Abstract
The fixed-film bioscrubber was developed for hydrogen sulfide removal.
Acinetobacter sp. MU1_03 and Alcaligenes faecalis MU2_03 are two
new strains of microorganisms from the fixed-film bioscrubber systems
found. Under certain conditions, they exhibited more than 91% of
hydrogen sulfide removal efficiency while a mixture of the two strains
was capable of 98% hydrogen sulfide removal. Removal efficiency
increased with decreasing inlet gas flow rates, increasing the height of
packing and empty bed retention time. During the operation, the pH
decreased but did not fall below 6.4. Sulfate production increased when
the removal efficiency increased due to the oxidation of hydrogen sulfide
to sulfate. In addition, dissolved oxygen decreased during the same
reaction.
