利用吹扫捕集-GC/MS法对引起南宁市竹排冲河道水体黑臭的嗅味物质进行检测分析。结果表明,导致竹排冲水体黑臭的嗅味物质主要为苯系物、硫类化合物和氯苯类化合物,其中甲硫醚(相对含量1.70%)、二甲基二硫醚(相对含量3.19%)、甲基丙基二硫醚(相对含量6.11%)等挥发性有机物为竹排冲水体中的主要致嗅物质,是竹排冲水体嗅味产生的主要原因。
The purge-trap-GC / MS method was used to detect and analyze the olfactory components of black-smelly water that caused the water body in the Tachai River in Nanning. The results showed that the odorous substances that caused the black-smelly bamboo flushing body were mainly benzene series, sulfur compounds and chlorobenzenes, among which dimethyl sulfide (relative content 1.70%), dimethyl disulfide (relative content 3.19% ), Methylpropyl disulfide (relative content 6.11%) and other volatile organic compounds are the main olfactory substances in bamboo flushing body, which is the main reason for the smell of bamboo flushing body.
