| 摘 要： | 根据某化工厂铬渣污染场地初步污染调查结果,选择污染场地中受污染砂土作为研究对象,进行了形态分析与酸淋洗试验研究.结果表明,砂土中铬主要以酸溶态铬为主,最高达96%.在形态分析的基础上,选择2%～6%的盐酸作为淋洗剂,进行淋洗可行性研究,研究结果表明,淋洗后可使铬总量达到加利福尼亚州土壤总铬限值,总铬去除率达到88.8%～92.6%.

| Abstract: | Based on the investigation of the site polluted by the chromium residue in a chemical factory,the polluted sandy soil was selected as remedial object.Morphology analysis of chromium and acid leaching experiments were done and the results show that the acid solution chromium is the main morphology and the highest proportion can reach 96%.In light with the results of morphology analysis,acid flush technology was selected as sandy soil remediation process.The test results show that 2 percent to 6 percent hydrochloric acid can make the content of chromium in the sandy soil meet the remedial standard of California.The removal rate of total chromium can reach 88.8% ～ 92.6%. |
