Pulping and papermaking wastewater has been treated by PAFR-modified oxidation ditch-advanced oxidation process. There was an automatic,efficient,pulsing water distributor in the PAFR which merely consumes part of the potential energy and has no accessory equipment,such as diving agitator,etc. The sludge and water in the reactor should be mixed adequately. Modified oxidation ditch uses an integrated process“ABR+Carrousel oxidation ditch”which prevents sludge from bulking effectively. The whole technological process and main structure are intro-duced and the problems existed in the debugging process of the operation are analyzed and their solutions are put forward. Actual operation results show that the combined process system runs stably,and its effluent COD,BOD,and SS are less than or equal to 70,20,and 30 mg/L,respectively.
