Abstract
To remove hydrogen sulfide biologically, a three phase fluidized bed bioreactor was used in which Thiobacillus sp.IW was immobilized on biosands. The optimum operating condition of the bioreactor was found to be 30℃, pH 7, bed height of 0.85-1.0 m and aspect ratio of 1.0. At these conditions, the bioreactor removed more than 88 % of the hydrogen sulfide for an inlet concentration of 30-160 ppm and a gas flow rate of 2-5 l/m. The maximum removal rate obtained was about 1,000 mg H2S/min. In continuous operation of the bioreactor, the removal efficiency remained 99 % for up to 16 hours and decreased to 91 % at 52 hours.
