In this study, for the treatment of rice field drainage water; The NO3-N and NH4-N treatment yields of Elodea Densa (Egeria), Lemna Minor (Duckweed), Micranthemum Micranthemoides (Micra), Pistia (Water Lettuce), Ceratophyllum Demersum (Foxtail) plants were investigated. Synthetic drainage water was created by analyzing the literature and the rice field drainage water contents taken from Samsun Bafra region. Artificial wetland studies were carried out separately in order to understand the treatment ability of each plant, and as a batch and continuous system at room temperature for the coexistence of all plants. Periodically pH, electrical conductivity (EC), dissolved oxygen (DO), nitrate (NO3-N), ammonium (NH4-N) values were measured in flower plugs. In the experiments carried out individually as a result of the studies, the wetland plant with the highest nitrate removal efficiency (77%) at the end of 1 day; Elodea Densa was found to be the plant with the highest ammonium removal efficiency (76%) as Pistia. It was observed that the plant treatment efficiency increased as the hydraulic waiting time increased. In their joint system study, at the end of the first day, the NO3-N removal efficiency was 40%, while the NH4-N removal efficiency was 51%. It was concluded that the wetland plants used successfully reduced the ammonium and nitrate content of the drainage water and showed resistance to the drainage water with high salinity content. In the wetland experiments carried out under continuous flow, at the end of the 16th day, NH4-N was reduced from 0.80 mg/L to 0.10 mg, while NO3-N was reduced from 1.90 mg/L to 1.40 mg/L. Studies have generally revealed the importance of plant type as well as waiting time.
