【摘要】 选取塑料鲍尔环和圆柱状活性炭作为填料,采用生物滴滤塔对于船舶舱室低浓度苯的生物净化效率和去除负荷进行了研究。实验测定了填料种类、填料高度、进气浓度、停留时间等操作因素对净化效率的影响。结果表明,在实验操作范围内,生物滴滤塔Ⅰ、Ⅱ、Ⅲ对于苯的最大去除负荷分别达到36.97,79.14和185.42 mg/(L.h),组合填料的净化效率和去除负荷都优于单一填料。更多还原

【Abstract】 A biotrickling filter packed with plastic Pall ring and columned activated carbon has been developed,and the removal efficiency(RE)and elimination capacity(EC)of low concentrated benzene in marine cabins were investigated.Several operational parameters including performance and height of packing materials,benzene inlet concentration,gas residence time,which influence the removal efficiency,are tested experimentally.In the operated BTF Ⅰ,Ⅱ,Ⅲ,the maximum elimination capacities for benzene reached 36.97,79.41,185.42 mg/(L·h) respectively.The results showed that compound packing materials has higher biodegradation efficiency than that of above two single packing materials.更多还原
