非粮生物质吸附剂吸附水中氨氮的研究进展

摘要

非粮生物质作为一种价廉、易得、环保的吸附剂,对废水中氨氮的处理效果较好.论文简要介绍了目前废水中氨氮的处理方法及其处理现状,并着重介绍非粮生物质处理氨氮的现状;通过分析不同种类的非粮生物质在不同的改性方法下所得改性吸附剂对废水中氨氮的吸附研究,利用研究成果简述其吸附机理,并在此基础上对其未来研究前景与侧重点进行探讨.%As a kind of cheap, easily accessible and environmentally-freindly absorbent, non-food biomass is very effective in treating the ammonia-nitrogen in wastewater. This paper briefly introduced the processing method of ammonia nitrogen in wastewater treatment, focusing on the current situation of treating ammonia-ni-trogen by non-food biomass. Then, different kinds of non-food biomass were modified in various ways for am-monia-nitrogen adsorption, and the mechanism of adsorption was expounded accordingly. Based on the existing research findings,the key points and prospects of its future were presented.
