摘　　要：为了治理H2S恶臭污染,研究采用装有ZX01型填料的生物滴滤塔,进行了长期实验室H2S脱臭试验。结果表明:该生物滴滤塔H2S的进气浓度低于300 mg/m3时,气体最佳停留时间为30 s,去除率接近100%,H2S代谢产物以硫酸根离子为主。该滴滤塔阻抗较低,无需经常进行反冲洗,可长期稳定运行。In order to dispose of H2S odor pollution, a long-term lab-scale deodorization experiment is carried out continuously by bio-trickling filter packed with ZX01 stuffing. The results show that the removal efficiency of H2S is nearly 100% and the optimum gas retention time is 30 s when inlet concentration of H2S is 300 mg/m^3. Metabolism product of H2S is mainly composed of SO4^2-. The bio-reactor is not blocked in the experiment in which the resistance is maintained at lower value. The bio-trickling filter needs not carry out a back washing frequently, and it can be operated steadily for a long term.
