关 键 词:soil washing total petroleum hydrocarbon(TPH) benzo(a)pyrene petroleum contaminated soil soil restoration
摘 要:Petroleum contaminated soil of 24,620 cubic meters,excavated from an old railroad in Daejeon,Korea,was remediated with soil *** contents of total petroleum hydrocarbon(TPH) and benzo(a)pyrene in the soils,presumed to originated from oil-spills and wood-preservatives,respectively,turned out to exceed the legal standards;a soil washing process was adopted to remediate the contaminated soils.A soil washing plant of 40 tons/hr capacity was installed on the site and operated for three *** washing process successfully decreased the concentrations of contaminants enough to meet the legal *** water used in the washing process was reused after simple water-treatment processes,coagulation/sedimentation,which led to a zero-discharge process.
