摘　　要：以正十六烷为目标物,研究了生物活性炭(BAC)系统对正十六烷的吸附特征、生物吸附动力学以及活性炭的生物再生能力。研究结果表明:使用颗粒活性炭吸附正十六烷可行且具有较强的抗冲击负荷能力,等温吸附方程为a=74.088c0.49;生物活性炭法比活性污泥法对正十六烷的降解速率快,且适合长期高浓度运行使用;经过14 d培养后,吸附了正十六烷的活性炭的生物再生率可达到50.7%。The adsorption characteristics, bio -adsorption kinetics and bio -regeneration capability of activated carbon in the biological activated carbon （BAC） system was studied using hexadecane as a target. The results indicate that the method of adsorbing hexadecane by particle activated carbon is workable and its anti - shock capability for loadings is strong ; The adsorption isotherm equation is： a = 74. 088 c^0.49 ; The BAC process has higher biodegradation efficiency for hexadecane than activated sludge process, and it is suitable for application in treatment of high concentration wastewater and long - term operation ; The bio - regeneration rate of the activated carbon charged with hexadecane can reach 50.7% after 14 d of cultivation.
