中文摘要: |
采用GC-MS法测定拉链排咪、塑料制品、包装印刷行业的生产车间无组织VOCs排放,得到3个工业源VOCs源成分谱。结果表明:不同工业源排放的VOCs组分存在明显差异,拉链排咪以苯系物为主,占比3529%,主要污染物为正己烷、二氯甲烷、甲苯;塑料制品中苯系物占比为4735%,甲苯、乙酸乙酯、正己烷为主要污染物;包装印刷中苯系物质量分数高达6367%,甲苯、1,2,4-三甲苯、丙酮为主要污染物 |
英文摘要: |
VOCs fugitive emission from the workshops of zipper, plastics, packaging and printing industries were detected by GC/MS, and VOCs source profiles from 3 industrial sources were obtained. The results showed that the components of VOCs from different industrial sources were significantly different. Benzene series were dominated in zipper industry, which accounted for 35.29% of TVOC. The main pollutants were n hexane, dichloromethane and toluene. Benzene series accounted for 47.35% in plastics industry, toluene, ethyl acetate and n hexane were the main pollutants. The mass fraction of benzene series in packaging and printing industry was up to 63.67%, toluene, 1,2,4 trimethylbenzene and acetone were the main pollutants. |
