Patent

CA 2126511

There is disclosed a method of detoxifying sediment containing polynuclear aromatic hydrocarbons and petroleum hydrocarbons wherein a chemical oxidant is added to a sediment containing microbes in combination with the addition of an organic amendment to enhance natural biodegradation of the above- mentioned compounds. The method additionally provides for compaction of the sediment depth by enhanced production of methane gas as a reaction by-product.

Divulgation d'une méthode pour détoxifier des sédiments contenant des hydrocarbures aromatiques polynucléaires et des hydrocarbures pétroliers. La méthode consiste à ajouter un oxydant chimique à un sédiment contenant des microorganismes en même temps qu'un amendement organique pour améliorer la biodégradation naturelle des composés susmentionnés. La méthode permet également de réduire par compaction l'épaisseur des sédiments par production accrue de gaz méthane comme sous-produit de réaction.
