摘要

对生物法净化低浓度甲苯废气的适宜装置及其操作特性的研究表明，生物膜填料塔对低浓度甲苯废气的净化性能优于筛板塔及鼓泡塔；生物膜填料塔采用逆流并在液气比0.03～0.1、气速（30～60）m·h~(-1)的条件下操作时，低浓度甲苯废气净化效率可保持在90％以上．经实验验证，本生物膜填料塔对废气中甲苯的同系物同样具有净化作用．并且对再生胶厂、印刷厂、铸造厂、油漆厂等企业的实际生产废气也有良好的净化效果．

Abstract

The equipment and its operating characteristics of purifying waste gas containing low concentration toluene by using biological method were investigated.The results showed that the purification performance of a packing column with biofilm-material packing was better than that with sieve-plate column and bubble column.When the biofilm-packing column was operated countercurrently under the conditions of liquid/gas ratio of 0.03～0.1 and gas velocity（30～60）m·h~-1，more than 90％ of toluene in the waste gas could be removed.It was confirmed in the experiments that the biofilm-packing column also could remove toluenes homologues from the waste gas.It was found that the biofilm-packing column showed good capability for removing toluene and other organic compounds from waste gases
