摘要
采用Fenton氧化－混凝－SBR工艺处理糠醛废水。实验结果表明：Fenton氧化－混凝预处理糠醛废水时，在废水中硫酸亚铁和过氧化氢浓度分别为57．60mmol／L和5．22mol／L、pH为2—3的条件下，废水处理后COD可达500mg／L以下；再经SBR工艺处理，水力停留时间为18h，最终出水COD去除率可达99．67％。
The furfural wastewater was treated by Fenton reagent oxidation-coagulation-SBR process. The experimental results show that： Under the conditions of FeSO4 concentration 57.60 mmol/L, H202 concentration 5.22 mol/L and pH 2 -3, the COD of the wastewater pretreated by Fenton reagent oxidation-coagulation process is below 500 mg/L; When HRT of SBR process is 18 h, the final COD removal rate of the effluent is 99.67 %.
