[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. There are many steps in sewage treatment. Based on the transformation of the components in the sewage, chemical agents need to be added to it so that it can react with the elements in the sewage and reduce the presence of harmful substances. At present, most of the dosing devices use dripping above the liquid level or fix the dosing pipe at the side of the treatment tank, and use pressurized injection. There are poor dissolution effects and low efficiency, which are limited by the position of the liquid surface.

[0003] According to the Chinese patent application number CN202022146982.9, a dosing device for sewage treatment is disclosed. When in use, the moving mechanism can drive the whole to move on the sewage pool, which can not only achieve precise dosing, but also complete the dosing during the movement process to ensure the dosing effect. The lifting mechanism can drive the depth of the dosing barrel in the sewage pool. Compared with the drip dosing method, it has the advantage of being fully mixed with the sewage and can give full play to the effect. By opening the valve and pump body of the medicine box, a certain amount of medicine can be added into the sewage. After the dosing is completed, the valve and pump body of the clean water tank are opened to clean the chemical raw materials remaining in the catheter and the dosing barrel to avoid residue.

[0004] However, the dosing device of the above scheme still has certain shortcomings during use: there is no structure for mixing and stirring the reagents inside the medicine box, and the reagents are prone to stand still when stored inside the medicine box, resulting in uneven mixing of the reagents, which in turn affects the treatment effect of the reagents on sewage to a certain extent.
