| Abstract: | Papermaking wastewater was treated by process of pre oxidation coagulating sedimentation in the study. The best experimental conditions of coagulating sedimentation method with the presence of ferric chloride?PAM as coagulant, calcium hydroxide as coagulant aids and potassium permanganate pre oxidation process were studied. The results show that pre oxidation coagulating method is better than coagulating sedimentation method, the values of COD Cr of wastewaters drop dramatically and the removal rate of COD Cr can reach 93.42%, increased by 26.8% compared with that of the process of coagulating sedimentation method. |
| Keywords: | pre oxidation potassium permanganate coagulating sedimentation papermaking wastewater |
