摘要:

多环芳烃(PAHs)是一种难生物降解的有机污染物,其污染土壤的高效植物修复技术研发一直是环境修复技术领域极富挑战性的研究课题。植物修复技术具有绿色低碳、经济高效、效果稳定及修复过程安全等优点,在土壤修复行业应用潜力大。禾本科植物在PAHs污染土壤修复方面具有生长周期短、生物量大、覆盖面广、根系发达、抗逆性强等优点,其对土壤中PAHs污染物的降解研究一直方兴未艾。本文探讨了禾本科植物对PAHs污染土壤的修复机理、效果及强化修复方法,阐述了禾本科植物修复PAHs污染土壤的研究现状及发展趋势。

Abstract:

Polycyclic aromatic hydrocarbons (PAHs) is a kind of organic pollutant which is difficult to biodegrade. Research and development of efficient phytoremediation of contaminated soil has always been a challenging task. Phytoremediation technology has the advantages of green and low carbon, low cost, stable effect and safe remediation process, so it has great potential in soil remediation. Gramineae has the advantages of short growth cycle, large biomass, wide coverage, developed root system and strong stress resistance in the remediation of PAHs contaminated soil, and its research on the degradation of PAHs pollutants in soil has been in the ascendant. In this paper, the remediation mechanism, effects and enhanced remediation methods of PAHs contaminated soil by Gramineae plants were discussed, and the research status and development trend of Gramineae remediation of PAHs contaminated soil were expounded.

Key words: phytoremediation, Gramineae, polycyclic aromatic hydrocarbons (PAHs), soil remediation, rhizosphere exudates
