藻类对重金属废水的处理进展

Progress in Treatment of Heavy Metal Wastewater by Algae

重金属废水污染已经成为全球性的生态环境问题,利用自然水体中广泛存在的藻类处理重金属废水,因其有效、低廉和环保,以及较大的对重金属的吸附容量正成为国内外研究的热点,并且取得了一定的成效。本文将介绍在藻类的吸附容量、吸附机理和影响因素等方面取得的研究成果,同时指出当前的研究不足,并对今后的研究内容进行展望,以期促进该领域的发展。

Heavy metal wastewater pollution has become a global environmental problem. The alage has the advantages of high efficiency, inexpensive and environmental friendly as an adsorbent, which makes heavy metal wastewater treating by alage becomes a hot research at home and abroad. And this new method has already obtained certain result. In this article, we describe the research results of algae adsorption capacity, adsorption mechanism and the algae adsorption influence factors. In order to protnote the development of heavy metal wastewater treatment by alage, we also point out the lack of current research, and discussed the future of using heavy metal wastewater treatment by alage.
