| 摘 要： | 通过对比不同浓度铅离子存在条件下生物膜菌群的生长量,判断其对铅离子的耐受性;挑选吸附性强的菌群扩大培养,进一步作菌群驯化和铅的吸附试验;通过驯化前后吸附曲线和膜菌群的镜检观察对比,了解生物膜菌群在铅污染过程中的自净机制,为驯化生物膜处理含铅污染水体作了基础研究.

| Abstract: | The resistance-lead bacterium are identified in biofilms by determinating the amount of the bacterium in different concentrations of Pb2 .The highest resistance-lead bacterium are domesticated and the adsorption test to lead ions are carried out.The self-purification mechanism of bacterium are known in the process of polluted-lead based on the adsorption curve and the microscopical observation of bacterium before and after biosorption.This is the basic research on the biosorption of the polluted water containing lead ions with domesticated biofilms. |
