摘　　要：近年来,随着水体富营养化程度加剧,蓝藻水华现象时有发生,蓝藻及其释放的藻毒素对生态环境和人类健康构成严重威胁.本文概述了常见藻毒素的分类及其主要理化性质,总结了生物接触氧化、生物滤池和生物-生态耦合等工艺对藻毒素的去除性能与机制,分析了生物处理工艺的反应条件(温度、pH和水力停留时间)、原水性质及营养限制等影响因素,并对藻毒素去除机理、新工艺研发等方面进行了展望.In recent years, eutrophication has not been effectively controlled and algal pollution still breaks out frequently. At the same time, the cyanobacteria and release of algal toxins have posed a serious threat to the environment and human health. In this review, the classification and main physicochemical properties of algal toxins were summarized, and the biological removal strategies of algal toxins including biological contact oxidation process, biological filter process and biological ecological coupling process and their biodegradation mechanisms were reviewed. The influence factors on biological treatment process, including operation conditions （temperature, pH and hydraulic retention time）, water property and nutrient limitation factors, were analyzed. The research on the removal mechanisms of other algae toxins and the development and optimization of new biological technology were prospected to develop and improve algal toxin removal technology and ensure drinking water safety.
