摘要
为探究宁波石化经济开发区恶臭污染特征,分别在工业区和居民区,于下午、夜间及凌晨进行走航监测。结果表明:工业区检出硫化氢(H2S)、氨(NH3)、苯乙烯(SM)、甲硫醇(MT)、甲硫醚(DMS)和三甲胺(TMA)6种污染物,浓度均低于厂界排放标准;居民区检出的4种恶臭污染物(H2S,NH3,SM和TMA),仅H2S出现超标现象;工业区和居民区污染物种类差异不大,但工业区污染物浓度整体高于居民区,尤其是NH3和H2S;从嗅阈值角度分析,工业区和居民区主要受NH3和H2S影响,此外,居民区还受到SM,TMA影响。运用特征雷达图分区域和时段呈现恶臭污染情况,有助于认识恶臭污染水平和分布特征,可为恶臭污染控制提供参考。
In order to explore the characteristics of odor pollution in Ningbo Petrochemical Economic Development Zone,cruise observations was used to monitor odor gas at industrial areas and residential areas in afternoon,night and early morning.The results showed that:hydrogen sulfide(H2S),ammonia(NH3),styrene monomer(SM),methyl mercaptan(MT),methyl sulfide(DMS)and trimethylamine(TMA)detected in industrial zone were lower than Boundary Emission Standards;while H2S,NH3,SM and TMA were detected in residential area,only H2S exceeded the standard was caught.there was little difference in odor components between industrial areas and residential areas.The concentration of odor factors detected in industrial areas was higher than that in residential areas,especially NH3 and H2S.Industrial areas and residential areas were mainly affected by NH3 and H2S from the perspective of olfactory threshold.In addition,the residential area was also affected by SM and TMA.The characteristic radar chart showed the odor pollution characteristics in different regions and time periods,which is helpful to understand the odor pollution level and distribution characteristics and provide reference for odor pollution control.
