Color-producing chemicals emitted from many sources, such as textile or dye manufacturing industries, are a significant concern worldwide. The present study focuses on the electro-peroxone (EP) process for decolorizing a synthetic azo dye, C.I. Reactive Black 5 (RB5). Findings suggest that the EP process is more effective for dye degradation than ozonation and electrolysis. The EP process resulted in 100% decolorization after 60 min of contact time under optimum testing conditions such as pH 7, applied current 300 mA, and sulfate concentration 3.55 g L. Based on the findings of the primary investigation, EP treatment of real textile effluent was carried out and 2 h of EP treatment resulted in 99% decolorization and 74%total organic carbon (TOC) removal. As an outcome, the EP process can treat textile wastewater in a cost-effective and environmentally friendly manner.
许多来源排放的产生颜色的化学物质，如纺织或染料制造行业，是一个全球性的重大问题。本研究集中在电过氧（EP）工艺对合成偶氮染料 C.I. 活性黑 5（RB5）的脱色作用。研究结果表明，EP 工艺在降解染料方面比臭氧氧化和电解更有效。在最佳测试条件下，如 pH 值 7、施加电流 300 mA 和硫酸盐浓度 3.55 g/L，接触 60 分钟后，EP 工艺可实现 100%的脱色。基于初步研究的结果，对实际纺织废水进行了 EP 处理，EP 处理 2 小时可实现 99%的脱色和 74%的总有机碳（TOC）去除。因此，EP 工艺可以以经济有效的方式处理纺织废水，同时对环境友好。
