摘　　要：介绍了国内外对原水中藻类、藻毒素的去除方法,其中对藻类及其胞内藻毒素的去除主要有预过滤、强化混凝、气浮等技术,对细胞外溶解性藻毒素的去除主要有生物预处理、活性炭吸附、膜过滤、臭氧及紫外线等高级氧化工艺。通过分析这些工艺的优缺点及研究进展,提出了一些可行性优化组合方案并展望了可能的发展方向。The domestic and foreign methods for removal of algae and algal toxins from raw water were introduced. The drinking water treatment processes used for removal of algae and intracellular toxins are mainly prefiltration, enhanced coagulation, flotation and so on. The removal processes of extracellular dissolved toxins are biological pretreatment, activated carbon adsorption, membrane filtration, ozone oxidation, ultraviolet radiation and other advanced oxidations. By analyzing the merits and demerits of these processes and the research progress, some feasible combined processes were put forward, and the possible development directions were prospected.
