【摘要】 近年来,随着城市化进程加快和工业的迅速发展,导致工业排放废弃物数量增加并且使得土壤污染加剧,其中最为严重的是重金属污染,不仅不利于经济发展而且危害到了人们的健康。生物炭作为一种新型绿色修复剂引起广泛关注,生物炭是缺氧或限氧条件下加热生物质制得的高度芳香化富含碳的固态物质。许多学者对利用生物炭改良环境污染土壤进行了各种研究。文章主要针对生物质炭修复重金属污染土壤的污染效果和治理机制进行讨论分析,最后,从当前研究中存在的不足以及对今后的研究重点和方向进行了展望。更多还原

【Abstract】 In recent years, with the acceleration of urbanization and the rapid development of industry,the amount of industrial waste discharge increases and soil pollution intensifies, among which the most serious is heavy metal pollution, which is not only harmful to economic development, but also harmful to people’s health. Biochar, as a new kind of green restorative agent, has attracted wide attention. Biochar is a highly aromatic carbon-rich solid substance produced by heating biomass under hypoxia or oxygen restriction conditions. Many scholars have conducted various researches on using biochar to improve soil pollution. This paper mainly discusses and analyzes the pollution effect and treatment mechanism of biomass charcoal remediation of heavy metal contaminated soil. Finally, the shortcomings in the current research are discussed and the future research focus and direction are prospected.更多还原
