杉木锯木屑对落地机油吸附及解吸性能试验

China fir sawdust absorbing falled lubrication oil

试验使用汽机油为吸附对象,杉木锯木屑为吸油材料,按照回归正交设计方法进行试验,得到粒度、湿度和温度等因素影响木屑对机油饱和吸附量的回归方程,结果表明木屑湿度对饱和吸附量有极显著的影响;淋滤试验结果表明,木屑吸附机油程度与环境温度对机油的解吸迁移影响显著。试验结果为陆上机油泄露事故的无害化处理提供依据。

In this study,gasoline lubrication oil is used as adsorbate,while China fir sawdust used as adsorbent. Experiments are executed according to the regressive orthogonal design to find out the regressive linear equations, which shows humidity extremely influence the sawdust to absorb oil.On the natural release of the oil-polluted sawdust,experiments show that it is strongly influenced by the pollution level and temperature.The result provides a reference for disposition of failed lubrication oil.
