摘　　要：废纸制浆造纸已逐渐成为造纸行业的主导,但其废水量大、污染严重。以山鹰国际控股有限公司某造纸厂废纸制浆造纸废水为例,探讨了废水中溶解性有机污染物(DOM)的特性及其迁移转化规律。采用紫外可见光谱、红外光谱、三维荧光光谱、凝胶渗透色谱(GPC)及气相色谱-质谱(GC-MS)等仪器对水样中的DOM进行特性表征。结果表明,废纸制浆造纸废水中DOM主要以疏水性的芳香族化合物、长链烷烃类物质为主,分子质量分布广泛,经过生化处理后,二级出水中仍含有难降解的腐殖酸类物质;高级氧化处理后,废水的COD大大降低,最终出水中DOM主要是以含有苯环的腐殖质有机物为主。Waste paper making has gradually become the leader of the papermaking industry,but the wastewater of the industry has the characteristics of large amount of production and serious pollution.Taking the wastewater from the waste paper making in a paper mill of Shanying International Holdings Co.,Ltd.,the characteristics,migration and transformation of dissolved organic pollutants(DOM)in the wastewater were discussed.The characteristics of DOM in wastewater were characterized by UV-Vis spectrum,infrared spectrum,three-dimensional fluorescence spectrum,gel permeation chromatography(GPC)and gas chromatography-mass spectrometry(GC-MS).The results showed that the DOM in wastewater was mainly hydrophobic aromatic compounds and long-chain alkanes,and the molecular weight was widely distributed.After biochemical treatment,the secondary effluent still containedrefractory humic acids.After advanced oxidation treatment,the COD of the wastewater was greatly reduced,and the final effluent DOM was mainly humic organic matter containing benzene ring.
