Fenton法预处理实验室废水的实验研究

Study on Treatment of Laboratory Wastewater by Fenton Reagent

采用Fenton试剂对实验室废水进行预处理,考察了pH、H2O2投加量、FeSO4投加量、反应时间等因素,确定了最佳工艺条件。实验结果表明:H2O2投加量为8.5 mL/L,FeSO4投加量为1.6 g/L,pH为2.5,反应时间为120 min,预处理效果最好。

The process of laboratory wastewater treatment by Fenton reagent was investigated in this study. The effects of pH value, the dosage of H202 and FeSO4 and reactive time on the removal efficiency of COD were studied respectively. The results showed that： When the dosage of H2O2 was 8.5 mL/L, the dosage of FeSO4 was 1.6 g/L, the pH value was 2.5, the reactive time was 120 minutes, maximal COD removal was achieved.
