Definition and purpose of disinfection.
Disinfection refers to taking measures to eliminate or kill pathogens in the external environment and make them harmless. This is one of the important measures to prevent the spread of infectious diseases, aiming at cutting off the transmission route of pathogens and preventing the spread or spread of infectious diseases.
2, the method of disinfection
In order to achieve the purpose of disinfection, different methods can be used. Commonly used disinfection methods include physical disinfection, chemical disinfection and biological disinfection. Physical disinfection methods include heating, ultraviolet irradiation and radiation treatment. The rule of chemical disinfection is to use chemicals for disinfection; The rule of biological disinfection is to disinfect with biological antagonists.
3, the scope of application of disinfection
Disinfection can be applied to various fields, such as medical treatment, food and environment. In the medical field, disinfection is one of the important measures to prevent hospital infection; In the field of food, disinfection is an important means to ensure food safety; In the field of environment, disinfection is an important link to prevent the spread of infectious diseases.
4. Evaluation of disinfection effect
In order to evaluate the disinfection effect, scientific detection and evaluation are needed. Commonly used detection indicators include disinfectant residue, microbial killing rate, changes in living environment and so on. Through the detection and analysis of these indicators, we can understand the feasibility and effect of disinfection methods, and provide basis for further optimization of disinfection schemes.
5. Future development of disinfection
With the continuous progress of science and technology, disinfection technology is also developing. New disinfection technologies will continue to emerge in the future, such as low-temperature plasma disinfection and photocatalyst disinfection. These new technologies have higher efficiency and better environmental protection performance, and will be widely used in various fields.
At the same time, the research and application of disinfection technology will pay more attention to safety and humanization, and provide better support for ensuring human health and safety.
Selection and use of disinfectants
1, choice of disinfectant
When selecting disinfectants, many factors need to be considered, such as the activity, bactericidal spectrum, toxicity, residue and environmental friendliness of disinfectants. According to different application scenarios and requirements, different types of disinfectants can be selected, such as alcohols, aldehydes, acids, alkalis, halogens and phenols.
2, the use of disinfectant
You need to follow the instructions in the manual when using disinfectant. First of all, mix the disinfectant and water in proportion and shake well. Then wipe or soak the items with disinfectant, and rinse them with clean water after a certain period of time. When using disinfectants, you need to pay attention to safety and avoid inhalation and contact with the skin.
3. Precautions for preparation and use of disinfectants
Some matters needing attention when preparing and using disinfectants. First of all, it is necessary to avoid mixing disinfectants with other chemicals and avoid producing toxic substances. Secondly, when using disinfectants, you need to pay attention to personal safety and avoid inhalation and contact with the skin. In addition, we should also pay attention to the storage and transportation methods of disinfectants to avoid direct sunlight and high temperature.
