What is good for environmental sanitation disinfection?

1. Phenolic compounds, such as Lysol and Cointreau (compound phenol), have a good effect on eliminating bacterial and viral infections. Ultra-low temperature is reasonable, but it is corrosive, which is common in disinfection and sterilization of empty houses.

2. The common volatile alkylating agents are formalin solution (40% indoor formaldehyde), chlorpyrifos (glutaraldehyde-decylamine aqueous solution), ethylene oxide, etc., which have good sterilization ability, the ability to eliminate germs, spores, virus infections and molds, have certain toxic and side effects and irritation, and are often used for disinfection and sterilization of empty houses and equipment. Indoor formaldehyde and potassium permanganate commonly used in production fumigate empty houses. Indoor formaldehyde cannot be used for medicine if it is left for a long time or the soluble polyester chips below 9 are precipitated. Adding 10% ~ 12% ethanol can avoid polymer transformation of indoor formaldehyde.

3. Alkalis include caustic soda, quicklime powder, plant ash water, etc., which have a strong effect on eliminating virus infection and germs. The key is to disinfect the soles of feet, pigsty, places, cars and articles, and anthrax can also be disinfected with 5% caustic soda water solution.

4. Acids include lactic acid bacteria, glacial acetic acid, etc., which have low toxic and side effects and weak sterilization ability. Steam is often used as gas for disinfection and sterilization.
