摘　　要：采用实验室模拟方法和GC-MS等监测手段,研究了混合收集的城市生活垃圾好氧降解过程中释放的挥发性有机物(VOCs)组成特征和8种主要物质的释放浓度。结果表明:好氧生物处理过程中释放出的VOCs共检出94种。生物干化过程中,VOCs释放浓度总量集中前3天,占总浓度的77.8%,随着通风进行和有机物降解,VOCs排放量逐步降低。并对几种重要的VOCs,如有机硫化物和芳香烃等的释放规律进行了定性或定量分析。The composition characteristics of VOCs released from aerobic decomposition of municipal domestic waste and the releasing concentration of 8 main substances were researched by using the monitoring methods of laboratory simulation and GC-MS.The results showed that 94 kinds of VOCs were detected during the process of aerobic biological treatment. VOCs concentration was largely released in the first 3 days of the biological drying,reaching to 77. 8% of total release concentrations. The emission of VOCs reduced gradually accompanied with ventilation and organic degradation. And the emission characters of organic sulfide and aromatic hydrocarbons were qualitatively and quantitatively analyzed.
