An Application of Phytoremediation to River Pollution Remediation

To study the application of phytoremediation, the floating bed was constructed with thick bamboo tube on Guxin River in Hangzhou, and the potential of Eichornia crassipes and Lolium perenne L to serve as a phytoremediation plant in the cleaning up of contamination from polluted river was evaluated in this study. Eichhonia crassipes and Lolium perenne L were planted on the floating bed in turn. The results showed that NH3-N, COD, TP of study river reduced 48.6%, 20.0%, 63.3% respectively. Harvesting Eichhonia crassipes can carry quantities of contaminant from aquatic system. In which case, Phytoremediation is an effective way to remove organic matter from the polluted river.
