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.
