The present invention discloses citrobacter sp. for removing H2S gas from gas, and a use thereof. The citrobacter sp. desulfurization heterotrophic bacteria CGMCC No.5285 for removing the H2S gas from the gas has the function of H2S gas removing from the gas. The experimental results show that: with arranging the citrobacter sp. desulfurization heterotrophic bacteria CGMCC No.5285 on a ceramsite filtering material, and filling the resulting material in a bio-trickling tower, the bio-trickling tower can rapidly remove the H2S gas, the mass concentration of the H2S on the H2S outlet is less than 0.03 mg/m<3> after treating so as to meet the factory boundary first class standard in the GB14554-93 emission standards for odor pollutants.
Description
Technical field
The present invention relates to remove H in gas
2the citric acid bacillus of S gas and purposes.
Background technology
H
2s has pungency and asphyxiant colourless gas, and lower concentration just has strong foul odour.Sucking H
2when S concentration is lower, can see obvious hormesis, when inhaled concentration is higher, olifactory nerve tip paralysis, can be to H
2s stink disappears to continue and goes into a coma, even dead.
The treatment process of tradition hydrogen sulfide is not only expensive but also easily cause secondary pollution, facts have proved biological method purification atmospheric pollution Cheap highly effective.Wherein to purify odor pollution gas be a newer Environmental Biotechnology to bio-trickling method, is also the most promising biological treatment technology for waste gas at present.
When through or enter after bio-trickling Tower System without pretreated waste gas, by when the biomembranous packing layer, after repugnant substance in gas is water-soluble, then is recycled liquid and is attached to microorganism adsorption, absorption, the degraded on filling surface, reaching the object of Purge gas.
Existing hydrogen sulfide biologic treating technique is directly inoculated active sludge on filler often, and forms microbial film, and in film, effective microbe ratio is low, also needs it to carry out the domestication of long period after biofilm, and the more difficult control of operational condition in domestication process.Therefore needing one badly can be at bio-trickling filter rapidly and efficiently to H
2the bacterial strain that S gas is processed.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide one can remove efficiently H in gas
2the citric acid bacillus of S gas.
Second object of the present invention is to provide one can remove H in gas efficiently
2the purposes of the citric acid bacillus of S gas.
Technical scheme of the present invention is summarized as follows:
H in a kind of removal gas
2the citric acid bacillus (Citrobacter sp.) of S gas. sulfo-heterotrophic bacterium CGMCC No.5285, it has H in the gas of removal
2the ability of S gas.
H in a kind of removal gas
2the citric acid bacillus (Citrobacter sp.) of S gas. sulfo-heterotrophic bacterium CGMCC No.5285 removes H in gas
2the purposes of S gas.
Experimental result shows: by citric acid bacillus of the present invention (Citrobac ter sp.). after sulfo-heterotrophic bacterium CGMCC No.5285 is arranged on ceramic grain filter, fill in after bio-trickling filter, it can make bio-trickling filter can remove fast H
2s gas, H after processing
2s outgoing quality concentration is less than 0.03mg/m
3, reach the factory's circle primary standard in GB14554-93 " emission standard for odor pollutants ".
Brief description of the drawings
Fig. 1 is that bio-trickling filter is processed containing H
