  • 摘要: 为了考察焦化废水臭氧催化氧化深度处理过程中污染物的降解特征，对处理过程中的废水进行了COD、TOC、BOD、紫外可见光谱、高效液相色谱、气相色谱-质谱联用（GC-MS）和凝胶色谱等多种分析。结果表明：经臭氧催化氧化处理后，废水的COD、TOC和UV254均降低，降低速度大小为UV254 >COD >TOC；臭氧催化氧化可提高废水的可生化性，但氧化时间进一步延长，可生化性反而降低；液相色谱表明非极性物质优先得到去除；凝胶色谱表明分子量较小的物质优先去除；GC-MS结果表明焦化废水混凝出水中主要成分为苯酚类、杂环化合物、多环芳烃及其衍生物，臭氧催化氧化处理后这些化合物都得到有效降解。
    Abstract: Chemical oxygen demand (COD), total organic carbon (TOC), biological oxygen demand (BOD), ultraviolet-visible spectroscopy (UV-VIS), high performance liquid chromatography (HPLC), gas chromatograph-mass spectrometer (GC-MS), and gel permeation chromatography (GPC) analyses were performed on wastewater sampled during the catalytic ozonation of coking wastewater in order to study the characteristics of pollutant degradation during this process. The results showed that COD, TOC, and UV254 of the wastewater were lower following the catalytic ozonation treatment, and the rates of decrease were as follows: UV254 > COD> TOC. The biodegradability of wastewater was improved by the catalytic ozonation treatment; however, when the ozonation time was prolonged, the biodegradability decreased. HPLC results showed that nonpolar substances were removed in preference. GPC results showed that smaller-molecular-weight substances were removed in preference. GC-MS results showed that phenols, heterocyclic compounds, polycyclic aromatic hydrocarbons, and their derivatives were the main pollutants in the coagulation effluent of coking wastewater, and these substances were effectively oxidized after catalytic ozonation.
