中文摘要：
用使不能调动的微生物引起的房间的 di-n-butyl phthalate (DBP ) 的简历降级与陶器的蜂房支持在一个内部空运环反应堆被执行。能够降级的紧张 DBP 从活性污泥被孤立并且作为杆菌 sp 识别了。用 16S rDNA 顺序的分析。杆菌 sp。能很快被依附到陶器的蜂房支持上。使不能调动的房间能有效地降级在批和连续实验的 DBP。当 DBP 的流入的集中是 50mg .L 时(-1), 自河 DBP 到达了不到 1mg .L (有 6h 的 -1) 在连续实验的水力的保留时间(HRT ) 。使不能调动的微生物引起的房间能通过降级的 DBP，和率的简历降级成长并且积累因此被增加。用使不能调动的房间的 DBP 简历降级的可能的小径尝试性地被建议。给词调音：简历降级；苯二甲酸酉旨；优先级污染物质；生物反应器；使不能调动的房间
英文摘要：
The biodegradation of di-n-butyl phthalate （DBP） using immobilized microbial cells was carded out in an internal airlift loop reactor with ceramic honeycomb supports. A strain that is capable of degrading DBP was isolated from the activated sludge and identified as Bacillus sp. using 16S rDNA sequential analysis. Bacillus sp. could be rapidly attached onto the ceramic honeycomb supports. The immobilized cells could effectively degrade DBP in batch and continuous experiments. When the influent concentration of DBP was 50mg·L^-1, the effluent DBP reached less than lmg.L i with 6h hydraulic retention time （HRT） in continuous experiment. The immobilized microbial cells could grow and accumulate through the biodegradation of DBP, and the rate of degradation is accordingly increased. The possible pathway of DBP biodegradation using immobilized cells was tentatively proposed.
