Background technology
At present, in pharmacy, chemical industry, agricultural chemicals, rubber, food, garbage loading embeading, garbage transfer station, sewage treatment plant, livestock-raising Deng Gong enterprise field, all can produce poisonous and harmful or foul gas more or less, so air cleaning, peculiar smell control and deodorizing etc. are extremely important.
Foul gas pollutes and refers to that all stimulate olfactory organ cause that people are unhappy and damage healthy gaseous matter, that a kind of typical environmental hazard is generally acknowledged by countries in the world, many developed countries are studied it as a kind of single-row public hazards, and control is implemented in special legislation.In the industrial circle of Japan and more developed country, adopt the technology such as fixed-bed type charcoal absorption deodorization existing certain historical; In recent years, China also pays much attention to the monitoring of stench and control, discharge standard (GB14554-93) and the supporting analytical method of part malodorous compound have been worked out, one of prevention target of odor pollution will reach the odorant discharge standard of GB14554-93 regulation exactly, final purpose is to eliminate stench, creates work, the living environment of an odorless.
A kind of odor strength of odorant is strengthened along with increasing of trial, according to data, show, stench is to odorant, the contrast number of the quantity of stimulus of people's sense of smell to be directly proportional to people's sensation amount (being stench intensity), relation meets Weber-Fechner law between the two, and this law equation is shown below:
I=KlgC+a
In above formula: I: the sensation amount of people to sense of smell, odor strength; K: constant, odorant is different, and K value is different; C: malodorant concentration; A: constant, odorant is different, and a value is different.Known according to this law: even odorant is removed to 90%, people's odor concentration that sense of smell is felt has but only reduced less than 50%.This has determined that control stench is more difficult than other atmosphere pollutions of control, eliminate stench, than reaching also strict tens times to thousands of times of discharge standards, therefore strengthens odor pollution improvement and seems particularly important.The common foul gas removed in each field is as shown in the table.
