A greenhouse experiment was conducted to study phosphorus retention rates in unvegetated and vegetated constructed wetland mesocosms planted with Juncus effusus (J. effusus), Carex lurida (C. lurida), and Dichanthelium acuminatum var. acuminatum (D. acuminatum). Mesocosms were either planted with monocultures of J. effusus, C. lurida, D. acuminatum or a mixed culture with all the above three plants or remained unvegetated. Mesocosms were dosed with 2.5mg/l of phosphorus once every month for 6months (June to November) in 2008 and 2009. Water samples were collected 8h after dosing and were analyzed for soluble inorganic phosphorus, particulate phosphorus, and total phosphorus. Sediment and plant samples were also collected with the water samples and were analyzed for total phosphorus. Vegetated treatments were effective in removing phosphorus and had at least 70% removal rate in 2008 and 2009. Unvegetated mesocosms showed 80% removal rate in 2008 and 65% in 2009. Monoculture of C. lurida and J. effusus along with the mixed culture treatment indicated at least 77% of removal rates. In conclusion, vegetated mesocosms had higher phosphorus removal rates compared to mesocosms with no vegetation. Therefore, the study suggests that phosphorus removal rates could be enhanced by using vegetated constructed wetlands with either monoculture or mixed culture stands of J. effusus and C. lurida.
