摘要
生物吸附作为一种有效的去除水中重金属的方法引起人们的极大关注。近几年虽然提出了许多吸附模型,但生物体的吸附机理尚不完全清楚。生物吸附过程受生物体本身的性质、处理水的种类、离子强度、pH、反应动力学、反应设备等因素的影响。由于生物体在吸附和脱吸过程中具有非常好的可逆性,并且这种生物体大量存在,因此在水处理领域具有非常好的应用前景。作者主要介绍了近几年国外生物吸附法在水处理方面的研究成果。
Biosorption has attracted people′s attention as an effective method for the treatment of metal-bearing wastewater. In recent years, many models of the biosorption performance have been presented, but the mechanism of biosorption is not clearly understood. The process is affected by the properties of organism, the types of water bodies, ionic strength, pH, reaction kinetics and equipment of reaction. Due to good reversibility in the process of biosorption and desorption and the abundant amount of the biomass, the application of this process to water treatment is promising. The author mainly introduces the recent research achievement of biosorption.
