| 摘 要： | 通过引入油烘干损失系数λ,推导并建立含水介质中石油类含量的新计算公式,并据此对传统测量方法进行改进。结果表明,改进后的测定方法可准确测定石油污染含水介质的干固体质量和石油含量;λ值因石油的种类、含水介质的类型而异,柴油在粗砂中的烘干损失系数约为0.66,测量误差仅约为0.4%,远低于现有方法测量误差,且不受石油挥发性和含量的影响。 |
| 关 键 词： | 含水介质 石油含量 油烘干损失率 测定方法 |

| Abstract: | A new computational formula was deduced and created to calculate oil content in water-bearing medium through introducing oil dying loss ratio.The results show that this improved formula can measure dry medium solid mass and oil content in petroleum-contaminated water-bearing medium accurately.The value of oil drying loss ratio varies depending on types of oil and water-bearing media.The oil drying loss ratio in coarse sand contaminated by diesel oil is 0.66.The relative error of the new method is about 0.4%,which is far below the relative error of existing methods.Moreover,the measurement accuracy of the new method is not influenced by oil volatility and oil content. |
| Keywords: | water-bearing medium oil content oil drying loss rate meaurement technique |
