摘　　要：以纳米活性陶瓷球为生物滴滤塔填料,利用基因工程改造大肠杆菌和铜绿假单胞菌为底盘菌进行挂膜,结合物理吸附开展生物滴滤系统净化甲苯废气的研究。结果表明,混菌体系在含甲苯培养基中生长良好,且大肠杆菌与铜绿假单胞菌不形成竞争,二者相互利用、相互促进;当生物滴滤系统运行96 h时,生物滴滤塔去除率可达96.7%,总去除率可达97.2%。Nano active ceramic ball is used as the filler of trickling tower,the genetically engineered E.coli and Pseudomonas aeruginosa are used as the baseplate bacteria to hang the membrane,and the biological trickling filter system combined with activated carbon physical adsorption is employed to purify toluene-containing waste gas.Research results show that the mixed bacteria system grows well in the toluene-containing culture medium and can effectively achieve the degradation of toluene.There is no competition between E.coli and Pseudomonas aeruginosa,they utilize and promote each other.The removal rate of toluene by the biological trickling filter tower can reach 96.78%and total removal rate of toluene can reach 97.19%after the biological trickling filter system has run for 96 hours.
