Abstract
Provided is a method for disposing of contaminated deposit soil and recycled reclamation soil using the same and, more specifically, a method for disposing of contaminated dredged soil, the method comprising the steps of: seeding a mixed strain NIX51 (KACC81038BP) in the contaminated dredged soil to primarily dispose of contaminated materials in a bioreactor; and washing the degraded soil, which has been primarily disposed of, with a washing solution containing at least one selected from the group consisting of citric acid, oxalate, carbonic acid (H2CO3), and nitric acid, to secondarily dispose of heavy metals.
Claims9
A method for treating contaminated deposit soil, the method comprising:
- a first treatment involving inoculating a mixed strain NIX51 (KACC81038BP), which consists of Pseudomonas sp. BJ10, Pseudomonas sp. T18, Pseudomonas sp. E41, Pseudomonas sp. DJ19, Rhodococcus sp. PHEN3, Achromobacter sp. A-1, Pseudomonas sp. 2J and Pseudomonas sp. UI2, in the contaminated deposit soil to treat an organic contaminant in a bioreactor;
- and
- a second treatment involving washing the treated deposit soil with a washing solution comprising at least one selected from the group consisting of citric acid, oxalate, carbonic acid (H2CO3) and nitric acid to dispose of a heavy metal,
- wherein the organic contaminant is at least one multi-contamination selected from the group consisting of oil, total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbon (PAH), nutritive salts, and trichloroethylene (TCE).
