农业废弃物作为生物质吸附剂对废水处理的研究进展

摘要

The structure of agricultural wastes is loose and porous,and containing active functional groups such as carboxyl and hydroxyl,which can be used for biomass adsorption material in the field of water pollution control,these not only can be used to reduce the environmental burden but also to achieve the effect of "waste treatment".Biomass adsorption have the characteristics of low cost,high efficiency,renewable and so on.It has a broad space for development in the field of water treatment technology.Therefore,the adsorption capacity of typical agricultural wastes,such as orange peel,banana peel and grapefruit peel as biomass adsorbents on organic and inorganic pollutants in water was summarized,in order to provide some theoretical guidance for the further improvement of wastewater treatment of agricultural waste.%农业废弃物具有疏松、多孔的结构,并含有羧基、羟基等活性基团,可用作水污染控制领域的生物质吸附材料,这不仅能够减少环境负担还能达到“以废治废”的效果.生物质吸附材料具有低成本、高效率、可再生等特点,在水处理应用技术方面有广阔的发展空间.结合当前国内外研究进展,概述了以橘子皮、香蕉皮和柚子皮为代表的典型农业废弃物作为生物质吸附剂处理水中的有机和无机污染物的研究,以期为进一步研究农业废弃物在水污染控制领域的应用提供一定的理论指导.
