铬渣污染场地污染状况研究与修复技术分析

选取某一化工厂铬渣堆放场地作为典型铬渣污染场地,对其钻孔并采集不同深度土壤和地下水样品进行分析。研究发现，该铬渣污染场地存在很严重的土壤和地下水污染。污染物地表扩散较小，剖面扩散很严重，污染深度达6 m，不同特性土壤对六价铬的截留作用不同。在此基础上，归纳总结了国外常用铬渣污染场地修复治理技术的优缺点，并提出具体污染场地修复技术的选取应该根据勘探情况选择合适的某些技术组合。

Study on pollution characteristics of contaminated sites with chrome and discussion on common remediation technologies

One typical chrome residue contaminated site was selected according to certain methodology. The polluted site wae analyzed by drilling and sampling soils and groundwater in different deepness, and it was found that the soil and groundwater were polluted by chromium (VI).The deepest chrome (VI) polluted soil is 6 meter underground. The concentrations of chromium (VI) in different soils are different. The typical remediation technologies for chrome residue contaminated sites are put forward.
