[0003] The principles of formaldehyde oxidation reaction mainly include ozone oxidation and chemical oxidation. Ozone oxidation is an effective formaldehyde treatment method. Ozone, as a strong oxidant, can undergo a redox reaction with formaldehyde, changing the molecular structure of formaldehyde and ultimately converting it into harmless substances such as water and carbon dioxide. The principle of this reaction is that ozone undergoes a redox reaction with the carbon and hydrogen atoms in formaldehyde, destroying the chemical bonds of formaldehyde and generating new substances. Chemical oxidation usually uses strong oxidants such as hydrogen peroxide and potassium permanganate to react with formaldehyde, converting it into carbon dioxide and water. These strong oxidants can react chemically with formaldehyde, destroying its molecular structure and generating harmless products.

[0004] Since formaldehyde generally exists as a gas, the contact time between formaldehyde and reaction gas is short during the ozone oxidation reaction in the oxidation reactor, resulting in incomplete reaction and thus affecting the effect of the formaldehyde oxidation reaction.
