Blooms of toxic cyanobacteria in water supply systems are a global issue affecting water supplies on every major continent except Antarctica. The occurrence of toxic cyanobacteria in freshwater is increasing in both frequency and distribution. The protection of water supplies has therefore become increasingly more challenging. To reduce the risk from toxic cyanobacterial blooms in drinking water, a multi-barrier approach is needed, consisting of prevention, source control, treatment optimization, and monitoring. In this paper, current research on some of the critical elements of this multi-barrier approach are reviewed and synthesized, with an emphasis on the effectiveness of water treatment technologies for removing cyanobacteria and related toxic compounds. This paper synthesizes and updates a number of previous review articles on various aspects of this multi-barrier approach in order to provide a holistic resource for researchers, water managers and engineers, as well as water treatment plant operators.
水供应系统中有毒蓝藻的大量繁殖是一个全球性问题，除南极洲外，各大洲的水供应都受到了影响。有毒蓝藻在淡水中的出现频率和分布范围都在增加。因此，保护水供应变得越来越具有挑战性。为了降低饮用水中有毒蓝藻大量繁殖的风险，需要采取多道防线的方法，包括预防、源头控制、处理优化和监测。本文综述和综合了多道防线方法中的一些关键要素的当前研究，重点是水处理技术去除蓝藻和相关有毒化合物的有效性。本文综合和更新了之前关于多道防线方法各个方面的多篇综述文章，为研究人员、水管理人员和工程师以及水处理厂操作人员提供了一个全面的资源。
