摘要
当前各水源地水华暴发现象频发,导致水源水质污染严重。土臭素(GSM)和2-甲基异莰醇(2-MIB)是较为常见的藻类代谢嗅味产物,也是导致水体产生土臭味的主要原因。常规除藻技术虽然能够去除水体中的藻类,但对其生成的嗅味产物去除效果不佳,因此,亟需新技术在除藻的情况下实现同步去除嗅味产物。文中结合藻类与嗅味产物的相关性,综述常规除藻技术的局限性,介绍高级氧化工艺(AOPs)对于两者去除的研究应用,并认为AOPs将成为同步除藻除嗅技术的研究热点,为同时除藻除嗅技术进一步研究与应用提供理论依据。
Water bloom occurrs frequently in the headwaters,which threatens water quality safety.Geosmin(GSM)and 2-methylisoborneol(2-MIB)are common odorous substances metabolized by algae,which are perceived as resulting the main causes of odor in water.Although,the conventional removal technology can remove algae,the removal effect on the odorous substances is not satisfactory.Based on the correlation between algae and odor products,this paper summarizes the limitations of conventional algal removal technology,introduces the research and application of advanced oxidation processes(AOPs)for the removal of both,and believes that AOPs can become a research hotspot of synchronous algal removal and odor removal technology,providing a theoretical basis for further research and application of simultaneous algal removal and odor removal technology.
