Experimental Study on Biological Treatment of Organic Waste Gas from Laboratory

Abstract:

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.
