摘　　要：好氧颗粒污泥因独特的表面多孔性而被用作重金属离子的生物吸附材料。简述了好氧颗粒污泥吸附重金属离子的机理,讨论了溶液pH值、吸附时间、重金属离子初始浓度、好氧颗粒污泥浓度、好氧颗粒污泥粒径、吸附温度、共存离子等因素对好氧颗粒污泥吸附重金属离子的影响,并对重金属离子的解吸方式进行了讨论;综述了好氧颗粒污泥吸附重金属离子的国内外最新研究进展,展望了以好氧颗粒污泥作为生物吸附材料处理重金属废水的应用前景。Aerobic granular sludge can be used as a biological adsorption material to adsorb heavy metal ions due to its unique porous surface. The adsorption mechanism by aerobic granular sludge is briefly described. The factors,such as pH value of solution,adsorption time,initial concentration of heavy metal ions,concentration of aerobic granular sludge,the diameter of aerobic granular sludge,adsorption temperature,coexistent ions and so on that affecting the adsorption of heavy metal ions by aerobic granular sludge are discussed. The desorption mode of heavy metal ions is also introduced. The latest research advances in adsorption of heavy metal ions by aerobic granular sludge are reviewed. The prospect of aerobic granular sludge applied to the treatment of wastewater containing heavy metals ions is looked forward.
