  • 摘要: 对含吡啶有机废水进行分类收集，分质处理，确定了蒸发脱盐-微电解-芬顿氧化预处理工艺路线。实验表明，蒸发脱盐阶段，pH值为5时，COD去除率达62.77%；微电解阶段，pH值为4、反应时间为2.5 h时，COD去除率达24.49%；Fenton试剂氧化阶段，pH值为4，30%H2O2投加量为3.5 ml/L，Fe2+与H2O2摩尔比为1：20，反应时间为2.5 h时，COD去除率达30.41%。经预处理，废水B/C比从0.075上升至0.48，3种特征吡啶的去除率均达到95%以上。
    Abstract: Organic wastewater containing pyridines was collected by source separation and was treated by different processes. The pretreatment process route was as follows: evaporative desalination-micro electrolysis-Fenton oxidation. The results indicated that in the evaporative desalination period, the COD removal rate was 62.77% when the pH was 5; in the micro electrolysis period, the COD removal rate was 24.49% when the pH was 4 and the reaction time was 2.5 h; in Fenton oxidation period, the COD removal rate was 30.41% when the pH was 4, the dosing quantity of 30% H2O2 was 3.5 mL/L, the molar ratio of Fe2+ to H2O2 was 1:20, and the reaction time was 2.5 h. After pretreatment, the value of BOD5/COD was up to 0.48 from 0.075, the removal rates of the three kinds of particular pollutants were all above 95%.
