In recent years, the proliferation of Harmful Cyanobacterial Blooms (CyanoHABs) has increased with water eutrophication and climate change, impairing human health and the environment in relation to water supply. In drinking water treatment plants (DWTPs), the bio-coagulation based on natural coagulants has been studied as an eco-friendly alternative technology to conventional coagulants for both turbidity and CyanoHABs removal. Plant-based coagulants have demonstrated their coagulation efficiency in turbidity removal, as reported in several papers but its ability in cyanobacterial removal is still limited. This paper mainly reviewed the application of plant-based coagulants in DWTPs, with focus on turbidity removal, including cyanobacterial cells. The future potential uses of these green coagulants to reduce noxious effects of cyanobacterial proliferation are presented. Green coagulants advantages and limitations in DWTPs are reviewed and discussed summarizing more than 10 years of knowledge.
近年来，随着水体富营养化和气候变化，有害蓝藻水华（CyanoHABs）的爆发有所增加，这对供水相关的人类健康和环境造成了损害。在饮用水处理厂（DWTP）中，基于天然混凝剂的生物混凝已被研究为替代传统混凝剂的环保技术，用于去除浊度和 CyanoHABs。已有多篇论文报道了植物源混凝剂在去除浊度方面的混凝效果，但在去除蓝藻方面的能力仍然有限。本文主要综述了植物源混凝剂在 DWTP 中的应用，重点介绍了其去除浊度，包括蓝藻细胞的能力。本文还提出了这些绿色混凝剂在减少蓝藻增殖的有害影响方面的未来潜在用途。本文综述和讨论了 DWTP 中绿色混凝剂的优缺点，总结了 10 多年的相关知识。
