小麦秸秆生物炭对重金属污染土壤修复机制研究进展

Research Progress on the Remediation Mechanism of Wheat Straw Biochar on Heavy Metal Contaminated Soil

近年来由于工业、矿业等可能造成重金属污染的行业发展迅速,加之对其生产废料的排放缺少严格管理,以及农作物生产中化肥的过度使用,土壤重金属污染问题已经严重影响到土壤质量以及粮食安全,成为了当下环境治理中不可忽视的一个因素。而生物炭作为新兴的土壤重金属处理工艺,凭借其对土壤中重金属离子的吸附作用,以及低廉的制备价格等优势,展现出了巨大的应用潜力和发展前景,成为了土壤重金属污染问题治理和修复方面的研究热点。

In recent years, due to the rapid development of industries such as industry and mining that may cause heavy metal pollution, coupled with the lack of strict management of their production waste emissions, and the excessive use of fertilizers in crop production, the problem of soil heavy metal pollution has seriously affected soil quality and food security, becoming a factor that cannot be ignored in current environmental governance. As an emerging soil heavy metal treatment process, biochar has shown enormous application potential and development prospects due to its adsorp-tion of heavy metal ions in the soil and its low preparation price. It has become a research hotspot in the treatment and remediation of soil heavy metal pollution.
