| Abstract: | The anaerobic/aerobic/coagulation sedimentation/aerobic process was used to treat printing and dyeing wastewater, and the removal efficiencies of COD and color under different HRT were investigated. The results show that the total removal rates of COD and color can reach more than 90% and 92% respectively, when the anaerobic HRT is 14 h and the aerobic HRT is 10.5 h. The effluent quality reaches the Ⅰ-grade discharge standard of the printing and dyeing industry. |
