Process for the biodegradation of hydrocarbons and ethers in subsurface soil by introduction of a solid oxygen source by hydraulic fracturing

摘要

A bioremediation of subsurface soil formations contaminated with hazardous wastes is achieved by hydraulic fracturing of the subsurface soil formation with simultaneous introduction of sodium percarbonate coated with polyvinylidene chloride as a solid oxygen source (SOS) for establishing colonies of the biodegrading bacteria within the fractures of the soil formation.
