摘要
采用Fenton试剂絮凝氧化法预处理皂素废水,考察了H2O2投加量、FeSO4·7H2O投加量、pH值和搅拌时间4个因素,研究其对废水中COD去除效果的影响,实验结果表明反应的最佳条件为:pH为4,H2O2投加量为18mL/L,FeSO4·7H2O投加量为7g/L,搅拌时间为45min,对COD的去除率可达到42.60%。
The degradation of the saponin wastewater was carried out by Fenton method, the influence of pH, H2O2 dosage, FeSO4·7 H2O dosage and stirring time was investigated to study the impact on wastewater COD removal efficiency. The experimental results showed that the optimal conditions are as follows： pH 4, H2O2 dosage 18 mL / L, FeSO4 ·7 H2O dosage 7g/L, stirring time is 45 min. Under these conditions, the removal rates of COD could reach to 42.60%.
