In an effort to protect surface and groundwater supplies from contamination, to assess the risk of microbial groundwater contamination and for the purpose of soil bioremediation, considerable efforts have been made to investigate biocolloid transport and retention in porous media. The current work provides an introductory overview of biocolloid transport and deposition in porous media so as to have a better understanding of the environmental behavior of biocolloids. In this review, biocolloid transport and deposition in porous media are discussed with an emphasis on transport and deposition mechanisms, numerical modeling and influencing factors. Moreover, major findings with respect to the forces acting on biocolloid transport and deposition are addressed, and research methods used to study biocolloid transport and deposition in porous media are also presented. Finally, based on the reported results, future research perspectives considering the microscopic pore scale study for biocolloid transport and deposition in porous media are also suggested.

为了保护地表水和地下水供应免受污染，评估微生物地下水污染的风险以及土壤生物修复的目的，已经做出了相当大的努力来研究生物胶体在多孔介质中的迁移和滞留。目前的工作提供了生物胶体在多孔介质中传输和沉积的介绍性概述，以便更好地了解生物胶体的环境行为。在这篇综述中，讨论了多孔介质中生物胶体的输运和沉积，重点是输运和沉积机制、数值模拟和影响因素。此外，还讨论了关于作用于生物胶体运输和沉积的力的主要发现，还介绍了用于研究多孔介质中生物胶体传输和沉积的研究方法。最后，基于报告的结果，还提出了考虑微观孔隙尺度研究的生物胶体在多孔介质中传输和沉积的未来研究前景。
