Experimental Study on Biological Treatment of Organic Waste Gas from Laboratory

The removal effect of simulation waste gas from laboratory, and the removal ability of benzene, toluene, xylene, ethanol, acetone, ethyl acetate and methane were studied in a biofilter tower. During the stable running period, the results showed that the removal efficiency of total volatile organic compounds (TVOCs) remained above 85%, when the inlet concentrations were 124~380 mg۰m-3. The removal efficiency of hydrophilic pollutants were higher than that of hydrophobic pollutants. The results proved that the biofilter tower was feasible to remove the organic waste gas from laboratory.
