摘　　要：本文旨在深入研究固化稳定化修复技术、化学还原修复技术以及淋洗修复技术对铬污染土壤中六价铬的修复效果,并在实验过程中收集多种铬污染土壤样本,系统地比较不同修复技术的效率及其对土壤性质的影响。实验结果表明,固化稳定化技术能够有效地将六价铬转化为稳定形态,降低其在土壤中的迁移性;化学还原技术通过还原反应将高毒性的六价铬转化为低毒性的三价铬,减少了土壤中的六价铬含量;淋洗修复技术则通过淋洗剂的吸解作用,去除了土壤中的六价铬。The purpose of this paper is to further study the remediation effects of solidification stabilization remediation technology,chemical reduction remediation technology and leaching remediation technology on hexavalent chromium in chromium-contaminated soil,and collect a variety of chromium-contaminated soil samples during the experiment to systematically compare the efficiency of different remediation technologies and their effects on soil properties.The experimental results show that the solidification and stabilization technology can effectively convert hexavalent chromium into a stable form and reduce its mobility in soil.The chemical reduction technology converts highly toxic hexavalent chromium into low-toxicity trivalent chromium through a reduction reaction to reduce the content of hexavalent chromium in soil.The leaching remediation technology removes hexavalent chromium from the soil through the adsorption of the eluent.
