摘　　要：为了研究秋季桂花盛开期间的花香是否会对企业厂界无组织臭气浓度和非甲烷总烃的浓度产生干扰和影响,探讨在此期间如何开展无组织废气监测的合理方案,针对厂界种植了较多桂花树的企业,分别在桂花盛开前和盛开期间的两个时段对企业的厂界无组织臭气浓度和非甲烷总烃进行监测。监测数据表明,在桂花盛开期间,厂界无组织臭气浓度和非甲烷总烃的浓度都明显高于桂花盛开前的监测浓度,臭气浓度甚至还出现超标的情况。由此可见,桂花的香味确实会对厂界的臭气浓度和非甲烷总烃的浓度产生正干扰,从而影响整个监测数据的准确性。因此,在桂花盛开的季节,检测机构应该根据现场实际情况,制定合理的无组织废气监测方案,避免桂花的花香对监测数据产生影响,从而确保监测数据的真实性和准确性。In order to investigate whether the fragrance of osmanthus during its blooming period in autumn will interfere and affect the concentration of unorganized odor and non methane total hydrocarbons at the factory boundary of enterprises,and to explore a reasonable plan for conducting unorganized exhaust gas monitoring during this period,for enterprises that have planted a large number of osmanthus trees at the factory boundary,the concentration of unorganized odor and non methane total hydrocarbons at the factory boundary of enterprises were monitored before and during the blooming period of osmanthus.Monitoring data shows that during the blooming period of osmanthus,the concentration of unorganized odor and non methane total hydrocarbons at the factory boundary are significantly higher than the monitoring concentration before osmanthus blooms,and the odor concentration even exceeds the standard.From this,it can be seen that the fragrance of osmanthus does indeed have a positive interference on the odor concentration and non methane total hydrocarbon concentration at the factory boundary,thereby affecting the accuracy of the entire monitoring data.Therefore,during the blooming season of osmanthus,testing agencies should develop a reasonable unorganized exhaust gas monitoring plan based on the actual situation on site to avoid the impact of osmanthus fragrance on monitoring data,thereby ensuring the authenticity and accuracy of monitoring data.
