摘要
根据趋磁性细菌的特性,对活性污泥进行了微好氧条件下的富集,培养一个月后,对趋磁性细菌进行电镜观察,测定了混合菌的生长曲线。在一定条件下进行的趋磁性细菌吸附Pb2+的试验表明,趋磁性细菌对Pb2+的吸附效果很好,去除率几乎达到100%,其吸附过程能很好地符合Langmiur吸附模型。
The magnetic characteristics of magnetotactic bacteria （MTB） were introduced. Biosorption of plumbum （ Ⅱ ） was carried out with the activated sludge cultivated by the micro aerobe culture conditions for 1 month. At the same time, MTB was observed by Scanning Electron Microscope （SEM） and Transmission Electron Microscope（TEM）. The growing curve of MTB was measured also, The result indicated that MTB would be effective to adsorb Pb^2＋ when the activated sludge was cultivated on the micro aerobe condition, The total removal of Pb^2＋ was nearly 100% . The adsorption data were followed by Langmuir model.
