农林废弃物生物吸附剂处理重金属废水的研究进展

Research progress on the treatment of heavy metal wastewater by agroforestry waste biological adsorbent

介绍了重金属废水的来源与危害、传统的处理方法以及常见的农林废弃物,并阐述了吸附机理。农林废弃物用于处理重金属废水实现了资源的综合利用,具有广阔的工业前景。农林废弃物是数量巨大的农业和林业的副产品,具有可再生和再生周期短等特点,且能交联产生活性基团,并且能快速、高效地去除水中的金属离子,因此,利用农林废弃物制备生物吸附剂吸附水中的重金属备受关注。

This paper introduces the sources and harms of heavy metal wastewater,traditional treatment methods and common agricultural and forestry wastes,and expounds the adsorption mechanism.Agricultural and forestry wastes used to treat heavy metal wastewater realize the comprehensive utilization of resources and have broad industrial prospects.Agroforestry waste is a huge amount of agricultural and forestry by-products,with the characteristics of renewable and short regeneration cycle,and can cross-link to produce active groups,and can quickly and efficiently remove metal ions in water,therefore,the use of agroforestry waste preparation of biological adsorbent adsorption of heavy metals in water has attracted much attention.
