| Abstract: | hnproved oxidation ditch process and jet aeration system was adopted to treat washing and bleaching effluent in a paper mill in Gansu. Enlarging of productive capacity and unstable production result in the problems of uneasy control of chemical dosage in shallow air flotation system, great quantities of foam occurring in aeration tank and sludge floating in the secondary sedimentation tank, which were solved by increasing sludge discharge in the early stage, increasing supply of dissolving oxygen, decreasing sludge reflux ratio to get ideal treating effect. |
