摘　　要：文章中的案例涉及上海市某重金属砷污染地块,根据前期调查结果,砷最大超标倍数0.83倍,污染深度1.2 m,污染方量为301.2 m^(3)。选择异位化学淋洗技术对该地块开展修复。在正式施工前,通过小试和中试试验确定了修复药剂投加量。修复工程完成后,土壤经效果评估检测达到修复目标。施工过程中未发生二次污染,该工程的顺利完成为处理其他类似项目提供了宝贵的经验。The case in this paper involves a heavy metal arsenic contaminated plot in Shanghai.According to the previous investigation results,the maximum arsenic multiple was 0.83 times,the pollution depth was 1.2 m,and the amount of contaminated square was 301.2 m^(3).The ectopic chemical leaching technology was selected to repair the block.Before the formal construction,the dosage of repair agent was determined by pilot and pilot tests.After the completion of the restoration project,the soil was evaluated and tested to achieve the restoration target.No secondary pollution occurred in the construction process,and the successful completion of the project provides valuable experience for dealing with other similar projects.
