[0025] Adsorption bin 1: Its rear end is communicated with the upper end of the degradation bin 2 through the first connecting pipe 5. The upper end of the degradation bin 2 is provided with a feed pipe. The rear end of the degradation bin 2 is communicated with the upper end of the sedimentation bin 3 through the second connecting pipe 6. The inner wall of the adsorption bin 1 is fixedly connected with evenly distributed mounting plates. Ion bins 17 are placed on the upper ends of the four mounting plates at the lower end. The upper end of the adsorption bin 1 is connected with a bin cover 8 through evenly distributed bolts. The upper end of the bin cover 8 is provided with a water inlet pipe 9. The right side of the degradation bin 2 is provided with a control box 14. The inside of the control box 14 is provided with a control switch group 15.

The lower ends of the adsorption bin 1, the degradation bin 2, and the sedimentation bin 3 are all fixedly connected with evenly distributed support legs 16;

[0026] Stirring mechanism 4: It is arranged inside the degradation bin 2. The stirring mechanism 4 includes a motor 41, a rotating plate 42, a driving handle 43, an internal gear ring 44, a gear 45, and a rotating column 46. The motor 41 is arranged at the upper end of the degradation bin 2. The lower end of the output shaft of the motor 41 is fixedly connected to the driving handle 43. One end of the driving handle 43 away from the center of the degradation bin 2 is fixedly connected to a connecting shaft. The lower end of the connecting shaft is rotatably connected to the rotating plate 42. Three rotating columns 46 are rotatably connected inside the rotating plate 42. The upper ends of the rotating columns 46 are all fixedly connected to gears 45. The upper end of the inner wall of the degradation bin 2 is fixedly connected to an internal gear ring 44. The gears 45 are all meshed with the internal gear ring 44. The lower ends of the rotating columns 46 are fixedly connected to spiral blades. The input end of the motor 41 is electrically connected to the output end of the control switch group 15. Biological reagents are added into the degradation bin 2 through the feed pipe, thereby realizing the secondary treatment of heavy metal ions in the sewage. At the same time, the motor 41 is operated through the control switch group 15. The rotation of the output shaft of the motor 41 drives the driving handle 43 to rotate. The driving handle 43 makes the rotating plate 42 rotate around the central axis of the output shaft of the motor 41 through the connecting shaft. The rotation of the rotating plate 42 drives the three rotating columns 46 to rotate around the central axis of the output shaft of the motor 41. While the rotating columns 46 are rotating, the gears 45 all rotate on their own under the meshing action of the internal gear ring 44. The self-rotation of the gears 45 all drives the vertically adjacent rotating columns 46 to rotate on their own. The self-rotation of the rotating columns 46 all drives the rotation of the vertically adjacent spiral blades, thereby realizing the efficient stirring and mixing of the biological reagents and the sewage after ion adsorption, and further realizing the secondary degradation treatment of the residual heavy metal ions in the sewage;

[0027] Among them: Uniformly distributed upper diversion hoppers 11 are fixedly connected inside the sedimentation bin 3. Lower diversion hoppers 12 are fixedly connected between the upper diversion hoppers 11. A filter plate 7 is arranged at the upper end of the uppermost mounting plate. A handle is fixedly connected to the upper end of the filter plate 7;

[0028] Among them: Water pumps 10 are arranged at the lower ends of the first connecting pipe 5 and the second connecting pipe 6. The input ends of the water pumps 10 are electrically connected to the output end of the control switch group 15. A water outlet pipe is arranged at the lower end of the sedimentation bin 3. An electric valve 13 is arranged in the middle of the water outlet pipe. The input end of the electric valve 13 is electrically connected to the output end of the control switch group 15.

[0029] The working principle of a device for removing heavy metal ions from sewage provided by the present utility model is as follows: During operation, personnel stably place the adsorption chamber 1, degradation chamber 2, and other mechanisms on a horizontal working area through the support legs 16. After stable placement, personnel inject sewage into the interior of the adsorption chamber 1 through the water inlet pipe 9. The sewage first passes through the filter plate 7 for impurity removal, and then contacts the resin inside the ion chamber 17 to adsorb heavy metal ions in the sewage. At the same time, the control switch group 15 is used to operate the water pump 10 at the front side. The water pump 10 at the front side pumps the sewage inside the adsorption chamber 1 into the interior of the degradation chamber 2 through the first connecting pipe 5. Then, personnel add biological reagents into the interior of the degradation chamber 2 through the feed pipe, thereby realizing the secondary treatment of heavy metal ions in the sewage. At the same time, personnel use the control switch group 15 to operate the motor 41. The output shaft of the motor 41 rotates to drive the driving handle 43 to rotate. The driving handle 43 causes the rotating plate 42 to rotate around the central axis of the output shaft of the motor 41 through the connecting shaft. The rotation of the rotating plate 42 drives the three rotating columns 46 to rotate around the central axis of the output shaft of the motor 41. While the rotating columns 46 are rotating, the gears 45 all rotate self - driven under the meshing action of the internal gear ring 44. The self - rotation of the gears 45 all drives the vertically adjacent rotating columns 46 to rotate self - driven. The self - rotation of the rotating columns 46 all drives the rotation of the vertically adjacent spiral blades, thereby realizing the efficient stirring and mixing of the biological reagents and the sewage after ion adsorption, and further realizing the secondary degradation treatment of the residual heavy metal ions in the sewage. At the same time, personnel use the control switch group 15 to operate the water pump 10 at the rear side. The water pump 10 at the rear side pumps the sewage inside the degradation chamber 2 into the interior of the sedimentation chamber 3 through the second connecting pipe 6. Under the action of the evenly distributed upper diversion hopper 11 and lower diversion hopper 12, the sewage slowly descends, thereby facilitating the sedimentation of the sewage. Then, personnel use the control switch group 15 to operate the electric valve 13, and the sewage after removing heavy metal ions enters the next working area.

[0030] It should be noted that in the above - mentioned embodiments, the motor 41 disclosed can be a YE3 - 225M - 4P 45KW three - phase asynchronous motor, the water pump 10 can be an IHG vertical pipeline centrifugal pump, the electric valve 13 can be a JG90 - D3 - DQ - MF7 electric butterfly valve, and the control switch group 15 is provided with control buttons corresponding to the motor 41, water pump 10, and electric valve 13 one - to - one to control their switches.
