利用高吸油树脂修复液相油性化合物污染土壤的方法

Method for Remedying Soil Polluted by Liquid Oily Compounds Using High Oil-absorption Resin

为了快速修复液相油性化合物污染土壤并避免2次污染的发生,利用高吸油树脂从土壤中将油性污染物吸附、转移出来,研究出了修复液相油性化合物污染土壤的一套工艺技术.在土壤经过前处理并与高吸油树脂充分混拌、接触的条件下,达到了将油性污染物从土壤中转移出来的效果,经过筛分及高吸油树脂脱吸、再生等工序后,高吸油树脂可以循环使用.这套工艺技术可以应用在石油开采、化工生产及运输过程中所造成的土壤污染的快速修复并避免了2次污染.

In order to rapidly remedy soil polluted by liquid oily compounds and prevent the occurrence of secondary pollution, high oil-absorption resin was used to absorb and separate oily pollutants in soil.The results show that oily pollutants are separated from soil after soil pretreatment, and fully mixing and contacting with high oil-absorption resin. The high oil-absorption resin can be used repeatedly after screening, desorption and regeneration process. and other processes after super oil-absorption resin can be recycled. This indicates that the technology can be applied to rapidly remedying soil pollution and avoid secondary pollution resulted from oil exploitation, chemical production and transportation.
