Preparation of biological activated bamboo charcoal and its use to remove quinoline from waste water

摘要: 以自制活性竹炭( Activated Bamboo Charcoal，简称ABC )为基体，负载喹啉降解菌BC027制备了生物活性竹炭( Biological Activated Bamboo Charcoal，简称BABC )，并研究了BABC去除目标污染物——喹啉的性能。结果表明：喹啉降解菌可以负载到ABC表面，且生长状态良好。与ABC相比，BABC去除喹啉的过程可分为三个阶段，其中降解期微生物作用明显；BABC去除喹啉的能力和溶液中OD值的大小相关，基体吸附性能仅在吸附期起作用。BABC的处理容量大于ABC，使用寿命长于ABC。Abstract: A strain of bacterium (BC027) for quinoline degradation was inoculated on an activated bamboo charcoal (ABC) substrate to obtain biological activated bamboo charcoal (BABC). SEM micrographs showed that microbe can grow well on ABC. The quinoline removal by the BABC was divided into 3 stages, adsorption, interim and degradation. The degradation played a key role in these stages, which was related to the optical density of bacteria in the solution. In contrast, the adsorption of quinoline on BABC only happened at the first stage. The BABC exhibited higher treatment capacity and longer use life than did ABC.
