The practical full-scale test showed that the washing treatment of the petroleum contaminated soil (approximately 70,000 mg/kg ) containing heavy petroleum fractions improved it to be suitable for bioremediation. The oil removal rate of three types of pre-treatment (water washing treatment by mechanical plant, in situ washing treatment, and vacuum aspiration treatment ) were 90%, 80%, and 50%, respectively. |
