Abstract:

Furfural wastewater has been treated by combining microwave irradiation and Fenton’s reagent oxidation.The effects of influential factors, such as wastewater initial concentration, dosage of H2O2, microwave irradiation time, microwave irradiation power, pH, etc., on furfural wastewater are investigated. The results show that when the microwave irradiation power is 480 W, microwave irradiation time 4 min, dosage of H2O2（6%） 1.5 mL, dosage of FeSO₄ 0.07 g and pH=3, the COD removal rate of furfural wastewater is 90.9%. The microwave oxidation process provides a clean, simple and convenient purification method for this kind of wastewater.

Key words: furfural wastewater, microwave irradiation, Fenton’s reagent, wastewater treatment

摘要：

采用微波与Fenton试剂联合处理糠醛废水, 分别考察了废水初始浓度、双氧水用量、微波辐射时间、微波辐射功率和pH等因素对糠醛废水处理效果的影响。结果表明, 在微波辐射功率为480W、微波辐射时间为4min、体积分数为6%的双氧水用量为1.5mL、FeSO₄用量为0.07g、pH=3的条件下, 糠醛废水COD的去除率达到90.9%, 此研究为处理该种废水提供了一种清洁、简便的净化方法。
