Comparison of Three Types of Fillers in Bio-treatment for Removal of H2S from Biogas
A bio-trickling filter was self-designed and installed for desulfurization in this study. Three types of fillers, PVC material, activated carbon, activated carbon fiber were chosen for comparing the eliminated efficiency of hydrogen sulfide in biogas. The results showed that Supernatant of activated sludge was more effective in removing H2S than pure water. The order of domestication and bio-film holding ability was activated carbon fiber>activated carbon>PVC material. Therefore, activated carbon fiber was chosen as the carrier of the desulfurization microbe. The removal rate of H2S up to 98.0％ or more can be obtained under the following experimental conditions: a maximum H2S load of 60L/h, pH of 2-5 and a spray flow rate of 120 L/m3.d.
