摘要

摘要: 上海某垃圾填埋场填埋量大,垃圾成分环境风险高,亟需对其释放的挥发性有机物(VOCs)变化特征及相关控制方法进行深入研究。采用GC-MS测定不同季节填埋场释放的VOCs各组分浓度,对比喷洒除臭剂对VOCs的影响,并评估其环境及健康风险,以判断不同季节VOCs的首要控制污染物、臭氧生成关键污染物以及表征职业暴露风险,以期为后续有针对性地控制和去除VOCs提供技术支撑。结果表明:VOCs总浓度夏季最高,以烷烃类和醛酮类为主,其中异戊烷、丙酮是优势化合物;除臭剂对臭气、NH₃、H₂S有一定去除效果,但增加了填埋场VOCs的种类和浓度、臭氧生成潜势、非致癌风险与致癌风险,但都在可接受范围内。

Abstract: The landfill in Shanghai has a large volume and the environmental risk of the garbage components is high, and it is essential to deeply study the variation characteristics and related control methods of the release of volatile organic compounds (VOCs). GC-MS was used to determine the concentrations of VOCs released from landfills in different seasons, compare the effects of deodorant spraying on VOCs, and assess their environmental and health risks. The primary control pollutants of VOCs, the key pollutants of ozone generation, and the characterization of occupational exposure risks at different seasons were thus determined, so as to provide technical support for subsequent targeted control and removal of volatile organic compounds. It was found that the total concentration of VOCs was the highest in summer, mainly with alkanes, aldehydes and ketones, of which isopentane and acetone were the dominant compounds. The deodorant had a certain removal effect on the odor concentration, NH₃ and H₂S, but increased the varieties and concentration of VOCs, enhanced the ozone generation potential, and could raise the non-carcinogenic risk and carcinogenic risk in the landfill, both of which were within acceptable risk levels.
