摘　　要：在(50(750mm装有聚丙烯散堆填料的生物滴滤池内进行二氯甲烷废气处理可行性研究.由工厂活性污泥经驯化培养得到的菌种在此填料上挂膜约需30d.空塔气速、进口浓度对二氯甲烷的去除率有较大影响.当二氯甲烷进口浓度为0.70~3.12g/m3、空塔气速为30.6~ 122.4m/h时,二氯甲烷的去除率为45.1%~99.1%.滴滤池中的酸性环境对二氯甲烷的降解有影响.In a f50750mm biotrickling filter packed with randomly-stacked polypropylene, the possibilities of treating waste gas containing dichloromethane was studied. A bacterium strains obtained from facility抯 activated sludge through domestication and culture was inoculated over the surface of the packing to form a biofilm after 30 days. The empty-bed gas velocity and the inlet concentration had great effect on the removal rate of dichloromethane. When the inlet concentration of dichloromethane was 0.70~3.12g/m3 and the empty-bed gas velocity was 30.6~122.4m/h, the removal rate was 45.1%~99.1%. The acid environment in the filter could influence the degradation of dichloromethane.
