| Abstract: | The wastewater containing cotton pulp dregs was treated by H_2O_2-ferric oxalate oxidation process with sunlight irradiation. The optimum process conditions are as follows: irradiation time 10 min with midday sunlight, wastewater pH 5. 00, wastewater volume 150 mL, H_2O_2 dosage 2.0 mL, FeSO_4 7H_2O dosage 0.600 0 g and K_2C_2O_4 H_2O dosage 0.290 9 g. The wastewater COD is decreased from 3 200 mg/L to 608 mg/L and the COD removal rate is 81.0% under these conditions. The treated wastewater and non-treated wastewater were analyzed by GC-MS. The results show that the most organic contaminants in the wastewater can be removed effectively. |
