修复植物处置技术及重金属迁移的研究进展

Research Progress on Remediation Plant Disposal Technology and Heavy Metal Migration

为了解决重金属污染土壤的问题,采用植物修复这一环境友好且易操作的方式,可以达到使土壤中的重金属迁移进入植物的目的。为了确保修复植物的后续处理更加高效,本文对比了传统的处理方式(堆肥法、填埋法和液相萃取法)和热处理方式(气化法、焚烧法、热解法和水热液化)的优势和不足,并对修复植物未来的研究方向进行了展望,以期为今后在实际应用中合理选择修复植物的处理方法与资源化利用提供参考。

In order to solve the problem of heavy metal contaminated soil,phytoremediation was adopted to achieve the purpose of transferring heavy metals in soil into plants.In order to ensure more efficient subsequent treatment of repaired plants,the traditional treatment methods(composting,landfill and liquid phase extraction)and the heat treatment methods(gasification,incineration,pyrolysis and hydrothermal liquefaction)were compared,the advantages and disadvantages of these methods were explored.The future research direction of restored plants was prospected.
