The process of biodegradation of petrochemical sludge was carried out on anaerobic expanded bed inoculated with selected strains of Desulfovibrio bacteria. Pollution in digested sludge was significantly reduced under conditions of sulphate respiration and four-day long bed operation period. The reduction of chemical oxygen demand (COD) was higher that 95%. 58% of the total amount of hydrocarbons (incl. aromatic hydrocarbons) was initially biotransformed. The examined process may be used as the first stage of biochemical degradation of sludge contaminated by fossil fuel products.
