Transport Behavior of Microorganisms in Porous Media

The study of pathogenic microorganism transport in porous media is of great significance for protecting drinking water resources. On the basis of summarizing existing research data at home and abroad, the transport behavior of microorganisms in porous media was analyzed. Research has shown that pathogenic microorganisms, as a type of biological colloid, are subject to multiple transport mechanisms during their transport process. In addition to common hydrodynamic and hydrochemical conditions, microorganisms are also influenced by their own properties, medium particles, and chemotaxis during transport. This review aims to summarize the relevant research on the transport of microorganisms in porous media in recent years, gain a deeper understanding of the transport behavior of microorganisms in porous media, and provide theoretical basis for their practical application in groundwater and soil pollution remediation.
