A lead screw 6 is rotatably arranged at the lower end of the cross beam 4. The mounting bracket 5 is threadedly connected to the lead screw 6.

[0018] A bevel gear ring 7 coaxial with the rotating shaft 3 is fixedly arranged on the support 2. A bevel gear 8 meshing with the bevel gear ring 7 is arranged at the end of the lead screw 6. During the rotation of the rotating shaft 3, the bevel gear ring 7 meshes with the bevel gear 8 to drive the bevel gear 8 to rotate, and the lead screw 6 rotates to drive the mounting bracket 5 to move on the cross beam 4. A medicine feeding unit is arranged on the mounting bracket 5. As the cross beam 4 rotates, the medicine feeding unit evenly spreads the liquid medicine over the surface of the sewage tank 1.

[0019] Embodiment 2: A chemical dosing device for sewage treatment is arranged above the sewage tank 1 and includes a support 2.
