1, infectious waste
Including infected gauze, bandages, gloves, syringes, needles, infusion sets, etc. These wastes may carry pathogens and need special treatment to prevent the spread of infection.
2. Chemical waste
Including expired or abandoned drugs, chemical reagents, fluorescent tubes, batteries, waste solvents, etc. These wastes may contain harmful substances or chemicals and need special treatment and disposal.
Step 3 cut waste
Including surgical blades, needles, sharp glassware, etc. These wastes may cause stab wounds or injuries to people and need to be safely packaged and disposed of.
4. Traditional waste
Including general garbage generated in general medical environment, such as paper, plastic, food residue, gauze, etc. These wastes can be treated by traditional garbage sorting.
5, special waste
Including radioactive substances, pathological wastes (such as tissue samples) and biomedical wastes (such as human organs, placenta, etc.). These wastes need special treatment and disposal to prevent harm to the environment and human health.
Medical waste treatment technology;
1, sterilization and disinfection method
There are many methods of sterilization and disinfection, such as high temperature and high pressure steam sterilization, chemical disinfection and microwave disinfection. Sterilization and disinfection methods mainly destroy the living environment of microorganisms and viruses and reduce the harm of medical waste to the environment through high temperature, high pressure, chemical reagents and microwave with a certain frequency or wavelength.
Sterilization and disinfection methods need to choose different sterilization methods for different medical wastes, and its sterilization effect is limited by many factors. Because of the variety and great difference of medical wastes, the best sterilization effect may not be achieved.
2, high temperature incineration method
According to research, 92% of the total weight of medical waste is combustible, and only 8% is nonflammable, which can be completely burned into ashes at a certain temperature and with enough oxygen. Incineration is a chemical process of deep oxidation. Under the action of high temperature flame, medical waste is transformed into residue and gas in incineration equipment through three stages: drying, ignition and incineration. Pathogenic microorganisms and harmful substances are also effectively destroyed due to the high temperature during incineration, and volume reduction and weight reduction can be effectively realized.
