生物吸附法处理水体中的重金属的现状与展望

对生物吸附法处理水体中的重金属进行了综述，得出微生物对重金属表现出良好的吸附性能，吸附机理比较复杂，与离子交换有密切关系，常用吸附等温线评价微生物对重金属的吸附能力。由于该研究历史比较短，生物吸附的工艺应用、机理分析、生物固定化等研究还不够深入，有待进一步的研究探索，使其应用于工业生产。

Heavy Metai Treatnent in Water by Biosorption

In this paper,heavy metal treatment in water by biosorption is summarized,which show that biosorption of heavy metal is fine.Mechanism of biosorption is complex,and it has intimate relation to ion-change.Biosorption capacity of heavy metal was evaluated by isotherm.As the history of investigation is short,the study of application,mechanism and granulation on biosorption is inadequate,and farther investigation is necessary,which will make biosorption industry application.
