Abstract:
Abstract The airlift reactor with an effective volume of 0.40 L was used to study the capability of removing H2S. The bacteria which were used to remove H2S were isolated and cultured in our lab. Under the conditions of 28 ℃ and initial pH 8, the effects of different gas flows and different H2S concentrations on the microbial desulfurization capacity and, efficiency of the reactor were investigated. The effects of H2S input load and gas flows on the forming rate of sulfate were also investigated. The results showed that the optimum gas flow was 0.2 L/min. Under this condition, when the input load of H2S was 5.76 kg m-3 d-1, the maximum elimination capacity was 5.62 kg m-3 d-1, while the removal efficiency could still maintain more than 97.8%. When the input load was 4.37~4.93 kg m-3 d-1, the removal efficiency of H2S could reach 99%, and the major product was sulfur. These data indicated that high recovery rate of sulfur can be acquired by increasing the input load of H2S or decreasing the gas flow. Fig 3, Tab 2, Ref 15
