摘要
综述了国内外铬污染场地修复技术的研究动态,探讨了铬污染修复技术研发的需求,重点讨论了铬污染土壤的主要修复技术如:土壤清洗技术、化学解毒技术、电动修复技术和稳定化技术等。并针对这些技术存在的不足,开发了化学解毒与稳定化联合技术,对山西某铬渣堆存场地中受污染土壤进行修复。结果表明:运用化学解毒与稳定化联合技术可以降低污染土壤中总铬和六价铬的浸出浓度,稳定效果好且能在工程实际中高效应用。
The present and ongoing researches and application of chromium contaminated site remediation technologies were reviewed in China and abroad. A developmental need was discussed in chromium remediation technology and soil washing technology,chemical detoxification technology, electrokinetic remediation technology and stabilization technology were focusesed on. For the deficiency existing in these remediation technologies,the combination of 'chemical detoxification and stabilization technology ' was developed and applied in chromium-polluted soil from Shanxi. The results showed that the leaching concentration of total chromium and hexavalent chromium was lowered. This illustrates the combination technology of'chemical detoxification and stabilization'had a good stabilizing effect on remediation for the chromium contaminated site and could be efficiently applied in engineering practice.
