摘要:

用微波-Fenton氧化法深度处理焦化废水,研究了微波处理时间、微波功率、FeSO4投加量、H2O2投加量、H2O2投加次数和pH值的影响。实验确定的最佳工艺条件为:废水pH为3,FeSO4投加量为300mg/L,H2O2总投加量为900mg/L,H2O2分3次投加,微波功率500W,温度设为50℃,反应时间为30min。废水浊度、色度和COD去除率分别为97.59%、95.62%、86.21%。处理后的废水澄清透明,剩余COD为50.34mg/L,浊度、色度和COD达到工业回用水标准。

Abstract:

This paper studies the influencing factors such as microwave processing time,microwave power,FeSO4 dosing amount,H2O2 dosing amount,H2O2 dosing times and pH value during coking wastewater treatment by Microwave-Fenton oxidation.The optimum process conditions are determined by the experiment:pH value of wastewater:3,FeSO4 dosing amount:300mg/L,H2O2 total dosing amount of H2O2:900mg/L,H2O2 dosing times:3,microwave power:500W,temperature:50℃,reaction time:30min.the removal rate of turbidity,chroma and COD are 97.59%,95.62% and 86.21% respectively.The wastewater after treatment is clear,and the remaining COD is 50.34mg/L.The turbidity,chroma and COD meet the requirement of industrial recirculating water standard.
