摘　　要：目前,我国土壤重金属污染依然比较严重,给人体健康造成巨大的威胁。本文总结了国内外重金属污染土壤修复手段及资源化途径,研究了轻度重金属污染土壤制砖工艺,分析了该工艺产污节点,通过重金属元素平衡探究轻度重金属污染土壤中重金属的去向,并对产品的浸出毒性与相关国家标准进行对比。结果表明,该工艺对轻度重金属污染土壤的资源化效果十分可观,能够产生极大的社会效益、经济效益和环境效益。At present,China’s soil heavy metal pollution is still relatively serious,posing a huge threat to human health.This paper summarizes the remediation methods and resource utilization methods of heavy metal contaminated soil at home and abroad,studies the brick making process of light heavy metal contaminated soil,analyzes the pollution-producing nodes of this process,explores the whereabouts of heavy metals in the light heavy metal contaminated soil through the balance of heavy metal elements,and compares the leaching toxicity of the product with the relevant national standards.The results show that this process has a considerable resource utilization effect on light heavy metal contaminated soil,and can produce great social,economic and environmental benefits.
