[0002] Wastewater treatment refers to the process of removing pollutants from sewage (including domestic sewage, industrial wastewater, rainwater runoff, etc.) through a series of physical, chemical or biological processes to purify the water quality and meet discharge standards or reuse water quality requirements. This process aims to reduce water pollution, protect water resources and achieve sustainable use of water resources.

[0003] In the process of sewage treatment, some mixed reagents are needed to assist in the treatment. When different reagents are needed, they often need to be pre-mixed. Usually, the pre-mixing is done separately, which makes the mixing time of the reagents longer and the separate mixing is more cumbersome and complicated, thus affecting the efficiency of sewage treatment. Summary of the Invention

[0008] Furthermore, the radius of the filter plate is the same as the radius of the interior of the dosing device body, and the cylinder is located above the bottom end of the pre-mixing bin.

[0009] Furthermore, a through hole is opened in the middle of the filter plate, and the radius of the through hole is larger than the radius of the first transmission rod.

[0010] Furthermore, the sealing block has the same radius as that of the pre-mixing bin, and a sealing rubber is provided at the joint between the sealing block and the cylinder.

This solves the problem that when different medicines are needed, it is often necessary to pre-mix these medicines. Usually, the pre-mixing is mixed separately, which makes the mixing time of the medicines longer and the separate mixing is more cumbersome and complicated, thereby affecting the efficiency of sewage treatment.

[0014] 2. In the utility model, the bottom end of the dosing device body is connected to the guide pipe, so that the medicine inside the dosing device body flows out through the guide pipe.

The sealing block 11 is slidably connected to the bottom of the pre-mixing bin 2, so that different medicines can be pre-mixed through the pre-mixing bin 2.

[0023] Specifically, the radius of the filter plate 10 is the same as the radius inside the dosing device body 1, the cylinder 12 is located above the bottom end of the pre-mixing bin 2, a through hole is opened in the middle of the filter plate 10, and the radius of the through hole is greater than the radius of the first transmission rod 6, the sealing block 11 is the same as the radius of the pre-mixing bin 2, and a sealing rubber is provided at the joint between the sealing block 11 and the cylinder 12 to prevent the medicine inside the pre-mixing bin 2 from flowing out.
