强化Fenton法降解含能材料废水的研究(英文)

Enhanced-Fenton Process for Degradation of Wastewater Containing Energetic Compounds

综述了能提高废水处理效率的Fenton组合工艺和类Fenton处理方法,并对超声波和微波辅助高级氧化技术处理有机废水进行了介绍。在高级氧化技术中,废水中的过渡金属离子、还原性铁粉、粉煤灰等可以作为Fenton试剂中替代亚铁离子的催化剂,这些催化剂能与过氧化氢形成类Fenton试剂,产生羟基自由基,以降解含能材料废水中的难生物降解有机物。组合工艺和Fenton强化方法的开发将为降低含能材料废水处理成本提供成本优势。

The integrated Fenton and Fenton-like processes to improve the degradation efficiency were reviewed. Ultrasound and microwave assisted advanced oxidation processes for decontamination of organic wastewater were described. The transition metal ions in the wastewater or oxides in the clay, zero valent iron, fly ash, ere, could be used as the alternative catalysts for Fe^2＋ and generate hydroxyl radical to degrade the energetic compounds. The competitive purification process in cost for energetic material wastewater could be developed by integrated processes and enhanced Fenton processes.
