摘要
从城市污水处理厂取二沉池污泥,经过模拟的好氧生物反应器培养驯化30天,成功得到了具有降解油烟净化器吸收液中含油物质的生物膜系统。根据不同进水浓度和反应器温度试验结果可知,当进水吸收液含油物质浓度为300 mg/L时,好氧接触氧化系统温度为35℃时,吸收液的降解效率最高,出水中含油物质浓度为51 mg/L,降解效率达到83%。对其降解动力学方程进行拟合,得到其动力学参数米氏常数Km=(164.867±0.001)mg/L,vmax=(0.595±0.001)mg/(L·min)。
We got the sludge from secondary sedimentation tank of wastewater treatment plants,after 30 day's cultivation by simulating aerobic biological reactor,successfully obtained the biofilm system that could degrade the oleaginous materials of absorption solution spraying lampblack waste gas. 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 was 300 mg/L and 35 ℃,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 are obtained as Km(( 164. 867 ± 0. 001) mg·L-1) and vmax(( 0. 595 ± 0. 001)mg/( L·min)).
