Abstract:
This study compared the NH4+-N and total phosphorus (TP) removal rate of calamus，Iris tectorum，reed and cattail in different periods，analyzed the changes of biomass，and nitrogen and phosphorus content of different plants，also discussed the factors affecting purification efficiency of plant.The results showed that the purification efficiency of plants in the fast growth period was higher than the purification efficiency of plant in the stable period.The NH4+-N removal rate of the four plants followed that cattail>Iris tectorum>calamus>reed，and the removal rate was 98.3%,98.2%,97.7%,96.8%，the TP removal rate of the four plants followed that cattail>calamus> Iris tectorum>reed，and the removal rate was 96.7%,96.4%,95.9%,95.2%.The NH4+-N and TP removal rate were related to the biomass of the underground part of plant.
