Abstract—hydrogen sulfur was regarded as the research object in Packing can provide habitat and nutrient for
this study. Correlated research of biological treatment of anisms. Many kinds of packing materials can be used
hydrogen sulfide was investigated. Domestication in an aeration as carriers. Such as propylene rings,[1] ceramics,[2] lava rocks,[3]
flask was employed to screen out the optimal bacteria lava stones,[4] Polyvinyl difluoride cubes,[5] Ceramics has been
(Thiobacillus). Na2S was used as the inducer in the domestication used more popularly because of its’ large specific surface area
period. Gas-liquid phase joint inoculation method could start up (which can attach more biomass)
biotrickling filter effectively. The effect of air surface velocity
(– m3/h), the concentration of SO42- and S2- in the liquid, Many kinds of anisms can degrade pollutants in
empty bed residence time (EBRT) (150–11s) and the removal the waste air. For H2S pollution, it can be removal in both
capacity were investigated. The overall start-up period was only acidic and neutral surroundings by anisms.
