| 摘 要： | 强化生物通风技术对于修复因地下储油罐泄漏引起的土壤污染具有很大的应用前景。通过室内土柱模拟柴油泄漏污染土壤,从土柱中总石油烃（total petroleum hydrocarbon,TPH）剖面分布随时间的变化及降解模式角度,分析了其自然衰减和强化生物通风过程。结果表明：初始柴油浓度直接影响着各柱在自然衰减和强化生物通风过程中柱内的残余TPH平衡分布曲线的形状和浓度峰值位置;在前期自然衰减过程中（约1个月）,当土壤中的柴油浓度为5 000～40 000 mg油/kg土时,整个柱内TPH变化的主要原因是重力扩散迁移的结果;当土壤中的柴油浓度≤5 000 mg油/kg土时,其TPH的变化不仅是重力扩散迁移作用的结果,生物降解作用也存在;通风约2个月后,抽提作用对于保持土柱上部柴油浓度稳定变化的意义较为突出。

| Abstract: | Enhancing bioventing technology has great application prospects for remediating soil contamination caused by leaking underground storage tanks.In this study indoor soil column experiment was conducted.Natural attenuation of diesel oil in leaking contamination soil and the course of enhancing bioventing were analyzed from the viewpoint of the changes of total petroleum hydrocarbon(TPH) in soil column profile with sampling time and degradation pattern.The results showed that the shape of residual TPH distribu... |
