利用农业副产物制作低成本吸附材料的研究现状与展望

Status Quo and Prospect of Research on Production of Low-Cost Adsorbents With Agricultural Byproducts

将农业副产物制作成高效的低成本生物吸附剂,用于污染水体的净化处理,具有广阔的应用前景。这一方面为资源化利用农业副产物提供了一条新途径,另一方面为水体净化提供了新的低成本吸附材料。鉴于此,近年来基于农业副产物的低成本生物吸附剂得到大量研究。该研究综述了近年来基于农业副产物的低成本吸附剂运用于废水净化处理的研究现状,着重分析了基于农业副产物的原始生物吸附材料、采用化学修饰处理农业副产物和采用物理技术处理农业副产物3种制作方法,总结了该类研究面临的问题,并对将来的研究方向进行了展望。

Being a major agricultural country in the world,China produces hundreds of millions of tons of agriculture byproducts annually,of which,however,only approximately 60％,significantly lower than that in developed countries,are used.There is still much room for exploiting the resources of agro-based byproducts.A large volume of studies have been done focusing on recycling of agro-based byproducts.Using agricultural byproducts to produce low-cost bioadsorbents intended for wastewater treatment is one topic,and moreover a promising one,which will not only offer a new approach to the exploition of resources for agricultural byproducts,but also supply with a new kind of low-cost bioadsorbent for wastewater treatment.A review of the researches in this field is presented,introducing 3 ways to produce adsorbents with agricultural byproducts.i.e.crude agricultural-byproduct-based adsorbents,chemically modified adsorbents and physically modified adsorbents,summarizing problems faced in the researches and discussing prospects of future researches.
