在饮用水源中，蓝藻（包括鱼腥藻属）和微囊藻（具有肝毒性）的毒性水华正变得越来越常见。正常的絮凝和氯化过程不能去除毒性。本文所述的实验室和中试工厂实验表明，粉末活性炭和颗粒活性炭均可去除毒性，无论是否添加氯化、明矾絮凝和聚电解质。包括13个参考文献、表格、图表。

Toxic blooms of cyanobacteria, including Anabaena species, which are neurotoxic, and Microcystis, which is hepatotoxic, are becoming increasingly common in potable water sources. Normal flocculation and chlorination processes do not remove the toxicity. The laboratory and pilot-plant experiments described in this article showed that the toxicity can be removed by both powdered and granular activated carbon, with and without chlorination, alum flocculation, and polyelectrolyte addition.
