絮凝剂在富营养化水体除藻应用中的研究进展

Research Progress of the Application of Flocculants in Removing Algae in the Eutrophic Waters

水生态系统的质量会直接影响社会经济的可持续发展,学者们广泛开展水体富营养化和有害水华的管控措施,絮凝法被大量用于大面积除藻,它能够快速且有效地处理水华暴发严重的水域。系统分析了国内外不同类型絮凝剂除藻性能的相关研究,尤其总结了新型无机-有机复合絮凝剂的发展与应用,并分析了絮凝剂在自然水体实际应用的案例,研究成果表明复合絮凝剂的科学使用能够结合有效提高絮凝效率、节约水处理成本,同时本文对今后的研究进行了展望。

The quality of aquatic ecosystems could directly affect the sustainable development of social economy and scholars have carried out extensive measures to control eutrophication and harmful algal blooms.Flocculation method has been widely used to remove algae in a large area,which could quickly and effectively treat waters with severe algal bloom outbreaks.In this paper,relevant domestic and foreign studies on the algae removal performance of different types of flocculants were systematically analyzed,especially on the development and application of new inorganic-organic composite flocculants are summarized.The practical application cases of flocculants in the natural water bodies were also analyzed.The results showed that the scientific use of composite flocculants could effectively improve flocculation efficiency and save water treatment costs.At the same time,the future research is prospected.
