摘要
水厂净水副产物铝污泥含有不定形铝的化合物并具有较为发达的微孔结构和较大的比表面积,对水中的阴离子有很强的亲和吸附能力。为资源化开发利用水厂污泥,国内外对铝污泥去除水体中污染物开展了大量研究。总结了铝污泥去除水中各种污染物的最新研究进展,特别是其在吸附固定环境中磷的特性方面的成果,对铝污泥在水环境领域的各种应用进行了论述,提出了未来铝污泥资源化利用的研究方向和发展趋势。
The aluminum-based water treatment residuals （AI-WTR）, a byproduct in water works, have a strong affinity for ionic species due to its microscopic pore structure and larger specific surface area. Currently, aiming to reclaim the A1-WTR, extensive researches have been carried out on the removal of a variety of contaminants from water by A1-WTR. The recent research progress on the pollutants removal performances in water by Al-WTR is reviewed in this paper, with a special focus on the adsorption characteristics of phosphorus by Al-WTR. The feasible applications of Al-WTR in water environment are also summarized and discussed; future study trends and needs are proposed and pointed out.
