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 the 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 the intensive foul odour.Sucking H
2When S concentration is low, can see significantly hormesis, when inhaled concentration was higher, olifactory nerve tip paralysis can be to H
2The S stink disappears to continue and then goes into a coma, even dead.
The treatment process of tradition hydrogen sulfide not only costs an arm and a leg but also is prone to cause secondary pollution, facts have proved biological method purification atmospheric pollution Cheap highly effective.Wherein bio-trickling method purification odor pollution gas is a newer Environmental Biotechnology, also is the most promising at present waste gas biologic treating technique.
When process or behind pretreated waste gas entering bio-trickling Tower System; Through when the biomembranous packing layer; After repugnant substance in the gas is water-soluble, is recycled liquid again and, reaches the purpose of Purge gas attached to the absorption of the mikrobe on the filling surface, absorption, degraded.
Existing hydrogen sulfide biologic treating technique is often with on the active sludge direct inoculation filler, and the formation microbial film, the effective microbe ratio is low in the film, also need behind the extension film carry out the domestication of long period to it, and operational condition is controlled than difficult in the domestication process.Therefore need badly a kind of can be at bio-trickling filter rapidly and efficiently to H
2The bacterial strain that S gas is handled.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of and can remove H in the gas efficiently
2The citric acid bacillus of S gas.
Second purpose of the present invention provides a kind ofly can remove H in the 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 of S gas (Citrobacter sp.). 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 of S gas (Citrobacter sp.). sulfo-heterotrophic bacterium CGMCC No.5285 removes H in the gas
2The purposes of S gas.
Experimental result shows: with citric acid bacillus of the present invention (Citrobac ter sp.). after filling in bio-trickling filter after sulfo-heterotrophic bacterium CGMCC No.5285 is arranged on the ceramic grain filter, it can make bio-trickling filter can remove H fast
2S gas is handled back H
2S outgoing quality concentration is less than 0.03mg/m
3, reach the factory's circle primary standard among the GB14554-93 " odorant pollutant emission standard ".

Embodiment
Through specific embodiment the present invention is further described below.
Remove H in the gas
2The isolation cultivation method of the citric acid bacillus of S gas (Citrobacter sp.) sulfo-heterotrophic bacterium comprises the steps:
(1) mud is taken from Jizhuangzi Waste Water Treatment Plant, Tianjin, and supplement the nutrients every day liquid and aeration reach more than the 90mL/g SVI, accomplishes microorganism culturing.Stop to add nutritive medium, add sodium thiosulfate solution (sulfonium ion concentration is 2g/L) every day, keep ventilation, after 15 days wherein desulfurization bacterium become dominant bacteria, the desulfurization bacterium domestication is accomplished.
Nutritive medium is formed: glucose 0.1g, peptone 0.5g, K

-7The solution of concentration;
(3) choosing gradient is 10
-5～10
-7Bacteria suspension, get 1mL respectively and be inoculated in the substratum, each extent of dilution is done 3 parallel appearance, numbering; Under the condition of aerobic, preserve moisture for 10 ℃ and cultivated for 3 weeks;
(4) choosing colony is big in the culture medium flat plate from step (3); Single bacterium colony that form is different, line separates once more in the solid medium flat board, repeats plate streaking and separates; Make the homomorphosis of bacterium colony in microscope on the flat board; Single, big or small similar be single bacterium colony, called after sulfo-heterotrophic bacterium.
