[0002] In the process of sewage treatment, since sewage contains a large number of harmful substances such as chemicals and bacteria, they all need to be disinfected, sterilized, and settled by chemical drugs. In this process, dosing equipment is needed. When the dosing sewage treatment device is in use, as the chemicals react in the sewage, a large amount of foam and floating objects often appear on the surface of the sewage. However, most of the existing dosing sewage treatment equipment does not have equipment to help remove foam and floating objects, so that foam and floating objects are on the surface of the sewage, preventing air, light, etc. from contacting the sewage, which is easy to affect the occurrence of some chemical reactions and affect the treatment of sewage.

[0003] To this end, a Chinese patent with patent number CN221253973U discloses a medicated sewage treatment device for sewage treatment, including a treatment tank body, a dosing component for adding chemicals into the treatment tank body is arranged on one side of the treatment tank body, a connecting pipe is arranged at one end of the treatment tank body, a derivation pipe is arranged on the side of the treatment tank body away from the connecting pipe, and a mounting frame is arranged at the end of the treatment tank body. The utility model adds chemicals to the sewage inside the treatment tank body through the dosing component. When foam and floating objects appear on the surface of the sewage inside the treatment tank body, the driving cylinder can be started to drive the storage box and the suction sleeve to move downward, so that the suction sleeve is attached to the sewage surface. At this time, the fan body is started to form suction under the suction sleeve, and the suction sleeve is used to absorb the foam and floating objects. The foam and floating objects stay in the storage box, which can quickly and effectively remove the foam and floating objects on the sewage surface.

[0004] However, the above device absorbs floating objects that are retained in the storage box and are not easy to be cleaned and discharged in time, which is time-consuming and labor-intensive. In addition, the dosing component is not conducive to accurate dosing of sewage and is prone to drug waste, which in turn easily affects the sewage treatment effect and work efficiency.
