【摘要】 应用GC/MS联机检测技术对 11个城市污泥中 6种含氮有机污染物进行分析。结果表明 ,城市污泥中 6种含氮有机化合物的总含量在 0 0 87～ 2 6 4 38mg·kg-1,高低依次为兰州污泥 >北京污泥 >无锡污泥 >大埔 (香港 )污泥 >沙田 (香港 )污泥 >佛山污泥 >广州污泥 >元朗 (香港 )污泥 >珠海污泥 >西安污泥 >深圳污泥。不同化合物在各城市污泥中的含量和分布特征有明显差异。硝基苯类的含量较高 ,胺类的含量较低。兰州污泥中含氮有机化合物的含量普遍较高 ,其次是无锡污泥、北京污泥和大埔污泥。污泥中含氮有机化合物的种类和含量与污水来源、污水处理方式、污泥类型、化合物的结构和理化性质等因素有关更多还原

【Abstract】 Organic pollutants such as nitro-organic compounds in sewages sludges are important factor limiting application of sludge to agricultural land.Six nitro-organic compounds classified as US EPA priority pollutants in eleven municipal sludges from elected cities of China were determined by GC/MS.Total contents of nitro-organic compounds in all sludges ranged from 0 087 mg·kg -1 to 26 438 mg·kg -1,decreasing in the order of Lanzhou>Beijing>Wuxi>Dapu>Shatian>Foshan>Guangzhou>Yuanlang>Zhuhai>Xi’an>Shenzhen.Concentrations and distribution patterns of compounds in different sludges were significantly various,with higher nitrobenzenes and lower anilines respectively.Higher concentrations for most compounds were detected in Lanzhou sludge,following by Wuxi sludge,Beijing sludge and Dapu sludge.Compounds detected in different municipal sludges and their concentration were related to the sources of wastewater,wastewater-treating methods,sludge type,physical-chemical properties of compound themselves,etc.更多还原
