It is attached.Chemisorbed be using chemical reagent oxidize the formaldehyde into carbon dioxide and water or using amino as main active function groups with
Formaldehyde reacts to absorb formaldehyde.Physical absorption is by the larger specific surface area of adsorbent in itself, is had certain
Since formaldehyde molecule has certain memory, first is adsorbed using the charge or Van der Waals force of adsorbent for adsorption site
Aldehyde.But physical absorption is a reversible process, under certain condition, adsorbent can be desorbed formaldehyde.
Active carbon particle attracts each other by the Van der Waals force between formaldehyde molecule and activated carbon, first will as basis material
Formaldehyde absorbing is on its surface.
Chitosan is the deacetylated product of chitin, has macromolecular backbone, after being dissolved in acid solution, amino carries
Positive charge greatly strengthens the polarity of its own, and which increase the possibilities of its physical absorption formaldehyde.
Macromolecule organic amine polymer, polyhydric alcohol polymer have a large amount of amido functional group and a small amount of hydroxyl luminous energy
Group, amido functional group can rapidly be reacted with formaldehyde gas, and hydroxyl can enhance the moisture pick-up properties of adsorbent surface, in adsorbent surface
Water membrane is formed, quickening reaction speed improves purification efficiency in adsorbent surface absorption, enrichment so as to promote formaldehyde.
By activated carbon, chitosan, macromolecule organic amine polymer, polyhydric alcohol polymer it is compound after, it is larger by activated carbon
Surface area, the backbone of chitosan, hydroxyl moisture pick-up properties one work formaldehyde adsorption, then pass through amido functional group and formaldehyde
It is reacted, so as to avoid in formaldehyde emissions to air.
It further limits, by weight percentage, the content of the active carbon particle is 20%-50%, and the chitosan is
20%-30%, the macromolecule organic amine polymer are 30%-50%, and the polyalcohol is 1%-5%.
It further limits, the macromolecule organic amine polymer is polyethylene polyamine polymer.
It further limits, the polyalcohol is polyethylene glycol.
The present invention compared with prior art, can with PARA FORMALDEHYDE PRILLS(91,95) waste water carry out continuous processing, while it is small, at low cost, except first
Aldehyde effect is good, environmentally friendly.
