摘要

[Problem] To provide: a treatment method for reforming a resource-substance-derived organic phase substance by removing heavy element species from said organic phase substance under mild environmental conditions; a method for collecting the removed heavy element species; a method for collecting other useful substances; heavy element species and reformed organic phase substances produced by using said methods; a device and a plant that use said treatment methods; and a means for reusing the substance(s) used in said treatment method(s) and said plant. [Solution] Disclosed is an organic-phase-substance treatment method for extracting or precipitating heavy element species from an organic phase substance into an aqueous phase by: causing an organic phase substance that includes at least an organic component derived from one or more substances selected from crude oil, bitumen, tar, residual fuel oil, petroleum residue oil, oil sand, tar sand, asphaltene, fossiliferous strata, coke, oil shale, and coal to coexist with an aqueous phase; and bringing the product resulting from the coexistence of said organic phase substance and said aqueous phase into contact with a halogen-containing chemical substance or the like. Also disclosed are a plant therefor, and substances collected by using said method.
