Abstract

Tank-cleaning oil sludge containing about 68.59 % saturated hydrocarbon and 14.93 % aromatic hydrocarbon was degraded by P. aeruginosa NY3 in this study. The results showed that, the degradation of oil sludge by P. aeruginosa NY3 was preferred under aerobic conditions, and sufficient dissolved oxygen could greatly enhance the degradation efficiency of oil sludge. Under conditions that 10% oil sludge (equivalent to 25g/l oil) were added in biodegradation medium, and supplemented with proper concentration of RL, pyruvic acid or Mg2+, the degradation and transformation efficiency of oil sludge could be greatly accelerated. Under optimal conditions, the degradation rate of hydrocarbons in oil sludge could reach above 90% within 7days. The results of the present study showed the excellent ability of P. aeruginosa NY3 in degrading oils contained in tank-cleaning oily sludge under optimal conditions.
