Abstract

Background and Objective: Synthetic wetlands are engineering systems that use natural plants, soils and organisms to purify municipal polluted water and remove nitrate. Materials and Methods: In this study, three systems were considerd as soil culture, three systems as plant cultivation on floating plates and three other systems without plant and porous bed as. The experiments were done three times within six months. The hydraulic retention times were 1, 3 and 5 days. The experimental design consisted of a factorial split-plot design. The analysis of variance showed that the efficiency of Nitrate removal was affected by the type of Constructed wetland, HRT, and temperature changes (p≤ 0. 01). Results: At the HRT of 1 day, the average efficiency of Nitrate removal by the soil culture, plant cultivation on floating plates and control were 14. 34%, 12. 09% and 10. 51%, respectively. At the HRT of 3 days, the average efficiencies were 17. 62%, 15. 76% and 13. 54%, respectively. At the HRT of 5 days, the efficiencies were increased and they were 17. 75%, 17. 66% and 16. 08%, respectively. Conclusion: The results showed that the soil culture were more efficinet in removing nitrate. Also, the Cyperus alternifolius plant has the potential of nitrate phytoremediation.
