  • 摘要: 采用Fenton试剂对某染袜厂2种印染废水（印染红和印染蓝）进行处理。考察了硫酸亚铁投加量、双氧水投加量、反应时间及pH值对印染废水的色度及COD去除率的影响，通过正交实验确定了Fenton试剂处理该废水的最佳操作条件为：反应时间30 min、双氧水（30%）投加量4 mL/L、硫酸亚铁投加量300 mg/L、pH值为4左右。在最佳条件下，印染蓝废水经氧化处理后COD去除率大于80%，色度去除率95%以上；印染红废水需经絮凝预处理后再用Fenton试剂氧化处理，其脱色率达到了99.6%，COD去除率为91.2%，出水COD浓度为96 mg/L，可达标排放。
    Abstract: Fenton reagent was employed to treat two kinds of printing and dyeing wastewaters (printing and dyeing red and printing and dyeing blue). The effects of FeSO4 dosage, H2O2 dosage, reaction time and pH on removal efficiencies of chroma and COD of the wastewater were investigated. The optimal operating conditions determined by orthogonal experiments are as follows:[FeSO4] = 300 mg/L,[H2O2] = 4 mL/L, 30 min at pH=4. Under these conditions, the removal rate of COD of printing and dyeing blue wastewater was more than 80% after oxidation treatment; chroma removal rate was over 95%. Dyeing and printing red wastewater should be treated by flocculation pretreatment before being oxidized by Fenton reagent, the chroma removal rate reached 99.6%, COD removal rate was 91.2%, effluent COD concentration was 96 mg/L and can meet the national drainage criterion.
