摘　　要：近年来水体富营养化问题越来越严重,富营养化水体中某些藻类产生的微囊藻毒素对人类健康产生了极大威胁,而常用的水处理工艺难以将其彻底去除,开发用于处理微囊藻毒素的新技术越来越迫切。文章综述了各种高级氧化技术,包括化学氧化法、光催化氧化法、Fenton试剂及类Fenton试剂氧化法,降解微囊藻毒素的机理和效果,介绍了这些方法在微囊藻毒素处理方面的研究现状,并提出了今后在微囊藻毒素处理方面应该进一步研究的问题。In recent years, the problem of lake nourishment has become more and more serious and the microcystins produced by some algae has brought great menace to people＇s health. It is hard to degrade all the microcystins by using ordinary wastewater treatment process, so it is increasingly urgent to develop a new technology to deal with them. The mechanisms and effect of advanced oxidation processes for the degradation of microcystins are summarized, including chemical oxidation, photocatalytic and Fenton＇s reagent. It also introduces the current study of advanced oxidation processes in this field,as well as the issues of the degradation of microcystins in the future study.
