Background

Formaldehyde is an organic chemical substance and is a colorless, irritant, toxic gas. Acute poisoning by formaldehyde manifests as irritation to the skin and mucous membranes. Inhalation of high concentrations of formaldehyde can lead to respiratory irritation symptoms, sneezing, coughing and associated nasal and throat burning sensations. In addition, bronchial asthma, pneumonia, and pulmonary edema can also be induced. A large amount of formaldehyde is taken into the digestive tract at one time, which can cause toxic symptoms of the digestive tract and the whole body, erosive burn of the oral cavity, the throat and the digestive tract, abdominal pain, convulsion, death and the like. The skin can cause allergic dermatitis, color spots, skin necrosis and other diseases when contacting with formaldehyde. Can kill the disease by orally ingesting 10-20 ml formaldehyde solution. Long-term exposure to formaldehyde can reduce respiratory function of organism, information integration function of nervous system and influence immune response of organism, and has toxic effect on cardiovascular system, endocrine system, digestive system, reproductive system and kidney. General symptoms include headache, weakness, anorexia, palpitation, insomnia, weight loss, autonomic nerve disorder, etc. Animal experiments also confirmed the pathological changes of the above related systems. And formaldehyde has strong carcinogenicity, namely, formaldehyde is put in a carcinogen list published by international cancer research institution of world health organization in 2017, 10 months and 27 days.

The largest decoration pollution in decoration is formaldehyde, and the excessive formaldehyde in a room is quite harmful to human bodies, so that a proper method must be adopted to reduce the content of the formaldehyde. The methods currently used for removing formaldehyde are roughly as follows: plant absorption method, aeration discharge method, carbon adsorption method, purifier treatment method, chemical agent treatment method, and light touch purification method. Chemical treatment captures formaldehyde mainly by two ways: one is to purify the air by neutralizing formaldehyde to produce harmless substances. One is to purify the air by blocking formaldehyde and organizing the volatilization of formaldehyde. The carbon adsorption method is to utilize the characteristics of activated carbon to adsorb and decompose formaldehyde.
