| 中文摘要: |
| 植物修复是一种环境友好、易操作且具有经济效益的土壤污染修复技术，其可用于土壤原位修复，但修复后会产生含大量重金属的植物，对修复植物的处置成为亟待解决的科学问题。本文对现有的修复植物处置方法进行了综述，如焚烧法、热解法、热液改质法等，探讨了各种方法的优缺点以及目前研究存在的问题，并对其中的热解法与热液改质法的未来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处置方法与资源化利用提供依据与参考。 |
| 英文摘要: |
| Phytoextraction is an environmentally friendly and in-situ remediation technology for removal of heavy metals from contaminated soils, with the advantages of easy operation and economic benefits. Proper disposal of polluted plants after phytoextraction needs to be further scientifically studied and developed. This paper reviews the current disposal technologies for heavy metal-polluted plants, such as incineration, pyrolysis, and hydrothermal upgrading and discusses the advantages and disadvantages of each method. Future research on pyrolysis and hydrothermal upgrading technologies is envisioned, which may provide a strong basis and reference for rational selection and recycling of disposal technologies in practical applications. This would promote future research development of disposal technologies for polluted plants from phytoremediation of soil contaminated by heavy metals. |
