Used to deal with medical waste has been a variety of technologies, according to the different principles of treatment, generally can be divided into sterilization and disinfection method, incineration, plasma method, pyrolysis and sanitary landfill method and so on.
Folding sterilization and disinfection method
Sterilization and disinfection treatment method is more, can be taken to high temperature and high pressure steam sterilization, chemical disinfection, microwave disinfection method. Sterilization and disinfection method is mainly through high temperature, high pressure, chemical reagents, a certain frequency or wavelength of microwave and other technologies, to destroy the living environment of microorganisms and viruses, to reduce the degree of medical waste on human health and environmental hazards. Sterilization and disinfection method needs to choose different sterilization methods for different medical wastes, and there are many limiting factors for its sterilization effect. Due to the wide variety of medical wastes and their great differences, it may not be possible to achieve the best sterilization effect. Moreover, the volume and appearance of the waste will not change significantly, and it can be used for pre-treatment before incineration under general conditions, and in some cases it can also be used as a means of treatment before final landfill disposal.
Folding high-temperature incineration method
According to the research, 92% of the total weight of the components in the medical waste is combustible, and the non-combustible components are only 8%, which can be completely burned into ashes at a certain temperature and under sufficient oxygen conditions. Incineration treatment is a deep oxidation chemical process, under the action of high temperature flame, incineration equipment within the medical waste through the drying, ignition, incineration of the three stages will be converted into residue and gas, pathogenic microorganisms and harmful substances in the incineration process is also due to the high temperature and the effective destruction of the incineration process, but also effectively realize the volume and weight reduction. Incineration is applicable to all kinds of infectious medical waste and is the mainstream technology in the field of medical waste treatment.
Folding pyrolysis treatment method
Pyrolysis is the process of utilizing the thermal instability of the organic matter in the garbage, heating the organic components of the medical garbage at high temperature in anaerobic or oxygen-poor conditions, and using the heat energy to make the compound's chemical bond break, so that the large molecular weight of the organic matter is transformed into combustible gases, liquid fuels, and coke. This treatment technology and incineration method compared with the lower temperature, no open flame combustion process, heavy metals and other heavy metals are mostly maintained in the residue, can recover a large amount of heat energy, a better solution to the biggest problem of medical waste incineration treatment technology.
Folding plasma method
Plasma method is an innovative technology to deal with medical waste, it disinfects and sterilizes the principle that: the high temperature generated by the plasma arc furnace kills all the microorganisms in the medical waste, destroys the toxic drugs and toxic chemicals remaining in the cells, and melts the metal sharps and inorganic chemicals to make them completely destroyed.
