摘　　要：为系统评估生活垃圾渗滤液处理设施及周边不同点位的恶臭污染情况,以南方某渗滤液处理厂为例,对29种主要恶臭物质进行监测,对比采用嗅阈值、阈稀释倍数以及综合污染指数对恶臭污染进行定量化综合评估。结果表明:甲硫醚、二硫化碳、三甲胺、二甲二硫、硫化氢和甲硫醇是渗滤液处理设施的六种主要恶臭物质,占总恶臭物质比例的97.96%~99.86%,具有较强的代表性,可作为此类设施环境臭味物质监测的重点监测指标。渗滤液处理设施综合恶臭污染指数的变化范围在7.4~15.15之间,与采用臭袋法测定的臭气浓度的变化一致。因此,渗滤液处理厂的恶臭污染评估可以采用六种主要恶臭物质为依据,利用综合恶臭指数反映人体对臭气的嗅觉感受,提高监测效率,为此类设施的恶臭污染监测与评估提供重要参考。In order to systematically evaluate the odor pollution situation of a domestic garbage leachate treatment plant and its surrounding sites,this paper took a leachate treatment plant in South China as an example.Through the monitor and analysis of 29 malodorous substances,the odor pollution was quantitatively and comprehensively evaluated by olfactory threshold,threshold dilution ratio and comprehensive pollution index.The results showed that six main odorous substances were screened out by calculating the dilution ratio of odorous substances at different points,which were methyl sulfide,carbon disulfide,trimethylamine,dimethyl disulfide,hydrogen sulfide and methanethiol,accounting for 97.96%~99.86%of the total odorous substances,which had a strong representation and can be used as key monitoring indexes for odor substances in the surrounding environment of leachate treatment plant.At the same time,the comprehensive odor pollution index of leachate treatment facilities varied from7.4 to 15.15,which was consistent with the variation of odor concentration measured by the odor-bag method.Therefore,the odor pollutionassessment of leachate treatment plant can be based on six main odor substances,and the comprehensive odor index can be used to reflect the olfactory perception of odor,improve the monitoring efficiency,and provide an important reference for odor pollution monitoring and assessment of such facilities.
