摘要
We got the sludge from secondary sedimentation tank of wastewater treatment plant. After cultivation by simulating aerobic biological reactor for 30 days,the biofilm system that could degrade the oleaginous materials of absorption solution spraying lampblack waste gas was successfully obtained. From different influent concentration and temperature experiments,it was shown that the degradation efficiency of the oleaginous materials was the most,when the influent concentration and the temperature of the biological contact oxidation reactor were 300 mg/L and35 ℃,especially the effluent concentration and the degradation efficiency of the oleaginous materials was 51 mg/L and 83%. The modified Michaelis-Menten equation was used to analyze the data,and the kinetics parameters were obtained： K_m=（ 164. 867 ± 0. 001） mg/L; vmax=（ 0. 595 ±0. 001） mg/（ L·min）.
