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.
