摘要
文章通过对某铬盐厂铬污染土壤进行原位修复技术试验研究,根据地块的客观情况选用水平井原位联合修复技术,即原位淋洗技术和原位化学还原技术在地块进行中试试验研究。试验结果表明:采用水平井原位联合修复技术修复后土壤总铬含量低于11250mg/kg,达到修复目标。
In this paper,the experimental study of the technology for in-situ remediation of chromiumcontaminated soil was carried out in a chromate plant.According to the objective circumstances of the plot,the technology for in-situ combined remediation via horizontal well was selected and used,i.e.,the in-situ leaching technology and the in-situ chemical reduction technology were selected for the pilot scale test in the plot.The test results showed that the total chromium content in the soil was lower than 11,250mg/kg after the soil remediation based on the technology for in-situ combined remediation via horizontal well,and the remediation target was achieved.
