption group B flows to the discharge tank.

[0141] The method of using this invention is as follows: (I) When the filtration and adsorption group A is working and the filtration and adsorption group B is not working, the first ball valve element 304, the second ball valve element 305, the inlet valve element 406, the third ball valve element 407, and the outlet valve element 408 of the filtration and adsorption group A are turned on; the nuclear wastewater from the decay tank enters the pre-filtration element 302 of the filtration and adsorption group A through the input pipeline element 201 and the first conveying pipeline element 301 for filtration; the nuclear wastewater treated by the filtration process enters the nuclide of the filtration and adsorption group A through the second conveying pipeline element 303 and the third conveying pipeline element 401. The adsorption element 402 performs the radionuclide adsorption process; the radioactive wastewater treated by the radionuclide adsorption process enters the waiting pool through the fourth conveying pipeline element 403 and the output pipeline element 501; (II) The filtration and adsorption group A is not working, and the filtration and adsorption group B is working. The control unit acquires the radioactivity data transmitted by the first radioactivity detection element 203, the second radioactivity detection element 405, and the third radioactivity detection element 502 in real time; the control unit compares the radioactivity data of the third radioactivity detection element 502 with the radioactivity data of the first radioactivity detection element 203. If the two radioactivity data are not significantly different... The control unit closes the first ball valve element 304, the second ball valve element 305, the inlet valve element 406, the third ball valve element 407, and the outlet valve element 408 of the filtration and adsorption group A, and opens the first ball valve element 304, the second ball valve element 305, the inlet valve element 406, the third ball valve element 407, and the outlet valve element 408 of the filtration and adsorption group B. The nuclear wastewater from the decay tank enters the pre-filtration element 302 of the filtration and adsorption group B through the input pipeline element 201 and the first conveying pipeline element 301 for filtration. The nuclear wastewater treated by the filtration process is then conveyed through the second conveying pipeline element 302. Pipeline element 303 and third conveying pipeline element 401 enter the radionuclide adsorption element 402 of the filtration and adsorption group B for radionuclide adsorption process; the nuclear wastewater treated by the radionuclide adsorption process enters the waiting tank through the fourth conveying pipeline element 403 and the output pipeline element 501; (III) Replacement / Maintenance When the adsorption capacity of both filtration and adsorption group A and filtration and adsorption group B reaches the upper limit, the machine is stopped, the pre-filter element 302 is maintained, and the radionuclide adsorption element 402 is replaced; after the replacement / maintenance is completed, the machine is restarted and steps (I) and (II) are repeated.

[0142] The present invention can achieve the following functions: Practicality: Preliminary test results show that the device can adsorb more than 95% of I in wastewater. 131 It can help expand the scale of the nuclear medicine department and ensure I 131 Wastewater discharge does not exceed standards; even with a reduced decay pool size in future nuclear medicine departments, the discharge of iodine-containing radioactive wastewater will still meet standards. Automation: Through automatic pump control, this equipment can automatically process radionuclide I... 131The automated adsorption process, from the decay cell to the ground, offers advantages in automation. Safety: The adsorption column is encased in a 4mm thick lead plate, effectively protecting the enriched I₂. 131 It does not affect people in the surrounding environment; the operation of enriching solid iodine waste is simple: enriching I 131 After decay, the samples can be placed directly in the device and transferred to ordinary medical waste disposal after decay is complete. No moving is required during this process, eliminating the need for additional space for placement and monitoring. Convenience: Real-time monitoring of iodine radiation levels inside and outside the adsorption column. Expanding the device allows for data interconnection, facilitating data acquisition and unified management and monitoring by radiation authorities. It eliminates the need for on-site wastewater collection and third-party testing, offering convenience and safety advantages for radiation monitoring personnel. Economy: This device significantly saves space in underground decay pools, resulting in substantial economic advantages and reducing space and maintenance costs.
