Description
Technical field
The present invention relates to processing method and device to the foul gas deodorize.
Background technology
Stench is meant that gaseous material passes through a kind of psychological unplessantness displeasure or the detest sense of people's olfactory sensation generation, and odor pollution is a kind of sensation public hazards, has become one of seven overall situation public hazards in the world.Along with socioeconomic continuous development, rubbish stench problem becomes increasingly conspicuous, and seriously disturbs people's orthobiosis, and harm people's health.Along with the raising of people to environmental quality requirement, odor pollution is administered and is seemed more and more urgent.The method of conventional process foul gas is physics, chemical method, mainly contains methods such as soda acid absorption, chemisorbed, catalytic combustion.These method cost of investment height, equipment is various, complex process, energy consumption is big.For this reason, people begin one's study with the method for biofiltration deodorize, but the most deodorization efficiency of disclosed at present biological deodorization method is low excessively, and complex process fails to reach industrial requirement of actual application.
Summary of the invention
It is simple to the objective of the invention is to propose a kind of process equipment, and operating cost is low, can make the foul gas deodorize make it to reach the biologic deodorization method and the application apparatus thereof of discharge standard rapidly.
The present invention is the method for a kind of applying biological Filtration to the foul gas deodorize, it is characterized in that making and wait to remove odour by a kind of biofilter material, this gas is contacted with biofilter material filter back one-tenth Purge gas discharge, said biofilter material is the filler that a kind of inoculation has microorganism, said filler is the mixture of corrosion resistant Plant fiber thing or porous materials or corrosion resistant Plant fiber thing and porous materials, these materials mainly have following effect: the absorption microorganism, as microbe carrier, nutrient is provided for the microorganism of being inoculated.The microorganism of being inoculated in the filler is yeast and antibacterial, said yeast is mycocandida (Candida) yeast, Geotrichum (Geotrichum) yeast, Hansenula (Hansenula) yeast, pichia (Pichia) yeast, a kind of in Saccharomyces (Saccharomyces) yeast and Schizosaccharomyces (Schizosaccharomyces) yeast or several, said antibacterial is Nitrobacter (Nitrobacter) antibacterial, Bacillus cercus (Bacillus cereus), Bacillus licheniformis (Bacillus licheriformis), bacillus megaterium (Bacillus megaterium), Bacillus pumilus (Bacillus pumilus), bacillus subtilis (Bacillus subtilis), a kind of in pseudomonas fluorescens (Pseudomonas fluorescens) and the crooked pseudomonas (Pseudomonas geniculata) or several.
On the basis of inoculation mentioned microorganism, adding inoculation has Nocardia (Nocardia) actinomycetes or streptomyces microflavus (streptomyces microflavus), better effects if in the said filler.
Said corrosion resistant Plant fiber thing can adopt one or more mixture of dried bark, mushroom mud, coconut fibre and wood flour.
Said porous materials can adopt haydite or perlite.
Can attach loam in the said filler,, also contain the required nutrient of microorganism in the loam simultaneously to improve the ability of absorption microorganism.But the loam in the filler, its content is advisable to be not more than 30% of filler gross weight.
In filler,, also can but only plant with list to contain corrosion resistant Plant fiber thing and porous materials simultaneously for well.
Said biofilter material, its water content should be controlled at 20～50% scopes.Can be by reaching to regular shower water of filler or microbial culture medium.The spray microbial culture medium also can replenish necessary nutrient to filler.
When only adopting porous materials, then need regularly to spray culture of microorganism and keep and replenish necessary nutrient to filler as filler.
For obtaining deodorising effect preferably, need to regulate the flow that flows through said biofilter material, make the biofilter material surface loading be not more than 560m
