| 摘 要： | 针对煤气厂土壤等高浓度多环芳烃污染土壤修复困难的现实,采用易生物降解的新型淋洗剂脂肪酸甲酯淋洗修复高浓度多环芳烃污染的土壤,同时进行了以甲醇、植物油(大豆油)作为淋洗剂的淋洗实验,比较不同淋洗剂的淋洗效果.结果证明脂肪酸甲酯对人工模拟污染土壤中蒽、荧蒽、芘、苯并(a)芘的去除率可以达到80%—95%,对煤气厂土壤中多环芳烃的去除效果也非常明显,总多环芳烃的去除率达到41%.脂肪酸甲酯的淋洗效果要优于其它两种淋洗剂. |

| Abstract: | It is difficult to remediate the manufactured gas plant(MGP)soil which contains high concentrations of polycyclic aromatic hydrocarbons(PAHs).This study used fatty acid methyl esters,which is biodegradable and novel as a washing agent,to remediate the MGP soil and the spiked soil contaminated with high PAHs.For comparison,this study also chose methanol and soybean oil as washing agents.The results show that the removal efficiencies of anthracene,fluoranthene,pyrene and benzo(a)pyrene were 80%-95% for the spiked soil.For the MGP soil,the total PAH removal efficiency was 41%.These results proved that fatty acid methyl esters were better than the other two types of washing agents for the PAHs contaminated soil remediation by soil washing method. |
| Keywords: | PAHs fatty acid methyl esters washing method remediation contaminated soil |
