2025年11月常州大学低碳清洁能源与安全高效燃烧科研团队孙运兰教授课题组刘俊博士/讲师在Process Safety and Environmental Protection期刊发表了题为“Emission characteristics and odor activity of VOCs from a medical waste incineration plant: Evaluating the performance of air pollution control devices”的研究论文。
随着医疗服务的快速扩张，医疗废物的产生量持续增长，这使得焚烧过程中挥发性有机物（VOCs）的释放问题引发广泛关注。本研究在中国北方某典型医疗废物焚烧厂开展全流程烟气采样，以探究VOCs的排放特征及空气污染物控制装置（APCDs）的协同脱除性能。共检测到50种VOCs物质，其浓度经APCD处理后从5334.3±1720.8微克/立方米显著降至471.24±68.67微克/立方米。与此同时，优势VOCs组份由含氧VOCs（74.83%→20.09%）转变为芳香烃（13.68%→46.26%），其中丙酮、苯乙烯和四氯化碳为含量最丰富的化合物。在各处理单元中，旋风分离器、活性炭喷射与布袋除尘器组合系统（CS+ACI+FF）表现出最优协同效率，可实现90.1%的VOCs脱除，而湿式洗涤装置（WS）的脱除效果有限，尤其对芳香烃类物质。研究确认吸附、冷凝和溶解是APCDs去除VOCs的主要机制。恶臭评估表明APCDs能有效缓解异味污染，使烟气总臭气活性值降低64.76%，但某些低嗅阈值的化合物（如苯和氯仿）仍会加剧异味污染，提示存在潜在环境与健康风险。测算得出该焚烧厂的VOCs排放因子为16.29±2.37毫克/千克废物，现有APCDs系统每年可减少约2683.88千克VOCs排放。

三、英文摘要
With the rapid expansion of healthcare services, the generation of medical waste has been continuously increasing, raising significant concerns about the release of volatile organic compounds (VOCs) during incineration. In this study, full-process flue gas sampling was conducted at a representative medical waste incineration (MWI) plant in northern China to investigate the emission characteristics of VOCs and the synergistic removal performance of air pollution control devices (APCDs). A total of 50 VOC species were detected, with their concentrations decreasing significantly from 5334.3±1720.8 μg/m3to 471.24±68.67 μg/m3after APCD treatment. Meanwhile, the dominant VOCs groups shifted from oxygenated VOCs (74.83% → 20.09%) to aromatics (13.68% → 46.26%). Acetone, styrene, and carbon tetrachloride were the most abundant compounds. Among different units, the combined cyclone separator, activated carbon injection, and fabric filter (CS+ACI+FF) system exhibited the highest synergistic efficiency, achieving a 90.1% reduction of VOCs, while the wet scrubbing (WS) device showed limited effectiveness, particularly for aromatics. Adsorption, condensation, and dissolution were identified as the main mechanisms of VOCsremoval in APCDs. Odor assessment revealed that APCDs effectively mitigated odor pollution, reducing the total odor activity value of flue gas by 64.76%. Nevertheless, some compounds with low odor thresholds (e.g., benzene and chloroform) still contributed disproportionately to odor pollution, indicating potential environmental and health risks. The VOC emission factor of the MWI plant was estimated at 16.29±2.37 mg/kg-waste, and existing APCDs were calculated to reduce annual VOC emissions by approximately 2683.88 kg.
