摘要
目前,腐植酸对污染土壤的修复作用已经引起了人们的广泛关注。本文在介绍了腐植酸来源及其结构特点的基础上,论述了腐植酸在土壤改良、重金属污染及有毒有机污染物污染土壤修复等方面的作用。其中,腐植酸对土壤的改良作用主要包括改良土壤结构、改良盐碱地以及提高土壤肥力等;腐植酸对重金属和有毒有机污染物污染土壤的修复作用主要包括腐植酸对重金属和有机物的吸附沉淀作用、氧化还原作用以及腐植酸能够促进土壤微生物对有机污染物的降解等。最后,讨论了腐植酸在土壤修复中需要进一步加强研究的方面,为腐植酸在土壤修复中的应用提供重要参考。
Nowadays, the effect of humic acid on soil restoration has been concerned widely. In this paper, based on brielfy introducing the sources of humic acid and its structural characteristics, the role of humic acid, the restoration of heavy metal contaminated soil and the restoration of toxic-organic pollutants contaminated soil in soil improvement were discussed. Soil improvement of humic acid includes soil structure, saline-alkali and fertility. The restoration of humic acid on the toxic organic pollutants contaminated in soil mainly includes adsorption, precipitation, oxidation and promoting microbial degradation of organic pollutants. Finally, the paper discussed the application of humic acid on soil restoration and further study of humic acid, that providing important reference for the application of humic acid on soil restoration.
