[0024] Combined with attachment Figure 1-4 , a heavy metal treatment component is provided in the tank body 1; the heavy metal treatment component includes a cover body 8 provided on the tank body 1, and a water inlet 9 and a drug inlet 10 are respectively provided on the cover body 8 and near both ends; a drive motor 11 is provided on the cover body 8 and at the middle end, and the output end of the drive motor 11 extends into the tank body 1 and is provided with a rotating shaft 12, and the lower end of the rotating shaft 12 is rotatably connected to the tank body 1; a number of partition plates 13 are provided on the outside of the rotating shaft 12, and the partition plates 13 are all mesh plates, and a slot 14 is provided inside that passes through the upper end, and a magnetic piece 15 is slidingly provided in the slot 14, and the magnetic piece 15 is a magnet that can absorb iron ions in the wastewater; a vulcanizing machine or other reagent for heavy metal precipitation is added through the drug inlet 10, and then the partition plate 13 is rotated to perform turbulent flow and uniform mixing; it should be noted that a valve is provided at the lower end of the tank body 1, and the valve is in a closed state during the above operation to prevent wastewater from directly entering the tank body 2.

[0025] Combined with attachment Figure 3-5 The outside of the rotating shaft 12 is provided with several limiting grooves 16 that pass through the upper end. The cross-section of the limiting grooves 16 is T-shaped. The cross-section of the partition plate 13 close to the rotating shaft 12 is T-shaped, so that the partition plate 13 can be limited so that it will not fall out. At the same time, the above structure enables the number of partition plates 13 to be increased or decreased, and can also be taken out for replacement.

[0026] Combined with attachment Figure 3 、 6 A sediment separation component is provided in the tank body 2, and the sediment separation component includes a separation bin 17. A feed port 18 is provided at the upper end of one side of the separation bin 17, and the upper end of the feed port 18 is connected to the tank body 1; the lower end of the separation bin 17 near the feed port 18 is connected to a downwardly inclined guide pipe, and the lower end of the guide pipe is connected to a separation bin 2 19; a limit block 20 is provided on one side of the separation bin 17 and below the guide pipe, a grid plate 21 is provided in the separation bin 17 for rotating back and forth, and a water outlet pipe 22 is provided at the lower end of the separation bin 17, and the lower end of the water outlet pipe 22 extends to the lower end of the tank body 2, and a valve is provided at the lower end of the tank body 2; a grid plate 23 is rotatably provided in the separation bin 2 19, a discharge port 24 is provided on one side of the separation bin 2 19 and below the grid plate 23, and a branch pipe 25 connected to the water outlet pipe 22 is provided at the lower end of the separation bin 2 19.

[0027] In the above structure, after the wastewater passes through the heavy metal treatment component, sulfide precipitates or precipitates that respond to other added agents are formed, and then the solid-liquid mixture with the precipitate enters the separation bin 17 through the feed port 18. The liquid falls directly, and the solid accumulates on one end of the mesh plate 21. After reaching a certain weight, the mesh plate 21 tilts, so that the solid precipitate above passes through the guide pipe into the separation bin 2 19, and then is filtered again in the separation bin 2 19. Finally, the solid precipitate is discharged through the discharge port 24, and the liquid flows back to the outlet pipe 22 through the branch pipe 25, thereby completing the separation of the precipitate and removing the heavy metals in the wastewater.

[0028] The working principle of the present invention is as follows: by adding sulfide and other reagents for heavy metal precipitation into laboratory wastewater, the heavy metals in the wastewater are combined with the reagents to precipitate. In this process, the driving motor 11 drives the partition plate 13 to rotate through the rotating shaft 12 to facilitate auxiliary mixing and stirring, and the magnetic piece 15 in the partition plate 13 is a magnet, which can adsorb iron ions in the wastewater; then the precipitate is separated through the separation chamber one and the separation chamber two. During separation, the liquid falls directly through the grid plate 21 and the grid plate two 23, and the solid first enters the separation chamber two 19 along the guide pipe, and then is discharged through the discharge port 24. At the same time, the wastewater entrained in the solid entering the separation chamber two 19 can be filtered again under the action of the grid plate two 23, thereby improving the solid-liquid separation effect. After the above steps, the separation of heavy metal components in the wastewater can be achieved, thereby greatly reducing the hazards of laboratory wastewater and facilitating the next step of treatment.

[0029] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
