Abstract:
The research on bio-based flocculants for waste resource utilization and environmental protection has garnered significant attention. Bio-based flocculants encompass plant-based, animal-based, and microbial variants that are prepared and modified through biological, chemical, and physical methods. These flocculants possess abundant functional groups, unique structures, and distinctive characteristics. This review comprehensively discussed the removal rates of conventional pollutants and emerging pollutants by bio-based flocculants, the interaction between these flocculants and pollutants, their impact on flocculation performance in wastewater treatment, as well as their application cost. Furthermore, it described the common challenges faced by bio-based flocculants in practical applications along with various improvement strategies to address them. With their safety profile, environmental friendliness, efficiency, renewability, and wide availability from diverse sources, bio-based flocculants hold great potential for widespread use in wastewater treatment.
摘要:
生物基絮凝剂在废物资源化利用和环境保护方面的研究已引起广泛关注。生物基絮凝剂包括植物基絮凝剂,以动物为基础,以及通过生物方法制备和修饰的微生物变体,化学,物理方法。这些絮凝剂具有丰富的官能团,独特的结构,和鲜明的特点。本文综合论述了生物基絮凝剂对常规污染物和新兴污染物的去除率,这些絮凝剂和污染物之间的相互作用,它们对废水处理中絮凝性能的影响,以及他们的应用成本。此外,它描述了生物基絮凝剂在实际应用中面临的共同挑战,以及解决这些挑战的各种改进策略。有了他们的安全档案,环境友好,效率,可再生性,以及来自不同来源的广泛可用性,生物基絮凝剂在废水处理中具有广泛使用的巨大潜力。
