摘要
生物吸附法是一种正在迅速发展的废水处理方法。为了探讨农业废弃物作为生物吸附剂处理重金属废水的研究及利用现状,本文结合目前国内外研究进展,综述了花生壳作为吸附剂的吸附机制、表征吸附过程的吸附模型、热力学参量等工作,分析影响吸附过程的主要因素,对材料再生和金属回收等研究工作进展进行了总结,为进一步提高重金属去除效率和农业废弃物资源化提供理论指导,并对今后农业废弃物应用于处理重金属废水方面的研究重点提出了建议。
Biosorption process is a new and thriving method for dispose wastewater. To discuss the research and the status quo of the utilization of agricultural residue as bioadsorbent to remove heavy metal ions from aqueous effluents, upon the research progresses at home and abroad, this paper describe the adsorption mechanism, adsorption model and thermodynamic parameters of peanut shells as biosorbent, and analyze main influence factors of biosorption process, it＇s regeneration and the recycle of heavy metal ions from the peanut shells are summarized. We provided theoretical guidance for improving the removal efficiency of heavy metal ions and the recycling of agricultural residue. In addition, some advises for key research on agricultural residue dispose wastewater contaminated by heavy metal ions was proposed.
