摘要：N,N-二甲基甲酰胺(DMF)作为一种万能溶剂在工业中被广泛应用,但它有毒性、难以生物降解。本文采用Fenton法处理DMF模拟废水,考察了pH、反应时间、氧化剂投加量等条件对处理效果的影响,同时探讨了Cl-和SO2-4对反应的影响。研究结果表明:处理1g/L的DMF模拟废水,最佳反应条件为:w=30%H_2O_(2)的投加量为40mL/L,pH=2.0,n(H_2O_(2))∶n(Fe2+)=3∶1,反应时间2.5h,在该条件下出水化学需氧量(COD)小于100 mg/L;Cl-对Fenton法处理DMF废水有着十分强的抑制作用,1g/L就会使出水COD由90mg/L上升到250mg/L;而SO2-4对Fenton反应的处理效果影响很小,当ρSO2-4>10g/L时有一定的促进作用。
N,N-Dimethylformamide(DMF)is a universal organic solvent in industry,while it is toxic and non-biodegradable.In this paper,Fenton oxidation was used to treat model DMF wastewater and the influence of pH,reaction time,dose of oxidation agent,as well as the effect of inorganic anions Cl-and SO42-were investigated.The experimental results showed that the optimum conditions with effluent COD<100mg/L were as follows:when the concentration of DMF was 1g/L,the dosage of 30%H_2O_(2)was40mL/L,pH=2.0,n(H_2O_(2))∶n(Fe2+)=3∶1,reacting time is 2.5h.Meanwhile,Cl-had a strong inhibition effect on Fenton oxidation:the COD of effluent increased from 90mg/L to 250mg/L with 1g/L Cl-.The effect of SO42-on the reaction was very small:with a concentration higher than 10g/L,it could accelerate the reaction to some extent.
