Description
Summary:X512; A bench-scale experiment for control of hydrogen sulfide (H2S) emissions was carried out continuously for nearly four months by using bio-trickling filter packed with ZX01 stuffing. The results suggested that the bio-trickling filter had proven excellent performance over substantial operational periods. Removal efficiency of H2S was nearly 100% when volumetric loading of the bio-trickling filter varied from 0.64 g/(m3·h)to 38.20 g/(m3·h) and metabolism products of H2S were mainly composed of SO42-. When inlet concentration of H2S was 250 mg/m3, the optimum gas retention time was 30 s and the optimum spray water not blocked during experiments for nearly four months during which resistance was maintained at relatively lower value, so that the bio-trickling filter need not carry out back washing frequently and can be operated steadily for long-term.
