摘要
甲基叔丁基醚(MTBE)是一种无铅汽油添加剂,其广泛使用造成了土壤和地下水污染;同时对人类有可疑致癌作用,因此成为人们关注的焦点。对近年来国外MTBE的污染治理技术研究进展进行了综述,并对主要方法进行了对比。在适宜的微生物存在条件下,MTBE的生物降解是可以发生的;植物修复技术可用于地下水和土壤污染治理;物理化学方法种类繁多,包括吸附和高级氧化等,其处理效率高成本也较高;新的处理技术如渗透性活性障壁PRB、膜分离/催化技术等也在研究之中。
Methyl tert-butyl ether has been used extensively in the world as a gasoline additive to enhance fuel octane ratings and reduce vehicle emissions. The widespread use of MTBE has led to its contamination of soil and groundwater. This paper focuses on the recent publications to show the newest progress of treatment of MTBE. Both aerobic and anaerobic strategies may be applicable, and phytoremediation is a useful option. Adsorption and advanced oxidation can remove MTBE in a short period.
