BIODEGRADATION OF OIL SLUDGE |
摘要 |
<p>A method for the biodegradation of an oil-based sludge comprising a mixture of petroleum hydrocarbons is disclosed. The method comprises forming an aqueous solution in a reactor of an oil-in-water emulsion of the oil-based sludge, bacterial culture and nutrients for the bacterial culture, the bacterial culture having the ability to grow on petroleum hydrocarbons as sole carbon source and having been isolated from a hydrocarbon contaminated soil or hydrocarbon-containing sludge or other environments rich in hydrocarbon degrading bacteria, maintaining the aqueous solution under aerobic conditions in the reactor at a temperature of at least 10.degree.C for a period of time sufficient to reduce the amount of hydrocarbon by at least 25%, and discharging aqueous solution having a reduced amount of hydrocarbons from the reactor. The method may be used on sludge containing aromatics, resins and asphaltenes.</p> |
