At present, in order to prevent and control the epidemic, various places are carrying out high-frequency disinfection, but the disadvantages of using traditional disinfectants are gradually emerging. Most disinfectants have certain toxicity and irritation. After disinfection, some toxic and carcinogenic disinfection by-products will be produced. Excessive disinfection will cause pollution to human health and the environment and water sources. It is reportedDuring the prevention and control of the epidemic, a number of abnormal deaths of wild animals caused by the abuse of disinfectants were monitored. Some degree of disinfectant contamination has been detected in underground drinking water in some places.

Hydrogen peroxide is a colorless and odorless transparent liquid. After the action is completed, it is decomposed into water and oxygen. It will not produce any other derivatives and disinfection by-products, and has an efficient killing effect on viruses, bacteria and fungi. It is an ideal environment-friendly ecological disinfectant. However, at present, domestic hydrogen peroxide products have great limitations, which limits their wide application: pure hydrogen peroxide is scarce and can only be used in the pharmaceutical industry and scientific research fields. At present, the level of domestic production technology is limited, and most of them produce extensive industrial hydrogen peroxide, which contains a certain amount of lead, arsenic, mercury and other heavy metals or some impurities. Many people's misunderstanding of hydrogen peroxide is because of industrial hydrogen peroxide.

Simple hydrogen peroxide is unstable, easy to decompose, affected by light, temperature and other factors, transportation, storage, etc. are very inconvenient, unsafe, and difficult to circulate commercially.

The actual disinfection effect has certain insufficiency. The simple hydrogen peroxide reaction is more intense, and the disinfection effect is interfered by organic substances, light, temperature and other factors.

Disinfection should not be abused excessively and without boundaries, and a scientific and reasonable disinfection system should be established, just like in waterworks and sewage treatment plants.,Disinfection with chlorine is strictly regulated for operation and protection,And the amount is also clearly defined. After disinfection, if the conditions allow, it should be washed again as far as possible to avoid the residue of harmful disinfectant. The waste liquid produced after disinfection should be treated innocuously and cannot be discharged directly or sprayed everywhere.With the expansion of the demand for hydrogen peroxide, factory production, hydrogen peroxide storage to prevent leakage, and the impact on personal safety caused by excessive disinfection in the living environment, it is necessary to do some preventive safety monitoring of hydrogen peroxide in the air.
