摘要

摘要: 对比芬顿氧化、电化学催化氧化与臭氧催化氧化3种高级氧化工艺对某酱香型白酒废水二级处理出水的处理效果，重点考察不同工艺氮素形态转化规律。结果表明，3种工艺均可降低COD并改善可生化性，其中，臭氧催化氧化综合性能最优，在pH=8~10，O₃浓度66 g/m³，V（催化剂）∶V（废水）=（0.5~1）∶1的条件下反应150 min后，COD和UV₂₅₄脱除率分别达89.50%和96.08%，废水B/C由<0.1提升至0.69，可生化性显著改善。3种工艺的氮素转化路径存在差异，臭氧催化氧化可将大部分难降解有机氮转化为NH₄⁺-N和NO₃^--N；芬顿氧化和电催化氧化则主要将有机氮转化为NH₄⁺-N，均未能实现进一步硝化。高级氧化工艺将难降解有机氮转化为NH₄⁺-N、NO₃^--N，可为“化学预氧化+生化处理”组合深度处理工艺的选择与实施提供依据。成分表征显示，二级处理出水以腐殖酸、富里酸为主，同时含有部分木质素衍生物及可能来自美拉德反应的氮杂环类物质，臭氧催化氧化对其均有良好处理效果。

Abstract: The treatment performance of three advanced oxidation processes （Fenton oxidation， electrochemical catalytic oxidation， and ozone catalytic oxidation） on the secondary effluent of a Jiang-flavor （Moutai-flavor） Baijiu wastewater treatment process was comparatively investigated， with a focus on the transformation patterns of nitrogen species. All three processes exhibited a certain capacity to degrade organic pollutants. Among them， ozone catalytic oxidation demonstrated the best comprehensive performance. Under the conditions of pH of 8 to 10， O₃ concentration of 66 g/Nm³， a catalyst-to-wastewater volume ratio of （0.5 to 1）∶1， and a reaction time of 150 min， the removal efficiencies of COD and UV₂₅₄ reached 89.50% and 96.08%， respectively. The B/C ratio of the wastewater increased from 0.1 below to 0.69， indicating a significant improvement in biodegradability. The three processes exhibited distinct nitrogen transformation pathways： ozone catalytic oxidation converted most of the refractory organic nitrogen into NH₄⁺-N and NO₃^--N； Fenton oxidation and electrochemical catalytic oxidation mainly transformed organic nitrogen into NH₄⁺-N， without further nitrification. Advanced oxidation processes converted refractory organic nitrogen into NH₄⁺-N and NO₃^--N， providing a basis for the selection and implementation of a combined “chemical pre-oxidation + biological treatment” advanced treatment process. Component characterization showed that the secondary treated effluent was mainly composed of humic and fulvic acids， while also containing some lignin derivatives and nitrogen heterocyclic substances possibly derived from the Maillard reaction， all of which were significantly degraded by ozone catalytic oxidation.
