| Abstract: | The paper describes a removal process for hydrogen sulfide in a packed bed of the immobilized microorganism beads.The activated microorganisms,come from the S2- enrichment culture and training sewage sludge,are immobilized in calcium alginate beads.The experimental results in the packed trickling column show that the appropriate pH value and spray ratio of H2S removal are between 1.8 and 4.0 and more than 0.17m3/(m3·d) respectively.The maximum effective volume load of H2S (removal efficiency>96%) is in the range from 6000 to 6500 g/(m3·d).When the running load is higher than the maximum effective volume load,the gas flow resistance through the packed trickling column will increase and the H2S removal efficiency will decrease.The above mentioned malfunction running condition can be recovered by a back washing and low running load(<2000g/(m3·d)) process,the recovery period is 4 days.After stopping gas flow containing hydrogen sulfide for 12 hours and start up again,the period of the system removal efficiency recovery is less than 26 hours. |
