Removal of o-xylene from waste gases by biotrickling filter
摘要
Abstract
Emission of o-xylene has a great harm on the environment and human health,the research on the treatment of o-xylene from waste gases by biotrickling filter is rare at present.Use o-xylene as the sole carbon source to cultivate the activated sludge which getted from a coking plant,get o-xylene-degrading mixed cultures finally.And then add the domesticated mixed cultures to the biotrickling filter,which filled with polypropylene biological carrier.After biofilm that on the biological carrier is stable,we study on the removal efficiency changes of o-xylene from waste gases in the changing experimental condition,the room temperature:20～30 ℃C,pH:5 ～ 7,empty biofilter residence time:40,60,100 s.Result shows that it can deal with low concentration o-xylene from waste gases effectively with the biotrickling filter,which could be influenced by temperature,empty biofilter residence time,concentration of inlet and other condition.关键词
