| 摘 要： | 为确定某ABS树脂装置丁二烯聚合工段废水水质,特别是特征有机物种类,采用吹扫捕集、静态顶空、固相萃取、固相微萃取和液液萃取等预处理方法与GC/MS(气相色谱/质谱)联用,定性检测出该工段废水中含有16种挥发、半挥发性有机物,主要包括烯烃、苯系物、有机腈、多环芳烃、醚、醇和胺. 废水ρ(SS)(SS为悬浮物)为540.31 mg/L；SS粒径主要分布在0.10~5.00 μm之间,可吸附水中4.83%~33.21%的对二甲苯、乙苯、苯乙烯和1,5-环辛二烯等有机物. 与生活污水不同,该工段废水三维荧光光谱图的荧光区域集中在λEx/λEm(激发波长/发射波长)=205~285 nm/310~360 nm范围内,主要包括λEx/λEm为285 nm/350 nm、260 nm/310 nm、225 nm/345 nm、210 nm/315 nm、230 nm/360 nm的5个荧光峰,由甲苯、靛蓝、苯乙烯、脱氢松香酸、芴、菲等苯系物和多环芳烃类有机物引起. 废水在200~250 nm之间有较强紫外吸收峰,主要由1,3-丁二烯、苯甲醛、苯乙酮、4-苯基-1-环己烯等共轭二烯、不饱和醛、酮和苯系物等有机物引起.

| Abstract: | In order to determine the quality of wastewater from a section of butadiene polymerization, purge and trap, static headspace, solid-phase extraction, solid-phase microextraction and liquid-liquid extraction as pretreatment methods coupled with GC/MS (gas chromatography/mass spectrometry) were used for analysis of the wastewater. In total 16 kinds of volatile and semi-volatile organic compounds were found in the wastewater including alkene, benzenes, organic nitrile, polycyclic aromatics, ethers, alcohols and amines. The concentration of suspend solids (SS) was 540.31 mg/L, while the particle sizes ranged from 0.10-5.00 μm. Its adsorption capacities for xylene, ethylbenzene, styrene, 1,5-cyclooctadiene and other organic matter were 4.83%-33.21%. Significant differences were found between the wastewaters from the butadiene polymerization section and domestic sewage. Fluorescent regions of the former focused on λEx /λEm =205-285 nm/310-360 nm, which mainly consisted of five fluorescence peaks λEx /λEm =285 nm/350 nm, 260 nm/310 nm, 225 nm/345 nm, 210 nm/315 nm and 230 nm/360 nm. The five peaks were caused by benzenes and polycyclic aromatics such as toluene, indigo, styrene, dehydroabietic acid, fluorene and phenanthrene. UV absorption spectrophotometry focused around 200-250 nm, which was caused by conjugated diolefins, unsaturated aldehydes, ketones, and benzenes such as 1,3-butadiene, benzaldehyde, acetophenone and 4-phenyl-1-cyclohexene. |
