摘要
针对当前因工业生产活动以及其他多种因素所引发的土壤重金属污染问题日益严峻的现状,采取有效的措施进行土壤修复工作显得尤为迫切。在众多修复技术中,微生物修复技术凭借其高效性、环境友好性以及经济可行性,在土壤污染治理领域脱颖而出,受到了广泛的关注与研究。简要介绍了重金属污染土壤现状及微生物修复的机理,并综述了近年来重金属污染土壤修复领域的热点技术研究进展,特别是那些展现出巨大潜力的微生物修复技术,如微生物联合植物修复、微生物燃料电池、微生物诱导碳酸盐沉淀固定重金属、微生物胞外聚合物修复、以生物炭等为载体的微生物修复等技术,并分析了这些技术的修复机理、研究现状和应用案例,旨在整合重金属污染土壤修复领域的热点微生物修复技术,为新型微生物修复技术的发展提供一个综合性的视角。
The heavy metel pollution in soil caused by industrial production and other factors is becoming increasing severe so that it's especially urgent to take effective measures to for soil remediation.Among many remediation technologies,microbial remediation is remarkable and has great concern and research because of its attributes of ef-ficiency,environmental compatibility,and economic viability.This paper provides a succinct overview of the cur-rent state of heavy metal contamination in soil and the underlying mechanisms of microbial remediation.It also pre-sents a comprehensive review of the latest research advancements,with a particular focus on the most promising mi-crobial remediation technologies such as microbial-plant combined remediation,microbial fuel cells,microbial-in-duced carbonate precipitation fixed heavy metals,extracellular polymeric substance remediation,and microbial re-mediation by a carrier of biochar.The paper meticulously analyzes the remediation mechanisms,current research status,and practical application cases of these technologies,with the objective of consolidating knowledge in the field and offering a holistic perspective for the advancement of innovative microbial remediation techniques.
