ABSTRACT

o

-Dichlorobenzene could be mineralized as the sole carbon and energy source by Bacillus cereus DL-1. In this work, Haldane–Andrews and pseudo-first-order models were used to simulate the growth and degradation abilities of the strain. Two possible degradation pathways were identified by GC/MS intermediate and open-loop analysis. The removal efficiency (RE) of biotrickling filter (BTF) could reach 57.86% at the start phase. At the steady phase, the effects of empty bed residence time (EBRT), inlet gas concentration and intake load rate (ILR) on the performance of BTF have highlighted the potential of strain DL-1 for the treatment of o-dichlorobenzene.

蜡状芽孢杆菌DL-1对邻二氯苯的生物降解：动力学，降解途径，生物降解性及生物滴滤性能

摘要

Ø

-蜡状芽孢杆菌DL-1可将二氯苯矿化为唯一的碳和能源。在这项工作中，Haldane-Andrews和伪一阶模型用于模拟菌株的生长和降解能力。通过GC / MS中间体和开环分析确定了两种可能的降解途径。在开始阶段，生物滴滤池（BTF）的去除效率（RE）可以达到57.86％。在稳定阶段，空床停留时间（EBRT），进气浓度和进气负荷率（ILR）对BTF性能的影响突显了菌株DL-1在邻二氯苯处理中的潜力。
