水中MTBE污染治理技术研究进展

摘要

Methyl tea-butyl ether (MTBE),as a gasoline blending component with high octane rating,has widely been used.However,MTBE,itself,is a kind of potential pollutant in the environment.The MTBE which leaked to the environment in the courses of storage,transportation and utilization may cause pollution to water bodies.The pollution treatment technologies of MTBE in water both in China and abroad,such as adsorption,advanced oxidation,microbiological degradation,phytoremediation,etc.are summarized.The main adsorbents for adsorption are activated carbon,zeolite,resins,etc.The advanced oxidation method mainly includes catalytic oxidation,H2O2 oxidation,O3 oxidation,Fenton oxidation,electrochemical oxidation,etc.The microbiological degradation includes aerobic degradation and anaerobic degradation.%甲基叔丁基醚(MTBE)作为高辛烷值的汽油调和组分被广泛使用.但MTBE本身是一种潜在的环境污染物,在储存、运输和使用过程中泄漏到环境中的MTBE会对水体造成污染.综述了国内外有关水中MTBE的污染治理技术,主要有吸附、高级氧化、微生物降解、植物转移修复等技术.吸附用吸附剂主要有活性炭、沸石、树脂等;高级氧化法主要包括催化氧化、H2O2氧化、O3氧化、Fenton氧化、电化学氧化等;微生物降解有好氧降解和厌氧降解.
