摘要
为了解石化行业挥发性有机化合物(VOCs)的污染排放特征,选取惠州市石化污水处理厂及树脂生产加工车间释放的废气为调查对象,采用"冷阱富集—GC/MS"技术检测了这两类废气中VOCs的含量与组成。结果表明:石化污水处理厂主要污染物为烷烃、苯系物及烯烃等3类共64种VOCs成分,总浓度为241 mg/m^3,特征污染物为间/对二甲苯,质量分数为6.4%;树脂生产加工车间中主要污染物为烷烃、苯系物及醛类等3类共27种VOCs成分,总浓度达1235 mg/m^3,特征污染物为2-乙基-1,3-二氧戊环,质量分数为18.5%。
To discover the properties of the emission of volatile organic compounds（ VOCs）,one petrochemical wastewater treatment plant and one resin production workshop located in Huizhou,Guangdong provice were investigated. The species of VOCs and their concentrations were detected by gas chromatography-mass spectrometry（ GC/MS）. The results showed that about 64 VOCs with total concentration of 241 mg/m^3 were detected in waste gases emitted from the petrochemical wastewater treatment plant. These compounds could be classified into several categories including alkanes,aromatic compounds and olefin. Toluene and p-xylene were the top two abundant pollutants,both compound accounted for 6. 4% of total VOCs.Comparatively,only 27 VOCs with total concentration of 1 235 mg/m^3 were detected presenting in the waste gas from the resin production workshop,and mainly comprised of alkanes,aromatic compounds and aldehydes. 2-ethyl-1,3-dioxolane was found as the most abundant species,which accounted for 18. 5% of VOCs.
