摘要(Abstract)：

针对石油化工行业排放的恶臭硫醇和苯、甲苯、乙苯及二甲苯（benzene，toluene，ethyl benzene and xylenen，BTEX）污染物，采用生物法对其进行去除。在生物滴滤塔（biotrickling filter，BTF）中接种二甲苯降解菌Pandoraea sp. WL1和硫醇降解菌Pseudomonas sp. WL2，对硫醇和BTEX的去除性能、动力学特性及微生物群落特性进行详细研究。运行结果表明，优选菌的接种能大大缩短BTF的启动时间。宏观动力学分析表明，该体系混合VOCs的最大去除能力为210.7 g·m^-3·h^-1。16S rRNA测序表明，在经过长时间混合底物的通入后，Hydrogenophaga（17.2%）和Pseudomonas（8.1%）取代Pandoraea成为BTF内的主导菌属。Thiobacillus（4.5%）和Pseudomonas（8.1%）菌属在恶臭硫醇的生物降解中起关键作用。
