| 摘 要： | 将解吸分为平衡解吸和完全解吸两种类型，对水环境中含油泥沙上油分子的解吸特性进行了研究，通过试验，分析了解吸平衡时的吸附等温线及平衡解吸量随清水解吸液用量变化的规律，同时也对含油泥沙发生完全解吸时的最大解吸量和极限残留量进行了研究，并得出了它们随泥沙粒径变化的规律。

| Abstract: | Desorption of oil on sediment was classified into equilibrium and completion desorptions. Several physical conceptions were defined to describe the desorption characteristic. They are equilibrium desorption content,maximum desorption contend and limit remnant content. For the equilibrium desorption,the adsorption isotherms were determined and the effect of water consumption on the equilibrium desorption content of oil were studied. For completion desorption,the maximum desorption content and limit remnant content were analyzed,and the relations between them and the particle size of sediment were revealed. |

| Keywords: | oily sediment equilibrium desorption completion desorption |
