| 摘 要： | 为研究多种氟喹诺酮对人工湿地净化能力和微生物群落的影响,在人工湿地进水中添加两个月氧氟沙星、诺氟沙星和环丙沙星,监测水质变化和微生物群落变化.结果表明,进水中添加抗生素后,COD去除率逐渐降低,最低达到70.94%,但其可随着时间的延长逐步恢复.TP去除率在添加抗生素后也出现下降并有较大波动.氨氮去除率维持稳定状态.可见,氟喹诺酮对人工湿地的COD和TP净化能力有较大影响,对氨氮去除无显著影响.微生物群落方面,抗生素添加前后的Shannon指数和Shannoneven指数无显著变化,但Chao1指数显著增加.对比前和后两组的群落构成发现,Proteobacteria的相对丰度明显减小(从44.90%降低至34.12%),但其仍是优势种群,Firmicutes的相对丰度明显增加(从2.55%增加至10.55%).纲水平上,β-Proteobacteria相对丰度从17.03%降低至8.36%,Clostridia、Bacilli、Bacteroidia相对丰度分别从0.50%、1.85%、0.10%增加至4.21%、4.64%、2.56%.在属的分类水平上,Dechloromonas和Pseudarthrobacter的相对丰度明显下降,分别从8.56%、5.10%下降至3.16%、1.53%,Trichococcus、Tessaracoccus和Desulfovibrio的相对丰度则分别从0.66%、0.03%、0.02%增加到了3.84%、3.83%、2.06%.因此,氟喹诺酮使人工湿地中的微生物群落发生了转变.
