农林废弃物处理重金属废水的研究进展

A review on the development of heavy metal removal by the agricultural and forestry wastes

农林废弃物来源广泛,价格低廉,且利用农林废弃物制备的生物吸附剂对水溶液中重金属离子具有良好的吸附性能,因此,受到人们的广泛关注。本文分析了农林废弃物作为生物吸附剂处理重金属废水的优势,同时介绍了农林废弃物经高温炭化或化学修饰后,其吸附重金属离子的能力显著提高的特质。这种高效生物吸附剂实现了资源的回收利用。

Agricultural and forestry wastes as bioadsorbents have been aroused great attentions due to its ad- vantages such as low cost and wide range of sources, which can be efficiently and quickly remove heavy metal ions in wastewater. In this paper, we have analyzed the advantages of Agricultural and forestry wastes and also intro- duced the modification technologies of Agricultural and forestry wastes. Agricultural waste material being highly ef- ficient and renewable source of biomass can be exploited for heavy metal remediation to improve their applicability.
