Title
(EN) THE BIOREMEDIATION OF SOILS CONTAINING HYDROCARBON USING CALCIUM PEROXIDE
(FR) BIORESTAURATION DE SOLS CONTENANT DES HYDROCARBURES, A L'AIDE DE PEROXYDE DE CALCIUM
Abstract
(EN)
A composition and method for bioremediating a soil contaminated with polynuclear aromatic hydrocarbon or hydrocarbon derived from petroleum. The composition contains a substoichiometric amount of calcium peroxide, a nutrient source for sustaining microbial growth and a buffer as needed. According to the method the composition or the components of the composition are administered to contaminated soil to shift the microbial population and/or enzyme production in a beneficial manner for either aerobic or mixed aerobic/anaerobic bioremediation. Transport of the actives is improved through water utilization.
(FR)
L'invention concerne une composition et un procédé permettant la biorestauration d'un sol pollué par un hydrocarbure aromatique polynucléaire ou un hydrocarbure dérivé du pétrole. Ladite composition contient une dose subst÷chiométrique de peroxyde de calcium, une source de nutriments destinée à favoriser la prolifération microbienne et, si nécessaire, une solution tampon. Dans le procédé selon l'invention, la composition ou les composants de cette dernière sont administrés dans le sol pollué de façon à déplacer la population microbienne et/ou la production enzymatique de manière bénéfique pour assurer une biorestauration aérobie ou aérobie/anaérobie mixte. Le transport des substances actives est amélioré par l'utilisation d'eau.
