ABSTRACT
As one of the technical measures of rainwater management, bioretention has received extensive attention by researchers due to its good pollutant removal effects, simple operating conditions, and low investment cost. The research status of the application of biological retention systems to the treatment of rainfall runoff pollutants at home and abroad in recent years is summarized. The research progress and theoretical achievements at home and abroad are discussed from three perspectives: biological retention system classification, decontamination mechanism, and influencing factors; and the current research status of the hydrological effect of biological retention systems. This article proposes the future research and development directions of bioretention and provides references for the practical application and promotion of bioretention.
