1, sterilization and disinfection method
Sterilization and disinfection treatment methods are more, can take 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 technology to destroy the living environment of microorganisms and viruses, reduce the degree of medical waste on human health and environmental hazards.
2, high-temperature incineration method
According to research, 92% of the total weight of medical waste components for the combustible components, non-combustible components of only 8%, at a certain temperature and sufficient oxygen conditions, can be completely burned into ashes.
3, pyrolysis treatment method
Pyrolysis is the use of waste in the thermal instability of organic matter, the organic components of the medical waste in the oxygen-free or oxygen-poor conditions of high temperature heating, heat energy to make compounds of the chemical bond breaking, so that large molecular weight of the organic matter into a combustible gas, liquid fuels, and the process of coke.
4, plasma method
Plasma method is an innovative technology to deal with medical waste, it disinfects and sterilizes the principle: the high temperature produced by the plasma arc furnace kills all the microorganisms in the medical waste, destroys the poisonous drugs and poisonous chemicals left in the cells, and melts the metal sharps and inorganic chemicals to make them completely destroyed.
5, electric arc furnace treatment technology
Electric arc furnace is heated by electric arc batch reactor, the combustion temperature of about 1650 ~ 3300 ℃, residence time of about 8 ~ 10 min. electric arc furnace electrode rods through the alternating current produces a strong magnetic stirring effect, waste and steel can be fully mixed, the waste in the case of high temperature cracking and oxidation of CO2 and H2O, thus infectious bacteria can be in a very short period of time. Thus, the infectious bacteria can be completely destroyed in a very short time.
6, irradiation technology
Irradiation treatment technology is the use of electron beams to kill microorganisms and bacteria. Ionizing radiation source (such as Co60) excited electrons and the molecular structure of the object of treatment of electronic interactions, the accumulated energy can destroy the chemical bond of organic compounds, thus the microorganisms to be cracked and destroyed.
7, liquid alloy treatment method
The technology is Sn, Bi and other special low-melting-point alloy heated to about 400 ℃, so that the alloy becomes liquid, and then put the medical waste into the liquid alloy metal, in the killing of bacteria and viruses at the same time can be realized in the evaporation of water, and volatile gases are heated to 800 ℃, which will be the complete combustion of volatile organic compounds Exhaust fumes.
Expanded:
With the development of China's economy, China's medical care has also made great progress, but as a result, a lot of problems have arisen, such as the disposal of medical waste.
Medical waste disposal, refers to the people concerned, the process of disposal of medical waste goods and garbage generated within the hospital with physical, chemical or biological infectious damage to humans or animals and the environment. It includes the process of proper sterilization and even complete removal of certain infectious medical waste items. Therefore, on June 16, 2003, the State Council issued the "Regulations on the Management of Medical Waste".
On March 15, 2019, the 2019 CCTV 3-15 Gala exposed used syringes and blood packets, which were crushed and turned into vegetable net bags and children's toys.
