Özet

Constructed wetland is a popular treatment method for different sources of wastewaters being an alternative to conventional wastewater treatment methods that have operational and financial restrictions, especially for decentralized wastewater systems. A pilot-scale, continuous flow, subsurface flow wetland was constructed at the Cukurova University in Adana, Turkey. The system works on a multi-culture planting texture employing Typha latifolia, Junkus acutus and Iris versicolor. Removal efficiency of the system was observed for approximately one year with 1.2 m(3)/h steady inflow rate. Removal rates of 89.0 +/- 10.6%, 76.7 +/- 8.3% and 68.8 +/- 5.9% were achieved for TSS, COD and BOD5, respectively. A high removal (95.4 +/- 8.3%) for fecal coliform was also observed. The obtained results imply that constructed wetlands are suitable for treatment of wastewaters originating from campuses in and climate.
