摘　　要：水体污染越来越普遍,严重地威胁着人类的健康,特别是含油含重金属离子的废水,对这些废水的净化处理迫在眉睫。调查研究发现,改性后的稻壳对铜、铅、铬、镉和锌等重金属和油脂有很好的吸附作用。稻壳来源丰富、价格低廉,可以大大降低废水的处理成本,在处理污水方面有较大的发展前景。本文在查阅国内外相关文献的基础上,从稻壳的理化性质展开,探讨了其吸附的改性方法及其在废水处理中的吸附机理。Water pollution was becoming more and more common and a serious threat to human health,especially for wastewater containing oil and heavy metal ions,and the purification of these wastewaters was imminent.Research and studies had found that modified rice hulls had a good adsorption effect on heavy metals such as Cd(III),Pb(II),Cr(III),Cu(II)and Zn(II)ions.With abundant sources and low prices,rice husk could an greatly reduce the cost of wastewater treatment and had greater prospects for development in treating wastewater.In this paper,based on a review of relevant literature at home and abroad,the physicochemical properties of rice husk were developed to explore the modification method of its adsorption and its adsorption mechanism in wastewater treatment.
