摘　　要：本研究旨在探索协同催化氧化法在深度处理焦化废水中的应用。通过采用臭氧、过氧化氢(H_(2)O_(2))、紫外光(UV)和活性炭(AC)等催化剂的组合,研究了不同条件下对焦化废水中化学需氧量(COD)的去除效果。结果表明,O_(3)/H_(2)O_(2)组合能产生大量羟基自由基加速有机物氧化;O_(3)与UV的组合在254nm波长下最有效,而O_(3)与AC的组合则利用活性炭的大比表面积提高处理效率。特别是,紫外/活性炭协同催化臭氧氧化试验表明,当紫外光强度为0.63 m W/cm^(2)时,COD去除率可达最佳。本文研究结果为焦化废水的高效深度处理提供了有效的技术参考。This study aims to explore the application of synergistic catalytic oxidation method in the deep treatment of coking wastewater.The removal efficiency of chemical oxygen demand(COD)in coking wastewater under different conditions was studied by using a combination of catalysts such as ozone,hydrogen peroxide(H_(2)O_(2)),ultraviolet light(UV),and activated carbon(AC).The results indicate that the combination of O_(3)/H_(2)O_(2) can generate a large amount of hydroxyl radicals to accelerate the oxidation of organic compounds.The combination of O_(3) and UV is most effective at a wavelength of 254 nm,while the combination of O_(3) and AC utilizes the large specific surface area of activated carbon to improve treatment efficiency.Especially,the UV/activated carbon synergistic catalytic ozonation experiment showed that the COD removal rate can reach its optimal level when the UV intensity is 0.63 mW/cm^(2).The research results of this article provide effective technical references for the efficient deep treatment of coking wastewater.
