The structures,characteristics and microbial diversities of biofilm in biotrickling filter( BTF) for the degradation of ethylbenzene were studied during the long-term stable operation periods. The results show that the degradation performance of ethylbenzene kept stable in BTF during 95 d. The degradation efficiencies were more than 90% while the maximum removal rate was 62.4 g·m~(-3)·h~(-1). along the gas flow direction,The biofilm pattern,color and thickness gradual change and the biomass and biofilm dens...
1引言(Introduction)近年来,挥发性有机物(VOCs)的大量排放与累积引发一系列大气环境问题,严重影响了人类生存环境、制约了经济发展(Wang et al.,2007).生物过滤技术与传统大气污染技术相比,具有经济、高效、无二次污染等特点,是近年VOCs治理主流技术之一,在实际处理低浓度大流
