摘　　要：采用焦炭为填料的生物滤床降解苯乙烯废气 ,试验过程中对焦炭进行循环挂膜 ,发现焦炭对苯乙烯这样的挥发性有机物 (VOC)初期以吸附作用为主 ,随着生物膜的长成生物降解作用逐渐占有优势 ,表现为对苯乙烯的去除效率稳定在 35 %～ 5 5 %左右。The Biofilter packed with coke was utilized to degrade styrene-containing wastegas. We also carryed out circulation aeratating study of biofilm growth on the coke. At first, the adsorption action of cokes was dominating. When cokes were all covered with biofilm , the biodegreding action of biofilm was principal.Then the removal effect of styrene in biofilter was about from 35 to 55 percent steadly.
