title: [Removal of Waste Gas Containing Mixed Chlorinated Hydrocarbons by the Biotrickling Filter].
abstract: An experimental investigation on purification of waste gas contaminated with a mixture of dichloromethane (DCM) and dichloroethane(1,2-DCA) was conducted in a biotrickling filter (BTF) inoculated with activated sludge of pharmaceuticals industry. Stable removal efficiency(RE) above 80% for DCM and above 75% for 1,2-DCA were achieved after 35 days, indicating that biofilm was developed. The best elimination capacity (EC) of DCM and 1,2-DCA were 13 g.(m3.h)-1 and 10 g.(m3.h)-1 respectively. And there was a linear relationship between the production of CO2 and mixed gas EC, the maximum mineralization rate of mixed gas stabled at 61. 2%. The interaction test indicated that DCM and 1,2-DCA would inhibit with each other. The changing of biomass of BTF during the operation process was also been studied.
