Abstract

Industrial effluents are produced in large quantities in underdeveloped nations, where they cannot be handled using conventional treatment techniques. In this study, hydroxyl radicals (HO^•) were successfully generated for the treatment of industrial wastewater represented in TOC removals by combining a ferrous catalyst with hydrogen peroxide in the Fenton reaction. The effects of operating conditions of pH, ferrous dose, H₂O₂ dose, time, and initial TOC concentration were studied for the Fenton process and different operating parameters were studied for the coagulation process to optimize and control the removal efficiency. The results showed that Fenton oxidation processes are able to reduce about 86 % for initial TOC level of 2000 and 95 % for initial TOC level of 400 after using 0.15 g/L ferrous dose, 10 mL/L of 30 % H₂O₂ for 30 min at acidic pH 4. Finally, this study recommends removing organic materials from industrial effluent using the Fenton oxidation method.

利用Fenton反应去除工业废水中的总有机碳(TOC)

工业废水在不发达国家大量产生，无法用传统的处理技术处理。在本研究中，在Fenton反应中，通过亚铁催化剂与过氧化氢结合，成功地产生了羟基自由基(HO•)，用于处理以TOC去除为代表的工业废水。研究了pH、亚铁剂量、H2O2剂量、时间和初始TOC浓度对Fenton工艺的影响，并研究了不同操作参数对混凝工艺的影响，以优化和控制混凝工艺的去除率。结果表明，在酸性pH为4的条件下，当亚铁浓度为0.15 g/L, H2O2浓度为30 %，H2O2浓度为10 mL/L，氧化时间为30 min时，Fenton氧化工艺对初始TOC水平为2000时可降低约86 %，对初始TOC水平为400时可降低约95 %。最后，本研究建议采用Fenton氧化法去除工业废水中的有机物质。

期刊介绍： Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
