【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。更多还原

【Abstract】 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/m3.Metabolism product of H2S is mainly composed of SO42-.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.更多还原
