摘　　要：生物吸附是微生物细胞和其它物质发生的一系列非发酵关联的吸附过程,其主要作用包括物理和化学吸附、静电作用、离子交换、络合、螯合、微量沉淀等。与生物降解相比,生物吸附不会产生有毒的代谢产物,为染料废水的处理和回收提供了一条经济可行的途径。综述了微生物对染料吸附的作用机制及影响因素如pH、温度、染料初始浓度等,介绍了生物吸附的发展现状及前景。Biosorption is a series of adsorption processes between microbial cells and other substances without relationship to fermentation, including physical and chemical absorption, static electrification, ion exchange, complexation, chelation and micro - precipitation, and so on. Compared with biodegradation, no toxic metabolic product is produced in biosorption, and it provides an economical and feasible way for treatment and recovery of dyeing wastewater. Biosorption mechanism of dyes and affecting factors such as pH, temperature, initial concentration of dyes are summarized. The research progress and development prospect in biosorption are introduced.
