[0002] Medical domestic sewage mainly refers to the domestic sewage discharged by hospital administrative management and medical staff, as well as the drainage of canteens, single dormitories, and family dormitories; the existing technology for treating medical domestic sewage mainly uses ultraviolet lamp irradiation, ozone, and disinfectants for disinfection treatment. However, due to the turbidity of the sewage and poor light transmittance, the disinfection effect inside and at the bottom of the sewage will be affected; during the disinfection process using ozone and disinfectants, the sewage is not evenly mixed with ozone and disinfectants, thus affecting the sewage disinfection effect.

[0003] After retrieval, the prior art publication number CN221917463U discloses a disinfection device for sewage treatment, including a treatment tank and a lifting mechanism. A filtering mechanism is provided at the top of the lifting mechanism. A receiving bin is connected to the outer side surface of the treatment tank and is located directly above the filtering mechanism. The receiving bin is provided with openings at both the upper and lower ends. The filtering mechanism is in contact with the lower end of the receiving bin to block the bottom opening of the receiving bin. A stirring mechanism and a medicine bin are provided at the top of the treatment tank. A drain pipe is connected to the lower end of the outer side surface of the treatment tank, and a control valve is provided between the drain pipe and the treatment tank; its treatment process has the following disadvantages: the stirring mechanism stirs the wastewater with added medicine in the box, but the rotating rod and the stirring rod can only stir in the same direction, resulting in uneven mixing of the medicine in the upper layer of sewage and the lower layer of sewage, further causing incomplete sewage disinfection and waste of disinfection medicine.

[0004] After retrieval, the prior art publication number CN221235291U discloses a sewage treatment device with a disinfection function, which relates to the technical field of sewage treatment and includes a precipitation device. One end of the precipitation device is fixedly connected to a disinfection device, and the top of the disinfection device is fixedly connected to a stirring device. The precipitation device includes a precipitation tank, a grid plate is fixedly connected inside the precipitation tank, a diversion plate is fixedly connected inside the precipitation tank, and ash leakage holes are formed on the surface of the diversion plate; its treatment process has the following disadvantages: the disinfection lamp is fixed on the top of the disinfection tank, but due to the turbidity of the sewage and poor light transmittance, the sewage inside cannot be completely illuminated by the disinfection lamp, thus affecting the disinfection effect inside and at the bottom of the sewage. Summary of the Invention

[0005] The purpose of the present utility model is to overcome the deficiencies in the prior art and provide a medical domestic sewage purification and disinfection treatment device. The disinfection and water purification mechanism, stirring mechanism, and mixing mechanism cooperate to stir and mix sewage and disinfectant, so that the sewage can be fully disinfected.
