| Empirical Research on Removal of Pollutants from Road Runoff by Terrestrial Garden Plants in North China |

| Abstract: |
| Using plants to remove runoff pollutants is one of the main
application scenarios of phytoremediation. These researches mainly
focus on aquatic plants, while there are few researches of remediation
performance of terrestrial plants in cities in North China, especially the
road greening plants, which play an important role in removal of runoff
pollution at their source, and their long-term effect, that can not meet the
practical application requirements. At the same time, the researches on
the pollution risk caused by long-term concentrated infiltration of runoff
in biological detention facilities are still insufficient, and whether plants
can slow down the accumulation of pollutants is not clear. In this study,
pot experiments were conducted to analyze the removal rates of TN, TP
and CODCr in simulated runoff by 11 kinds of terrestrial garden plants
commonly used in road greening in North China, and those of TN and
TP accumulation in soil during the experiment. This study aims to help
landscape designers and environmental engineers to select specific plants
for ecological restoration |
