摘要
随着社会的发展与人民生活的需求,染料被广泛应用于纺织、印刷与皮革加工等工业生产当中,因而产生了大量富含染料的印染废水。其中,偶氮染料在染料生产与使用市场中占比最高,亟需高效的技术来消除此类毒害污染物。本文以橙黄G为例,深入对比分析了UV/PMS和UV/H_(2)O_(2)两种紫外高级氧化工艺对偶氮染料废水的降解与矿化效能。结果表明,中性条件下UV/PMS工艺更具优势,当氧化剂浓度为5 mmol/L,OG质量浓度为50 mg/L时在20 min内能去除100%的橙黄G与46.4%的TOC。
With the development of society and the needs of the people,dyes are widely used in textile,printing and leather processing industries,generating a large amount of dye-rich wastewater.Among them,azo dyes account for the highest proportion in the dye production and use market,and efficient technologies are urgently needed to eliminate such toxic pollutants.In this paper,the degradation and mineralization efficacy of two UV advanced oxidation processes,UV/PMS and UV/H_(2)O_(2),on azo dye wastewater were compared and analyzed using Orange G as an example.The results demonstrated that the UV/PMS process was more advantageous under neutral conditions,removing 100%of the pollutants and 46.4%of the TOC in 20 min when the oxidant concentration was 5 mmol/L and the OG concentration was 50 mg/L.
