| 摘 要： | 研究了O3、O3/H2O2深度氧化法对饮用水中的Geosmin、MIB、IBMP、IPMP及TCA等痕量异味物质的去除效能。当O3投加量为4.66mg/L时,对痕量异味物质的去除率按IBMP、TCA、Geosmin、IPMP和MIB的排列,其中对Geosmin的绝对去除量最大,达到了140ng/L。投加O30.43mg/L和H2O210mg/L氧化去除5种痕量异味物质,对IBMP和TCA去除率分别达到75%和67.2%,去除效率较高;但在O3及O3/H2O2这样的投加量下,痕量异味物质尚不能达到标准中对嗅阈值的要求,还需配合后续处理工艺。

| Abstract: | This paper studied the O3 and O3/H2O2 advanced oxidation to treat the trace taste and odor matters,such as Geosmin,MIB,IBMP,IPMP,and TCA.When the O3 dosage was 4.66 mg/L,the sequence of removal effect was as: IBMP,TCA,Geosmin,IPMP,and MIB;among them the absolute removal of Geosmin was the maximum reaching 140 ng/L.When the 0.43 mg/L O3 and 10 mg/L H2O2 were dosage to oxidize these five trace taste and odor matters,the removal rate of IBMP and TCA were 75% and 67.2% respectively,which were relatively higher.... |
