  • 摘要: 焦化废水是典型的具有复杂有机质的工业废水,其复杂的有机构成制约了水处理的水质达标,且可能对排入水体构成危害.为了探明其溶解性有机物的组成,采用XAD-8大孔树脂将焦化废水中的溶解性有机物分为亲水性组分(HIS)、疏水酸性组分(HOA)、疏水碱性组分(HOB)和疏水中性组分(HON),分析了各组分的溶解性有机物(DOC)、紫外-可见光谱、色度,并采用GC/MS对各组分中有机物进行定性分析.结果表明,焦化废水中的有机物主要为HIS和HOA组分,其DOC含量分别占总DOC的44.3%和32.4%;焦化废水在200—250 nm和300—400 nm范围内有特征吸收峰,且吸收光强度顺序为HIS>HOA>HON>HOB;焦化废水的色度主要由HOA和HON构成,其在525 nm和436 nm处的吸光度分别占焦化废水吸光度的42.9%(HON)、42.1%(HON)和21.4%(HOA)、15.8%(HOA);焦化废水中亲水性物质主要是苯胺、苯酚、喹啉、异喹啉,疏水酸性物质中主要是各种甲基取代的酚类物质,疏水碱性物质主要是各种胺类和含氮杂环化合物,疏水中性物质主要是吲哚及其衍生物.
    Abstract: Coking wastewater is the representative wastewater containing various organic pollutants. In order to ascertain the composition, XAD-8 resin was applied to concentrate and isolate the organic compounds in coking wastewater. Dissolved organic matter in coking wastewater was fractionated into four different fractions: hydrophobic acids (HOA), hydrophobic bases (HOB), hydrophobic neutrals (HON) and hydrophilic substances (HIS). Thereafter, the dissolved organic carbon (DOC), ultraviolet-visible (UV) absorption spectroscopy, chroma and the organic component were determined. The DOC values of HIS and HOA showed these two were the main fractions of DOM, comprising 44.3% and 32.4% of the total sample. The characteristic absorption wavelength of coking wastewaater ranged from 200 nm to 250 nm and 300 nm to 400 nm, and the intension order was HIS>HOA>HON>HOB. The chroma of coking wastewater was composed of HOA and HON, and their absorbance at 525 nm and 436 nm contributed 42.9%, 42.1% and 21.4%, 15.8% of the total. The dominant compounds were aniline, phenol, quinoline and isoquinoline for HIS, various alkyl phenols for HOA, aniline bases and polycyclic nitrogen-containing aromatics for HOB and indole with its ramifications for HON.
