摘要: 采用Bio-SR工艺，利用铁盐吸收与氧化亚铁硫杆菌的联合作用对H2S进行脱除实验。通过改进微生物的培养条件，减少了83.9%的沉淀量，一定程度上解决了挂膜后生物填料塔易堵塞的问题，保证了填料塔的连续运行。在实验选取工况下，硫化氢脱除率可达到98.4%以上，当吸收液中Fe3+浓度为5.5～6 g/L、H2S进气浓度为1 g/m3、通气量为0.08～0.12 m3/h时效果最佳，反应器可持续高效地运行。此外，对进气浓度、通气量与硫化氢去除率之间的相关性进行了进一步研究，其结果有利于反应器及运行参数的优化设计。

Abstract: A Bio-SR process， which is composed by iron salt absorption and Thiobacillus ferrooxidans， was used to remove H2S. The precipitation can be decreased by 83.9% by improving the culture conditions of the bacteria， which is propitious to solve the blockage of the biological packed tower in a certain extent and keeps the packed tower running continuously. The removal rate of H2S is above 98.4% under the selected conditions. The desulfurization reactor can run effectively and stably under the optimal conditions: Fe3+ concentration of 5.5～6 g/L， H2S concentration of 1 g/m3 and gas volume of 0.08～0.12 m3/h. In addition， the correlations among H2S concentration， gas volume and H2S removal rate were further studied， whose results are benefit to optimize the reactor and the operating parameters.
