摘要
采用微波强化Fenton氧化法处理高浓度医药中间体废水,分别考察初始pH、双氧水(30%)投加量、FeSO4.7H2O投加量、微波功率和反应时间等因素对医药中间体废水处理效果的影响.结果表明:在初始pH为4、双氧水投加量为5 mL/L、FeSO4.7H2O投加量为3 g/L、微波功率为300 W、反应7 min的条件下,处理500 mL医药中间体废水,其化学耗氧量(COD)去除率达89.7%.反应动力学研究表明,微波强化Fenton氧化法处理医药中间体废水符合一级反应动力学模型,反应半衰期为2.60 min.
High concentration pharmaceutical intermediate wastewater was treated by microwave-assisted Fenton oxidation process.The influential factors,such as initial pH value,H2O2（30%） dosage,FeSO4·7H2O dosage,microwave power,and reaction time on chemical oxygen demand（COD） removal were investigated.The optimal conditions were determined as follows： initial pH of 4,the H2O2 dosage of 5 mL/L,the FeSO4·7H2O dosage of 3 g/L,microwave power of 300 W,and reaction time of 7 min.Under the optimum conditions,the COD removal rate could reach 89.7% when treating 500 mL of the wastewater.Kinetics study indicated that the degradation process accorded with the first-order reaction kinetics model,and the half life was 2.60 min.
