某电镀企业污染土壤原位修复小试研究

A trial study of soil in situ restoration in an electroplating enterprise

本小试采用BCR法分析了污染土壤中重金属赋存形态,并对淋洗药剂进行了筛选。研究表明污染土壤中重金属60%以上为弱酸提取态,采用盐酸-柠檬酸-Fe2+作为淋洗剂能达到修复目标要求。

BCR method was used to analyze the morphology of heavy metals in contaminated soil,and the washing agent was selected.The results show that more than 60 % of the heavy metals in contaminated soil are weak acid extraction,and the use of hydrochloric acid-citric acid-Fe2+ as a eluent can achieve the repair goal.
