| 摘 要： | 建立液氮浓缩采样/热解析脱附/GC/MS联用分析方法,测量了广州猎德污水处理厂6个不同处理单元及2个周边环境点中挥发性卤代有机物的组分及含量水平,研究了其排放特征及影响因素.结果表明,8个采样点共检测出19种挥发性卤代有机物,包括11种卤代烷烃、3种卤代烯烃及3种卤代芳香烃、2种卤代酸酯等,平均检出浓度范围为n.d.～33.39μg·m-3,总浓度均值范围为34.91～127.74μg·m-3·CH2Cl2、CHCl3、CFC-12、C2H4Cl2、CFC-11、C2HCl3、C2Cl4是污水处理厂主要的挥发性卤代有机物,它们主要由污水中相应物质挥发而来.脱水机房挥发性卤代有机物浓度最高,提升泵房次之,污泥浓缩池最低;研究还发现,提升泵房、曝气池及生化池的挥发性卤代有机物排放过程中受温度、湿度因素影响明显. |

| Abstract: | A low enrichment method of using Tenax as absorbent and liquid nitrogen as refrigerant has been established to sample the volatile halogenated organic compounds in Guangzhou Liede municipal wastewater treatment plant as well as its ambient air.The composition and concentration of target halogenated hydrocarbons were analyzed by combined thermal desorption/GC-MS to explore its sources profile and impact factors.The result showed that 19 halogenated organic compounds were detected,including 11 halogenated alk... |
| Keywords: | volatile organic compounds(VOCs) halogenated compound source profile municipal wastewater treatment plant impact factors |
