| Abstract:The advanced treatment of papermaking-reconstituted tobacco slices effluent by single coagulation process, single Fenton oxidation process and coagulation-Fenton process was carried out, and the optimal conditions of coagulation and oxidation were determined. Experiments found that the result of wastewater treatment using single coagulation process or single Fenton process could not meet the national emission regulations. However it was found that coagulation-Fenton process with the conditions of initial pH value was 8, PAC dosage was 1.35 g/L, PAM dosage was 3.6×10-3 g/L in coagulation process, and initial pH value was 3, H2O2 dosage was 15 mmol/L, FeSO4 dosage was 7.5 mmol/L, in the Fenton process the CODCr and color of the effluent could be lower than 81 mg/L and 49.2 C.U. respectively, which could meet the national emission standards. |
