摘　　要：研究了焦化废水的三相生物流化床处理工艺中苯系物的去除特征。焦化废水苯系物中,苯为主要物种,气浮、除油以及好氧和厌氧工艺段对苯系物有较高的去除率。对苯系物在水相与污泥相中的分配系数研究表明,污泥对苯系物吸附的决定因素为苯系物的辛醇水分配系数。The removal characteristic of benzenes in three-phase biological fluidized bed treatment of coking wastewater were studied. Among the benzenes in coking wastewater, benzene is the main species, and the removal rate of benzenes is higher in the stages of air flotation, oil removal, aerobic and anaerobic processes.The study on the distribution coefficient of benzenes in water phase and sludge phase showed that the determined factor of the adsorption of benzenes in sludge is the octanol water distribution coefficient of benzenes.
