Biological Degradation of Crude Oil Refinery Sludge with Commercial Surfactant and Sewage Sludge by Co-Composting

摘要: This study determined the potential of surfactant and sewage sludge in enhancing degradation oil sludge. A mixture sludge, surfactant, was co-composted for 24 weeks laboratory. Physical chemical parameters compost were measured every four weeks. Isolated microorganisms characterized by molecular techniques. The pH all experiments remained between 8 6.4. CO2 evolution reached 5503 µg/dwt/day twenty-fourth week. dominant bacterial species Acinectobacter, Rodococcus, mycobacterium, Pseudomonas, Bacillus, Arthrobacter, Staphylococcus fungi Pleurotus, Penicillium, Aspergillus sp. TPH reduced 92% treatment, 75 81% other treatments, 44.2% control. PAH concentrations 100%. results indicate that a careful application could enhance system.
