  • 摘要: 采用Fe2+活化PS高级氧化-离子沉淀-V型砂滤组合工艺对模拟印染废水进行深度处理。以AO7为模型污染物,模拟COD约100 mg/L的废水,考察了PS、FeSO4投加量和摩尔比对COD去除率、体系剩余SO42-浓度和SS去除率的影响。结果表明,该组合工艺能有效处理AO7废水,当PS:Fe2+:AO7摩尔比为30:15:2时,COD去除率可达最大的80.6%,处理成本5元/m3;当PS:Fe2+:AO7摩尔比为30:15:4时,COD去除率可达77.6%,SO42-去除率高达60.6%,出水SO42-浓度124.4 mg/L,处理成本2.7元/m3;当PS:Fe2+:AO7摩尔比为30:20:8时,COD去除率可达64.7%,SO42-去除率达42.4%,出水SO42-浓度110.5 mg/L,SS3。组合工艺中高级氧化塔为COD去除的关键环节;离子沉淀池可以有效去除反应过程中产生的SO42-。
    Abstract: This article presents the combined process of ferrous ion-activated persulfate-ion deposition V-shaped sand filtration as an approach to investigate simulated textile wastewater. Acid orange 7 (AO7) was chosen as the model contaminant to simulate dye wastewater with 100 mg/L COD. The influence of the dosage of persulfate (PS) and ferrous (Fe2+) ions and their molar ratio on COD, sulfate ion, and SS removal was studied. The results indicate that AO7-dyed wastewater could be effectively treated by the combined process. When the PS:Fe2+:AO7 molar ratio was 30:15:2, the removal rate of COD reached a maximum of 80.6% with a treatment cost of 5 yuan/m3. When the PS:Fe2+:AO7 molar ratio was 30:15:4, the removal rates of COD and SO42- reached 77.6% and a maximum of 60.6%, respectively. The effluent concentration of the sulfate ion was 124.4 mg/L, and the treatment cost was 2.7 yuan/m3. When the PS:Fe2+:AO7 molar ratio was 30:20:8, the removal rates of COD and SO42- were 64.7% and 42.4%, respectively. The effluent concentration of the sulfate ion was 110.5 mg/L; and the treatment cost was the lowest at 1.5 yuan/m3. The AOP reaction was the dominant COD removal component in the combined process. Additionally, an ion deposition reaction could effectively remove SO42- produced by AOPs.
