| 摘 要： | 采用顶空-固相微萃取和色谱质谱联用仪器方法调查严重污染的河流、相关水源中甲硫醚嗅味物质的分布.结果表明,河流中甲硫醚浓度高达2 907 ng/L,受污染的相关水源中甲硫醚浓度达到53 ng/L.单独陶瓷无机膜工艺对DMS去除的效果为20％左右,而臭氧氧化则具有较好的效果,臭氧-陶瓷膜组合工艺对DMS去除率达到50％～9...

| Abstract: | Investigation of heavily polluted rivers was conducted with emphasis on dimethyl sulfide(DMS) contamination using headspace solid-phase micro-extraction(HS-SPME) together with GC-MS.The source water in association with the polluted rivers was also contaminated with source water concentration up to the range from 50 to 90 ng/L.Removing DMS,the notorious odor compound,was important in tap water production especially when the source water was contaminated.Thus ceramic membrane filtration modules were used to p... |
