The objective of this study was to investigate the application of advanced oxidation processes (AOPs) to the treatment of wastewaters contaminated with hydrocarbon oil. Three different oil-contaminated wastewaters were examined and compared: (i) a 'real' hydrocarbon wastewater collected from an oil refinery (Conoco-Phillips Whitegate refinery, County Cork, Ireland); (ii) a 'real' hydrocarbon wastewater collected from a car-wash facility located at a petroleum filling station; and (iii) a 'synthetic' hydrocarbon wastewater generated by emulsifying diesel oil and water. The AOPs investigated were Fe(2+)/H(2)O(2) (Fenton's reagent), Fe(2+)/H(2)O(2)/UV (Photo-Fenton's reagent) which may be used as an alternative to, or in conjunction with, conventional treatment techniques. Laboratory-scale batch and continuous-flow experiments were undertaken. The photo-Fenton parametric concentrations to maximize COD removal were optimized: pH = 3, H(2)O(2) = 400 mg/L, and Fe(2+) = 40 mg/L. In the case of the oil-refinery wastewater, photo-Fenton treatment achieved approximately 50% COD removal and, when preceded by physicochemical treatment, the percentage removal increased to approximately 75%.
本研究旨在探讨高级氧化工艺（AOPs）在处理含烃油废水方面的应用。考察并比较了三种不同的含油废水：（i）从爱尔兰科克郡康诺克菲利普斯怀特盖特炼油厂收集的“实际”烃类废水；（ii）从位于加油站的洗车设施收集的“实际”烃类废水；和（iii）通过乳化柴油和水生成的“合成”烃类废水。所研究的 AOPs 为 Fe(2+)/H(2)O(2)（Fenton 试剂）和 Fe(2+)/H(2)O(2)/UV（光 Fenton 试剂），它们可作为传统处理技术的替代方法或与之结合使用。进行了实验室规模的分批和连续流动实验。优化了光 Fenton 工艺的参数浓度以最大程度地去除 COD：pH = 3、H(2)O(2) = 400mg/L 和 Fe(2+) = 40mg/L。对于炼油厂废水，光 Fenton 处理可实现约 50%的 COD 去除率，而在进行物理化学处理之前，去除率增加至约 75%。
