摘　　要：提出了在采用活性污泥法处理草浆中段废水时,宜采用推流式和完全混合式相结合且具备缺氧、好氧功能的设计工艺,并指出采用该工艺适合草浆中段废水的特点并具有处理效率高、能耗低、有效抑制活性污泥膨胀的优点;同时,给出了2种推荐工艺,供设计参考。A process combining PFR and CMAS and with the functions of Anoxic and Aerobic is suggested to be used for the treatment of the straw pulping effluent from washing, screening and bleaching stages by using activated sludge system. It has the advantage of high treatment efficiency, low energy consumption and effective restraint of sludge expansion. Finally, two processes are recommended as reference for design.
