The removal affect of nitrogen and phosphorus were analyzed using a Acorus calamus var. angustatus. The nutrient concentration, growth stage of plants and the storage time of polluted water were considered. The results of this study were as follows: after an hour the content of nitrogen and phosphorus were considerably reduced in the Acorus calamus var. angustatus, while after two-four hours the rate of reduction was extremely low. This situation was the same in the early growth stage, growing stage and highest growth stage of the plant. The removal rate of nitrogen and phosphorus with the Acorus calamus var. angustatus was higher, when these two minerals remained in high levels of water. The Acorus calamus var. angustatus was more effective to remove nitrogen than that of phosphorus. The plant removed the most nitrogen and phosphorus when in the highest growth stage, but this was not clear in the growth stages. The removal rate was higher, in the case of moving polluted water to other plants after two days, than in the case of four days of growth in the same plants.
