摘　　要：针对蓝藻水华出现的频率与分布因水体富营养化加剧而不断激增,引发的藻毒素污染问题已严重威胁生态环境与人类健康这一情况,基于微囊藻毒素的分子结构与理化性质出发,以活性炭的高孔隙率与多吸附位点等特性为基础,阐明了活性炭对微囊藻毒素的吸附机理,叙述了吸附过程中活性炭与微囊藻毒素的性质和水环境的天然有机物、p H及离子强度对吸附性能的影响,总结了目前改性活性炭、生物活性炭与生物质基活性炭的应用发展。并结合活性炭吸附技术存在的问题对未来研究工作进行分析,认为需要确定各类生物活性炭性质的影响机制,深入研究MCs高效降解菌的发酵培养与优势菌固定化技术,开发高效稳定的组合工艺,以实现MCs的彻底去除。The frequency and distribution of cyanobacterial blooms are continuously increasing due to the eutrophication of water bodies. The pollution of algae toxin caused by cyanobacteria has already seriously threatened the ecological environment and human health. Based on the molecular structure and physicochemical properties of microcystins, the activated carbon adsorption mechanism for microcystins was elucidated in view of the high porosity and many adsorption sites. The characteristics of activated carbon and microcystins, and the effect of natural organic matter, p H and ionic strength of water environment on the adsorption performance were described. The application of modified activated carbon, biological activated carbon and biochar were summarized. In addition, combined with the existing problems of activated carbon adsorption technology, the future research work was analyzed,the influencing mechanism of all kinds of biological activated carbon should be determined, the fermentation cultivation of efficient degrading bacteria for MCs and immobilization technology of dominant bacteria should be researched in depth, efficient and stable combined process should be developed to realize removal complete of MCs.
