摘　　要：采用日光辐照H_2O_2-草酸铁氧化法处理棉浆粕废水。最佳工艺条件为:正午日光辐照10 min,废水pH5.00,废水体积150 mL,H_2O_2加入量2.0 mL,FeSO_4·7H_2O加入量0.600 0 g,K_2C_2O_4·H_2O加入量0.290 9 g。在此条件下COD由初始时的3 200 mg/L降至608 mg/L,COD去除率可达81.0%。采用气相色谱-质谱联用仪对处理前后的废水进行分析,实验结果表明该法可有效去除废水中大部分有机污染物。The wastewater containing cotton pulp dregs was treated by H2O2-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, H202 dosage 2.0 mL, FeSO4 7H2O dosage 0.600 0 g and K2C2O4 H2O 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.
