中文摘要:

饮用水源中微囊藻毒素(MC)的问题已经引起人们的广泛关注,而一些常规的MC处理方法都各有其局限性。高级氧化技术是一类高效降解MC,的方法,且降解产物没有生物毒性。本文全面阐述了TiO2紫外光催化氧化、TiO2,uv/H2O2、TiO2/UV/高铁酸盐联用工艺、可见光催化氧化、Fenton法、光助Fenton法,O3/H2O2及O3/Fe抖这些高级氧化技术降解MC的研究进展。并根据现有高级氧化技术降解MC研究中的一些不足之处,提出了MC高级氧化处理领域今后研究的主要方向和需解决的问题。

英文摘要:

More attention had been paid on the pollution of microcystins (MC) in the drinking water sources in recent years. However, the conventional methods of MC degradation all have their own limitations. Advanced oxidation processes (AOPs) are a highly effective means for MC degradation. The related research of advanced oxidation processes for the degradation of microcystins are summarized, including titanium dioxide (TiO2) photocatalytic oxidation, photoeatalysis combined with hydrogen peroxide or ferrate, visible light photocatalytic degradation, Fenton and photo-Fenton oxidation, O3/H2O2 and O3/Fe^2+. In view of the disadvantages of these AOPs researches for MC degradtion, the issues and the problems that need to be resolved for the MC degradation during AOPs in the future are proposed.
