Abstract
Bio-purification test of the seven kinds of gaseous pollutants, toluene, styrene, formaldehyde, CS2, SO2, H2S and NOx, which are commonly contained in industrial waste gases, by using the biofilm-packing tower system was performed. The test results showed that the biofilm-separately. And the purifying effects of biofilm-packing towers for three kinds of inorganic pollutants, SO2, H2S and NOx (bio-elimination capacity B = 90 — 150 mg/L·h) , were better obviously than that for three kinds of organic pollutants, styrene, formaldehyde and CS2, (bio-elimination capacity B < 30 mg/L·h) . The suitable operation conditions of the biofilm-packing tower system for purifying the 7 kinds of gaseous pollutants were confirmed and the seven kinds of special bacteria strains were identified in this study.
