Abstract:

利用选择性培养基分离出铜抗性细菌BX,经鉴定该菌为产碱普罗威登斯菌(Providenciaalcalifaciens)。考察了细菌BX对环境的适应性,讨论了pH、初始Cu2+浓度等对其吸附铜离子的影响,分析了吸附过程的动力学及等温吸附特性,并以多孔陶瓷为载体对其进行固定化。结果表明,该菌对Cu2+和NaCl的抗性浓度分别为7mmol·L-1和7.5%,可生长于pH4.0~11.0、15~50℃的环境中;其最佳吸附条件为pH5.5、温度30℃、起始Cu2+浓度100mg·L-1,在该条件下,Cu2+吸附率达85.84%,吸附量为128.74mg·g-1;其对Cu2+的吸附符合准二级动力学方程和Freundlich等温吸附模型;采用曝气挂膜法将细菌固定于多孔陶瓷上,形成的菌膜对50mg·L-1铜离子的吸附率达92.53%。表明细菌BX对Cu2+有较强的吸附能力,对含Cu2+废水的处理具有良好的应用前景。
