纳米级水处理絮凝剂的研究进展

Research progress of nano materials as flocculants in water treatment

近年来,纳米水处理材料的发展受到了极大的关注。从工业技术角度看,纳米材料在21世纪水处理中的应用将是先进材料设计、加工和进步的重点。在这种情况下,利用不同类型的絮凝剂来净化受污染的水,对于解决全球高水平工业化持续带来的水污染至关重要。许多研究人员为此目的研究了各种纳米絮凝剂的效果。尽管这些纳米絮凝剂已被报道成功地处理了受污染的水,但它们的絮凝性能不同。综述了近年来各种纳米絮凝剂在处理重金属、染料和微污染水体方面的研究进展。

In recent years,the development of nano water treatment materials has attracted great attention.From the perspective of industrial technology,the application of nano materials in water treatment in the 21st century will be the focus of advanced material design,processing and progress.In this case,the use of different types of flocculants to purify the polluted water is very important to solve the water pollution caused by high-level industrialization in the world.Many researchers have studied the effect of various nano flocculants for this purpose.Although these nano flocculants have been reported to have successfully treated polluted water,their flocculation performance is different.In this paper,the research progress of various nano flocculants in the treatment of heavy metals,dyes and micro polluted water in recent years is reviewed.
