Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a radioactive organic waste liquid treatment device and a waste liquid treatment system. Background Art

[0002] Low-level radioactive liquid waste is one of the major radioactive wastes generated during the lifecycle of nuclear facilities. Statistics show that low-level liquid radioactive waste accounts for over 95% of total radioactive waste, including significant amounts of radioactive organic waste. This waste primarily originates from normal nuclear power plant operations, equipment maintenance, accident response, and decommissioning. Low-level liquid radioactive waste contains not only radionuclides but also significant amounts of organic matter, such as oils, surfactants, ethylenediaminetetraacetate (EDTA), picolinic acid, oxalic acid, and citric acid. The presence of these organic compounds complicates and challenges waste treatment.

[0003] Organic matter and radioactive nuclides may interact with each other to form stable complexes, which makes the separation of radioactive nuclides more difficult, especially when treated by conventional ion exchange resins, which affects the removal of radioactive substances. In addition, these organic substances may also reduce the decontamination factor of subsequent treatment processes, increasing the cost and complexity of the treatment process. Most existing waste liquid treatment equipment relies on physical adsorption, chemical reactions or photocatalysis, but these methods are single and have weak synergistic treatment capabilities for organic matter and radioactive nuclides. Although adsorption technology can effectively remove some organic matter, its effectiveness is often limited when faced with organic waste liquid containing radioactive nuclides. Summary of the Invention

[0045] The technical solution of the present invention is further described below with reference to the embodiments and drawings.

[0046] like Figure 1-3 As shown, a first aspect of an embodiment of the present invention provides a radioactive organic waste liquid treatment device, comprising:

[0047] The main body 1 has a first accommodating chamber 101 therein, and has a first liquid inlet 102, a first liquid outlet 103, and a first opening 104. The first liquid inlet 102 and the first liquid outlet 103 are spaced apart in the vertical direction, and the first liquid inlet 102, the first liquid outlet 103, and the first opening 104 are all connected to the first accommodating chamber 101;

[0048] The adsorption column 2 is detachably accommodated in the first accommodating chamber 101 through the first opening 104 and extends in the up-down direction. The adsorption column 2 is arranged between the first liquid inlet 102 and the first liquid outlet 103. The adsorption column 2 includes a column body 201 and an adsorbent 202. The column body 201 has a material holding chamber 2011 inside. The upper and lower ends of the column body 201 respectively have an inlet 2012 and an outlet 2013. The inlet 2012 and the outlet 2013 are both connected to the material holding chamber 2011. The inlet 2012 is connected to the first liquid inlet 102, and the outlet 2013 is connected to the first liquid outlet 103. The adsorbent 202 is filled in the material holding chamber 2011.

[0049] The light source assembly 3 includes a light column 301 . The light column 301 is disposed in the first accommodating cavity 101 and extends in the up-down direction. The light column 301 is disposed on one side of the adsorption column 2 .

[0050] Specifically, the adsorbent 202 is titanium zirconium pyrophosphate.

[0051] Based on the above technical solution, the waste liquid flows from the first liquid inlet 102 to the inlet 2012 and enters the material chamber 2011. The adsorbent 202 in the adsorption column 2 effectively adsorbs the radioactive nuclides and organic pollutants in the waste liquid. At the same time, the light of the light column 301 irradiates the waste liquid in the adsorption column 2 to ensure the catalytic effect of light and decompose the organic pollutants in the cover page. The waste liquid after adsorption and photolysis flows to the outlet 2013 and flows out of the liquid outlet for discharge.

[0052] The material chamber 2011 is filled with an adsorbent 202. Through adsorption, the adsorption column 2 can prevent radioactive nuclides from forming stable complexes with organic matter, thereby improving the removal effect of radioactive substances in the waste liquid; the light column 301 is arranged in the first receiving chamber 101 and extends in the up and down directions, located on one side of the adsorption column 2, and the light source assembly 3 provides the necessary light energy to stimulate the photocatalytic reaction and promote the degradation of organic matter in the waste liquid. The light column 301 is arranged next to the adsorption column 2 to ensure that the light source can effectively irradiate the waste liquid in the adsorption column 2, thereby improving the photocatalytic effect and further decomposing the organic pollutants in the waste liquid; the synergistic effect of the two can improve the purification effect of the waste liquid, making the treatment process more efficient and more thorough; the adsorption column 2 can be disassembled through the first opening 104 and extends in the up and down directions, located in the first receiving chamber 101, which is convenient for the installation, maintenance, cleaning and replacement of the adsorption column 2 and the adsorbent 202.

[0054] Specifically, the cover 106 is hinged to the housing 105 through the first opening 104 .

[0055] The adsorption column 2 can be taken out from the first accommodating chamber 101 by simply opening the cover 106 , which makes it more convenient to replace the adsorption column 2 and the adsorbent 202 , allowing the user to conduct inspection and cleaning in a timely manner.

When viewed from above and below, the optical column 301 is disposed in the center of the first accommodating chamber 101, and the multiple adsorption columns 2 are circumferentially spaced apart around the optical column 301. The provision of multiple adsorption columns 2 allows for the simultaneous treatment of a larger volume of waste liquid, ensuring the throughput of the radioactive organic liquid waste treatment apparatus and preventing the difficulty in draining the waste liquid when a single adsorption column 2 fails or becomes clogged.

[0057] More preferably, the radioactive organic waste liquid treatment device further comprises a separation component 4, the separation component 4 comprises a first separation cylinder 401, a plurality of second separation cylinders 402 and a separation plate 403, the first separation cylinder 401 is arranged in the middle of the first accommodating chamber 101, and the plurality of second separation cylinders 402 are circumferentially spaced and arranged on the outer periphery of the first separation cylinder 401, the first separation cylinder 401 and the second separation cylinder 402 are both extended in the up-down direction, and the lower end of the first separation cylinder 401 passes downward through the lower end of the shell 105, and the lower end of the first separation cylinder 401 is provided with an outwardly extending mounting outer edge 4011, the light source component 3 comprises a mounting plate 302, and the light column 3 01 is arranged on the upper end surface of the mounting plate 302, and the mounting plate 302 can be detachably mounted on the mounting outer edge 4011. The partition plate 403 is arranged in the first accommodating cavity 101 and is connected to the upper end surface of the first separating cylinder 401. A plurality of second openings 4031 are provided on the partition plate 403, and the plurality of second openings 4031 are connected one-to-one with the plurality of second separating cylinders 402. The adsorption column 2 is inserted from top to bottom into the second separating cylinder 402 through the second opening 4031. The partition plate 403, the first separating cylinder 401 and the mounting plate 302 jointly enclose and define the second accommodating cavity 5, and the light column 301 is accommodated in the second accommodating cavity 5.

[0058] Specifically, the mounting plate 302 and the mounting outer edge 4011 are mounted by bolts using a flange structure.

[0059] The adsorption column 2 is inserted into the second separation cylinder 402 from top to bottom through the second opening 4031, ensuring that the adsorption column 2 can be stably maintained in the correct position. At the same time, this insertion method makes the replacement and maintenance of the adsorption column 2 easier and more intuitive, thereby improving the operability and maintenance convenience of the equipment; the separation plate 403, the first separation cylinder 401 and the mounting plate 302 together enclose a second accommodating chamber 5 for accommodating the light column 301, separating the light column 301 from the operating space of the adsorption column 2, and the maintenance area has independence, making the manually operated maintenance and replacement of the light column 301 safer, and will not directly contact radioactive substances, reducing the potential risk of radioactive exposure; and the mounting plate 302 and the mounting outer edge 4011 are installed by flange bolts, which is convenient and quick to operate.

[0060] More preferably, the partition assembly 4 also includes a plurality of first partition rods 404, a plurality of second partition rods 405, and a plurality of third partition rods 406, the two ends of the first partition rod 404 are respectively connected to the outer peripheral wall of the first partition cylinder 401 and the outer peripheral wall of the second partition cylinder 402, the two ends of the second partition rod 405 are respectively connected to the inner peripheral wall of the first accommodating cavity 101 and the outer peripheral wall of the second partition cylinder 402, the two ends of the third partition rod 406 are respectively connected to the outer peripheral walls of the two adjacent second partition cylinders 402, and the plurality of first partition rods 404, the plurality of second partition rods 405, and the plurality of third partition rods 406 are arranged at intervals in the up and down directions.

[0061] Multiple first, second and third partition rods 406 provide additional support for the connection between the first partition cylinder 401, the second partition cylinder 402 and the accommodating chamber, thereby enhancing the structural stability of the entire partition assembly 4. The bearing capacity of the entire partition assembly 4 is guaranteed, and when a large amount of waste liquid flows into the adsorption column 2, the waste liquid treatment process can still be kept stable; the first partition cylinder 401 and the second partition cylinder 402 are separated, and in the event that the second partition cylinder 402 ruptures in time, the waste liquid flowing out from the rupture of the second partition cylinder 402 will not enter the second accommodating chamber 5 area where the light column 301 is located, so as to avoid secondary contamination.

[0062] Specifically, the first partition cylinder 401 , the second partition cylinder 402 , the first partition support rod 404 , the second partition support rod 405 , and the third partition support rod 406 are all made of transparent materials.

[0064] The inner wall of the first chamber 101 and the bottom of the partition plate 403 are covered with a reflective coating 6, which effectively reflects the light emitted by the light column 301, causing the light to be reflected multiple times within the chamber, thereby increasing the contact time between the waste liquid and the light source. This significantly improves the efficiency of the photocatalytic reaction, allowing the photocatalyst to more fully degrade organic matter in the waste liquid, thereby enhancing the treatment effect.

[0067] The material holding cavity 2011 is filled with multiple refractive elements 7, such as polyhedral glass balls, which can effectively enhance the scattering and reflection of light in the cavity. The refractive elements 7 refract and reflect light, making the light more evenly distributed in the material holding cavity 2011, increasing the propagation path and action time of light in the cavity, increasing the contact area between the waste liquid and the light and the uniformity of the illumination, thereby improving the efficiency of the photocatalytic reaction.

[0068] A second aspect of an embodiment of the present invention provides a waste liquid treatment system, including a radioactive organic waste liquid treatment device, the waste liquid treatment system including:

[0069] The waste liquid tank 8 has a second liquid inlet 801 and a second liquid outlet 802, and the second liquid outlet 802 is connected to the first liquid inlet 102;

After the reaction is completed, it flows into the first liquid flow pipeline 10, and the organic matter concentration and conductivity in the waste liquid are measured by the COD meter 11 and the conductivity meter 12 respectively. If either of the above two data meets the treatment standard, the second switching valve 15 is opened, and the waste liquid in the first liquid flow pipeline 10 flows through the second liquid flow pipeline 14 back to the waste liquid tank 8, and then the adsorption and photocatalytic reaction are repeated.
