This type of waste mainly comes from the normal operation of nuclear power plants, equipment maintenance, accident handling and the decommissioning process of nuclear facilities. Low-level radioactive liquid waste contains not only radioactive nuclides, but also a large amount of organic substances, such as oils, surfactants, ethylenediaminetetraacetic acid (EDTA), picolinic acid, oxalic acid, citric acid, etc. The presence of these organic substances makes the treatment of waste liquid more complicated and difficult.

The first liquid inlet 102 and the first liquid outlet 103 are arranged at intervals 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 cavity 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 accommodating chamber 2011 inside. The upper and lower ends of the column body 201 have an inlet 2012 and an outlet 2013 respectively. The inlet 2012 and the outlet 2013 are both connected to the material accommodating 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 accommodating chamber 2011.

[0050] Specifically, the adsorbent 202 is made of 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 photocatalytic effect and decompose the organic pollutants in the cover page. The waste liquid after adsorption and photolysis flows to the outlet 2013 and is discharged out of the liquid outlet.

[0052] The material chamber 2011 is filled with an adsorbent 202.

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 thorough; the adsorption column 2 can be disassembled through the first opening 104, and extends in the up-down direction, 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.

[0053] Preferably, the main body 1 includes a shell 105 and a cover body 106, the first opening 104 is arranged on the upper end surface of the shell 105, the cover body 106 is detachably covered at the first opening 104 of the shell 105, the shell 105 and the cover body 106 are enclosed and defined to form a first accommodating cavity 101, and the first liquid inlet 102 is arranged on the cover body 106.

[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 , so that the user can check and clean them in time.

The adsorption column 2 is inserted into the second partition cylinder 402 from top to bottom through the second opening 4031. The partition plate 403, the first partition cylinder 401 and the mounting plate 302 jointly enclose and define a 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 from top to bottom into the second separation cylinder 402 through the second opening 4031, ensuring that the adsorption column 2 can be stably maintained in the correct position.

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 accommodating chamber 101 and the bottom of the partition plate 403 are covered with a reflective coating 6, which can effectively reflect the light emitted by the light column 301, so that the light is reflected multiple times in the accommodating chamber, thereby increasing the contact time between the waste liquid and the light source.
