摘要
使用MCX/MAX萃取柱对炼油污水处理厂二沉池出水中的溶解性有机物(DOM)进行分离,获得疏水酸性组分(HOA)、疏水碱性组分(HOB)、疏水中性组分(HON)和亲水物质(HIS)4种亚组分。使用三维荧光光谱和电喷雾-傅里叶变换离子回旋共振质谱对各组分进行了组成表征,结果表明:二沉出水中存在酚类物质和石油类物质的特征荧光峰;HOA组分中化合物类型较多,主要为CHOS类物质;HOB组分中检测到的物质较少,主要为O_(3)S_(1)物质;HON组分中有较多的CHOS、CHON和CHO类物质。以上研究结果可为炼油污水处理工艺优化和外排水环境影响评估提供参考。
The dissolved organic matter(DOM)in the effluent from the secondary effluent of a refinery wastewater treatment plant was separated by MCX/MAX extraction column,and four sub-components including hydrophobic acidic component(HOA),hydrophobic alkaline component(HOB),hydrophobic neutral component(HON)and hydrophilic substance(HIS)were obtained.3D-EEM and ESI FT-ICR MS were used to analyze each component.The results showed that specific fluorescence peaks of phenolic substances and petroleum substances existed in the refined wastewater,there were more compounds in HOA component,which mainly was CHOS substances;less substances were detected in HOB component,which mainly was O_(3)S_(1) substances,and more CHOS,CHON and CHO substances were observed in HON component.This study makes an in-depth analysis of DOM in the effluent of refined wastewater,providing a reference for treatment process optimization and environmental impact assessment of external drainage of refinery wastewater.
