摘　　要：利用气相色谱／质谱联用仪分析了郑州八岗污泥处置厂污泥好氧堆肥发酵高温前期（第5天）的挥发性有机物（VOCs）产生与释放特征。结果表明，污泥堆肥过程中产生的主要致臭VOCs为甲硫醇、甲硫醚、二甲二硫醚、丙酮、1-丁烯；致臭VOCs从堆体内部到车间人员活动处的扩散过程中，其浓度可降低89．3％-99．9％，低于《工作场所有害因素职业接触限值》（GBZ2—2002）和《恶臭污染物排放标准》（GB14554-93）所规定的限值，厂区不存在VOCs污染风险。The production and emission of volatile organic compounds （VOCs） from sewage sludge aerobic composting during high-temperature period （the fifth day） in Bagang Sludge Treatment Plant in Zhengzhou City were analyzed by gas-chromatography-mass spectrometry. The results showed that the main odorous VOCs produced from sewage sludge aerobic composting were methanthiol, dimethyl sulfide, dimethyl disulfide, acetone and 1-butylene. The concentrations of VOCs could be decreased by 89.3% to 99.9% during atmospheric diffusion from the composting pile to staff activities, which were lower than the emission limits in Occupational Exposure Limit for Hazardous Agents in the Workplace （GBZ 2 -2002） and Emission Standards for Odor Pollutants （ G8 14554 - 93 ）.
