摘　　要：以医药中间体实际废水为对象,采用Fenton氧化法研究了pH值、反应时间和Fenton试剂用量等影响因子对实际废水处理效果的影响,考察了Fe3+、Fe2+离子分别作为催化剂在实际化工废水中的芬顿效果。结果表明:最佳处理条件为Fe2+与H2O2组成的芬顿体系,初始pH值为3,C(Fe2+)∶C(H2O2)=1∶75,C(Fe2+)=37.3mmol/L,C(H2O2)=2.8mol/L,反应40min,COD去除率可达89.85%;Fe3+与H2O2组成的芬顿体系,初始pH值为3,C(Fe3+)∶C(H2O2)=1∶53.5,C(Fe3+)=52mmol/L,C(H2O2)=2.8mol/L,反应40min,COD去除率可达89.26%。可见Fe3+可作为Fenton反应的催化剂。Taking the actual wastewater of pharmaceutical intermediates as the object,the Fenton oxidation method was used to study the influence of pH,reaction time and Fenton reagent dosage on the actual wastewater treatment effect.The effects of Fe 3+and Fe 2+ions as catalysts in actual chemical wastewater were investigated.The results showed that,the optimal initial pH value was 3;reaction time was 40 mins;the ratio of FeSO 4·7H 2O to H 2O 2 was 1∶75;the dosage of FeSO 4·7H 2O and H 2O 2 were 37.3 mmol/L and 2.8 mol/L respectively;the ratio of Fe 2(SO 4)3 to H 2O 2 was 1∶53.5;the dosage of Fe 2(SO 4)3 and H 2O 2 were 52 mmol/L and 2.8 mol/L respectively.The removal rate of COD could reach 89.85%and 89.26%respectively.Fe 3+can be used as Fenton reaction catalyst.
