摘要
含油污泥是炼厂及相关石化企业常见的危险废物,由于缺少相应的技术支持,企业普遍采用厂内贮存和外委处理。随着法律的日益完善,研究一条切实可行的含油污泥处理途径迫在眉睫。萃取法被认为是一种很有效的含油污泥处理方法,不仅能回收其中的油分,而且还能实现萃取剂的循环使用。总结了近年来萃取法及其与其他方法联用处理含油污泥的效果,并针对现有方法存在的不足提出了改进方向。
Oily sludge is a common hazardous waste in related petrochemical enterprises.Due to lacking of corresponding technical support,petrochemical enterprises generally store oily sludge in their own plants temporally and then entrust other companies to deal with.With the law and regulations becoming more and more strict,it is imminent to study a practical approach to treat oily sludge.The solvent extraction method is considered an effective method for treating oily sludge,which can recover oil and recycle extractant.This paper summarizes the treatment effects of combining solvent extraction method with other methods in recent years,and proposes improvement ideas to the existed treatment methods that have shortcomings.
