Abstract

PURPOSE: To deodorize a waste gas, by removing biologically hydrogen sulfide contained in it.
CONSTITUTION: In a housing of hermetic structure, the fixed filtering bed 2, wherein a sulfur bacterium (belonging to the genus Beggiatoa, Thiothrix, etc.) is attached to a proper substrate such as a honeycomb material, is put. A gas to be treated, containing hydrogen sulfide, is fed through the gas scattering pipe 4 to the chamber 3 for retaining a circulating liquid set at the bottom of the fixed filtering bed 2, and hydrogen sulfide is temporarily collected by the circulating liquid. Hydrogen sulfide is removed from the gas, while being transferred through the fixed filtering bed 2 to the chamber 5. The treated and deodorized gas is exhausted from the chamber 5 through the pipe 6. The fixed filtering bed 2 is made wet by the circulating liquid sprayed from the water scattering pipe 7, the liquid dropped to the chamber 3 for retaining it is returned from the pipe 8 to the water scattering pipe 7 by the action of the pump 9.
