摘　　要：为了解天津城市污水泵站恶臭的污染程度,选取天津市一个典型的城市污水泵站进行为期3天的采样,采集该污水泵站距离污染源强不同距离处的恶臭气体样品,用气相色谱-质谱联用仪（GS-MS）和分光光度法对采集样品的组分含量进行检测,比较了恶臭排放源点和不同距离处的恶臭组分的浓度特征和污染现状.结果表明,该泵站恶臭污染物质以硫化氢、二氯甲烷和苯系物为主,还有一些烯烃和芳香烃衍生物;恶臭物质的浓度变化范围是n.d.～ 0.073 7mg/m3,大部分恶臭物质浓度一般由高至低表现为源点＞下风向5 m,源点＞背景值,环境空气采样点与恶臭排放源相比,其降幅明显;虽然检测到的恶臭组分较多,但是其浓度与《恶臭污染物排放标准》（GB 14554-1993）等标准中规定的排放限值相比,均未超标.In order to research the odorous pollution levels of Tianjin urban sewage pumping station,an urban sewage pumping station was chosen for three days sampling.The samples were collected which had different diffusion distance from the odorous emission source.The concentrations of the samples were analyzed by gas chromatograph-mass spectrometer （GC-MS） and speetrophotometer.To discuss the odorous pollution levels of the urban sewage pumping station,the concentrations of the odorous emission source and the environment sampling points were compared.The results showed that the main pollutants were hydrogen sulfide,dichloromethane,benzene contents and aromatic hydrocarbons et al.The concentrations ranged from n.d.to 0.073 7mg/m3.The concentrations of the most odorants were in the order：the odorous emission source 〉 the 5 meters of downwind director,the odorous emission source 〉 background point.The concentrations of the environment sampling points decreased obviously,compared with the odorous emission source.And all the concentrations of the odorants did not exceed the emission limits of ＂emission standards for odor pollutants＂（GB14554-93） and other standard.
