生物炭应用于湿地水生态修复的研究进展

Research Progress on the Application of Biochar in the Wetland Water Ecological Restoration

湿地构建中基质填料对其综合且持久发挥效能具有关键作用。生物炭可以通过吸附、分配等作用固定水中污染物,填充于湿地基质中能发挥其减污降碳协同增效的巨大潜力。该文开展了生物炭基湿地水质净化效能、污染物迁移转化过程与机制等研究,揭示了生物炭种类和物化特性对水生植物生长、微生物群落繁衍和固碳减排等方面的作用机理,为生物炭的施用和湿地建设提出新的研究方向,对提升水生态的可持续性具有重要意义。

In the construction of wetland water landscape,matrix filler plays a key role in its comprehensive and lasting performance.It can fix the pollutants in the water environment through adsorption and distribution,filling in the wetland matrix can give full play to its huge potential of pollution reduction,carbon reduction and synergistic efficiency.This paper carried out researches on water purification efficiency of biochar-based wetlands,the process and mechanism of pollutant migration and transformation.The effects of biochar species and physico-chemical characteristics on the growth of aquatic plants,the propagation of microbial communities,carbon sequestration and emission reduction were revealed.This study proposes a new research direction for biochar application and wetland construction,plays an important role in enhancing the sustainability of water ecology.
