摘要
多孔介质中的致病细菌及病毒等病原微生物迁移研究对保护饮用水资源具有重要意义.在归纳总结国内外已有研究资料的基础上,对微生物在多孔介质中迁移行为进行了分析.研究表明病原微生物作为生物胶体的一种,在迁移过程中受多种迁移机制共同作用.除常见水动力条件和水化学条件外,微生物在迁移过程中还受自身性质,介质颗粒及环境因素的影响.在此基础上,分别讨论了微生物在饱和多孔介质与非饱和多孔介质中的迁移行为,并对近年来研究热点及进展进行了简要概括.目前微生物在地下水中迁移研究日益丰富,但由于地下环境复杂性,微生物的易变异性,对于地下水系统中微生物造成的污染去除修复还需进一步探讨.
Understanding the fate and transport of pathogenic microorganisms in porous media is of great significance to protect water resources.On the basis of the previous research at home and abroad,the migration behaviour of microorganisms in porous media has been summarized.Several studies have shown that,pathogenic microorganisms as a kind of biocolloid,its transport will be controlled by a series of complex mechanism.In addition to the common hydrodynamic and hydrochemical conditions,microorganisms are also affected by itself characteristics,medium particles and environmental factors during the migration process.On this basis,the migration behaviours of microorganisms in saturated porous media and unsaturated porous media have been discussed,and the research focus in recent years have also been briefly summarized.At present,a great number of related researches about this topic have been published.However,due to the complexity of underground environment and the variability of microorganisms,it is necessary to further discuss the remediation of microorganism pollution in groundwater system.
