利用农业废弃物处理重金属离子废水的研究进展

Advances in Research on Treatment of Heavy Metal Ions Wastewater by Agricultural Waste

利用农业废弃物处理重金属离子废水是一种新型有效的方法,它具有低成本、高效率、可再生等优势,具有广阔的发展空间。近年来,各种农业废弃物对废水中重金属离子的去除效果得到了广泛的研究,但始终未对其进行系统的总结。为此,结合当前国内外研究进展,概述了农业废弃物处理重金属离子废水的吸附机理和吸附模型,并且详细总结了各种农业废弃物对铅、镉、镍、铜、锌、锰、汞等重金属离子的吸附处理效果,以期为进一步提升农业废弃物处理重金属离子废水的性能提供一定的理论指导。

Agricultural waste was used for heavy metal ions removal from wastewater. It was considered as a new method for treatment of heavy metal ions in wastewater. Its major advantages over conventional treatment methods included： low cost, high efficiency and regeneration of biosorption. This paper summarized studies on heavy metal ions removal from wastewater using various agricultural waste in recent years, especially underscored the mechanism and models, and sever- al heavy metals removal, like Pb, Cd, Ni, Cu, Zn, Mn and Hg, in order to provide theoretical guidance of using agri- cultural waste for removal heavy metal ions from wastewater.
