摘　　要：A bench-scale experiment for control of hydrogen sulfide （H2S） emissions was carried out continuously for nearly four months by using bio-trickling filter packed with ZX01 stuffing. The results suggested that the bio-trickling filter had proven excellent performance over substantial operational periods. Removal efficiency of H2S was nearly 100% when volumetric loading of the bio-trickling filter varied from 0.64 g/（m^3·h） to 38.20 g/（m^3·h） and metabolism products of H2S were mainly composed of SO4^2-. When inlet concentration of H2S was 250 mg/m^3, the optimum gas retention time was 30 s and the optimum spray water flow rate was 0.005 9-0.012 L/（cm^2·h）. The bio-trickling filter had good ability to resist shock of high volumetric loading, and was not blocked during experiments for nearly four months during which resistance was maintained at relatively lower value, so that the bio-trickling filter need not carry out back washing frequently and can be operated steadily for long-term.为氢硫化物(H2S ) 的控制的一个凳子规模实验排出物被使用与 ZX01 填满包装的流简历的过滤器连续地执行将近四个月。结果建议流简历的过滤器在实质的运作的时期上证明性能优秀。H2S 的移动效率是将近百分之百当从 0.64 g/ 改变的流简历的过滤器的容量的装载时(m [3 ]· h ) 到 38.20 g/(m [3 ]· h ) ；H2S 的新陈代谢产品主要由 SO4 组成[2 ] 。当 H2S 的入口集中是 250 mg/m 时[3 ] ，最佳气体保留时间是 30 s；最佳水花水流动率是 0.0059 ～ 0 .012 L/( 厘米[2 ]· h ) 。流简历的过滤器有好能力抵抗高容量的装载的吃惊，；没在哪个电阻在相对更低的价值被维持期间在实验期间被堵住将近四个月，以便流简历的过滤器不必执行回来经常洗；能稳定地被操作为长期。
