The nanocomposite adsorption materials have very good selective adsorption function for the main nuclides of radioactive wastewater. The polymer adsorbed with radionuclides forms a precipitate in the reactor under the action of the electromagnetic field, and the radionuclides enter the precipitate. The synthesis and adsorption of the adsorption material are carried out in the same container, making the device small in size and compact in structure. It is suitable for installation in a movable operation and treatment cabin or wastewater treatment vehicle.

[0047] Working principle: Before using this radioactive wastewater treatment equipment and treatment method, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figure 1 - Fig.11As shown, first, when distilling wastewater, water vapor will move upward and adhere to the condensation plate 127 inside the condensation box 103 for rapid condensation. The rotating motor 125 drives the rotating roller 126 and the condensation plate 127 to rotate, so that the condensed water falls on the top of the collecting plate 128. When the condensation plate 127 rotates to the top of the condensation box 103, the condensed water falls on the condensation plate 127 near the rotating roller 126.

8. A method for treating radioactive wastewater using a radioactive wastewater treatment device according to claim 7, characterized in that: The processing steps are as follows: Step 1: When distilling waste water, water vapor moves upward and adheres to the condensation plate (127) inside the condensation box (103) to be quickly condensed. The rotating motor (125) drives the rotating roller (126) and the condensation plate (127) to rotate, so that the condensed water falls on the top of the collection plate (128). When the condensation plate (127) rotates to the top of the condensation box (103), the condensed water falls on the condensation plate (127) near the rotating roller (126). The cleaning slide (129) inside the condensation plate (127) can drive the cleaning scraper (131) to move, so that the condensed water attached to one side of the condensation plate (127) can be discharged into the collection box (105) through the drain pipe (104). The conveying auger (136) is driven to rotate by the conveying motor (135), so that the chemical reagent inside the injection box (137) can be pushed into the sedimentation box (201); Step 2: The radioactive wastewater is distilled using the distillation dish (112) and the heater (124) at the bottom, so that the radioactive wastewater can be treated by distillation. When the radioactive wastewater is transported to the distillation dish (112) through the wastewater pipe (132), under the action of gravity, the distillation dish (112) drives the lifting and rotating rod (111) and the first lifting and sliding sleeve (109) to squeeze the first lifting and sliding spring (110), and at the same time, the lifting and rotating shaft (117) drives the second lifting and sliding sleeve (116) to squeeze the second lifting and sliding spring (118). When the wastewater fills the distillation dish (112), the distillation dish (112) contacts the tilting block (123). Under the action of the pushing spring (122) and the tilting block (123), the distillation dish (112) can be rotated, so that the radioactive wastewater is poured into the sedimentation box (201) at the bottom for sedimentation treatment. Step 3: Using the mixing motor (211) to drive the mixing main gear (212) to rotate, the rotating tripod (214) drives the second mixing spiral blade (217) to rotate. The structural characteristics of the second mixing spiral blade (217) can achieve up and down stirring of the radioactive wastewater and the chemical reagent. The meshing connection characteristics between the mixing main gear (212) and the mixing slave gear (213) can enable the mixing slave gear (213) to drive the rotating connecting shaft (215) and the first mixing spiral blade (216). The rotation of the first mixing spiral blade (216) can achieve secondary up and down stirring of the radioactive wastewater and the chemical reagent, thereby improving the stirring effect. The meshing connection characteristics between the mixing slave gear (213) and the meshing gear ring (208) can achieve the revolution of the first mixing spiral blade (216). Through horizontal rotation, the radioactive wastewater and the chemical reagent can be evenly mixed.
