The study on biologigal removes H2S in simulation yellow phosphorus tail gas

A dominant desulfurization bacterium, which were found from anaerobic pond of city sewage treatment plant by inductive domestication with in simulation yellow phosphorus tai gas which mixed with H₂S and CO, can fit anaerobic environment full of CO and have good removal capacity of H₂S in the anaerobic environment full of CO. The best temperature for remove H₂S in aqueous solution of the dominant desulfurization bacterium is about 23°C.It can removed H₂S which concentration during 22.14 -78.80 mg · L^-1.The maximal rate and efficiency for removing H₂S is 60% and 40 mg · L^-1 · h^-1. The dominant desulfurization bacterium can degrade aqueous solution which concentration from 46.28 mg · L^-1 to 10 mg · L^-1 below in 12h, it can almost degrade 100% H₂S in 24h. Experimental study on removing H₂S from simulation yellow phosphorus tail gas by domestication dominant desulfurization bacterium in bio-packing filtration tower has been carried out. When no H₂S could be detected at the outlet, the allowed maximum concentration of inlet reached 270 mg · m^-3; The H₂S removal efficiency above 90% when inlet load below 2.34 L · h^-1. The experimental study applied basis for desulfurization from yellow phosphorus tai gas through microbe.
