| 摘 要： | 采用一种新的土柱淋滤方法,在不同淋滤量、污染强度和柱长条件下模拟了陇东黄土塬区自然降水对石油污染物在土壤中纵向迁移的影响.结果表明,石油类污染物迁移的深度受污染强度、淋滤量、土层深度等因素的限制.污染物在土柱中峰值出现的深度均随污染强度、淋滤量和土层深度的增加呈增加的趋势,在0~10 cm的范围内,污染物均大量存在,且石油类污染物在土壤中的纵向迁移规律与污染强度、淋滤量、柱长等众多因素有关,即淋滤量越大污染物越容易发生迁移,污染强度越高迁移深度越大,土层越深迁移越容易实现. |

| Abstract: | A new soil column-leaching test is applied to simulate the effects of natural precipitation on the petroleum's vertical migration in soil of the Longdong loess plateau region, considering different conditions of infiltration of water, intensity of petroleum pollution and column's length. The experimental results indicate that the depth of the petroleum contaminants'transport is limited by several factors of the intensity of petroleum pollutants, leaching volume and the depth of soil layer. The depth of the contaminant's maximum performance increases significantly with the increasing of petroleum pollutants contents and intensity, and the depths of the columns. A large number of contaminants mostly exist in soil within 0~10 cm. |
| Keywords: | petroleum pollutants loess plateau transport performance leaching process modeling test |
