本实验以甲苯为目标污染物、陶粒为填料、实验室前期驯化筛选得到的优势甲苯组合菌为菌源进行实验，研究立式生物滴滤塔的挂膜启动情况及在稳定运行阶段甲苯进气浓度、短期停置对甲苯去除率的影响。>The　contained　gas　purification　by　vertical　bio-trickling　filter　was　performed　with　toluene　as　target　pollutant,　ceramists　as　packing　material　and　the　efficient　composite　bacteria　as　degrading　bacteria,　the　efficient　assorted　bacteria　are　obtained　from　earlier　experiments.　The　start-up　process　of　the　bio-trickling　filter　was　studied;　the　effects　of　inlet　toluene　concentration　and　short-term　stop　on　removal　capacity　under　stable　operation　stage　were　also　investigated.
