Background technology
Foul gas is using air as propagation medium, by the respiratory system of people to people as a kind of atmosphere pollution
Body has an impact, but it has the particularity of itself again.Using odor values as main contamination characteristics, i.e. the smelly threshold of foul gas is dense for it
Relatively low, the odorant concentration required after processing in gas lower even zero is spent, this allows for the improvement difference of odor pollution
In the improvement of general air pollution.
The main method that tradition administers foul waste gas has Physical, chemical method and bioanalysis three major types：
(1) Physical：Physical does not change the chemical property of odorant, simply with a kind of material by stink masking and it is dilute
Release, or odorant is transferred to liquid phase or solid phase by gas phase.Conventional method has masking method, dilution method, condensation method and mistake
Filter absorption method etc..
(2) chemical method：Chemical method is to be chemically reacted using another material with odorant, changes odorant
Chemical constitution, be allowed to be changed into the relatively low material of odorless material or stink, common method has combustion method, oxidizing process and chemistry
Absorption process (acid-base neutralization method) etc..
(3) biological deodorization method：Biological deodorization method refers to the metabolic activity degraded odorant using microorganism, is allowed to aoxidize
For final product.So as to reach odorlessization, innoxious purpose, conventional method has biological filter method, biosorption process (outstanding
