活性污泥系统中 Cu2＋、Zn2＋竞争吸附规律研究进展

摘要

Based on the treatment status of municipal wastewater containing heavy metals , the adsorption law of heavy metals under differ-ent circumstances such as pH , temperature, adsorption time and activated sludge was simply described.The latest research results of com-petitive adsorption law of heavy metal at home and abroad were summarized.Finally, a brief analysis of the adsorption mechanism was giv-en.%从处理含重金属离子的城市污水的现状出发，简述了在不同pH值、温度、时间、活性污泥等条件下重金属离子的吸附规律，综述了目前国内外有关活性污泥系统中，重金属离子竞争吸附规律的最新研究成果，并对其吸附原理进行了解析。
