Medical wastewater is mainly discharged from medical treatment rooms, laboratories, wards, laundry rooms and operating rooms, etc. The source and composition of the wastewater are very complex. Hospital wastewater contains a large amount of pathogenic bacteria, viruses and chemical agents, such as drugs, disinfectants, diagnostic agents, detergents, and a large number of pathogenic microorganisms, parasite eggs and various viruses, such as roundworm eggs, hepatitis virus, tuberculosis bacteria and dysentery bacteria. It has the characteristics of spatial pollution, acute infection and latent infection. Compared with industrial wastewater and domestic wastewater, it has the characteristics of small water quantity and strong pollution. If it is discharged, it will seriously pollute the water source and spread diseases.

The isolation box is provided with a water pump, a controller and a power supply respectively. The water filter cage is arranged below the buoyancy mechanism. The isolation box is provided with a sprinkler on the top. The sprinkler is communicated with the water pump through a sprinkling pipe. The sprinkler is used to sprinkle water towards the purification pipe. The purification pipes are arranged uniformly around the buoyancy mechanism. The purification mechanism utilizes the buoyancy of the buoyancy mechanism to make the purification mechanism float on the surface of the wastewater. The water filter cage is immersed in the wastewater. At the same time, under the action of the sprinkler, the wastewater is sprinkled to the purification pipe to realize wastewater aeration, increase the oxygen content in the wastewater, and finally the wastewater is filtered and purified by the purification pipe to realize the filtration and purification treatment of medical wastewater.
