After the sewage enters the tank body, when there are too many impurities in the sewage or too much solid medicine is added, at this time, the reaction after stirring formed by sewage convection will be very slow and difficult. At this time, the mixing motor can be controlled to drive the rotating shaft to rotate, thereby driving the paddle to rotate, stirring the mixture of sewage and medicine, accelerating its reaction speed, and improving the mixing efficiency, thereby achieving flexible use and maintenance during use. At the same time, when the sewage is purified, when there are too many solid impurities in the sewage inside the tank body or too much solid medicine is added, it can also ensure that the sewage can be stably mixed and purified, and the purification efficiency is improved; Prior art 2 (application number CN202010356594.5, a Chinese patent published on August 25, 2020) A sewage treatment aeration device comprises a base, an upper end of the base is provided with an articulated shaft 1, a connecting rod is hinged on the articulated shaft 1, and a stirring box is fixedly connected to the end of the connecting rod, a bracket is provided on the base, a top plate is fixedly connected to the top of the bracket, a support rod is provided on the top plate, a motor 1 is fixedly connected to the end of the support rod, a shaft rod is fixedly connected to the output end of the motor 1, a disc is provided at the end of the shaft rod, an articulated shaft 2 is provided at the lower end of the disc, an articulated shaft 2 is hinged to a rotating rod, a through hole is provided on the top plate, the rotating rod passes through the through hole and an articulated shaft 3 is provided at the end, and the articulated shaft 3 is hinged on the top wall of the stirring box; by providing the rotating rod and starting the motor 1, the shaft rod can drive the disc to rotate, and then the rotating rod can drive the stirring box to shake, so as to stir the sewage in the stirring box, fully mix the sewage and oxygen, and improve the purification effect of the sewage.

[0004] Although current purification equipment can treat pollutants in wastewater by aeration, when treating wastewater, impurities or sediments in the wastewater will be mixed into the water body, which will affect its reaction effect and is not conducive to the mixing of subsequent reagents.
