石油添加剂甲基叔丁基醚的污染治理技术研究进展

Study Progress on Treatments of the Gasoline Additive Methyl Tert-Butyl Ether Contamination

甲基叔丁基醚是一种石油添加剂,广泛应用于中高档汽油中。其对环境造成的污染和对人体健康造成的危害已日益引起人们的高度重视。本文综述了近年来国外有关甲基叔丁基醚的污染治理技术研究进展,主要是高级氧化技术和微生物降解。已用于处理甲基叔丁基醚的高级氧化技术包括;多相光催化氧化法、紫外光加强的过氧化氢氧化法、臭氧法与臭氧-过氧化氢联合氧化法、超声法与超声-臭氧联合氧化法、芬顿法与光芬顿氧化法、氧气的还原性活化和水的γ射线辐射。微生物降解主要涉及有氧代谢和无氧代谢两大途径。

Methyl ten-butyl ether is a widely used gasoline additive.Its presence in the environment causes a widespread pollution and poses a serious threat to human health.Current literature on the treatments of methyl tert-butyl ether contamination,including advanced oxidation processes and microbial biodegradation,is reviewed.The advanced oxidation technologies include heterogeneous photocatalytic oxidation,UV/H2O2 oxidation,conventional ozonation and ozone/hydrogen peroxide,ultrasound irradiation and sonolytic degradation in the presence of ozone,Fenton's reagent and UV-assisted Fenton's reagent,reductive activation of dioxygen as well as r radiolysis of H2O.Microbial biodegradation of MTBE involves both the aerobic and anaerobic metabolism.
